BroadcastReceiver receives multiple identical messages for one event

Question

I registered a receiver that listens to network events:

Answer 1

I have an application that uploads data when the user comes back online. Since my broadcast receiver can receive the intent multiple times, it can lead to the data being uploaded more than once. To handle this, I use a service that will not do anything if it is already running.

Broadcast Receiver:

public class ConnectionChangeReceiver extends BroadcastReceiver {
    private static boolean firstConnect = true;

    @Override
    public void onReceive(Context context, Intent intent) {
        final ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        final NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();
        if (activeNetInfo != null) {
            startService();
        }   
    }
}

Service:

public class MyService extends Service {
    private boolean mRunning;

    @Override
    public void onCreate() {
        super.onCreate();
        mRunning = false;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        if (!mRunning) {
            mRunning = true;
            uploadTheData();
        }
        return super.onStartCommand(intent, flags, startId);
    }
}
