Restoring previous state on android when switching between activities

Question

I have two activities and I can change from one activity to other by swiping (i am overriding overridePendingTransition() in base activity which two activities are being inherited) and I am using intents to switch between activities. But when I come from second activity to first, I don't want to create a new intent rather I use previous state. (I have lots of data on UI of both activities, I prefer not to redraw everything and sharing Bundle between activities). When I am going to second activity I did not destroy the first one. How can I restore that state, basically UI should not change?

use `finish();` in second activity instead of using Intent to call first activity. — W I Z A R D, Apr 15 '14 at 08:51

You can switch between 2 activities like this:

In activity A, when you want to switch to activity B do:

Intent intent = new Intent(this, B.class);
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(intent);

In activity B, when you want to switch to activity A do:

Intent intent = new Intent(this, A.class);
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(intent);
