我尝试一个在线教程进行注册并登录，我将执行所有操作。但我的问题是当我填写表单并连接到网络后尝试按下寄存器时，它会中止显示错误的应用程序（不幸learn2crackLogin已停止）Android应用程序不会连接到本地主机（Wempserver）
应用程序的名称是learn2crachLogin。一个我主持的WWW数据库文件中wempserver名learn2crack_login_api
我试着回答slimier问题下，但它并没有解决我的问题
我不知道什么截图你需要所以请让我知道..
这里是我的清单

它给出了哪个错误？发布您的logcat输出 – Pelocho
@ Dr.Pelocho对不起，我刚刚做了 – NuhaAbd
'由java.lang.SecurityException产生：ConnectivityService：无论用户10064还是当前进程都有android.permission.ACCESS_NETWORK_STATE'现在请解释这个不错的部分错误信息你不了解。 – csmckelvey
