仅导入了Firebase Database，求解决方法。

解决方案 #

1. 彻底清理并重新导入Firebase包 #

• 删除Assets目录下的Firebase、Google文件夹
• 打开Package Manager，移除所有Firebase相关包
• 下载与当前Unity版本兼容的Firebase Database包，手动导入到项目中
• 导入完成后重启Unity，再进行后续配置

2. 修复Jar Resolver依赖问题 #

• 打开Package Manager，搜索并安装Google Play Resolver（若未安装）
• 进入Assets > External Dependency Manager > Android Resolver > Settings，勾选Enable Gradle Daemon和Enable Jetifier
• 勾选Project Settings > Player > Publishing Settings > Build下的Custom Main Gradle Template，打开模板文件，在dependencies块中添加对应版本的依赖（版本号需与Firebase包匹配）：

  implementation 'com.google.firebase:firebase-database:20.2.2'
  implementation 'com.google.firebase:firebase-app:21.1.0'
  

3. 检查Native库配置 #

• 确认Firebase的Native库（如FirebaseCppApp-10_2_0.so）存在于Assets/Plugins/Android/libs/arm64-v8a和armeabi-v7a目录下
• 在Player Settings > Other Settings > Configuration中，设置Scripting Backend为IL2CPP，Target Architectures勾选arm64和armeabi-v7a
• 选中.so文件，在Inspector面板确认Platform为Android，对应CPU架构设置为Compatible with

4. 强制Resolve的替代方案 #

• 删除Library目录，重启Unity后执行Assets > External Dependency Manager > Android Resolver > Force Resolve
• 若Resolve仍失败，手动下载对应版本的firebase-app-unity.aar、`firebase-d
