When editing native JNI code in an Android project using theAndroid NDKyou may configure Eclipse to automatically rebuild your project when editing native code, just as it does for java. The below steps shows how to perform the necessary configuration (note that this requires revision 4 or later of the NDK - previous revisions does not contain the necessaryndk-buildbinary):

Start by right clicking on your android project (with JNI resources, and selectProperties. In the resulting dialog, choose theBuildersentry in the list to the left and press theNew...button:

A new dialog will open presenting a list of builder types. Select theProgramtype and press theOKbutton:

In theMaintab, fill in the following:

Name:

NDK Builder

Location:

/opt/android-ndk/ndk-build (or wherever your ndk-build binary is). You may use a variable as in ${system_property:user.home}/lib/android-ndk/ndk-build

Working Directory:

${workspace_loc:/hello-neon} (replace hello-neon with your project name. Press the Browse Workspace...button to select it graphically)

The result should look something like the below:

Now continue with the refresh tab. Make sure the two checkboxesRefresh resources upon completion.andRecursively include sub-foldersare checked. Choose theSpecific resourcesradio button and press theSpecify Resources...button:

Since the ndk-build process will generate files in the lib folder, we want Eclipse to discover changes made there without having to refresh manually. So select the lib folder in the project (create one if necessary) and press theFinishbutton:

Now skip theEnvironmenttab and go to the finalBuild Optionstab. Make sure theRun the builder: During auto buildscheckbox is checked.

Since the NDK build only needs to happen when editing files in thejnifolder, check that folder and press theFinishbutton.

Now finally pressOKin the builder configuration dialog - the new NDK builder should now be up and running. Try editing any file in thejnifolder and check that theConsoleview produces output from the build process:
