PackageInstaller.SessionCallback

Kotlin |Java

public static abstract class PackageInstaller.SessionCallback
extends Object

java.lang.Object
↳	android.content.pm.PackageInstaller.SessionCallback

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.

`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Public methods

onActiveChanged

Added in API level 21

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.

Parameters
`sessionId`	`int`
`active`	`boolean`

onBadgingChanged

Added in API level 21

public abstract 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

public abstract void onCreated (int sessionId)

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

Parameters
`sessionId`	`int`

onFinished

Added in API level 21

public abstract void onFinished (int sessionId, 
                boolean success)

Session has completely finished, either with success or failure.

Parameters
`sessionId`	`int`
`success`	`boolean`

onProgressChanged

Added in API level 21

public abstract void onProgressChanged (int sessionId, 
                float progress)

Progress for given session has been updated.

Note that this progress may not directly correspond to the value reported by PackageInstaller.Session.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`
