According to foreign media reports, Emoji Emoji has become an indispensable part of people's daily informal expression. These tiny graphic assets add emotion, intention and character to simple words. The frequent addition of new emoticons to the Unicode standard is proof of their popularity. Whenever Unicode gets new emoticons, people usually have to wait for the operating system to upgrade to support emoticons before they can really become part of our network language.Google seems ready to make this easier, as some submissions indicate it is trying to separate the new emoticons from Android updates.
At present, all fonts in XD / system are in Android storage system. In particular, emoticons exist in names called NotoColorEmoji.ttf File. The system partition is read-only, and any file in the partition needs to be updated when the partition is not mounted. So the only way to get new fonts and emoticons is to wait for the official OTA update or install it unofficially through root.
However, a new submission has now been found on the Android open source project (AOSP) Gerrit, which seems to be separating font files from where they need to be upgraded. The description of the submission is as follows:
Add / data / fonts / files directory:
The updated font file will be stored in / data / fonts / files and all applications will read the font file to get the drawing text. Therefore, / data / fonts / files must be readable by the application and only by system_ Server (and init) write.
Set the / data / fonts directory to get updated system fonts:
– / data / fonts / files the updated font files are located in this directory. Any application can read files in this directory. Only system_ Server can write font files to this directory.
The site does point out that the change is still in its early stages and may not even be implemented in the next Android version. Of course, this will not affect the Android system as a whole.
