仅在物理设备而非模拟器上运行 Android 应用

Question

How can I make my app run only on a physical android device, not an emulator.

When the app starts I want to check if the device is a physical device or emulator. If it is an emulator, I want my app to stop.

How can I do this?

Answer 1

In the onCreate() method of your launch activity, you can check whether the device is running on an emulator and, if it is, just call finish() . To check whether you're running on an emulator, you can use something like the following code (taken from this answer ):

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);
}

You can find lots of other suggestions on the web for detecting an emulator environment. I don't know of any that are absolutely foolproof, but the above is pretty robust.

You can try something like below

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.HARDWARE.equals("vbox86")
                || Build.HARDWARE.toLowerCase().contains("nox")
                || Build.MODEL.contains("google_sdk")
                || Build.MODEL.contains("Emulator")
                || Build.MODEL.contains("Android SDK built for x86")
                || Build.MODEL.toLowerCase().contains("droid4x")
                || 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")
                || Build.PRODUCT.toLowerCase().contains("nox")
                || Build.BOARD.toLowerCase().contains("nox")
                || Build.BOOTLOADER.toLowerCase().contains("nox")
                || Build.SERIAL.toLowerCase().contains("nox");
    }

It's an update of the code used in the Flutter project(device info plugin). check it here

You can also use code below, It worked for me and the code is very less:

public static final String DSN_EMULATOR = "unknown";

  if(Build.SERIAL.equalsIgnoreCase(AppConstant.DSN_EMULATOR) || Build.SERIAL.contains("EMULATOR")) {
  // It's an emulator
}
