What does android:ems do?
What does ems in xml do? I saw that I was using following line in EditText. But, I never thought what it does. I was trying to check what actually it does by removing the line. I couldn't see any difference in my layout.

<span id="code">

```xml
android:ems="10"
```

</span>

Then I visited attributes.xml (AKA attrs.xml). I saw following lines.

```xml
<!-- Hint text to display when the text is empty. -->
<attr name="hint" format="string" />
```

It wasn't understandable for me. Cause whenever I remove [the line](#code) then I see no difference. I still can see hints of EditText.
