我正在使用外部依赖管理器 1.2.115、Gradle 5.1，我正确设置了JAVA_HOME路径，并且最近刚刚将我的 Google Play 游戏插件统一更新为 GooglePlayGamesPlugin-0.10.09。 所以我尝试这样做：外部依赖管理器>资产> Android 解析器>强制解析
我明白了..

我到处搜索和搜索，几乎尝试了我登陆的任何页面上的所有内容，包括：https://github.com/firebase/quickstart-unity/issues/359 这与我的问题有关，但没有真正的答案："解决方案失败！您的应用程序将无法运行，有关详细信息，请参阅日志">
帮助将不胜感激。
Android上的 Unity 中 Firebase 的依赖项可以通过 Gradle 下拉，就像 Android 项目一样。这意味着您需要确保自己有互联网连接，并且防火墙不会阻止这些文件的下载。
添加mainTemplate.gradle文件并推送该下载/解析步骤可能很方便，直到您进行Android构建。否则，应在有权访问这些文件时运行 jar 解析程序，并确保保存Assets/Plugins/Android/以便在脱机时使用。
如果您已连接到互联网并且认为您不应该被任何东西阻止，请务必尝试使用 gradle 集成并尝试导出您的构建并使用 Android Studio 打开它。如果它与JAVA_HOME，它可以以这种方式工作(然后提出问题或联系支持人员可以帮助实现真正的解决方法(。
让我知道这是否有帮助！
