Based on my experience trying for several weeks,
https://github.com/ayatakesi/termux-emacs
https://qiita.com/ayatakesi/items/be1868d2f394d39f1e76

in addition to specify sharedUserId, it requires to change the Java
classpath(directory structure of java sourse files and classpath
references in sourse files).

The repository's README and article are written in Japanese, but I
believe it can be understood in English using Google Translate
(At least, its quality is  equivalent to the English text I would write.

Changes I made are all contained in the patch file.

In my case, it requires some changes to the source code in order to specify
how the soft keyboard should be displayed.
