Android应用崩溃三星棒棒糖设备上的NoClassDefFoundError
问题描述：
我们最近将我们的应用的minSdkVersion从16（Jellybean）撞到了21（Lollipop）。尽管我们的应用程序主要使用调试版本进行了大量测试，但我们现在面临着应用程序启动时的大量生产崩溃，主要是旧三星设备 - （注3和S4是最糟糕的），并始终在棒棒糖上。Android应用崩溃三星棒棒糖设备上的NoClassDefFoundError
该错误是

的SplashActivity是应用程序的初始空空活性。没有找到的班级是一个历史悠久的班级，而不是新引入的班级。作为最新版本的一部分，我们升级到了Android Studio 3并引入了Kotlin代码，但我不认为这些与这个问题有关。我们没有在构建中使用proguard。
我知道，当minSdkVersion是21岁及以上，与使用ART而不是Dalvik有关的构建有重大变化，所以我想知道是否有一些缺陷与三星棒棒糖设备仍然看现在为主要的dex文件中的类吗？

答
此此修复程序是停用预德兴：
dexOptions {
preDexLibraries false
}
。灵感这个来自关于在棒棒糖未找到毕加索类错误此链接：see here
它并不完全清楚，我为什么禁用预德兴解决了这个问题，但我只能推断，有一些优化与回事构建过程会影响apk的dex文件中的类的排序方式，从而影响这些Samsung Lollipop设备上的应用程序安装。理论上ART应该照顾所有这些，但显然在pre-dex优化和一些棒棒糖设备之间存在依赖关系。
