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.
