With Android, the application opens when links xml, rss or atom are selected in Safari.
To do this, I use the Cordovan-webintent plugin, and I add following case in AndroidManifest.xml:
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" />
<data android:mimeType="text/xml" />
<data android:mimeType="application/rss+xml" />
<data android:mimeType="application/atom+xml" />
<data android:mimeType="application/xml" />
</intent-filter>
And I get the file in the application with the Cordovan-webintent plugin
I can not find a solution to do the same with IOS, ie open a file with the app when the "mine type" is met.
URL scheme does not seem to fit the need.
