4 错误 - 错误：包 com.google.android.gms.appstate ETC

Question

我对此很陌生，如果有人愿意为我真正愚蠢地解决这个问题，我会很高兴。我不断收到这 4 个错误，这非常令人沮丧。

我目前在 Mac 上使用 Android Studio。当我尝试创建构建并尝试在线搜索此问题时会弹出这些错误，但这就是我找到的 LINK 并且仍然没有帮助。

/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.

这不允许我创建任何构建

Answer 1

看来：

1. com.google.android.gms.appstate 包未找到。您尚未将其链接到您的程序。
2. AppStateManager 无法识别，但这是第一个错误的结果。
