Android 3G Connection

Question

When i am using wifi network all is working fine ,,but when i turn off all network(Not Airplance mode) and turn on 3G HotSpot then my application is not even detecting connection.So web service shwoing timeout errors.

ConnectivityManager cm = (ConnectivityManager)getSystemService
(Context.CONNECTIVITY_SERVICE);;
boolean 3GCon=cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).isConnected()

This returning always false

Answer 1

为什么不尝试使用isAvailable（）而不是isConnected（）？

Answer 2

很难给出一个确切的答案，说明它为什么不适合你，但作为一个开始，我建议你看一下这个例子，比如这个ConnectivityManagerTestActivity ，并将它与你自己的代码进行比较。
