eclipse 跟 android studio 完全可以用同一套代码,使android studio 的代码结构可以跟eclipse一样

 sourceSets {

        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
            jniLibs.srcDirs = ["libs"]
        }


        // Move the tests to tests/java, tests/res, etc…
        instrumentTest.setRoot('tests')


        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, …
        // This moves them out of them default location under src/<type>/… which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        //debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}
