      protected 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).

    • audioRendererType

      protected String audioRendererType
      Sets the type of Audio Renderer to be used.

      Android MediaPlayer / SoundPool can be used on all supported Android platform versions (2.2+)

      Only use ANDROID_ static strings found in AppSettings

    • joystickEventsEnabled

    • splashPicID

      protected int splashPicID
      Splash Screen picture Resource ID. If a Splash Screen is desired, set splashPicID to the value of the Resource ID (i.e. R.drawable.picname). If splashPicID = 0, then no splash screen will be displayed.

      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:
