Android 打包几种报错情况和解决办法proguard returned with error code 1.

情况1：

Proguard returned with error code 1. See console

Error: C:/Documents (系统找不到指定文件)

这个是因为有空格引起的，proguard进行发编译的时候是不允许有空格的。所以要注意工程所放位置是否有空格。

如果换了正确路径还不好用的话，直接删除proguard就好了

注意：SDK和程序路径最好不要有空格符

情况2：

Proguard returned with error code 1. See console

异常：

java.lang.ArrayIndexOutOfBoundsException

解决办法：将proguard.cfg中的"-dontpreverify"改成“-dontoptimize”

把项目中生成的proguard文件夹（此时文件夹是空的）删掉，然后再重新运行项目，就OK 了。

情况3：

Proguard returned with error code 1. See console

抛出这样的异常的原因是第三方jar的引用路径不对，没有找到这个需要忽略混淆的jar包。

只需在你的proguard-project.txt中添加如下两行即可。

-ignorewarnings

-libraryjars libs/Android_Map_V2.0.4.jar

你可以根据你的项目提示，添加需要的jar。
下面是4.0打包办法！

其实Android 4.0要用ProGuard比2.3更简单：在Eclipse中打开工程目录下的project.properties文件，该文件中有以下两行：

To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):

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

根据这段说明，只要将proguard.config前面的#去掉，就可以利用ProGuard来混淆代码了！当然，默认的设置是不带优化功能的，可以用以下设置来加上代码优化功能：

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

然后只要经过数字签名之类的编译后，代码就是混淆的了。
