如何在主屏幕上创建快捷方式以计数时间

Question

I have an application consists of a button, that starts counting time whenever the button is pressed, and finishes counting when it is pressed again, and so on.

What I want is a shortcut on home screen (if possible, a floating button; if not, just a shortcut) to do the same action as that button.

Is it possible to define actions for shortcuts? how can I achieve that? minSdkVersion = 16.
Thanks in advance.

Answer 1

Here is the library link which creates a counter floating action bar.

And Here is the tutorial to make that FAB floating like in facebook messenger app.

What it does is it display's a floating action button as the overlay view when the application is in the background.
