Sebastien Lorber created CB-9346: ------------------------------------ Summary: Cordova index.html doctype has huge Android performance impact Key: CB-9346 URL: https://issues.apache.org/jira/browse/CB-9346 Project: Apache Cordova Issue Type: Bug Components: Android Affects Versions: 4.0.0 Environment: Nexus4 (4.4.3), SKD22, minTarget=16, target=22, Ubuntu 12.04, cordova-cli=5.1.1 Reporter: Sebastien Lorber
Hi, This is another case were the exact same app, running on the same device, is slower in webview than in mobile browser. In my company we have a mobile website, that runs fine in mobile web browser. We started to port it to a cordova/phonegap application so that is runs in webview and is available in Android/iOS stores. So I'm trying to run for some days the app in a Cordova shell. It works, but is really is a lot slower than using the mobile browser. As far as I know, I run 4.4.3 version of Android so it's supposed to use new Chromium-based webviews that are faster than former android webviews. According to readings on the internet, I tried many things, including changing the hardwareAccelerated true/false, updating the min/target SDK, or even using the Crosswalk plugin. None of these had a significant effect. Also I noticed some little CSS bugs in the Cordova version compared to the mobile version, like a scrollable container that did not have the appropriate height... I finally figured out that we were using `<!DOCTYPE html>` on the Cordova index.html while we were not in the html served for mobile browsers. So I tried to remove the <!DOCTYPE html> from the index.html of Cordova, primarily to fix the CSS bug (http://stackoverflow.com/questions/1966300/height-100-is-not-working-in-html-when-using-doctype-how-i-can-fix-this) After removing the doctype, it solved the CSS bug, but also solved the performance issue! Can someone explain why this doctype has any impact on performances? Is it a Cordova bug? I can notice that the doctype is included in all Phonegap examples I've seen so far. Is it really required? And what can be the impact of removing this doctype? -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@cordova.apache.org For additional commands, e-mail: issues-h...@cordova.apache.org
