This is on a brand new project generated by flutter create. flutter devices sees my phone. flutter run or flutter apk from command line, same error. flutter build seems to work.

Ubuntu/VirtualBox

I checked the existence of all the fixed files. Seems to be related to one of the temp paths. Any ideas?

Issue 2:
In compiling an app via flutter start you can get an error saying it can't find/execute aapt.

This is due to the issue outlined here:

http://stackoverflow.com/questions/19523502/how-to-make-androids-aapt-and-adb-work-on-64-bit-ubuntu-without-ia32-libs-work

I ran into this over the weekend and without stumbling across that stack overflow I wouldn't have been able to get my flutter app to work for android.
