问题
I had set the ANDROID_NDK_HOME as /Users/Shajilshocker/Documents/Android/NDK/android-ndk-r10b using a mac osx application called Environment Variables.
I had confirmed that it set the path correctly in Terminal
echo $ANDROID_NDK_HOME
But when I run a shell file in a Android Studio project which invokes ndk-build I get the following error
ndk-build: command not found
How to make sure that ndk-build is in your build path ?
How to set ndk-build in my build path ?
Thanks for any help

Well, this is actually not enough to make the system aware of the path. You must add this path to the PATH system variable. In your case, all you have to do is to add the following line to your terminal configuration file (which should be under your home directory, named .bashrc if you kept the default terminal, full path: ~/.bashrc):
export PATH=$PATH:/Users/Shajilshocker/Documents/Android/NDK/android-ndk-r10b
What this line does is actually adding the path to your Android NDK directory to the PATH variable. You export a variable named PATH with its current content plus the directory of your NDK.
Step by step:
- Go in the home directory
- Edit
.bashrc - Add the line I showed above
- Save, exit, then restart bash (you just have to type
bash, then enter)

For mac use this: Open your .bash_profile file with a text editor. .bash_profile is by default found in home directory. Eg /Users/john
the assumption is: you have downloaded the android sdk and ndk to /User/john/Android or you can find the path from Android Studio by going to
Project Structure > SDK Location, pay attention to Android SDK location & Android NDK location
export ANDROID_SDK=/Users/john/Android/sdk
export ANDROID_NDK=/Users/john/Android/sdk/ndk-bundle
export PATH="$PATH:$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools:$ANDROID_NDK"
Then save the above lines to your .bash_profile file. Close it and try typing this on your terminal
ndk-build
if the response is like below, you are good to go
Android NDK: Could not find application project directory !
Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.
/Users/john/Android/sdk/ndk-bundle/build/core/build-local.mk:143: *** Android NDK: Aborting . Stop.
The assumption here is you have downloaded your android sdk to /Users/john/Android

In case this helps anyone, I installed the Android NDK using Android Studio on MacOS by following the instructions on the android.com NDK webpage: I selected Tools --> Android --> SDK Manager and then selected NDK. Android Studio then installed the downloaded files under:
/Users/user.name/Library/Android/sdk/
That directory is the same one that is listed on the SDK Manager window inside Android Studio. Underneath that directory is another directory ndk-bundle, which has all the NDK tools.
Thus, I added this to my path:
/Users/user.name/Library/Android/sdk/ndk-bundle/

cdto path you have to set.Enter in Terminal:
echo "export PATH=$PATH:$ANDROID_NDK_HOME" | sudo tee -a /etc/profile
