Access denied finding property "vendor.camera.aux.packagelist"

I copy part of the firebase-mlkit sample code only for Image labeling. When I run on my Nokia 6.1 and got the following error message:-

type=1400 audit(0.0:4015): avc: denied { read } for name="u:object_r:vendor_camera_prop:s0" dev="tmpfs" ino=17821 scontext=u:r:untrusted_app:s0:c7,c256,c512,c768 tcontext=u:object_r:vendor_camera_prop:s0 tclass=file permissive=0

E/libc: Access denied finding property "vendor.camera.aux.packagelist

I put the following permission in the AndroidManifest.xml.

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"    />

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

I can run the sample firebase-mlkit on the Nokia 6.1 without any problem. Any idea?

You need to export "vendor.camera.aux.packagelist" as a public default prop like:

vendor.camera.aux.packagelist u:object_r:exported2_default_prop:s0 exact string

in file([AOSP_DIR]/system/sepolicy/public/property_contexts)

I am not sure about the root cause of this issue but I was able to solve this issue by delaying to start camera preview in my App.

@Override
    protected void onResume() {
        super.onResume();    
    final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            camera.startPreview();
        }
    }, 300);
}

Don't forget to stop preview and release camera onPause event of activity.
