我对GooglePlayService（com.google.android.gms）有疑问 是否可以在没有GooglePlayService的情况下使用Youtube Data API？
我的设备未安装GooglePlayService和GooglePlayStore。 但我必须使用Youtube Data API。
现在使用Youtube Data API，显示错误对话框
'此应用无法在没有Google Play服务的情况下运行，而这些服务在手机中无法使用
请回复我的问题。 感谢。

使用此片段在您的应用中显示Youtube视频。这个片段类允许： -

使用此方法检查连接状态： -
public static boolean isConnected(Context context) {
NetworkInfo info = Connectivity.getNetworkInfo(context);
return (info != null && info.isConnected());
}
这是用于显示离线通知的对话框布局
