Dropbox login crash on Android 13 with targetSdk 33

Hi, I’ve lifted my app to targetSdk 33. The Dropbox login flow crashes on my Android 13 device when pressing “Allow” in the “grant access” dialog in the Dropbox app (i.e. throwing ActivityNotFound when trying to call back to my app). Very likely root cause: “Intent filters block non-matching intents” change introduced with Android 13 SDK 33. It works fine when reverting my app to targetSdk 31.

Are you aware of this issue? I assume this needs a patch on your side (?)

perfect. yes this works. many thanks. (and yes, my manifest entry is like in the example app).

recap for those stumbling over the same problem and seeing this - the second intent-filter needs to be added to manifest when targeting Android 13:

        <activity
            android:name="com.dropbox.core.android.AuthActivity"
            android:exported="true"
            android:configChanges="orientation|keyboard"
            android:launchMode="singleTask">
            <intent-filter>
                <!-- Change this to be db- followed by your app key -->
                <data android:scheme="db-${dropboxKey}" />
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.BROWSABLE" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
            <!-- for Android 13 -->
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

Yes, this is a valid as a workaround until you’re confident your users are running a newer version of Dropbox.
