As I continue my adventure into Android development, pair programming has been a huge help in learning this new platform. When it’s time to build and run the app, relying on the emulator is a fools’ game — the emulator is slow and it’s hard to reliably simulate gestures.

If you have an android device, like a phone or tablet, you can plug it into your computer and mirror the display to your computer using an awesome utility called scrcpy!

Start by installing scrcpy with Homebrew:

brew install scrcpy

You may also need to install adb:

brew cask install android-platform-tools

Once you have scrcpy installed, you can start mirroring your Android phone to your computer by executing the command:

scrcpy

The Android device, whether phone or tablet, obviously must be connected to the computer at the time. The mirroring is super responsive and much nicer than an Android emulator. I love using scrcpy to pair program or record videos of app interactions.

When I first started Android development, I was worried I’d be stuck trying to use an emulator to demo features or bugs. Big thanks to scrcopy for making Android life easier!
