Understanding the “Android Emulator System UI Isn’t Responding” Error
Ever found yourself staring at a frozen Android emulator, desperately clicking and tapping, only to be met with the dreaded “System UI isn’t responding” message? It’s a common, yet frustrating, experience for anyone working with Android emulators. Let’s delve into what this error actually means, what it looks like in action, and the crucial role the System UI plays.
The Meaning of “System UI Isn’t Responding”
In the digital realm of Android emulation, the “System UI isn’t responding” error is essentially a polite way of saying the emulator’s core interface is having a complete meltdown. Think of it like your car’s dashboard suddenly freezing – you can’t see your speed, fuel level, or any other critical information. In the emulator, this translates to the operating system’s visual interface – the icons, the navigation buttons, the status bar, and everything else you see and interact with – becoming unresponsive.
The system is essentially struggling to process and display the graphical elements that make the emulator usable. This can happen due to various reasons, which we’ll explore later, but the core issue is a failure of the System UI to keep up with the demands placed upon it.
Common Symptoms of the Error
When the “System UI isn’t responding” error strikes, it manifests in a variety of annoying ways. The most immediate sign is the frozen screen. But the problems run deeper than just a visual freeze.
- Complete Freeze: The emulator’s display becomes completely static. No buttons respond, and the screen is locked on whatever was last displayed. You might still see the mouse cursor moving, but it won’t interact with anything on the screen.
- Delayed Responses: Sometimes, the emulator doesn’t freeze entirely, but everything becomes incredibly slow. Taps and clicks take an eternity to register, and animations stutter or lag severely. This can make the emulator practically unusable.
- Error Messages: The most obvious symptom is, of course, the “System UI isn’t responding” dialog box itself. This is often accompanied by options to “Wait” (which usually doesn’t work) or “Close App” (which often restarts the emulator).
- Partial Functionality: In some cases, parts of the UI might still work, while others are completely broken. For example, you might be able to pull down the notification shade but not interact with any of the notifications.
- Crashes and Restarts: The error can lead to the entire emulator crashing or restarting unexpectedly, leading to lost work or progress.
The Function of the Android Emulator’s System UI
The System UI is the visual heart and soul of the Android experience within the emulator. It’s responsible for managing and displaying everything you see on the screen.
Here’s a breakdown of its key functions:
- Displaying the User Interface: The System UI renders the graphical elements of the Android interface, including the status bar (showing time, battery, and notifications), the navigation bar (back, home, and recent apps buttons), app icons, and widgets.
- Handling User Input: It intercepts and processes user interactions like taps, swipes, and button presses, translating them into actions within the operating system.
- Managing System Notifications: The System UI is responsible for displaying notifications, alerts, and other system messages to the user.
- Controlling System Animations: It handles animations and transitions, such as opening and closing apps, switching between screens, and displaying visual feedback.
- Providing Accessibility Features: The System UI integrates with accessibility features like TalkBack, allowing users with disabilities to interact with the emulator.
The System UI is a complex component, and any issues within it can lead to the “System UI isn’t responding” error. Understanding its function is key to troubleshooting and resolving the problem.
Potential Causes of the System UI Freeze

Dealing with the “System UI isn’t responding” error in your Android emulator can be a frustrating experience, akin to trying to herd cats while juggling flaming torches. But understanding the underlying causes is the first step towards taming this digital beast. Let’s delve into the usual suspects that might be behind this pesky freeze, transforming frustration into informed action.
Resource Allocation and System UI Freezes
Resource allocation is the lifeblood of any operating system, including the Android emulator. Insufficient resources, like a starving artist trying to paint with a single crayon, can cripple the System UI.The allocation of CPU and RAM directly impacts the emulator’s performance.
- CPU Bottlenecks: Imagine your CPU as the brain of your computer. The emulator, demanding significant processing power, might overwhelm the CPU if it’s not up to the task. When the CPU becomes a bottleneck, the System UI suffers, leading to freezes and unresponsiveness. For instance, if you are running multiple emulators or resource-intensive applications simultaneously, the CPU is forced to prioritize tasks, potentially starving the emulator of the resources it needs.
