Android / React Native PDF Viewer and PDF Annotation SDK

Hi,

We're looking for an SDK that can help us with Android / React Native PDF capabilities such as annotations, a good reading experience. We're basically trying to build an ebook app.

Would love to tie up with you.

Thanks for your message, we have an Android PDF Viewer Application, we are also provide the Source Code License for this Android PDF Viewer, but this PDF Viewer application hasn't annotation function yet, if you need it, you could download the trial version or purchase it from this web page, after you buy its source code license, you can add the PDF annotation functions into this project by yourself,
