我使用Raspberry Pi在启动时自动显示网页.
问题是:一旦覆盆子启动,Midori就会启动,但我的消息是"无法解析主机名......".
当我在启动后30秒更新网页时,它会正确显示.
我怎么能在X秒后推迟推出Midori?
我用我的网页启动 /etc/xdg/lxsession/LXDE/autostart
我使用我的应用程序时出现此错误:

public void onItemClick(AdapterView<?> adapterView, View view, int postion,
long index) {
// Get MAC adress matching the last 17 characters of the TextView
String info = ((TextView) view).getText().toString(); // HERE IS THE ISSUE
String address = info.substring(info.length() - 17);
Intent intent = new Intent();
intent.putExtra(EXTRA_DEVICE_ADDRESS, address);
setResult(Activity.RESULT_OK, intent);
