If so, what is a simple way to access it via java?
[Settings.Secure#ANDROID_ID](http://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID) returns the Android ID as an unique 64-bit hex string.
import android.provider.Settings.Secure;
private String android_id = Secure.getString(getContext().getContentResolver(),
Secure.ANDROID_ID);
