<action>
<Action Android: name = "String" />
   Action

   2. For operations defined, preferably an application package name prefixed in order to ensure uniqueness

<data>
<data android:scheme="string"
      android:host="string"
      android:port="string"
      android:path="string"
      android:pathPattern="string"
      android:pathPrefix="string"
      android:mimeType="string" />

URI format: [scheme:] [// host : port] [path]
eg: http: //192.168.1.1: 8080 / test / aabb

scheme:
   scheme part of the URI. This is the URI specified minimum basic properties; must be at least one scheme property to filter, otherwise the other URI properties did not make sense.
   The above example is http scheme.
host:
   such as the above is 192.168.1.1 Host
Port:
   such is above 8080 Port
path:
   to match the full path: the above example, / test / aabb is path
pathPattern:
   use expressions to match the whole path.
pathPrefix:
   to match the beginning of the path: the above example, the set pathPrefix / test can be carried out to match the
mimeType:
   Data Type
   Note: the different formal RFC MIME type, MIME type matching Android framework is case-sensitive . Therefore, you should always use lowercase letters specified MIME type.
   mimeType also be used to match the Intent. For example, when you use Intent.setType ( "text / plain") ,
   then the system will match to all registered android: mimeType = "text / plain " of Activity,
   It should be noted that very Intent.setType (), Intent. setData, Intent.setDataAndType () these three methods!
 
   After calling mimeType setType provided, then data is set to null;
   setting data after setData call, then mimeType set to null;
   will be provided with data while the rear setDataAndType mimeType call.

Match symbol:
   "*" to match zero or more, such as: "A *" match "A", "AA", "AAA" ...
   "." Matches any character, such as:. " "match" A "," B "," C "...
    . Therefore," * "matches any character is 0 or more, such as:". * html "match" abchtml "," chtml " , "html", "sdf.html" ...
escape:
    because when read Xml when the "\" is treated as an escape character (when pathPattern before it is used as an escape),
    so there needs twice escaped, read Xml is once again in use is in pathPattern.
Such as: "*" this character should be written as "\\ *", "\" This character should be written as "\\."
