这是我的问题，用户需要上传个人资料图片，但我无法运行应用程序而不会出现任何错误，在logcat中我得到 NetworkOnMainThreadException 所以试图解决它的实现一个线程，但现在任何其他方法都无法访问该变量，我需要该值将其保存在我的数据库中。
我已经读过我需要使用Asysntask但我不知道该怎么做，请提前谢谢
这是我的代码：
public class edit_profile_activity extends AppCompatActivity

private static int RESULT_LOAD_IMG = 1;

super.onCreate(savedInstanceState);

由于Android不允许主（UI）线程上的网络com，您可以扩展AsyncTask以支持文件上传到Cloudinary。
然后，从onPostExecute处理上传响应（在您的数据库中存储信息，更新UI等）。
一个基本的例子 -
class UploadTask extends AsyncTask<String, String, Map<String, String>> {
private Exception exception;
protected Map<String, String> doInBackground(String... params) {
Map response = ObjectUtils.asMap();
try{
response = cloudinary.uploader().upload(<Image file>,
ObjectUtils.asMap("resource_type", "image",
"public_id", <"somePublicId">));
}catch (IOException e){
System.out.println(e.getMessage());
}
return response;
}
protected void onPostExecute(Map<String, String> response) {
// TODO: handle the response
}
}

以下是AsyncTask的一个示例：
private Player player;
private void connect_to_server() {
AsyncTask.execute(new Runnable() {
@Override
public void run() {
player = new Player();
player.start();
}
});
}
假设Player类内部有一些网络操作。
