Okay thanks for the help.

Users again have to create new UDT when they launch the app because it will count as the new app session.

Correct. If the app is paused/backgrounded, then the session information should be retained and the UDT targets stored in memory can be detected and tracked. However, if the app is quit, exited or the device shut down, then the session is over and the targets will no longer be available.

These UDT trackables cannot be stored, exported or shared with other devices/users/sessions.

And No I haven't looked in the cloud reco thing yet I'll look now and see if that helps or not. If you can explain how I can achieve all the things I said in my post  https://developer.vuforia.com/forum/vuforia-api/user-defined-targets#new  tha would be really helpful.

And Thanks for the help.

Hello,

This is possible with the Vuforia Engine User Defined Targets feature, with the following limitations:

• Targets are only persistent for a single user, on a single device and the given app session. User Defined Targets only reside in memory and cannot be exported to other users/devices
• Single run time database supports up to 5 individual, user-defined targets
• Recommended maximum of 10 simultaneously tracked unique, 2D planar targets across all active datasets. A maximum of 5 of those targets can be User-Defined images

Have you considered our Cloud Reco feature? Each target has a metadata payload of 2MB: https://library.vuforia.com/content/vuforia-library/en/articles/Training/Cloud-Recognition-Guide.html

Hey is something like that is available now. I am using a user-defined target sample app it stores targets only when an app is running as soon as I close the app the save targets got deleted. I want to build something like user can click a picture as an image target like in sample and whenever that sample again gets detected it should play some audios. So is it possible with user-defined targets. Any help would be appreciated. 

Thanks.

You're welcome.

Ah thank you.
I had not seen the wish-list, sorry.

Hi, we don't have an ETA for that at the moment; have you already posted that request in the wish list ?
