这篇文章主要介绍了Android模拟器的检测方法,在Android开发过程中,防作弊一直是老生常谈的问题,而模拟器的检测往往是防作弊中的重要一环,接下来我们来讲解有关于模拟器的检测方法,需要的朋友可以参考下

最近看到某客户端有一个检测模拟器的方法，我正常手机结果被判断是模拟器了，很好奇，于是找了一下原因。

普遍检测方法

public boolean isEmulator() {
    String url = "tel:" + "123456";
    Intent intent = new Intent();
    intent.setData(Uri.parse(url));
    intent.setAction(Intent.ACTION_DIAL);
    // 是否可以处理跳转到拨号的 Intent
    boolean canResolveIntent = intent.resolveActivity(mContext.getPackageManager()) != null;
    return Build.FINGERPRINT.startsWith("generic")
        || Build.FINGERPRINT.toLowerCase().contains("vbox")
        || Build.FINGERPRINT.toLowerCase().contains("test-keys")
        || Build.MODEL.contains("google_sdk")
        || Build.MODEL.contains("Emulator")
        || Build.SERIAL.equalsIgnoreCase("unknown")
        || Build.SERIAL.equalsIgnoreCase("android")
        || 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)
        || ((TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE))
            .getNetworkOperatorName().toLowerCase().equals("android")
        || ！canResolverIntent;
}

这个代码检测模拟器有两个问题：

1、拨号检测，Android10.0及以上均为false

2、Build.SERIAL，Android8.0以上均为unknown

这导致8.0以上系统均会被误判

推荐模拟器检测方法

设备信息检测

private static final String[] known_numbers = {"15555215554", "15555215556", "15555215558", "15555215560", "15555215562", "15555215564", "15555215566", "15555215568", "15555215570", "15555215572", "15555215574", "15555215576", "15555215578", "15555215580", "15555215582", "15555215584",};
private boolean detectEmulator() {
        if (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)) {
            return true;
        }
        if (Build.PRODUCT.equals("sdk") || Build.PRODUCT.equals("sdk_x86")
                || Build.PRODUCT.equals("vbox86p") || Build.PRODUCT.equals("emulator")) {
            return true;
        }
        if (Build.BOARD == null) {
            return true;
        }
        if (Build.BOARD.equals("unknown")
                || Build.BOARD.contains("android")
                || Build.BOARD.contains("droid")) {
            return true;
        }
        if (Build.DEVICE == null) {
            return true;
        }
        if (Build.DEVICE.equals("unknown")
                || Build.DEVICE.contains("android")
                || Build.DEVICE.contains("droid")) {
            return true;
        }
        if (Build.HARDWARE == null) {
            return true;
        }
        if (Build.HARDWARE.equals("goldfish")
                || Build.HARDWARE.equals("ranchu")
                || Build.HARDWARE.contains("ranchu")) {
            return true;
        }
        if (Build.BRAND == null) {
            return true;
        }
        if (Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic")) {
            return true;
        }
        if (Build.MANUFACTURER.equals("unknown")) {
            return true;
        }
        if (Build.MANUFACTURER.equals("Genymotion")) {
            return true;
        }
        if ((Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic"))
                || "google_sdk".equals(Build.PRODUCT)) {
            return true;
        }
        if (Build.PRODUCT == null) {
            return true;
        }
        if (Build.PRODUCT.equals("sdk")
                || Build.PRODUCT.equals("sdk_x86")
                || Build.PRODUCT.equals("vbox86p")
                || Build.PRODUCT.equals("emulator")) {
            return true;
        }
        if (Build.HARDWARE.equals("goldfish")
                || Build.HARDWARE.equals("ranchu")) {
            return true;
        }
        if (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)) {
            return true;
        }
        if (Build.PRODUCT == null) {
            return true;
        }
        if (Build.PRODUCT.equals("sdk")
                || Build.PRODUCT.equals("sdk_x86")
                || Build.PRODUCT.equals("vbox86p")
                || Build.PRODUCT.equals("emulator")) {
            return true;
        }
        if (Build.HARDWARE.equals("goldfish")
                || Build.HARDWARE.equals("ranchu")) {
            return true;
        }
        if (new File("/dev/socket/qemud").exists()
                || new File("/dev/qemu_pipe").exists()) {
            return true;
        }
        try {
            TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
            if (telephonyManager != null) {
                String deviceId = telephonyManager.getDeviceId();
                List<String> knownNumbers = Arrays.asList(known_numbers);
                if (knownNumbers.contains(deviceId)) {
                    return true;
                }
            }
        } catch (Exception e) {
        }
        return false;
    }

上述代码使用了多种方法来检测设备是否为模拟器，这些方法包括：

检测 Build.FINGERPRINT 是否以 “generic” 或 “unknown” 开头
检测 Build.MODEL 是否包含 “google_sdk”、“Emulator” 或 “Android SDK built for x86”
检测 Build.MANUFACTURER 是否为 “Genymotion”
检测 Build.PRODUCT 是否为 “sdk”、“sdk_x86”、“vbox86p” 或 “emulator”
检测 Build.BOARD 是否为 “unknown” 或包含 “android” 或 “droid”
检测 Build.DEVICE 是否为 “unknown” 或包含 “android” 或 “droid”
检测 Build.HARDWARE 是否为 “goldfish”、“ranchu” 或包含 “ranchu”
检测 Build.BRAND 是否以 “generic” 开头，且 Build.DEVICE 以 “generic” 开头
检测 Build.PRODUCT 是否为 “google_sdk”
检测是否存在文件 “/dev/socket/qemud” 或 “/dev/qemu_pipe”
检测设备的电话号码是否为已知的模拟器电话号码

上述方法都是基于固件信息的判断，通过测试发现很多模拟器都失效，参考网上的教程，还有蓝牙、光线传感器、cpu检测，配合上面的固件信息，基本可以搞定大部分模拟器。

蓝牙检测方法

public boolean notHasBlueTooth() {
    BluetoothAdapter ba = BluetoothAdapter.getDefaultAdapter();
    if (ba == null) {
        return true;
    } else {
        // 如果有蓝牙不一定是有效的。获取蓝牙名称，若为null 则默认为模拟器
        String name = ba.getName();
        if (TextUtils.isEmpty(name)) {
            return true;
        } else {
            return false;
        }
    }
}

光传感器检测方法

public static Boolean notHasLightSensorManager(Context context) {
    SensorManager sensorManager = (SensorManager) context.getSystemService(SENSOR_SERVICE);
    Sensor sensor8 = sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT); //光
    if (null == sensor8) {
        return true;
    } else {
        return false;
    }
}

CPU检测方法

public static boolean checkIsNotRealPhone() {
    String cpuInfo = readCpuInfo();
    if ((cpuInfo.contains("intel") || cpuInfo.contains("amd"))) {
        return true;
    }
    return false;
}
public static String readCpuInfo() {
    String result = "";
    try {
        String[] args = {"/system/bin/cat", "/proc/cpuinfo"};
        ProcessBuilder cmd = new ProcessBuilder(args);
        Process process = cmd.start();
        StringBuffer sb = new StringBuffer();
        String readLine = "";
        BufferedReader responseReader = new BufferedReader(new InputStreamReader(process.getInputStream(), "utf-8"));
        while ((readLine = responseReader.readLine()) != null) {
            sb.append(readLine);
        }
        responseReader.close();
        result = sb.toString().toLowerCase();
    } catch (IOException ex) {
    }
    return result;
}

以上检测方法也不是完全可行，随着Android系统的更新，模拟器的增多，我们需要具体研究对应的一些变动来更新上述代码。

我们检测要注意一个问题，不一定能检测出所有的模拟器，但是一定不能误杀真机。

总结

建议首先使用传感器进行可疑性判断

蓝牙, wifi, 电池可以作为辅助数据进行监听。

附加传感器类型代码

public String getSensorTypeName(int type) {
        switch (type) {
            case Sensor.TYPE_ACCELEROMETER:
                return "加速度传感器";
            case Sensor.TYPE_GYROSCOPE:
                return "陀螺仪传感器";
            case Sensor.TYPE_LIGHT:
                return "环境光线传感器";
            case Sensor.TYPE_MAGNETIC_FIELD:
                return "电磁场传感器";
            case Sensor.TYPE_ORIENTATION:
                return "方向传感器";
            case Sensor.TYPE_PRESSURE:
                return "压力传感器";
            case Sensor.TYPE_PROXIMITY:
                return "距离传感器";
            case Sensor.TYPE_TEMPERATURE:
                return "温度传感器";
            case Sensor.TYPE_GRAVITY:
                return "重场传感器";
            case Sensor.TYPE_LINEAR_ACCELERATION:
                return "线性加速度传感器";
            case Sensor.TYPE_ROTATION_VECTOR:
                return "旋转矢量传感器";
            case Sensor.TYPE_RELATIVE_HUMIDITY:
                return "湿度传感器";
            case Sensor.TYPE_AMBIENT_TEMPERATURE:
                return "温度传感器";
            case Sensor.TYPE_GAME_ROTATION_VECTOR:
                return "游戏旋转矢量传感器";
            case Sensor.TYPE_STEP_COUNTER:
                return "计步器";
            case Sensor.TYPE_GEOMAGNETIC_ROTATION_VECTOR:
                return "地磁旋转矢量传感器";
            case Sensor.TYPE_SIGNIFICANT_MOTION:
                return "特殊动作触发传感器";
            default:
                return "未知传感器";
        }
    }
