hi, Can you solve your problem? I have some problem. I'm using Vuforia AR camera and image target. My app. size 138 mb. I must split this app. I'm using Unity 2017.2.0f3. I'm doing "split application binary" at Publishing settins. I loaded apk and obb files on google play store. But it's not running when downloading my app. App is running first scene(menu). Buttons running. At the same time, there isn't vuforia at first scene. But AR camera is not see image target. 

what can I do? or what can it cause this problem.

Hmm, So would you recommend having a "starting scene" which somehow loads up the "StreamingAssets" (with a script looking something) and then do a simple sceneManager and transfer into the next scene where vuforia and the app will run?

The “StreamingAssets” folder where the Vuforia datasets are stored is one of the locations which Unity will store in the OBB if the APK exceeds 100MB. The existence of the necessary datasets in “StreamingAssets” should be confirmed prior to starting Vuforia. It is recommended to not have Vuforia/ARCamera included in the first scene if the APK is split. See these additional links for more details:
