TrustedWebActivityService

Kotlin |Java

public abstract class TrustedWebActivityService
extends Service

java.lang.Object
↳	android.content.Context
	↳	android.content.ContextWrapper
		↳	android.app.Service
			↳	androidx.browser.trusted.TrustedWebActivityService

The TrustedWebActivityService lives in a client app and serves requests from a Trusted Web Activity provider. At present it only serves requests to do with notifications.

When the provider receives a notification from a scope that is associated with a Trusted Web Activity client app, it will attempt to connect to a TrustedWebActivityService and forward calls. This allows the client app to display the notifications itself, meaning it is attributable to the client app and is managed by notification permissions of the client app, not the provider.

TrustedWebActivityService is usable as it is, by adding the following to your AndroidManifest:

 <service
     android:name="androidx.browser.trusted.TrustedWebActivityService"
     android:enabled="true"
     android:exported="true">

     <meta-data android:name="android.support.customtabs.trusted.SMALL_ICON"
         android:resource="@drawable/ic_notification_icon" />

     <intent-filter>
         <action android:name="android.support.customtabs.trusted.TRUSTED_WEB_ACTIVITY_SERVICE"/>
         <category android:name="android.intent.category.DEFAULT"/>
     </intent-filter>
 </service>

The SMALL_ICON resource should point to a drawable to be used for the notification's small icon.

Alternatively for greater customization, TrustedWebActivityService can be extended and overridden. In this case the manifest entry should be updated to point to the extending class.

As this is an AIDL Service, calls may come in from different Binder threads, so overriding implementations need to be thread safe [1].

For security, the TrustedWebActivityService will check that whatever connects to it matches the Token stored in the TokenStore returned by getTokenStore(). This is because we don't want to allow any app on the users device to connect to this Service be able to make it display notifications. [1]: https://developer.android.com/guide/components/aidl.html

Summary

Constants
`String`	`ACTION_TRUSTED_WEB_ACTIVITY_SERVICE` An Intent Action used by the provider to find the TrustedWebActivityService or subclass.
`String`	`KEY_SMALL_ICON_BITMAP` The key to use to store a Bitmap to return from the `onGetSmallIconBitmap()` method.
`String`	`KEY_SUCCESS` The key to use to store a boolean in the returns bundle of `onExtraCommand(String, Bundle, TrustedWebActivityCallbackRemote)` method, to indicate whether the command is executed successfully.
`String`	`META_DATA_NAME_SMALL_ICON` The Android Manifest meta-data name to specify a small icon id to use.
`int`	`SMALL_ICON_NOT_SET` Used as a return value of `onGetSmallIconId()` when the icon is not provided.

`platformId`	`int`: The notification id, see `NotificationManager.cancel(String, int)`.

onCreate

public void onCreate ()

Called by the system when the service is first created. Do not call this method directly. Overrides must call super.onCreate().

onExtraCommand

public Bundle onExtraCommand (String commandName, 
                Bundle args, 
                TrustedWebActivityCallbackRemote callbackRemote)

Contains a free form command from the browser. The client and browser will need to agree on an additional API to use in advanced. This call can be used for testing or experimental purposes. A return value of null will be used to signify that the client does not know how to handle the request. As optional best practices, KEY_SUCCESS could be use to identify that command was *successfully* handled. For example, when returning a message with result:


     Bundle result = new Bundle();
     result.putString("message", message);
     if (success)
         result.putBoolean(KEY_SUCCESS, true);
     return result;

On the caller side:


     Bundle result = service.extraCommand(commandName, args);
     if (result.getBoolean(service.KEY_SUCCESS)) {
         // Command was successfully handled
     }

Parameters
`commandName`	`String`: Name of the command to execute.
`args`	`Bundle`: Arguments to the command.
`callbackRemote`	`TrustedWebActivityCallbackRemote`: Contains the callback that passed with the command.

Returns
`Bundle`	The result `Bundle` or `null`.

onGetSmallIconId

public int onGetSmallIconId ()

Returns the Android resource id of a drawable to be used for the small icon of the notification. This is called by the provider as it is constructing the notification so a complete notification can be passed to the client.

Returns
`int`	A resource id for the small icon, or `SMALL_ICON_NOT_SET` if not found.
