This method being called does not indicate that playback has failed, or that it will fail. The player may be able to recover from the error. Hence applications should *not* implement this method to display a user visible error or initiate an application level retry. `https://developer.android.com/reference/androidx/media3/common/Player.Listener#onPlayerError(androidx.media3.common.PlaybackException)` is the appropriate place to implement such behavior. This method is called to provide the application with an opportunity to log the error if it wishes to do so.
| Parameters |
|---|---|
| `https://developer.android.com/reference/androidx/media3/exoplayer/analytics/AnalyticsListener.EventTime eventTime` | The event time. |
| `https://developer.android.com/reference/java/lang/Exception.html error` | The error. |

Called when seeks have been dropped while in `https://developer.android.com/reference/androidx/media3/exoplayer/ExoPlayer#setScrubbingModeEnabled(boolean)`.
Seeks are dropped in scrubbing mode when at least two calls are made to `https://developer.android.com/reference/androidx/media3/common/Player#seekTo(long)` while an earlier call to `https://developer.android.com/reference/androidx/media3/common/Player#seekTo(long)` is still being processed (i.e. the resulting frame hasn't been rendered/released yet). The most recent seek is queued to process later and any intermediate seeks are dropped.
| Parameters |
|---|---|
| `https://developer.android.com/reference/androidx/media3/exoplayer/analytics/AnalyticsListener.EventTime eventTime` | The event time. |
| `int droppedSeeks` | The number of dropped seeks since the last call to this method. |
