无法在连接更改时将ReceiverRestrictedContext强制转换为android.app.Activity

我目前正在尝试在建立网络连接后将一些信息上载到服务器。 但是一旦到达这一点，应用程序的流程就中断了，并停止了上传过程，并且出现了标题上显示的异常。

会发生什么：启动线程，上传文件，然后继续执行而不会中断流程。

正在发生的事情：该过程尝试启动，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罪魁祸首，但我不知道如何解决。

答案 0 :(得分：0)

是BroadcastReceiver吗？您无法在此行-> ReceiverRestrictedContext上将Activity投射到((Activity)context)。可能是this question here的副本。
