PackageInstaller

public class PackageInstaller
extends Object

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


Offers the ability to install, upgrade, and remove applications on the device. This includes support for apps packaged either as a single "monolithic" APK, or apps packaged as multiple "split" APKs.

An app is delivered for installation through a PackageInstaller.Session, which any app can create. Once the session is created, the installer can stream one or more APKs into place until it decides to either commit or destroy the session. Committing may require user intervention to complete the installation, unless the caller falls into one of the following categories, in which case the installation will complete automatically.

  • the device owner
  • the affiliated profile owner

Sessions can install brand new apps, upgrade existing apps, or add new splits into an existing app.

Apps packaged as multiple split APKs always consist of a single "base" APK (with a null split name) and zero or more "split" APKs (with unique split names). Any subset of these APKs can be installed together, as long as the following constraints are met:

  • All APKs must have the exact same package name, version code, and signing certificates.
  • All APKs must have unique split names.
  • All installations must contain a single base APK.

The ApiDemos project contains examples of using this API: ApiDemos/src/com/example/android/apis/content/InstallApk*.java.

User action is currently required to proceed. You can launch the intent activity described by Intent#EXTRA_INTENT to involve the user and continue.

The operation succeeded.

Constant Value: 0 (0x00000000)

Public methods

abandonSession

Added in API level 21
public void abandonSession (int sessionId)

Completely abandon the given session, destroying all staged data and rendering it invalid. Abandoned sessions will be reported to SessionCallback listeners as failures. This is equivalent to opening the session and calling Session#abandon().

Parameters
sessionId int

Throws
SecurityException when the caller does not own the session, or the session is invalid.

checkInstallConstraints

Added in API level 34
public void checkInstallConstraints (List<String> packageNames, 
                PackageInstaller.InstallConstraints constraints, 
                Executor executor, 
                Consumer<PackageInstaller.InstallConstraintsResult> callback)

Check if install constraints are satisfied for the given packages. Note this query result is just a hint and subject to race because system states could change anytime in-between this query and committing the session. The result is returned by a callback because some constraints might take a long time to evaluate.

Parameters
packageNames List: a list of package names to check the constraints for installation This value cannot be null.

constraints PackageInstaller.InstallConstraints: the constraints for installation. This value cannot be null.

executor Executor: the Executor on which to invoke the callback This value cannot be null. Callback and listener events are dispatched through this Executor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use Context.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread.

callback Consumer: called when the InstallConstraintsResult is ready This value cannot be null.

Throws
SecurityException if the given packages' installer of record doesn't match the caller's own package name or the installerPackageName set by the caller doesn't match the caller's own package name.

commitSessionAfterInstallConstraintsAreMet

Added in API level 34
public void commitSessionAfterInstallConstraintsAreMet (int sessionId, 
                IntentSender statusReceiver, 
                PackageInstaller.InstallConstraints constraints, 
                long timeoutMillis)

Commit the session when all constraints are satisfied. This is a convenient method to combine waitForInstallConstraints(java.util.List, android.content.pm.PackageInstaller.InstallConstraints, android.content.IntentSender, long) and Session#commit(IntentSender).

Once this method is called, the session is sealed and no additional mutations may be performed on the session. In the case of timeout, you may commit the session again using this method or Session#commit(IntentSender) for retries.

Parameters
sessionId int: the session ID to commit when all constraints are satisfied.

statusReceiver IntentSender: Called when the state of the session changes. Intents sent to this receiver contain EXTRA_STATUS. Refer to the individual status codes on how to handle them. This value cannot be null.

constraints PackageInstaller.InstallConstraints: The requirements to satisfy before committing the session. This value cannot be null.

timeoutMillis long: The maximum time to wait, in milliseconds until the constraints are satisfied. The caller will be notified via statusReceiver if timeout happens before commit. Value is a non-negative duration in milliseconds.

Throws
IllegalArgumentException if the statusReceiver from an immutable PendingIntent when caller has a target SDK of API 35 or above.

createSession

Added in API level 21
public int createSession (PackageInstaller.SessionParams params)

Create a new session using the given parameters, returning a unique ID that represents the session. Once created, the session can be opened multiple times across multiple device boots.

The system may automatically destroy sessions that have not been finalized (either committed or abandoned) within a reasonable period of time, typically on the order of a day.

Parameters
params PackageInstaller.SessionParams: This value cannot be null.

Returns
int positive, non-zero unique ID that represents the created session. This ID remains consistent across device reboots until the session is finalized. IDs are not reused during a given boot.

SecurityException when installation services are unavailable, such as when called from a restricted user.
IllegalArgumentException when SessionParams is invalid.
