Version: ToT Android Client
OS: Android 6

What steps will reproduce the problem?
(1) Click on a host in the list
(2) Wait until the desktop shows up.

What is the expected output?

Nobody holds reference to the Chromoting activity (for showing host list) and the activity should be deleted by the GC.

What do you see instead?

SessionConnector holds reference to the activity as ConnectionListener and the JNI client holds a reference to SessionConnector also as ConnectionListener... The activity may be in invalid state since it is kept alive out of its lifecycle.
