1) Do internships or co-ops. 2) Write your own apps and use them as demos. 3) Apply anyway and hope you get lucky enough to get an interview, then sell it well.
Basically the same as everyone else. If you already have all the experience the job requires, it'll be a boring job. If you don't, you don't perfectly fit the description and have to be good at sales. As someone who's switched fields three times, it ain't easy getting into one where you either have no relevant experience or no recent experience, but it is possible. Target jobs you like and tailor a resume and cover letter. Then send a more generic one to jobs you may not like as much and use any interviews you get as practice. You might even get a job by accident that way!
