使用 Proguard 编码 android 代码时出错

Question

我正在使用 proguard 来保护我的 android apk 免受逆向工程的影响。

但是当我完成了在我的应用程序中使用 proguard 工具所需的所有步骤时，它会给出如下错误：

[2014-03-11 10:55:04 - DemoProApp] Proguard returned with error code 1. See console
[2014-03-11 10:55:04 - DemoProApp] proguard.ParseException: Expecting type and name instead of just '***' before '(' in line 85 of file 'D:\Ranjana\New folder\DemoProApp\bin\proguard.txt',

我的 Proguard-project.txt 文件如下所示：

Answer 1

错误消息是指文件proguard.txt（不是proguard-project.txt）的第85行。该行似乎在返回类型（通配符 ***）和方法参数的左括号之间缺少方法名称。

请注意，现在的 Android SDK 包含一个标准配置文件，该文件已经为您指定了所有通用 Android 配置（使用 -printseeds、-keepattributes 等）。
