问题
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?
回答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" ... />
回答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.

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