title: Building a particular module in the android source code
body: <p>I am working on an android source code which I have downloaded from source.android.com.</p>
  
  <p>After a full build I went through this site <a href="http://elinux.org/Android_Build_System" rel="noreferrer">http://elinux.org/Android_Build_System</a> which explains the android build system.</p>
  
  <p>When I make changes in external/webkit code and build it with </p>
  
  <p><code>make -j4 libwebcore</code> it compiles the corresponding file and updates the libwebcore.so, and it save me a lot of time.
  The same thing is applied to applications and also for building apks.</p>
  
  <p>The problem arises when I make changes in the framework and give the command as
  <code>make -j4 framework</code>  its not compiling the corresponding files.
  Can any one help me!</p>
