Instructs the receiver to discard all pending MIDI data.
| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | [getMaxMessageSize](https://developer.android.com/reference/kotlin/android/media/midi/MidiReceiver#getMaxMessageSize())`()`
Returns the maximum size of a message this receiver can receive.

Called to send MIDI data to the receiver without a timestamp. Data will be processed by receiver in the order sent. Data will get split into multiple calls to[onSend](https://developer.android.com/reference/kotlin/android/media/midi/MidiReceiver#onSend(kotlin.ByteArray,%20kotlin.Int,%20kotlin.Int,%20kotlin.Long))if count exceeds[getMaxMessageSize](https://developer.android.com/reference/kotlin/android/media/midi/MidiReceiver#getMaxMessageSize()). Blocks until all the data is sent or an exception occurs. In the latter case, the amount of data sent prior to the exception is not provided to caller. The communication should be considered corrupt. The sender should reestablish communication, reset all controllers and send all notes off.

Called to send MIDI data to the receiver with a specified timestamp. Data will be processed by receiver in order first by timestamp, then in the order sent.
