How to come back to First activity without its onCreate() called

Question

I have 3 activity . Activity A ,Activity B, Activity C. This is the flow A->B->C. Now i want to come to activity A from C .(i.e C->A) without getting its onCreate() called of Activity A.

so far my code is:But it will call onCreate() of ActivityA. I want to call Restart().

Intent intent=new Intent(ActivityC.this,ActivityA.class);
                intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(intent);
                finish(); 

Answer 1

Two cases:

1. If you want to keep other activities live and just want to bring A to front, just use intent flag FLAG_ACTIVITY_REORDER_TO_FRONT.

2. If you don't want to clear all activities and want existing instance of A at top, then use intent flags FLAG_ACTIVITY_CLEAR_TOP and FLAG_ACTIVITY_SINGLE_TOP.

Note : If you use only FLAG_ACTIVITY_CLEAR_TOP, then onCreate will be called.

Answer 2

Keep android:launchMode="singleTask" in manifest at activity declaretion

An Activity with singleTask launchMode is allowed to have only one instance in the system If instance already exists, i will not call 'onCreate' it will call 'onNewIntent' method. See http://androidsrc.net/android-activity-launch-mode-example/ for better understand about launch modes.
