These are the words of Jake Wharton, a developer who has built a library (and not only) that allows android developers to avoid compatibility problems across android versions and that greatly simplifies apps design development. Some months ago I have tried this free product but I was disappointed by a bug related to CursorLoader that stopped with crash my app. Then I started to develop a more simply and proprietary library that I have used in WhatsUp for the LifeParticipation team, in which I’m still a member.
In the last months Wharton has continued to fix, expand and complete his work and in these days I’m building a new app that is based on this great project. At the moment I haven’t found any bug and I have found a great and simply support for plugins (as his ViewPagerIndicator) that allows me to build an app without considering some development problems.
If you’re curious, I invite you to spend some of your time trying ActionBarSherlock.
I think this one of the more important project that helps you during your android development experience.
