Android检测虚拟机模拟器的方法
安卓模拟器检测的方法有很多,一些简单的信息能通过软件伪造,但是全方位多维度的伪造就相当难了,这里集合了几乎所有的安卓模拟器检测方法,为了测试检测效果,我下了多款市面常见的模拟器进行测试,经过测试,所有的模拟器都能被正确识别. 通过 Leakcanary 测试,没有发现内存泄漏问题.
检测模拟器的方法集合
检测设备信息
Build 类用来从系统属性中提取设备硬件和版本信息 通过分析这些信息和市面已有模拟器的信息进行对比 就可以做出初步判断

private boolean checkDeviceInfo() { boolean result = Build.FINGERPRINT.startsWith("generic") // 唯一识别码 || Build.MODEL.contains("google_sdk") // 版本 用户最终可以见的名称 || Build.MODEL.toLowerCase().contains("droid4x") || Build.MODEL.contains("Emulator") || Build.MODEL.contains("Android SDK built for x86") || Build.MANUFACTURER.contains("Genymotion") // 硬件制造商 || Build.HARDWARE.equals("goldfish") // 硬件名称 || Build.HARDWARE.equals("vbox86") || Build.PRODUCT.equals("sdk") // 整个产品的名称 || Build.PRODUCT.equals("google_sdk") || Build.PRODUCT.equals("sdk_x86") || Build.PRODUCT.equals("vbox86p") || Build.BOARD.toLowerCase().contains("nox") // 主板 || Build.BOOTLOADER.toLowerCase().contains("nox") // 系统启动程序版本号 || Build.HARDWARE.toLowerCase().contains("nox") || Build.PRODUCT.toLowerCase().contains("nox") || Build.SERIAL.toLowerCase().contains("nox"); // 硬件序列号 if (result) return true; result |= Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic"); if (result) return true; result |= "google_sdk".equals(Build.PRODUCT); return result; } |
检测包名
根据常见模拟器包名 通过 PackageManager.getLaunchIntentForPackage(包名) 判断Intent能否被解析 从而判断当时是不是模拟器环境
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
private boolean checkPackageName() { if (!isCheckPackage || mListPackageName.isEmpty()) { return false; } final PackageManager packageManager = mContext.getPackageManager(); for (final String pkgName : mListPackageName) { final Intent tryIntent = packageManager.getLaunchIntentForPackage(pkgName); if (tryIntent != null) { final List<ResolveInfo> resolveInfos = packageManager.queryIntentActivities(tryIntent, PackageManager.MATCH_DEFAULT_ONLY); if (!resolveInfos.isEmpty()) { return true; } } } return false; } |
检测移动网络运营商
虚拟机的手机运营商一般都是 android
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
private boolean checkOperatorNameAndroid() { if (ContextCompat.checkSelfPermission(mContext, Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED && isSupportTelePhony()) { TelephonyManager telephonyManager = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE); String operatorName = telephonyManager.getNetworkOperatorName(); if (operatorName.equalsIgnoreCase("android")) { log("Check operator name android is detected"); return true; } return false; } return false; } |
检测模拟器上特有文件
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
private boolean checkFiles(String[] targets, String type) { for (String pipe : targets) { File qemu_file = new File(pipe); if (qemu_file.exists()) { log("Check " + type + " is detected"); return true; } } return false; } |
检测模拟器属性
通过尝试查询设备系统属性中是否包含模拟器属性 来检测模拟器环境
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
private boolean checkQEmuProps() { int found_props = 0; for (Property property : PROPERTIES) { String property_value = getProp(mContext, property.name); if ((property.seek_value == null) && (property_value != null)) { found_props++; } if ((property.seek_value != null) && (property_value.contains(property.seek_value))) { found_props++; } } if (found_props >= MIN_PROPERTIES_THRESHOLD) { log("Check QEmuProps is detected"); return true; } return false; } |
检测虚拟机驱动
读取驱动文件, 检查是否包含已知的qemu驱动
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |
private boolean checkQEmuDrivers() { for (File drivers_file : new File[]{new File("/proc/tty/drivers"), new File("/proc/cpuinfo")}) { if (drivers_file.exists() && drivers_file.canRead()) { byte[] data = new byte[1024]; try { InputStream is = new FileInputStream(drivers_file); is.read(data); is.close(); } catch (Exception exception) { exception.printStackTrace(); } String driver_data = new String(data); for (String known_qemu_driver : QEMU_DRIVERS) { if (driver_data.contains(known_qemu_driver)) { log("Check QEmuDrivers is detected"); return true; } } } } return false; } |
检测网卡IP
Android模拟器默认的地址是10.0.2.15
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 |
private boolean checkIp() { boolean ipDetected = false; if (ContextCompat.checkSelfPermission(mContext, Manifest.permission.INTERNET) == PackageManager.PERMISSION_GRANTED) { String[] args = {"/system/bin/netcfg"}; StringBuilder stringBuilder = new StringBuilder(); try { ProcessBuilder builder = new ProcessBuilder(args); builder.directory(new File("/system/bin/")); builder.redirectErrorStream(true); Process process = builder.start(); InputStream in = process.getInputStream(); byte[] re = new byte[1024]; while (in.read(re) != -1) { stringBuilder.append(new String(re)); } in.close(); } catch (Exception ex) { log(ex.toString()); } String netData = stringBuilder.toString(); log("netcfg data -> " + netData); if (!TextUtils.isEmpty(netData)) { String[] array = netData.split("\n"); for (String lan : array) { if ((lan.contains("wlan0") || lan.contains("tunl0") || lan.contains("eth0")) && lan.contains(IP)) { ipDetected = true; log("Check IP is detected"); break; } } } } return ipDetected; } |
检测光传感器
由于光传感器模拟器不容易伪造 在这里判断设备是否存在光传感器来判断是否为模拟器
|
1 2 3 4 5 6 7 8 9 10 11 12 |
public static Boolean checkLightSensorManager(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; } } |
Build 类获取系统信息
- Product: 产品名称
- Manufacturer: 硬件制造商
- Brand: 品牌
- Device: 设备名称
- Model: 系统版本
- Hardware: 硬件名称
- FingerPrint: 唯一识别码
|
1 2 3 4 5 6 7 8 9 10 11 |
// 获取设备信息 public static String getDeviceInfo() { return "\tBuild.PRODUCT: \t" + Build.PRODUCT + "\n\n" + "\tBuild.MANUFACTURER: \t" + Build.MANUFACTURER + "\n\n" + "\tBuild.BRAND: \t" + Build.BRAND + "\n\n" + "\tBuild.DEVICE: \t" + Build.DEVICE + "\n\n" + "\tBuild.MODEL: \t" + Build.MODEL + "\n\n" + "\tBuild.HARDWARE: \t" + Build.HARDWARE + "\n\n" + "\tBuild.FINGERPRINT: \t" + Build.FINGERPRINT; } |
