class EspressoRemote : RemoteInteraction
A singleton class that facilitates communication between other Espresso instance that may be running in different processes.
This class depends on InstrumentationConnection to notify about the discovery of other remote Espresso instances and provide their Messenger object to use for further IPC.
To get the instance of this object getInstance should be called. The user of this class should then call init prior to attempting to use any functionality of this class. Call terminate after using EspressoRemote to release any resources. Failure to do so will lead to memory leaks and unexpected behavior.

rootMatcher: Matcher<Root!>!,
viewMatcher: Matcher<View!>!,
iBinders: (Mutable)Map<String!, IBinder!>!,
viewAssertion: ViewAssertion!
): Callable<Void!>!
Creates a callable to run Espresso check interaction on remote processes
The caller is expected to schedule the task to run.
synchronized fun createRemotePerformCallable(
rootMatcher: Matcher<Root!>!,
viewMatcher: Matcher<View!>!,
iBinders: (Mutable)Map<String!, IBinder!>!,
viewActions: Array<ViewAction!>!
): Callable<Void!>!
Creates a callable to run a perform interaction on remote processes.
If there no remote Espresso currently running in a timely manner the interaction will not be executed and a NoRemoteEspressoInstanceException will be thrown.
java-static fun getInstance(): EspressoRemote!
Returns an instance of EspressoRemote object.
synchronized fun init(): Unit
Must be called prior to using any functionality of this class.
During initialization the instance of this class will be registered with .
synchronized fun terminate(): Unit
Must be called to disable further use of this class.
During termination the instance of this class will be un-registered with and clear the list of known remote Espresso Messengers.
volatile java-static val isRemoteProcess: Boolean
Represents whether the current instance is running in a remote process or not
