App Actions Plugin uses now the build.gradle applicationId property,
meaning that is not necessary anymore to change the packageName.

In order to setup the sample only applicationId needs to be change, with
the option to disable Firebase by disabling the flag in app/build.gradle

App Actions Fitness Basic Sample

This is a sample Fitness application that allows displaying workout information as well as starting and stopping a workout. By implementing App Actions, we allow the user to call upon our application to fulfill supported actions from our Fitness vertical Assistant built-in intents (BIIs).

Specifically, this sample supports the following BIIs:

  • START_EXERCISE - opens the sample app and starts an exercise session
  • STOP_EXERCISE - opens the sample app and stops the current exercise session.
  • GET_EXERCISE_OBSERVATION - displays a Slice inside the Assistant with information on a particular exercise statistic

App Actions overview

With App Actions, your app can be triggered by users through the Google Assistant on Android devices. To support App Actions, your app must implement Android deep links to your app content, allowing the Android system to invoke a specific Activity when the App Action is triggered.

Users invoke App Actions through phrases associated with built-in intents (BIIs). The Assistant handles these BIIs so that your app receives the user's input without you needing to create a conversational Action, or having to deal with natural language processing by yourself.

You map the BIIs that are relevant to your app and their parameters to your Android deep links within a file named actions.xml. For more details, check out our developer documentation for App Actions.

Importing this sample

Check out or download the project to your preferred location. You can import the project using the Android Studio with the following steps:

  1. Select "Open an existing Android Studio project" from the initial screen, or File --> Open
  2. Find the directory where you saved the sample.
  3. Select the build.gradle file
  4. Follow the instructions presented by the IDE.

Requirements

Since the App Actions feature is in Developer Preview, to run the sample or use App Actions in any other app, a few extra steps are required.

The actions.xml file that defines the supported actions for your app (or in this case the sample), needs to be uploaded into the Assistant. This is done via the App Actions Test Tool Android Studio plugin (the installation instructions are listed below).

For security and verification reasons, when uploading the actions.xml file with the plugin, the account used, must have ownership of the application ID.

Login in Android Studio with your account and use one of your published applications IDs in Google Play Console. If you don't have any, you can upload one in draft mode (it does not have to be published).

Change the applicationId in app/build.gradle

android {
    defaultConfig {
        applicationId "com.devrel.android.fitactions" // Use one of your published applications IDs
    }
}

Also, Google Assistant must be installed on the test/target device with the same account used in Android Studio.

Finally, the sample shows how to use the Firebase App Indexing to track the success or failure of the actions received. Re-use or create an app in Firebase following these steps and make sure the google-service.json is available in the app module.

Note: as alternative, if you want to skip this step, you could disable Firebase by setting firebaseEnabled flag to false in app/build.gradle

How to run

Once the requirements above are satisfied, you are ready to run the sample.

  1. Run the code and install the sample in the device (Run app)
  2. Open the App Actions plugin (Tools -> App Actions Test Tool)
  3. Define an invocation name that will be used to trigger the actions (i.e My Fit App)
  4. Press 'Create Preview'. If the setup was successful, you will see a panel like this

app-actions-plugin

  1. Select the action and click run.

The Assistant should show up and run the selected action.

Once you run this once, you can then try using voice or written commands directly in the Assistant.

Installing the App Actions plugin

  1. If you are using Linux or Windows, click on File → Settings. For MacOS, click on Android Studio → Preferences
  2. Select the Plugins section
  3. Search for "App Actions Test Tool"
  4. Install and restart your IDE

Troubleshooting

Make sure that you follow these steps:

  • Own a Google account
  • Application ID used is published in Google Play console (at least as draft)
  • Google Account has access to the application in Google Play Console
  • Logged in Android Studio with the Google Account
  • Logged in with the same account in the testing device
  • Actions.xml file is defined in the Application project
  • Upload preview using App Actions plugin
  • App is available in the device.

If the plugin is not able to load the preview of the action, make sure that:

  • The account used in Android Studio is the same as the one in the device
  • The account used must own or have access in Play console to the applicationId defined in build.gradle
  • Android Studio has access to an internet connection.
  • If you modified the actions.xml, make sure the right syntax is used.

If the action is not running in the device or Assistant is not reacting, make sure that:

  • The plugin loaded the actions preview at least one time.
  • The account in the device is the same as the one in Android Studio.
  • The device has access to an internet connection.
  • You are using the latest version of the Assistant or Google app.

App Actions is in Developer Preview, you can't upload an application to Google Play that defines actions in the AndroidManifest.xml. Remove the metadata tag to upload it
