在模拟器的文件系统中放入一个文件;由于该文件不会存在于真正的设备上，这应该是稳定的，可靠的，容易修复当它崩溃。

这个解决方案怎么样(SystemProperties的类实现在这里可用):

val isProbablyRunningOnEmulator: Boolean by lazy {
    // Android SDK emulator
    return@lazy ((Build.MANUFACTURER == "Google" && Build.BRAND == "google" &&
            ((Build.FINGERPRINT.startsWith("google/sdk_gphone_")
                    && Build.FINGERPRINT.endsWith(":user/release-keys")
                    && Build.PRODUCT.startsWith("sdk_gphone_")
                    && Build.MODEL.startsWith("sdk_gphone_"))
                    //alternative
                    || (Build.FINGERPRINT.startsWith("google/sdk_gphone64_")
                    && (Build.FINGERPRINT.endsWith(":userdebug/dev-keys") || Build.FINGERPRINT.endsWith(":user/release-keys"))
                    && Build.PRODUCT.startsWith("sdk_gphone64_")
                    && Build.MODEL.startsWith("sdk_gphone64_"))))
            //
            || 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")
            //bluestacks
            || "QC_Reference_Phone" == Build.BOARD && !"Xiaomi".equals(Build.MANUFACTURER, ignoreCase = true)
            //bluestacks
            || Build.MANUFACTURER.contains("Genymotion")
            || Build.HOST.startsWith("Build")
            //MSI App Player
            || Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic")
            || Build.PRODUCT == "google_sdk"
            // another Android SDK emulator check
            || SystemProperties.getProp("ro.kernel.qemu") == "1")
}

请注意，一些模拟器伪造真实设备的精确规格，因此可能无法检测到它。我已经添加了我能添加的东西，但我不认为有100%的方法来检测它是否真的是一个模拟器。

这里有一个你可以在APK中创建的小片段来展示关于它的各种事情，所以你可以添加自己的规则:

        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"

我只是寻找_sdk， _sdk_或sdk_，甚至只是sdk部分构建。产品:

if(Build.PRODUCT.matches(".*_?sdk_?.*")){
  //-- emulator --
}else{
  //-- other device --
}

使用这个函数:

 public static final boolean isEmulator() {

    int rating = 0;

    if ((Build.PRODUCT.equals("sdk")) || (Build.PRODUCT.equals("google_sdk"))
            || (Build.PRODUCT.equals("sdk_x86")) || (Build.PRODUCT.equals("vbox86p"))) {
        rating++;
    }
    if ((Build.MANUFACTURER.equals("unknown")) || (Build.MANUFACTURER.equals("Genymotion"))) {
        rating++;
    }
    if ((Build.BRAND.equals("generic")) || (Build.BRAND.equals("generic_x86"))) {
        rating++;
    }
    if ((Build.DEVICE.equals("generic")) || (Build.DEVICE.equals("generic_x86")) || (Build.DEVICE.equals("vbox86p"))) {
        rating++;
    }
    if ((Build.MODEL.equals("sdk")) || (Build.MODEL.equals("google_sdk"))
            || (Build.MODEL.equals("Android SDK built for x86"))) {
        rating++;
    }
    if ((Build.HARDWARE.equals("goldfish")) || (Build.HARDWARE.equals("vbox86"))) {
        rating++;
    }
    if ((Build.FINGERPRINT.contains("generic/sdk/generic"))
            || (Build.FINGERPRINT.contains("generic_x86/sdk_x86/generic_x86"))
            || (Build.FINGERPRINT.contains("generic/google_sdk/generic"))
            || (Build.FINGERPRINT.contains("generic/vbox86p/vbox86p"))) {
        rating++;
    }

    return rating > 4;

    }

检查答案，当使用LeapDroid, Droid4x或Andy模拟器时，没有一个可以工作，

适用于所有情况的方法如下:

 private static String getSystemProperty(String name) throws Exception {
    Class systemPropertyClazz = Class.forName("android.os.SystemProperties");
    return (String) systemPropertyClazz.getMethod("get", new Class[]{String.class}).invoke(systemPropertyClazz, new Object[]{name});
}

public boolean isEmulator() {
    boolean goldfish = getSystemProperty("ro.hardware").contains("goldfish");
    boolean emu = getSystemProperty("ro.kernel.qemu").length() > 0;
    boolean sdk = getSystemProperty("ro.product.model").equals("sdk");
    return goldfish || emu || sdk;
}

我从来没有找到一个很好的方法来判断你是否在模拟器中。

但如果你只是需要检测你是否在开发环境中，你可以这样做:

     if(Debug.isDebuggerConnected() ) {
        // Things to do in debug environment...
    }

希望对大家有所帮助....
