android - Android+jquerymobile+phonegap poor performance compared with iphone / blackberry / nokia

Question

I have an Android Web apps using jquerymobile and phonegap.

I already compress js/html, place my scripts at the bottom of the page, and I am still not satisfied with the performance of my apps, especially when my script is doing DOM manipulation.

The response of the touch event is very slow (>2 sec or event more).

Tested with Android Browser/Android Firefox and the results are still the same.

When I compare the performance to the normal desktop browser / iPhone Safari / BlackBerry Browser / Nokia Browser my apps are responsive.

Specifications:

1. Samsung Galaxy Tab II
2. Android ICS 4.0
3. phonegap 1.8.0
4. jquerymobile 1.1.0

Recap of what I have already tried:

• Get to deviceready faster.
• Minimize / compress JS code using YUI Compressor
• Move script tags to the bottom of the body tag.

Answer 1

试试下面的。

添加：

webview.getSettings().setRenderPriority(RenderPriority.HIGH);
webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

对于清单：

android:hardwareAccelerated="true"

此外，整理和缩小脚本（而不仅仅是缩小）并大量使用 .destroy() 来保持 DOM 修剪。

不幸的是，Android 上的 PhoneGap 速度非常慢。
