title: Where can I see the default styles.xml in Android?
body: <p>Where can I find the source code of the definition of the android default styles, such as <code>?android:attr/progressBarStyle</code>?</p>
  
  <p>I know that the Android repo is replicated in <a href="https://github.com/android">https://github.com/android</a> but... I just can't find the styles.xml, strings.xml, etc there!</p>
