How can I detect when an Android application is running in the emulator?

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

How about this solution (class implementation of SystemProperties is available here):

fun isProbablyAnEmulator(): Boolean {
    return (Build.FINGERPRINT.startsWith("google/sdk_gphone_")
            && Build.FINGERPRINT.endsWith(":user/release-keys")
            && Build.MANUFACTURER == "Google" && Build.PRODUCT.startsWith("sdk_gphone_") && Build.BRAND == "google"
            && Build.MODEL.startsWith("sdk_gphone_")) // Android SDK emulator
            || 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")
            || "QC_Reference_Phone" == Build.BOARD  //bluestacks
            || Build.MANUFACTURER.contains("Genymotion")
            || Build.HOST.startsWith("Build") //MSI App Player
            || Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic")
            || Build.PRODUCT == "google_sdk"
            || SystemProperties.getProp("ro.kernel.qemu") == "1"// another Android SDK emulator check
}

Note that some emulators fake exact specs of real devices, so it might be impossible to detect it.

Here a tiny snippet you can make in the APK to show various things about it, so you could add your own rules:

        textView.text = "FINGERPRINT:${Build.FINGERPRINT}\n" +
                "MODEL:${Build.MODEL}\n" +
                "MANUFACTURER:${Build.MANUFACTURER}\n" +
                "BRAND:${Build.BRAND}\n" +
                "DEVICE:${Build.DEVICE}\n" +
                "BOARD:${Build.BOARD}\n" +
                "HOST:${Build.HOST}\n" +
                "PRODUCT:${Build.PRODUCT}\n"
