Android Studio+Kotlin Project Feature Addon

Just add a feature Please read my explanation: This is an diary app then the important feature of this app is *emotion recognition*. So the database has only 2 class: user and diary But diary table need to develop also as location, diary content and emotion result I haven’t added yet. class: imagehelper, DetailActivity layout: registery_fragment, detail_activity these four is not in use as for me testing purpose For emotion recognition if can use audio is better if can't totally then only use text, but give me reason why not able to use audio As my objective is to analyse emotion through audio This ideas my instructor suggested I don't have much reference other sample for the app. I have only this sample: [login to view URL] I tried to use microsoft azure text and face api to do but failed. Instructor allowed me to do face recognition, if I am not able to do text and audio. *Diary App Features* create, retrieve, update, delete - user (done register; login, modify n delete *not done*) (can refer to diary CRUD) - diary (*done* CRUD) - emotion recognition (either in text or image *not done*)
