unity sdk -AppLovin MAX 广告聚合平台接入+Firebase统计

unity版本：2019.4.40f1

Android Studio ：4.2.1

sdk版本：5.4.6

max对应unity的官方文档：

MAX Mediation Documentationhttps://dash.applovin.com/documentation/mediation/unity/getting-started/integration

1、阅读官方文档下载sdk 全部导入

2、集成器设置

a、集成max SDK 的更新

b、其他中介平台组加入（我这边加入了 google admob 和Mintegral和Pangle 三个中介平台）

c、Applovin key 添加，其他部分根据需求一般保持不变

d、Android 配置设置

3、Firebase接入

Firebase接入文档https://mp.csdn.net/mp_blog/creation/editor/126500929

按以上文档接入，需要注意以上已经接入了google admob的sdk，所以Firebase sdk里面的google部分会冲突，所以冲突部分不需要导入

设置完所有平台和其他插件后Force Resolve 下，就会下载所需的.arr文件

例如：

5、打包发布

由于unity2019，自带版本的gradle较低，跟sdk有冲突（需要升级gradle）

unity中会显示类似这些报错：

Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.

See https://docs.gradle.org/5.1.1/userguide/command_line_interface.html#sec:command_line_warnings

android studio 中显示如下的错误：
