In this article, we will discuss some new improvements to the intent filter in Android 15
Major components
A UriRelativeFilterGroup contains a set of UriRelativeFilter objects that form a set of Intent matching rules that must be satisfied — [URL fragments, query params, etc.]
We can define these new rules in AndroidManifest file with the new <uri-relative-filter-group> tag
- With this tag, we can use
data tags with existing attributes as well as the new [android:fragment, android:query, android:allow]
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="https" />
<data android:host="developer.android.com" />
<uri-relative-filter-group android:allow="true">
<data android:pathPrefix="/samples" />
<data android:query="language=kotlin" />
</uri-relative-filter-group>
<uri-relative-filter-group android:allow="false">
<data android:pathPrefix="/reference" />
<data android:fragment="jetpack" />
</uri-relative-filter-group></intent-filter>
Implementation
In the AndroidManifest file, add intent-filter to the Activity tag to handle deep links 🔗
