android – 使用ProGuard进行模糊处理后,应用程序崩溃了

过去3天我一直在解决这个问题.

我的应用程序已经完成,在一些设备和模拟器上进行了测试,并准备发布…或者我认为.在导出和签名之后(顺便说一句,我使用带ADT的Eclipse),它会在任何设备或模拟器中停止工作.我认为问题在于我的ProGuard配置,因为如果我在project.properties中禁用ProGuard,它在导出后会完美运行.

这是我的project.properties：

# Project target.
target=android-23
android.library.reference.1=..\\google-play-services_lib
android.library.reference.2=..\\android-support-design
proguard.config=proguard.cfg

(如果我jusst评论上面的proguard.config =行,那么导出后一切正常)

proguard.cfg：

我的应用有一个TabLayout和4个标签的活动.第一个选项卡始终成功打开.如果我切换到另一个选项卡(更改片段),我会得到上面的错误.即使切换到的片段中没有Button视图,我也会得到相同的错误.

在此先感谢您的帮助.过去3天我一直在努力解决这个问题.

解决方法

我解决了问题.

这是我最终得到的最终proguard.cfg文件,它编译了几个优化并使我的应用程序顺利运行：

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-verbose
-dontpreverify
-allowaccessmodification
-mergeinterfacesaggressively
-overloadaggressively
-keepattributes *Annotation*

我将这个放在这里作为我自己问题的答案,因为上面的配置可能会帮助那些也失去时间并且使用ProGuard睡觉的人.

部分优化是从此页面获取的：

上面的页面提供了几个特定于库的ProGuard配置的集合,包括android.support.v7和android.support.design.
