YourPhone.AppProxyConnection

Trigger audio workflow on remoting workflow start instead of inside Orchestrator since remoting workflow is the "main" workflow

Manages volume of audio during app remoting Audio Streaming

Returns the last saved volume for from the database.

Set volume slider and mute status for all windows under , send the new volume to the phone, and save to the database.

Send the last saved volume in the database for , to the phone

ConnectionService owns the fundamental connection setup, initializing workflows, and setting up channels

Public facing method that takes in handle requests, does handle management, and requests a connection Only one handle for each workflow can be requested at once. N+1 requests will throw InvalidOperationException

Name of workflow to start token handle to connection for the workflow

This method ensures that only one connection attempt occurs at once All other invocations will wait for the main connection attempt to succeed (or fail) and will adopt that result as well Exception is thrown (and standardized to ConnectionServiceException) if the connection attempt fails or times out

Token by caller for cancellation (e.g. cancel via Close) Task to wait for a connection attempt to complete

Actual logic to form a connection Underyling components throw if the connection attempt fails or times out

Correlation ID to pass around and to Android CancellationToken to cancel the operation Task to wait for a connection attempt to complete

This object adapts the Nano IClient interface to APC's IClientAdapter interface This gets a client which is already connected and maintains it. It also creates a message channel so communication is possible with the device. The message channel is for the invocation of workflows The client is the first recipient of any new channels created. It also monitors the connection (instability/close)

Waits for the client to finish setting up its internal objects Exceptions thrown: - TaskCanceledException - Close is called and current operations will be canceled - OperationCanceledException - Cancellation token passed into WaitForOpenAsync has been canceled

Cancellation token Returns when client has finished setting up internal objects

This object adapts the Nano IConnect interface to APC's IConnectAdapter interface This gets the local handshake request in InitializeAsync and uses the remote handshake response in OpenAsync

Initializes the p2p transport Exceptions thrown: - TaskCanceledException - Close is called and current operations will be canceled - OperationCanceledException - Cancellation token passed into InitializeAsync has been canceled - InvalidOperationException - Invalid call sequence

Returns connection string to be sent to peer for handshake

Using the peer's connection string, attempts to open a connection with the peer Exceptions thrown: - TaskCanceledException - Close is called and current operations will be canceled - OperationCanceledException - Cancellation token passed into InitializeAsync has been canceled - InvalidOperationException - Invalid call sequence - ConnectionServiceException - DirectConnectionTimedOut, Error, Canceled, Failed (unexpected), RemoteTransportTooOld, RemoteTransportTooNew

Peer's connection string Returns client object with open connection

Encapsulates the workflow-level message channel. The lifetime of this object is the lifetime of the workflow

Initializes and opens the workflow message channel Throws OperationCanceledException if canceled Throws InvalidOperationException if Open is called incorrectly

Task completed on Open success

Encapsulates logic to start a workflow

Starts a workflow asynchronously WorkflowException may be fired for unexpected code issues, cancellations, or connection failures

Name of workflow to start Opportunity to register listeners with the workflow message channel before open Cancel token to stop the connection while its still starting WorkflowMessageChannel to represent the workflow connection

Get last volume level that was saved in the database for

Save in the database as the latest volume level

Get last mute state that was saved in the database for

Save in the database as the latest mute state

Used as a Stream by APC, on write of bytes we send them to AP where they are written into the actual Stream

Remoting session describes the time while the user is remoting into the phone This interface represents lifecycle events of the remoting workflow

Called when the remoting session is starting and objects are initialized for the session

Contains objects associated with a new start of the session

Called when the remoting session has started

Called when the remoting session has stopped

Service interface for the lifecycle events of AppProxyConnection

Called when the remoting session is starting and objects are initialized for the session Must be cautious about blocking calls as this is called during initialization of the module

Clear caches on device change

Retrieves the cached value or starts a request to fetch the value. When starting a new request, create a new cache

Cache location tcsLock Returns cached result if successful, otherwise TaskCanceledException is thrown

Shoulder taps then returns cached result Possible exceptions: - TaskCanceledException if shouldertap fails - TimeoutException if shouldertap times out

Cache Returns cached result if successful, otherwise exception is thrown

Shoulder taps for all device state Task completes on success otherwise throws Possible exceptions: - TaskCanceledException if shouldertap fails - TimeoutException if shouldertap times out

Defines the source generated JSON serialization contract metadata for a given type.

