Flag for use with PendingIntent.GetActivity(Android.Content.Context, System.Int32, System.Int32, System.Int32), PendingIntent.GetBroadcast(Android.Content.Context, System.Int32, System.Int32, System.Int32), and PendingIntent.GetService(Android.Content.Context, System.Int32, System.Int32, System.Int32): if the described PendingIntent already exists, the current one is canceled before generating a new one. You can use this to retrieve a new PendingIntent when you are only changing the extra data in the Intent; by canceling the previous pending intent, this ensures that only entities given the new data will be able to launch it. If this assurance is not an issue, consider PendingIntentFlags.UpdateCurrent.
