4錯誤 - 錯誤：包com.google.android.gms.appstate等ETC

Question

我對此很新，並希望如果有人能真正愚蠢的這下來我。我一直在不斷收到這4個錯誤，而且相當令人沮喪。

我目前在Mac上使用Android Studio。當我嘗試創建構建時彈出這些錯誤，並且我嘗試在線搜索此問題，但這是我發現的LINK，仍然沒有幫助。

/Users/name/Desktop/test/game/BaseGameUtils/src/main/java/com/google/example/games/basegameutils/GameHelper.java 

Error:(32, 39) error: package com.google.android.gms.appstate does not exist 
Error:(293, 28) error: cannot find symbol variable AppStateManager 
Error:(294, 30) error: cannot find symbol variable AppStateManager 
Note: Some input files use or override a deprecated API. 
Note: Recompile with -Xlint:deprecation for details. Error:Execution failed for task ':BaseGameUtils:compileDebugJava'. 
> Compilation failed; see the compiler error output for details. 

這並不讓我產生任何構建

看來：

1. 包com.google.android.gms.appstate不找到。您尚未將其鏈接到您的程序。
2. AppStateManager無法識別，但這是第一個錯誤的後果。
