OAuthUserSignInActivity

An activity that is responsible for launching a CustomTabs activity and to receive and process the redirect intent as a result of a user completing the CustomTabs prompt.

This activity must be registered in your application's manifest. There are two ways to configure the manifest entry for OAuthUserSignInActivity:

The most common use case is that completing an OAuth challenge by signing in using the CustomTabs browser should redirect back to this activity immediately and allow the OAuthAuthenticator to immediately handle the completion of the challenge. In this case, the activity should be declared in the manifest using launchMode="singleTop" and an intent-filter should be specified:

<activity
android:name="com.arcgismaps.toolkit.authentication.OAuthUserSignInActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:exported="true"
android:launchMode="singleTop" >
  <intent-filter>
    <action android:name="android.intent.action.VIEW" />

    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />

    <data
      android:host="auth"
      android:scheme="my-ags-app" />
    </intent-filter>
</activity>

Should your app require that the redirect intent from the browser is handled by another activity, then you should remove the intent filter from the OAuthUserSignInActivity and put it in the activity that you want the browser to redirect to. Depending on your app's configuration, you may need to change the launch mode to singleInstance, but be aware that this will expose the browser as a separate task in the recent tasks list.

<activity
android:name="com.arcgismaps.toolkit.authentication.OAuthUserSignInActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:exported="true"
android:launchMode="singleInstance" >
</activity>

Then, in the activity that receives the intent as a result of completing the CustomTab, you can pass that on to the OAuthUserSignInActivity by copying the intent.data and starting the activity directly:

val newIntent = Intent(this, OAuthUserSignInActivity::class.java).apply {
  data = uri
}
startActivity(newIntent)
