Use Interface Callbacks to reduce Coupling between Activity and Fragments and reduce the lines of code

[abhishekbisht1429]

Actual Behaviour
PsLabSensor directly calls methods from fragments such as LuxMeterDataFragment, SoundMeterFragment etc, which increases coupling and also increases lines of codes in the onOptionItemSelected() method of PsLabSensor. In addition it increases chances of introducing bugs when new sensors are implemented.

Expected Behaviour
Interface callbacks can be used to reduce the coupling between PsLabSensor and other data fragments. We can define a interface with common set of methods such as play(), stop(), pause(), resume() etc and have the fragments implement this interface.
