解決 Rejecting re-init on previously-failed class <androidx.core.view.ViewCompat$2> 警告
新建一個安卓項目， compileSdkVersion 29，然後啟動MainActivity就看到 Logcat中有警告信息：
Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;雖然不會拋出錯誤或異常，但是看到也很噁心。
解決方法，在build.gradle文件中添加以下配置
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == "androidx.appcompat") {
if (!requested.name.startsWith("multidex")) {
details.useVersion "1.+"
}
}
}
