The technical aspects
The homepage of the app has used android grid view with four different icons for each sub section. The first icon, Lessons and Exercises opens up to an activity created using android fragments. The three fragmented activity has the options of selecting difficulty level. And also the ability to select the Lessons or Exercises. Android listview format is used to showcase the lessons each with an image. The data and images of the lessons are stored in an SQLlite database and loaded on the single activity. The questions are also stored in an SQLlite database with three different tables for each difficulty level. And the index number of the correct answer to each question is stored in a separate column and it is checked with the user's response in evaluation. The high-score is sent back to the start page after each exercise and updated.
The news is generated by a free API from newsapi.org and taken using a JSON format. Then the JSON is broken down and each detail is assigned to the particular field. Since the api can not be categorized based on the language the it was sorted out by the country(i.e Germany).
The picture dictionary is created using an image slider. The pictures are stored in a blog and loaded in real time. And in the listening section short audio clips are stored in a builtin database and loaded.
