在Android App中使用su权限执行adb命令

入正题，具体实现如下。
贴上代码：

    public static String exec(String command) {

        Process process = null;
        BufferedReader reader = null;
        InputStreamReader is = null;
        DataOutputStream os = null;

        try {
            process = Runtime.getRuntime().exec("su");
            is = new InputStreamReader(process.getInputStream());
            reader = new BufferedReader(is);
            os = new DataOutputStream(process.getOutputStream());
            os.writeBytes(command + "\n");
            os.writeBytes("exit\n");
            os.flush();
            int read;
            char[] buffer = new char[4096];
            StringBuilder output = new StringBuilder();
            while ((read = reader.read(buffer)) > 0) {
                output.append(buffer, 0, read);
            }
            process.waitFor();
            return output.toString();
        } catch (IOException | InterruptedException e) {
            throw new RuntimeException(e);
        } finally {
            try {
                if (os != null) {
                    os.close();
                }
                
                if (reader != null) {
                    reader.close();
                }

                if (is != null) {
                    is.close();
                }

                if (process != null) {
                    process.destroy();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
