How can I detect when an Android application is ru

Question

I would like to have my code run slightly differently when running on the emulator than when running on a device. (For example, using 10.0.2.2 instead of a public URL to run against a development server automatically.) What is the best way to detect when an Android application is running in the emulator?

Answer 1

My recommendation:

try this from github.

Easy to detect android emulator

• Checked on real devices in Device Farm (https://aws.amazon.com/device-farm/)
• BlueStacks
• Genymotion
• Android Emulator
• Andy 46.2.207.0
• MEmu play
• Nox App Player
• Koplayer
• .....

How to use with an Example:

EmulatorDetector.with(this)
                .setCheckTelephony(true)
                .addPackageName("com.bluestacks")
                .setDebug(true)
                .detect(new EmulatorDetector.OnEmulatorDetectorListener() {
                    @Override
                    public void onResult(boolean isEmulator) {

                    }
                });

I tried several techniques, but settled on a slightly revised version of checking the Build.PRODUCT as below. This seems to vary quite a bit from emulator to emulator, that's why I have the 3 checks I currently have. I guess I could have just checked if product.contains("sdk") but thought the check below was a bit safer.

public static boolean isAndroidEmulator() {
    String model = Build.MODEL;
    Log.d(TAG, "model=" + model);
    String product = Build.PRODUCT;
    Log.d(TAG, "product=" + product);
    boolean isEmulator = false;
    if (product != null) {
        isEmulator = product.equals("sdk") || product.contains("_sdk") || product.contains("sdk_");
    }
    Log.d(TAG, "isEmulator=" + isEmulator);
    return isEmulator;
}

FYI - I found that my Kindle Fire had Build.BRAND = "generic", and some of the emulators didn't have "Android" for the network operator.

Answer 3

This works for me

public boolean isEmulator() {
    return Build.MANUFACTURER.equals("unknown");
}

Answer 4

I've collected all the answers on this question and came up with function to detect if Android is running on a vm/emulator:

public boolean isvm(){


        StringBuilder deviceInfo = new StringBuilder();
        deviceInfo.append("Build.PRODUCT " +Build.PRODUCT +"\n");
        deviceInfo.append("Build.FINGERPRINT " +Build.FINGERPRINT+"\n");
        deviceInfo.append("Build.MANUFACTURER " +Build.MANUFACTURER+"\n");
        deviceInfo.append("Build.MODEL " +Build.MODEL+"\n");
        deviceInfo.append("Build.BRAND " +Build.BRAND+"\n");
        deviceInfo.append("Build.DEVICE " +Build.DEVICE+"\n");
        String info = deviceInfo.toString();


        Log.i("LOB", info);


        Boolean isvm = false;
        if(
                "google_sdk".equals(Build.PRODUCT) ||
                "sdk_google_phone_x86".equals(Build.PRODUCT) ||
                "sdk".equals(Build.PRODUCT) ||
                "sdk_x86".equals(Build.PRODUCT) ||
                "vbox86p".equals(Build.PRODUCT) ||
                Build.FINGERPRINT.contains("generic") ||
                Build.MANUFACTURER.contains("Genymotion") ||
                Build.MODEL.contains("Emulator") ||
                Build.MODEL.contains("Android SDK built for x86")
                ){
            isvm =  true;
        }


        if(Build.BRAND.contains("generic")&&Build.DEVICE.contains("generic")){
            isvm =  true;
        }

        return isvm;
    }

Tested on Emulator, Genymotion and Bluestacks (1 October 2015).

Answer 5

How about this solution:

public static boolean isEmulator() {
    return Build.FINGERPRINT.startsWith("generic")
            || Build.FINGERPRINT.startsWith("unknown")
            || Build.MODEL.contains("google_sdk")
            || Build.MODEL.contains("Emulator")
            || Build.MODEL.contains("Android SDK built for x86")
            || Build.MANUFACTURER.contains("Genymotion")
            || (Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic"))
            || "google_sdk".equals(Build.PRODUCT);
}

Answer 6

Based on hints from other answers, this is probably the most robust way:

isEmulator = "goldfish".equals(Build.HARDWARE)
