in

Attributes

Remarks

Attach the given bidirectional communication streams to be used for transporting system data between associated devices.

The companion service providing these streams is responsible for ensuring that all data is transported accurately and in-order between the two devices, including any fragmentation and re-assembly when carried over a size-limited transport.

As an example, it's valid to provide streams obtained from a BluetoothSocket to this method, since BluetoothSocket meets the API contract described above.

This method passes through to CompanionDeviceManager#attachSystemDataTransport(int, InputStream, OutputStream) for your convenience if you get callbacks in this class.
