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 or higher (SDK 34+), 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
