At first, I learned through Baidu that the development environment of Android is a combination of ECLIPSE+ADT+SDK, and the need for something to go down, the process will take more time. Later because the classmate has the Android studio installs the package and the SDK file, so I gave up the ECLIPSE+ADT+SDK combination, chose installs the Android studio, simultaneously copied the classmate's SDK file directly. With the help of classmates, the installation of Android studio did not encounter too much problem, because the installation requires a Java environment, so before installing Android studio, you should first configure the Java environment.
Because it is the first time to use Android Studio, so for some of the software operation is not understood, write HelloWorld is also in the stumble, the specific operation process is not detailed. The process of creating is simple, create a new project, and lazy people will be next. Because of the lack of understanding of the Java language, so I directly use a ready-made text box, the contents of the text box can be edited before running, or you can run the HelloWorld program on the Android virtual machine before editing, the final completion diagram is as follows.
