Android environment Configuration

I like Java and Android.

Write down this article to commemorate yourself.

Not much nonsense:

Configuration steps:

(My development tools are shared with my classmates. If I have resources, I will use them more)

For Java Development, you must first install JDK. After JDK is installed, you must configure environment variables:

1. Download JDK (http://java.sun.com/javase/downloads/index.jsp), the version I downloaded is: jdk-6u14-windows-i586.exe

2. Install jdk-6u14-windows-i586.exe

3. Configure environment variables: Right-click "my computer" --> "advanced" --> "environment variables"

1) create a java_home variable in the system variable. The variable value is: C: \ Program Files \ Java \ jdk1.6.0 _ 24 (based on your installation path)

2) create a classpath variable with the variable value:.; % java_home % \ Lib \ tools. Jar

3) Add the variable value % java_home % \ bin; % java_home % \ JRE \ bin in the PATH variable (no need to create a new variable) (note that the variable values are separated)

4. "Start" --> "run" --> enter "javac" --> "enter". If the command is printed properly, the configuration is successful!

Analysis of supplemental environment variables:

Java_home: JDK installation path

Classpath: the class path loaded by Java. Only the Java commands of the class in classpath can be identified. A "." is added before the path to indicate the current path.

The downloaded file contains three shadow files. If you put them together, you will not take them out again. (* ^__ ^ *)

Anyway, I have something to do in the East and the West. In fact, all methods are acceptable. I have tried several methods on the Internet. The reason is, if you are full, you have nothing to do!

Upload another copy of the instructor's documents. Fortunately, there is no interest in writing this document. I believe that the teacher will not care about it.
