Bundling is not yet implemented in editor 2 I’m afraid.
I seem to recall an issue with targeting a device through editor 2 as well: Engine crash on remote device when building to target · Issue #578 · defold/editor2-issues · GitHub
It is tagged as a blocker so the issue has high priority. In the meantime maybe using editor 1 will allow you to move forward 
EDIT Have a look at the forum post referred in the github issue: Is latest dmengine.apk from d.defold.com compatible with latest Editor2 builds? - #4 by britzl
