Players
This guide shows how to use and customize JOIN Stories players in your Android application.
Player View
You can customize the player that opens when the trigger is clicked.
val playerConfiguration: PlayerConfiguration = PlayerConfiguration()
cardTrigger.playerConfiguration = playerConfiguration
bubbleTrigger.playerConfiguration = playerConfiguration
Player view type
You can force the player to use horizontal mode for stories or vertical mode for short videos if you don't want to rely on the JOIN Studio settings.
val configuration = PlayerConfiguration(playerType = PlayerType.STORY)
//or
val configuration = PlayerConfiguration(playerType = PlayerType.VERTICAL)
Player Start Opening Animation (only standalone mode)
The start opening animation can be changed when the player is used in standalone mode. By default, the animation start from the bottom of the screen.
// enum class PlayerStandaloneAnimationOrigin {
// TOP_LEFT, BOTTOM_LEFT, BOTTOM, BOTTOM_RIGHT, TOP, TOP_RIGHT
// }
JOINStories.startPlayer(
...
configuration = PlayerConfiguration(playerStandaloneAnimationOrigin: PlayerStandaloneAnimationOrigin)
)
Player Vertical Anchor
The attribute changes the player anchor when the player's height is smaller than screen height. The default anchor is TOP
// enum class PlayerVerticalAnchor {
// TOP, BOTTOM, CENTER
// }
trigger.playerConfiguration = PlayerConfiguration(playerVerticalAnchor: PlayerVerticalAnchor)
Player Background Color
The attribute changes the background color of player. The background color is Color.BLACK by default
trigger.playerConfiguration = PlayerConfiguration(playerBackgroundColor: Int)
Player Horizontal Margins
The attribute changes the player's left and right margins. By default, the player has no margin.
trigger.playerConfiguration = PlayerConfiguration(playerBackgroundColor: Int)
Player Corner Radius
The attribute changes the corner radius of player. By default, the corner radius is 0.
trigger.playerConfiguration = PlayerConfiguration(playerCornerRadius: Int)
Player Progress Bar
These attributes change the style of the progress bar at the top of the player
trigger.playerConfiguration = PlayerConfiguration(playerProgressBarDefaultColor: Int)
trigger.playerConfiguration = PlayerConfiguration(playerProgressBarFillColor: Int)
trigger.playerConfiguration = PlayerConfiguration(playerProgressBarThickness: Int)
trigger.playerConfiguration = PlayerConfiguration(playerProgressBarRadius: Int)
Tip
Default Color : The default color is
WHITEwith 50% of alphaFill Color : The default color is
WHITEThickness : By default, the thickness is
2dpRadius : By default, the radius is
6dp
Vertical Player configuration
Feature available from SDK v3.9.0+
The Vertical Player is a new full-screen playback mode, as an alternative to the classic "story" player (horizontal navigation, chapters). It follows the conventions of vertical video feeds seen on social networks: vertical swipe navigation between stories, a vertical progress bar, and adapted controls.
Video sizing
videoSizing simply controls how the video fills the player's screen:
VerticalPlayerVideoSizing.FIT : (default value): respect the 16:9 video format and keeps its original aspect ratio, with black bars if needed (letterboxed).
VerticalPlayerVideoSizing.FILL: the video fills the entire screen edge-to-edge, cropping the image slightly if needed.
Player Standalone
JOINStories.showVerticalPlayer(
context = this,
alias = "<your_join_alias>",
videoSizing = VerticalPlayerVideoSizing.FILL
)
JOINStories.showVerticalPlayer(
context = context,
alias = "<your_join_alias>",
videoSizing = VerticalPlayerVideoSizing.FILL
)
Player Embedded
You can't change video sizing on player embedded for now.
Action buttons
What is it?
The Vertical Player exposes a space where your app can add its own action button (for example, an "Add to my list", "Like" or "Share", button). Just provides your View or Button. JOIN just gives it a place to live and tells it which story is currently on screen.
How it works?
- You provide an array of view. All button's UI customization and logic is in your hands.
- SDK renders it in a fixed spot on the right side of the Vertical Player.
- SDK passes the current story to your component whenever the user swipes to a new one.
- Everything else, state, styling, click handling, network calls : is entirely up to you.
- SDK does not store or manage the button's state. If a user taps it, that's your app's logic to handle.
- Your component gets the current story object as input, with public fields only (id, title, cover, etc.). No private or internal data is passed.
// Example for single action button (e.g. Screen 1)
JOINStories.showVerticalPlayer(
context = this,
alias = "<your_join_alias>",
configuration = PlayerConfiguration(
customActionButtons = { storyData ->
if (storyData.isEmpty) emptyList()
else listOf(MyAddToListButton(this))
}
)
)
// Example for few action buttons (e.g. Screen 2)
JOINStories.showVerticalPlayer(
context = this,
alias = "<your_join_alias>",
configuration = PlayerConfiguration(
customActionButtons = { storyData ->
if (storyData.isEmpty) emptyList()
else listOf(MyAddToListButton(this), MyLikeButton(this))
}
)
)
// Example for single action button (e.g. Screen 1)
JOINStories.showVerticalPlayer(
context = context,
alias = "<your_join_alias>",
configuration = PlayerConfiguration(
customActionButtons = { storyData ->
if (storyData.isEmpty) emptyList()
else listOf(MyAddToListButton(context))
}
)
)
// Example for few action buttons (e.g. Screen 2)
JOINStories.showVerticalPlayer(
context = context,
alias = "<your_join_alias>",
configuration = PlayerConfiguration(
customActionButtons = { storyData ->
if (storyData.isEmpty) emptyList()
else listOf(MyAddToListButton(context), MyLikeButton(context))
}
)
)

Screen 2
Tips for placement
Action buttons are added from bottom to top of the space available and have a max height and width of 40.
