谷歌搜索的問題沒有取得什麼結果。似乎有一個similar issue with the Unity plugin和this blog isn't helping much。

爲什麼會發生此錯誤？有人遇到過這種情況麼？

Answer 1

這些錯誤是由不屬於您的應用程序的google-play-services jar文件引起的。這些步驟佈局上https://developers.google.com/games/services/cpp/gettingStartedAndroid 檢查事項：

1. 您項目包括谷歌，播放services.jar和Android的支持 - v4.jar文件（它們被包含在APK文件）。
2. 它是庫的最新版本（至少22版，但最新版是首選）。您可以使用SDK管理器下載最新版本。

Answer 2

萬一有人遇到這個問題，但沒有解決問題了，這裏是我如何固定我的：我改變我的Proguard的配置，因此不會從com.google.android包裝帶任何類。

即： 從-keep public class com.google.android.gms.* { public *; }到-keep public class com.google.android.gms.** { public *; }

您可能還需要激活multiDex在build.gradle文件，下面幾行： buildTypes { yourBuildType_Eg_release { multiDexEnabled true dexOptions { preDexLibraries false incremental true // that's a big heap! javaMaxHeapSize "4g" } } }
