Breaking change

The RedirectUriReceiverActivity intent-filter must now be declared in the consuming app's AndroidManifest.xml. The library no longer provides it automatically.

Consuming apps must add the following to their manifest:

<activity
    android:name="com.spotify.sdk.android.auth.browser.RedirectUriReceiverActivity"
    android:exported="true">
    <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="your-redirect-scheme"
            android:host="your-redirect-host"
            android:pathPattern="your-path-pattern"/>
    </intent-filter>
</activity>

If your redirect URI uses https://, add android:autoVerify="true" to the <intent-filter>.

A runtime check in AuthorizationClient.authorize() and AuthorizationClient.openLoginInBrowser() throws IllegalStateException if the intent-filter is missing.

See full migration instructions in the README.

Why

• New apps published on Google Play need to target SDK version 35
• AGP 8.x AAPT rejects unresolved ${redirectPathPattern} manifest placeholders in library builds — moving the intent-filter to the consuming app resolves this without workarounds

Test plan

• Full ./gradlew build passes (290 tasks, all unit tests green)
• Verified runtime check crashes when intent-filter is missing
• Verified runtime check passes when intent-filter is present
• Verified AAR manifest has no baked-in placeholder values
• Verify sample app auth flow on API 35 device/emulator (Custom Tab, not plain browser)
