我搜索了它，但我不知道在我的代码中多少使用了一个实体。你能告诉我哪些部分需要修复这些错误吗？我尝试从JSONObject传递值，我将从我的php端到下一个活动。

很抱歉，我问你很多事情，但你能告诉我线程是否可以访问或在下一个活动中运行？ （当我点击按钮转到下一个活动时，我会收到这些错误。它不会转到下一个活动，只是保持当前活动。）
我添加了HttpResponse responseTwo = response;
一些错误发生了变化

答案 0 :(得分：0)
为了简单快速的结果，我建议Android Asynchronous Http Client
例如：添加此依赖项
dependencies {
compile 'com.loopj.android:android-async-http:1.4.8'
}
并且
public void uploadToServer(){
AsyncHttpClient asyncHttpClient = new AsyncHttpClient();
RequestParams requestParams = new RequestParams();
imageData = Base64.encodeToString(img, Base64.DEFAULT);
String xDat = xPoint.toString();
String yDat = yPoint.toString();
requestParams.put("imageData" , imageData);
requestParams.put("xData" , xDat);
requestParams.put("yData" , yDat);
asyncHttpClient.post(urlServer , requestParams , new JsonHttpResponseHandler(){
@Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
//Call back if your response is JSONObject
}
@Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
//Failure callback
}
@Override
public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
//Call back if your response is JSONArray
}
});
}
