This is an "objective tracking" application.
You can set objectives inside the app, with a starting and an ending date (eg: Read 60 pages from today to 10 days from now). The app tells you, for example, how many pages per day you should read in order to achieve your goal in that set time, and updates the daily count based on whether you completed your daily objective the day before.
The UI Layer consists of three activities:
Apart from MainActivity.java (which displays active objectives), the other ones
are pretty self explanatory.
There is also an adapter used in MainActivity.java by a RecyclerView.
These activities communicate with the data layer through the use of a ViewModel (ObjectiveViewModel.java).
The Data Layer code can be found inside the Objectives folder.
There is a basic class, named Objective.java, which represents the objectives set by the user.
Using this as a base, I implemented a ViewModel, a Database (using Android Room), and other helper classes used by these basic functions (Enum for Objectives, Type Converters, Data Acess Object, etc.)
In order for the app to be able to send daily notifications, and to reset the 'daily completion' state of the objectives,
an alarm needs to be set using AlarmManger.
This Alarm, in turn, needs to be received by a BroadcastReceiver, which in this case is AlarmReceiver.java.
First, this class identifies the type of alarm that has fired off, and then sends the appropiate message to MainActivity.java,
which is where the implementations of the responses can be found.
Instrumentation tests can be found inside the androidTest folder.
I didn't write any unit tests because, honestly, I didn't feel like it.
The app is translated in both English and Spanish, and resource files can be found inside
the res folder.
This is not meant to be a real and fully working app, it's just a side project I did in order to get the hang of learning a new framework.
