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 API level 36

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
