Installing Android Studio

To set up Android Studio on Windows:

1. Launch the .exe file you just downloaded.
2. 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 exampleC:\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:

1. Launch the .dmg file you just downloaded.
2. Drag and drop Android Studio into the Applications folder.
3. 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:

1. Unpack the downloaded ZIP file into an appropriate location for your applications.
2. 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.

3. 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.
