Question

When running the ndk-build command I get the following error:

Android NDK: Could not find application project directory !    
Android NDK: Please define the          


        

Answer 1

You need to specify 3 things.

NDK_PROJECT_PATH - the location of your project
NDK_APPLICATION_MK - the path of the Application.mk file
APP_BUILD_SCRIPT - the path to the Android.mk file

These are needed to override the default values of the build script, which expects things to be in the jni folder.

When calling ndk-build use

ndk-build NDK_PROJECT_PATH=/path/to/proj NDK_APPLICATION_MK=/path/to/Application.mk

In Application.mk add

APP_BUILD_SCRIPT := /path/to/Android.mk
