Checking if code is running on an Android emulator seems to be an inexact process. This helper traces all the (static String) variables inside the android.os.Build class. This may help you choose a workaround/hack of your choice when required. http://stackoverflow.com/questions/2799097/how-can-i-detect-when-an-android-application-is-running-in-t…