- RAM Constraints: Think of RAM as the workbench where the CPU lays out its work. If the workbench (RAM) is too small, the CPU has to constantly swap data between the workbench and the storage room (hard drive), slowing everything down. The emulator, needing a substantial amount of RAM to function, can become sluggish and freeze if RAM is insufficient. Consider a scenario where you’re running a high-resolution emulator image on a machine with limited RAM; the emulator will struggle to allocate the necessary memory, leading to System UI freezes.
Outdated Emulator Versions and System Images
Staying current with updates is crucial, like keeping your car’s engine tuned. Outdated components can create all sorts of performance issues, and the emulator is no exception.The emulator’s software and the system images it runs on can both contribute to System UI freezes if they’re not up to date.
- Emulator Version: Think of the emulator version as the foundation of a building. Older versions may contain bugs and inefficiencies that lead to instability, including System UI freezes. These bugs are often fixed in newer releases, so updating is critical. Consider the Android emulator’s early days, where certain versions were notorious for performance issues; updating to a later version often resolved these problems.
- System Image: The system image is the blueprint for the Android OS that the emulator runs. Outdated system images may not be optimized for the emulator or may contain compatibility issues that trigger System UI freezes. A good example would be an emulator running an older Android version, like KitKat, on a modern host machine; you might experience more frequent freezes compared to running a newer Android version on the same machine.
Conflicting Software and Background Processes, Android emulator system ui isnt responding
The digital world can be a crowded place, with various programs vying for attention and resources. When software conflicts or background processes run amok, the System UI in your emulator can become a casualty.Identifying and managing these conflicts is vital to prevent the “System UI isn’t responding” error.
- Software Conflicts: Imagine two chefs trying to use the same oven simultaneously; things are bound to get messy. Conflicting software, like other emulators, resource-intensive applications, or even antivirus programs, can hog resources and interfere with the emulator’s operations, leading to System UI freezes. A common example is running the Android emulator alongside another virtual machine; the competition for CPU and RAM can easily trigger freezes.
- Background Processes: Background processes are like unseen workers toiling away behind the scenes. Some of these processes can consume significant resources, potentially starving the emulator of what it needs. A large number of background processes, especially those that are resource-intensive, can contribute to System UI freezes. Consider a situation where you have several programs, like cloud storage sync clients or automatic backup tools, running in the background while the emulator is active; these can drain resources and lead to the error.
Troubleshooting Steps

Dealing with the “Android Emulator System UI Isn’t Responding” error can be frustrating, but don’t fret! We’re going to walk through some initial checks to get your emulator back on track. These steps are designed to be straightforward and cover the most common culprits behind the System UI freeze. Think of it as a quick diagnostic session before we dive deeper into more complex solutions.
Initial Checks Checklist
Before you start tearing your hair out, let’s go through a quick checklist. This will help you systematically identify the issue and save you some time. It’s like checking the fuses before calling an electrician.
- Restart the Emulator: A simple restart can often resolve temporary glitches.
- Restart the Host Machine: Sometimes, the problem lies with your computer, not the emulator itself.
- Check Emulator Logs: These logs hold valuable clues about what’s going wrong.
- Verify Resource Usage: Ensure your host machine isn’t overloaded.
- Update Android Studio and SDK Tools: Outdated software can cause compatibility issues.
Restarting the Emulator and Host Machine
The “turn it off and on again” approach is surprisingly effective. Both the emulator and your host machine can get into a funk, and a restart can often clear the cobwebs.
Restarting the Emulator:
This is usually the first thing to try. Close the emulator window. In Android Studio, you can either click the “Stop” button in the running devices panel or select “File” -> “Close” and then select “Shut Down Emulator.” After a few moments, restart the emulator by clicking the “Run” button or by launching it again from the AVD Manager.
Restarting the Host Machine:
A host machine restart is more drastic, but sometimes necessary. This clears out temporary files and processes that might be interfering with the emulator. Save your work, close all applications, and restart your computer. After the reboot, try running the emulator again.
Checking Emulator Logs for Error Messages and Warnings
Emulator logs are your secret weapon. They contain a detailed record of everything happening within the emulator, including error messages and warnings that can pinpoint the source of the problem.
Accessing the Logs:
The location of the logs depends on the emulator and your Android Studio setup, but they are typically found in the “Logcat” window within Android Studio. To access Logcat, go to “View” -> “Tool Windows” -> “Logcat.” You might also find logs in the emulator’s directory within your project folder or in the emulator’s installation directory. The specific path can vary depending on your operating system and Android Studio version.
