Question

I’m building a home screen application for android and I’d like to disable (temporary) the default home screen (TwLauncher) or whatever app is running.

Is there any way to accomplish this?

You can’t disable other homescreens, but you can register your app as a homescreen by adding the appropriate intent-filters to your manifest:

<activity android:name="Home"  
        android:theme="@style/Theme"  
        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>

Different homescreens can exists concurrently, the user ultimately decides which homescreen he wants to set as his default homescreen manually.
