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:

Answer 1

There's a rather old thread on Android Developers group that suggests checking the number of sensors on the device. Something like this might work:

SensorManager manager = (SensorManager) getSystemService(SENSOR_SERVICE);
if (manager.getSensorList(Sensor.TYPE_ALL).isEmpty()) {
    // running on an emulator
} else {
    // running on a device
}

I haven't tried this, so I have no idea how reliable the suggestion is. (Perhaps some emulators now report some sensors; perhaps some devices report no sensors. [Is there an Android toothbrush yet?]) But it can't be worse than checking for a null ANDROID_ID (which doesn't work as of 2.2).

P.S. Another thread claims that as of 2.2, the ANDROID_ID for the emulator is always "9774D56D682E549C". However, you are apparently getting some other hex string, so I don't think this is right, either.

P.P.S. Other suggestions I haven't tried are here. One that seems particularly nice (if it works) is:

if (android.os.Build.MODEL.equals(“google_sdk”)) {
   // emulator
} else {
   //not emulator
}

Answer 2

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;
}

As of writing this, nothing in this thread worked for the Bluestacks 4 emulator except trying to check for sensors. And so I checked the battery temperature using this gist. It should return 0.0 which means it does not have a battery temperature (and therefore it's an emulator).

public float getCpuTemp() {
    Process process;
    try {
        process = Runtime.getRuntime().exec("cat sys/class/thermal/thermal_zone0/temp");
        process.waitFor();
        BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line = reader.readLine();
        float temp = Float.parseFloat(line) / 1000.0f;
        return temp;
    } catch (Exception e) {
        e.printStackTrace();
        return 0.0f;
    }
}

Answer 4

Following one is correctly detect my emulator

if (Build.BRAND.equalsIgnoreCase("generic")) {
              //"YES, I am an emulator"
       } else {
              //"NO, I am NOT an emulator"
       }

Answer 5

This is the standard google flutter emulator check :

public boolean isEmulator() {
    return (Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic"))
            || Build.FINGERPRINT.startsWith("generic")
            || Build.FINGERPRINT.startsWith("unknown")
            || Build.HARDWARE.contains("goldfish")
            || Build.HARDWARE.contains("ranchu")
            || Build.MODEL.contains("google_sdk")
            || Build.MODEL.contains("Emulator")
            || Build.MODEL.contains("Android SDK built for x86")
            || Build.MANUFACTURER.contains("Genymotion")
            || Build.PRODUCT.contains("sdk_google")
            || Build.PRODUCT.contains("google_sdk")
            || Build.PRODUCT.contains("sdk")
            || Build.PRODUCT.contains("sdk_x86")
            || Build.PRODUCT.contains("vbox86p")
            || Build.PRODUCT.contains("emulator")
            || Build.PRODUCT.contains("simulator");
}

Answer 6

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());
