Session video -> here!
This project is focused on supporting the second meeting of the Android Study Group by GDG Vigo
The concepts discussed in this session are similar to those covered by the lesson two Udacity Course: Developing Android Apps
In this project the concepts to learn are how to add permissions to your app, AsyncTask, learn about the network input & oputput, difference the main UI thread and the background threads, common libraries to make the job easier.
The application stored in this repository shows different ways to make a request to a server and consume the data coming back in a JSON format.
Specifically, the request is made to a public API that shows different memes and emotions provided by All The Rage Faces site.
The Git repository is divided into different tags to make it easier to explain the different concepts. You can move easily through the repository with the command git checkout {tag}.
Clean project
git checkout start
Clean project generated by Android Studio creating an empty project.
HTTP Request
git checkout http_request
A request is made to the API endpoint with an HttpUrlConnection object and the response is printed on the console in a JSON format.
Parsing the response
git checkout parsing_json
The JSON response is now parsed into a list of entities
Showing the result into a ListView
git checkout meme_listview
Show the meme titles in a ListView with a simple ArrayAdapter with a layout provided by the Android Framework
Custom adapter
git checkout custom_adapter
Changed simple ArrayAdapter by a custom adapter with a layout containing an ImageView, a TexView for the title and a TextView with the meme emotion
Downloading meme images with Picasso
git checkout picasso
Added the Picasso library to download the meme images from the meme list into the ListView adapter.
Using GSON to parse the response JSON
git checkout gson
Added & implemented the Gson library to parse the json response in an easier way
Added Ion libary
Added & implemented the Ion library to ask the meme api in an easier way, also replacing the Picasso libary
