我已经收到了一个现有的Xamarin项目,在发布之前,我需要对其进行处理。
我尝试在两种不同的设备上安装它:
-
Nexus 5,运行Android 6.0(API 23)
-
Emulator Android 4.4(API 19)-通过Visual Studio Emulator for Android进行仿真
然而,每次我这样做时,它都会在启动时崩溃
java.lang.classNotFoundException: Didn't find class "md515fc9a7f42ec11c09d24b1c1a9770737.ConnectScreen"
(下面是完整的堆栈跟踪)
(ConnectScreen是我的主启动器)
我尝试过的事情:
-
删除bin/obj文件夹并重建
-
清理项目并重建
-
终止MSBuild进程,清理并重建
经过研究,我发现
Classy-Shark
,它允许我在
.apk
文件
由此看来,ConnectScreen似乎未在包中编译
md515fc9a7f42ec11c09d24b1c1a9770737
(应用程序正在查找)但是
md5bc065f6c935f653292ddf7352d29f8ad
. 我觉得这不对吗?
(每次我构建项目时,这两个包都会发生变化)
我曾尝试构建一个新项目(跨平台应用程序、本机、主细节、.NET标准),该项目在我的Nexus 5上运行良好,所以我不认为这是因为我的手机或Visual Studio版本?
我尝试过更改MultiDex设置以及TargetFramework,但仍然遇到同样的问题。
以下是完整的堆栈跟踪:
