java - HTMLUnit 不起作用

Question

我编写了一个使用 HTMLUnit 登录网站的程序，效果很好。现在我想在我正在构建的 Android 应用程序中使用它，但它不起作用。我收到此错误:

Conversion to Dalvik format failed with error 1

一旦我删除了一些 jar ，比如 Jetty jar ，我就会不断遇到这个错误

Could not find class 'com.gargoylesoftware.htmlunit.html.HtmlDivision', referenced from method com.gargoylesoftware.htmlunit.javascript.JavaScriptEngine.init

几秒钟后这个:

谁能告诉我这是怎么回事吗？谢谢

Answer 1

看看这个: "Conversion to Dalvik format failed with error 1" on external JAR

对此不是 100% 确定，但您可能需要使用以下方法将项目中引用的一些 jar 转换为 dalvik 格式:

dx --dex --output="c:\temp\dx.dex" "c:\temp\in.jar"

您收到 NoClassDefFoundError 错误可能是因为您从项目中删除了必要的 jar。
