Android (Android) is a free and open source operating system based on Linux. Primarily used on mobile devices such as smartphones and tablets. I have posted an IOS development tutorial before, an operating system developed by Apple.
In addition, the Android operating system is more popular among the users. Before Android started, it had high playability due to flashing and so on. With the upgrade of Android by Google, the Android system is also optimized by various mobile phone manufacturers and becomes more and more popular. smooth.
Recently, I have seen a lot of Android novices asking about Android learning routes, learning methods, how to get started, and what specific knowledge do you need to master to learn Android development? The following editor will give you a summary.
What knowledge do I need to learn Android?
First of all, for those who have no learning direction and lack of systematic knowledge, I will share with you the learning route I have organized for several years as a reference. Those who do not know how to learn can directly follow my learning route one by one. Go to study, those who do not have systematic knowledge can refer to the way I arrange the route, in short, I hope to help you!
