Hello every one, I encounter this error often. and I failed to resolve it. I found on the net that it is necessary to have an NDK 14b in order to solve this but it does not work for me.

Any idea or proposal is welcome. Thank you.

Hi, thanks for the reply. For anyone who looking for the solution, I was able to fix this. In my case, it's related to ndk.dir in local.properties. Set ndk.dir point to the android-ndk-r14b ndk directory. Download at: https://github.com/android/ndk/wiki/Unsupported-Downloads
