Android 15 May Pin WebView Component to Memory for Faster Page Loads
-
Android 15 may pin part of the Android System WebView component to memory to help it load webpages faster when apps use it.
-
Many apps rely on Android System WebView to display web content without opening a separate browser.
-
WebView is based on the Chromium open source project, like Chrome, and shares some code with Chrome via the trichrome library.
-
Android 15 Developer Preview 1 pins 20MB of the 161MB trichrome library to memory when the "pinWebView" flag is enabled.
-
This change may provide a small speed boost to WebView start up time, especially on lower RAM devices, but it's not guaranteed to remain in future Android 15 builds.