Interpreting the Logs:
Logcat displays a stream of messages. Look for messages marked with “ERROR,” “WARN,” or “FATAL.” These are the most likely indicators of problems. Examine the messages closely, noting the time, the process ID (PID), and the specific error description. Sometimes, the error message will directly indicate the cause, such as a missing library or a conflict with another application. Other times, you may need to research the error code or message online to find a solution.
Common error messages to watch for include: “System UI isn’t responding,” “ANR” (Application Not Responding), and errors related to graphics rendering or network connectivity.
Verifying the Emulator’s Resource Usage in the Host Operating System
The emulator is a resource hog. It consumes CPU, RAM, and disk space. If your host machine is struggling, the emulator is likely to suffer. Monitoring resource usage helps determine if your computer is the bottleneck.
Monitoring Resource Usage:
Use your operating system’s built-in tools to monitor resource usage. On Windows, use the Task Manager (Ctrl+Shift+Esc). On macOS, use Activity Monitor (found in Applications/Utilities). On Linux, use tools like `top`, `htop`, or `gnome-system-monitor`. Keep an eye on CPU usage, memory usage, and disk I/O.
If the CPU is constantly at 100%, or the memory usage is maxed out, it’s a sign that your host machine is overloaded.
Identifying the Culprit:
Look for the “emulator” process in the resource monitor. If the emulator is consuming a significant amount of resources, this could be the source of the problem. Also, check other applications that might be consuming resources, such as Chrome, other IDEs, or resource-intensive games. Close unnecessary applications to free up resources for the emulator. Consider increasing the amount of RAM allocated to the emulator in the AVD configuration settings.
If your host machine has limited RAM, you might need to close other applications to free up memory.
Troubleshooting Steps
Dealing with an unresponsive Android Emulator System UI can be frustrating, but thankfully, there are advanced troubleshooting methods you can employ to bring your emulator back to life. These techniques delve deeper than the initial fixes, targeting the core of the problem and providing more robust solutions. Let’s explore these advanced strategies to conquer the System UI freeze.

Clearing the Emulator’s Cache and Data
Like a computer, the emulator stores temporary files (cache) and application data. Over time, these can become corrupted or consume excessive resources, leading to System UI problems. Clearing the cache and data can often resolve these issues and restore smooth operation.
- Clearing App Cache: Within the emulator, go to “Settings” > “Apps.” Select the app causing issues or all apps if you suspect a general problem. Choose “Storage” and then “Clear Cache.”
- Clearing App Data: In the same “Storage” settings, you can also “Clear Data.” This will remove all data associated with the app, effectively resetting it to its initial state. Be cautious, as this will delete any saved settings, logins, or other user data.
- Clearing the Emulator’s Cache (Advanced): If clearing app caches doesn’t work, you can try clearing the entire emulator cache. This is typically done by deleting the emulator’s data files. The specific location of these files depends on your operating system and Android Studio configuration. Consult online resources for the exact file paths.
Troubleshooting Specific Issues Related to Graphics Drivers
Graphics drivers play a critical role in the emulator’s performance. Outdated, corrupted, or incompatible drivers can lead to System UI freezes, graphical glitches, and overall instability. This section provides insights into addressing graphics-related problems.

Dealing with Resource Constraints: Android Emulator System Ui Isnt Responding
Running an Android emulator can be like hosting a party – if you don’t manage the guest list (CPU and RAM) properly, things can quickly get out of hand, leading to a sluggish experience and, in our case, the dreaded “System UI isn’t responding” error. Efficient resource management is crucial for a smooth and enjoyable development experience. Let’s delve into how we can keep the party (emulator) running smoothly.
Managing CPU and RAM Allocation for the Android Emulator
The Android emulator, much like a hungry houseguest, needs a certain amount of resources to function properly. Allocating the right amount of CPU and RAM is the first step toward preventing the System UI from freezing.To configure these settings, you’ll typically access the emulator’s settings through the Android Virtual Device (AVD) Manager within Android Studio. Here’s a breakdown:
- RAM Allocation: The AVD Manager allows you to specify the amount of RAM the emulator can use. A good starting point is usually 2GB to 4GB, but this depends on your host machine’s RAM. If you have 16GB of RAM or more on your host, allocating 4GB to the emulator is often a safe bet.
