IntentFilter

extends Object
implements Parcelable

java.lang.Object
↳	android.content.IntentFilter

Class Overview

Structured description of Intent values to be matched. An IntentFilter can match against actions, categories, and data (either via its type, scheme, and/or path) in an Intent. It also includes a "priority" value which is used to order multiple matching filters.

IntentFilter objects are often created in XML as part of a package's AndroidManifest.xml file, using intent-filter tags.

There are three Intent characteristics you can filter on: the action, data, and categories. For each of these characteristics you can provide multiple possible matching values (via addAction(String), addDataType(String), addDataScheme(String) addDataAuthority(String, String), addDataPath(String, int), and addCategory(String), respectively). For actions, the field will not be tested if no values have been given (treating it as a wildcard); if no data characteristics are specified, however, then the filter will only match intents that contain no data.

The data characteristic is itself divided into three attributes: type, scheme, authority, and path. Any that are specified must match the contents of the Intent. If you specify a scheme but no type, only Intent that does not have a type (such as mailto:) will match; a content: URI will never match because they always have a MIME type that is supplied by their content provider. Specifying a type with no scheme has somewhat special meaning: it will match either an Intent with no URI field, or an Intent with a content: or file: URI. If you specify neither, then only an Intent with no data or type will match. To specify an authority, you must also specify one or more schemes that it is associated with. To specify a path, you also must specify both one or more authorities and one or more schemes it is associated with.

A match is based on the following rules. Note that for an IntentFilter to match an Intent, three conditions must hold: the action and category must match, and the data (both the data type and data scheme+authority+path if specified) must match.

Action matches if any of the given values match the Intent action, or if no actions were specified in the filter.

Data Type matches if any of the given values match the Intent type. The Intent type is determined by calling resolveType(ContentResolver). A wildcard can be used for the MIME sub-type, in both the Intent and IntentFilter, so that the type "audio/*" will match "audio/mpeg", "audio/aiff", "audio/*", etc. Note that MIME type matching here is case sensitive, unlike formal RFC MIME types! You should thus always use lower case letters for your MIME types.

Data Scheme matches if any of the given values match the Intent data's scheme. The Intent scheme is determined by calling getData() and getScheme() on that URI. Note that scheme matching here is case sensitive, unlike formal RFC schemes! You should thus always use lower case letters for your schemes.

Data Authority matches if any of the given values match the Intent's data authority and one of the data scheme's in the filter has matched the Intent, or no authories were supplied in the filter. The Intent authority is determined by calling getData() and getAuthority() on that URI. Note that authority matching here is case sensitive, unlike formal RFC host names! You should thus always use lower case letters for your authority.

Data Path matches if any of the given values match the Intent's data path and both a scheme and authority in the filter has matched against the Intent, or no paths were supplied in the filter. The Intent authority is determined by calling getData() and getPath() on that URI.

Categories match if all of the categories in the Intent match categories given in the filter. Extra categories in the filter that are not in the Intent will not cause the match to fail. Note that unlike the action, an IntentFilter with no categories will only match an Intent that does not have any categories.

Public Constructors

public IntentFilter ()

Since: API Level 1

New empty IntentFilter.

public IntentFilter (String action)

Since: API Level 1

New IntentFilter that matches a single action with no data. If no data characteristics are subsequently specified, then the filter will only match intents that contain no data.

Parameters

action	The action to match, i.e. Intent.ACTION_MAIN.

public IntentFilter (String action, String dataType)

Since: API Level 1

New IntentFilter that matches a single action and data type.

Note: MIME type matching in the Android framework is case-sensitive, unlike formal RFC MIME types. As a result, you should always write your MIME types with lower case letters, and any MIME types you receive from outside of Android should be converted to lower case before supplying them here.

Throws IntentFilter.MalformedMimeTypeException if the given MIME type is not syntactically correct.

Parameters

action	The action to match, i.e. Intent.ACTION_VIEW.
dataType	The type to match, i.e. "vnd.android.cursor.dir/person".

