Implement the Callbacks

To implement the Auto Update SDK, include the following callback methods:

Method	Description
`onInitializationSuccess`	Triggered when SDK initialization is successful.
`onUpdateStatus`	Triggered when a new version of the app is available, and immediately after invoking the`checkForUpdate()`method.
`onDownloadStarted`	Triggered when permission to install has been granted by the player, and the download process begins. The SDK will attempt to download the new app version.
`onProgress`	Triggered when the download is initiated and when every new byte or packet is downloaded thereafter. You may use it to show download progression in real-time.
`onDownloadEnded`	Triggered when the download process is complete.
`onInstallationReady`	Triggered when the SDK is ready to start the installation process.
`onError`	Triggered when an error occurs during the update process, excluding initialization failures. Follow the instructions in the Auto Update SDK troubleshooting article and try to re-initialize again based on the error.

Example code

Below is the example code for the implementation:

bridgeAPI.init(this, config, object : IUpdateCallback {
    override fun onInitializationSuccess() {
        Log.v(tag, "Initialization successful.")
    }

    override fun onUpdateStatus(status: UpdateStatusModel) {
        Log.v(tag, "Checking whether a new version is available: ${status.isUpdateAvailable}")
    }

    override fun onDownloadStarted() {
        Log.v(tag, "Downloading the new app version.")
    }
    
    override fun onProgress(progress: Int) {
        Log.v(tag, "Progress: $progress")
    }

    override fun onDownloadEnded() {
        Log.v(tag, "The new app version has been downloaded.")
    }

    override fun onInstallationReady() {
        Log.v(tag, "The new app version has been downloaded and is ready to install.")
    }

    override fun onError(errorCode: Int) {
        Log.v(tag, "Error: $errorCode")
    }
})
