爱华网简述：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 matchingfilters.
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() andUri.getAuthority()获取authority.
DataPath: scheme and authority必须先匹配上 ntent. getData() andUri.getPath（），获取. 或者IntentFilter没有定义
Categories：all of the categories in the Intent match categoriesgiven 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。
