Modernization and adb deletions

[trevjonez]

follow up to https://github.com/gojuno/commander/pull/28 obviously this would fail until that is published but figured I would post them round about the same time.

restating from the commander PR:

Sorry for the PR bomb, just trying to get some tickets going on the composer repo since they are now bubbling up to the gradle plugin repo as development seems to have slowed on commander/composer.

this is in support of: gojuno/composer#16 gojuno/composer#150 gojuno/composer#160 trevjonez/composer-gradle-plugin#48
