public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 处理广播
    }
}

// 在Activity或Service中动态注册
IntentFilter filter = new IntentFilter("com.example.MY_ACTION");
MyBroadcastReceiver receiver = new MyBroadcastReceiver();
registerReceiver(receiver, filter);

public class MyJobIntentService extends JobIntentService {
    @Override
    protected void onHandleWork(@NonNull Intent intent) {
        // 处理任务
    }
}

// 启动JobIntentService
Intent intent = new Intent(this, MyJobIntentService.class);
startService(intent);

public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 处理广播
    }
}

// 在Activity或Service中注册
IntentFilter filter = new IntentFilter("com.example.MY_ACTION");
MyBroadcastReceiver receiver = new MyBroadcastReceiver();
LocalBroadcastManager.getInstance(this).registerReceiver(receiver, filter);

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // 处理消息
    }
}
