Getting started

The first step for a Custom Tabs integration is adding the AndroidX Browser Library to your project. Open the app/build.gradle file and add the browser library to the dependencies section.

dependencies{
...
implementation'androidx.browser:browser:1.5.0'
}

Open a link in a Custom Tab

With the androidx.browser/browser library installed, you can use the CustomTabsIntent.Builder to create a CustomTabsIntent and launch the Custom Tab by calling launchUrl() and passing an Uri:

Stringurl="https://developers.android.com";
CustomTabsIntentintent=newCustomTabsIntent.Builder()
.build();
intent.launchUrl(MainActivity.this,Uri.parse(url));

This will open a fullscreen Custom Tab activity as seen on the following screenshot.

Supporting Android App Links

By default, Custom Tabs support Android App Links. This means, if the YouTube app is installed, launching a CustomTabsIntent with a YouTube video URL will open the YouTube app instead of the browser.

However, passing a CustomTabsSession to a CustomTabIntent will force open the link in a Custom Tab, even if the corresponding native app is installed. If you want to keep the default behavior of opening web links in native apps, you need to additionally follow our guide on how to check if a link can be handled by an installed native app.
