How to show widget the same as Alarm (Clock APP) widget?

Question

I need to make this application the same as the Clock Alarm function. As soon as we installed Alarm for some time, for example, 3.15PM (even the application does not work). He shows in

• Today's notification screen is

  we can do this (your alarm ......) using the APP extension (using the user default settings), right?

  2. Like a popup screen

  3. Emergency tooltip on lock screen -

My question is

a. How can we achieve both 2 and 3, Is this the same APP extension concept?

b. At first, I suppose they used custom defaults. Can we make access to the API in the APP extension, for example periodically check the web service?

Please offer a solution / idea to achieve this.

Thanks!

Answer 1

No, this is not the same as an application extension or widget. I also do not believe that it is possible to do what you are trying to do.
