<init>

CustomTabsService()

Abstract service class for implementing Custom Tabs related functionality. The service should be responding to the action ACTION_CUSTOM_TABS_CONNECTION. This class should be used by implementers that want to provide Custom Tabs functionality, not by clients that want to launch Custom Tabs.

onBind

@NonNull open fun onBind(@Nullable intent: Intent?): IBinder

cleanUpSession

protected open fun cleanUpSession(@NonNull sessionToken: CustomTabsSessionToken): Boolean

Called when the client side IBinder for this CustomTabsSessionToken is dead. Can also be used to clean up DeathRecipient instances allocated for the given token.

extraCommand

@Nullable protected abstract fun extraCommand(@NonNull commandName: String, @Nullable args: Bundle?): Bundle?

Unsupported commands that may be provided by the implementation.

Note:Clients should never rely on this method to have a defined behavior, as it is entirely implementation-defined and not supported.

This call can be used by implementations to add extra commands, for testing or experimental purposes.

mayLaunchUrl

protected abstract fun mayLaunchUrl(@NonNull sessionToken: CustomTabsSessionToken, @NonNull url: Uri, @Nullable extras: Bundle?, @Nullable otherLikelyBundles: MutableList<Bundle!>?): Boolean

Tells the browser of a likely future navigation to a URL.

The method CustomTabsService#warmup(long) has to be called beforehand. The most likely URL has to be specified explicitly. Optionally, a list of other likely URLs can be provided. They are treated as less likely than the first one, and have to be sorted in decreasing priority order. These additional URLs may be ignored. All previous calls to this method will be deprioritized.

newSession

protected abstract fun newSession(@NonNull sessionToken: CustomTabsSessionToken): Boolean

Creates a new session through an ICustomTabsService with the optional callback. This session can be used to associate any related communication through the service with an intent and then later with a Custom Tab. The client can then send later service calls or intents to through same session-intent-Custom Tab association.

postMessage

protected abstract fun postMessage(@NonNull sessionToken: CustomTabsSessionToken, @NonNull message: String, @Nullable extras: Bundle?): Int

Sends a postMessage request using the origin communicated via CustomTabsService#requestPostMessageChannel( *CustomTabsSessionToken, Uri). Fails when called before PostMessageServiceConnection#notifyMessageChannelReady(Bundle) is received on the client side.

receiveFile

protected abstract fun receiveFile(@NonNull sessionToken: CustomTabsSessionToken, @NonNull uri: Uri, purpose: Int, @Nullable extras: Bundle?): Boolean

Receive a file from client by given Uri, e.g. in order to display a large bitmap in a Custom Tab. Prior to calling this method, the client grants a read permission to the target Custom Tabs provider via android.content.Context#grantUriPermission. The file is read and processed (where applicable) synchronously.

requestPostMessageChannel

protected abstract fun requestPostMessageChannel(@NonNull sessionToken: CustomTabsSessionToken, @NonNull postMessageOrigin: Uri): Boolean

Sends a request to create a two way postMessage channel between the client and the browser linked with the given CustomTabsSession.

updateVisuals

protected abstract fun updateVisuals(@NonNull sessionToken: CustomTabsSessionToken, @Nullable bundle: Bundle?): Boolean

Updates the visuals of custom tabs for the given session. Will only succeed if the given session matches the currently active one.

validateRelationship

protected abstract fun validateRelationship(@NonNull sessionToken: CustomTabsSessionToken, relation: Int, @NonNull origin: Uri, @Nullable extras: Bundle?): Boolean

Request to validate a relationship between the application and an origin. If this method returns true, the validation result will be provided through CustomTabsCallback#onRelationshipValidationResult(int, Uri, boolean, Bundle). Otherwise the request didn't succeed. The client must call CustomTabsClient#warmup(long) before this.

warmup

protected abstract fun warmup(flags: Long): Boolean

Warms up the browser process asynchronously.
