Android Testerfield失败-带有JSON对象的Android HTTPPost

我对使用HTTP还不熟悉，安卓系统更是如此。我正在尝试/必须验证使用JSON对象通过HTTP Post发送所需信息的登录名

当我运行应用程序时，我使用登录屏幕登录，该屏幕要求将安装添加到访问url、用户名和密码中。我输入这些，点击确认按钮，然后应用程序崩溃，出现一条消息说：“不幸的是，TesterField已经停止。”

我无法破译LOGCAT中识别的内容

有人能告诉我这个（运行时）错误背后的原因吗？

感谢

错误是由于试图在主线程上连接到internet。我使用AsyncTask在后台在另一个线程上执行到internet的连接。
