MimeTypeFilter
class MimeTypeFilter
Provides utility methods for matching MIME type filters used in ContentProvider.
Wildcards are allowed only instead of the entire type or subtype with a tree prefix. Eg. image\/*, *\/* is a valid filter and will match image/jpeg, but image/j* is invalid and it will not match image/jpeg. Suffixes and parameters are not supported, and they are treated as part of the subtype during matching. Neither type nor subtype can be empty.
Note: MIME type 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, or use normalizeMimeType to ensure that they are converted to lower case.
MIME types can be null or ill-formatted. In such case they won't match anything.
MIME type filters must be correctly formatted, or an exception will be thrown.
