Have UE4.5.1 been perfect support any Android system

I want to know which version of android system can be support by UE4.5.1

We’ve been using SDK and NDK level 19…

FYI, we’ve just switched to support SDK 21 (but still using NDK 19) for 4.6. The reason that we won’t use NDK 21 is that code compiled with NDK 21 headers won’t run on OSs before 5.0. SDK 21 won’t be required tho, but it will be supported.
