After some research around JSON libraries I reached conclusion that Jackson would be the first choice, both because it is much more used then Gson and it seems to have performance edge over Gson as well. Unfortunately though, adding just the core and the databind jars, without using ProGuard inflates the size of the final APK by a whooping 600Kb.

There is a pretty way way to get the Git commits between versions which can be used to build the change set log.
Below are the basic commands that should give you just that. But these commands are even more useful than this. This is almost too easy, this is why I call it wizardry :)
The only requirement is that you somehow know what is the commit of the latest release you did (if that's where you want to start your change set)
To find a specific commit (if you had a meaningful commit message)
git log --pretty=format:"%h - %an, %ar : %s" | grep "RELEASE: X.X.X"
or you can just use tag (if you have tagged the commit that preceded the release) and see where it points to or any other way you use to find the latest release commit where you want to start.
Once you found it, it's as easy as for example:
git log --pretty=format:"%h - %an, %ar : %s" b9c28fc..

A short list of most useful Git commands to work with git tags. These should cover 90% of your needs.
### TAGS
#create tag (annotated = with extra meta information)
git tag -a ver1.4 -m 'my version 1.4'
#list tags
git tag
#delete tag
git tag -d XXX
#delete remote tag
#You just need to push an 'empty' reference to the remote tag name:
git push origin :tagname
#push tags to remote
#specific tag:
git push origin v1.5
#all tags:
git push origin --tags

I hate facebook Engineers. Yes, you heard me right. I hate them. Well, maybe not them but their hairy pointy managers and bosses who... wait a second, isn't facebook "famous" for being all staffed with engineers? So yes, I hate facebook Engineers
Now you will say but why, they are mostly smart guys and facebook is so spectafackamazing. WHY?!?... Well, for one their mobile SDK suck. Full of bugs, crashes and other pleasantries. I did at least 5 updates solely because there was some problem with Facebook and the most interesting part of that is that the updates were required after some change that was made that broke things. The integration is working 100% for 4 month and then one day goes KABOOM.
They are all warm and fuzzy now, trying to get to mobile developers, well you got under my skin for sure guys. But even now, when all news are raving how they redesigned and updated and what not their portals for mobile developers who use their SDK to integrate with them they still have problems. Just couple days ago when they started pushing into every possible media hole the news that they got the new SDK and blahblahblah
reserved but intrigued (can it be that FINALLY they got the SDK to a decent shape?!?) off I went to check it. For a long time I have been using the latest clone of their github repository and I decided to see whether it is different from the repository - indeed it was. Ok, I thought I should use the SDK and off I went to integrate it within my app just to see that it crashes 100% of the time with SSL error. Damn I though and went back to github's repo which not surprisingly did not have this problem.
That's not funny.... It never was. Seriously - pull your shit together! I don't need and don't want to spend 2–5 hours every few months to work around yet another problem you have introduced.
To remove inactive ports:
sudo port uninstall inactive
To remove downloaded distfiles with:
sudo port clean --all installed
To remove orphaned (not referenced and not anymore used ports) you can use an external tool port_cutleaves
First install the tool using MacPorts
sudo port install port_cutleaves
Then run it
sudo port_cutleaves

The following crash was cripping into the reports. There is no usage of the webview directly, but there is a usage of the webview and thus related stuff in the ads.
java.lang.NullPointerException
at android.webkit.WebViewDatabase.getCacheTotalSize(WebViewDatabase.java:815)
at android.webkit.CacheManager.trimCacheIfNeeded(CacheManager.java:548)
at android.webkit.WebViewWorker.handleMessage(WebViewWorker.java:190)
at android.os.Handler.dispatchMessage(Handler.java:99)
at android.os.Looper.loop(Looper.java:123)
at android.os.HandlerThread.run(HandlerThread.java:60)
The problem is the following code:
long getCacheTotalSize() {
long size = 0;
Cursor cursor = null;
final String query = "SELECT SUM(contentlength) as sum FROM cache";
try {
cursor = mCacheDatabase.rawQuery(query, null);
if (cursor.moveToFirst()) {
size = cursor.getLong(0);
}
} catch (IllegalStateException e) {
Log.e(LOGTAG, "getCacheTotalSize", e);
} finally {
if (cursor != null)
cursor.close();
}
return size;
}
The NullPointerException that happens should in general not happen but sometimes the storage gets corrupted and then the cache database is null when it is called and it crashes.
The fix would be to check for this problem and then only use WebView and/or call the ads if there is no problem with the WebViewDatabase
WebViewDatabase webViewDB = WebViewDatabase.getInstance(this);
if (webViewDB != null) {
// do what you wanted to do with the WebView
}
