Answer 1

Just saw this problem today. In my case actual problem was spaces inside path to project.

(yes, ndk-build will not compile your project if you have spaces inside folder name)

Answer 2

Same problem (in Windows 7) but the cause is different.

After searching in the Environment parameters, I've found the evil thing named "NDK_PROJECT_PATH" which has value is an invalid path.

Deleted it and things are working again ;)

Answer 3

In my case the problem was with white spaces in the project path. In such case, change the project path folders and import the project again.

Answer 4

I just installed Android-NDK and tried "ndk-build". I had exactly the same error. Here is how I beat it.

bash

export NDK_PROJECT_PATH={root_of_android_ndk}/samples/hello-jni

./ndk-build

This worked.

Answer 5

Details of the problem:

Android NDK: Your APP_BUILD_SCRIPT points to an unknown file: /jni/Android.mk ...: *** Android NDK: Aborting... . Stop. Usually this is not the path of your project, so the reason for this error is that ndk could not find the correct Android.mk file path. solution:

Add NDK_PROJECT_PATH to "./" in the environment variable, the purpose is to tell the NDK that the jni currently to be compiled is located in the directory where the project is located.
