Hello everyone, I want to become an experienced android developer, I read the head first android book, some knowledge was deposited, I can make simple applications without problems, I know some important topics (activity life cycle, fragments, intents, implicit intents, listeners and many more small topics) , I understand the development environment, who cares, I write in java. So, the question arose of how to move on, I got to a dead end, tried to start a small project, read the docks, but there is little knowledge from this, and it also makes sense. Recently I learned that there are some design patterns, such as mvp and a lot of things I don’t know yet. Can you please write how I should proceed further, what to read, what to learn, and so on, some topics that an android developer should know.
*Thanks in advance.*
