It seems that Google is preparing to separate the new emojis from the updates of its Android operating system; So you can get it faster.
Emoji are important, as they help with better expression, and the frequent additions of new symbols to the Unicode standard are testament to their popularity.
Whenever the Unicode Consortium, a non-profit organization that deals with emoji publishing and approval, releases a new collection, there is enthusiasm to start using it in our apps and devices as soon as possible.
However, we often need to wait for Apple, Google, or the phone manufacturer to release an operating system update that includes the new batch.
This process may change for Android users, as there is now evidence indicating that Google is considering separating emojis from system updates, so you can get them faster.
Currently, font files are stored within the system folder, more specifically within the / system / lines folder, and emojis are located in the file named NotoColorEmoji.ttf.
The system folder is read-only, and updating any file inside the folder requires updating the system while the folder is not loaded, so the only way to get new fonts and new Emojis is to wait for the official air update.
The new directory suggests storing them under a separate, readable and writing new folder, allowing the server to update these files.
This means that Google or other manufacturers can send an update to the font file to provide new emojis to users at any time.
The new directory also indicates that this helps other applications read these files, and import the new emojis directly into their system.
This source code has not yet been incorporated into the AOSP Android Open Source Project, so the mod is not final yet.
In the event that within the next few months this source code is incorporated into the Android open source project, we can see this change happen in Android 12.
