HtmlUnit很棒，在Java中至少我没有遇到任何问题。不幸的是，当将代码切换到Android平台时，当我尝试创建Web客户端时，它会给我错误。
import android.app.Activity;
import android.os.Bundle;
import com.gargoylesoftware.htmlunit.WebClient;
public class AndroidTestActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final WebClient webClient = new WebClient();
}
}
在程序启动AVD之前它给我的警告。
这是它给我的警告的一个例子，这是确切的警告，但它反复重复约100000次：
[2011-08-31 21:25:24 - AndroidTest] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class (org.apache.commons.collections.BeanMap$1) that doesn't come with an associated EnclosingMethod attribute. This class was probably produced by a compiler that did not target the modern .class file format. The recommended solution is to recompile the class from source, using an up-to-date compiler and without specifying any "-target" type options. The consequence of ignoring this warning is that reflective operations on this class will incorrectly indicate that it is not an inner class.
你能给我什么帮助吗？

我有类似的问题。经过一些研究，我发现这是由于命名空间冲突造成的。您必须重新编译htmlunit的源代码。我现在尝试这个，但是htmlunit是如此庞大和复杂，我还没有完成。

您的堆栈跟踪显示抛出ExceptionInInitializerError并且由以下原因引起：
Caused by: java.lang.NoClassDefFoundError: org.apache.commons.lang.StringUtils
也许你在类路径中遗漏了一些JAR（commons-lang）？
