Draw over another app?

I am wanting to be able to start an activity of my app from anywhere in Android. I am wanting to do this by overlaying a button over any apps that are open.

How would I go about doing this, if it is possible.

Surely you can do this. There's "Stand-Out" library available in GitHub. You can check it here - https://github.com/pingpongboss/StandOut

And this works super fine without root permission.

You can do it, without root or any modifications to the system, as Facebook clearly show with Chat Heads.

All you need is a special permission android.permission.SYSTEM_ALERT_WINDOW that lets you add windows with type TYPE_SYSTEM_ALERT that are displayed above other apps. Then, with some intimate knowledge of WindowManager, you can do practically anything you want.

It would be pretty difficult to do this for a specific app but probably not impossible.
