Events for observing session lifecycle.
A typical session lifecycle looks like this:
- An installer creates a session to indicate pending app delivery. All install details are available at this point.
- The installer opens the session to deliver APK data. Note that a session may be opened and closed multiple times as network connectivity changes. The installer may deliver periodic progress updates.
- The installer commits or abandons the session, resulting in the session being finished.

Public methods
onActiveChanged
public abstract void onActiveChanged (int sessionId, boolean active)
Active state for session has been changed.
A session is considered active whenever there is ongoing forward
progress being made, such as the installer holding an open
Session
instance while streaming data into place, or the
system optimizing code as the result of
Session.commit(IntentSender)
.
If the installer closes the Session
without committing, the
session is considered inactive until the installer opens the session
again.

onProgressChanged
public abstract void onProgressChanged (int sessionId, float progress)
Progress for given session has been updated.

, as the
system may carve out a portion of the overall progress to represent
its own internal installation work.
