Aim: Assist Android builders with a fast and easy Android App Hyperlinks implementation instance
In the event you’re already accustomed to the technical particulars behind the design, configuration, implementation, and verification of Android App Hyperlinks, and also you wish to get began in your personal app immediately, then this weblog submit is for you. In case you are excited by studying extra about these particulars, we’ve a codelab that covers them.
Here’s what you will want to efficiently implement an Android App Hyperlink:
- Newest model of Android Studio
- A deployed area with public entry
- (Non-obligatory) Google Play developer account setup
Listed below are the steps to assist an Android App Hyperlink. These steps create a primary software that shows the Intent data from an App Hyperlink.
1.1 In Android Studio create a brand new venture and choose “Empty Compose Exercise”.
1.2 Ensure the appliance runs as anticipated earlier than you begin including code. You must see an empty software with a “Hi there Android!” message:
2.1 Embody the intent filter in AndroidManifest.xml so the MainActivity will open Android App Hyperlinks.
2.2 Ensure to replace area instance.com and path: /example-path. These ought to mirror your web site implementation construction.
3.1 With a view to parse the Android App Hyperlink knowledge obtained it’s important to add the next logic into the primary exercise (MainActivity.kt) of your app:
3.2 In the event you run this logic you will notice the next textual content strings: One shows the Hi there Android! message, the second shows the motion for the intent that was known as, and the third one shows the URL for the intent that was known as.
Earlier than importing the assetlinks.json file, which is a part of the Digital Asset Hyperlinks (DAL) protocol, you’ll want to get the appliance certificates fingerprint. On this case since we haven’t launched the app to the Google Play Retailer we will use the debug certificates fingerprint. If you wish to add the app to Google Play, you should embody your releasing signing key. This web page explains the best way to do it.
4.1 To acquire the debug/launch certificates fingerprint, run the next command below the “Run Something” menu in Android Studio:
Necessary Be aware: The debug certificates fingerprint is insecure by nature and may solely be used for debugging functions. The Google Play Retailer will reject any app downloaded with this certificates.
4.2 From the output of this command, copy the fingerprint below the SHA-256: part:
Now we have a separate weblog submit detailing this course of. Right here we current the brief model.
5.1 Below your area within the following location: <instance.com>/.well-known/ embody a file known as assetlinks.json with the next format:
The ensuing hyperlink ought to look one thing like this:
https://instance.com/.well-known/assetlinks.json
You also needs to be sure the file is publicly accessible.
5.2 Replace the package_name and sha256_cert_fingerprints with your personal package deal title and fingerprint that you simply obtained within the earlier step.
You must now be able to launch your app, launch an intent, and confirm that your app receives it as an Android App Hyperlink.
6.1 Run your app and ensure you see the primary exercise seem.
6.2 Run the next adb command:
6.3 Confirm that the Android App Hyperlink knowledge is obtained on the primary exercise display screen.
In the event you don’t see the Android App Hyperlink knowledge obtained, you might need to reinitialize the Android App Hyperlink verification course of. Listed below are instructions to realize this:
7.1 Reset Android App Hyperlinks state.
7.2 Run the verification course of. It would take as much as 5 minutes earlier than the verification companies get the updates.
7.3 Receive the verification outcomes.
This command outputs the results of the verification course of, and you need to see output just like this:
Ensure the standing of your area is verified. If not, please begin the verification course of once more.
Congratulations! You efficiently applied your first Android App Hyperlink. In case you are excited by a deeper take a look at this course of, please confer with this codelab.
