SharedLibraryInfo

Kotlin |Java

public final class SharedLibraryInfo
extends Object implements Parcelable

java.lang.Object
↳	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.
int	VERSION_UNDEFINED Constant for referring to an undefined version.

Inherited constants

From interface android.os.Parcelable int CONTENTS_FILE_DESCRIPTOR Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor. int PARCELABLE_WRITE_RETURN_VALUE Flag for use with writeToParcel(Parcel, int): the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)".

Fields
public static final Creator<SharedLibraryInfo>	CREATOR

Public methods
int	describeContents() Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
List<String>	getCertDigests() Gets the list of certificate digests for the shared library.
VersionedPackage	getDeclaringPackage() Gets the package that declares the library.
List<VersionedPackage>	getDependentPackages() Gets the packages that depend on the library.
long	getLongVersion() Gets the version of the library.
String	getName() Gets the library name an app defines in its manifest to depend on the library.
int	getType() Gets the type of this library.
int	getVersion() This method was deprecated in API level 28. Use getLongVersion() instead.
String	toString() Returns a string representation of the object.
void	writeToParcel(Parcel parcel, int flags) Flatten this object in to a Parcel.

Inherited methods
From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait(long timeoutMillis, int nanos) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait(long timeoutMillis) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait() Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
From interface android.os.Parcelable abstract int describeContents() Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. abstract void writeToParcel(Parcel dest, int flags) Flatten this object in to a Parcel.

Constants

TYPE_BUILTIN

Added in API level 26

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

Added in API level 26

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

Added in API level 33

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

Added in API level 26

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

Added in API level 26

public static final int VERSION_UNDEFINED

Constant for referring to an undefined version.

Constant Value: -1 (0xffffffff)

Fields

CREATOR

Added in API level 26

public static final Creator<SharedLibraryInfo> CREATOR

Public methods

describeContents

Added in API level 26

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

getCertDigests

Added in Android Baklava

public List<String> getCertDigests ()

Gets the list of certificate digests for the shared library.

Returns
List<String>	The list of certificate digests This value cannot be null.

getDeclaringPackage

Added in API level 26

public VersionedPackage getDeclaringPackage ()

Gets the package that declares the library.

Returns
VersionedPackage	The package declaring the library. This value cannot be null.

getDependentPackages

Added in API level 26

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

Added in API level 28

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

Added in API level 26

public String getName ()

Gets the library name an app defines in its manifest to depend on the library.

Returns
String	The name.

getType

Added in API level 26

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

Added in API level 26
Deprecated in API level 28

public int getVersion ()

This method was deprecated in API level 28.
Use getLongVersion() instead.

Returns
int	Value is -1 or greater

toString

Added in API level 26

public String toString ()

Returns a string representation of the object.

Returns
String	a string representation of the object.

writeToParcel

Added in API level 26

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
