Half circle shape not work

Question

I try to create half circle background, in development IDE preview it works, but when I launch in emulator it doesn't work.

Here is my shape code :

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:height="50dp">
        <shape>
            <solid android:color="@color/colorAccentDark" />
        </shape>
    </item>
    <item android:top="-500dp" android:bottom="0dp" android:left="-100dp" android:right="-100dp">
        <shape>
            <corners android:radius="500dp" />
            <solid android:color="@color/colorAccentDark" />
        </shape>
    </item>
</layer-list>

And here is my layout code :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/background_profile"
        android:layout_weight="1">

        <de.hdodenhof.circleimageview.CircleImageView
            android:id="@+id/profile_avatar"
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:src="@drawable/ic_default_avatar"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="50dp"/>

        <TextView
            android:id="@+id/profile_name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_below="@id/profile_avatar"
            android:layout_marginTop="20dp"
            android:textColor="@color/neutralWhite"
            android:textStyle="bold"
            android:textSize="18sp"
            android:text="Avatar Ang"/>

    </RelativeLayout>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="4.04">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Hello Android!"/>

    </RelativeLayout>

</LinearLayout>

Maybe any other tweak to handle that? Thank you

you can try this :

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#900021df"/>
    <size
        android:width="10dp"
        android:height="5dp"/>
    <corners
        android:bottomLeftRadius="20dp"
        android:bottomRightRadius="20dp"/>
</shape>

it gives this shape:
