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。

普遍检测代码如下：

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：

设备信息检测代码：

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)) {

                || Build.HARDWARE.contains("ranchu")) {
            return true;
        }
        if (Build.BRAND == null) {

        }
        if (Build.PRODUCT.equals("sdk")

            return true;
        }
        if (Build.HARDWARE.equals("goldfish")
                || Build.HARDWARE.equals("ranchu")) {
            return true;
        }
        if (Build.FINGERPRINT.startsWith("generic")
                || Build.FINGERPRINT.startsWith("unknown")

            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。

蓝牙检测代码：

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;
        }
    }
}

光传感器检测代码：

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检测代码：

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;
}
