Token

Kotlin |Java

public final class Token
extends Object

java.lang.Object
↳	androidx.browser.trusted.Token

Stores a package's identity, a combination of its package name and signing certificate. It is designed to be persistable as a byte[], so you can do this:

 Token token = Token.create(packageName, packageManager);
 byte[] serialized = token.serialize();
 // Persist serialized.

 // Some time later...
 Token verified = Token.deserialize(serialized);
 verified.matches(packageName, packageManager);

Summary

Public methods
`static Token`	`create(String packageName, PackageManager packageManager)` Creates a `Token` for the given package, taking into account the package name and its signing signature.
`static Token`	`deserialize(byte[] serialized)` Reconstructs a `Token` from the output of its `serialize()`.
`boolean`	`matches(String packageName, PackageManager packageManager)` Whether the given package matches the package that was used to create the original Token.
`byte[]`	`serialize()` Serializes the `Token` to a form that can later be restored by the `deserialize(byte[])` method.

Public methods

create

public static Token create (String packageName, 
                PackageManager packageManager)

Creates a Token for the given package, taking into account the package name and its signing signature.

Parameters
`packageName`	`String`: The name of the package.
`packageManager`	`PackageManager`: A `PackageManager` to determine the signing information.

Returns
`Token`	A `Token`. `null` if the provided package cannot be found (the app is not installed).

deserialize

public static Token deserialize (byte[] serialized)

Reconstructs a Token from the output of its serialize().

Parameters
`serialized`	`byte`: The result of a `serialize()` call.

Returns
`Token`	The deserialized Token.

matches

public boolean matches (String packageName, 
                PackageManager packageManager)

Whether the given package matches the package that was used to create the original Token.

Parameters
`packageName`	`String`: The name of the package.
`packageManager`	`PackageManager`: A `PackageManager` to get information about the package.

Returns
`boolean`	Whether the given package currently is the same as the one used to create the Token.

serialize

public byte[] serialize ()

Serializes the Token to a form that can later be restored by the deserialize(byte[]) method.

Returns
`byte[]`	A serialization of the `Token`.
