Android Studio installation tutorial

1. Pre-installation settings

1. Install JDK

: Http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

Note that you must select a version suitable for your system.

2. Configure java environment variables

Control Panel → system → advanced system settings → "environment variables" under "advanced ":

• Click Create in system variables, enter JAVA_HOME in the variable name, set the variable value to the JDK installation path, and enter "C: \ Program Files \ Java \ jdk1.7.0 _ 21" here.
• In the system variables, click Create variable name and enter CLASSPATH. Fill in the variable value with ".; % JAVA_HOME % \ lib \ tools. jar ". Do not forget the front and middle semicolons.
• Find the Path variable in the system variable, which is built-in to the system and does not need to be created. Double-click Path. Because the original variable value already exists, add "; C: \ Program Files \ Java \ jdk1.7.0 _ 21 \ bin" to the existing variable

Ii. Install Android Studio

Download the android Studio installation file at http://developer.android.com/sdk/installing/studio.html#download. after downloading the file, click next.

If your system is not a win64-bit system, but a 32-bit system, refer to the following solutions:

Answer the 32-bit win7 system question.

Find studio. bat under bin in the installation directory, and use Edit to open studio. bat, lines 25th to 28:

SET JRE=%JDK%IF EXIST "%JRE%\jre" SET JRE=%JDK%\jreSET BITS=IF EXIST "%JRE%\lib\amd64" SET BITS=64

We can see that the number of system bits supported by the software is 64 bits, and my own computer is a 32-bit jre/lib directory with only i386 files.

IF EXIST "%JRE%\lib\amd64" SET BITS=64

Change

IF EXIST "%JRE%\lib\i386" SET BITS=32

For 32-bit XP systems:

Set bits = changed to set bits = 32

64-bit system unchanged

Installation:

It must be jdk. When I first install jre, it is automatically filled with jre, and cannot be used. So I reinstall it later and continue to Next:
