我已将项目的minSdkVersion从19更新为21.这导致5.0/5.1设备上的问题,我无法运行该应用程序.我一直在我的Application类上得到一个ClassNotFoundException.完整日志,应用程序类和gradle文件如下所示.如果我将我的项目还原为minSdkVersion 19,那么应用程序将在4.4+上运行,没有任何问题.

我试过了什么

• 清洗/重建

• 更新和降级构建工具版本

• 跨项目的所有支持库都具有相同的版本号

• 使我所有的清单类相对而绝对

• 更新了所有Sdk和构建工具

在gradle中添加facebook依赖项后,我收到此运行时错误:

     compile 'com.facebook.android:facebook-android-sdk:4.6.0'

请注意我也在使用okhttp:

    compile 'com.squareup.okhttp:okhttp:2.5.0'

和错误日志是:

注意:我在三星手机4.4上遇到此错误,但在模拟器上moto g 5.0并且运行正常.

我们最近将应用程序的minSdkVersion从16(Jellybean)提升到了21(Lollipop).虽然我们主要使用调试版本对我们的应用程序进行了大量测试,但我们现在面临着应用启动时的大量生产崩溃,主要是在较旧的三星设备上 - (Note3和S4是顶级的crashers)并且总是在Lollipop上.

错误是

SplashActivity是应用程序的初始启动活动.未找到的课程是一个历史悠久的课程,而不是新引入的课程.作为旁注,作为最新版本的一部分,我们升级到Android Studio 3并引入了Kotlin代码,但我不认为这些与此问题有关.我们没有在构建中使用proguard.

我知道当minSdkVersion为21及以上,与使用ART而不是Dalvik有关时,构建发生了重大变化,所以我想知道三星Lollipop设备是否还有一些缺陷正在寻找现在的主要dex文件？
