How To Reuse Intents In Android

Hello All: I am creating an application in which I am using menus on every screen for the user to navigate. In my application, I have Screen1--> comes as home screen when the us

Ashwani,

I believe this can be done with a setFlags() call on your Intent using the FLAG_ACTIVITY_REORDER_TO_FRONT flag. If screen 1 still exists it will bring it to the foreground. The documentation doesn't seem to specify, but I assume it launches a new Activity of Screen 1 was killed.

Solution 2:

Take a look at android:launchMode attribute of element. Is "singleTop" launch mode is what you mean by "use existing home screen"? If you use "singleTop" the activity is not recreated, but receives onNewIntent() signal.
