Answer 1

Importing Eclipse Projects

Simpler Solution nowadays

All you need to do is "Import Project" in android studio to import eclipse projects. After that, try to "Syncronize project" and if it fails, and pops up that error u had, it should also be accompanied with an entry in "Entry log" as to what is the problem, "Cause: failed to find target android-10" for me. Once you fix that you should be able to successfully sync project and keep on going.
