Use C with Android ndk

Question

I am trying to develop a Android project that makes a simple call from Java code to native C code. I refer this link for my guidance: http://mobile.tutsplus.com/tutorials/android/ndk-tutorial/

when I am compiling the native.c using

:ndk-build

it shows:

ndk-build command not found

Could anyone give the reason for this?

thanks ,

Answer 1

From your question description, i assume that your path is not set. You need to set your NDK path in your environment variable.

for more information you can visit following site.

Answer 2

From my part, I try to set the path by several ways:

• complete the /etc/paths file with the ndk directory and restart the Mac
• use the shell command: export NDK_HOME=/Users/myself/directory1/directory2/android-ndk-r9
• use the Eclipse menu: Eclipse > Preferences > Android > NDK

However I always get the error message: "ndk-build command not found"

Finally I solved the issue by setting the path directly in the Build command field of the C/C++ Build Properties dialog box: /Users/myself/directory1/directory2/android-ndk-r9/ndk-build I know it's not a proper solution but it works for me for now.
