do you mean creating activities in a course in the Moodle Mobile app?
Teachers cannot create or edit activities in the Mobile app yet, and it isn't in the short term roadmap.
hi Dani Palou

hmm can u tell me the problem for the code, where teacher can create or edit activities in the mobile app?
cz i want to develop this nice mobile app for my majors, which the teacher can create activities on mobile app?
if you want to support it, you'll have to create new WebServices in Moodle since there isn't any to do so. You should look at the code Moodle uses to create the activities, and create a WebService that does the same.
You can see the list of WebServices in Site administration > Plugins > Web Services > API Documentation.
