How to clear the activity stack in Android

Question

I have the following application flow in my Android app,

Login->Home->screen1->screen2->screen3->screen4-> logout

In the screen4 I have a log out button, which allows the user to logout from the application and re-login. When I re-login to the app, the previous data is still shown. Is there a way to start the application fresh when the user logs out from the app?

NOTE: all the above activities launch mode set to "single task",

Answer 1

See if that helps - http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_CLEAR_TOP (This and other flags)

Answer 2

You could set a static flag when the user clicks logout and in each activity check that flag in onResume() and if it's set call finish() . That's kind of hacky though.

Answer 3

Well I dont know it its that what you want but can finishing activity before starting another and storing login in Application Context can help?

Answer 4

Configure this for your activity in AndroidManifest.xml. The attribute is android:clearTaskOnLaunch .
