Question

拜托，我想向Appcelerator / Titanium社区寻求帮助。我的应用程序在Android上使用Titanium SDK的5.X，6.0.0和6.0.1版本运行得非常好。出于某种原因，从版本6.0.2开始，包括6.0.3,6.0.4和6.1.X，它非常慢。我升级了Android SDK版本，包括build-tools和Node.js，但没有任何改进。另外，在iOS上一切都很好。我知道这是一个非常普遍的问题，但有人在Android上使用这些版本的Titanium SDK遇到性能问题？非常感谢提前。

以下是有关我的环境的信息：

Operating System
  Name                        = Mac OS X
  Version                     = 10.11.6
  Architecture                = 64bit
  # CPUs                      = 8
  Memory                      = 8589934592

Node.js
  Node.js Version             = 4.5.0
  npm Version                 = 2.15.9

Titanium CLI
  CLI Version                 = 5.0.14

Titanium SDK
  SDK Version                 = 6.0.2.GA
  SDK Path                    = /Users/luna/Library/Application Support/Titanium/mobilesdk/osx/6.0.2.GA
  Target Platform             = android

经过几个小时的浪费，我发现问题与网页浏览有关（仅适用于Android）。以下是解释我问题的单一代码：

//
var win = Titanium.UI.createWindow({
    backgroundColor: 'white'
});

var htmlContent = '<html><head><meta http-equiv=Content-Type content="text/html; charset=utf-8">';
htmlContent += '<meta name="viewport" content="width=device-width, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no" />';
htmlContent += '</head><body This text is intended as a test for the webview usage examples:<br>';
htmlContent += 'Morbi a metus. Phasellus enim erat, vestibulum vel, aliquam a, posuere eu, velit. <br>Nullam sapien sem, ornare ac, nonummy non, lobortis a, enim. Nunc tincidunt ante vitae massa. <br>Duis ante orci, molestie vitae, vehicula venenatis, tincidunt ac, pede. <br>Nulla accumsan, elit sit amet varius semper, nulla mauris mollis quam, tempor suscipit diam nulla vel leo. <br>Etiam commodo dui eget wisi.

htmlContent += 'Morbi a metus. Phasellus enim erat, vestibulum vel, aliquam a, posuere eu, velit. <br>Nullam sapien sem, ornare ac, nonummy non, lobortis a, enim. Nunc tincidunt ante vitae massa. <br>Duis ante orci, molestie vitae, vehicula venenatis, tincidunt ac, pede. <br>Nulla accumsan, elit sit amet varius semper, nulla mauris mollis quam, tempor suscipit diam nulla vel leo. <br>Etiam commodo dui eget wisi.

htmlContent += '</body></html>';

var wvDemo = Titanium.UI.createWebView({
    html:htmlContent,
    backgroundColor:'transparent',
    borderRadius: 1, // As recomended by Appcelerator docs, to force chromium (Android) rendering 
    scalesPageToFit:false
});

win.add(wvDemo);

win.open();

我使用经典项目模板由Studio创建一个项目，并为此更新de app.js代码。当我使用SDK 6.0.1.GA或以前的版本进行编译时，该应用程序运行得非常好，速度很快。但是，如果我使用6.0.2.GA或更高版本编译，应用程序运行非常非常慢，并且许多消息如“[INFO]：Choreographer：Skipped 36 frames！应用程序可能在其主线程上做了太多工作。 “生成。

请问，有什么建议吗？提前谢谢。

在使用Ti SDK 6.0.2及更高版本的Android上，Webview非常慢
