As it is a hack using private API it might break, sure. But I don't expect it to break before 2038 :). If it breaks it's not fatal for the app (crash). Btw above code snippet should catch Throwable to catch potential although unlikely UnsatisfiedLinkError.
I've tested above code on 2 devices, with and without WMA support. With slight modifications, above hack can detect WMV support as well. No need to say to resort to such hacks sucks...
