Public methods

onActiveChanged

Added in API level 21
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.

Parameters
sessionId int
active boolean

onBadgingChanged

Added in API level 21
void onBadgingChanged (int sessionId)

Badging details for an existing session has changed. For example, the app icon or label has been updated.

Parameters
sessionId int

onCreated

Added in API level 21
void onCreated (int sessionId)

New session has been created. Details about the session can be obtained from getSessionInfo(int).

Parameters
sessionId int

onFinished

Added in API level 21
void onFinished (int sessionId, 
                boolean success)

Session has completely finished, either with success or failure.

onProgressChanged

Added in API level 21
void onProgressChanged (int sessionId, 
                float progress)

Note that this progress may not directly correspond to the value reported by setStagingProgress(float), as the system may carve out a portion of the overall progress to represent its own internal installation work.

Parameters
sessionId int
progress float
