hi thanks for replying

i got this button on my camera screen.. now if i want this button to link another project ( e.g maps) what changes do i need to make in this imagetargets sample (if any). how can i call a project with this button.

Hi ,

Use ImageTragetsBuilder Sample , addOverLayView(),

I was able to achieve with  it.

In that case, you're simply overlaying a view on the GLView.

See the code in this thread..

Hi, thanks for replying. The issue is that these buttons come up only when the target detects. My query is to display a button to another activity,  irrespective of the target detection. This button should be constanly present on the camera screen. Can we do this in imagetargets app.
