我想使用Unity在Android移动应用中实现排行榜。
我正在使用:
Unity 2018.2.18f1(Mac)
Java开发工具包(jdk.1.8.0_191)
Google Play游戏插件0.9.57 [当前版本1.1.2019]
Google Play服务已成功激活(应用内购买可以正常工作),但是在尝试使排行榜功能正常工作时,我一直收到此错误:
java.lang.ClassNotFoundException: com.google.games.bridge.TokenFragment
进一步(为了清楚起见:我用XXXX替换了应用名称):
Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.games.bridge.TokenFragment" on path: DexPathList[[zip file "/data/app/com.NGDD.XXXX-1/base.apk"],nativeLibraryDirectories=[/data/app/com.NGDD.XXXX-1/lib/arm, /data/app/com.NGDD.XXXX
和
2019-01-01 17:48:52.784 15145-15145/com.NGDD.XXXX W/System: ClassLoader referenced unknown path: /system/framework/QPerformance.jar
2019-01-01 17:48:52.785 15145-15145/com.NGDD.XXXX E/BoostFramework: BoostFramework() : Exception_1 = java.lang.ClassNotFoundException: Didn't find class "com.qualcomm.qti.Performance" on path: DexPathList[[],nativeLibraryDirectories=[/system/lib, /vendor/lib]]
...这导致:
*** [Play Games Plugin DLL] 01/01/19 17:51:50 +01:00 ERROR: ShowLeaderboardUI can only be called after authentication.
我试图检查SHA-1证书,但不知道如何从Mac上的Google Play控制台检查和匹配Keystore和SHA-1。
这是场景在Unity中加载时正在执行的代码:
void ActivateGooglePlayServices()
{
PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder().RequestIdToken().Build();
PlayGamesPlatform.InitializeInstance(config);
PlayGamesPlatform.Activate();
LoginToGooglePlay();
}
public void LoginToGooglePlay()
{
((PlayGamesPlatform)Social.Active).localUser.Authenticate((bool success) =>
{
if (success)
{
Debug.Log("!!! Login Success !!!");
}
else
{
Debug.Log("!!! login failed !!! ");
}
});
}
排行榜调用如下:
public void ShowLeaderBoard()
{
// this didn't work at all: --> ((PlayGamesPlatform)Social.Active).ShowLeaderboardUI (leaderboard_ID);
// The following line throws: *** [Play Games Plugin DLL] 01/01/19 17:51:50 +01:00 ERROR: ShowLeaderboardUI can only be called after authentication.
Social.ShowLeaderboardUI();
}
带有NullReferenceException错误的整个部分,我无法理解:

预期的结果是调用ShowLeaderBoard()时会弹出Google页首横幅用户界面。
答案 0 :(得分:1)
好几天我都遇到过同样的问题,只是想通了。
如果项目路径名中包含特殊字符,则它将无法解析。
我的项目有一个带有“!”的文件夹。在路径名中,我只是简单地重命名了该文件夹,并确保不要使用空格或特殊字符,它现在可以使用!
我希望这也能解决您的问题!
