E/libc: Access denied finding property "vendor.camera.aux.packagelist"
        Access denied finding property "vendor.camera.aux.packagelist2"

AndroidManifest.xml

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

build.gradle (Module:app)

apply plugin: 'com.android.application'
android {
    compileSdkVersion 28
    defaultConfig {
        minSdkVersion 22
        targetSdkVersion 28
        versionCode 1

            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }

        jcenter()
    }

First, check your Android version. If it is running on Android 6.0 and higher (API level 23+), then you need to :

Declare a permission in the app manifest. Make sure to insert the permission above the application tag.

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

<application ...>
    ...
</application>

Then, request that the user approve each permission at runtime

if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA) != 
PackageManager.PERMISSION_GRANTED) { 
ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.CAMERA}, 
50); }

I had this in my android manifest that prevented the app from using the camera.

android:hardwareAccelerated="false"

Removing it helped me.
