Android development environment built under Windows system

"Tools are good, its prerequisite." To learn Android well, it's a good start to build an Android development environment.

There are 4 major steps in the Android development environment under the Windows system. respectively:

Installation of 1.JDK

Installation of 2.eclipse

Installation of the 3.Android SDK

4.Android ADT Plug-in installation

--------------------------------------------------------------------------------------------------------------- -----------------------------

Installation of 1.JDK

1.1 Installing the JDK

There is no difference between installing a normal application.

1.2 Configuring environment variables

1) Create a new system environment variable java_home, which is the installation path of the JDK on your computer. Once created, you can use%java_home% as the unified reference path.

2) Modify the existing system environment variable PATH, the value is:;%java_home%\bin;%java_home%\jre\bin.

3) Create a new system environment variable CLASSPATHwith a value of:.; %java_home%\lib;%java_home%\lib\tools.jar (Note that there is a dot ahead).

1.3 Verifying that the JDK is installed successfully

Run the following command from CMD:

1) Java-version will appear with Java version information.

2) Javac will appear with instructions on the Javac command.

If you execute the above two commands, the console has a corresponding expected output, and the JDK installation configuration is successful. If you execute the javac command prompt "Javac is not an internal command or external command, or a program or batch file that can be run," stating that the JDK is not installed correctly, you should try to reinstall the JDK again, paying particular attention to the configuration of the environment variables.

Installation of 2.eclipse

Eclipse is free to install software, that is to say, we download the Eclipse compact package, directly decompression can be used.

After decompression, the author appeared unable to download the JNI shared library problem:Failed to load the JNI library. The eclipse is found to be 32bit, and the JDK is 64bit, which is incompatible.

Workaround: The two digits are the same, either 32-bit or 64-bit.

Installation of the 3.Android SDK

In the Android SDK installation directory, double-click "SDK Manager.exe" to open the Android SDK Manager,android SDK Manage is responsible for downloading or updating different versions of the SDK package, we see the default installed Android SDK The manager installs only one version of SDK tools.

Open the Android SDK Manager, which will get an installable version of the SDK, but there are walls in the country, sometimes there will be a failure to obtain. "At the end of the article will be provided"
