The Android Browser Helper library helps developers use Custom Tabs and Trusted Web Activities on top of the AndroidX browser support library. It contains default implementations of many of the common tasks a developer 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.

Adding Android Browser Helper to an Android project

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

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

Information for Google Play's data disclosure requirements

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

Data types collected / shared

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

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

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

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

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

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