The Google Assistant plugin is used to test App Actions within Android Studio. During development and testing, you use the plugin to create a preview of your App Actions in Assistant (for your Google account). You can then test how your App Action handles various parameters prior to submitting it for deployment.
How it works
The Google Assistant plugin includes the App Actions Test Tool, a feature that
shortcuts.xml file and creates a preview of your App Actions for a
single Google account. These previews enable Google Assistant to recognize your
App Actions prior to deploying the production version of your app to the Google
For each built-in intent (BII) in your
shortcuts.xml file, the tool renders
a corresponding JSON-LD object and provides default parameter values. You can
then modify those values to test your App Actions with meaningful parameter
combinations and ensure they perform the correct app functions. Previews can be
created, updated, and deleted in the test tool, allowing you to iterate and
test your App Actions in a safe environment.
Once a preview is created, you can trigger an App Action on your test device
directly from the test tool window. For built-in intents that are available
for user triggering, you can use the
app name directly in Assistant on your
device to try out your App Action. For example, you could say, "Hey Google,
start my exercise using ExampleApp" to launch an App Action that uses the
actions.intent.START_EXERCISE built-in intent.
Creating previews for specific locales in the test tool varies by built-in intent (BII). The page for each BII in the built-in intent reference provides information on what functionality is available for that built-in intent, like the locales where preview creation in the test tool is available. For example, whether the test tool supports creating previews for a specific locale, and whether App Actions are available for users to trigger.
Get the plugin
The Google Assistant plugin is available for Android Studio. For information about installing and using Android Studio, see the Android Studio page.
To install the Google Assistant plugin in Android Studio, follow these steps:
- Go to File > Settings (Android Studio > Preferences on MacOS).
- In the Plugins section, go to Marketplace and search for
Google Assistant plugin.
- Install the tool and restart Android Studio.
You can also download the plugin directly from the Jetbrains public repository.
Using the Google Assistant plugin requires a number of configuration steps to allow your Action to be successfully tested. In particular, you must use the same user account in Android Studio, on your test device, and for Google Play console access.
Prepare your development environment with the following configurations:
- Sign in to Android Studio (version 4.0 or higher).
- With the same account, sign in to the Google app on your Android test device.
- With the same account, get Play Console access to the uploaded app package to be tested.
- Open the Google app on your Android test device and finish the initial Assistant setup process.
- Enable device data syncing on your test device.
The Google Assistant plugin has the following limitations:
- App Actions that incorporate web inventory and foreground app invocation cannot be tested directly in the test tool or by Android debug bridge (adb) commands. To test those App Actions, first create a preview using the test tool. Then, trigger those App Actions by interacting with Google Assistant on your physical device.
- Inline inventory for the
actions.intent.OPEN_APP_FEATUREbuilt-in intent can only be tested for a period of 6 hours after a preview is created or updated. Update the test tool preview or create a new preview to reset the 6 hour time period.
Add additional testers
You can invite additional users to your project so they can test your App Actions integration. This is useful when you want to share the project with other members of your development team so they can all test, or when sharing your project with quality assurance (QA) testers in preparation for production launch. Testers must be added as license testers on the Google Play Store and granted read-only access to Google Play Console.
To add additional testers, follow these steps:
- Sign in to the Play Console.
Follow the instructions under 'Set up application licensing' in this Play Console Help topic.
Grant the license tester’s Gmail account as a Google Play Console read-only user.
- Select User & permissions > Invite new users > Add app.
- In App Access, ensure the Admin (all permissions) checkbox is cleared.
For each tester that you want to enable for preview testing, you must log in separately to Android Studio with that user's Gmail account. Once logged in, use the Google Assistant plugin to create a preview for the test user.
Use the Google Assistant plugin
Access the App Actions Test Tool in Android Studio by going to Tools > Google Assistant > App Actions test tool. When you open the tool, the view changes based on if you have an active test tool preview.
Create, update, and delete previews
You can use a draft version of the app for testing. For more information, see Prepare and roll out a release. We strongly encourage you to test your app in draft mode before submitting it for review.
The test tool creates previews based on your Google account and app package name (application ID), so you can test multiple apps with the same Google account. As long as your application ID is different for each app, you can continue to use the same Google account for preview creation and testing. Multiple Google accounts with access to the same app package can each use the test tool to create separate previews for that app.
To create a preview, do the following in Android Studio:
- Open the App Actions test tool.
- Optionally enter an app name and locale for testing. The default
app name and locale are
test app actionand
- Click Create Preview. If asked, review and accept the App Actions
policies and terms of service. Once your preview is created, the test tool
window updates to display information about BIIs found in your
The test tool uses the app name to construct and simulate Assistant queries for your App Actions. Deployed App Actions use your Play Store app name for invocation, but you can use any invocation name in the test tool. We recommend using the name of your app as your invocation name in the test tool.
The locale you provide must match the language of Google Assistant on your
test device, and you can only create a preview in one locale at a time. For
example, if your Assistant language is English (US), you can enter
en-US, en-GB. You can also use a root locale, such
en, to include both
To change the app name or selected locale for an existing preview, click the Delete button in the test tool. Then, enter the desired app name and locale before creating a new preview.
To update an existing preview to match your
shortcuts.xml file, click the
Update button in the test tool. Information about your current
preview is in the Test App Action section of the test tool window.
Configure a built-in intent
Once you've created a preview for your app, you can test various parameter
values for built-in intents in the plugin. For each BII in your
shortcuts.xml file, the plugin renders a corresponding
JSON-LD object and provides default parameter values. You can modify those
default values to test your App Actions with meaningful parameter combinations
and ensure they perform the correct app functions.
Parameters and their values typically follow the
schema.googleapis.com structure for properties and descriptions. You can find
information about any given built-in intent parameter by accessing the schema
type descriptions of a parameter and its higher level parameters as labeled.
For example, the
actions.intent.CREATE_MONEY_TRANSFER built-in intent
supports the intent parameter
schema.googleapis.com page for
transferMode as a
transferMode property is a mode of transfer, and it expects
SendMoney) of the enumerated
FinancialTransferMode type. In the
test tool, you can provide either of the enumerations as the value of
Trigger App Actions
After creating a preview and configuring a built-in intent, you can trigger an App Action on your test device directly from the test tool window.
To trigger an App Action with the test tool, do the following:
- Connect your test device.
- In the Select Target Device section, choose the device where you want to trigger your App Action.
- In the Test App Action section, click the Run App Action button.
App Actions triggered in the test tool use the displayed Android Debug Bridge (adb) command. The generated adb shell command includes all the metadata required by the Google app to execute a built-in intent. This approach mimics the behavior of your App Action after Assistant extracts key pieces of information from a query.
Android Studio logging
Logs specific to the test tool are available in the Android Studio log files, not as Logcat output. Android Studio logs are generated by processes running directly on your workstation, and you can use them to troubleshoot test tool operations like creating, updating, or deleting a preview.
To access your Android Studio log files, go to Help > Show log in explorer (Help > Show log in finder on MacOS).
Logs related to App Actions for your app are available in Logcat. Logcat captures logs from virtual or physical devices connected to Android Studio.
To get App Actions logs for your device, follow these steps:
- Access your Logcat log messages by clicking Logcat in the Android Studio tool window bar.
- Search for logs that include
