This app is made with a purpose to help newbies understand core concepts of Android Development. There are very limited and not so clear resources available out there, Hence I've decided to fix it.

I am currently rewritting the whole codebase in a more cleaner way, mvc architecture pattern and with TDD approach. This is work in progress, please checkout the branch "cleanCode1" for the same.

• Introduce modules in your app.

• All the names in the code should be clear and meaningful.
• Do not add unnecessary and redundant comments in the code.
• The comment should be used to clarify the respective piece of code.

• The files should be consistent and not very long.
• Files should have headings to explain the purpose of the file.

• Generally, all the classes should have separate files.
• Classes and Functions should be too the point.
