Step 1. Connect the Chromecast device to your TV and open the Haystack TV app on your Android or iOS device.
Step 2. Once you've opened the app, you'll see a Chromecast icon on your app. It should be located on the top bar on your Android device and in the bottom left corner of the video player on your iOS device. Select that icon.
Step 3. After selecting the Chromecast icon, you'll see a list of connected Chromecast devices near you. Select your device from the list. You should now be able to cast all videos from your Android device to your TV. If you want to disconnect the device, just click on the same icon and select 'disconnect'.
