Question

我希望自己的应用受到保护。为此，我通过一些教程，帖子，最后从this帖子开始，我知道我应该只这样做：

If you're using ADT 17 or newer, the documentation is slightly inaccurate. The generated file is proguard-project.txt and will be in the root directory of your project.

To enable Proguard, you will need to ignore the "do not modify" warning in project.properties and uncomment the following line:

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

在解除上述建议的行后，我试图导出未签名的应用程序。但是出现了导出错误progaurd returned error with code 1。当我单击错误对话框中的详细信息按钮时，我收到了如下所示的错误日志：

Proguard returned with error code 1. See console

知道为什么会这样吗？我正确配置progaurd还是错过了步骤？

Answer 1

根本原因列在堆栈跟踪中：

Caused by: java.io.IOException: Can't read [C:\Users\SURESH\Desktop\ActionBarSherlock-4.2.0\ABSlibrary\bin\abslibrary.jar] (Unexpected end of ZLIB input stream)
...
Caused by: java.io.EOFException: Unexpected end of ZLIB input stream 
    at java.util.zip.InflaterInputStream.fill(InflaterInputStream.java:223)
    ...

您应该检查以下内容：

文件abslibrary.jar是否出现在指定位置？
它是一个有效的jar（可以用一些解压缩工具打开它吗？）
是否在构建过程中编写？如果以某种方式异步编写，当ProGuard读取它时，它可能仍然不完整。

Answer 2

我通过注释-libraryjars解决了无法找到的jar的问题。文件说不会出现jar，它会在运行时加载jar。
