不要混淆Proguard中的硬编码字符串

我将使用proguard混淆源代码。

我的源代码定义了一些硬编码字符串，但我不知道如何防止proguard混淆我的String值（在下面的示例中为“ tbl_people”）

类

public class MyDaoObject {
  public static final String TABLENAME = "tbl_people"; 
  //other database code
}

如果字符串混淆，SQLite将无法使用该字符串创建表。有很多像这样的硬编码字符串。如何配置proguard来做到这一点？

任何建议都欢迎。

我认为问题来自字符串，因为当我保留处理数据库的类时，我的应用程序不再崩溃！

更新2：问题不是来自字符串值，而是字符串名称。这是我的问题：https : //groups.google.com/forum/#!msg/greendao/tyqjrx2otVo/PHExbn4iZk8J
