Version 1.0.1 is our first public release of the ArcGIS Runtime SDK for Android. With this initial release we use GLSurfaceView and OpenGL ES 2.0 API classes which is supported on Android 2.2 (API level 😎 and above. The older SDK you are referring to was a Beta release which did not have this dependency. Apps built with the release version of the SDK must be restricted to devices that support OpenGL ES 2.0. Here is link to OpenGL support in Android SDK for further reference.
