The Android programming structure

Android style or recommendation is not a definite programming rule. However, a good programming practice always includes a set of rules. To code in Android, the code structure follows the Android base structure and hierarchy.

Android typically follows the standards and style of Java. So, the Android programming structure is basically Java structure, which follows the OOP style.

Class formation

Java class formats should be consistent and follow the Javadoc rule; a standard structure should follow this sequence:

1. Copyright information
2. License information
3. Package declaration
4. Library imports
5. Class description and purpose
6. Class definition
7. Global variables
8. Constructor
9. Methods

This is the copyright and license information format:

/*
* Copyright (C) <year> authority
* 
* <License information and other details>
*/

This is the class and method description format:

/*
* <Description>
* <Purpose>
*/

Call hierarchy

Like the coding style, there is no defined call...
