Code Snippets

Here are some code snippets that demonstrate how to fix app crashes:

• Memory Leak Fix

  public class MyActivity extends AppCompatActivity {
  
  private static final String TAG = "MyActivity";
  
  
  
  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      // ...
  
      // Use the Android Memory Manager to identify and fix memory leaks
  
      android.util.Log.d(TAG, "Memory Leak: " + getMemoryUsage());
  
  }
  
  
  
  private long getMemoryUsage() {
  
      // Get the current memory usage
  
      long memoryUsage = Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory();
  
      return memoryUsage;
  
  }
  
  }

• Network Issue Fix

  public class MyActivity extends AppCompatActivity {
  
  private static final String TAG = "MyActivity";
  
  
  
  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      // ...
  
      // Use a VPN to bypass network issues
  
      // ...
  
  }
  
  }

• App Update Fix

  public class MyActivity extends AppCompatActivity {
  
  private static final String TAG = "MyActivity";
  
  
  
  @Override
