PackageInstaller.SessionParams

MODE_FULL_INSTALL

public static final int MODE_FULL_INSTALL

Mode for an install session whose staged APKs should fully replace any existing APKs for the target app.

Constant Value: 1 (0x00000001)

MODE_INHERIT_EXISTING

public static final int MODE_INHERIT_EXISTING

Mode for an install session that should inherit any existing APKs for the target app, unless they have been explicitly overridden (based on split name) by the session. For example, this can be used to add one or more split APKs to an existing installation.

If there are no existing APKs for the target app, this behaves like MODE_FULL_INSTALL.

Constant Value: 2 (0x00000002)

CREATOR

public static final Creator<PackageInstaller.SessionParams> CREATOR

RESTRICTED_PERMISSIONS_ALL

public static final Set<String> RESTRICTED_PERMISSIONS_ALL

Special constant to refer to all restricted permissions.

SessionParams

public SessionParams (int mode)

Construct parameters for a new package install session.

describeContents

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

setAppIcon

public void setAppIcon (Bitmap appIcon)

Optionally set an icon representing the app being installed. This should be roughly ActivityManager#getLauncherLargeIconSize() in both dimensions.

setAppLabel

public void setAppLabel (CharSequence appLabel)

Optionally set a label representing the app being installed. This value will be trimmed to the first 1000 characters.

setAppPackageName

public void setAppPackageName (String appPackageName)

Optionally set the package name of the app being installed. It's strongly recommended that you provide this value when known, so that observers can communicate installing apps to users.

If the APKs staged in the session aren't consistent with this package name, the install will fail. Regardless of this value, all APKs in the app must have the same package name.

setAutoRevokePermissionsMode

public void setAutoRevokePermissionsMode (boolean shouldAutoRevoke)

Sets whether permissions should be auto-revoked if this package is unused for an extended periodd of time. It's disabled by default but generally the installer should enable it for most packages, excluding only those where doing so might cause breakage that cannot be easily addressed by simply re-requesting the permission(s). If user explicitly enabled or disabled it via settings, this call is ignored.

setInstallLocation

public void setInstallLocation (int installLocation)

Provide value of PackageInfo#installLocation, which may be used to determine where the app will be staged. Defaults to PackageInfo#INSTALL_LOCATION_INTERNAL_ONLY.

setInstallReason

public void setInstallReason (int installReason)

Set the reason for installing this package.

The install reason should be a pre-defined integer. The behavior is undefined if other values are used.

setMultiPackage

public void setMultiPackage ()

Set this session to be the parent of a multi-package install. A multi-package install session contains no APKs and only references other install sessions via ID. When a multi-package session is committed, all of its children are committed to the system in an atomic manner. If any children fail to install, all of them do, including the multi-package session.

setOriginatingUid

public void setOriginatingUid (int originatingUid)

Sets the UID that initiated the package installation. This is informational and may be used as a signal for anti-malware purposes.

setOriginatingUri

public void setOriginatingUri (Uri originatingUri)

Optionally set the URI where this package was downloaded from. This is informational and may be used as a signal for anti-malware purposes.

setReferrerUri

public void setReferrerUri (Uri referrerUri)

Optionally set the URI that referred you to install this package. This is informational and may be used as a signal for anti-malware purposes.

setSize

public void setSize (long sizeBytes)

Optionally indicate the total size (in bytes) of all APKs that will be delivered in this session. The system may use this to ensure enough disk space exists before proceeding, or to estimate container size for installations living on external storage.

setWhitelistedRestrictedPermissions

public void setWhitelistedRestrictedPermissions (Set<String> permissions)

Sets which restricted permissions to be whitelisted for the app. Whitelisting is not granting the permissions, rather it allows the app to hold permissions which are otherwise restricted. Whitelisting a non restricted permission has no effect.

Permissions can be hard restricted which means that the app cannot hold them or soft restricted where the app can hold the permission but in a weaker form. Whether a permission is PermissionInfo#FLAG_HARD_RESTRICTED or PermissionInfo#FLAG_SOFT_RESTRICTED depends on the permission declaration. Whitelisting a hard restricted permission allows the app to hold that permission and whitelisting a soft restricted permission allows the app to hold the permission in its full, unrestricted form.

Permissions can also be immutably restricted which means that the whitelist state of the permission can be determined only at install time and cannot be changed on updated or at a later point via the package manager APIs.

Initially, all restricted permissions are whitelisted but you can change which ones are whitelisted by calling this method or the corresponding ones on the PackageManager. Only soft or hard restricted permissions on the current Android version are supported and any invalid entries will be removed.

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.
