Call
Constructs a new instance of a CallClient. This call does not join a room, rather a join must be done explicitly via CallClient.join.
Parameters
app
The application context
lifecycle
Optional: if provided, the CallClient will automatically be cleaned up when the owner of the Lifecycle is destroyed.
handler
Optional: the handler for the thread on which you wish to interact with the CallClient. Callbacks will be given on this thread, and CallClient APIs should also be invoked from this thread. If this is omitted, then the main application thread will be used.
