AndroidX:Appcompat I:art 错误 android.view.View$OnUnhandledKeyEventListener

Question

在 Androidx:appcompat:appcompat:1.0.0-rc01 新创建的项目中，我得到

java.lang.ClassNotFoundException: Didn't find class 
"android.view.View$OnUnhandledKeyEventListener" on path: DexPathList

我还添加了configuration.all

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "androidx.appcompat") {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "1.+"
            }
        }
    }
}

这不会影响应用程序功能或崩溃。但是当应用程序是运行时它总是有这个错误。请帮助我解决错误。整个堆栈跟踪如下。

Answer 1

你可以避免它，因为那个特定的 class 只在 Android 9.

Answer 2

这是 androidx 中的错误。我发现该错误会导致调试构建滞后，但不会显示或减慢生产构建。你可以暂时忽略它。

Answer 3

正如评论中提到的 A.L.Flanagan 问题是 android.support.v4.view.ViewCompat 没有在新的 androidx 包结构中实现 View.OnUnhandledKeyEventListener 并且只在 API 28 开始实现它在支持库结构中（至少在版本 28.0.0 中）。因此，警告会出现在 API <28 的设备上，而不会出现在那些 >=28.

的设备上

这是ViewCompat.classclass中的相关代码，来自支持包结构：

@RequiresApi(28)
private static class OnUnhandledKeyEventListenerWrapper implements OnUnhandledKeyEventListener {
    private ViewCompat.OnUnhandledKeyEventListenerCompat mCompatListener;

    OnUnhandledKeyEventListenerWrapper(ViewCompat.OnUnhandledKeyEventListenerCompat listener) {
        this.mCompatListener = listener;
    }

    public boolean onUnhandledKeyEvent(View v, KeyEvent event) {
        return this.mCompatListener.onUnhandledKeyEvent(v, event);
    }
}

我想不出任何简单的修复方法来解决这个警告。

Answer 4

以上答案正确。避免这种情况的唯一方法是删除对 AppCompat 的引用 - 例如我改为FragmentActivity。坏消息是新的 material 库都引用并遇到了这个问题。我不希望这种情况发生在我的初创公司 - 后来的打击并不那么糟糕。这只是一个警告 - 但确实会对性能产生影响，而且它非常虚假并且大 G 处理不当。

Answer 5

您可以使用aspectJ通过修改androidx字节码来解决这个问题。

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class UnHandleKeyEventAspectJ {
    public static final String TAG="UnHandleKeyEventAspectJ";
    @Pointcut("execution(* androidx.core.view.ViewCompat.setOnApplyWindowInsetsListener(android.view.View, androidx.core.view.OnApplyWindowInsetsListener))")
public void kotlinClassInit() {

}
    @Around("kotlinClassInit()")
    public void addTransaction(ProceedingJoinPoint joinPoint){
        try {
            joinPoint.proceed();
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
    }
}

Answer 6

我遇到了同样的问题，但只是尝试升级 appcompat 的依赖项，但它没有更多的错误日志。我希望很快会有新的稳定版本。 https://developer.android.com/jetpack/androidx/releases/appcompat#1.3.0-alpha02

实施'androidx.appcompat:appcompat:1.3.0-alpha02'
