  - appClass
```
protected java.lang.String appClass
```
    The application class to start
  - eglBitsPerPixel
```
protected int eglBitsPerPixel
```
    Sets the desired RGB size for the surfaceview. 16 = RGB565, 24 = RGB888. (default = 24)
  - eglAlphaBits
```
protected int eglAlphaBits
```
    Sets the desired number of Alpha bits for the surfaceview. This affects how the surfaceview is able to display Android views that are located under the surfaceview jME uses to render the scenegraph. 0 = Opaque surfaceview background (fastest) 1->7 = Transparent surfaceview background 8 or higher = Translucent surfaceview background (default = 0)
  - eglDepthBits
```
protected int eglDepthBits
```
    The number of depth bits specifies the precision of the depth buffer. (default = 16)
  - eglSamples
```
protected int eglSamples
```
    Sets the number of samples to use for multisampling.
    Leave 0 (default) to disable multisampling.
    Set to 2 or 4 to enable multisampling.
  - eglStencilBits
```
protected int eglStencilBits
```
    Set the number of stencil bits. (default = 0)
  - frameRate
```
protected int frameRate
```
    Set the desired frame rate. If frameRate higher than 0, the application will be capped at the desired frame rate. (default = -1, no frame rate cap)
  - maxResolutionDimension
```
protected int maxResolutionDimension
```
    Set the maximum resolution for the surfaceview in either the width or height screen direction depending on the screen size. If the surfaceview is rectangular, the longest side (width or height) will have the resolution set to a maximum of maxResolutionDimension. The other direction will be set to a value that maintains the aspect ratio of the surfaceview.
    Any value less than 0 (default = -1) will result in the surfaceview having the same resolution as the view layout (i.e. no max resolution).

```
    Overrides:
    
    onAttach in class android.app.Fragment
  - onCreate
```
public void onCreate(android.os.Bundle savedInstanceState)
```
    This Fragment uses setRetainInstance(true) so the onCreate method will only be called once. During device configuration changes, the instance of this Fragment will be reused in the new Activity. This method should not contain any View related objects. They are created and destroyed by other methods. View related objects should not be reused, but rather created and destroyed along with the Activity.
    
    Overrides:
    
    onCreate in class android.app.Fragment
    
    Parameters:
    
    savedInstanceState - the saved instance state
  - onCreateView
```
public android.view.View onCreateView(android.view.LayoutInflater inflater,
                                      android.view.ViewGroup container,
                                      android.os.Bundle savedInstanceState)
```
    Called by the system to create the View hierarchy associated with this Fragment. For jME, this is a FrameLayout that contains the GLSurfaceView and an overlaying SplashScreen Image (if used). The View that is returned will be placed on the screen within the boundaries of the View borders defined by the Activity's layout parameters for this Fragment. For jME, we also update the application reference to the new view.
    
    Overrides:
    
    onCreateView in class android.app.Fragment
    
    Parameters:
    
    inflater - ignored
    
    container - ignored
    
    savedInstanceState - ignored
    
    Returns:
    
    the new view

```
    Overrides:
    
    onStart in class android.app.Fragment
  - onResume
```
public void onResume()
```
    When the Fragment resumes (i.e. after app resumes or device screen turned back on), call the gainFocus() in the jME application.
    
    Overrides:
    
    onResume in class android.app.Fragment
  - onPause
```
public void onPause()
```
    When the Fragment pauses (i.e. after home button pressed on the device or device screen turned off) , call the loseFocus() in the jME application.

    Called by the Android system each time the Activity is destroyed or recreated. For jME, we clear references to the GLSurfaceView.
    
    Overrides:
    
    onDestroyView in class android.app.Fragment
  - onDestroy
```
public void onDestroy()
```
    Called by the system when the application is being destroyed. In this case, the jME application is actually closed as well. This method is not called during device configuration changes or when the application is put in the background.
