接着android：一步步实现插件化与热更新（一）的内容继续下面的操作
六、插件化更新
-
修改代码
我修改的是app.chat中FromHomeActivity
在参数传递过来的时候，弹个吐司： UIUtils.showToast("name=" + name + ",age=" + age); -
记得修改版本号：
versionCode 2 1——>2 versionName "1.1" 1.0->1.1 注意你修改的哪个插件修改哪个插件的版本即可，不是宿主app模块，我这里修改的是app.chat - 两步：buildLib->buildBundle
-
查找so，在你的宿主模块中
-
部署服务器，我直接在我的电脑上部署一个tomcat
-
服务器的bundle.json
{ "manifest": { "bundles": [ { "pkg": "tsou.cn.lib.data", "uri": "lib.data" }, { "pkg": "tsou.cn.lib.utils", "uri": "lib.utils" }, { "pkg": "tsou.cn.lib.style", "uri": "lib.style" }, { "pkg": "tsou.cn.lib.layout", "uri": "lib.layout" }, { "pkg": "tsou.cn.lib.icon", "uri": "lib.icon" }, { "pkg": "tsou.cn.app.home", "uri": "home" }, { "pkg": "tsou.cn.app.chat", "rules": { "FromHomeActivity": "tsou.cn.app.chat.activity.FromHomeActivity" }, "uri": "chat" }, { "pkg": "tsou.cn.app.recom", "uri": "recom" }, { "pkg": "tsou.cn.app.me", "uri": "me" } ], "version": "1.0.0" }, "updates": [ { "pkg": "tsou.cn.app.chat", "url": "http://192.168.19.125:8080/json/libtsou_cn_app_chat.so" } ] } - 实现插件化更新

}到此你就可以使用small进行插件化开发了........
