Demo Videos for Usage of the Android Permission ACCESS_BACKGROUND_LOCATION

• Background Location
  There are two videos of 1 minute each, to demonstrate the difference between without/with background location.
  1. video without background location
  2. video with background location

• There is also a sequence of screenshots, illustrating the procedure in more detail.
• The line of action is the following:
  After the user has agreed to the privacy policy, he will be asked to grant permission for location access. There are two options:
  1. "Allow only while using the map" (without background access to location)
  2. "Allow all the time" (with background access to location)
• During a walk, the recording is started and the menu "Map" is chosen manually.
• After some seconds, the display is switched OFF (to demonstrate the effect) for a short period.
• When the display is switched back ON, we can see different behaviours in the two cases:
1. There is a gap in the recorded Track (undesired).
2. There is no gap in the recorded track, which is the desired behaviour.
• The permission ACCESS_BACKGROUND_LOCATION will enable the user to save battery charge by switching the display OFF, while he is using the app as GPS tracker - continuously recording the device location.
