Is there any open source and privacy-respecting Android keyboard for Chinese input? I want to avoid proprietary keyboards such as Gboard and Samsung Keyboard. Unfortunately, the open source Android keyboards that I found only support alphabetic input:
For Chinese input I would like pinyin input for both traditional characters and simplified characters. Handwriting input would be nice to have but it is not essential.
Fcitx5 for Android has decent Chinese, Japanese and Vietnamese. I don't think it has handwriting tho. Otherwise you have Trime, which is Rime for Android but I've never got it to work properly (unlike Rime on Linux which works fine).
I mainly use simplified, so don't pin me on traditional options. I use Florisboard for English.
Trime seems to be traditional first, trimerc is supposed to support both simplified and traditional.
However I cannot get trimerc to work recently, so a switched to Fcitx5, and it works perfectly.
For bopomofo LIME IME seems promising. On its website it says it supports pinyin but I couldn't get it to work for me :(
I am not sure if it supports Chinese input but I use Florisboard myself, a very simple customizeable keyboard.
No, FlorisBoard does not support Chinese input. Source: https://github.com/florisboard/florisboard/issues/149
