Android Studio ndk.dir issue

Looks like the environment path and the local.properties files are pointing to different locations:

PATH: C:\Program Files (x86)\Android\android-ndk-r9d

local.properties: C\:\\Program Files (x86)\\Android\\android-studio\\android-ndk-r9d

Make sure which is right. You can keep the PATH and drop the local.properties declerations, and then try this command through the console: ndk-build -? to see if it was found in PATH

I had a similar problem to realise only that just the NDK was not installed (same error message).

I simply went to the SDK Manager in Android and installed NDK bundle.

Post that I just selected the default path in the settings and it worked.