Throws

IntentFilter.MalformedMimeTypeException

public IntentFilter (IntentFilter o)

Since: API Level 1

New IntentFilter containing a copy of an existing filter.

Parameters

o	The original filter to copy.

Public Methods

public final Iterator<String> actionsIterator ()

Since: API Level 1

Return an iterator over the filter's actions. If there are no actions, returns null.

public final void addAction (String action)

Since: API Level 1

Add a new Intent action to match against. If any actions are included in the filter, then an Intent's action must be one of those values for it to match. If no actions are included, the Intent action is ignored.

Parameters

action	Name of the action to match, i.e. Intent.ACTION_VIEW.

public final void addCategory (String category)

Since: API Level 1

Add a new Intent category to match against. The semantics of categories is the opposite of actions -- an Intent includes the categories that it requires, all of which must be included in the filter in order to match. In other words, adding a category to the filter has no impact on matching unless that category is specified in the intent.

Parameters

category	Name of category to match, i.e. Intent.CATEGORY_EMBED.

public final void addDataAuthority (String host, String port)

Since: API Level 1

Add a new Intent data authority to match against. The filter must include one or more schemes (via addDataScheme(String)) for the authority to be considered. If any authorities are included in the filter, then an Intent's data must match one of them. If no authorities are included, then only the scheme must match.

Note: host name in the Android framework is case-sensitive, unlike formal RFC host names. As a result, you should always write your host names with lower case letters, and any host names you receive from outside of Android should be converted to lower case before supplying them here.

Parameters

host	The host part of the authority to match. May start with a single '*' to wildcard the front of the host name.
port	Optional port part of the authority to match. If null, any port is allowed.

public final void addDataPath (String path, int type)

Since: API Level 1

Add a new Intent data oath to match against. The filter must include one or more schemes (via addDataScheme(String)) and one or more authorities (via addDataAuthority(String, String)) for the path to be considered. If any paths are included in the filter, then an Intent's data must match one of them. If no paths are included, then only the scheme/authority must match.

The path given here can either be a literal that must directly match or match against a prefix, or it can be a simple globbing pattern. If the latter, you can use '*' anywhere in the pattern to match zero or more instances of the previous character, '.' as a wildcard to match any character, and '\' to escape the next character.

Parameters

path	Either a raw string that must exactly match the file path, or a simple pattern, depending on `type`.
type	Determines how `path` will be compared to determine a match: either PATTERN_LITERAL, PATTERN_PREFIX, or PATTERN_SIMPLE_GLOB.

public final void addDataScheme (String scheme)

Since: API Level 1

Add a new Intent data scheme to match against. If any schemes are included in the filter, then an Intent's data must be either one of these schemes or a matching data type. If no schemes are included, then an Intent will match only if it includes no data.

Note: scheme matching in the Android framework is case-sensitive, unlike formal RFC schemes. As a result, you should always write your schemes with lower case letters, and any schemes you receive from outside of Android should be converted to lower case before supplying them here.

Parameters

scheme	Name of the scheme to match, i.e. "http".

public final void addDataType (String type)

Since: API Level 1

Add a new Intent data type to match against. If any types are included in the filter, then an Intent's data must be either one of these types or a matching scheme. If no data types are included, then an Intent will only match if it specifies no data.

Note: MIME type matching in the Android framework is case-sensitive, unlike formal RFC MIME types. As a result, you should always write your MIME types with lower case letters, and any MIME types you receive from outside of Android should be converted to lower case before supplying them here.

Throws IntentFilter.MalformedMimeTypeException if the given MIME type is not syntactically correct.

Parameters

type	Name of the data type to match, i.e. "vnd.android.cursor.dir/person".

public final int match (String action, String type, String scheme, Uri data, Set<String> categories, String logTag)

Since: API Level 1

Test whether this filter matches the given intent data. A match is only successful if the actions and categories in the Intent match against the filter, as described in IntentFilter; in that case, the match result returned will be as per matchData(String, String, Uri).

