        // return my file

Try creating an explicit javax.ws.core.Response :

return Response.status(Response.Status.OK)
                .entity(entity)
                .header("Content-Disposition", "attachment; filename=" + fileName)
                .build();

while entity is your file as byte array and fileName is the file name with .apk suffix.
