Hello

Is there any demo or code snippet of Java API for tracking  .

https://library.vuforia.com/content/vuforia-library/en/reference/java/index.html

I found above reference link for Java API, but I found it difficult to understand how to use the API . If you can provide some code snippet on  detecting image target  and get callbacks while tracking state changes it would be very helpful. I have a requirement to render 3D models fbx/obj after that but I understand Vuforia do not support this currently. If anyone can provide some source code for same I would be grateful.

Currently I am using the sample application vuforia-sample-android-9-2-7.zip available at following link but this do not make use of Java API instead it is using cpp code.
