Question

How can a Service check if one of it's application's Activity is running in foreground?

Answer 1

Use the below method with your package name. It will return true if any of your activities is in foreground.

public boolean isForeground(String myPackage) {
    ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    List<ActivityManager.RunningTaskInfo> runningTaskInfo = manager.getRunningTasks(1); 
    ComponentName componentInfo = runningTaskInfo.get(0).topActivity;
    return componentInfo.getPackageName().equals(myPackage);
}

Update:

Add Permission:

<uses-permission android:name="android.permission.GET_TASKS" />
