Easy Budget
Coding Conventions
From the last requirements we did general conclucions and we decided that coding conventions should be in the first rules of android development. As you know when the application has good impression then the customers will be interesting of changing some features inside of this. Every team development would like to use cod without any dificulties. So, for that kind of goal every developer have to follow to coding convention. Reasons for using a coding convention include the following:
- To reduce the effort needed to read and understand source code;
- To enable code reviews to focus on more important issues than arguing over syntax and naming standards.
To enable code quality review tools to focus their reporting mainly on significant issues other than syntax and style preferences.
How do you enforce that all code adheres to your coding conventions?
At the beginning our development we have already decided that the possibilities of code conventions have to follow for the requirements which is shown below:
Class files and Method file
Class names must be wriiten in UpperCamelCase.
SignInActivity, SignInFragment, ImageUploaderService
Naming conventions for icons
Layout files
Layout files should match the name of the Android components that they are intended for but moving the top level component name to the beginning.
Menu files
Similar to layout files, menu files should match the name of the component.
Fields definition and naming
Fields should be defined at the top of the file and they should follow the naming rules listed below.
Use standard brace style
Braces go on the same line as the code before them.
Class member ordering
It is recommendable to use the following order:
- Constants
- Fields
- Constructors
- Override methods and callbacks (public or private)
- Public methods
- Private methods
- Inner classes or interfaces

Specify Context of Use

We believe that every person wants to know where he spent money, how much money he earned. For example, for each student it is interesting to know how much money he spent yesterday at the party. Sports / purchases / bars / transfers - all this can be traced using our application. Even for retired people who have limited knowledge in modern technology, this application can be useful. You are always aware of what is happening with your money and we believe that this is very useful for everyone.