The default associated with a default instance.

The source-generated options associated with this context.

Asks Android to check the permission status

type of permission to check cancellation token Returns PermissionStatus based on current permission status

Asks Android to show permission so user can provide input Its possible that the permission does not show on Android because the permission is disabled

type of permission to check cancellation token Returns user input from permission prompt on Android

Asks Android to launch app settings so user can change the permission value Returns when the user changes the value, closes the app settings, the request times out, or a new request has been made

type of permission to check cancellation token Returns user input from permission prompt on Android

Triggers the appropriate audio streaming permission flow based on params provided. Set to null if multiple apps is not supported.

IStateMachineWatcher listens for state changes and ensures that the target state machine does not get stuck in an unexpected state.

Initialize the watcher with a target state machine.

Target state machine Command to be issued if the state machine spends longer than the in an invalid state. Command details to be sent to the state machine if the timeout is reached Maximum time without any transition out of an invalid state. Exceeding the delay causes the watcher to timeout and issue the List of states which are not valid long running states. Exceeding the while in one of theses states will cause a timeout

If json[key] is a valid integer, parse the int and set it to value. Returns false if json[key] is not a valid int. Otherwise returns true.

This helps coordinate the request and response of messages where the request is fire and forget and a response comes another way. The relationship between the two messages is a transaction id. This helps connect the two together so the caller can expose an async method.

This starts a transaction and returns a Task that can be waited on for transaction compmletion.

AsyncTransaction that allows the caller to wait and get the transaction id

This completes the transaction. The task returned when the transaction was started is completed.

Unique id that links to the start of the transaction Value to return in the transaction

Supported is whether phone supports audio Enabled is whether PC has EXP enabled

whether audio code can run

This class is used to ensure that a single method will run just once However, it may run again if the method throws or the object is Reset One example of this class's use if there is a method that creates a connection. If there are multiple calls to create that connection from different sources, then only one thread should actually create the connection, while the other threads wait for that thread's completion before continuing This class is thread safe

Returns the current run task so callers can check status without invoking a run Returns null if there is no current task

Runs the single method if not yet run, or waits for a previous call to complete and returns on completion

Returns a task to wait for completion

Resets the object so that runs are canceled and threads are released

Contains extern methods from "USER32.dll".

Enables the specified process to set the foreground window using the SetForegroundWindow function. The calling process must already be able to set the foreground window. For more information, see Remarks later in this topic.

Type: DWORD The identifier of the process that will be enabled to set the foreground window. If this parameter is ASFW_ANY, all processes will be enabled to set the foreground window. Read more on docs.microsoft.com. Type: BOOL If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. The function will fail if the calling process cannot set the foreground window. To get extended error information, call GetLastError. The system restricts which processes can set the foreground window. Normally, a process can set the foreground window by calling the [**SetForegroundWindow**](nf-winuser-setforegroundwindow.md) function only if: - All of the following conditions are true: - The calling process belongs to a desktop application, not a UWP app or a Windows Store app designed for Windows 8 or 8.1. - The foreground process has not disabled calls to **SetForegroundWindow** by a previous call to the [**LockSetForegroundWindow**](nf-winuser-locksetforegroundwindow.md) function. - The foreground lock time-out has expired (see [**SPI_GETFOREGROUNDLOCKTIMEOUT** in **SystemParametersInfo**](nf-winuser-systemparametersinfoa.md#SPI_GETFOREGROUNDLOCKTIMEOUT)). - No menus are active. - Additionally, at least one of the following conditions is true: - The calling process is the foreground process. - The calling process was started by the foreground process. - There is currently no foreground window, and thus no foreground process. - The calling process received the last input event. - Either the foreground process or the calling process is being debugged. A process that can set the foreground window can enable another process to set the foreground window by calling **AllowSetForegroundWindow**. The process specified by the *dwProcessId* parameter loses the ability to set the foreground window the next time that either the user generates input, unless the input is directed at that process, or the next time a process calls **AllowSetForegroundWindow**, unless the same process is specified as in the previous call to **AllowSetForegroundWindow**.
