I have running the native emulator running Android Studio 2.1.2, I find that only once does the application load me into the emulator, and the following times I give it to compile I get the error:
Error while Launching activity

It seems to be a problem with the AS version when the AVD tries to use the same .apk with the "Instant Run" option.
It could be a solution to disable the option for this case:
File > Settings > Instant Run deselect "Enable Instant Run"
