<h2 id="emoji">New Emojis</h2>
<p>
Android N introduces new emojis, including skin tone emojis, support
for variation
selectors, and other improvements. For a good user experience, observe the
following guidelines for using the new emojis and emoji features in your apps.
</p>
<ul>
<li>
<strong>New emojis</strong>: To check which emojis are present in the
system font, use the {@link android.graphics.Paint#hasGlyph(String)} method
and the dynamic layout in the emoji picker to place the glyphs.
</li>
<li>
<strong>Variation selectors</strong>: Variation selectors allow certain
emojis to be represented in color or in text presentation, which is used in
documents. For mobile devices, emojis should use their color representation.
To determine whether an emoji has a variation, use the variation selector.
You can view the complete list of characters with variations in the
<em>emoji variation sequences</em> section of the
<a href="http://www.unicode.org/Public/9.0.0/ucd/StandardizedVariants-9.0.0d1.txt">
Unicode documentation on variations</a>.
</li>
<li>
<strong>Skin tone modifiers</strong>: In Android N, users can modify the
rendered skin tone of emojis. This allows users to customize the presentation
of emojis to their preference. Keyboard apps should provide visual
indications for emojis that have multiple skin tones and should allow users to
select the skin tone that they prefer. To determine which system emojis have
skin tone modifiers, use the {@link android.graphics.Paint#hasGlyph(String)}
method. You can determine which emojis use skin tones by reading the
<a href="http://unicode.org/emoji/charts/full-emoji-list.html">
Unicode documentation</a>.
</li>
</ul>