- CPU Cores: You can also control the number of CPU cores the emulator utilizes. The default is often one core, but you can increase this based on your CPU’s capabilities. Using more cores can improve performance, but it also consumes more resources.
- Graphics Settings: The emulator’s graphics settings also play a role. Consider using “Hardware – GLES 2.0” or “Hardware – GLES 3.0” for better performance if your host machine’s graphics card supports it. Software rendering can be a fallback, but it’s generally slower.
Remember that over-allocating resources can starve your host machine, leading to overall system slowdown. Finding the right balance is key.
Methods to Reduce the Emulator’s Resource Consumption
Even with optimal allocation, the emulator can still be a resource hog. Here are some strategies to lighten its load:
- Emulator Skin: Using a smaller emulator skin (e.g., a smaller screen size) can reduce the amount of graphics processing required.
- Emulator Snapshot: Take advantage of emulator snapshots. Snapshots save the emulator’s state, allowing you to quickly resume from a previous point. This can be faster than a full boot each time.
- Close Unnecessary Apps: Inside the emulator, close any background apps you’re not actively using. This frees up RAM and CPU cycles.
- Use a System Image Optimized for Speed: Some system images are designed for performance. Consider using a system image like “Google APIs Intel Atom (x86)” for better speed, especially on Intel-based machines.
- Enable Quick Boot: Quick Boot is a feature that allows the emulator to start much faster. It’s often enabled by default, but it’s worth checking your AVD settings.
- Disable Animations: Within the emulator’s settings (Developer options), you can disable animations. This can slightly improve performance.
These tweaks can make a noticeable difference in the emulator’s responsiveness.
Guidance on Optimizing the Host Machine’s Performance
The host machine’s performance directly impacts the emulator’s speed. Here’s how to ensure your host is up to the task:
- Sufficient RAM: Make sure your host machine has enough RAM. 16GB or more is highly recommended for running the emulator efficiently, especially if you plan to run other applications simultaneously.
- Fast Storage: Use an SSD (Solid State Drive) for your operating system and Android Studio. SSDs provide significantly faster read/write speeds than traditional HDDs, which speeds up emulator boot times and overall performance.
- Update Drivers: Keep your graphics card drivers and other system drivers up to date. Outdated drivers can lead to performance bottlenecks.
- Close Unnecessary Applications: Close any resource-intensive applications running on your host machine while using the emulator. This includes web browsers with many tabs open, video editing software, and other demanding programs.
- Monitor Resource Usage: Use your operating system’s built-in tools (Task Manager on Windows, Activity Monitor on macOS) to monitor CPU, RAM, and disk usage. This can help you identify any bottlenecks.
- Enable Virtualization: Ensure that virtualization is enabled in your BIOS/UEFI settings. This allows the emulator to use hardware-assisted virtualization, which dramatically improves performance.
By optimizing your host machine, you provide the emulator with the resources it needs to function smoothly.
Scenario: Over-Allocated Emulator and System UI Issues
Imagine a developer with a laptop featuring 8GB of RAM. They allocate 6GB of RAM to the Android emulator and allocate 4 CPU cores, leaving very little for the host operating system and other applications. This developer, working on a complex app with multiple background processes, frequently experiences the “System UI isn’t responding” error. The host machine becomes sluggish, and even basic tasks like opening a web browser take a long time.
The emulator, starved of resources, struggles to keep up, leading to freezes and crashes. This scenario illustrates how over-allocating resources to the emulator can cripple both the emulator and the host machine, resulting in a frustrating development experience. The solution is to re-evaluate the resource allocation, reduce the emulator’s demands, and optimize the host machine’s performance. For instance, reducing the emulator’s RAM allocation to 3GB, closing unnecessary applications on the host, and using a faster storage drive would drastically improve the situation.
Graphics Driver Issues and Solutions
Let’s talk about the unsung heroes of your Android emulator experience: graphics drivers. They’re the silent powerhouses that translate the complex instructions of the emulator into the visual feast you see on your screen. When these drivers aren’t up to snuff, the “System UI isn’t responding” error can rear its ugly head, turning your development process into a frustrating slog.
Understanding the relationship between your graphics drivers and the emulator is key to a smoother, more enjoyable experience.
