EasyAR 3.0.1 Surface Tracking Camera didn't work on Android

Question

I trying to build HelloAR_SurfaceTracking scene to android but the result is black screen. And I didn't see any error on console.

If i play it on unity editor, the screen is work well showing the image on my webcam.

This black screen only happened in surface tracking, if I create an image tracking scene, its normal and work well.

Answer 1

Surface Tracking requires camera2 on Android which has compatibility problems on some devices, especially on devices manufactured with Android 5.0 and 5.1.

Can you provide your device model name and Android version?

I try to use my old phone runing on android 6 and only have 1 rear camera and its working. but the tracking is realy bad..
Redmi note 7 have 2 rear camera, I think this second camera is only for depth sensing, Is it maybe caused the problem?

Answer 2

i changed the camera size of the "AR Session" script in the scene to X (1920), Y (1080) and it worked on my redmi note 7
