Frage
My App have lost some data when screen rotated, so I cant display actionbar items dynamically.
Actually in screen rotation, very first time it called onCreate() then OnSuccess() and OnCreateOptionsMenu() and display actionbar Items properly. but next rotation it called OnCreateOptionsMmenu() before OnSuccess().
I've define a variable in OnSuccess() that used in OnCreateOptionsMenu(), so I cant display actionbarItem dynamically.
I've defined onRestoreInstanceState() and onSaveInstanceState() but those are get called later than OnCreateOptionMenu().
I have used ActionbarSherlock for this project. if someone can give a clue it would be grateful.
Here is my code

the issue is still exist!.
Actually in screen rotation, very first time it called onCreate() then OnSuccess() and OnCreateOptionsMenu() and display actionbar Items properly. but next rotation it called OnCreateOptionsMmenu() before OnSuccess().
Lösung
Have you tried below codes in your manifest..
<activity
android:name=".YourActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" android:windowSoftInputMode="adjustPan"/>
Andere Tipps
When your screen is rotated so the oncreate method again call for stooping this we use this android:configChanges="orientation|screenSize"in manifest file.
