Tech Blog: Launch an App Using A URL

First of all, you need to have a clear idea about the intent filters and the data section.

Adds a data specification to an intent filter. The specification can be just a data type, just a URI, or both a data type and a URI. A URI is specified by separate attributes for each of its parts:

<scheme>://<host>:<port>[<path>|<pathPrefix>|<pathPattern>]

These attributes that specify the URL format are optional, but also mutually dependent:

  • You should have to specify the scheme for the intent filter otherwise, all the other URI attributes are ignored.
  • You should have to specify the host for the intent filter otherwise, port and other attributes get ignored.

All the <data> elements contained within the same <intent-filter> element contribute to the same filter. So, for example, the following filter specification,

<intent-filter . . . >
    <data android:scheme="something" android:host="project.example.com" />
    . . .
</intent-filter>

is equivalent to this one:

<intent-filter . . . >
    <data android:scheme="something" />
    <data android:host="project.example.com" />
    . . .
</intent-filter>
You can place any number of <data> elements inside an <intent-filter> to give it multiple data options. None of its attributes have default values.solution
