我的测试代码：

 1         Button btnShellCommand01 = (Button)findViewById(R.id.btnShellCommand01);
 2         btnShellCommand01.setOnClickListener(new View.OnClickListener()
 3         {
 4             @Override
 5             public void onClick(View v)
 6             {

 8                 File file = new File("/bin");
 9                 MsgAppendLn02("file : "+file.toString());

12                 else
