I decided to write a post about this because I had a lot of trouble until I make it work.
And this was my first Android App 😦 .
I googled a lot trying to connect, first I tried to get data from SharePoint using API’s which then I had problems in authentication my connection then after I get data successfully I said ok I will post data successfully too.
And what you think happen, will it wasn’t a successful first try, I had another security errors.
So I had this mad week trying to collect the pieces from all the articels and posts. and voala it worked. And really I didn’t find a one place that have every thing in details that helped me, so I decided to do it and post this detailed code for every thing to connect.
