AsyncTask postExecute崩溃

使用asyntask查询表中的所有数据并将其放入数组List中，然后将其发送到服务器时，出现问题。我能够将数据成功发送到服务器。但是应用程序崩溃的异步服务器的postexecute给出以下错误：AsyncTask postExecute崩溃

(W/System.err﹕ org.json.JSONException: Value ["com[email protected]41b06d18","com[email protected]41b070b8"] of type org.json.JSONArray cannot be converted to JSONObject)..

什么可能是问题？我在哪里错了。有人请帮助...非常感谢。

可能是什么问题？您正在以错误的方式构建某种JSON数据 - 这就是例外情况。如果您可以发布堆栈跟踪并指出引发异常的位置 – Antoniossss

尊敬的团队，......我收到来自服务器的响应，作为JSON响应。这是我收到的响应：----响应：{“ ResponseCode “：” 00" ， “ResponseMsg”： “成功”}。当我尝试从SQLite中查询所有数据并将其放入一个ListArray并一次发送通过asyncTask时，会发生此问题.......但是，当我只查询一个项目并发送时，不会发生此错误 – Turbo

当它到达JSONObject时发生错误jsonBreaker = new JSONObject（result）;我希望这些信息对您有所帮助。我真的被困在这里。 – Turbo

如果你想basta stacktrace和opoint其中rxception被抛出会更容易。反正

你result可能是和JSONArray不是JSONObject所以这

JSONObject jsonBreaker = new JSONObject(result);

导致异常。构建JSONArray保证JSONObject和这个肩膀没事（这是我的盲猜cuz没有可行的信息在这里）

非常感谢Antoniossss。它工作。我设法改变JSONObject jsonBreaker =新的JSONObject（result）;到JSONArray jsonBreaker = new JSONArray（result）; success = String.valueOf（jsonBreaker.getString（0））; message = String.valueOf（jsonBreaker.getString（1））;现在错误消失了。非常感谢您的解决方案 – Turbo

如果这是正确的解决方案，请接受答案（在左侧打勾）并正确向上投票（向左箭头） – Antoniossss
