Android项目用ProGuard混淆后报错:NoSuchMethodError的错误
各位高人，小弟有一个项目不混淆运行正常（环境是：Eclipse, Android 2.3.3），如何解决该问题，请高手赐教，多谢！用ProGuard混淆后运行报错如下：
java.lang.NoSuchMethodError:android.util.Xml.newSerializer
at com.abcsoft.abc.a(UnKnown Source)
at ...
在 com.abcsoft.abc.a 类中的代码：
public boolean createConfigXmlFile(String webURL,int iAisID,String strAisName,String strAisPosition,int iUserID,String strUserName,String strPassword )
{
File linceseFile = new File(K3ConfigFile_PATH);
//如果已存在，则先删除
if(linceseFile.exists())
{
linceseFile.delete();
}
try{
linceseFile.createNewFile();
FileOutputStream fileos = null;
fileos = new FileOutputStream(linceseFile);
// 混淆后，运行到这句报错，Xml 是 android.util中的类 newSerializer方法的修饰符是:public static
XmlSerializer serializer = Xml.newSerializer();
serializer.setOutput(fileos,"UTF-8");
serializer.startDocument(null, true);
....
serializer.endDocument();
serializer.flush();
fileos.close();
return true;
}
catch (FileNotFoundException e) {
Log.e("FileNotFoundException", "can't create FileOutputStream");
return false;
}
catch (IOException e) {
Log.e("IOException", "exception in createConfigXmlFile() method");
return false;
}
catch (Exception e) {
Log.e("Exception","error occurred while creating xml file");
return false;
}
}
我的ProGuard.cfg 的内容如下：

-injars lib
-outjars bin/classes-processed.jar

看样子是 XmlSerializer的构造函数被混淆掉了-keep public class android.util.Xml.newSerializer {
protected <methods>;
public <methods>;
public static <methods>;
}
强制keep下试试
