Android WebView renderer extensions

This directory contains APIs exclusive to the Android WebView. Feature authors cannot begin implementing features under this directory until they follow the engagement protocol below.

Scope of this directory

This directory is used for

• Web facing APIs or extensions to web facing APIs that will only be available to Android WebView.

This directory is not used for

• Android WebView APIs that are Android facing.
• Web APIs going through standardisation.

Engagement protocol

Before engagement

When the regular process for launching features has been found to be inconclusive, and a reason exists to explore whether an Android WebView extension would be appropriate, the feature authors:

• Should document requirements, and why this would benefit WebView users on Android,
• Should document explicitly why this functionality cannot be generalised to the web platform as a whole,
• Should not have committed to the Android WebView extension route,
• Should not have sent out an Android WebView extension implementation out for review.

Engagement

Before a decision may be made, the following process should be followed:

1. A review request is sent out to blink-api-owners-discuss@chromium.org
   1. At this stage, feature authors are allowed to begin opening CLs for the feature
2. A Blink API owner must LGTM the feature on that mailing list before it can land within Blink
   1. Feature authors may then land the feature under this directory
3. If any significant changes to the feature happen after step 2, the feature author should notify blink-api-owners-discuss@chromium.org, and if a concern is raised, go back to step 2.

Feature authors may explore supporting the feature outside of Blink if no Blink API owner LGTMs the feature.
