It's not possible to launch this exact screen (no API for that).

However you can easily recreate a similar screen yourself.

This code lists the activities available in the launcher:

final PackageManager packageManager = getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> resInfos = packageManager.queryIntentActivities(intent, 0);
//using hashset so that there will be no duplicate packages, 
//if no duplicate packages then there will be no duplicate apps
HashSet<String> packageNames = new HashSet<String>(0);
List<ApplicationInfo> appInfos = new ArrayList<ApplicationInfo>(0);

//getting package names and adding them to the hashset
for(ResolveInfo resolveInfo : resInfos) {
    packageNames.add(resolveInfo.activityInfo.packageName);
}

//now we have unique packages in the hashset, so get their application infos
//and add them to the arraylist
for(String packageName : packageNames) {
    try {
        appInfos.add(packageManager.getApplicationInfo(packageName, PackageManager.GET_META_DATA));
    } catch (NameNotFoundException e) {
        //Do Nothing
    }
}

//to sort the list of apps by their names
Collections.sort(appInfos, new ApplicationInfo.DisplayNameComparator(packageManager));

Then show the elements in appInfos into a WearableListView.
