There used to be an ECL+Maxima app for Android, but it fell in one of the purges of older programs from the Play store a while back. I was always surprised it didn't use ABCL.
Some folks have such a Java allergy that they rather endure the pains of NDK tooling, than accept a bit of Java on their efforts, I imagine.
I wouldn't assume ABCL runs on Android. It's not listed as a supported runtime on their website.
ABCL is really slow.
