Android remove Activity from back stack

FLAG_ACTIVITY_CLEAR_TOP clears your Activity stack , you can use the code below:

Intent intent = new Intent(this, Activity.class);intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);startActivity(intent);

Remember that this flag clears just Intermediate Activities , for example if you have A,B,C in your Back Stack then going from C Activity to D with this flag this does not clear Back Stack and the Stack would be A,B,C,D but if you go from Activity D to Activity A with this flag , B,C,D Activities will pop up from the stack and you will have just A in the Back Stack .

I would suggest that you use startActivityForResult(), instead of simply startActivity(), when you launch the EditDegreePlan-Activity, as described in the Android tutorials.

In the EditDegreePlan-Activity you then call

setResult(RESULT_OK);finish();

If you don't expect any data from the EditDegreePlan-Activity, then you don't necessarily have to implement the onActivityResult.

simple solution for API >= 15 to API 23user activity name in intent.

 Intent nextScreen = new Intent(currentActivity.this, MainActivity.class); nextScreen.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | IntentCompat.FLAG_ACTIVITY_CLEAR_TASK); startActivity(nextScreen); ActivityCompat.finishAffinity(currentActivity.this);
