I'm writting an application that can load Dataset from internet at runtime ( i'm using QCARV1.5)
I heard that QCAR v1.5 supports this.
is there anyone have experience about loading dataset from internet at runtime with QCAR v1.5?
回答1:
you can download Dataset from server and store in sdcard then in imagetarget.cpp in loadTrackerData change QCAR::DataSet::STORAGE_APPRESOURCE to QCAR::DataSet::STORAGE_ABSOLUTE.
Everytime you download dataset just replace old one before calling load dataset from java,this will work.

They have announced that the next version of Vuforia will be cloud-based which fetch the data from Internet. But meanwhile, the answer that @yogi has given is the best choice.
This is not actually related to Vuforia but it's just downloading file from Internet in Android.
