(This is the simplest set of Android software development tutorials I collected on the Internet. In the form of PPT, it starts from helloworld and goes deeper and deeper. It is most suitable for friends who have no experience in mobile platform development. If you only know some simple C language, I think you can understand it. If you need a higher level of Android development or have experience in Android software development, you don't need to download it. I will provide a higher level of teaching materials in the future
