Solution for Android Tutorial Hello Gallery problem

I have spent many hours searching over the internet, looking for documentation that would tell me how to redo this tutorial so that it compiles in one of the android sources, i have 1.1, 1.5, 1.6, 2.0.

All seem to no longer have the android.R.styleable available in them, even though it is still in the API, (http://developer.android.com/reference/android/R.styleable.html)

Also the method obtainStyledAttributes is defined in API’s but it does not define what you should be sending in.

After some extensive searching i found a little site called stackoverflow, where someone was so kind to tell me that the 2 lines in question (shown below) can actually be omitted and the program will run. (http://stackoverflow.com/questions/1717489/android-hello-gallery-tutorial-r-styleable-cannot-be-resolved)

TypedArray a = obtainStyledAttributes(android.R.styleable.Theme);
mGalleryItemBackground = a.getResourceId(android.R.styleable.Theme_galleryItemBackground, 0);

The original tutorial is available here:
