Android 9.0 Emoji Changelog
Google has begun rollout of their new OS update, Android 9.0, also known as Android Pie[1]. Contained within this release are Googleโs Emoji 11.0 updates as well as numerous tweaks to existing emoji designs.
With the release of Android 9.0, Google is the second major vendor to provide support for the 157 new emojis featured within Emoji 11.0, following the Twemoji 11.0 release in June.

Above: Googleโs designs for the six new smiley emojis from Emoji 11.0: ๐ฅฐ Smiling Face With 3 Hearts, ๐ฅด Woozy Face, ๐ฅต Hot Face, ๐ฅถ Cold Face, ๐ฅบ Pleading Face and ๐ฅณ Partying Face.
As previewed during the testing period of Android P Beta 2, several noteworthy tweaks have been made to several emoji from earlier releases. These include the ๐ซ Pistol changing to a toy squirt gun in a move expected to be echoed by all major vendors by the end of the year.

Above: From firearm to orange water pistol: Googleโs new ๐ซ Pistol emoji design.
As well as this, ๐ช Family and ๐ Couple With Heart have been modified to display gender-inclusive designs, as opposed to sharing the imagery of the ๐จโ๐ฉโ๐ฆ Family: Man, Woman, Boy and ๐ฉโโค๏ธโ๐จ Couple With Heart: Woman, Man emojis respectively.


The ๐ข Turtle emoji is now more alert and appears to have regained some of its old amicability, the ๐ก๏ธ Dagger now glistens blue like Frodo's Sting, and the ๐ฅ Green Salad (somewhat controversially) no longer includes egg in its ingredients list, making it vegan-friendly.
All of these previous design changes have now officially been released with Android 9.0.



New
The introduction of the ๐จโ๐ฆฐ Red Haired Man and ๐ฉโ๐ฆฐ Red Haired Woman emojis have easily been one of Emoji 11.0's most anticipated features. However, Emoji 11.0 also features people with curly hair, people with silver hair, and bald people.

Above: Google's four new hair style emoji designs for both men and women. Each support the five Fitzpatrick Scale skin tone modifiers.
These hair styles are created through combining either ๐จ Man or ๐ฉ Woman with one of four new "emoji component" code points in what is known as a ZWJ sequence. Unlike Twemoji, Google has opted to provide each of these components with stand-alone designs, as shown below.

Above: Google has given graphic representation to the new ๐ฆฐ Emoji Component Red Hair, ๐ฆฑ Emoji Component Curly Hair, ๐ฆณ Emoji Component White Hair and ๐ฆฒ Emoji Component Bald code points.
Also included in Emoji 11.0 are the ๐ฆธ Superhero and ๐ฆน Supervillain. In designing these emojis, Google has made some less-than-subtle nod to our world's two major comic book publishers.

Above: The man and woman variants of ๐ฆธ Superhero and ๐ฆน Supervillain. All support skin tone modifiers, though the ๐ฆน Supervillain designs default to a ghastly white instead of the standard yellow.
Both ๐ฆธโโ๏ธ Man Superhero and ๐ฆธโโ๏ธ Woman Superhero show a hero jumping into action with a blue suit and flowing red cape, very reminiscent of DC's man (and women) of steel. Meanwhile, the ๐ฆนโโ๏ธ Man Supervillain and ๐ฆนโโ๏ธ Woman Supervillain pose with full-bodied evil intent while their shoulder pads feature adornments clearly inspired by the classic design of Marvel's Mr. Sinister.[2]
New animal and foodstuff emoji are always warmly welcomed. Emoji 11.0 features sixteen new emojis across these two categories.

Above: The ten new animal emoji from Emoji 11.0, including ๐ฆ Kangaroo and ๐ฆ Lobster. It's noteworthy that ๐ฆก Badger and ๐ฆ Hippopotamus are rendered as forward-facing heads, unlike their whole-bodied Twemoji 11.0 counterparts.

Body parts, science objects and household paraphernalia are also featured alongside other more stand-alone additions such as the ๐น Skateboard and the ๐งฟ Nazar Amulet).

Above: A selection of Google's Emoji 11.0 designs.
Notable design choices present within the select above include ๐ฆ Microbe being represented as five of the tiny creatures as opposed to just one, ๐งฉ Jigsaw showing two jigsaw pieces and ๐งฑ Brick displaying an entire brick wall as opposed to a single block.
Changed
Several of the smiley face emojis have had subtle design changes in Android 9.0. Two that are worth highlighting here are ๐ค Hugging Face and ๐ Upside-Down Face.
๐ค Hugging Face now has its hands facing outwards, which is how a majority of major vendors display this emoji. This is less hug-like, but more compatible with the common use as 'excited / jazz hands'.

๐ Upside-Down Face has had its gradient inverted to match those of the other smiley faces, as discussed on a recent episode of the Emoji Wrap podcast, featuring Google's Jennifer Daniel.

๐คจ Face With Raised Eyebrow now raises the opposite end of the right eyebrow.

Other smileys with minor design changes include ๐ช Sleepy Face (lowered eyebrows), ๐ค Cowboy Hat Face (wider grin), ๐คฅ Lying Face (longer nose) and ๐ฑ Face Screaming in Fear (eyebrows removed).
๐ Dog and ๐ถ Dog Face has been tweaked with ears shortened, tongue lengthened, and their face rounded for all an overall more cute-and-pudgy look.

๐ช Camel has a more proportionate head and hump.

๐ฆ Giraffe now displays the full animal rather than just the head.

๐ Full Moon Face and ๐ New Moon Face have been changed into astronomical versions of the ๐ Smirking Face, reflecting the sideways glance shown on iOS and WhatsApp.

๐ Sun With Face has a more subtle smile, somewhat akin to the ๐ Slightly Smiling Face

๐ถ๏ธ Sunglasses now appears with the same design as shown on ๐ Smiling Face With Sunglasses.

๐ฃ Bomb had its fuse tweaked, now appearing more obviously lit.

๐ฅ Bacon is no longer a raw piece of bacon, and is instead shown cooked and therefore ready for human consumption.

โพ๏ธ Baseball has had its stitching increased in size to match the new ๐ฅ Softball emoji.

๐ฅ Hospital now shows an outlined red cross instead of a solid red cross[3]

Release
Android 9.0 is out now for those with eligible devices, with rollout continuing over the coming months.
As with all Android releases, this will only reach the subset of devices whose carriers and/or device-makers support the latest software updates. Additionally, Samsung devices use their own emoji font and therefore will not be eligible for this update.
Editor's note: It appears that some builds of Android 9.0 include only a subset of these changes. For users with these builds, the same updates may appear in a future release.
This is similar to how the ๐จโ๐ค Man Singer and ๐ฉโ๐ค Woman Singer
appear-like-but-not-as David Bowie across most vendors and, in the case of WhatsApp, Prince. โฉ๏ธPerhaps related to the Red Cross and its known efforts to ensure this design isn't used for โgeneral signs of ambulances, health care, first aid, the nursing or medical profession, or similar mattersโ โฉ๏ธ
