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
PackageInstaller.Session instance while streaming data into place, or the
system optimizing code as the result of
commit(IntentSender).
If the installer closes the PackageInstaller.Session without committing, the
session is considered inactive until the installer opens the session
again.

int

void onProgressChanged (int sessionId,
float progress)

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