Migrating to vuforia 4.0

Please share any guide for migrating android project using older version of vuforia to vuforia 4.0

 

 

Thank you very much for the reply

 

I had checked those links

it is for unity projects 

I am having a normal android java project.

I have that native files in jni folder from which i generate .so files and use the vuforia.jar file

This is the content of that link .

Though it says ANdroid, the instructions are Unity

Yes my code and DOminoes has Jni

I did a ndk-build to generate .so

then compiled java code

compilation is perfect

problem is while running

i suspect the .jar file is wrongly added because when i run old version of my app with new jar file , it is working !!

ImageTarget sample also have Native code.

I tried VideoPlayBack sample.

It builds while running crashes with
