I'm porting native Android Mail client and I would like to have Exchange support. While porting Exchange which I found here i found that patent disclaimer thing. What does it really mean for me? Should I be worried that MS will hunt on my application?
Microsoft gives for Exchange support this EWS Java API, should I move to that implementation? What's the difference for MS if I use EWS Java (which source code is available) or I use that Google solution?
If anyone can write about experiences about that I'd love to read about that.
