如何打开，测试是否存在WAP连接以及如何访问它？

public boolean testIfInternetConnectionIsAvailable(Context context)
{
    ConnectivityManager conMng = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo info = conMng.getActiveNetworkInfo();
    if (info == null) return false;
    if (!info.isConnectedOrConnecting()) return false;
    if (!info.isAvailable()) return false;
    return true;    
}
