This project created base on VOI Technology assignment for hiring process.
It is base on Kotlin and Spotify webService with most the new Android architecture components and another useful library on android such as
- viewModel
- liveData
- Retrofit
- Dagger 2
- data Binding
- MVVM
- Room
- Kotlin Coroutines
- Glide
- androidTest with espresso and mock
-
SplashActivity is the launcher activity.It's just contains of Kotlin Coroutines for start another activity.
-
MainActivity : It's contains paging list RecyclerView which just show vertical list of
- MainActivityViewModel viewModel of MainActivity, handle Data Request and action. Request to DataSource.Factory is based on changing query.
- MainDataSourceFactory DataSource Factory for Handle PageKeyedDataSource data request.
- PageKeyedDataSource handle request by paging parameters offset and pageSize. I've implemented Room but It's not connected to this part.
- BoundaryCallback is not implemented because we just fetch data from network but if we're going to add Room in the process that would be necessarily too.
-
ListWithoutPaging : It' contains vertical RecyclerView and in the RecyclerView I've implemented horizontal RecyclerView and that's contains Artist, Album, Playlist and Track.
- ListWithoutPagingViewModel : viewModel of ListWithoutPaging, handle Data Request and action. Request to DataSource.Factory is based on changing query.
- DataRepository implemented for Handle request data.
-
BaseApp is Application class and the link between Kotlin with JNI. I've two String parameters in JNI for clientId and ClientSecret.
-
RestRequest is main Interface of Retrofit and It can handle development and test mode. in this part we have 2 webService getAccessToken for request token Oath2 form server and searchArtist for get list data. All the class related to Retrofit is in api package.
-
BindingAdapter class used for custom attribute we need for dataBinding.
-
SpotifyDb is Room database for save Artist list data, ArtistDao is contains query should be run on database. and for saving Image object in database I used DataConvertor class to change the format from object to Json and Json to images.
-
BaseActivity is a general class and all activities extends from it. Dagger is in this class and it also had some useful module.
