Installing Android Studio

摘要: The Android SDK Manager separates the SDK tools, platforms, and other components into packages for easy access and management. You can also customize which sites the SDK Manager checks for new or updated SDK packages and add-on tools. For example, you can configure the SDK Manager to automaticall...

Android Studio provides everything you need to start developing apps for Android, including the Android Studio IDE and the Android SDK tools.

If you didn't download Android Studio, go download Android Studio now, or switch to thestand-alone SDK Tools install instructions.

Before you set up Android Studio, be sure you have installed JDK 6 or higher (the JRE alone is not sufficient)—JDK 7 is required when developing for Android 5.0 and higher. To check if you have JDK installed (and which version), open a terminal and type

javac -version

. If the JDK is not available or the version is lower than 6,go download JDK.

To set up Android Studio on Windows:

Launch the

.exe

file you just downloaded.

Follow the setup wizard to install Android Studio and any necessary SDK tools.
On some Windows systems, the launcher script does not find where Java is installed. If you encounter this problem, you need to set an environment variable indicating the correct location.
Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable

JAVA_HOME

that points to your JDK folder, for example

C:\Program Files\Java\jdk1.7.0_21

.

The individual tools and other SDK packages are saved outside the Android Studio application directory. If you need to access the tools directly, use a terminal to navigate to the location where they are installed. For example:

\Users\<user>\sdk\

To set up Android Studio on Mac OSX:

Launch the

.dmg

file you just downloaded.

Drag and drop Android Studio into the Applications folder.

Open Android Studio and follow the setup wizard to install any necessary SDK tools.
Depending on your security settings, when you attempt to open Android Studio, you might see a warning that says the package is damaged and should be moved to the trash. If this happens, go to System Preferences > Security & Privacy and under Allow applications downloaded from, select Anywhere. Then open Android Studio again.

If you need use the Android SDK tools from a command line, you can access them at:

/Users/<user>/Library/Android/sdk/

To set up Android Studio on Linux:

Unpack the downloaded ZIP file into an appropriate location for your applications.

To launch Android Studio, navigate to the

android-studio/bin/

directory in a terminal and execute

studio.sh

.
You may want to add

android-studio/bin/

to your PATH environmental variable so that you can start Android Studio from any directory.

If the SDK is not already installed, follow the setup wizard to install the SDK and any necessary SDK tools.
Note: You may also need to install the ia32-libs, lib32ncurses5-dev, and lib32stdc++6 packages. These packages are required to support 32-bit apps on a 64-bit machine.

Android Studio is now ready and loaded with the Android developer tools, but there are still a couple packages you should add to make your Android SDK complete.
