WebID Android Feature

This folder contains the Android UI implementation for the WebID feature.

[TOC]

Use case

This component displays a set of accounts. The user selects one which is then used to complete authentication via WebID mediation based approach.

Folder Structure

java/

The root folder contains the public interface of this component and data that is used to fill it with content, e.g. Accounts.

Add chrome/browser/ui/android/webid/android:public_java as dependency to use the interface and classes defined here.

java/internal/

Contains the actual implementation. Don't try to use any class defined here outside of this package. If you need access to any method, consider making it part of the public interface as defined in AccountSelectionComponent

This folder contains a separate README that explains in detail how the architecture looks like and how to extend the component further.

junit/

Contains Robolectric tests that test the delegate of the component. These tests run without emulator which means that they are incredibly fast but cannot instantiate or verify Android Views. The public build and run target is chrome_junit_tests. Run them with:

bash

./out/<OutDirectory>/bin/run_chrome_junit_tests -f*AccountSelection*

javatests/

Contains View and Integration tests. These instrumented unit tests need an emulator or a physical device which means that they run slowly but can test rendered Views. Native Calls should be used very sparingly to ensure access to all methods in the Dex path list. The public build and run target is chrome_public_test_apk. Run them with:

bash

./out/<OutDirectory>/bin/run_chrome_public_test_apk -f *AccountSelection*

Example usage

java


// Currently, you need access to internal/ to instantiate the component:
AccountSelectionComponent component = new AccountSelectionCoordinator(/*...*/);

component.initialize(activity, activity.getBottomSheetController(), () -> {
  // Things to do when the component is dismissed.
}));

List<Account> accounts; // Add accounts to show!
component.showAccounts("www.displayed-url.example", accounts, (account) -> {
  // The |account| that was clicked should be used to fill something now.
});
