did you solved this error?
Am also getting this error

I thought I would add a bit here that hopefully helps. There could be a number of reason why you are getting this error. Read through your logs before and see if it gives a clue. Some just needed to delete their Intermediate folder and it worked. Many had to go back through their Android Studio setup and make changes.

A way to isolate the problem (if say removing the Intermediate folder does not work) Would be to build a totally blank project with a basic level that works with your headset. Then try to package and/ or launch the project to your headset. If this works, then you have isolated the problem to some extent and will not have to look towards rebuilding or re- installing Android Studio and dealing with settings. From there, it could be something within your current project, asset or setting other than anything regarding Android Studio that is causing the problem. Hope this helps, sometimes you have to troubleshoot what does work and go from there,
