Live-code

Save your XML / Java / Kotlin / PNG files. Check on devices in seconds. Rapidly experiment your layouts, custom views and animations.

Prototype

Create full-fidelity prototypes and collect early feedback before coding Java. Reuse the code in production when the prototype is approved.

Collaborate

Trash design specs. Sit with your designer, make a change and get instant feedback. Encourage them to create the layouts too!

It’s absolutely awesome. I worked an entire afternoon on an animation for my app, without the sandbox I probably need more than a full day.

I found that Mirror really sped everything up for us in Android Studio. Mocking up things with dummy data is a nice touch.

Hot-swapping
  • Mirror compiles incrementally and only sends deltas to the devices — much faster than rebuilding and reinstalling the full APK.
  • Hot-swapping resources, assets, and Java / Kotlin code on multiple devices
  • View states on the layout are preserved across refreshes

Accurate, interactive previews
  • Mirror’s previewer app inflates layouts and renders views the same way as your app does (it’s a normal Android app anyway).
  • Touch feedback, gestures and animations are as accurate as they should be.

REPL for Android UI development
  • Experiment individual methods
  • Feed and test your custom view with different datasets
  • Build animations piecewise
  • Use code in production when ready

Custom views, custom fonts
  • Preview layouts with third-party libraries or your own custom views
  • Live-code custom views and custom adapters
  • Preview custom fonts, custom attributes

Great for learning Android coding
  • Learn Android’s layout/resource system by building things that work on the real device
  • Experiment UI related APIs
  • Learn by doing in a fast feedback loop

Sample data
  • Build your UI in a realistic context before coding Java
  • Simple XML to set text, image, visibility and more
  • Populate list and grid views with different item layouts
  • Use Android’s “tools” attribute to populate views
