I have been using Vuforia for 2 years but since Vuforia 5 I have a strange behaviour with the android “split binary” function.

My app is bigger than 100 mo so I need to split it to publish it to PlayStore.

Please find attached the script I use to load the vuforia dataset from the expansion file.
I assign the dataset name and the two image target in the scene.

Vuforia only works the first time the application is launched, just after the installation.

To make the application working on the second/third launch etc. I need to clear all the data of the application in the android menu (clear cache and clear data)…When I do some debug I cannot see any error in the log, the dataset is correctly loaded from the expansion file in memory but the tracking does not work / the augmentation is not visible :(

I am using Vuforia 5.5.9 on Unity 5.3.5.
