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.

Custom categories should use the package name as a prefix, to ensure that they are unique.
