Describe the Issue

The upload task on has been failing quite often recently. We could reduce the size of the uploaded build directory by just including the files that are relevant. cc @jingtang10

@jingtang10 the build file contains build intermediates for all the module which take up a lot of space. The files for the demo app and the catalog app take up almost 1.5 gigs. Can we ignore these can just upload the release and debug apk instead?
