我在同时遇到两个网络操作的问题。
这是我正在处理的代码：
public void onClick(View v) {

switch(v.getId()){

openGalleryAudio();
break;
case R.id.btUpload:

基本上，我的应用程序将音频文件上传到服务器，并将文件的元数据插入数据库服务器。但是我收到了一个错误。请在下面看到我的logcat错误：

注意：
保存音频文件的元数据是有效的，但音频文件的上传似乎无法正常工作。
有什么想法吗？我遇到了这个问题。我真的需要你的帮助。感谢。
答案 0 :(得分：1)
从我看到的内容，您对UI进行了2次更改， 您可以关闭对话框或关闭活动。
我认为您正在关闭活动，然后尝试使用对话框执行某些操作。 因此，你有一个泄露的窗户，因为没有活动。
