Answer 1

If you use Windows 7, you can set it like this:

1. Right click on "My Computer"
2. Click on "Properties"
3. Click on "Advanced System"
4. Make a new variable NDKROOT
5. Change the value to your NDK path
6. Restart Eclipse
7. Click "OK"

Answer 2

Try the following steps:

1. Head to the project's properties. If you're using Windows, the shortcut is Alt + Enter; or simply right-click the project name to find its properties.

2. Go to the C/C++ Build section; under Builder Settings tab in Build command: text box you're likely to find something similar to that below, if it's empty then type in the similar text - namely: ${NDKROOT}/ndk-build.cmd where NDKROOT, as its name implies, refers to the path where your NDK root folder exists.

3. Now you must inform eclipse what NDKROOT equates to; as in, where is the NDK root path. You can do this by heading to (in your project's properties) C/C++ Build > Environment > press Add…

4. Now add your environment variable named NDKROOT (the Name) with the relevant path (Value). Note that you're to repeat this per NDK project. You would get a window similar to that below.

5. Press OK to the New variable input window and then OK again to the properties window.
