To set up Android Studio on Windows

http://developer.android.com/sdk/installing/index.html?pkg=studio


To download Android Studio on Windows:
http://developer.android.com/sdk/index.html

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\

Multi-Dimensional Arrays



The arrays you have been using so far have only held one column of data. But you can set up an array to hold more than one column. These are called multi-dimensional arrays. As an example, think of a spreadsheet with rows and columns. If you have 6 rows and 5 columns then your spreadsheet can hold 30 numbers. It might look like this:
A representation of a 2-dimensional array
A multi dimensional array is one that can hold all the values above. You set them up like this:
int[ ][ ] aryNumbers = new int[6][5];

Arrays

Java Arrays

A programming concept you just have to get used to if you're to code effectively is the array. In this section, you'll learn what arrays are, and how to use them.

What is an Array?

So far, you have been working with variables that hold only one value. The integer variables you have set up have held only one number, and the string variables just one long string of text. An array is a way to hold more than one value at a time. It's like a list of items. Think of an array as the columns in a spreadsheet. You can have a spreadsheet with only one column, or lots of columns. The data held in a single-list array might look like this:
A representation of an array
Like a spreadsheet, arrays have a position number for each row. The positions in an array start at 0 and go up sequentially. Each position in the array can then hold a value. In the image above array position 0 is holding a value of 10, array position 1 is holding a value of 14, position 2 has a value of 36, and so on.
To set up an array of number like that in the image above, you have to tell Java what kind of data is going in to your array (integers, strings, boolean values, etc). You then need to say how many positions the array has.