Parameters

action	The intent action to match against (Intent.getAction).
type	The intent type to match against (Intent.resolveType()).
scheme	The data scheme to match against (Intent.getScheme()).
data	The data URI to match against (Intent.getData()).
categories	The categories to match against (Intent.getCategories()).
logTag	Tag to use in debugging messages.

Returns

Returns either a valid match constant (a combination of MATCH_CATEGORY_MASK and MATCH_ADJUSTMENT_MASK), or one of the error codes NO_MATCH_TYPE if the type didn't match, NO_MATCH_DATA if the scheme/path didn't match, if the action didn't match, or {@link #NO_MATCH_CATEGORY if one or more categories didn't match.

public final int match (ContentResolver resolver, Intent intent, boolean resolve, String logTag)

Since: API Level 1

Test whether this filter matches the given intent.

Parameters

intent	The Intent to compare against.
resolve	If true, the intent's type will be resolved by calling Intent.resolveType(); otherwise a simple match against Intent.type will be performed.
logTag	Tag to use in debugging messages.

Returns

Returns either a valid match constant (a combination of MATCH_CATEGORY_MASK and MATCH_ADJUSTMENT_MASK), or one of the error codes NO_MATCH_TYPE if the type didn't match, NO_MATCH_DATA if the scheme/path didn't match, if the action didn't match, or {@link #NO_MATCH_CATEGORY if one or more categories didn't match.How well the filter matches. Negative if it doesn't match, zero or positive positive value if it does with a higher value representing a better match.

public final boolean matchAction (String action)

Since: API Level 1

Match this filter against an Intent's action. If the filter does not specify any actions, the match will always fail.

Parameters

action	The desired action to look for.

Returns

True if the action is listed in the filter or the filter does not specify any actions.

public final String matchCategories (Set<String> categories)

Since: API Level 1

Match this filter against an Intent's categories. Each category in the Intent must be specified by the filter; if any are not in the filter, the match fails.

Parameters

categories	The categories included in the intent, as returned by Intent.getCategories().

Returns

If all categories match (success), null; else the name of the first category that didn't match.

public final int matchData (String type, String scheme, Uri data)

Since: API Level 1

Match this filter against an Intent's data (type, scheme and path). If the filter does not specify any types and does not specify any schemes/paths, the match will only succeed if the intent does not also specify a type or data.

Be aware that to match against an authority, you must also specify a base scheme the authority is in. To match against a data path, both a scheme and authority must be specified. If the filter does not specify any types or schemes that it matches against, it is considered to be empty (any authority or data path given is ignored, as if it were empty as well).

Note: MIME type, Uri scheme, and host name matching in the Android framework is case-sensitive, unlike the formal RFC definitions. As a result, you should always write these elements with lower case letters, and normalize any MIME types or Uris you receive from outside of Android to ensure these elements are lower case before supplying them here.

Parameters

type	The desired data type to look for, as returned by Intent.resolveType().
scheme	The desired data scheme to look for, as returned by Intent.getScheme().
data	The full data string to match against, as supplied in Intent.data.

Returns

Returns either a valid match constant (a combination of MATCH_CATEGORY_MASK and MATCH_ADJUSTMENT_MASK), or one of the error codes NO_MATCH_TYPE if the type didn't match or NO_MATCH_DATA if the scheme/path didn't match.

public final int matchDataAuthority (Uri data)

Since: API Level 1

Match this intent filter against the given Intent data. This ignores the data scheme -- unlike matchData(String, String, Uri), the authority will match regardless of whether there is a matching scheme.

Parameters

data	The data whose authority is being looked for.

Returns

Returns either MATCH_CATEGORY_HOST, MATCH_CATEGORY_PORT, NO_MATCH_DATA.

public final Iterator<PatternMatcher> pathsIterator ()

Since: API Level 1
