1). Android Studio is one of the worst pieces of software I've ever had to code with. The cursor randomly disappears while editing files. When a physical device is connected to the machine, it will sometimes screw up the sound and start playing out of the speakers even though your headphones are connected.
2). Every time you post a question in-regards to the IDE, there's usually a flurry of down-votes. But sometimes there'll be a person who says it's a known bug. Contrast that to questions critiquing xCode on SO, people will be generally happier to help out..
3). You can't organize your XML files in folders. Again, when I asked this on SO, people were arguing that what's the point of having subfolders.. Seriously?
4). It's fragmented as fuck. I feel like each question I ask, I have to always contain 2+ additional files to give context to a very simple problem.
5). It's tough discovering useful 3rd party libraries.. There's no gradle equivalent of cocoadocs.
I actually enjoyed programming with the Spring Framework, but this has just been disappointing all-around..
