Firebase Crashlytics是这样做的:

private static final String GOLDFISH = "goldfish";
private static final String RANCHU = "ranchu";
private static final String SDK = "sdk";
    
public static boolean isEmulator() {
    return Build.PRODUCT.contains(SDK)
        || Build.HARDWARE.contains(GOLDFISH)
        || Build.HARDWARE.contains(RANCHU);
}

if (Build.BRAND.equalsIgnoreCase("generic")) {
    // Is the emulator
}

所有BUILD引用都是BUILD。道具值，所以你必须考虑到如果你要把这个放到发布代码中，你可能会有一些根用户因为某种原因修改了他们的。实际上没有任何修改需要使用generic作为品牌，除非特别尝试模拟模拟器。

指纹是构建编译和内核编译签名。有一些构建使用通用的，通常直接来自谷歌。

在修改过的设备上，IMEI也有可能被归零，所以这是不可靠的，除非您完全阻止修改过的设备。

金鱼是所有其他设备扩展的基础android构建。每个Android设备都有一个init.金鱼.rc，除非被黑客攻击并出于未知原因删除。

无论您使用哪种代码来进行模拟器检测，我都强烈建议编写单元测试来覆盖所有构建。指纹,构建。硬件和构建。您所依赖的制造商值。下面是一些测试示例:

@Test
public void testIsEmulatorGenymotion() throws Exception {
    assertThat(
            DeviceUtils.isRunningOnEmulator(
                    "generic/vbox86p/vbox86p:4.1.1/JRO03S/eng.buildbot.20150217.102902:userdebug/test-keys",
                    "vbox86", "Genymotion")).isTrue();

    assertThat(
            DeviceUtils.isRunningOnEmulator(
                    "generic/vbox86p/vbox86p:5.1/LMY47D/buildbot06092001:userdebug/test-keys", "vbox86",
                    "Genymotion")).isTrue();
}

@Test
public void testIsEmulatorDefaultAndroidEmulator() throws Exception {
    assertThat(
            DeviceUtils.isRunningOnEmulator(
                    "generic_x86/sdk_google_phone_x86/generic_x86:5.0.2/LSY66H/1960483:eng/test-keys", "goldfish",
                    "unknown")).isTrue();

    assertThat(
            DeviceUtils.isRunningOnEmulator(
                    "Android/sdk_google_phone_x86_64/generic_x86_64:6.0/MASTER/2469028:userdebug/test-keys",
                    "ranchu", "unknown")).isTrue();
}

@Test
public void testIsEmulatorRealNexus5() throws Exception {
    assertThat(
            DeviceUtils.isRunningOnEmulator("google/hammerhead/hammerhead:6.0.1/MMB29K/2419427:user/release-keys",
                    "hammerhead", "LGE")).isFalse();
}

.．.下面是我们的代码(为了简洁起见，删除了调试日志和注释):

public static boolean isRunningOnEmulator() {
    if (sIsRunningEmulator == null) {
        sIsRunningEmulator = isRunningOnEmulator(Build.FINGERPRINT, Build.HARDWARE, Build.MANUFACTURER);
    }

    return sIsRunningEmulator;
}

static boolean isRunningOnEmulator(String fingerprint, String hardware, String manufacturer) {
    boolean isEmulatorFingerprint = fingerprint.endsWith("test-keys");
    boolean isEmulatorManufacturer = manufacturer.equals("Genymotion")
            || manufacturer.equals("unknown");

    if (isEmulatorFingerprint && isEmulatorManufacturer) {
        return true;
    } else {
        return false;
    }
}

试试这个方法。

在谷歌和Genymotion模拟器上测试。

public Boolean IsVM() {
    String radioVersion = android.os.Build.getRadioVersion();
    return radioVersion == null || radioVersion.isEmpty() || radioVersion.equals("1.0.0.0");
}

Firebase Crashlytics是这样做的:

private static final String GOLDFISH = "goldfish";
private static final String RANCHU = "ranchu";
private static final String SDK = "sdk";
    
public static boolean isEmulator() {
    return Build.PRODUCT.contains(SDK)
        || Build.HARDWARE.contains(GOLDFISH)
        || Build.HARDWARE.contains(RANCHU);
}

用下面的代码来判断你的应用是否使用了调试键?它没有检测模拟器，但它可能为您的目的工作?

public void onCreate Bundle b ) {
   super.onCreate(savedInstanceState);
   if ( signedWithDebugKey(this,this.getClass()) ) {
     blah blah blah
   }

  blah 
    blah 
      blah

}

static final String DEBUGKEY = 
      "get the debug key from logcat after calling the function below once from the emulator";    


public static boolean signedWithDebugKey(Context context, Class<?> cls) 
{
    boolean result = false;
    try {
        ComponentName comp = new ComponentName(context, cls);
        PackageInfo pinfo = context.getPackageManager().getPackageInfo(comp.getPackageName(),PackageManager.GET_SIGNATURES);
        Signature sigs[] = pinfo.signatures;
        for ( int i = 0; i < sigs.length;i++)
        Log.d(TAG,sigs[i].toCharsString());
        if (DEBUGKEY.equals(sigs[0].toCharsString())) {
            result = true;
            Log.d(TAG,"package has been signed with the debug key");
        } else {
            Log.d(TAG,"package signed with a key other than the debug key");
        }

    } catch (android.content.pm.PackageManager.NameNotFoundException e) {
        return false;
    }

    return result;

}
