Summary

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<ApkChecksum>`	`CREATOR`

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`Certificate`	`getInstallerCertificate()` For Installer-provided checksums, certificate of the Installer.
`String`	`getInstallerPackageName()` For Installer-provided checksums, package name of the Installer.
`String`	`getSplitName()` Checksum for which split.
`int`	`getType()` Checksum type.
`byte[]`	`getValue()` Checksum value.
`String`	`toString()` Returns a string representation of the object.
`void`	`writeToParcel(Parcel dest, 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.

Fields

CREATOR

Added in API level 31

public static final Creator<ApkChecksum> CREATOR

Public methods

describeContents

Added in API level 31

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`

getInstallerCertificate

Added in API level 31

public Certificate getInstallerCertificate ()

For Installer-provided checksums, certificate of the Installer.

Returns
`Certificate`	This value may be `null`.

Throws
`CertificateException`	in case when certificate can't be re-created from serialized data.

getInstallerPackageName

Added in API level 31

public String getInstallerPackageName ()

For Installer-provided checksums, package name of the Installer.

Returns
`String`	This value may be `null`.

getSplitName

Added in API level 31

public String getSplitName ()

Checksum for which split. Null indicates base.apk.

Returns
`String`	This value may be `null`.

getType

Added in API level 31

public int getType ()

Checksum type.

Returns
`int`	Value is `Checksum.TYPE_WHOLE_MERKLE_ROOT_4K_SHA256`, `Checksum.TYPE_WHOLE_MD5`, `Checksum.TYPE_WHOLE_SHA1`, `Checksum.TYPE_WHOLE_SHA256`, `Checksum.TYPE_WHOLE_SHA512`, `Checksum.TYPE_PARTIAL_MERKLE_ROOT_1M_SHA256`, or `Checksum.TYPE_PARTIAL_MERKLE_ROOT_1M_SHA512`

getValue

Added in API level 31

public byte[] getValue ()

Checksum value.

Returns
`byte[]`	This value cannot be `null`.

toString

Added in API level 31

public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.

writeToParcel

Added in API level 31

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: 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
