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.
`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

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`

getInstallerCertificate

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

public String getInstallerPackageName ()

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

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

getSplitName

public String getSplitName ()

Checksum for which split. Null indicates base.apk.

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

getType

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

public byte[] getValue ()

Checksum value.

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

writeToParcel

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
