Answer 1

Check this post - and try to understand how to save data in preference. Then in your Activity

@Override
protected void onPause() {
super.onPause();
 // save seekBarPgrogress to preference here.
}    

@Override
protected void onResume() {
super.onResume();
// load seekBarPgrogress from preference here.
// and call seek.setProgress(position);
}

Hope its help

Save seekbar progress to shared preference in onPause and set seekbar progress from shared preference in onResume
