Project creation step by step
- git clone https://github.com/android/platform_development.git
- import platform_development/samples/ApiDemos to Android Studio
- Rename preference_switch to preference_switch.xml
- Exclude MmsMessagingDemo.java and MmsWapPushReceiver.java from compilation, because thoes classes tried to reference com.google.android.mms which is not included in ApiDemos
- Add try/catch for DocumentsContract series API in DocumentsSample.java
