I've been working on some Android application in Unity lately and with just two USB ports on my MacBook, it is annoying to remove the mouse and keyboard to plug in my Android device when building.
But this can also be done wirelessly using
On Mac it is really easy to to get up and running. Using Homebrew just write:
brew install android-platform-tools
Plug in your Android device and write:
adb tcpip 555
Unplug device and write:
adb connect deviceIP
Now you can just build like normal in Unity.
