As of now, we run Android tests on ARM (three ABI - armeabi, armeabi-v7a
and armeabi-v7a-hard), x86 and x86_64 targets. We'll add MIPS to the
list of active architectures as soon as will fix MIPS-specific issues
preventing us to run even simple C++ code which uses GNU libstdc++.
Also, we'll run tests on ARM64 (Aarch64) as soon as Google will release
ARM64 emulator or we could figure out it somehow in other way (having
dedicated Nexus 9 tablet constantly plugged to the CI server, for example).

In fact, it's important to test with all more-or-less actual API levels.
Android libc is very unstable and differ from one Android version to
another. We've tried to minimize such differences in CrystaX NDK, but
without thorough testing we can't guarantee it will work on all Android
versions. Please note Boost regression testing is not only testing of
Boost itself; it's testing of CrystaX NDK too. We already have set of
automatic tests where we test many things to ensure behavior is
POSIX-compatible, but having Boost tests successfully passed with all
API levels will make us even more assured there is no problems.

This makes sense for me. Thank you for pointing out.

Great! For me it definitely make sense. I just don't want violate rules
of community and make people discontented. As soon as having many
runners in results table is OK for you all, it's OK for me too.
