您如何(以编程方式)确定Android设备是否:已扎根运行软件或rom的破解副本.

How do you determine (programmatically) if an Android device is: rooted Running a cracked copy of your software or rom.

我的数据库中有一些敏感信息，我希望在手机扎根时对它进行加密，以使用户可以访问数据库.我该如何检测?

I have some sensitive information in my database, and I would like to encrypt it when the phone is rooted aka the user has access to the database. How do I detect that?

推荐答案

生根检测是一种猫捉老鼠的游戏，很难使生根检测在所有情况下都适用于所有设备.

Rooting detection is a cat and mouse game and it is hard to make rooting detection that will work on all devices for all cases.

请参见 Android根啤酒 https://github.com/scottyab/rootbeer用于高级根检测，它也使用JNI和编译到.so本机库中的本机CPP代码.

See Android Root Beer https://github.com/scottyab/rootbeer for advanced root detection which also uses JNI and native CPP code compiled into .so native library.

如果您需要一些简单和基础生根检测，请检查以下代码:

If you need some simple and basic rooting detection check the code below:

  /**
   * Checks if the device is rooted.
   *
   * @return <code>true</code> if the device is rooted, <code>false</code> otherwise.
   */
  public static boolean isRooted() {

    // get from build info
    String buildTags = android.os.Build.TAGS;
    if (buildTags != null && buildTags.contains("test-keys")) {
      return true;
    }

    // check if /system/app/Superuser.apk is present
    try {
      File file = new File("/system/app/Superuser.apk");
      if (file.exists()) {
        return true;
      }
    } catch (Exception e1) {
      // ignore
    }

    // try executing commands
    return canExecuteCommand("/system/xbin/which su")
        || canExecuteCommand("/system/bin/which su") || canExecuteCommand("which su");
  }

  // executes a command on the system
  private static boolean canExecuteCommand(String command) {
    boolean executedSuccesfully;
    try {
      Runtime.getRuntime().exec(command);
      executedSuccesfully = true;
    } catch (Exception e) {
      executedSuccesfully = false;
    }

    return executedSuccesfully;
  }

可能并不总是正确的. 2014年在约10种设备上进行了测试.

Probably not always correct. Tested on ~10 devices in 2014.
