↳ | android.content.pm.SharedLibraryInfo |
This class provides information for a shared library. There are four types of shared libraries: builtin - non-updatable part of the OS; dynamic - updatable backwards-compatible dynamically linked; static - non backwards-compatible emulating static linking; SDK - updatable backwards-incompatible dynamically loaded.
Summary
Constants | |
---|---|
int |
TYPE_BUILTIN
Shared library type: this library is a part of the OS and cannot be updated or uninstalled. |
int |
TYPE_DYNAMIC
Shared library type: this library is backwards-compatible, can be updated, and updates can be uninstalled. |
int |
TYPE_SDK_PACKAGE
SDK package shared library type: this library is not compatible between versions, can be updated and updates can be uninstalled. |
int |
TYPE_STATIC
Shared library type: this library is not backwards -compatible, can be updated and updates can be uninstalled. |

Constants
TYPE_BUILTIN
public static final int TYPE_BUILTIN
Shared library type: this library is a part of the OS and cannot be updated or uninstalled.
Constant Value: 0 (0x00000000)
TYPE_DYNAMIC
public static final int TYPE_DYNAMIC
Shared library type: this library is backwards-compatible, can be updated, and updates can be uninstalled. Clients link against the latest version of the library.
Constant Value: 1 (0x00000001)
TYPE_SDK_PACKAGE
public static final int TYPE_SDK_PACKAGE
SDK package shared library type: this library is not compatible between versions, can be updated and updates can be uninstalled. Clients depend on a specific version of the library. SDK packages are not loaded automatically by the OS and rely e.g. on 3P libraries to make them available for the clients.
Constant Value: 3 (0x00000003)
TYPE_STATIC
public static final int TYPE_STATIC
Shared library type: this library is not backwards -compatible, can be updated and updates can be uninstalled. Clients link against a specific version of the library. Static shared libraries simulate static linking while allowing for multiple clients to reuse the same instance of the library.
Constant Value: 2 (0x00000002)
VERSION_UNDEFINED
public static final int VERSION_UNDEFINED
Constant for referring to an undefined version.
Constant Value: -1 (0xffffffff)
Fields
Public methods
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.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled
by this Parcelable object instance.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
getDeclaringPackage
public VersionedPackage getDeclaringPackage ()
Gets the package that declares the library.
Returns | |
---|---|
VersionedPackage |
The package declaring the library.
This value cannot be null . |
getDependentPackages
public List<VersionedPackage> getDependentPackages ()
Gets the packages that depend on the library.
NOTE: the list also contains the result of ERROR(/#getOptionalDependentPackages)
.
Returns | |
---|---|
List<VersionedPackage> |
The dependent packages.
This value cannot be null . |
getLongVersion
public long getLongVersion ()
Gets the version of the library. For static
libraries
this is the declared version and for dynamic
and
builtin
it is VERSION_UNDEFINED
as these
are not versioned.
Returns | |
---|---|
long |
The version. Value is -1 or greater |
getName
public String getName ()
Gets the library name an app defines in its manifest to depend on the library.
Returns | |
---|---|
String |
The name. |
getType
public int getType ()
Gets the type of this library.
Returns | |
---|---|
int |
The library type.
Value is either 0 or a combination of TYPE_BUILTIN , TYPE_DYNAMIC , TYPE_STATIC , and TYPE_SDK_PACKAGE |
getVersion
public int getVersion ()
This method was deprecated
in API level 28.
Use getLongVersion()
instead.
Returns | |
---|---|
int |
Value is -1 or greater |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
writeToParcel
public void writeToParcel (Parcel parcel, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
parcel |
Parcel : The Parcel in which the object should be written.
This value cannot be null . |
flags |
int : Additional flags about how the object should be written.
May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE .
Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
