Android in-depth research and learning courses

 

Android is a Linux-based smartphone operating system developed by Google. It is widely used in 3G mobile phones and netbooks. Currently in the explosive growth phase, HTC (HtC), Motorola, Sony Ericsson, Samsung and many other companies have launched Android-based smart operating systems, and even many netbooks use Android operating systems. Currently, Android is the most popular smart operating system. With the advantages of Linux, the wide application of Android has eclipsed other competitors. Therefore, learning the Android operating system is of great significance.
