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...

Thanks in advance..

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
