Brotli Support

[josemgmz]

Hello,

I've been trying to get websites to improve download times and I've been trying to use brotli compression.

As I understand

for iOS: from version 11.0 - 15.1, support for brotli is already provided.

for android webview since chromium 98 version.

However, I have been able to read that this support is only for google chorome for the android Webview is an experimental flag in the WebView settings.

Can this flag be activated for all users using my version of webview?

A greeting and thank you very much for the help.

You can launch the dev ui with adb,

https://chromium.googlesource.com/chromium/src/+/HEAD/android_webview/docs/developer-ui.md#launch-via-adb

or by intent (the following is a diff for the sample app):

diff --git a/sample/Assets/Scripts/SampleWebView.cs b/sample/Assets/Scripts/SampleWebView.cs

+        if (GUI.Button(new Rect(x, 10, 80, 80), "DEV")) {
+            var player = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
+            var activity = player.GetStatic<AndroidJavaObject>("currentActivity");
+            var intent = new AndroidJavaObject("android.content.Intent");
+            intent.Call<AndroidJavaObject>("setAction", "com.android.webview.SHOW_DEV_UI");
+            activity.Call("startActivity", intent);
+        }
+        x += 90;
     }
 }

However, it seems to be difficult to enable the flag directly from the app.
