Android not restoring instance state -

i know similar questions have been asked none of solutions questions have been working me.

when go ahead , try save state of app, state of edittext views not being saved , restored. went ahead , commented out , put in temporary string save when app loads again, oncreate() method not print 'restoring instance state'

in logcat output "saved instance state" , "oncreate" not "restoring instance state" or "onrestore" when restarting app.

go debug mode , see if oncreate being called. have android:configchanges set in manifest?
