得到 java.lang.RuntimeException ... 原因：java.lang.ClassNotFoundException 从 Google Play 安装后首次启动应用程序

Question

迁移到androidX后，开始出现RuntimeException。按照此处的说明进行操作 https://developer.android.com/jetpack/androidx/migrate 和这里 https://developer.android.com/jetpack/androidx/migrate#migrate 迁移现有项目在我构建 .apk（用于发布）并在本地安装它之后，一切都很好。但是在我将 .apk 上传到 Google Play 并在首次启动应用程序时从 GP download/install 上传它后，我收到了这个错误

java.lang.RuntimeException:

关闭应用程序重新启动它，一切正常......我搜索了很多但找不到任何解决方案为什么会发生这种情况。只有从 GP 下载后，我才能在本地复制它。这是我的build.gradle(Module: app)，只是重要的部分

 defaultConfig {
        applicationId "com.xxxxxxxx not important xxxxxxxx"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 3
        versionName "1.2"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.google.android.gms:play-services-ads:18.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.squareup.picasso:picasso:2.5.2'
    implementation 'jp.wasabeef:picasso-transformations:2.2.1'
    implementation 'com.android.support:palette-v7:28.0.0'
    implementation 'com.jakewharton.picasso:picasso2-okhttp3-downloader:1.0.2'
    //recycleview library
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    //cardview library
    implementation 'com.android.support:cardview-v7:28.0.0'
    //circle indicator
    implementation 'me.relex:circleindicator:1.2.2'
    implementation 'com.google.code.gson:gson:2.8.5'

}

这是我的manifest.xml

 <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

        <uses-library android:name="org.apache.http.legacy" android:required="false"/>

        <meta-data
            tools:replace="android:value"
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="xxxxxxxxxxx"/>

清单的其余部分仅为活动列表。

我只是不明白为什么这种情况只发生在应用程序的第一顿午餐，接下来的每一顿午餐都很好。一些建议??
