What is the default font family in Android?
<p>Starting in API 16, Jellybean Roboto was introduced as available font family to use. See whats "new" in Android 16 <a href="https://developer.android.com/about/versions/android-4.1.html#Fonts" rel="noreferrer">here</a>.</p>

<p>Specifying <code>android:fontFamily="sans-serif"</code>(Roboto in API 16+) on a <code>TextView</code> the default <code>fontFamily</code> of the <code>TextView</code>?</p>

<p>Is </p>

<pre><code>&lt;TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" /&gt;
</code></pre>

<p>equivalent to</p>

<pre><code>&lt;TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:fontFamily="sans-serif" /&gt;
</code></pre>

<p>?</p>

<p>From <a href="https://material.google.com/style/typography.html#" rel="noreferrer">Material design typography website</a>: </p>

<blockquote>
  <p>"Roboto and Noto are the standard typefaces on Android and Chrome."</p>
</blockquote>

<p>From <a href="https://en.wikipedia.org/wiki/Roboto" rel="noreferrer">Wiki</a>, </p>

<blockquote>
  <p>"Roboto is a sans-serif typeface family developed by Google as the
  system font for its mobile operating system Android."</p>

<p>I do not see in the docs what the default <code>fontFamily</code> of Android is. See references:</p>
