Looks like we would need to build to API level 19 to deal.

I just tried with an android with Marshmallow (API level 23) on it and it's failing with a similar message

Implying that if the code does work on Androids, it does so only on the most modern ones (currently Nougat with API level 24 and 25) with the current market share of ~11.5% globally, and very likely a lot less in the countries of interest.

Looks like we would need to build to API level 19 to deal.

Yes, that is what my googling got me to believe as well. I think building dCDN with that API level shouldn't be a problem, it's the web view example app which seems to make use of the high API level.

Got it working with Marshmallow (NDK API 23) by changing this. I was however not successful with lowering that further (some compilation error I haven't looked much into yet).

Trying to run the android-23 version on an android-19 device now gives me the missing rand symbol error.
