使用 Android 13 设备、位置插件 ^4.4.0、firebase_messaging ^14.1.2

Answer 1

此问题源自位置插件，该插件引用旧版本的 google play 服务插件。

要解决此问题，您需要更新位置包中“com.google.android.gms:play-services-location”的版本

更改“api 'com.google.android.gms:play-services-location:16+'”的依赖关系

到“api 'com.google.android.gms:play-services-location:21.0.1'”

最后，保存并重建项目
