Hang Up Block

A simple utility to block the edges of the In-Call UI Hang-up button, making it less likely you'll accidentally hang up an ongoing phone call when you pick up your phone.

*** THE UI IS DESIGNED TO WORK WITH THE DEFAULT PHONE APP ON THE MOTO X RUNNING KITKAT ***

It is unlikely the overlay screen will land in just the right spot for any other phone app on any other phone.
----------------------------------------------------------------------------------
Simply launch the app to enable or disable its only feature via a simple setup screen.
When enabled the app will:
- Detect if the Phone app is running
- Detect if a call is active
- If both of the above are true, it will draw an overlay screen on top of the Hangup button
- If you hang up or leave the Phone app (tap Home, etc) the overlay will be removed
- With the optional PERSIST setting: If you return to the Phone app while still on a call, the overlay will be drawn again

The overlay screen is transparent in the middle and black on the left and right edges. If you tap the transparent section (which shows the original Hangup button through it) the app will hang up your call.

NOTE: It seems that both the "call in progress" and the "Phone" screens are part of the same app, and I draw my overlay whenever the app is open (and you're on a call). If you enable the PERSIST feature, the overlay will end up being drawn on the Phone app even if you are scrolling through contacts, etc (again, only while you are in a call). If this bothers you, you can disable PERSIST and the overlay will not be redrawn till the NEXT call. [I've disabled PERSIST by default]

Permissions:
Directly call phone numbers: used only to hang up an ongoing call
Disable your screen lock: an unavoidable side effect of using Tasker to make this (not used)
Retrieve running apps: to determine when Phone is running
Prevent phone from sleeping: an unavoidable side effect of using Tasker to make this (not used)
