Answer 1

Starting from Android O, this is the way to create a shortcut:

if (ShortcutManagerCompat.isRequestPinShortcutSupported(context)) {
    final ShortcutManager shortcutManager = getSystemService(ShortcutManager.class);

    ShortcutInfo pinShortcutInfo = new ShortcutInfo.Builder(context, shortcutId)
            .setIcon(Icon.createWithResource(context, R.mipmap.ic_launcher))
            .setShortLabel(label)
            .setIntent(new Intent(context, MainActivity.class).setAction(Intent.ACTION_MAIN))
            .build();
    shortcutManager.requestPinShortcut(pinShortcutInfo, null);
}

It has a lot of limitations, sadly:

1. Requires the user to accept adding it.
2. Can't be added/removed in the background.
3. Won't be removed if the targeted app is removed. Only the one which created it.
4. Can't create the icon based on a resource of the targeted app, except if it's of the current app. You can do it from a bitmap though.

For pre-Android O, you can use ShortcutManagerCompat to create new shortcuts too, without any of those limitations.
