Hey guys

I did all the steps on the Getting Started But when I try to install the app I get this error. Probably something wrong on my machine. How do I fix it?

Awesome, man! It works! I just had to execute again:

$ buck kill && rm -rf buck-out
$ buck build demo_app_android

Thanks a lot. This error was causing me headache for months

Ok, it looks like you don’t have Android NDK installed.

You need to install Android NDK from here (version 10e) and set ANDROID_NDK_REPOSITORY to the location of the unpacked NDK (see buckconfig section for more info).

For example, if you unpack NDK to ~/tmp/ndk (so that there is a directory ~/tmp/ndk/android-ndk-r10e), you need to set ANDROID_NDK_REPOSITORY to ~/tmp/ndk.

From buck side, we need to update the documentation and not allow to build an APK without NDK.
