The Android Browser Helper library helps developers use Custom Tabs and TrustedWeb Activities on top of the AndroidX browser support library.It contains default implementations of many of the common tasks adeveloper will find themselves requiring, for example:

• Creating a Launcher Activity that simply launches a Trusted Web Activity.
• Code for choosing an appropriate Custom Tabs provider.
• Creating an Activity to launch the browser's site settings for a TWA.

Android Browser helper is available on the Google Maven. To use it, modify your application'sbuild.gradle and add the library as a dependency, as described below:

dependencies {//...    implementation'com.google.androidbrowserhelper:androidbrowserhelper:2.4.0'}

The Android Browser Helper library is intended to allow Android applications to interact withbrowsers on the device. As such, it will share certain types of information with the browser.

Web browsing: URLs handled by the application are shared with the browser when a Custom Tabor a Trusted Web Activity are launched.

URLs are also shared with the browser by certain features like mayLaunchUrl(), so that thebrowser can speed up loading performance of those pages.

When the WebView fallback feature is enabled by the developer, the application may store thenavigation history and browser storage, like cookies on the device.

User location (Optional): The SDK may share location data with the host browser, when thelocation delegation library is used. Users can control sharing of the location using theAndroid permission dialogs and the System settings.

Purchase History (Optional): The SDK may share purchase history data with the host browserwhen the Google Play billing library is used. Only purchases made within the application areshared.

This SDK does not transfer any information over the network. Web browsing information may bestored if the WebView fallback is enabled. The permission to read the location can be managedvia the usual Android settings.
