Я использую CardView для реализации такого меню (уже перенесено на AndroidX): enter image description here

Это прекрасно работает на Android 6 и 8 устройствах , Но на Android 5 просмотры карт вообще не показываются. enter image description here

Я уже установил mindSdkVersion на 19. 

pply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.1"
    defaultConfig {
        applicationId "com.divbyzero.app.mytestapp999"
        minSdkVersion 19
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.android.volley:volley:1.1.1'
    implementation "com.google.android.material:material:1.1.0-alpha03"
    implementation 'androidx.cardview:cardview:1.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

Так это ошибка, связанная с ОС 5?
