Where can I find documentation when coding in Eclipse?

Then writing XML as manifest, how can I find documentation for things like intent-filter or action? Can I somehow display information on this in Eclipse without visiting developer.android.com lik开发者_如何学Pythone I can see the JavaDoc in Eclipse?

<activity android:name=".Activity1"
android:label="Activity1">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

In Eclipse just press Ctrl+Space and you will get descriptions of elements.

Just make sure you're opening your manifest with the Manifest editor (right click on manifest -> open with -> Android Manifest Editor). Anyway why not use the GUI editor? You have tips there as well.
