Question

How to know in settings "Don't keep activities" option is enabled in ics via code. If it is in enabled,how to prevent the activity.

Note: I have used more activities in my application.Because of that settings if I move one activity to another the first activity is destroyed.I can save my data on the onSaveInstanceState. With out using saved instance state is there any way to do...

Answer 1

import the following package

import android.provider.Settings;

Then you can check if the option is enable using this code:

Settings.System.getInt(getContentResolver(),Settings.System.ALWAYS_FINISH_ACTIVITIES, 0);

and you can change it using this:

Settings.System.putInt(getContentResolver(),Settings.System.ALWAYS_FINISH_ACTIVITIES,  0);

Hope it helps
