Android Studio Installation

first, the Preparation tool:

1. Configuring the PC Java JDK Environment

JDK can be downloaded to the official website, download the appropriate JDK according to the configuration of the computer you need to install

Http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

I choose here: Jdk-8u25-windows-x64.exe

Note the distinction:

Java SE Development Kit 8U25
Java SE Development Kit 8u25 Demos and Samples Downloads
JavaFX Demos and Samples Downloads

The first Java SE Development package
Second Java SE development package + example
A third JavaFX development kit and example

The first is the one that must be configured for the Java development environment

II. installation of JDK steps

1. Install JDK,JRE, select the installation directory

There are two installation prompts during installation. The first time is to install the JDK, and the second is to install the JRE. It is recommended that all two are installed in a different folder in the same Java folder. (cannot be installed in the Java folder root directory, JDK and JRE installed in the same folder will be error).

(1) Double-click Jdk-8u25-windows-x64.exe to install.

(2) Click "Next" to continue.

3) Select the installation path and click Next.

The default is on the C drive. I chose the D-plate here. Path is: D:\Java\jdk1.8.0_25\

(4) Wait for the installation to finish. Select the path to the JRE installation and click Next.

C drive is selected by default.

Wait for the installation to complete.

(5) Installation of the JRE

(6) I choose the D-plate here. When you select the change, first create a folder in the hard disk. Because it does not give new at the time of the selection. I am here to build a: Jre1.8.0_25 folder.

(7) When the installation is complete, click Close.

2. Configuring the System environment

Configure environment variables: Right-click "My Computer"-"advanced"-"Environment variables".

(1) Java_home environment variables.
Role: It points to the JDK's installation directory, and Eclipse/netbeans/tomcat software is to find and use the installed JDK by searching for java_home variables.
Configuration method: In the system variable click New, variable name fill java_home, variable value to fill the JDK installation path. (Fill in according to your own installation path)

Java_home:d:\java\jdk1.8.0_25

(2) Classpath environment variables.

Role: is to specify the class search path, to use the already written classes, the premise is to be able to find them, the JVM is through the classpth to find the class. We need to set the Dt.jar and Tools.jar in the Lib subdirectory of the JDK installation directory to classpath, of course, the current directory "." must also be added to the variable.
Configuration method:
Create a new classpath variable with a variable value of:.; %java_home%\lib;%java_home%\lib\tools.jar. Classpath variable name, can be uppercase or lowercase. Be careful not to forget the front dot and the middle semicolon. And a semicolon and a comma to enter in the English state.

CLASSPATH:.; %java_home%\lib;%java_home%\lib\dt.jar;%java_home%\lib\tools.jar;

(3) PATH environment variable

Function: Specifies the command search path, executes the command under the I command line as Javac compiles the Java program, it looks in the path specified by the path variable to see if the appropriate command program can be found. We need to add the bin directory in the JDK installation directory to the existing path variable, and the bin directory contains the frequently used executables such as Javac/java/javadoc wait, and after setting the path variable, you can execute the Javac/java tool in any directory.

Find the path variable in the system variable, which is the system's own, not new. Double-click Path, because the original variable value already exists, it should be added ";%java_home%\bin;%java_home%\jre\bin" after the existing variable. Note the preceding semicolon.

Path:;%java_home%\bin;%java_home%\jre\bin

Then click OK to finish.

Third, the test environment.

Verify that the configuration runs CMD successfully, enter Java,javac separately, java-version (there are spaces between Java and-version).

Environment variables:
Java_home:d:\java\jdk1.8.0_25
CLASSPATH:.; %java_home%\lib;%java_home%\lib\dt.jar;%java_home%\lib\tools.jar;
Path:;%java_home%\bin;%java_home%\jre\bin

Test:
Java,javac,java–version

Second, install Android Studio.

1. Double-click the installation file of Android Studio to enter the installation interface:

2. Select the installed plug-in.

The first one is the Android Studio main program, which must be selected.

The second one is the Android SDK, which installs the Android5.0 version of the SDK, which is also hooked up.

The third and fourth are the accelerators for virtual machines and virtual machines, and if you want to use a virtual machine debugger on your computer, tick it.

Click Next next when you are done.

3. Select the installation directory for Android studio and SDK

Choose the disk you are accustomed to install the software can be, C drive D disk does not matter, the following SDK path back to configure the use of.

4. Set the maximum memory that can be used by the virtual machine hardware accelerator

If your computer configuration is good, the default setting of 2G, if the configuration comparison, choose 1G is similar, otherwise too big will affect you to run other software.

5, the next step, will enter the automatic installation mode.

If nothing happens, after a short period of time you will see the following interface, also indicates that the installation was successful. Start the software.

6. After opening Android studio, enter the relevant configuration interface.

This is the profile for importing Android studio, if it is the first time, select the last item: Do not import the configuration file, then click OK.

7, the previous step is completed, will enter the following page, which is the program to check the SDK update situation.

Due to our national conditions, if your computer can not FQ or not configure the hosts, this page will be stuck to when who also said bad.

We recommend that you do the following:

(1) in the Android Studio installation directory under the Bin directory, locate the idea.properties file;

(2) Append disable.android.first.run=true at the end of the document.

(3) "Skip this step." If you need to update the SDK later, click on the last red link in the "Second, resource download" above to download the required installation package for offline configuration.
