我的应用程序有问题，我正在获取我的 android 手机的 gps 位置，然后在获得坐标后，我想将该数据传递给我的 web 服务，但我遇到了这个错误，它在 localhost 中运行完美。

这些是我得到的错误：

这是我的课：

    TextView txtLatitude;
    TextView txtLongitude;

    public static String strLat;
    public static String strLong;

您在 中创建一个对话框，onPreExecute但不要在 中将其关闭onPostExecute。

您AysncTask完成并pDialog超出范围（它已被破坏），但窗口仍在屏幕上，因此已泄漏。

您还需要在开始另一个活动或调用finish().

还要添加它，onPause()以便在您的活动被强制到背景时将其关闭并重新显示它，如果您需要，在onResume()

@Override
public void onPause(){

    super.onPause();

    if(pDialog != null){
        pDialog.dismiss();
    }        

    ...

}

基本上，如果您的任务完成或您离开活动，请不要将对话框留在屏幕上。
