将 android 与 google play 服务集成得到“java.lang.IllegalStateException”

Question

我尝试将 google play 服务与我的 unity android 游戏集成。登录 google play 服务后，DDMS 中出现以下日志消息，应用程序崩溃。

我不知道什么是“java.lang.IllegalStateException: No AppStateClient。你在设置时请求过吗？”意味着为。谢谢。

Answer 1

您需要添加APPSTATE客户端，如下图：

//should be called on your application start 
//best practice to call it only once. Any way other calls will be ignored by the plugin.
//if you want to use only Game service (Leader-boards, achievements) use GooglePlayConnection.CLIENT_GAMES
//if you want to use only Google Cloud service use GooglePlayConnection.CLIENT_APPSTATE
//if you want both: GooglePlayConnection.CLIENT_GAMES | GooglePlayConnection.CLIENT_APPSTATE
//and if you whant to get avaliable permissions for your app use: GooglePlayConnection.CLIENT_ALL

GooglePlayConnection.instance.start (GooglePlayConnection.CLIENT_GAMES | GooglePlayConnection.CLIENT_APPSTATE );
