Android 13: Unable To Ensure The Availability Of Commands Via getAvailableCommands()

[y20k]

Media3 Version

1.0.0-rc01

Devices that reproduce the issue

• Pixel 4a Emulator API 33

Reproducible in the demo app?

Not tested

Reproduction steps

Setting

• a podcast app that plays a single media item
• you want to offer the user a Seek To Next option even though there is no next media item

Proposed solution in #249

Use a ForwardingPlayer that wraps the actual player, override getAvailableCommands() and add COMMAND_SEEK_TO_NEXT to the available commands. This is how I implemented that.

val forwardingPlayer = object : ForwardingPlayer(player) {
    override fun getAvailableCommands(): Player.Commands {
        return super.getAvailableCommands().buildUpon()
            .add(Player.COMMAND_SEEK_TO_NEXT)
            .build()
    }
}

Expected result

• the MediaSession and the Notification both offer Seek To Next
• a MediaSession.Callback receives in onPlayerCommandRequest the command Player.COMMAND_SEEK_TO_NEXT when a user tapped on Seek To Next

Actual result

Player.COMMAND_SEEK_TO_NEXT in onPlayerCommandRequest received, when user taps on Seek To Next?

On your ForwardingPlayer, can you also override method isCommandAvailable(@Command int command) to return getAvailableCommands().contains(command)?
