Android SDK - ImageTracker class error

By pabmeister on Fri, 12/19/2014 - 10:44

I have replaced the SDK 3 files with the new beta files in my Vuforia sample project, and I am getting an error saying 

"Error:(33, 28) error: cannot find symbol class ImageTracker"

in the following files:

  • CloudReco.java
  • CyclinderTargets.java
  • ImageTargets.java
  • MultiTargets.java
  • TextReco.java
  • RefFreeFrame.java
  • UserDefinedTargets.java
  • VirtualButtons.java

Anyone else getting this?

I can't see anything in the change logs about this class being removed, and the new documentation points ot the same old sample files

Hi, with SDK 4.0, the ImageTracker class has been replaced with ObjectTracker class; simply replace your occurrences of ImageTracker with ObjectTracker in the code:
