```
public android.view.View onCreateView(android.view.LayoutInflater inflater,
                                      android.view.ViewGroup container,
                                      android.os.Bundle savedInstanceState)

    Parameters:
    
    inflater - Layout corresponding to the context.
    
    container - The view group.
    
    savedInstanceState - The bundle containing all the information.
    
    Returns:
    
    the whole view.
  - setFieldColor
```
private void setFieldColor(int y,
                           int x,
                           int color)
```
    Whe receive coordinates and a color, to color a specific tile.
    
    Parameters:
    
    y - Y coordinate.
    
    x - X coordinate.
    
    color - Tile color.
  - loadBoard
```
private void loadBoard()
```
    We load the pre-game board with information like the initial and final tile, we start the tutorial if its the first time executing the app, and finish the method.
  - createTable
```
private void createTable(int[][] mapValues)
```
    Creation of all the tiles as text views, and the first row and column containing letters and numbers.
    
    Parameters:
    
    mapValues - the values corresponding to the whole map of the board.
  - showFailureMessage
```
public void showFailureMessage()
```
    Show failure message in case the final tile is unreachable for any reason.
    
    Specified by:
    
    showFailureMessage in interface iFirstTheBest
  - drawPath
```
public void drawPath(HeuristicPathTree heuristicPathTree)
```
    Drawing of the shortest path followed by the algorithm, just after it has finished. We show a message when the game is finished, and control possible errors if the url to the creation of the tree goes above 1mb, which is the limit of information you can pass in an intent.
    
    Specified by:
    
    drawPath in interface iFirstTheBest
    
    Parameters:
    
    heuristicPathTree - the tree from which the path can be processed and painted.
  - putNodesInfo
```
private void putNodesInfo(android.widget.EditText et)
```
    Method to be able to show the weight of each node in the graphic tree.
    
    Parameters:
    
    et - The node which we are modifying to show the weight.
  - moveCharacter
```
public void moveCharacter(int posY,
                          int posX)
```
    Update the position and icon of the character once it moves.
    
    Specified by:
    
    moveCharacter in interface iFirstTheBest

```
public void setColorToField(int y,
                            int x)
```
    Set color field to a tile once we get its code, so the color will be correct.
    
    Specified by:
    
    setColorToField in interface iFirstTheBest
    
    Parameters:
    
    y - Y coordinate.
    
    x - X coordinate.
  - onStop
```
public void onStop()
```
    Method to make the thread stop once the algorithm finishes.
    
    Overrides:
