Comment (by sysrqb):

 Replying to [comment:48 sisbell]:
 > Yes, this is the error that shows up if we don't use 21 or 22 NDK. I
 previously had a patch that  could make it run on other versions but I
 think it would be better to use a version of the NDK that doesn't require
 a patch. I'm ok with either 21 or 22, I just chose 22 since I default to
 the highest compile version is best, due to possible bug fixes.

 sisbell, can you post the patch needed for successfully building against
 android-9? In our current code the default is android-9 for non-x86 CPU
 targets, it is 21 for ['aarch64', 'x86_64', 'mips64'] cpu targets.

 In August Mozilla bumped their versions:
 https://hg.mozilla.org/mozilla-central/rev/2b2bd723ebc8

 and now their default is [https://hg.mozilla.org/mozilla-
 central/annotate/c291143e24019097d087f9307e59b49facaf90cb/build/moz.configure
 /android-ndk.configure#l23 android 16].

 I prefer not making drastic changes like this (jumping from android-9 to
 android-22). Mozilla are very conservative about when they make these
 changes with good reason. For changes like this, i wish we had a working
 test suite. If we use this, then we need a lot of testing over the week
 before we release the next alpha version.
