Binding Few Activities To One Service - Class Which Connected Treated Like Service - Can't Destroy Activity

I will start from my approach I want to have one service which is running even if none of application screen is visible for user. This service will scan for beacons. Every screen

Solution 1:

In my ServiceConnector class should be:

context.unbindService(mConnection);

instead of this line:

scanningService.unbindService(mConnection);

I don't know how this misscoding come from, but I lost few hours, so be sure that you unbind from context of activity.

Normally i would delete this question, but one person make it favorite so I want to show what was the reason of my error.
