Middor

Mirror applications for HUD display with horizontal flip.
New in version 0.1.7
## Changes

- feat: added warning for Android 14 devices about requiring minimum QPR2
- deps: bump package versions (jetpack compose)
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. For more details, see Android 14 - App Screen Sharing: https://developer.android.com/about/versions/14/features/app-screen-sharing

For usage instructions, see https://github.com/nktnet1/middor/discussions/2

Permissions


  • SYSTEM_ALERT_WINDOW: to draw a mirror overlay on top of other apps

  • 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
