The App Actions test tool is an Android Studio plugin for developers creating App Actions. During development and testing, you use the App Actions test tool to create a preview of your App Actions in the Assistant (for your Google account). You can then test how your App Action handles various parameters prior to submitting it for deployment.
What it does
The App Actions test tool parses your
actions.xml file and
creates a preview of your App Actions for a single Google account. These
previews enable the Assistant to recognize your App Actions prior to deploying
the production version of your app to the Google Play Console.
For each built-in intent (BII) in your
actions.xml file, the plugin 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 generated, 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 also use the invocation name directly in the 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
actions.intent.START_EXERCISE built-in intent.
The App Actions test tool supports the en-US, en-GB, en-CA, en-IN, en-BE, en-SG, and en-AU locales for preview creation. Other locales are only supported for preview creation in certain built-in intent categories:
|Built-in intent category||Additional locale support|
|Finance||es-ES, es-MX, pt-BR|
|Food and drink||es-ES, es-MX, id-ID, pt-BR|
Getting the tool
To install the App Actions test tool in Android Studio:
- Go to File > Settings (Android Studio > Preferences on MacOS).
- In the Plugins section, go to Marketplace and search for
App Actions Test Tool.
- Install the tool and restart Android Studio.
You can also download the plugin directly from the Jetbrains public repository.
To use the tool, you must do the following:
- Sign in to Android Studio (version 3.4 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 App Actions test tool has the following limitations:
- App Action previews are only accessible on physical devices. Attempts to trigger an App Action preview on a virtual device are likely to result in the message "Sorry, I couldn't find that".
- Testing previews is not supported on Google Pixel 4 devices and other devices using the new Google Assistant.
- 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.
Using the tool
Access the App Actions test tool in Android Studio by going to Tools > App Actions Test Tool or by selecting App Actions Test Tool in the right-click context menu. When you open the tool, the view may be slightly different depending on whether you have an active test tool preview or not.
Creating, updating, and deleting previews
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.
If you don't have an active preview, then you must create one before you can use the plugin for testing your App Action. To create a preview, do the following in Android Studio:
- Open the App Actions test tool.
- Optionally enter an invocation name and locale to test in. The default
invocation name and locale are
my test appand
- Click Create Preview. Once your preview is created, the test tool window
will update to display information about BIIs found in your
The invocation name is used when the test tool constructs and simulates a query to the Assistant for your App Actions. You can use any invocation name for the purposes of testing, but deployed App Actions use your Play Store app name. We recommend using the name of your app as your invocation name while testing as well.
The locale you provide must match the language of the 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
To change the invocation name or selected locale for an existing preview, click the Delete Preview button in the test tool. Then, enter the desired invocation name and locale before creating a new preview.
To update an existing preview to match your
actions.xml file, click the
Update Preview button in the test tool. Information about your current
preview can be found in the Test App Action section of the test tool window.
Configuring 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
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
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 described as a mode of transfer, and it
expects values (like
SendMoney) of the enumerated
type. In the test tool, you can provide either of the enumerations as the value
Testing 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:
- Connect your test device.
- In the Select Target Device section, choose the device on which you want to trigger your App Action.
- In the Test App Action section, click the Run 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 the 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, take the following steps:
- Access your Logcat log messages by clicking Logcat in the Android Studio tool window bar.
- Search for logs that include
