source.android.com から Android 4.3 のソースコードをダウンロードし、アプリ DeskClock を見つけてコンパイルしたいのですが、問題があります...
DeskClock.java では、android.support.v13.app.FragmentPagerAdapter をインポートし、android.support.v4.view.ViewPager をインポートしますが、それは別の jar ですか?
これはソースコードです：

私はv13を入手できるandroid.support.v4しか持っていませんか? v4 と v13 を同時にインポートする必要があるのはなぜですか?
コードを変更せずにコンパイルを渡すにはどうすればよいですか?
