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. If the filter does not specify any schemes, it will implicitly match intents with no scheme, or the schemes "content:" or "file:" (basically performing a MIME-type only match). If the filter does not specify any MIME types, the Intent also must not specify a MIME type.
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.
