Android image A7A

I try A7A with android, Try I want to use it for very cheap android device testing my app. I paired it with android studio on Ubuntu24 via Wi-Fi. It work well with my simple app. I use android img from radxa page download at link below:

When my app need work with camera to scan a barcode, I try but can not open camera. Gemini AI of android studio check logcat of A7A and it say I need a other img version.
camera module is new.
And what I need to install for Android OS image that is certified to include Google Mobile Services (GMS). google service framework apk say failed and need close so, I uninstall it.
Some app like zalo at my local region need GMS service to work, and some other app. Currently, I can not use google play store, only use apk from apkmirror

Radxa Cubie A7A , Radxa 13M 214 Camera - Cubie Series / A7A - Radxa Community
After checking the link above, I change 13M camera to model for raspberry, and I also use convert cable from RADXA for rasbperry camera, and my app can open camera and work well.
I still not figure out how to install GSF and GMS service of google for ZALO and play store. And I wonder how to connect 2 cameras to A7A? it is 4 land CSI and I do not find special adapter on RADXA store or taobao for that purpose.
