More than one intent-filter with category DEFAULT

Read the documentation but unclear as to the purpose of the DEAFAULT category in the manifest. Is it possible to have more than 1 intent-filter with the DEFAULT category attribute in the same manifest?

Yes it is possible to have more than one. From the documentation here is why you would need the default category:

*Note: In order to receive implicit intents, you must include the CATEGORY_DEFAULT category in the intent filter. The methods startActivity() and startActivityForResult() treat all intents as if they declared the CATEGORY_DEFAULT category. If you do not declare this category in your intent filter, no implicit intents will resolve to your activity.* - http://developer.android.com/guide/components/intents-filters.html

Example of having more than one intent filter with default category:

            <intent-filter>
                <action android:name="android.intent.action.CREATE_SHORTCUT"/>
                <category android:name="android.intent.category.DEFAULT"/>
            </intent-filter>

            <intent-filter>
                <action android:name="android.nfc.action.NDEF_DISCOVERED"/>
                <category android:name="android.intent.category.DEFAULT"/>
                <data android:scheme="myscheme"/>
            </intent-filter>

Is it possible to have more than 1 intent-filter with the DEFAULT category attribute in the same manifest?

Sure. Most activities that have an <intent-filter> will support the DEFAULT category, as that category is automatically added to an Intent used with startActivity() if there is no other category on the Intent already.

For example, in the manifest for the AOSP Music app, you can see a variety of <activity> elements, with and without <intent-filter> elements. Those that have <intent-filter> may or may not use DEFAULT.
