Decide on ANDROID_NATIVE_API_LEVEL
Closed this issue · 4 comments
We need to decide what we'll require for ANDROID_NATIVE_API_LEVEL - I'm not sure what goes into that decision. I know CrystaX improves compatibility for older API levels, so if we stick with that NDK we probably can get away with a lower value. David had chosen 19 - not sure what the reasoning was, maybe he can chime in (@davtbaum?)
Google Cardboard requires a physical Android device running Android 16 (Jelly Bean) or higher. This might be a good place to start.

I didn't see any relevant differences between 15 and 16 in the headers I expect that we use (did a comparison in the official NDK). Not sure which one is ICS, but ICS support would be handy if possible since I've got a cheapo tablet here that is easily (and already) rooted and running some old Android that I can't recall if it's ICS or JB. FWIW, OpenCV only needs 8, though there have been barcode scanners and such for a long time...
Locally I've been trying 14, seems fine to me
This was resolved in order to handle PIE/PIC issues in Lollipop.
