Which Android Operating Systems are supported by OpenCV?
It seems that the bare minimum in the examples is 3.0, but does anyone know if you can support older devices? Also vice versa, can it support ICS? How about 4.1 or 4.2? I can’t seem to find specifics anywhere and I don’t want to buy a test device that it’s not going to work on.
It supports all releases starting from Android 2.2 (API level 8).
The minimum you see in examples is a compile-time only. The code checks current OS version at run time and chooses better implementation if the API level is high enough, otherwise it fallbacks to legacy implementation.
