Press-app

An Android app developed in Kotlin, using Retrofit, Coroutines,ViewModel, LiveData, Materials and NewsApi.

Pick a country

Here we look at the first screen after the splash, where we pick the country we want the news from. the id of the country as well as its language is being transfered on click to the viewmodel. There are two recyclers view and one searchView. The left recycler view holds pictures of flags representing countries used for their news and languages. The main one holds CircleViews of flags pictures, from which we can scroll to the right to pick a country. The searchView is updating the viewmodel after each character inserted. Leading it to scroll the main recycler to display our desired country. By selecting a flag from the side recycler we order to display as well from the main recycler the wanted country.

Headline Fragment

Here is the headline fragment. The previous screen sent data about the country we want to display news from. We launched a liveScope of the Coroutines, LiveData implementation from where we call the retrofit builder inside the viewmodel using the appropriate suspended function, because we don't want our app to lag and get callbacks, updateing our recycler and it's adapter.

Category in headlines fragment

Same as previously in a different language.

International fragment

Every user can reach international news, and ask for an accurate research using the searchView. Every time a researched is launched, the recycler is cleaned and reinitialized in a background thread.
