public static float getDensity(android.content.Context context)

Thus on a 160dpi screen this density value will be 1; on a 120 dpi screen it would be .75; etc.
    
    Parameters:
    
    context - The context, which should be used, as an instance of the class Context. The context may not be null
    
    Returns:

  - getStatusBarHeight
```
public static int getStatusBarHeight(android.content.Context context)
```
    Returns the height of the status bar, which is shown at the top of the display (containing the clock, battery indicator, etc.).
    
    Parameters:
    
    context - The context, which should be used, as an instance of the class Context. The context may not be null
    
    Returns:
    
    The height of the status bar in pixels as an Integer value
  - getNavigationBarHeight
```
public static int getNavigationBarHeight(android.content.Context context)
```
    Returns the height of the navigation bar, which is shown at the bottom of the display (containing for example back, home and recent apps soft-keys).
    
    Parameters:
    
    context - The context, which should be used, as an instance of the class Context. The context may not be null
    
    Returns:
