proguard.ParseException:类成员名称应在'@'；在Android Eclipse ADT中

我尝试在MAC上使用Proguard和eclipse ADT v21.1.0-569685优化我的Android应用程序代码。 我使用project->Android Tools->export-asigned Application package选项使用我的私人证书进行签名，在签名完成后，我得到以下错误：

如何解决上述问题

我在prouard.project文件中读到

如果您的项目使用带JS的WebView，请取消注释以下内容并 指定JavaScript接口的完全限定类名 类别：

---

我在WebAppInterface.java类的两个活动中使用了webview。如何执行上述语句？

在android:onClick布局文件的属性中引用资源名称，如“@string/on\u click\u handler\u name”。但是，proguard无法解析这些引用。

查看更多详细信息

在string.xml中找到@string/tha_lf_et_todate_onclick的相应值并更新：

android:onClick="@string/tha_lf_et_todate_onclick" 

到

在布局文件中。 关于第二个问题， 取消注释这段代码，并替换“fqcn.of.javascript.interface.for.webview”

---

使用类的完全限定名。

您看过

/Users/MyOrg/Android\u workspace/MyApp/bin/proguard.txt

的第82行了吗？-keepclassmembers类*{***@string/tha_lf_et_todate_onclick（…）}

android:onClick="onClickXXX"
