<category>

syntax:
<category android:name="string" />
contained in:
<intent-filter>
description:
Adds a category name to an intent filter. See Intents and Intent Filters for details on intent filters and the role of category specifications within a filter.
attributes:
android:name
The name of the category. Standard categories are defined in the Intent class as CATEGORY_name constants. The name assigned here can be derived from those constants by prefixing "android.intent.category." to the name that follows CATEGORY_. For example, the string value for CATEGORY_LAUNCHER is "android.intent.category.LAUNCHER".

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 it in your intent filter, no implicit intents will resolve to your activity.
