Vimystry is an simple app displaying videos in a story
There's a main screen with a full screen player. It immediately starts playing videos. Once ready playback loops through all the medias indefinitely. Videos are ordered by creation order.
The UI displays current playing video’s information :
“likes” with short number formatting such as 1k/1m
“author” avatar
User can interact in the following ways:
Tap Right side of the screen to play next video
Tap Left side of the screen to play previous video
Long press anywhere and the video pauses
If the video is in a “paused state”, likes and author information disappear and only reappear once the media is resumed
There are a “Loading” state during data load and an “Error” state if a failure occur
If you want to simulate an error in fetching data uncomment and show error screen, then uncomment this in PostsGraphQLApi :
// throw NoBackendDataException()
Any update from the remote dataset result in the player being reloaded with new content (current refresh is 5 min defined in PostsGraphQLApi)
