java.lang.RuntimeException : Unable to instantiate application com. chiaramail.chiaramailforandroid.K9

Question

我已将此应用多次上传到 Google Play，均未出现问题。我没有更改任何构建文件(我使用的是 Eclipse)，如果我从 IDE 安装它，它运行良好。然而，在我对 Google Play 进行最新更新后，当我尝试从那里安装它时(我必须先从设备上卸载它；不同证书签名存在某种问题)，它立即崩溃:

java.lang.RuntimeException: Unable to instantiate application com.chiaramail.chiaramailforandroid.K9: java.lang.ClassNotFoundException: Didn't find class "com.chiaramail.chiaramailforandroid.K9" on path: DexPathList[[zip file "/data/app/com.chiaramail.chiaramailforandroid-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.chiaramail.chiaramailforandroid-1, /vendor/lib, /system/lib]]

我检查了 Stack Overflow 上针对相同问题的所有答案，但都没有帮助。我对此束手无策，也许最糟糕的是，我什至无法取消 Google Play 上的更新，因为当我尝试时，出现错误:

This configuration cannot be published for the following reason(s):
It is forbidden to downgrade devices which previously matched version 4059 to version 4055, which would occur when 
API levels in range 13+ and 
Release track excluding all of [BETA] and 
Screen layouts containing any of [small, normal, large, xlarge].

这是我的 list 的相关部分:

list 也没有改变，除了 android:versionCode，我在构建之前递增了它。我的设备是 Samsung Galaxy S III 和 Galaxy Note 8.0，分别运行 Android 4.4.2 和 4.4.3。

Answer 1

由于某些未知原因，问题刚刚消失。我不知道如何，但它不再发生并且应用程序启动正常。可能是一个奇怪的不可重现的 Eclipse 错误；我讨厌发生这种情况。
