My application has a transparent activity and every time I start that activity I would like to show it over launcher only (i.e) if any other app is open, I would like to push that app into the recents stack and show my application over launcher only. Is it possible to do this programmatically?

Actual Use case :

I am trying to start this activity from lockscreen and the issue is if the device was locked when another application was running and I try to start this activity from lockscreen at that point, we see this transparent activity over the application that was running prior to the device being locked.

  • on your app start, you can start the launcher using intent, and then start your transparent activity using another intent – Vladyslav Matviienko Sep 15 '17 at 06:40

When you call the activity, then you have to add Category_home so that you activity will always be on the launcher activity.

Intent intent = new Intent(Intent.ACTION_MAIN);
intent .addCategory(Intent.CATEGORY_HOME);
intent .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent (startMain);
