android execution in emulator or device?

Question

Is there any way to know if my application is running on the emulator or on the device ?

Answer 1

I am using this code snippet which works on both Intel and ARM emulators:

if (Build.MODEL.contains("google_sdk") ||
    Build.MODEL.contains("Emulator") ||
    Build.MODEL.contains("Android SDK")) {
  RunsInEmulator = true;
}

Answer 2

Secure.getString(getContentResolver(), Secure.ANDROID_ID); 

(where Secure is android.provider.Settings.Secure)

That value will be null on the emulator, non-null on devices.
