Autofill Services provide Autofill data for all apps. In Chromium, a built-in service provides Autofill data across all platforms. Users can switch to using the device-wide Autofill Service. This example implementation is used to test Chromium with a primitive implementation.
It provides an AutofillService which provides static data for each field by echoing the type of field and a number. It allows filling simple forms. This Service supports inline suggestions.
The main activity explains how to set the service in settings and provides additional information.
It should help to understand how an app can interact with Chrome using intents and ContentProviders.
These instruction assume that you have already built Chromium for Android. If not, instructions for building Chromium for Android are here. Details below assume that the build is setup in $CHROMIUM_OUTPUT_DIR.
To build the test app and the AutofillService, execute:
$ autoninja -C $CHROMIUM_OUTPUT_DIR inline_autofill_service_example_apk
To install the test app and the AutofillService, execute:
# Install the example $ $CHROMIUM_OUTPUT_DIR/bin/inline_autofill_service_example_apk install
The Autofill Service has to be enabled in Android settings. Select it as Autofill provider. Additionally, enable in Chromium settings > Autofill Services that the external service may be used. Restart Chromium.
The test app appears in the app drawer and can be started from there.
