A Simple Android Contact List that simulates interaction with an API.
Clone this repository. Open Andrdroid Studio 2.3.1+, import as existing android project and deploy to your device/simulator.
Via command line ./gradlew assembleDebug and then adb push <your_device>
Android tools 25 is a requirement for this project.
1. Displays sample data coming from a local JSON File
2. Uses Android's Recycler View.
a. Display views that show the person's picture (on the left), name (as the title), and position (as the subtitle). This is done using an ArrayAdapter.
b. Load the images asynchronously so UI is not blocked while waiting for downloads.
c. When a row is clicked, it takes you to a detail view that display the contact details (picture, name, and position, similarly to the OS contacts app) a fade in transition to that view is added.
- minSdk is 19 and target is 25 to cover 80% of the current market.
- Glide is used to fetch images from the network but it is abstracted in the
NetworkImageclass to prevent logic to rely on a specific library. - Repositories are modeled after data that comes from a local JSON file which is parsed using Google's GSON library. Again this implementation detail is abstracted from that layer so that changing this to grab a longer list from an API endpoint would be little to no effort.
This project provides both Instrumentation and Unit tests to showcase both in the context of Android Development.
