Answer 2

NDK_PROJECT_PATH is an environment variable so you don't have to include in the Android.mk file. Is nkd-build launched in the project directory?

For more info read the docs in docs/HOWTO.html in the NDK folder where I read

Starting with NDK r4, you can simply place the file under $PROJECT/jni/ and launch the 'ndk-build' script from your project tree.

If you want to use 'ndk-build' but place the file to a different location, use a GNU Make variable override as:

ndk-build NDK_APPLICATION_MK=/path/to/your/Application.mk

Answer 3

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

Answer 4

Set your ndk builder's working directory could solve your problem as I got the same problem and solved it in this way.

Path: Project Properties -> Builders -> -> Main -> Working Directory

Answer 5

This is what I use, cd into the project directory and do:

ndk-build NDK_PROJECT_PATH=.

Answer 6

-C worked for me.

You can also use the mac terminal to do this.
