如何使应用程序的启动图标运行首选项活动？

Question

I would like an app's launch icon run the app's preferences activity (as it has no Activities, only a Service).

The preferences are defined in res/xml/preferences.xml.

Please help me regarding this.

Answer 1

you need to create an activity for your preference (PreferenceActivity), add that activity in your manifest and provide appropriate intent-filters as shown below to run through launcher:

<activity android:name=".MyPreferenceActivity" android:label="Preferences" android:noHistory="true">
    <intent-filter>
         <action android:name="android.intent.action.MAIN" />
         <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