The Role of Graphics Drivers in Emulator Performance
Graphics drivers act as the intermediary between your operating system and your graphics card (GPU). They are crucial for translating the emulator’s instructions into visual output. Think of them as the translators of the digital world, converting code into the images, animations, and interactive elements you see within the Android emulator. Without a well-functioning graphics driver, the emulator struggles to render graphics efficiently, leading to performance bottlenecks, freezes, and the dreaded “System UI isn’t responding” error.
They handle the rendering of the user interface, the display of the Android OS, and the overall responsiveness of the emulator. Essentially, they determine how quickly and smoothly the emulator runs.

Consider Using a Different Emulator
If you’re consistently facing performance issues, explore other Android emulator options (e.g., Genymotion, NoxPlayer) that may offer better performance on your hardware.
Third-Party Software Conflicts
Sometimes, your Android emulator throws a digital tantrum not because of its own shortcomings, but because it’s having a spat with other software on your computer. Think of it like a crowded party where everyone’s trying to talk at once – things get messy quickly. Identifying and resolving these conflicts is key to a smooth emulator experience. Let’s dive into the potential troublemakers and how to restore peace.
Identifying Potential Conflicts with Other Software
The Android emulator, a complex piece of software, relies on various system resources. Other applications, particularly those that also demand significant resources or interact closely with the operating system, can interfere with its operation. This interference often manifests as the “System UI isn’t responding” error, slowdowns, or outright crashes.
Examples of Software Known to Cause Issues with Android Emulators
Several types of software are notorious for causing conflicts. It’s like a rogues’ gallery of digital villains, each with its own special brand of chaos.
- Virtualization Software: Programs like VMware, VirtualBox, and even other Android emulators (running simultaneously) can compete for virtualization resources, leading to instability. Imagine two chefs trying to use the same oven at the same time; the results are rarely delicious.
- Security Software: Antivirus programs and firewalls can sometimes block the emulator’s network access or interfere with its processes. This is often a matter of the security software mistaking the emulator for a threat.
- Graphics-Intensive Applications: Games, video editing software, and other programs that heavily utilize the graphics processing unit (GPU) can strain the host system, leaving fewer resources for the emulator. Think of it like a traffic jam; too many cars, and everything slows down.
- Development Tools: Other Integrated Development Environments (IDEs), debuggers, and monitoring tools can also clash with the emulator, especially if they try to access the same ports or system resources.
Diagnosing and Resolving Software Conflicts
Pinpointing the culprit can feel like detective work, but there are some techniques to help you solve the mystery.
- Close Unnecessary Applications: Start by closing any programs you don’t need, especially those listed above. This helps isolate the problem.
- Monitor Resource Usage: Use the Task Manager (Windows) or Activity Monitor (macOS) to observe CPU, memory, and disk usage. Look for any applications that are consuming an excessive amount of resources. If an application is hogging all the resources, it may be the cause of the problem.
- Test in Safe Mode: Restart your computer in Safe Mode. This loads only the essential drivers and services, which can help determine if a third-party application is the source of the issue. If the emulator runs smoothly in Safe Mode, you know a conflicting application is at fault.
- Disable or Uninstall Suspicious Software: If you suspect a particular application, try disabling it temporarily or, if necessary, uninstalling it. Test the emulator after each change to see if the problem is resolved.
- Update Software: Make sure your Android emulator, graphics drivers, and any potentially conflicting software are up to date. Updates often include bug fixes and compatibility improvements.
Methods to Isolate the Emulator from Potential Interference
Sometimes, you can’t completely remove a conflicting application. In such cases, there are ways to create a more harmonious environment for your emulator.
- Allocate Sufficient Resources: Ensure the emulator has enough CPU cores, RAM, and disk space allocated to it. This can often be adjusted in the emulator’s settings.
- Adjust Emulator Settings: Experiment with the emulator’s settings, such as graphics rendering mode (e.g., software or hardware) and emulator skin. Some settings may be more compatible with specific software configurations.
- Use a Dedicated User Profile: On Windows, you could create a separate user profile dedicated to Android emulator usage. This can isolate the emulator from other software installed in your main profile.
- Virtual Machine Configuration: If you’re using virtualization software, you can configure the virtual machine specifically for the emulator, allocating resources and isolating it from the host operating system.
- Consider Alternate Emulators: If persistent conflicts plague your primary emulator, consider trying a different Android emulator. Different emulators have varying levels of compatibility with third-party software.
