If you use Android Native to develop your application, the first thing you need is to install this dependency in the build.gradle file.

Java
Copiar
dependencies {
    ...
    implementation "androidx.browser:browser:1.4.0"
}

The next step is to implement the Custom Tab. To do this, you just need to instantiate them. Below we share an example of a simple Custom Tab.

The following code can be placed when opening an activity or performing an action on it, where the url value is equal to the init url of our checkout.

String url = "YOUR-checkout_url";
CustomTabsIntent intent = new CustomTabsIntent.Builder()
       .build();
intent.launchUrl(MainActivity.this, Uri.parse(url));

val url = "YOUR-checkout_url"
    val intent = CustomTabsIntent.Builder()
        .build()
    intent.launchUrl(this@MainActivity, Uri.parse(url))

Deep Links are a powerful way to allow direct navigation to specific screens or sections of a mobile application.

From our checkout, you can configure Deep Links to return to your application, either by clicking a "Back" link or automatically after completing a successful payment flow, redirecting you back to your application.

For this, we must configure the return URLs in the config.online object when creating the order (success_url, failure_url, pending_url and auto_return), as needed.

To learn more, you can visit the documentation on Return URLs.

To set up a native Deep Link on Android, go to the Android /app/src/main/AndroidManifest.xml file and declare which activity will be available as a Deep Link. Below we share an example of what an activity with Deep Link looks like.

AndroidManifest.xml
Copiar
<activity
   android:name=".Congrats"
   android:exported="true"
   android:label="@string/deeplink"
   android:theme="@style/Theme.MyApplication.NoActionBar" >

   <intent-filter>
       <action android:name="android.intent.action.VIEW" />
       <category android:name="android.intent.category.DEFAULT" />
       <category android:name="android.intent.category.BROWSABLE" />
       <!-- Accepts URIs that begin with "yourapp://congrats" -->
       <data android:scheme="yourapp"
           android:host="congrats" />

   </intent-filter>
</activity>

In the intent values, you must define the activity as browsable by other applications. With the scheme and host values, you can set the application's Deep Link to a specific activity.

Remember that this Deep Link will be used on all return URLs of your payment order. In the cycles of the activity that was exposed (e.g. onCreate, onResume) you will be able to enter your business logic after payment.
