ArrayIndexOutOfBounds when reading a file Android

Question

I am trying to read a file in my application The content of the file roughly looks like this: 

0 1 
1 0
0 2 
2 0  
...

When I read the file I get an ArrayIndexOutOfBounds Exception This is how I read the file: 

AssetManager amanager ;
    String word = null;

    try {
        amanager= getAssets();
        InputStream inputStream = amanager.open("edges.txt");
        InputStreamReader streamReader = new InputStreamReader(inputStream);
        BufferedReader breader = new BufferedReader(streamReader);
        //word 

        while((word=breader.readLine()) != null){
            String s = breader.readLine();

            String[] words =s.split(" ");

            String sx = words[0];
            String sy = words[1]; // ---LINE 200, THIS IS THE LINE WHERE THE EXCEPTION IS

            System.out.println(sx);
            System.out.println(sy);

        }
        breader.close();
    } catch (IOException e2) {
        // TODO Auto-generated catch block
        e2.printStackTrace();
    }

It reads String sx = words[0];

I have also tried initializing String[] word = new String[500]; but that didn't help.

This is what I get in my LogCat:

readLine() actually reads the line.

You are checking if next line is not null and then skip it and actually split the one after that.

See my changes: 

    while((word=breader.readLine()) != null){


            String[] words =word.split(" ");

            String sx = words[0];
            String sy = words[1]; // --- THIS IS THE LINE WHERE THE EXCEPTION IS

            System.out.println(sx);
            System.out.println(sy);

    }

You're calling breader.readLine() twice with every iteration.

Change this: 

while((word=breader.readLine()) != null){
            String s = breader.readLine();

To: 

while((word=breader.readLine()) != null){
            String s = word;

Additionally, there was whitespace at the end of the file which caused the exception.

This should fix it: 

AssetManager amanager ;
String word = null;

try {
    amanager= getAssets();
    InputStream inputStream = amanager.open("edges.txt");
    InputStreamReader streamReader = new InputStreamReader(inputStream);
    BufferedReader breader = new BufferedReader(streamReader);
    //word 

    while((word=breader.readLine()) != null){
        String s = breader.readLine();
        if (s == null || "".equals(s)) continue;

        String[] words =s.split(" ");

        String sx = words[0];
        String sy = words[1]; // ---LINE 200, THIS IS THE LINE WHERE THE EXCEPTION IS

        System.out.println(sx);
        System.out.println(sy);

    }
    breader.close();
} catch (IOException e2) {
    // TODO Auto-generated catch block
    e2.printStackTrace();
}
