这对我很有用

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

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);
}

一个常见的是Build.FINGERPRINT.contains("generic")

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;

} 

不知道是否有更好的方法来检测emu，但模拟器将在根目录下有init.金鱼.rc文件。

它是特定于模拟器的启动脚本，在非模拟器构建中不应该出现。

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"
