(FTC) Using Android Studio - cwm9cwm9/TTGT-FTC-FRC GitHub Wiki
The REV Hardware Client MUST be running for the Control Hub to be visible to Android Studio.
The REV Hardware Client can't see the robot unless you are wirelessly connected to it.
In order to automatically start the Robot Controller app once deployed, go to Run->Edit Configurations, then under Launch Options, change Launch: to "Default Activity."
