如何凍結root用戶的Android設備上的應用程序

Question

我如何凍結/取消凍結 root用戶設備（如Titanium Backup應用程序）上的應用程序，以便無法從root用戶設備訪問我的應用程序。 有什么方法可以跟蹤設備是否已植根？

Answer 1

我正在使用RootTools庫執行禁用/啟用命令

CommandCapture command_enable = new CommandCapture(0,"pm enable "+ Package_Name);                           
RootTools.getShell(true).add(command_enable).waitForFinish();

CommandCapture command_disable = new CommandCapture(0,"pm disable "+ Package_Name);
RootTools.getShell(true).add(command_disable).waitForFinish();

您實際上可以嘗試運行root命令並捕獲響應並確定設備是否已root。

從這里獲取代碼並對其進行一些修改以滿足您的需求，我認為它可能像這樣：

public static boolean canRunRootCommands()
       {
          boolean retval = false;
          Process suProcess;

          try
          {
             suProcess = Runtime.getRuntime().exec("su");

             DataOutputStream os = new DataOutputStream(suProcess.getOutputStream());
             DataInputStream osRes = new DataInputStream(suProcess.getInputStream());

             if (null != os && null != osRes)
             {
                retval = true;

                /*
                 *if got to this point, its safe to assume the 
                 *device is rooted and here you can do something 
                 *to tell your app that su is present. Or you could 
                 *use the bool return of this function to know that the 
                 *device is rooted and make the app act different.
                 */

             }
          }
          catch (Exception e)
          {
             // Can't get root !
             // [...] meaning that the device is not rooted

             retval = false;
          }

          return retval;
       }

我尚未對此進行測試，但是我相信它將為您提供幫助。 或至少它將以正確的方式指出您。
