Android Studio writes aar to Unity notes

This blog is to make a work note for later viewing.

common mistakes

1. BuildConfig duplicate error

Add in the android tag in build.gradle

 //这个配置是为了防止 导出包时 与Unity 包的buildConfig 文件发生冲突导致打apk 失败，添加后android studio 导出的aar 包不会包含 buildConfig文件
    buildFeatures{
        buildConfig = false
    }

2. UnityPlayerActivity.java problem

Because the new version of unity classes.jar does not contain UnityPlayerActicity.java, we need to go to the installation directory to copy <font size=4>C:\Program Files\Unity\Hub\Editor\2020.3.33f1\Editor\Data\PlaybackEngines\AndroidPlayer\ Source\com\unity3d\player</font>

 The above solution is to delete UnityPlayerActivity.java in the packaged aar

 3. 编译出现 Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8.

 Add a directory in gradle.prooerties and fill in the corresponding installation directory

4. Modify the compiled aar name and add the following code to the android tag of build.gradle
