Let maplibre render maps to Cars head unit using Android Auto

[mchakkarwar]

Hello,

I am using custom maps styles on our own cloud. I want to render it on Car's head unit directly with the help of maplibre.
The suggested method is to pass surface object got in onSurfaceAvailable in Android Auto car apps library.

I want to pass this surface to maplibre to draw maps onto car head unit surface.

In short I want to use car's GPU for drawing map using maplibre.

Anybody can help me to achieve this? Any already available libraries help to achieve this? Any Approach?

Thank you :-)

Hello @louwers

Thank you for quick help !!

I have followed approach given in https://github.com/maplibre/MapLibre-Android-Auto-Sample, but in the readme it is mentioned "We render the MapView offscreen, create a 'screenshot' of this view. And we'll draw this Bitmap to the Surface via a Canvas. Repeat the process 30 times per second, and you've got a working MapView on Android Auto, this process is not very efficient".

So, I need some approach that renders map directly onto car's surface.

Could you please help to understand your approach? Have you raised some PR against https://github.com/maplibre/MapLibre-Android-Auto-Sample?
