本文介绍了拒绝对先前失败的类java.lang.Class< android.support.v4.view.ViewCompat $ OnUnhandledKeyEventListenerWrapper>进行重新初始化supportLib = 28的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当我切换到supportLibrary 28时，开始出现这种奇怪的logcat消息，而在27.1.1上没有发生.我尝试了一个空的默认项目，结果完全一样.
This weird logcat messages started when I switched to supportLibrary 28, not happens on 27.1.1. I tried with an empty default project and the result exactly the same.
问题很容易重现，
创建一个活动为空的新项目，并在除API28仿真器之外的仿真器上运行.它将在我的API21模拟器上给出该错误:
Create a new project with an empty activity and run on an emulator except API28 emulator. It'll give that error on my API21 emulator:
Rejecting re-init on previously-failed class java.lang.Class<android.support.v4.view.ViewCompat$OnUnhandledKeyEventListenerWrapper>
我的API24设备显示了更详细的日志:
My API24 device shows more detailed log:

我尝试了API21仿真器，API24硬件设备和API 28仿真器.只有API28仿真器不会产生该错误.
I tried API21 emulator, API24 hardware device and API 28 emulator. Only API28 emulator didn't produce that error.
我用Google搜索，搜索，还向 android问题跟踪器报告，我找不到任何内容解决方案和android小组说这是预期的行为.所以我不知道该怎么办.我应该忽略错误消息吗?有人有这个问题吗?
I googled, searched SO and also reported to android issue tracker I can't find any solution and android team says that is an intended behavior. So I don't know what to do. Should I ignore an error message? Is there anybody have this issue?

推荐答案
好吧，因为Google似乎无意对其进行修复；我已经决定(暂时)强制使用支持库27.至少它可以修复少数支持lib 28崩溃的设备上的崩溃.
Well, as it appears that Google isn't interested in fixing it; I've decided to (for now) force using support library 27; at least it fixes the crashes on the few devices that support lib 28 crash on.
我正在使用的修复程序是将以下内容添加到build.gradle中，但是请注意，这是针对android的修复程序；仅适用于com.android.support库的用户.
The fix that I'm using is adding the following into build.gradle however note, this is for a fix for android; only works for users of com.android.support libraries.
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == "com.android.support") {
if (!requested.name.startsWith("multidex")) {
details.useVersion "27.+"
}
}
}
}
