问题描述
我有一个带有 QR 扫描活动的 android 项目.我为此使用 ZBar 库:http://sourceforge.net/projects/zbar/files/AndroidSDK/
I have an android project with a QR scan activity. I use the ZBar library for this: http://sourceforge.net/projects/zbar/files/AndroidSDK/
如果项目是在带有 exlipse 的 PC 或 Mac 上构建的，则该应用程序运行良好.如果它是由 jenkins(来自 git 的相同来源)构建的，应用程序就会崩溃.
If the project is built on a PC or Mac with exlipse, the app works fine.If it's build by jenkins (same source from git) the app crashes.
我得到的异常是:

我使用演示应用程序作为基础.
I used the demo app for a base.
这是 Jenkins 配置问题吗?
Is this a Jenkins config problem?
Zbar 库不仅仅是一个 jar 文件，它还是一个带有 jni 的 C 库.所以我有一个 jar 文件和 3 个文件夹(我认为适用于不同的架构)，它们有一个 libiconv.so 和一个 libzbarjni.so 文件.
The Zbar library is not just a jar file, it's a C library with jni. So I have a jar file and 3 folders (for different architectures I think) and they have a libiconv.so and a libzbarjni.so files.
推荐答案
添加 -keep class net.sourceforge.zbar.** { *;} 到你的 proguard 配置文件
Add -keep class net.sourceforge.zbar.** { *; } to your proguard config file
