How to find out from code if my Android app runs on emulator or real device?

Question

I have read this stackoverflow thread already and I tried using the code given in that answer to find out if I run my code on the emulator or on a real device:

import android.content.ContentResolver;
import android.provider.Settings.Secure;
...     
mTextView.setText(Secure.getString(getContentResolver(), Secure.ANDROID_ID));

On my real device it returns "2bccce3...", however on the emulator it does not return null, but also a string "bd9f8..."

Ideas how to find out if emulator or real device from code would be highly appreciated

Answer 1

This should do it:

boolean inEmulator = false;
String brand = Build.BRAND;
if (brand.compareTo("generic") == 0)
{
    inEmulator = true;
}

EDIT:

boolean inEmulator = "generic".equals(Build.BRAND.toLowerCase());

With the advent of the new Intel native emulator the above mentioned methods did not work any longer. Now 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;
}
