Android multiple activity tasks when application is killed -

-

the app has 2 tasks of activities:

  • task 1
    • activity (launcher)
    • activity b
  • task 2
    • activity c <---- that's stack points @ in example.

now try that:

  1. go recent apps carrousel (you know clicking button on right of home button in newer phones).
  2. swipe apps out.
  3. your application killed , new application instance created (application#oncreate() called).
  4. android tries show activity c of task 2.

the funny thing if you're here:

  • task 1
    • activity (launcher)
    • activity b <---- here

...and repeat scenario, application killed , android goes home screen think should.

in short, looks android not clear tasks when killing application. true in precise scenario. go settings > applications > app > force stop, , see clear tasks.

anything can force android kill tasks when killing application?

after looking @ how recent apps handled on android sdk (see source here line 135 http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.1_r1/com/android/systemui/recent/recenttasksloader.java?av=f#135)

i understood (and tested) if provide activity c icon , label such:

<activity     android:name=".activityc"     android:label="activity title"     android:icon="@drawable/ic_icon" </activity>

you see 2 apps (tasks really) in recent apps carrousel.

now i'm thinking use case should not use different tasks because it's seen app android's standpoint.
