How can I detect if a device has ‘do not keep activities’ set in

  • 0

How can I detect if a device has ‘do not keep activities’ set in developer options.
I can’t find this value in the settings-class.

I need this setting to know, because when ‘do not keep activities’ is activated my app gets problem with it.
Example : I have a main-activity and a sub-activity. when I switch from main to sub and back from sub to main, then the main-activity will be started again. This is because the mainactivity was killed before. besause I do a lot of loading in my main-activity, the app is not usable when starting over and over.

Or is there any method to solve this problem ?
Without this setting activated, there is no problem.

    Is it possible to detect that flag by code ?

    Yes.

    In API Doc, it is called Settings.System.ALWAYS_FINISH_ACTIVITIES:

    If 1, the activity manager will aggressively finish activities and processes as soon as they are no longer needed. If 0, the normal extended lifetime is used.

    Constant Value: "always_finish_activities"

    To get the value in code:

    int value = Settings.System.getInt(getContentResolver(), Settings.System.ALWAYS_FINISH_ACTIVITIES, 0);

    Check out the source code to see how Settings.apk did this.
