This guide presents a step-by-step workflow for integrating the Engage SDK
into your app.

## Shared resources

The following resources are available to assist with integration:

### Verification app

A [verification app](https://developer.android.com/guide/playcore/engage/workflow#lightbox-trigger) used
to verify content publishing in the UI.

### Content publishing guidelines

[Documentation](https://developer.android.com/guide/playcore/engage/publish) providing guidelines on how to effectively publish content
using the APIs.
| **Note:** The resources were last updated on December 15, 2025. Make sure to download the latest version.

## Step 1: Develop with the SDK debug mode

Add the Engage SDK in the `build.gradle` file and follow the appropriate
vertical-specific integration guide to complete your integration.  

    dependencies {
        // Make sure you also include the repository in your project's
        // build.gradle file.
        implementation 'com.google.android.engage:engage-core:1.5.11'
    }

## Step 2: Install the verification app

The verification app is an Android application that you can use to
verify that the integration is working. The app includes capabilities to help
developers verify data and broadcast intents.

## Step 3: Verify that data is visible in the verification app

The verification app should display each cluster as a separate row.

- Enter the name of the developer package that is publishing the data.

![](https://developer.android.com/static/images/guide/playcore/engage/workflow-data-1.png) **Figure 1**: Enter package name

- Verify that all entities in the cluster are published.

![](https://developer.android.com/static/images/guide/playcore/engage/workflow-data-2.png) **Figure 2**: Confirm all entities in the cluster are published

- Verify that all fields in the entity are published. For each item in the row, you can click the poster image to verify the intent.

![](https://developer.android.com/static/images/guide/playcore/engage/workflow-data-3.png) **Figure 3**: Verify entity fields and poster image

- Review the summaries for the app, cluster, and entity levels that indicate the count of validation errors. Review the validation error messages that appear in red beneath each relevant field. Validation errors occur when required fields are missing or have incorrect values.

## Step 4: Verify the broadcast intent flow

| **Note:** The verification app doesn't support testing broadcast intent with permission. You must remove permissions while testing and add them back before proceeding to [Step 6](https://developer.android.com/guide/playcore/engage/workflow#switch-to-prod).

To verify the broadcast intent, click the button at the top of the UI to
trigger the logic for sending broadcasts.

Once steps 1 through 4 are complete, you have finished testing the integration
on your end.

## Step 5: Self-certify your integration

Before our review, you must complete a self-certification. This is a
critical step to verify your integration is ready and to help streamline the
review process.

- Enter the package name and click the "Start self-certification" button on the
  verification app home page.

  ![](https://developer.android.com/static/images/guide/playcore/engage/workflow-data-6.png) **Figure 7**: Starting self-certification

  <br />

- On the next page, select your vertical from the drop-down list. This displays the list of tests for the vertical:

![](https://developer.android.com/static/images/guide/playcore/engage/workflow-data-7.png) **Figure 8**: Self-certification in progress

- Use the Verify app to test your integration against each test case rendered on Verify app.

  - The **progress bar** indicates the number of tests executed so far.
  - Click the **View Details** button to view the steps to perform the test and the expected behavior, manual verifications required.
  - The middle section of the self-certification page displays the published clusters.
  - Click the **Record test result** button to record the test result. Provide justification if you mark a test as failed or skipped.
  - Use **Back** and **Next** buttons to navigate to the previous and next tests respectively.
  - Click **Quit Testing** button or close the Verify app at any time to exit testing. The current testing session is saved automatically and can be resumed or re-run at any time (even if the Verify app is closed or if the device is restarted). When you enter the same package name and select the same vertical at the start of self-certification, the Verify app shows a prompt asking if you want to resume with the current testing session.
  - Click **Download session** button to download the current testing session as a CSV file. This CSV file can be shared and this session can be loaded into Verify app using the "Load shared session" button on the Verify app home page. Note that only the test cases and test results are saved in the downloaded session.
- Once you have completed testing, click the **Complete Testing** button to
  generate a downloadable summary of the self-certification testing.

![](https://developer.android.com/static/images/guide/playcore/engage/workflow-data-8.png) **Figure 9**: Self-certification completion

After you complete steps 1 through 5, you have finished your integration
testing.

## Step 6: Re-check: Switch to the SDK prod version

After debugging is complete, you must update the metadata in your manifest file:  

    <application>
      ...
      <meta-data
            android:name="com.google.android.engage.service.ENV"
            android:value="PRODUCTION"></meta-data>
    </application>

| **Warning:** Make sure the metadata is updated before releasing the app to the **Play Store**.

## Step 7: Send Google the release-ready APK

Send a copy of your release-ready APK file as an email attachment to
[`engage-developers@google.com`](mailto:engage-developers@google.com). Also attach the completed
self-certification summary generated by the Verify app. Google will verify that
the integration is working as intended. After Google verifies the integration,
you can submit the app to production for release.
| **Warning:** Make sure the package name of the APK matches the package name released to the **Play Store**.

## Step 8: Publish the APK to the Play Store

Once you have received approvals, publish the APK to the Play Store. After
you publish the APK, send an email to [`engage-developers@google.com`](mailto:engage-developers@google.com)
with the released version number. Google will respond with next steps.
