Question

I have made modifications to several example OpenCV projects within Android, however I am having some issues with using OpenCV successfully in a new Android project.

The documentation on using OpenCV with Android says to complete the following steps to add OpenCV to an Android project –

• ensure the Android project is in the same workspace as OpenCV
• add a reference to the OpenCV project by going to Properties > Android > Library > Add and choosing the OpenCV Library project

I have followed both of these steps, however when I compile my application I receive the console error –

Could not find OpenCV-2.3.1.apk!

Answer 1

When creating a new Android project, the only thing you need to do is

• add a reference to the OpenCV project by going to Properties > Android > Library > Add and choosing the OpenCV Library project

You should not then explicitly add OpenCV Library project into your new Android project’s build path:

• add another reference to the OpenCV project by going to Properties > Java Build Path > Projects > add…

If you do latter step, you will get the exact error Could not find OpenCV-2.3.1.apk! described in the question.

Check out the New Android project’s build path and remove OpenCV project if it exists, then give it another try and see if this helps.
