How to check is app in foreground from service?

Question

I need to show notification to user only if application is not in foreground. Here is my public class MyFirebaseMessagingService extends

FirebaseMessagingService {     @Override     public void onMessageReceived(RemoteMessage remoteMessage) {         if(applicationInForeground()) {             Map<String, String> data = remoteMessage.getData();             sendNotification(data.get("title"), data.get("detail"));         }      } 

need to implement applicationInForeground() method

Answer 1

You can control running app processes from android system service. Try this:

private boolean applicationInForeground() {     ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);     List<ActivityManager.RunningAppProcessInfo> services = activityManager.getRunningAppProcesses();     boolean isActivityFound = false;      if (services.get(0).processName             .equalsIgnoreCase(getPackageName()) && services.get(0).importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {         isActivityFound = true;     }      return isActivityFound; } 

Good luck.
