android文档里有如下内容。
1 To enable ProGuard so that it runs as part of an Ant or Eclipse build, set the proguard.config property in the <project_root>/default.properties file. The path can be an absolute path or a path relative to the project's root.
在default.properties添加
1 proguard.config=proguard.cfg
即可实现proguard混淆。
