将工程A做成android library project。
设置工程A,右键->Properties->Android,将Is library项选中,然后Apply。设置工程B,右键->Properties->Android,在Library中,点击Add按钮,将A工程加入,然后Apply。此时在B中就引入了A中的资源和代码,这些资源和代码都可以直接调用。需要注意的是,因为A已经不再是一个完整的Android应用,而是一个类库工程,所以有一些内容还需要在B中配置一下。比如A中有lib库引用,则B中也要加入该lib库;比如A中的AndroidManifest.xml文件的内容,在B的AndroidManifest.xml文件中也要相应加上。。。
