Show push notification only when app is not running android

Question

In my application I have push notification integrated with GCM . Its working fine whenever notification comes its appearing. But push notification come even when user is inside the app. I want notifications to appear only when user is outside the app.

Here is my code for push notification:

GcmBroadcastReceiver

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    ComponentName comp = new ComponentName(GCMNotificationIntentService.class.getPackage().getName(), 
            GCMNotificationIntentService.class.getName());
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);
}
}

GCMnotificationIntentService.Class

public class GCMNotificationIntentService extends IntentService {

public static int notificationId = 10;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
private boolean login_status = false;


public GCMNotificationIntentService() {
    super("GcmIntentService");
}

public static final String TAG = GCMNotificationIntentService.class.getSimpleName();

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    // The getMessageType() intent parameter must be the intent you received
    // in your BroadcastReceiver.
    String messageType = gcm.getMessageType(intent);

    if ( !extras.isEmpty() ) { // has effect of unparcelling Bundle
        /*
         * Filter messages based on message type. Since it is likely that
         * GCM will be extended in the future with new message types, just
         * ignore any message types you're not interested in, or that you
         * don't recognize.
         */
        if ( GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType) ) {
            sendNotification("Send error: " + extras.toString());
        } else if ( GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType) ) {
            sendNotification("Deleted messages on server: " + extras.toString());
            // If it's a regular GCM message, do some work.
        } else if ( GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType) ) {
            sendNotification(extras.getString("message"));
            Log.i(TAG, "Received: " + extras.toString());
        }
    }
    // Release the wake lock provided by the WakefulBroadcastReceiver.
    GcmBroadcastReceiver.completeWakefulIntent(intent);
}

private void sendNotification(String msg) {

    mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this).setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle(getString(R.string.notification_title))
            .setStyle(new NotificationCompat.BigTextStyle().bigText(msg)).setContentText(msg);
    Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    mBuilder.setSound(uri);
    mBuilder.setContentIntent(contentIntent);
    mBuilder.setAutoCancel(true);
    mNotificationManager.notify(notificationId++, mBuilder.build());
}
}

In ManifestFile

 <receiver
        android:name=".GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="com.medlife.deliveryagent" />
        </intent-filter>
    </receiver>
  <service android:name=".GCMNotificationIntentService" />

Any suggestions would be highly appreciated!!!

Do something like this to check whether you app is in foreground or not by calling below method and depending on returning value true or false do your rest of work

public boolean checkApp(){
       ActivityManager am = (ActivityManager) this
                .getSystemService(ACTIVITY_SERVICE);

        // get the info from the currently running task
        List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);

        ComponentName componentInfo = taskInfo.get(0).topActivity;
        if (componentInfo.getPackageName().equalsIgnoreCase("YourPackage")) {
            return true;
        } else {
           return false;
        }
  }

Kotlin

 fun isAppRunning(context: Context, packageName: String): Boolean {
    val activityManager = context.getSystemService(Context.ACTIVITY_SERVICE) as ActivityManager
    val procInfos = activityManager.runningAppProcesses
    if (procInfos != null) {
        for (processInfo in procInfos) {
            if (processInfo.processName == packageName) {
                return true
            }
        }
    }
    return false
}
