how to optimize renderspeed in android webview
There are a few things you can try:
Turn on hardware acceleration by adding
android:hardwareAccelerated="true"to the application or activity tag in the Android manifest file. More info here: http://developer.android.com/guide/topics/graphics/hardware-accel.htmlModify the RenderPriority of the webview - http://developer.android.com/reference/android/webkit/WebSettings.RenderPriority.html
Optimize your javaScript and CSS to minimize the number of reflows, memory used, and DOM size - http://www.html5rocks.com/en/mobile/mobifying.html#toc-optimizations
Personally, I found that keeping the DOM as small as possible, and enabling hardware acceleration made all of the difference between an unusable app, and a fairly smooth app.
