Hi Justin, I want the app widget to be displayed when I click on the button at the bottom of the screen There will be an empty screen above the button.
I have implemented the following logic: When the button is clicked, a message is broadcasted. On receiving the broadcast, I am trying to display the app widget onto the empty screen. Is it possible to display the app widget in the "onReceive" function?.... Regards, Anand.
