Starts a task that calls the floating-point sample-array write. |
| WriteAsync(Byte[], Int32, Int32) |
Starts a task that calls the blocking byte-array write. |
| WriteAsync(ByteBuffer, Int32, WriteMode) |
Starts a task that calls the byte-buffer write. |
| WriteAsync(Int16[], Int32, Int32) |

WriteAsync(Int16[], Int32, Int32, WriteMode)
Starts a task that calls the 16-bit sample-array write with the supplied write mode.
public System.Threading.Tasks.Task<int> WriteAsync(short[] audioData, int offsetInShorts, int sizeInShorts, Android.Media.WriteMode writeMode);member this.WriteAsync : int16[] * int * int * Android.Media.WriteMode -> System.Threading.Tasks.Task<int>Parameters
- audioData
- Int16[]
The source array of 16-bit audio samples.
- offsetInShorts
- Int32
The starting source index, in 16-bit array elements.
- sizeInShorts
- Int32
The maximum number of 16-bit array elements to write.
- writeMode
- WriteMode
The synchronous write's blocking mode; it does not control task scheduling.
Returns
A task with the accepted 16-bit element count, possibly zero, or a negative write error code. Acceptance does not mean playback has completed.
