What makes you beginner and what makes you intermediate, let’s have a look.

Things beginners do:
1.No structure in code.
2.Keep pasting same code without making a function
3.Keep themselves away to learn the hard stuff (e.g. Architecture component)
4.They only focus on current task rather than think big, means how it can be used in future.

Things you need to do to become Intermediate.
1. Enhance your thinking by learning new things.
2. If you are not using kotlin, it’s definitely a time. Learning kotlin is very easy and very helpful in your coding.
3. Learn data binding and Architecture component, i prefer MVVM.
4. More Important is format your code in readable form. Make classes and functions to do the same type of work, for eg: create a Util class that has many functions, one of them is to check network connection and return true or false.