Using the Emulator Command Line
Alright, let’s get down to the nitty-gritty and explore the power of the Android emulator command line. Think of it as the secret weapon for developers and testers, offering granular control and troubleshooting capabilities that the graphical interface simply can’t match. Mastering the command line opens up a world of customization and problem-solving, turning you into an emulator guru. It’s like having a backstage pass to the inner workings of your virtual Android device.
Launching and Configuring the Emulator
The command line is your portal to launching and configuring the Android emulator. You’ll be typing commands, but don’t worry, it’s not as intimidating as it sounds. We’ll break it down step-by-step.To launch the emulator, you’ll generally use the `emulator` command, followed by various options to customize its behavior. The basic syntax is:“`emulator @
`[options]` are a plethora of flags that allow you to tweak everything from the screen size to the network settings.
Let’s look at some fundamental examples:* Launching with a specific AVD: “` emulator @Pixel_4_API_30 “` This command launches the emulator using the AVD named “Pixel\_4\_API\_30”.* Launching with a specific screen size and density: “` emulator @Pixel_4_API_30 -screen width=1080 -screen height=2280 -density 440 “` This overrides the default screen settings of the “Pixel\_4\_API\_30” AVD, setting the width, height, and density.
This is useful for testing your app on different screen configurations.* Launching with a specific RAM size: “` emulator @Pixel_4_API_30 -memory 4096 “` This command allocates 4096MB (4GB) of RAM to the emulator. Be mindful of your host machine’s RAM; allocating too much can slow things down. Understanding these initial commands sets the stage for more complex configurations.
The emulator command line gives you ultimate control over the virtual device.
Useful Command-Line Options for Troubleshooting
Troubleshooting with the emulator command line is where the real magic happens. It allows you to diagnose problems and gain insights into the emulator’s behavior. Let’s delve into some essential options:* `-verbose`: This is your best friend when things go wrong. Adding `-verbose` to your launch command will provide detailed output about the emulator’s startup process, including any errors or warnings.
“` emulator @Pixel_4_API_30 -verbose “` This is especially helpful for pinpointing the source of crashes or initialization failures.* `-show-kernel`: This option displays the kernel messages during the emulator’s boot process. This is valuable for debugging low-level issues. “` emulator @Pixel_4_API_30 -show-kernel “`* `-wipe-data`: If your emulator is acting up, a data wipe might be the solution.
This option resets the emulator to its factory state, clearing all installed apps and user data. “` emulator @Pixel_4_API_30 -wipe-data “` Use this with caution, as it will erase everything on the virtual device.* `-logcat
“` emulator @Pixel_4_API_30 -logcat
W “` This filters the logcat to show only warnings and errors. Replace `W` with `V` (verbose), `D` (debug), `I` (info), `E` (error), or `F` (fatal) to adjust the log level.* `-qemu -s`: The `-qemu` option passes arguments directly to the QEMU emulator that powers the Android emulator. The `-s` option starts the emulator in a GDB server, allowing you to connect a debugger and step through the emulator’s code.
This is very advanced, but invaluable for debugging complex issues. “` emulator @Pixel_4_API_30 -qemu -s “` These options give you a comprehensive toolkit for troubleshooting, from identifying startup errors to diving into low-level debugging.
Collecting Diagnostic Information
Gathering diagnostic information is a critical step in troubleshooting. The emulator command line offers tools to collect crucial data about the emulator’s state.* Using `adb` for Logcat and Bug Reports: The Android Debug Bridge (adb) is your primary tool for collecting diagnostic information. You can use it to access logcat, take screenshots, and generate bug reports.
Collecting Logcat
“`bash adb logcat > logcat.txt “` This command captures the emulator’s logcat output and saves it to a file named “logcat.txt”. This file is a treasure trove of information about what’s happening on the emulator.
Generating Bug Reports
“`bash adb bugreport > bugreport.txt “` This command generates a comprehensive bug report that includes system logs, device information, and more. This is extremely helpful for identifying the root cause of issues.* Analyzing System Information: You can use adb to gather information about the emulator’s system.
Get Device Info
“`bash adb shell getprop “` This command displays a list of system properties, including the Android version, build number, and hardware information.
Check Memory Usage
“`bash adb shell dumpsys meminfo “` This command provides information about memory usage by different processes on the emulator. The collected information is invaluable for pinpointing the cause of errors, performance bottlenecks, or compatibility issues.
Launching an Emulator with Specific Settings
