Add an example code for Android

[hnvn]

This example contains an implementation of CvCameraPreview that fetches image data from physical camera, convert data to Mat, expose an interface for OpenCV processing, then render processed image data in a SurfaceView.

Looks good! Just a couple of things:

• Remove the .idea folder and/or add it to .gitignore
• Rename the com.javacv package to something sensible like org.bytedeco.javacv
• Since we already have a JavaCV-android-example project, could you either:
  • Update that project with your files
  • Use another name for this project like javacv-android-display or something
• Fix typos (mainly exmaple -> example)

Thanks!

Thanks for your changes, let me know when you are done! Thanks

[hnvn]

I already finished my work for example

[saudet]

Ok, thank you, but could you also change the things I mention in my comment above?

[hnvn]

I changed something according to your mentions. You can review and tell me any still existing problems.

[saudet]

Great! But yes, please fix the following:

1. Rename JavaCv-android-preview-exmaple to javacv-android-preview-example (although the other Android example also does preview, so we might want to have a better name...)
2. Remove all the .gitignore files that are not in that directory
3. Update the com.javacv reference to org.bytedeco.javacv

The rest looks good so, once this is done, I'll merge this! Thanks

[hnvn]

Done! Everything seems Ok. Please check again and tell me anything wrong.

[saudet]

Ok, thanks! Looks OK, just one last thing: Please remove the .gitignore file in the top directory. Feel free to use one in your project directory though.

[hnvn]

Done

[saudet]

And the directory name is a bit long. Let's settle for "javacv-android-camera-preview", would that be OK?

[hnvn]

It's ok now

[saudet]

Great! Awesome. Thank you very much
