      targetSdkVersion = 28
      // Remove 'supportLibVersion' property and put specific versions for AndroidX libraries
      androidXBrowser = "1.0.0"
      // Put here other AndroidX dependencies
    }

Demo

import { Utils, Dialogs } from '@nativescript/core';
import { InAppBrowser } from 'nativescript-inappbrowser';

...
  openLink = async () => {

          animated: true,
          modalPresentationStyle: 'fullScreen',
          modalTransitionStyle: 'coverVertical',

      }
    }
    catch(error) {
      Dialogs.alert({

        message: error.message,
        okButtonText: 'Ok'
      });
    }
  }

Android Optimizations

On Android, you can warmup the in app browser client to make it launch siginificantly faster. To do so, add the following to your Custom Android Activity.

import { InAppBrowser } from "nativescript-inappbrowser";
@NativeClass()
@JavaProxy("org.nativescript.demo.MainActivity")
export class Activity extends androidx.appcompat.app.AppCompatActivity {
  public onStart(): void {
    // InAppBrowser initialization for CustomTabsServiceConnection
    InAppBrowser.onStart();
  }
}

You can further optimize performance and pre-render pages by providing the urls that the user is likely to open.

constructor() {
  super();
  // Do not call this every time the component render
  InAppBrowser.mayLaunchUrl(this._url, [
    "https://twitter.com/NativeScript",
    "https://github.com/NativeScript/NativeScript",
    "https://openjsf.org"
  ]);
}

Authentication Flow using Deep Linking

In order to redirect back to your application from a web browser, you must specify a unique URI to your app. To do this, define your app scheme and replace my-scheme and my-host with your info.

• Enable deep linking (Android) - AndroidManifest.xml

<activity
  ...
  android:launchMode="singleTask">
  <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:scheme="my-scheme" android:host="my-host" android:pathPrefix="" />
  </intent-filter>
</activity>

• Enable deep linking (iOS) - Info.plist

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleTypeRole</key>
    <string>Editor</string>
    <key>CFBundleURLName</key>
    <string>my-scheme</string>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>my-scheme</string>
    </array>
  </dict>
</array>

• utilities.ts

export const getDeepLink = (path = "") => {
  const scheme = 'my-scheme';
  const prefix = global.isAndroid ? `${scheme}://my-host/` : `${scheme}://`;
  return prefix + path;
}

• home-page.ts

import { Utils, Dialogs } from '@nativescript/core';
import { InAppBrowser } from 'nativescript-inappbrowser';
import { getDeepLink } from './utilities';
...
  async onLogin() {
    const deepLink = getDeepLink('callback')
    const url = `https://my-auth-login-page.com?redirect_uri=${deepLink}`
    try {
      if (await InAppBrowser.isAvailable()) {
        InAppBrowser.openAuth(url, deepLink, {
          // iOS Properties
          ephemeralWebSession: false,
          // Android Properties
          showTitle: false,
          enableUrlBarHiding: true,
          enableDefaultShare: false
        }).then((response) => {
          if (
            response.type === 'success' &&
            response.url
          ) {
            Utils.openUrl(response.url)
          }
        })
      } else Utils.openUrl(url)
    } catch {
      Utils.openUrl(url)
    }
  }
...

StatusBar

The StatusBar will keep the last one provided in your app. So if the StatusBar is dark-content before you open the browser this will keep it.

Authentication

Using in-app browser tabs (like SFAuthenticationSession/ASWebAuthenticationSession and Android Custom Tabs) where available. Embedded user-agents, known as web-views (like UIWebView and WKWebView), are explicitly not supported due to the usability and security reasons documented in Section 8.12 of RFC 8252.
