Okay. That's almost crazy. In my almost 3 years of maintaining our app that was originally written in Eclipse, we never had to face any single issues like this. There were some minor issues but never like this. It makes me wonder if the your project structure or the way project is written is crappy.
Well, just spend some time reading Android developer forums on Reddit, G+ or Google groups, every time there are new SDK or Studio stable releases. The dheera is not alone.
What I find hard to believe is that these problems would hit the same bunch of people every time, and on the top of it, affecting every project they work on. Come on.
And this is what dheera claimed ("almost every release of Android Studio has succeeded in breaking every single Android app"). If it's really so extreme, I'd say that he - or she - is not unlikely to be alone, or close to that.
