PayoneerTestApp

A Native Android (JAVA) App DEMO challenge for Payoneer.

A brief preview

Getting Started

This app was designed using the MVVM architecture. I also adapted the UI convention of
one Activity (MainActivity), multiple fragments using the Android Navigation Component.

I used retrofit for networking, Gson for object mapping while using OkhttpClient for cache
control. I wrote a custom Retrofit Callback class to enable me handle errors such as
SocketTimeoutException, UnknownHostException, ConnectException, JSONException,
IOException and other standard network errors properly.

For better user experience, a third party loader libary
('com.elyeproj.libraries:loaderviewlibrary:2.0.0') was used to serve as a placeholder while making network calls.

Details of the project structure explained below

• /app
  #This is where all the application's directories are contained.

  • /adapters
    #This directory contains the adapter for binding data to the recycler view.

  • /dao
    # this directory contains the ApiInterface for retrofit.

  • /models
    # This directory contains all the POJO classes.

  • /repositories
    # This directory contains the repositories which abstracts data from the ApiInterface
    and feeds to respective view models.

  • /ui
    # This directory contains all UI modules like each module contained within is a subdirectory
    containing a fragment and its view model.

  • /utils
    This directory contains helper classes like the Retrofit service class and the Retrofit
    callback class.

• MainActivity.java
  # Main activity class file.

• PayoneerTestApp.java
  # Main application file which extends the Application class.

• SplashActivity.java
  # Splash Screen activity for earlier android Os versions.
  NB: Recent android versions use the app theme and the roundIcon as a default splash screen.
