How to filter only specific URL with intent filter

You want to either use path, pathPrefix, or pathPattern, according to the docs here.

In your case, either pathPattern or pathPrefix will work,

pathPattern="mobile/*"

or

pathPrefix="mobile"

However, that does not explain why your filter is matching all URIs. it should be matching none since path does not understand "*". i suspect there is something added / missing from somewhere else in your code.

Try this:

<data android:host="gaapa.cz"
      android:pathprefix="mobile/"
      android:scheme="http" />
