android插件化开发--修改携程插件开发支持provider

在用携程做插件开发的过程中遇到provider不能加载的问题，不需要再androidmanifest.xml中预先配置。

在framework\storage\BundleArchiveRevision.java下修改如下方法：

public void optDexFile() throws Exception {    List<File> files = new ArrayList<File>();    files.add(this.bundleFile);    BundlePathLoader.installBundleDexs(RuntimeArgs.androidApplication.getClassLoader(), revisionDir, files, false);    installProviders(RuntimeArgs.androidApplication, bundleFile);}
