I'm a mobile developer but work on iOS, from what I see and hear from my colleagues, the Android stack has gone through a bit of upheaval in the last year or so. Maybe, like someone else here said it could make sense to build a small app with the newer technologies and put it on Github and/or release it to the Play Store. With 13-14 years experience I'd say you're still in a really good position despite the job market. Demand for senior people remains constant and platform experts are also in high demand while web development absorbs a lot of the entry level developers. There are less positions for mobile but also far less competition.
