/**
 * 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.
 * <p>
 * An app is delivered for installation through a
 * {@link 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>
 * <p>
 * Sessions can install brand new apps, upgrade existing apps, or add new splits
 * into an existing app.
 * <p>
 * Apps packaged as multiple split APKs always consist of a single "base" APK
 * (with a {@code 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>
 * <p>
 * The ApiDemos project contains examples of using this API:
 * <code>ApiDemos/src/com/example/android/apis/content/InstallApk*.java</code>.
