If you are building Augmented Reality applications for Android apps, Vuforia or QCAR might be one of the very useful library. However, you might also encounter the below warnings in logcat window, as shown below
The library libVuforia.so could not be loaded
There are several workarounds to troubleshoot this:
Approach I: In your project, there will be a file called “CopyVuforiaFiles.xml”, and there is a child element <fileset> where you should specify the right path to the libVuforia.so, change this path to the right directory where this file resides, that is it!
Approach II: recommended.
Go to the /vuforia/samples/libs/ folder where libVuforia.so resides.
Copy the “libs” sub-folder to your project folder.
Then in Eclipse, Package Explorer, you will find below hierarchies:
Rebuild your project, you will no longer see the warning “The library libVuforia.so could not be loaded”, everything should be OK!
