问题 I am expreiencing a strange problem with my application. When I am testing it on a real device (with Android 4.4.4) all my Buttons' text fields look how I wanted (lower case letters).

问题 I have a Android application which i compiled with AOSP(Kitkat) as android system application and it was running fine. My application is dependent on native code compiled with Android-NDK as 32 bit libraries.

问题 I'm trying to use the Android L Developer Preview SDK, specifically the Bluetooth Low Energy classes. I set compileSdkVersion 'android-L' , minSdkVersion 'L' , and targetSdkVersion 'L' .
