Start new Activity and finish current one in Android? [duplicate]

• How to finish current activity in Android 7 answers

Currently I'm starting a new Activity and calling finish on a current one.

Is there any flag that can be passed to Intent that enables finishing current Activity without a need to call finish manually from code?

Answer 1

You can use finish() method or you can use:

android:noHistory="true"

And then there is no need to call finish() anymore.

<activity android:name=".ClassName" android:noHistory="true" ... />

Answer 2

Use finish like this:

Intent i = new Intent(Main_Menu.this, NextActivity.class);
finish();  //Kill the activity from which you will go to next activity 
startActivity(i);

FLAG_ACTIVITY_NO_HISTORY does the opposite. New activity is not saved in history, whereas OP wants previous Activity being finished.

Answer 3

FLAG_ACTIVITY_NO_HISTORY when starting the activity you wish to finish after the user goes to another one.
