    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)
```
    The creation of the table with each tile as a text view and letters and numbers for the first column and row.
    
    Parameters:
    
    mapValues - the map information to process in the creation of the table.
  - showFailureMessage
```
public void showFailureMessage()
```
    Method to show a failure message in case the algorithm is not able to reach the final tile.

    showFailureMessage in interface iAStar
  - drawPath
```
public void drawPath(HeuristicPathTree heuristicPathTree)
```
    Method to control the whole drawing of the path once the algorithm finishes. Also, the user gets the constructor URL for the tree, and gets redirected to the git page in which the actual tree gets drawn using DOT code.
    
    Specified by:
    
    drawPath in interface iAStar
    
    Parameters:
    
    heuristicPathTree - the tree from which all the information is taken.

```
    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

                          int posX)
```
    Update the position and icon of the character once it moves.
    
    Specified by:
    
    moveCharacter in interface iAStar

    posX - Actual X position, then changed to the new one.
  - setColorToField
```
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 iAStar
    
    Parameters:
    
    y - Y coordinate.

  - onStop
```
public void onStop()
```
    Method to make the thread stop once the algorithm finishes.
    
    Overrides:
