Suppose that The functional requirements of an android battery
checker application are
1) The app should show the current accurate level of the battery
charge.
2) The app should able to monitor/ Understand whether the
battery is plugged in to charger or not (ie: means charging
happening or not)
3) Application should need to trigger warning alarms and
messages when battery level is very low.
4) Application should able to show warning signs when battery is
overcharged (beyond 100% charging)
5) The battery level indicator (percentage / bar etc.) should
need to show exact value.
6) The application should able to monitor the abnormal charging
loss and to report it.
draw an activity diagram of our android battery checker
application: initial state final state decision node ,merge node ,
swimlane guard,...........,
An activity diagram shows a process as a set of
activities, and describes how they must be
coordinated.
ellipses represent actions;
diamonds represent decisions;
bars represent the start (split) or end (join) of
concurrent activities;
a black circle represents the start (initial node) of
the workflow; an encircled black circle represents the end (final
node).
Arrows run from the start towards the end and represent
the order in which activities happen.
