Answer 1

Just add to your manifest (to this activity):

android:launchMode="singleTask" 

or:

android:launchMode="singleInstance"

Your activity won't recreacte any more. It will be saved.

Answer 2

declare:

SharedPrefernces mPrefs;

in on create:

mPrefs = getSharedPreferences("some name", 0);

to use value:

int value = mPrefs.getInt("value name",0);

to save value:

mPrefs.edit().putInt("value name",value);
mPrefs.edit().commit();
