“`pseudocode
// Import necessary libraries (example)
// import com.example.smsgateway.SMSGatewayClient; // Hypothetical SMS Gateway Client
// import com.example.smsgateway.SMSMessage; // Hypothetical SMS Message class

// 1. Initialize the SMS Gateway Client
SMSGatewayClient gatewayClient = new SMSGatewayClient(“YOUR_API_KEY”);

// 2. Create an SMS Message object
SMSMessage message = new SMSMessage();
message.setRecipient(“+15551234567”); // Replace with recipient’s phone number
message.setText(“Hello from my Android app!”);

// 3. Send the message
try
String messageId = gatewayClient.sendMessage(message);
System.out.println(“Message sent successfully. Message ID: ” + messageId);
// Handle success (e.g., update UI)
catch (SMSGatewayException e)
System.err.println(“Error sending message: ” + e.getMessage());
// Handle failure (e.g., display error to the user)

// Explanation of the pseudocode:
//
– The code initializes an SMS gateway client using your API key.
//
– It creates an SMS message object, specifying the recipient’s phone number and the message content.
//
– The `sendMessage` method sends the message to the gateway.
//
– The code handles both success and failure scenarios. Upon success, it retrieves a message ID.

Upon failure, it catches an exception and provides an error message.
“`

This pseudocode provides a basic structure. Actual implementations would need to handle network requests, JSON parsing (for the API response), and error handling based on the specific API documentation of the SMS gateway provider.
