我目前使用
Unity版本：2021.3.33f1
JDK版本为：1.8
Gradle 版本为：6.1.1
Firebase 版本: 9.6.0
Google Sign In 版本为： 1.0.1
问题1 ：手机点击登录报错
apk转化成zip，解压，看到/lib/armeabi-v7a包含libnative-googlesignin.so，/lib/arm64-v8a中不存在libnative-googlesignin.so，这就导致手机点击登录报错，找不到native-googlesignin.so
查看GoogleSignIn/Editor/mm2repository/com/google/signin/google-signin-support/1.0.1/google-signin-support-1.0.1.aar文件，解压后发现arm64-v8a不存
所以需要重新构建 Package 在build.gradle中添加修改
问题2 ： firebase关联 google登陆
Firebase 的Authentication选择登陆方法，添加gogole登陆
问题3 ： Error SignInFragment Exception caught! Failed resolution of: Lcom/google/android/gms/common/api/Api$zzf;
修改.gradle文件（这里的问题主要是版本不正确）
版本如下：
dependencies {implementation fileTree(dir: 'libs', include: ['*.jar'])
// Android Resolver Dependencies Startimplementation 'com.google.android.gms:play-services-auth:10+' // Assets/GoogleSignIn/Editor/GoogleSignInDependencies.xml:20implementation 'com.google.android.gms:play-services-base:18.1.0' // Assets/Firebase/Editor/AppDependencies.xml:17implementation 'com.google.firebase:firebase-analytics:21.1.1' // Assets/Firebase/Editor/FirestoreDependencies.xml:15implementation 'com.google.firebase:firebase-analytics-unity:9.6.0' // Assets/Firebase/Editor/AnalyticsDependencies.xml:18implementation 'com.google.firebase:firebase-app-unity:9.6.0' // Assets/Firebase/Editor/AppDependencies.xml:22implementation 'com.google.firebase:firebase-auth:21.0.8' // Assets/Firebase/Editor/AuthDependencies.xml:13implementation 'com.google.firebase:firebase-auth-unity:9.6.0' // Assets/Firebase/Editor/AuthDependencies.xml:20implementation 'com.google.firebase:firebase-common:20.1.2' // Assets/Firebase/Editor/AppDependencies.xml:13implementation 'com.google.firebase:firebase-crashlytics-ndk:18.2.13' // Assets/Firebase/Editor/CrashlyticsDependencies.xml:13implementation 'com.google.firebase:firebase-crashlytics-unity:9.6.0' // Assets/Firebase/Editor/CrashlyticsDependencies.xml:20implementation 'com.google.firebase:firebase-firestore:24.3.1' // Assets/Firebase/Editor/FirestoreDependencies.xml:13implementation 'com.google.firebase:firebase-firestore-unity:9.6.0' // Assets/Firebase/Editor/FirestoreDependencies.xml:20implementation 'com.google.signin:google-signin-support:1+' // Assets/GoogleSignIn/Editor/GoogleSignInDependencies.xml:11
// Android Resolver Dependencies End
**DEPS**}
问题4 ： Attempt to load writable dex file: /data/user/0/com.dialog.soulmaster/cache/app_resources_lib.jar
确保firebase和Google的插件都勾选了Android平台选项
