Custom shape(rounded square) drawable android

Question

I want custom shape border like the one shown below:

This is what i have tried so far:

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#00000000"/>
    <stroke android:width="0.1dp" android:color="#FFFFFF" />
    <corners android:radius="5dp"/>
    <!--<padding android:left="5dp" android:top="5dp" android:right="5dp" android:bottom="5dp" />-->
</shape>

But this does not give me curvy sides,only curvy corners.

I need curvy sides

Look at this when change the drawable to this you will get the following output.

 <ImageView
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_marginLeft="100dp"
            android:layout_marginTop="25dp"
            android:src="@drawable/rectangle" />

rectangle.xml file is

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#000000" />
    <stroke
        android:width="1dp"
        android:color="#FFFFFF" />
    <corners android:radius="20dp" />
    <padding
        android:bottom="5dp"
        android:left="5dp"
        android:right="5dp"
        android:top="5dp" />
</shape>
