/**
* @hide Install a package. Since this may take a little while, the result
*       will be posted back to the given observer. An installation will
*       fail if the calling context lacks the
*       {@link android.Manifest.permission#INSTALL_PACKAGES} permission, if
*       the package named in the package file's manifest is already
*       installed, or if there's no space available on the device.
* @param packageURI The location of the package file to install. This can
*            be a 'file:' or a 'content:' URI.
* @param observer An observer callback to get notified when the package
*            installation is complete.
*            {@link IPackageInstallObserver#packageInstalled(String, int)}
*            will be called when that happens. This parameter must not be
*            null.
* @param flags - possible values: {@link #INSTALL_FORWARD_LOCK},
*            {@link #INSTALL_REPLACE_EXISTING},
*            {@link #INSTALL_ALLOW_TEST}.
* @param installerPackageName Optional package name of the application that
*            is performing the installation. This identifies which market
*            the package came from.
* @deprecated Use {@link #installPackage(Uri, PackageInstallObserver, int,
*             String)} instead. This method will continue to be supported
*             but the older observer interface will not get additional
*             failure details.
