/**
 * Quirk that displays a notification when an image in {@link android.provider.MediaStore} has
 * been deleted.
 *
 * <p> When triggering an image capture, the {@link androidx.camera.core.ImageCapture}
 * use case validates the save location before starting the image capture pipeline. Validating a
 * save location that is a {@link android.net.Uri} in {@link android.provider.MediaStore} involves
 * creating a new row in the user defined table, retrieving an output {@link android.net.Uri}
 * pointing to it, then attempting to open an {@link java.io.OutputStream} to it. The newly
 * created row is deleted at the end of the verification. On Huawei devices, this last step
 * results in the system displaying a notification informing the user that a photo has been
 * deleted. In order to avoid this, validating the image capture save location to
 * {@link android.provider.MediaStore} is skipped on Huawei devices. See b/169497925.
