Question

我有以下代码：

    String s;
    String FinalS = "";

    try {
            
            Process p = Runtime.getRuntime().exec(new String[] { "su", "-c", "netstat -au"});
            BufferedReader inputStream = new BufferedReader(new 
            InputStreamReader(p.getInputStream())); 



            // reading output stream of the command
            while ((s = inputStream.readLine()) != null) {
                //Log.d("", s);
                FinalS.concat(s);
            }

        } catch (Exception e) {
        e.printStackTrace();
        }

        Log.d("", FinalS);

当我在“ while”中使用“ Log.e”时，它可以正确打印，但是当我使用“ FinsalS”时，它不起作用，LogCat屏幕显示：

还有其他方法可以将.exec的结果仅保存在一个String中吗？我正在使用Android 10（API级别29），并且我的设备中具有root访问权限。感谢您的建议！

有没有一种方法可以只在一个String中保存“ Runtime.getRuntime（）。exec”？
