Your application has registered intent filters for handling intents of the http
scheme.
There's an example of building a custom browser on Lars Vogel's blog, which boils down to:
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".BrowserActivitiy"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="http"/>
</intent-filter>
</activity>
</application>
If you wish to disable this behavior, remove the <intent-filter>
tag from your activity.
