Totally agree! Personal projects help me a lot on getting to know new stuff in Android developement. Sometimes the technologies we use at work are not new or we haven't got the space to apply new stuff and if we want to keep up to date with new trends, the personal projects is the only way we can do it. And just reading about them isn't enough, I need to write code in order to understand how something's supposed to work.
Great article btw!
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
