Loading large datasets in Android

September 27, 2017 - 8:38am #1

Hello,

It has come to our attention that changes in the behavior of the Android Build Tools (starting with version 25? we are unclear on the exact number) can affect the performance of device database loading times of the Vuforia SDK.

For smaller databases (less than 10 images), the effect may not be noticeable. However, for larger databases, the time to load can take several seconds or longer.

Camera does not Focus (Vuforia 9.3.3)

August 3, 2020 - 2:58am #1

Hi!

I'm currently working on an AR project that plays a video when a certain photo is recognized. I finally got everything to work after a few days but when I built the app on my Samsung S8+, the camera is very blurry. I even added a CameraFocusController code that multiple people have said to work on the ARCamera but the focus still doesn't work. I also tried different camera focus modes but still nothing worked.

Does anyone know why the camera fails to focus an how to fix this?

Your help is much appreciated. :)

BTW: I'm using Vuforia 9.3.3 and Unity 2019.4
