Your APP_BUILD_SCRIPT points to an unknown file using Android ndk-build

Question

I get the following error while trying to compile an Android NDK project:

ndk-build 
Android NDK: Your APP_BUILD_SCRIPT points to an unknown file: /home/lamb         


        

Answer 1

Inside Android.mk file, you give the path where the jni folder loacted... in your case ARTOOLKIT_DIR :=/home/lambergar/work/APIExample/

Answer 2

For me, deleted the .gradle and app/.externalNativeBuild directories and it worked.

Answer 3

You need to set the env variable NDK_PROJECT_PATH to the root of the project you are building. The root of your NDK project will typically contain the ./jni directory.

export NDK_PROJECT_PATH={root_of_project}

If your JNI code is in a library, then set NDK_PROJECT_PATH to the library project.

Answer 4

I just had the same problem. I fixed it by creating a Application.mk in $NDK/apps/ndktestapp with following content:

APP_PROJECT_PATH := /cygdrive/c/workspace/MyApp

and then calling

make APP=ndktestapp

from the NDK-Root. Hope that helps.

Answer 5

as the same as @phavens, i think that only wrong with the word Android.mk and android.mk file, just spent for 5 minutes .. hehe

Answer 6

Just spent an hour or two trying to figure this one out. Many, many people have had this problem. But as I found out I actually did not have a file name Android.mk it was named Andriod.mk and that was enough to cause me a lot of trouble. Sorry about my original rant but that was the whole problem in the end. I suggest if you have this problem you should check everything until you find something wrong.

This fixed me right up. Thanks guys you put me on the right track anyway.
