Android :NoClassDefFoundError on KitKat

Question

请不要将此帖子标记为副本，我将在检查所有现有答案后添加此查询。

我面临的问题是java.lang.NoClassDefFoundError: android.support.v4.content.LocalBroadcastManager on Android 。我正在尝试用构建版本"28.0.3"构建并运行我的安卓代码，这对ApiVersion23-棉花糖很好，但是当我尝试用Kitkat版本19运行相同的代码时，会抛出NoClassDefFound错误。

我试图将我的应用程序迁移到AndoridX，就像安卓开发者网站中提到的那样，但这也不起作用。如能在此问题上提供任何帮助，将不胜感激。

在Api 23级上工作的最初的gradle依赖项，而不是19级上的

LocalBroadcastManager.getInstance(this).registerReceiver(broadcastReceiver, eventFilter);

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"

    defaultConfig {
        applicationId "com.example.amit"
        minSdkVersion 19
        targetSdkVersion 28
        multiDexEnabled true
    }
    .....
    .....
}

旧的支持库不再被维护。使用AndroidX的最新版本：

implementation 'androidx.localbroadcastmanager:localbroadcastmanager:1.0.0'

并从新包装进口：

import androidx.localbroadcastmanager.content.LocalBroadcastManager;
