那些遇到过的问题

在先前失败的类java.lang.Class <android.support.v4.view.ViewCompat $ OnUnhandledKeyEventListenerWrapper> supportLib = 28上拒绝重新初始化

Sin*_*lan 27 android

这个奇怪的logcat消息在我切换到supportLibrary 28时启动,而不是在27.1.1上发生.我尝试了一个空的默认项目,结果完全一样.

问题很容易重现,

使用空活动创建一个新项目,并在除API28模拟器之外的模拟器上运行.它会在我的API21仿真器上给出错误:

Rejecting re-init on previously-failed class java.lang.Class<android.support.v4.view.ViewCompat$OnUnhandledKeyEventListenerWrapper>

我的API24设备显示更详细的日志:

我尝试了API21仿真器,API24硬件设备和API 28仿真器.只有API28仿真器没有产生该错误.

好吧，看来 Google 对修复它不感兴趣。我决定（现在）强制使用支持库 27；至少它修复了支持 lib 28 崩溃的少数设备上的崩溃。

我正在使用的修复是将以下内容添加到 build.gradle 中，但请注意，这是针对 android 的修复；仅适用于 com.android.support 库的用户。

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "com.android.support") {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "27.+"
            }
        }
    }

当使用与您的最低 sdk 版本不兼容的类时，就会发生这种情况。该代码可以编译，因为它让您自行部署。尝试使用更高的最低 sdk 版本来验证这一点。

  • 感谢您的回答，但这不是较低 API 设备的解决方案。我在问题中提到过这一点。 (3认同)
