I'm using two libraries under Apache 2.0 license opennlp and crux. The source code of my Android opensource app will be on Github. And the app will be released on Google Play Store. What are all my obligations to these two libraries? (What to include in my source code on Github and in my app on Play Store). What is obligatory and what is optional?
I'm using in my project jsoup as well, two times. Once on its own and another time via crux which uses Jsoup as well. Jsoup has MIT license. Is it sufficient for my project to have Apache 2.0 license?
My app will be free and open source.
