I can't find any references that justify these changes in the NDK, but they only seem to be in API 21. r10d and r10e both have the same issue.

The same problem was observed in the issue/PR for p4a master, with the solution being to switch the architecture target from armeabi to armeabi-v7 for these APIs. I guess we just have to do the same, but the Architecture stuff in the revamp isn't fully finished and it will be necessary to go through and make all the references correct. This would also be a step toward multi-architecture APKs.

Aha, I'd forgotten that I'd seen this in #410. Thanks for reminding me.

With the new arch support, this should now be easy to do.

It would appear that at least as of Kitkat 4.4 (API 19), ARM devices are required to be at least ARMv7a:

MUST report, via android.os.Build.CPU_ABI, only one of the ABIs listed below
* armeabi-v7a
* x86
* mips

It's not altogether surprising that the API to follow 19 (Lollipop API 21) would drop support for ARMv5 completely. From what I've read, official builds of 4.4+ are always ARMv7a, but there are some custom builds for certain devices which run ARMv6.

So the fix is to target a lower API or target the armeabi-v7a architecture. Switching to v7a fixed this problem for me.

Reopening, because I realize we can actually do something here. Maybe make p4a automatically select armeabi-v7a if API >= 21 and --arch was not specified, and if --arch is specified and is not compatible, then error out.

I added a check in a recent PR that causes an error and build failure if the api is too high (so that the user knows what's wrong and can pick a fix).
