title: AOSP method names endings
body: <p>I'm reading code in the Android Open Source Project, and I see methods with method names that have funny endings, like this:
  addSharedUserLPw() (in com.android.server.pm.Settings) 
  installPackageLI() (in com.android.server.pm.PackageManagerService)</p>
  
  <p>I'm sure the LPw and LI etc. have meanings, I'm just not sure how to figure them out. Can anyone provide any more information on this?</p>
