Remarks

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. <ul> <li>the device owner <li>the affiliated profile owner </ul>

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: <ul> <li>All APKs must have the exact same package name, version code, and signing certificates. <li>All APKs must have unique split names. <li>All installations must contain a single base APK. </ul>

Constructors

PackageInstaller(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Fields

ActionSessionCommitted	Broadcast Action: Explicit broadcast sent to the last known default launcher when a session for a new install is committed.
ActionSessionDetails	Activity Action: Show details about a particular install session.
ActionSessionUpdated	Broadcast Action: Send information about a staged install session when its state is updated.
ExtraInstallConstraints	The `InstallConstraints` object.
ExtraInstallConstraintsResult	The `InstallConstraintsResult` object.
ExtraOtherPackageName	Another package name relevant to a status.
ExtraPackageName	Package name that an operation is working with.
ExtraPreApproval	Indicate if the status is for a pre-approval request.
ExtraSession	`SessionInfo` that an operation is working with.
ExtraSessionId	An integer session ID that an operation is working with.
ExtraStatus	Current status of an operation.
ExtraStatusMessage	Detailed string representation of the status, including raw details that are useful for debugging.
ExtraStoragePath	Storage path relevant to a status.
PackageSourceDownloadedFile	Obsolete. Code indicating that the package being installed comes from a file that was downloaded to the device by the user.
PackageSourceLocalFile	Obsolete. Code indicating that the package being installed comes from a local file on the device.
PackageSourceOther	Obsolete. Code indicating that the package being installed is from a source not reflected by any other package source constant.
PackageSourceStore	Obsolete. Code indicating that the package being installed is from a store.
PackageSourceUnspecified	Obsolete. The installer did not call `PackageInstaller.SessionParams#setPackageSource(int)` to specify the package source.
StatusFailureTimeout	Obsolete. The operation failed because it didn't complete within the specified timeout.
