需求：
unity将游戏导出android工程之后，打成aar包的工具
第一种：
高版本的unity导出的android工程是android studio版的，那么打成aar的流程就是
1.build.gradle文件中把apply plugin: 'com.android.application'改成apply plugin: 'com.android.library'
2.build.gradle文件中buildToolsVersion改为25.0.2
3.注释掉applicationId这一行
4.清单文件AndroidManifest.xml中启动Activity，一般是UnityPlayerActiity，标签内全部删除
5.src.java下类UnityPlayerActiity共三个都删除
6.然后在主目录下执行命令gradlew.bat assembleDebug生成aar
把上述流程做成java自动的工具，代码如下

jar包打成可运行程序参考android studio打可执行jar包
