I have built an App and have deployed on iOS to date. I need to build the same functionality on Android and believe me I have extensively researched various courses, tutorials, etc.. and have found Mitch's content to be the best I can find. Mitch is clear, and his examples are relevant. Although I can find various tutorials focusing on a single aspect of my App, Mitch provides tutorials which brings all these things together, so they work much better, and the code is easier to maintain. In fact I signed up for some of the paid tutorials and I wasn't disappointed and can say it was a good investment, and would recommend.
