Android Question Two Activities with shake

[AlpVir]

The attached project is a variant of "Two Activities Example".
The second task is started shaking the smartphone; not by pressing a button !!!

It works perfectly, BUT :
- if you press the power button
- if you fall on the screen timeout
no longer able to resurrect the service.
Probably it is a problem that can be overcome with the PartialLock and/or KeepAlive instructions but do not know where to place them.
Someone can help me to complete this (strange) project?
Thank you in advance.

You shouldn't release the partial lock when the activity is paused if you want it to keep running.

You should also make the service a foreground service (Service.StartForeground).
