Question

I’m working in a app ,where I filter if screen is on or off and launch an activity when the screen is on, but sometime it launch the activity but the activity was started already , i would like to ask you if it was any way to know inside my app if an activity is already launched.

When i start the activity i added this code

intent11.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

Thank you so much.

I think that you can set variable with activity life cycle

class IAMActivity extends Activity {
    static boolean isStart = false;

  public void onStart() {
     super.onStart();
     isStart = true;
  } 
  public void onStop() {
     super.onStop();
     isStart = false;
   }
 }
