PiPup

PiPup is an application that allows displaying user-defined custom notifications on Android TV.

The most common use-case for this application is for sending notifications, from a home-automation solution, to your Android TV.

Some example scenarios:

Show a snapshot of your camera on your TV (eg on a motion trigger)
Display a notification with the video of your camera when someone is at your door
Send a notification when your dryer/washingmachine is ready
Anything else you might find useful

The application is currently in a public beta

To enter the beta and install the application on your device go to:
https://play.google.com/apps/testing/nl.rogro82.pipup

Important: after installation / updating it is currently adviced to restart your TV and open the application once to make sure the background-service is running

Sideloading:

On Android TV (8.0+), when sideloading, you will need to set the permission for SYSTEM_ALERT_WINDOW manually (using adb) as there is no interface on Android TV to do this.

To give the application the required permission to draw overlays you will need to run:

adb shell appops set nl.rogro82.pipup SYSTEM_ALERT_WINDOW allow

Integrating

PiPup uses an embedded webserver (NanoHTTPD) which runs on port 7979.

Sending notifications

To send notifications with an external media resource (image, url or webview) use application/json
