Applixir SDK integration with an Android application requires a WebView component to be created in the Android application Activity. This WebView displays a HTML page (or a video player as per your implementation) in which the integration code is implemented. Refer HTML Integration for detailed instructions.
On a certain action in the webpage like page load, click of a button, timer etc., invokeApplixirVideoUnit method should be invoked to play the reward video ad. When the method is invoked, Applixir player loads and initiates the ad. Use the status callbacks to initiate appropriate actions to be taken once the video ad completes. The Applixir video player closes automatically.
