Apps have no control on adding/removing widgets on the home screen.
The reason is simple. If any app can add a widget on the home screen programmatically, the home screen can easily be a mess.
So, the user should add the widget by himself, and it is simple.
1. Open App Drawer2. Go to Widget list, select the widget and hold it on until the home screen appears3. Place the widget on the home screen
Alternative way to add a widget on home screen.
1. There are several ways to add a widget and it could be slightly different by which Home screen launcher you are using. Tap on a blank space on the home screen and hold your finger there (long press) until the menu appears. Also, there could be a ‘+’ button or press the ‘Menu’ button and select ‘Add’ menu.
2. Go to the ‘Widgets’ menu and find the widget you want to add from the list. You can layout it on the home screen.
