Setting up Automatic NDK Builds in Eclipse

转载地址：http://mobilepearls.com/labs/ndk-builder-in-eclipse/

When editing native JNI code in an Android project using the Android NDK you 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 necessary 

ndk-build

 binary):

Start by right clicking on your android project (named hello-neon in the below screenshots) with JNI resources, and select 

Properties

. In the resulting dialog, choose the 

Builders

 entry in the list to the left and press the 

New...

 button:



A new dialog will open presenting a list of builder types. Select the 

Program

 type and press the 

OK

 button:



In the 

Main

 tab, fill in the following:
Name:NDK BuilderLocation:/opt/android-ndk/ndk-build (or wherever your ndk-build binary is). You may use a variable as in ${system_property:user.home}/lib/android-ndk/ndk-buildWorking Directory:${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 checkboxes 

Refresh resources upon completion.

 and 

Recursively include sub-folders

 are checked. Choose the 

Specific resources

 radio button and press the 

Specify
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 the 

Finish

 button:



Now skip the 

Environment

 tab and go to the final 

Build Options

 tab. Make sure the 

Run the builder: During auto builds

 checkbox is checked.



Since the NDK build only needs to happen when editing files in the 

jni

 folder, check that folder and press the 

Finish

 button.



Now finally press 

OK

 in the builder configuration dialog - the new NDK builder should now be up and running. Try editing any file in the 

jni

 folder and check that the 

Console

 view produces output from the build process:
