Support of the official raspberry Pi camera on android-rpi

I am currently using android-7.1.2_r19 on my raspberry pi 3.
I would like to get working an official Rapsberry pi camera v1.3 or v2, connected through the CSI port of the raspberry pi.
I installed a camera apk but when launching the application it crashes with error CameraService::Connect rejected (camera Hal module not loaded)

Is there anything to do to add support of official rpi camera on Android (modify the rpi3.mk, init file, buils some additional code - camera hal- ...)
If anyone has succeded, help would be much appreciated.

Hasn't anyone used the camera using android-rpi on raspberry pi.
If I add camera.default in rpi3.mk to add default camera hal to the compilation, I then have a crash:

Anyone can help ?
PS: camera is supported (at least USB camera which I tested) on android-things. From the trace I saw that the following camera hal is used: V4L2CameraHAL

Not sure if I should try to to integrate this on android-rpi or debug the above crash using default camera hal

issamy commented

Still trying to get USB camera working with default Camera application on Android rpi.
Tried to integrate v4l2 camera hal from https://github.com/antmicro/android-camera-hal
Now able to initialize the camera HAL but a gralloc memory allocation failure occurs.
Any help ?

I am also facing same error.
have you got any solution?

Hi Vinay,
Unfortunately, I have not been able to solve this "out of memory" error and I had to give up trying to get the camera working for now.
If you or someone else finds a solution, please share the solution for the community ;-)
