Steps for Auto-Start Configuration

  1. Listen to Broadcast Messages:
    • Android applications can react to system events by listening to broadcast messages. This is achieved by registering broadcast receivers in your app.
  2. Handle BOOT_COMPLETED Broadcast:
    • The Android system emits a specific broadcast message, 'android.intent.action.BOOT_COMPLETED', when the device finishes booting.
    • By capturing this broadcast, your app can perform actions immediately after the device boots.
  3. Declare a Receiver in the Manifest:
    • To enable your app to receive the boot completion broadcast, declare a broadcast receiver in your app's 'AndroidManifest.xml' file.
    • In the receiver, specify an intent filter for 'android.intent.action.BOOT_COMPLETED'.
  4. Implement the Receiver:
    • In your receiver's code, define the actions to be taken when the boot completion broadcast is received. This could involve starting a service or launching an activity.

Code Example:

// Declare receiver in manifest file
<receiver android:name=".BootReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

// Receiver class
public class BootReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // Check if it is boot broadcast
        if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
            // Start service or activity
            Intent newIntent = new Intent(context, MyService.class);
            context.startService(newIntent);
        }
    }
}
