Firebase for Unity示例應用程序崩潰：無法找到'com.google.android.gms.common.api.PendingResult'類'

Question

我試圖運行適用於Unity的Firebase示例身份驗證應用程序（從here）， 但該應用程序在初始化過程中崩潰。

這裏的崩潰日誌：

它看起來像你錯過了播放服務基地AAR包含PendingResult，這可能意味着你錯過了其他Android依賴的SDK爲好。

您應該看到一個AAR就像在你的資產文件夾中的項目下面，當你選擇Android作爲目標平臺： *資產/插件/ Android的/播放服務鹼基10.0.1.aar

這包含PendingResult類...

$ unzip Plugins/Android/play-services-base-10.0.1.aar classes.jar 
    Archive: Plugins/Android/play-services-base-10.0.1.aar 
    inflating: classes.jar  
$ unzip -l classes.jar | grep /PendingResult\.class 
    1762 11-22-16 22:25 com/google/android/gms/common/api/PendingResult.class 

有可能是一對夫婦的事情，可能是錯在你的項目：

• 你有Android的RESOLV呃禁用（通過資產 - >播放服務解析器 - > Android解析器 - >設置菜單項啓用它）
• 您的項目中有Android AARs的混合不匹配。 刪除Assets/Plugins/Android/下的所有.aars，並允許Android Resolver提取最新的設置。
