    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation fileTree(dir: 'libs', include: ['*.jar'])

For sdk 28 you need use: java.lang.Object ↳ androidx.core.app.NotificationCompat

Despite you have implementation 'com.android.support:appcompat-v7:28.0.0' in your build gradle, the class path is android.support.v4.app.NotificationCompat.Action (not v7.app...)

You can also confirm HERE (Note the V4 on the package path).

So, just update your method to:

protected android.support.v4.app.NotificationCompat.Action getStopAction() { ... }
