            String[] paths = (String[]) sm.getClass().getMethod("getVolumePaths", null).invoke(sm, null);
            for(int i = 0; i < paths.length; i++)
            {
                Log.i("iii", paths[i]);
                String status = (String) sm.getClass().getMethod("getVolumeState", String.class).invoke(sm, paths[i]);
                if(status.equals(android.os.Environment.MEDIA_MOUNTED))
                {
                    String txt = "测试成功.txt";
                    String sPath = paths[i] + File.separator + txt;
                    File file = new File(sPath);
