If you take a look at Android Settings manifest file and find activity section named "Settings$DataUsageSummaryActivity", it doesn't seem like it has an intent for being launched. Its intent filter has only one action tag(MAIN).
In Settings/AndroidManifest.xml,
<activity android:name="Settings$DataUsageSummaryActivity"
...>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="com.android.settings.SHORTCUT" />
</intent-filter>
...
</activity>
As you can see in this code, there is no custom action intent defined here.
