我尝试在 MAC 上使用带有 eclipse ADT v21.1.0-569685 的 Proguard 优化我的 Android 应用程序代码。我使用项目-> Android 工具-> 导出已签名的应用程序包选项来使用我的私人证书进行签名，签名完成后出现以下错误，

  1. 如何解决上述问题？
  2. 在我阅读的 prouard.project 文件中

如果您的项目使用带有 JS 的 WebView，请取消注释以下内容并将完全限定的类名指定给 JavaScript 接口类：

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

在布局文件的android:onClick属性中引用资源名称如“ @string/on_click_handler_name ”是可以的。但是，proguard 无法解析这些引用。

查看http://android.okhelp.cz/proguard-parseexception-expecting-class-member-name-before/了解更多详情。

在您的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"

至

android:onClick="onClickXXX"

在您的布局文件中。对于第二个问题，取消注释那段代码，并将“fqcn.of.javascript.interface.for.webview”替换为类的完全限定名称。
