【问题描述】：
我已经尝试了所有方法，请任何人帮助我处理此代码。它给出了错误解析 org.json.jsonexception 值 br 类型 java.lang.String 无法转换为 JSONOobject 错误。除了这个错误 logcat 什么都没有显示。我认为问题出在 Post Login() 方法中，但我无法弄清楚问题所在。当我单击发送按钮时，问题就来了。问题可能出在发送按钮和 PostLogin 方法中。我是新的堆栈溢出，所以如果出现问题，请合作。我已经失去了 3 天的时间，但看不出真正的问题是什么。请任何人解决它。是紧急状况。

【问题讨论】：
-
发布你的日志。根据这个错误
java.lang.String cannot be converted to JSONOobject error它说你正在将 String 转换为JSONObject。 -
你能发布json响应吗？
-
logcat 是空白的.. 上面的错误也会在 toast 中弹出。 logcat 里面什么都没有
-
请发布您从服务器获得的响应。

请发布您从服务器获得的响应。正如@Aniruddha 所说
