Description

Middor is a free and open-source Android application for mirroring apps on your device. With built-in support for horizontal flip and 180° rotation, Middor can be used to:

  • Display apps on a HUD
  • Project content onto a car windscreen (e.g. Google Maps navigation)
  • View mirrored images and videos
Middor only supports devices running Android 14 QPR2 or higher, as it relies on the single app screen sharing feature.

  • FOREGROUND_SERVICE: to run the mirror service continuously while the overlay is active
  • FOREGROUND_SERVICE_MEDIA_PROJECTION: for capturing the screen content of the underlying app
  • POST_NOTIFICATIONS: (optional) to display the mirror service notification with additional actions
