SharedLibraryInfo
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
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 |
getCertDigests
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
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 |
