Setup Android NDK

Unity version: 5.3.4f1 (64 bit).

I have Android studio installed on the same PC and used the Android SDK manager in that to install the SDK and NDK (amongst other things), with the NDK sitting in the folder c:\users\AppData\Local\Android\sdk
dk-bundle

When I try and set up the paths for android in Unity Edit>Preferences>External Tools it allows the sdk path fine, but when I put in the above path for the NDK I just get the message “Unable to detect NDK version, please pick a different folder”.

Had the same problem. Android Studio installs NDK r11e and seems unable to install any other version. However, Unity wants r10e specifically. You have to install it manually, e.g. by using the download button within Unity (Edit → Preferences → External Tools → NDK).

i fixed all these things but it still doesn’t work
any idea please

That all ways not work on windows
