在一个使用Androidx:appcompat:appcompat:1.0.0-rc01新建的项目中,我得到了
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.+"
}
}
}
}
这不影响应用功能或崩溃。但是在应用程序运行时始终会出现此错误。请帮助我解决错误。 整个堆栈跟踪如下。

答案 0 :(得分:34)
正如ALFlanagan在评论中提到的,问题是android.support.v4.view.ViewCompat
并未在新的androidx包结构中实现View.OnUnhandledKeyEventListener
,而仅从支持lib结构中的API 28开始实现(至少在版本28.0.0)。因此,该警告会在API <28的设备上显示,而在> = 28的设备上不会显示。
这是支持包结构中ViewCompat.class
类中的相关代码:
@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方法来解决此警告。
答案 1 :(得分:11)
我遇到了同样的问题,但只是尝试升级appcompat的依赖项,因此不再处理错误日志。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
实现'androidx.appcompat:appcompat:1.3.0-alpha02'
答案 2 :(得分:0)
我认为这是androidx中的错误。我发现该错误会导致调试版本出现滞后,但没有显示或降低生产版本,因此我暂时将其忽略。
答案 3 :(得分:0)
以上答案是正确的。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。坏消息是新材料库都参考并遇到了问题。我不希望在启动时发生这种情况-以后的点击率还算不错。这只是一个警告-但确实会对性能产生影响,并且非常虚假,并且无法被大G处理器处理。
答案 4 :(得分:0)
注解@RequiresApi(28)
实际上意味着,摆脱日志垃圾邮件的唯一build.gradle
配置是将minSdkVersion
至少提高到28
。只是将其视为无法忽略的警告-不是错误。
android {
defaultConfig {
targetSdkVersion 28
compileSdkVersion 28
minSdkVersion 28
}
}

您可以使用AspectJ通过修改androidx字节码来消除此问题。
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();
}
}
}
答案 6 :(得分:-3)
您可以避免这种情况,因为该特定类仅在Android 9中提供。
