Using Your Own Player (Android)

HotMicMediaPlayer allows you to integrate your own player into your application. In order do to this, you must:
Include the player in your application to be played. (e.g. Bitmovin, JWPlayer, Exo).
Use our protocol to forward commands to your player when the HotMic protocol dictates (e.g. pause the player).
Send to HotMic various player events (e.g. notify HotMic the player is paused).
For using a custom player, the implementation should do the following:
Extend their custom player to support the BaseHMPlayer implementation.
Implement the PlayerCallback getPlayer() function
BaseHMPlayer Interface
This code shows the different values and functions in the BaseHMPlayer interface. If you have any questions about this, please contact our team.

Player Callback Interface
This function is how you define whether you want to use a custom, third party player, or the default one. Implement the getPlayer function in the callback to return a custom player. Returning null will result in the SDK using the inbuilt exo player implementation.
Kotlin
/**
 * Optional
 * If your implementation wants to use a custom player, then ooverride
* this method to construct and return the player * @param context
* @param tag String to identify the player. The implementation has to return this string in
* the BaseHMPlayer.tag variable
* @param listener Callbacks that the player implementation should call on
media state change
* or error
* @return custom implementation which implements BaseHMPlayer. if null,
then default exoplayer
 * will be used
 */
fun getPlayer(
context: Context,
tag: String,
listener: HMPlayerEventListener
): BaseHMPlayer? { return null }
/**

* this method to construct and return the player * @param context
* @param tag String to identify the player. The implementation has to return this string in
* the BaseHMPlayer.tag variable
* @param listener Callbacks that the player implementation should call on

 */
fun getPlayer(
context: Context,
tag: String,
listener: HMPlayerEventListener
): BaseHMPlayer? { return null }
