Question

I have an issue with my android app when i use android:configChanges="orientation". I want to prevent reloading activity after changing acreen orientation (above xml param works in other app) but this time it fails.

The thing is, that i want my activity (SherlockActivity) to keep portrait on start, but after OnClickListener event i need to enable it with:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);

Is there any other method that should be run to prevent that reload?

The android:configChanges parameter should work (it worked for me flawlessly). Just a blind guess – if you’re targeting API level 13 or higher, you also have to include screenSize:

Caution: Beginning with Android 3.2 (API level 13), the “screen size”
also changes when the device switches between portrait and landscape
orientation. Thus, if you want to prevent runtime restarts due to
orientation change when developing for API level 13 or higher (as
declared by the minSdkVersion and targetSdkVersion attributes), you
must include the “screenSize” value in addition to the “orientation”
value. That is, you must decalare
android:configChanges=”orientation|screenSize”. However, if your
application targets API level 12 or lower, then your activity always
handles this configuration change itself (this configuration change
does not restart your activity, even when running on an Android 3.2 or
higher device).
