Setting the correct intent filters in your manifest will allow it be prompt you to use it as a replacement:
<activity android:name="Home"
...
android:launchMode="singleInstance"
android:stateNotNeeded="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.HOME"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
See the Intents and Intent Filters documentation from Google.
