我已經運行了以下代碼行和一些類似的解決方案，但似乎沒有任何效果：    StringBuilder cmdOut = new StringBuilder();    Process process;   try {       process = Runtime.getRuntime().exec("adb shell");       InputStreamReader r = new        InputStreamReader(process.getInputStream());       BufferedReader bfreader = new BufferedReader(r);       char [] buf  = new char[4096];       int nRead = 0;       while((nRead = bfreader.read(buf)) > 0)       {           cmdOut.append(buf,0,nRead);       }       bfreader.close();       try{           process.waitFor();       }       catch (InterruptedException e)       {           e.printStackTrace();       }   }   catch (IOException e)   {       e.printStackTrace();   }but when i run this i got the following error:I have looked after every answer but I have not found any working solution java.io.IOException: Cannot run program "adb": error=13, Permission denied如果有人有任何可行的解決方案，請通過示例分享。
