Dual apps in Android launcher

Question

I'm creating an Android launcher. Some users have dual apps set up, eg for work (like WhatsApp with a dual sim). Now, I want to display both the default and dual instance of these apps , but only the default instance is showing (which makes sense given that I store all apps in a HashMap by their packageNames and the packageName is unique per app). I've tried searching for a solution to find the dual instance of an app, but came up empty.

I'm querying for packages through the PackageManager 's queryIntentActivities :

PackageManager packageManager = context.getPackageManager();
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> allActivities = packageManager.queryIntentActivities(mainIntent, 0);

Then I retrieve the packageName from the ResolveInfo of all activities and add it to the list of apps, if it wasn't in there already. How can I find out whether an app has a second instance which should be displayed in the launcher?

It looks like this dual app feature is currently not supported for third-party launchers.

A solution we're proposing to users is to download an app like Dual Apps , Parallel Space or any other app that helps with accessing dual accounts from a different SIM.

Hopefully in the future, third party launchers will also be able to use this dual app feature by themselves.
