| 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, including initialization failures. Follow the instructions in the Unity Auto Update SDK troubleshooting article and try to re-initialize again based on the error. |
