Thank you for replying Strasza.

I have checked page you put.

It looks like in the bottom of the page there's an instruction with title " How To Use Device and Cloud Databases with User Defined Targets ".

However it may not be a solution for my problem occurring.

I'm sorry for not writing detailed my situation.

My application is made with Unity. Then I have already succeeded to use Marker recognition with dataset of both device and cloud, but not on the same build.

I have created 2 databases of both Type Device and Cloud on Vuforia Developer Portal, then imported  Vuforia SDK for Unity to my project and set up Vuforia Configuration. 

In Inspector of Vuforia Configuration,

When I check the checkbox [ Load MYAPPNAME Database] ,  marker recognition with device dataset works well, but the other with cloud dataset doesn't work.

When I uncheck the checkbox [ Load MYAPPNAME Database] ,  marker recognition with cloud dataset works well, but the other with device dataset doesn't work.

So I have to build 2 applications if I want to use marker recognition with device dataset and cloud dataset. 

In reality what I want to achieve is that use both device dataset and cloud dataset on the same build.

I apologize for my poor English.

Thank you.  

Hello Syuukouha,

Hi.

I am facing perfectly the same problem as Gallgall's post.

It seems there're already some answers, but when I try to jump to their pages they aren't available or exist anymore unfortunately.

In addition I have looked up other threads similar to this topic, then it was also impossible to show their urls in answers.

Any Advice or comment will  be appreciated.

Thank you.

Hi, Gallgall I try the same and.... it not work..... someone help us???

Hi, 

it is perfectly possible to use Cloud DB and Device DB simultaneously in your App;

the developer guide explains how this can be done:
