java - 如何在android中获得超级用户权限时修复崩溃的应用程序

Question

我正在创建一个将以编程方式访问超级用户的应用程序。在这里我编写了一些代码，它将完美地执行命令，但我的应用程序将冻结并最终在一段时间后崩溃，请帮助我解决这个问题。这就是我所做的

public class MainActivity extends Activity {
    Button files;
    File path;
    String directory_name;
    EditText edit_text_files;
    FileOutputStream fos;
    String [] commands = new String[10];
    boolean su;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        try
        {

            Process process = Runtime.getRuntime().exec("su");
            DataOutputStream data_out = new DataOutputStream(process.getOutputStream());
            DataInputStream data_in = new DataInputStream(process.getInputStream());
            data_out.writeBytes("mkdir mnt/udisk/samplefolder"+"\n");
            data_out.flush();

            data_out.writeBytes("exit \n");
            data_out.flush();
            process.waitFor();

        }
        catch(Exception e)
        {
            Log.e("Commands Exception :", "executing commands exception");
        }
