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
(导出后一切正常,如果我对上面的proguard.config =行进行评论)
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。
提前感谢您的帮助。过去3天我一直在努力解决这个问题。
答案 0 :(得分:15)
我的问题解决了。
这是我最终的最终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*

我将此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。
部分优化措施来自此页面:

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。
