How to use App Linking to achieve seamless jump and QR code pull

Through the Huawei HMS Core App Linking service, the following functions can be implemented: Set up App Linking: Configure the associated domain, application, and key in the Huawei Developer Alliance. Seamless jump: Integrate HMS Core Kit in your app and handle the applink: URI intent in MainActivity for jumps. QR code pull up: generate a QR code containing the applink: URI, scan and start the application through the AppLink.handleAppLink() method.

How to use App Linking to achieve seamless jump and QR code pull

App Linking is a service provided by Huawei HMS Core, which enables seamless jumps and QR code pulls up between different applications and devices. The following are the specific implementation methods:

Set up App Linking

1. Apply for a signature key: Go to the Huawei Developer Alliance website to apply for a signature key.
2. Configure App Linking: Configure App Linking in the Huawei Developer Alliance console, including setting up the associated domain, associated application, and signature key.

Develop applications

Seamless jump:

1. Integrated HMS Core Kit: Integrate HMS Core Kit in your application (version 5.4.0 and above).
2. Processing intention: Process the applink: URI intent in MainActivity, parse the data in the link and perform corresponding redirects.

QR code to pull up:

1. Generate QR code: Use HMS Core Kit to generate a QR code containing the applink: URI.
2. Scan the QR code: After scanning the QR code, parse the scan result into an applink: URI.
3. To set up the application: Use the AppLink.handleAppLink() method to set up the corresponding application and pass the parsed data.

Sample code:

Seamless jump:

 <code class="java">Intent intent = getIntent(); if (intent.getData() != null) { String url = intent.getData().toString(); // 解析链接数据并进行跳转}</code>

QR code to pull up:

 <code class="java">AppLink appLink = AppLink.fromUri(scanResult.getRawValue()); if (appLink != null) { Intent appLinkIntent = appLink.getAppLinkIntent(); // 调起应用并传递数据startActivityForResult(appLinkIntent, 0); }</code>

Notes:

• The associated domain must be a valid domain name accessed by the application.
• The signature key must be the same as the application signature key submitted to the app store.
• The target application must correctly handle the application: URI intention and QR code to pull up the processing logic.

By leveraging App Linking, developers can provide users with seamless jumps and QR code pull-up experiences, thereby improving application usability and user satisfaction.
