IntentFilter

IntentFilter
简述：结构化描述intent匹配的信息。包含：action，categories and data(via type,scheme ,path),还有priority, to order multiple matching filters.
       IntentFilter 中如果action为空，则视为通配符，如果type为空，则intent必须不设type，否则匹配不上。
       data被分为3个属性：type,scheme,authority/path 任何设置的属性intent必须匹配上。
                           设置了scheme 而没设type,则intent也必须类似，不能设置type，也不能是content: URI.
                           设置了type而没设scheme：将匹配上没有URI的intent，或者content:,file:的uri。
                           设置了authority:必须指定一个或多个相关联的schemes
                           设置了path：唏嘘指定一个或多个相关联的schemes
       匹配规则：
           IntentFilter 匹配Intent的上的条件：
           Action : 值相同 ,或则IntentFilter未指定action.
           DataType:. 系统通过调用Intent.resolve(ContentResolver)获取type，通配符*
                     在Intent/IntentFilter的MIME type中使用，区分大小写
           DataScheme：系统通过调用Intent. getData() and Uri.getScheme())获取scheme, 区分大小写
           DataAuthority:必须有一个dataScheme匹配上且authority值匹配上，或者IntentFilter没有定义。Intent. getData() and Uri.getAuthority()获取authority.
           DataPath: scheme and authority必须先匹配上 ntent. getData() and Uri.getPath（），获取. 或者IntentFilter没有定义
           Categories：all of the categories in the Intent match categories given in the filter 多余的Categorie，不影响intent匹配，如果IntentFilter
                  没有指定Categorie，则只能匹配上没有Categorie的intent。
