Android Studio (Windows 7) is giving me the "Unable to create debug bridge" error, as this person describes:
Unable to create Debug Bridge: Unable to start adb server: Unable to obtain result of 'adb version'
I have tried pretty much every solution I've found and then realized that I just recently installed Xamarin for Visual Studio 2015 as well, and I'm thinking that has screwed up Android Studio. adb works fine from the command line. A Google search didn't turn up any relevant results for this issue but I'm hoping someone can at least confirm that these IDEs don't play nicely together, and ideally even present a solution. I can do my installation from the command line but of course that's a pain compared to just clicking a button in the IDE, not to mention the inconvenience of using the command line to view logcat.
