java - What is the best practice for putting classes under package names in Android -

android studio 0.8.11

hello,

i have completed test on android build app takes live news feed, , display them. however, instructor critical set classes under 1 package.

i wondering best practice packaging classes. particular test have next classes under bundle name:

com.viewsys.ncon

my classes these:

dbhelper <-- database creating , ugprading detailactivity <-- activity add together ncondetailfragment nconcontract <-- properties of database schema columns, table name ncondetailfragment <-- detail fragment nconlistfragment <-- list fragment nconviewpager <-- view pager jsonnewsfeed <-- class downloads , parses json format mainactivity <-- main activity newsfeed <-- class of properties getters/setters news feed newsfeeddb <-- simple array list store object sqlite3 db splashactivity <-- activity add together splashfragment , nconlistfragment splashfragment <-- splash fragment utilities <-- simple utility functions

many suggestions,

first separate model (classes holding data) , view (everything display) , create subpackages different types of classes.

for example:

com.viewsys.ncon

utilities

com.viewsys.ncon.model

nconcontract jsonnewsfeed newsfeed

com.viewsys.ncon.model.db

dbhelper newsfeeddb

com.viewsys.ncon.view

nconviewpager

com.viewsys.ncon.view.activities

detailactivity mainactivity splashactivity

com.viewsys.ncon.view.fragments

ncondetailfragment nconlistfragment splashfragment

you should seek minimize bundle dependency cycling. means 1 bundle can depend on other (or multiple other) bundle , utilize classes required bundle should minimize dependency first package. dependeny calls should go 1 direction.
