Programmatically add widget to home screen in Android

Question

I developed an application for the Android widget and its work is excellent. Now my client asks that when the user installed this application, it should automatically be placed on the top desktop. How to do it? please help me.

Answer 1

Starting with Android O, in your application you can create a request for the system to bind the widget to a supported launcher.

• Create a widget in the application manifest file
• Call requestPinAddWidget () method
