Dolphin supports a special intent filter for Add-ons that have a Preference activity. This intent allows the Dolphin browser to display an option that takes the user directly to the Preference activity. For Add-ons that have a Preference page, the use of this intent is recommended for ease of development and a polished, consistent user interface.
The Preference activity is declared in the Add-on’s Android manifest as shown in this example:
<activity android:name="PreferenceActivity"> <intent-filter> <action android:name="com.dolphin.browser.action.preference"/> </intent-filter> </activity>
