AnyChartView doesnot show at all in UI

[androidDev2016]

When I add this in my layout file of a Fragment in Android Studio:

<com.anychart.AnyChartView
android:id="@+id/anyChartView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
the whole XML file shows blank in the IDE, remove it, all UI components show as expected. Though, I don't get error when adding the above component in the XML file. But when running it, the Pie Chart is not shown at all in screen. Here's the setting in

app/build.gradle:

implementation 'com.github.AnyChart:AnyChart-Android:**1.1.2**'
//implementation('androidx.multidex:multidex:2.0.1') // with or without this line, Pie Chart is not shown in screen

(I noticed it's 1.1.5 in this link: https://github.com/AnyChart/AnyChart-Android/wiki/Getting-started, but my Android Studio is Electric Eel which is on Java 11 instead of 17, so I used 1.1.2)

I have to put "maven { url 'https://jitpack.io' }" in settings.gradle instead of allprojects{ } in root build.gradle to make it build successfully:

include ':app'
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
jcenter()
mavenCentral()
maven {
maven { url 'https://jitpack.io' }
}
}
}

This is how I draw the Pie Chart, pretty much copy from Getting Start link:

private void drawPieChart() {
AnyChartView anyChartView = getActivity().findViewById(R.id.anyChartView);

    Pie pie = AnyChart.pie();

    List<DataEntry> data = new ArrayList<>();
    data.add(new ValueDataEntry("Apples", 6371664));
    data.add(new ValueDataEntry("Pears", 789622));
    data.add(new ValueDataEntry("Bananas", 7216301));
    data.add(new ValueDataEntry("Grapes", 1486621));
    data.add(new ValueDataEntry("Oranges", 1200000));

    pie.data(data);
    anyChartView.setChart(pie);
}

It sounds like it's caused by the fact : the component
<com.anychart.AnyChartView
android:id="@+id/anyChartView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
is not shown in xml layout in design view.

Not sure where to go at this point... Documentation is so limited and ambiguous, searching in web doesn't provide any helpful results at all.

it looks like I have to set absolute height like this:

                        <com.anychart.AnyChartView
                            android:id="@+id/anyChartView"
                            android:layout_width="match_parent"
                            android:layout_height="match_parent"
                            />
                    </LinearLayout>

though the layout file is still blank, but Pie Chart appears when running the app.
