You Can t write JSON file while in assets  as already described assets are read-only  But you can copy assets  json file anything else in assets   to local storage of mobile and then edit write read  from local storage  More storage options like shared Preference for small data  and sqlite database for large data  are available

You cannot write data s to asset Raw folder  since it is packed  apk  and not expandable in size   If your application need to download dependency files from server  you can go for APK Expansion Files provided by android  http   developer android com guide market expansion-files html
