Removing Native Support from Android Projects in Eclipse

Adding native support (right-click project for context menu -> Android Tools -> Add Native Support...) for the NDK to a normal Eclipse Android project is easily enough done and no doubt an oft task for some, but the reverse is something I found isn't on the menu (i.e. no "Remove Native Support").

After a little bit of playing around these are the steps I figured out. I'm currently using Eclipse Helios with Android NDK r6b.

1. Remove the lib and jni folders from your project and delete the contents of the bin folder.
2. From Windows Explorer remove the .cproject file and .externalToolBuilders folder if either of them exist in your project's root folder.
3. Edit the .project file in your project's root folder and remove any lines that match the following.
   Look for the following in between the buildSpec tags:
   

   org.eclipse.cdt.managedbuilder.core.genmakebuilder
      clean,full,incremental,
      
       
        ?children?
        ?name?=outputEntries\|?children?=?name?=entry\\\\\\\|\\\|\||
       
       
        ?name?
        
       
       
        org.eclipse.cdt.make.core.append_environment
        true
       
       
        org.eclipse.cdt.make.core.buildArguments
        E:\dev\android\android-ndk-r6b\ndk-build
       
       
        org.eclipse.cdt.make.core.buildCommand
        bash
       
       
        org.eclipse.cdt.make.core.cleanBuildTarget
        clean
       
       
        org.eclipse.cdt.make.core.contents
        org.eclipse.cdt.make.core.activeConfigSettings
       
       
        org.eclipse.cdt.make.core.enableAutoBuild
        false
       
       
        org.eclipse.cdt.make.core.enableCleanBuild
        true
       
       
        org.eclipse.cdt.make.core.enableFullBuild
        true
       
       
        org.eclipse.cdt.make.core.fullBuildTarget
        V=1
       
       
        org.eclipse.cdt.make.core.stopOnError
        true
       
       
        org.eclipse.cdt.make.core.useDefaultBuildCmd
        false
       
      
     
   

   and
   

   
      org.eclipse.cdt.managedbuilder.core.ScannerConfigBuilder
      full,incremental,
      
      
     
   

   Look for the following in between the natures tags:

   org.eclipse.cdt.core.cnature
     org.eclipse.cdt.core.ccnature
     org.eclipse.cdt.managedbuilder.core.managedBuildNature
     org.eclipse.cdt.managedbuilder.core.ScannerConfigNature
   

4. Delete your project from your Eclipse workspace (but don't select the delete the files on disk option) and then re-import from the same directory.

All done.
