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

Question

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?

I solved it by reducing the library versions in build.gradle — Sanidhya Kumar, May 29 '19 at 11:40
@sanidhya09 Thank u so much for the hint! It was one of the firebase library that was causing the error. — Prajwal Waingankar, Jun 15 '19 at 22:15
Did you find a solution? I have the same issue with Redmi 6 pro. — Rockers23, Sep 27 '19 at 12:57
@SanidhyaKumar can you give your solution. I will offer immediate bounty — Ranjith Kumar, Dec 11 '19 at 11:18
@RanjithKumar i reduced the library version of arcore and sceneform. If you are not using these then try finding which library in your gradle is using camera 2 apis. I used Arcore 1.7 — Sanidhya Kumar, Dec 18 '19 at 12:50
I'm somewhat facing the same issue where im using some android camera library (background camera), and im running it as a service through work manager class periodically, the app works for first few hours but then later makes my entire device hang, and i see the log to find this error, so I removed firebase also from my app, still facing the error, so any solutions for this? — rohit901, May 31 '20 at 09:21

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.
