Why widget does not work after reboot?

Question

I have this simple widget and when I click on it, it should open my activity, it works, but it doesn\'t work after reboot. I must delete and then again add widget to my home

Answer 1

The AppWidgetProvider which widgets inherit calls onUpdate on startup when it receives ACTION_APPWIDGET_UPDATE from the operating system.

If you override onReceive without calling super.onReceive(), you would need to intercept this Intent on your own.
