Deeplearning4j: Android Build Error by using 1.0.0-beta4: Program type already present: org.opencv.android.BaseLoaderCallback$1

[zhangy10]

Issue Description

I am switching the dl4j from 1.0.0-beta3 to 1.0.0-beta4 by changing the Gradle file. However, I got the below build error:
Program type already present: org.opencv.android.BaseLoaderCallback$1.

The 1.0.0-beta3 works well for my application, but the 1.0.0-beta4 seems to have a classpath conflict. So, can you please double-check this issue?

Additional Information

Here is my Gradle file for your reference:

We need to update the dependencies like shown in the examples here:
https://github.com/deeplearning4j/dl4j-examples/blob/master/android/DL4JImageRecognitionDemo/app/build.gradle

Thanks for that @saudet. So, the example code works well, but I think you should update the documentation: https://deeplearning4j.org/docs/latest/deeplearning4j-android. It doesn't show the updated dependencies. Anyways, thanks again.
