- 3 screens (fragments):
- list of audio files and recordings (RecyclerView)
- audio recorder

Repo includes only the android side. Backend is on AWS, and external URL's (responsible for the results) are not in the repo.
In android, Fragments are components of the UI, and ViewModels hold the business logic and state. Fragments are used in Activities (windows/screens), in this case, the app uses a single Activity and 3 Fragments:
-
FilesListFragment - displays a list of files using a RecyclerView (reuses elements when scrolling), and allows users to switch between different file providers (music files and recordings). The fragment utilizes the FilesListViewModel to manage data and interactions, and navigates to a file info screen when a file in the list is clicked.
-
RecorderFragment - audio recorder. Includes buttons to start and stop recording, and a chronometer to display the recording duration. Uses the RecorderViewModel to manage the recording process.
-
FileInfoFragment - displays information about a selected file. Includes functionality for playing audio files, and displaying results from the text and image APIs (using other ViewModels). LiveData is utilized to communicate the status of audio-to-text operations and other operations. (In android, LiveData allows UI components to observe changes in the data, and it is used throughout the app.)
UI: the default theme is used for the app (no styling preferences).
The app was tested on Android v10.
