这个问题在这里已有答案：
我正在尝试在重新建立网络连接后将一些信息上传到服务器。但是一旦我到达这一点，应用程序的流程就会中断并停止上传过程，我会得到标题上显示的异常。
应该怎么做：启动线程，上传文件并继续而不破坏流程。
发生了什么：进程尝试启动，中断并且不上传任何文件。
public static void responseJson(JSONObject response) throws JSONException {
try {
JSONObject jsonResponse = response.getJSONObject("quote");
int idServer = jsonResponse.getInt("id");
dbAgenda.updateAgenda(idServer, id_local);
((Activity)context).runOnUiThread(new Runnable() {
@Override
public void run() {
submitAgenda();
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
这是我得到的错误：

我相信最后一部分是主要的culprid，但我无法弄清楚如何解决它。
这是一个BroadcastReceiver？你不能把ReceiverRestrictedContext施放到Activity这一行 - > ((Activity)context)。这可能是this question here的重复。
