Hi, it appears from the logs that you have probably not built the native part of the project;

you should use ndk-build to do that and then refresh the project in Eclipse.

Please check the dev guide here for how to build a sample project:

Hi,

you will need to do the following:

  1. go to the online Target Manager 
  2. create a New Device Database
  3. Upload a new target ("planar target") to the Database
  4. Wait for processing to complete and then download the Database to a ZIP file
  5. Then in your ImageTargets sample, in ImageTargets.cpp, you will need to replace the "ChipsAndStones.xml" dataset (in the function dataSet->load()) with the name of your DB XML .

The full process is documented in this page (and related links to various subsections):

https://developer.vuforia.com/resources/dev-guide/image-targets

Please read that and follow the process as described.
