The android feature is optional and disabled by default. I think there
is no option to have the minimum meson version selected automatically by
features (e.g. require 0.55 only if android=enabled). In the official
documentation version 0.55 could still be required for android. But the
default version will build fine with 0.53 according to the official
build instructions.

Best,
Christian
