How to Implement Open URL Intent in Android Studio: A Step-by-Step Guide

In this article, we will explore the concept of open URL intent in Android Studio and provide a step-by-step guide on how to implement it in your app.

Open URL Intent: What is it?

Open URL intent is an intent that allows your app to handle specific types of URLs. When a user clicks on a link or requests a web URI, the Android system tries to launch the app that can handle the URI. This feature is particularly useful when you want to open your app automatically whenever a user clicks on a link.

Adding Intent Filters

To implement open URL intent in your app, you need to add intent filters to your app's AndroidManifest.xml file. An intent filter specifies the types of intents that an app can handle. Here are the attributes and elements you need to include:

* `android.intent.action.VIEW`: This is the action that will be performed when a user clicks on a link.

* `data`: This specifies the data that the intent will handle.

* `scheme`: This specifies the scheme of the URL (e.g., http, https).

* `host`: This specifies the host of the URL.

Here's an example of how to add intent filters in your AndroidManifest.xml file:

```xml

```

In this example, the intent filter specifies that your app can handle URLs with the scheme `http` and host `example.com`.

Passing Data from URL to App

When a user clicks on a link or requests a web URI, you can pass data from the URL to your app using query parameters. Query parameters are key-value pairs that are appended to the URL.

For example, if you want to pass a parameter called `id` with value `123`, you would add it to the URL like this:

```url

http://example.com?id=123

```

In your app, you can retrieve query parameters using the `Intent` class. Here's an example of how to do it:

```java

Intent intent = getIntent();

String id = intent.getStringExtra('id');

```

In this article, we have learned how to implement open URL intent in Android Studio by adding intent filters and passing data from URLs to our app. With these features, you can automatically launch your app whenever a user clicks on a link or requests a web URI.
