svn上面的最新代码支持databinding了嘛？上面的错误是databinding编译失效，导致home插件里面丢失。在devSample项目里面只看见了small-databinding项目，没有看到在buildsrc里面怎么处理的。。

最新的代码是支持dataBinding的。我试过DevSample运行正常。

原理：

  • AppPlugin#hookDataBinding 将插件的 DataBinding 包名修改为插件包名
  • HostPlugin#hookDataBinding 根据插件包名，分发 DataBinding 对应方法到插件

最新下载的sample工程编译和安装OK，运行时也是报同样的错误：InstantiationException: Unable to instantiate fragment
没看出这个与databinding有关系。

宿主里面的home插件MainFragment 类不存在，代码中添加了混淆的，不知道什么原因造成的，用的AS 3.0。

造成子插件某些class文件资源找不到，是由于该插件使用了databinding，作者在AppPlugin中对databinding进行了处理，如上图。

image
上图代码删除了与项目不相干的文件，但是在window系统中文件分隔符是"",类unix系统是"/",作者可能用的mac笔记本。上图中获取到的relativePath 的开头永远不会和small.packagePath匹配。最终造成class文件被误删除掉了。

该段代码执行前:

执行后:

最终app\smallLibs下对应apk如下:
