android package

Question

I am new to android development.

I have a doubt that while creating an android project (using Eclipse) it asks to specify a package name in project properties which is in the form sample.android but not single name like sample.

What is the reason behind it to follow such naming convention?

Answer 1

just go through these lines--->For example, if an organization in Canada called MySoft creates a package to deal with fractions, naming the package ca.mysoft.fractions distinguishes the fractions package from another similar package created by another company. If a US company named MySoft also creates a fractions package, but names it us.mysoft.fractions, then the classes in these two packages are defined in a unique and separate namespace.

Answer 2

this is just plain programming convetion.

to avoid conflicts with other company, developer's packages.
