iapp利用java判断手机是否有网络

代码

javanew(ct,"android.content.Context")
javags(cs,ct,"android.content.Context","CONNECTIVITY_SERVICE")
java(cm,activity,"android.app.Activity.getSystemService","String",cs)
java(nif,cm,"android.net.ConnectivityManager.getActiveNetworkInfo")
f(nif != null)
{
java(ss.rnink,nif,"android.net.NetworkInfo.isAvailable")
tw("有网络")
}
else
{
ss rnink = false
tw("无网络")
}

本源码比hs获取网页判断是否有网络更加快速。
