As you have pointed out, we stopped building Flym when it required
play-services. As of 1.9.7 this is still the case. If you can
convince upstream to remove it or provide a build flavor that does
not require it, we can start building it again. Please keep in
mind that upstream most likely is busy working on the 2.0 version
on a new code base, so patches to 1.x will most likely be slow.
