I understand I can add a shadow to it that will look like a border, with:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:shadowColor="@color/black"
android:shadowRadius="10" />
But that shadow has a certain amount of blur to make it look shadowy that I don't know how to remove. How can I add a border to my characters, just like that shadow, in a way that it doesn't look like a shadow, but like a border?
Example:
