Set up Android App Links

Android App Links are HTTP URLs that send users to a specific in-app location or a relevant web page. With an Android App Link, you can set your app as the default app for a certain type of link. App Links improve the user experience by saving time users spend on getting to content.

Before you begin

Here's what you need to know before getting started.

Requirements

• A single or multi-platform mobile app.
• Admin permissions in Adjust.
• A branded domain set up in your app.
• Support for URI schemes in the Adjust SDK.
• Android App Links set up in the Adjust SDK.

Retrieve SHA-256 certificate fingerprints

A certificate fingerprint is a cryptographic hash of the public information held within a certificate. Certificate fingerprints are public information, and are designed to be used by third-parties for app verification. Adjust never requests private app signing keys. For more information about certificate fingerprints, see Google’s documentation.

The method you use to retrieve your certificate fingerprint depends on your build destination. Use the information in the table below to identify the most suitable approach for your scenario:

From Google Play Console

Follow these steps to retrieve the SHA-256 certificate fingerprint.

1. In Google Play Console, go to your app.
2. Under Release, go to Setup > App signing.
3. Under App signing key certificate, copy the SHA-256 certificate fingerprint.
4. Under Upload key certificate, copy the SHA-256 certificate fingerprint.

Under App signing key certificate, copy the SHA-256 certificate fingerprint.

Under Upload key certificate, copy the SHA-256 certificate fingerprint.

From Google Play Console - Internal App Sharing

If you use Google Play Internal App Sharing, follow these steps to retrieve the SHA-256 certificate fingerprint.

1. In Google Play Console, go to your app.
2. Under Release, go to Setup > Internal app sharing.
3. Under Internal test certificate, copy the SHA-256 certificate fingerprint.

From Huawei AppGallery App Signing

If you use Huawei AppGallery App Signing, follow these steps to retrieve the SHA-256 certificate fingerprint.

Note:

If you don’t use Huawei App Signing, follow the instructions for retrieving your certificate fingerprint from a keystore.

1. In AppGallery Connect, select My Apps.
2. Select your app.
3. Under Services, go to App Signing.
4. Under App signature certificate, copy the SHA-256 certificate fingerprint.
5. Under Upload Certificate, copy the SHA-256 certificate fingerprint.

From a keystore

If you use your own keystore, or if Android Studio generated a keystore for you, follow these steps to retrieve the SHA-256 certificate fingerprint.

1. Find the keystore file (.jks) you used to sign the app.
2. Run the following command to list your keys. Replace the parts in angle brackets with your information.

keytool -list -v -keystore <path/to/keystore.jks> -alias <your_key_alias>

1. When prompted, enter the password you defined when you generated the keystore.

The final output looks like this:

1. Retrieve the value of the SHA-256 certificate fingerprint from the output.

Set up Android App Links in AppView

Now, follow these steps in Adjust to enable Android App Links:

1. Find your app in AppView.
2. Go to the Platforms tab.
3. Under Android, turn on the Enable deep links for Android App Links toggle.
4. Enter your SHA-256 certificate fingerprints. This is what you had retrieved in the previous step.
5. Enter the App scheme. This is what you had defined while adding support for URI schemes in your app.
6. Select Save.
