Before all, i am a rookie in Android, and i am using API 10 (Gingerbread).
I am developing a simple game with libgdx. But i just install everything for start to work and... in the AndroidManifest.xml this line:
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
Got the next error in console:_
error: Error: String types not allowed (at 'configChanges' with value 'keyboard|keyboardHidden|orientation|screenSize').
I have found in Stackoverflow this answer, i changed to API 13 and works... but i think there should be a better solution than don't make the app less compatible because one line of code (there is much people that still using Gingerbread). There is another way to fix this?
Configure your libgdx Android Manifest like this and specify both min and target sdk version:
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="19" />
You can use API 5 as the minimum android version as this is what libgdx still supports. Don't get confused about the meaning of the target sdk version: this basically means that you have tested it against latest android version, it doesn't mean that it won't run on previous versions, because you have specified a min sdk before. Rule of thumb: put min-sdk as low as possible and target-sdk as high as possible.
Configuring it that way your game should still run in old devices and using configChanges like this will work as well:
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
I have just recently launched a game with configurations like this and works like a charm even on Gingerbread ;-)
