title: gradle difference between packageDebug and assembleDebug
body: <p>Both <code>gradlew packageDebug</code> and <code>gradlew assembleDebug</code> will create my APK.  <code>assembleDebug</code> appears to rely on <code>packageDebug</code>, so what else is it doing for me?  Is there some reason I should be using one or the other?</p>
