is the hardware rendering for android webview shell

[Xiaofeng]

Hi

I see this topic: Is it possible to enable hardware rendering for android webview shell and some information here

Build WebView shell

.....The WebView shell is a view with a URL bar at the top (see code) and is independent of the WebView implementation in the Android system (the WebView shell is essentially a standalone unbundled app). As drawback, the shell runs in software rendering mode only.

However, from the git log in AwTestContainerView.java:

commit 386f9301889efde34b202a4600496b1e10aa06c8

Author: sievers <sie...@chromium.org>

    android: Use hw acceleration in android_webview_shell

    

    This creates a (GL)SurfaceView overlay on top of the shell

    container view which runs its own thread for rendering.

    It calls into the native draw functor through a small

    dynamic library (drawgl.so).

If the Android WebView Shell has been changed to HW rendering mode, the build guide  here also need to be updated to avoid the confusion.

The webview instrumentation test shell does run in hardware mode now, after that CL from sievers you found. It uses a SurfaceView to fake the private android rendering APIs, so two caveats:

* It's different from how webview renderings in production, and is only used in tests to exercise hardware rendering code path.

* Only the first webview created in the shell is hardware accelerated. This really only applies to tests, since there is no UI to create more than one webview in the shell.

I've updated the wiki page to say "non-production" instead of "software".

Build android_webview_apk from chrome. Then start looking at AwContents the majority of methods from webview.

Also a word of warning that there are few legitimate reasons to build a custom webview into your app.

Thank you  for your reply,

but what do you mean to say "there are few legitimate reasons"?

And could you tell me some more steps what I can do from android_webview_shell?

Webview is part of the system. Apps that want to bundle its own webview or web engine generally want more control/consistency, but they ignore other down sides like security, fragmentation, memory/disk usage, etc.

 

And could you tell me some more steps what I can do from android_webview_shell?

Follow those instructions, but build android_webview_apk instead of chrome_public_apk
