title: In AOSP, where is the ServiceManager implemented
body: <p>In the <code>IServiceManager.cpp</code> file, I see the <code>BnServiceManager::onTransact</code> function definition.</p>
  
  <p>Inside that function, there is a call to "<code>addService</code>", "<code>listServices</code>" etc. </p>
  
  <p>I couldn't find the implementation for those functions (which are declared under IServiceManager).</p>
  
  <p>Can somebody please tell me, where to find the implementation of BnServiceManager.</p>
