Prev build will crash on android 12 because it claims to know about
sdk 31 but gets Bluetooth permissions wrong. It's been released on
fdroid due to miscommunication. Fix will be to roll non-gplay variants
back to 30 for now. I'm deliberately breaking gplay builds because
nothing should ship there until I sort out the permissions stuff 31
requires. (Shipping 30 is no longer possible for the gplay store.)
Required redoing how I invoke the NDK. The limititations I had to hack
around before seem fixed, so this is probably better. But there will be
glitches. :-)
Crittercism is dropping free support of FOSS apps, so I'm dropping
it. Unfortunatly integration isn't as clean: so far at least I haven't
figured out how to make it possible for others to build the 'd' variant,
which includes Crashlytics, without their having a Fabric API key.
