I don't have much experience with the online-based Android app, but from
what I've seen with the Android Viewer app, a change similar to commit
https://git.libreoffice.org/core/+/7374fa59b929bea6792f80a6a819b2a06582722f%5E%21/
might make it work (adding the missing services mentioned in your log
output to the same file).

Seeing what services are mentioned in your debug log (like
"com_sun_star_comp_Writer_MSWorksImportFilter_get_implementation"), I'm
wondering what kind of file exactly you're trying to open. Do you have
the same issue when e.g. trying to open an empty ODT file?

(Maybe somebody else can say more on whether including all services into
liblo-native-code that are required to support all file formats that
LibreOffice supports is fine or would be problematic, e.g. for APK
size,...).
