## VAST event compatibility
**Fully supported**
All video players must fire the callbacks that trigger the following
events:
`complete`, `creativeView`,
`firstQuartile`, `impression`, `midpoint`,
`pause`, `resume`, `rewind`,
`start`, `thirdQuartile`
**Optionally supported**
Because Android applications do not typically control the device's volume,
the `mute` and `unmute` events are generally not
fired.
Be sure to disable seeking in your video player while ads are being played. If the SDK detects seeking during an ad, it throws an error.
