The camera's permission is disabled, that's why you are getting this error. Simply follow the code given below, the camera will start working as well as your scanner which depends on it.

Under MainActivity.Java file / asw_view.SetwebChromeClient. Post this code

@Nullable
			public Bitmap getDefaultVideoPoster() {
				return Bitmap.createBitmap(10, 10, Bitmap.Config.ARGB_8888);
			}
			@Override
			public void onPermissionRequest(@NotNull final PermissionRequest request) {
								final String[] requestedResources = request.getResources();
				for (String r : requestedResources) {
					if (r.equals(PermissionRequest.RESOURCE_VIDEO_CAPTURE)) {
						request.grant(new String[]{PermissionRequest.RESOURCE_VIDEO_CAPTURE});
						break;
					}
					if (r.equals(PermissionRequest.RESOURCE_AUDIO_CAPTURE)) {
						request.grant(new String[] { PermissionRequest.RESOURCE_AUDIO_CAPTURE});
						break;
					}
				}
			}

Add the line under websettings webSettings.setMediaPlaybackRequiresUserGesture(false);

And make sure record_audio and camera permissions are granted in android manifest xml.

replace @NotNull with @Nullable also import import androidx.annotation.NonNull; import org.jetbrains.annotations.Nullable;
