I want to integrate a new application into next cloud. Can I do that? If yes what is the exact process to be followed. Can someone help.
Generate the app from https://apps.nextcloud.com/developer/apps/generate and extract it into apps/
Then take a look at https://github.com/nextcloud/app-tutorial (tutorial and app dev docs are currently reworked). For further questions ask in #nextcloud-dev on irc.freenode.net and be patient until you get your answer (can take seconds up to several hours if everyone is busy)
