Android :: Obtaining Exact SDK Source

I was hoping someone could give me instructions to obtain the *exact *source code for the current SDK. What I have so far is as discussed here; http://androidforums.com/android-developers/1045-source-code-android- By using commands such as; repo init -u git://android . git . kernel .org/platform/manifest.git -b android-sdk-1.5_r3 jar cvf ../android-src.jar -C core/java . etc. my issue is that the source is still inconsistent, some extra methods are available and some are not. For example, I want to make a progress bar with two sliders (To select a range) but the version of Progress bar I have; http:// android .git.kernel.org/?=platform/frameworks /base.git;a=blob ;.http://android .git.kernel .org/?p=platform/ frameworks /base.git;a=blob;> I cannot mimic (as an initial implementation), despite using the same package and extending View I do not have access to 'mMinWidth' for example. In addition the progress bar uses methods of the class StateList Drawable which are not available in this SDK (e.g. getStateSet(int i)). It's obvious that there's an inconsistency between the source I have and that which was compiled into the android SDK but I don't know why given my GIT repo commands. Can someone link to the version of ProgressBar which was shipped with android-sdk-1.5_r3? Has anyone managed to get the branch which maps directly to this release? This might well be due my inexperience with Git, please let me know if anyone has this set up correctly and I will try again. I seem, in all honesty, to have the head revision still.
