Android screen resolution question

Hi all.
Question about scale, it does not work, I do this:
1 Change the file following the pull request https://github.com/ChristianFischer/cocos2d-x/commit/b25b493e337ea50e0c5447dc9ffd5d3536b7440b:
cocos2dx/platform/android/CCEGLView_android.cpp
cocos2dx/platform/android/CCEGLView_android.h
cocos2dx/platform/android/CCFileUtils_android.cpp Two.
2. In file HelloWorld\android\jni\helloworld\main.cpp prescribes view-> create (320,480, true)
3. No changes after the launch of the various devices that do not scale well, that I missed?

We didn’t think his pull request was a correct solution, so we didn’t merge his pull request.
What’s your requirement?

I just wanted to know, who tried this solution. Does this method really works?
