简单集成美团热更新RoBust
地址： https://gitee.com/mirrors/Robust
https://github.com/Meituan-Dianping/Robust
当前版本：0.4.99（目前不支持AGP4.1.0：https://github.com/Meituan-Dianping/Robust/issues/434，可以用0.4.100试试）
项目的build.gradle
dependencies {
classpath 'com.meituan.robust:gradle-plugin:0.4.99'
classpath 'com.meituan.robust:auto-patch-plugin:0.4.99'
}
APP的build.gradle
apply plugin: 'com.android.application'
//apply plugin: 'robust' 打基准包的时候用
apply plugin: 'auto-patch-plugin' 打补丁包的时候用
打基准包
拷贝robust.xml到src同级目录，需要修改的地方：<packname name="hotfixPackage"> <patchPackname name="patchPackname">，里面的值分别对应包名和包名.patch
继承com.meituan.robust.PatchManipulate，实现com.meituan.robust.RobustCallBack，代码放最后，都是从官方demo拿过来的
选一个合适的时机，调用new PatchExecutor(context, new TestPatchManipulate(), new TestRobustCallBack()).start();，加载补丁包
开启混淆，才能生成mapping文件
放开APP的build.gradle中基准包的引用，注释补丁包的引用
gradle --> app --> 找到assembleRelease （这一步需要配置签名信息）
执行成功后，会在build --> outputs --> 下面生成对应的文件，需要检查的有apk文件夹下的release>app-release.apk，mapping文件夹下的release>mapping.txt，robust文件夹下的methodsMap.robust
补丁包
拷贝上面的3个文件到src同级的robust文件夹下
修改代码，有修改的方法用@Modify注解，新增的方法用@Add，Lambda需要在方法内部调用RobustModify.modify()，参考官方文档
放开APP的build.gradle中补丁包的引用，注释基准包的引用，同步
run app，不出意外的话，Build会出错误提示：Cause: auto patch end successfully，出这个提示没问题，表示补丁包生成成功
在src同级的robust文件夹下，可以找到一个patch.jar，就是我们需要的补丁文件了
下发和校验
线上发布的下发和校验，可以灵活处理，主要逻辑在集成PatchManipulate的方法fetchPatchList和verifyPatch里面
理论上，robust实时生效，收到补丁包更新信息之后，下载补丁包到指定目录，调用预先设置的加载补丁包的方法，就OK了，实际运行也OK
检查方法：将patch.jar拷贝到手机根目录下的robust文件夹下，重新运行APP，需要权限
资源地址：https://download.csdn.net/download/qq_24179679/19430486，安装包在资源解压后src的同级robust文件夹下
new PatchExecutor(context, new TestPatchManipulate(), new TestRobustCallBack()).start();
有问题看日志，主要是在RobustCallBack中
