- description:
- Specifies the types of intents that an activity, service, or broadcast
receiver can respond to. An intent filter declares the capabilities of its
parent component — what an activity or service can do and what types
of broadcasts a receiver can handle. It opens the component to receiving
intents of the advertised type, while filtering out those that are not
meaningful for the component.
Most of the contents of the filter are described by its
<action> ,
<category> , and
<data> subelements.
For a more detailed discussion of filters, see the separate
Intents
and Intent Filters document, as well as the
Intents Filters
section in the introduction.
- attributes:
android:icon
- An icon that represents the parent activity, service, or broadcast
receiver when that component is presented to the user as having the
capability described by the filter.
This attribute must be set as a reference to a drawable resource
containing the image definition. The default value is the icon set
by the parent component's icon attribute. If the parent
does not specify an icon, the default is the icon set by the
<application> element.
For more on intent filter icons, see
Icons and Labels
in the introduction.
android:label
- A user-readable label for the parent component. This label, rather than
the one set by the parent component, is used when the component is presented
to the user as having the capability described by the filter.
The label should be set as a reference to a string resource, so that
it can be localized like other strings in the user interface.
However, as a convenience while you're developing the application,
it can also be set as a raw string.
The default value is the label set by the parent component. If the
parent does not specify a label, the default is the label set by the
<application> element's
label attribute.
For more on intent filter labels, see
Icons and Labels
in the introduction.
android:priority
- The priority that should be given to the parent component with regard
to handling intents of the type described by the filter. This attribute has
meaning for both activities and broadcast receivers:
Use this attribute only if you really need to impose a specific order in
which the broadcasts are received, or want to force Android to prefer
one activity over others.
The value must be an integer, such as "100 ". Higher numbers have a
higher priority.
