我把这个代码注册一个reciever检查互联网连接Availability.And我用下面的线把它放在Manifiest文件。但当尝试这个代码，我得到以下错误。我用这个代码schaeck互联网连接之前，我送一些data.I DONOT知道如何在manifest文件中注册该

02-13 16:59:31.109: E/AndroidRuntime(28123): java.lang.RuntimeException: Unable to instantiate receiver org.apache.cordova.example.NetworkConnectivityListener: java.lang.ClassCastException: org.apache.cordova.example.NetworkConnectivityListener cannot be cast to android.content.BroadcastReceiver 

Answer 1

由于NetworkConnectivityListener不是广播接收器的孩子，这就是为什么错误弹出的高达 SOLUTION： 清单文件注册听众如下，

<receiver android:name="org.apache.cordova.example.NetworkConnectivityListener$ConnectivityBroadcastReceiver" /> 

ALTERNATE：

注册接收器的NetworkConnectivityListener内本身作为你在Manifest中删除了条目。

Answer 2

从广播接收器延长NetworkConnectivityListener，你要注册普通班，而不是广播接收器类
