Aksing the framebuffer width and hight gives strange Values

[dandee]

Hello,

searching the forum gives me no hint about my problem. Maybe you know somethin about that.

I initialize my frame buffer due to some samples. At the moment I am working on some tests about overlays. The overlays should fit its size relative to the frame buffer width and hight.

Am I right if I assume that the framebuffer.getHeight() and framebuffer.getWidth() should be the same as my screensize on my device?

Everytime I ask the framebuffer  for its dimensions I get something like (nearly the same on my sgs2 and the emulator)

12-19 22:27:04.780: INFO/System.out(14500): AUFLÖSUNG HEIGHT!: 320
12-19 22:27:04.780: INFO/System.out(14500): AUFLÖSUNG WIDTH!: 533

The Initialisation of my mglview:

mGLView = new GLSurfaceView(getApplication());

mGLView.setEGLConfigChooser(new GLSurfaceView.EGLConfigChooser() {
public EGLConfig chooseConfig(EGL10 egl, EGLDisplay display) {
// Ensure that we get a 16bit framebuffer. Otherwise, we'll fall
// back to Pixelflinger on some device (read: Samsung I7500)
int[] attributes = new int[] { EGL10.EGL_DEPTH_SIZE, 16, EGL10.EGL_NONE };
EGLConfig[] configs = new EGLConfig[1];
int[] result = new int[1];
egl.eglChooseConfig(display, attributes, configs, 1, result);
return configs[0];

}

My Renderer:

    //----------------DER RENDERER----- EMBD KLASSE----------
    class GameRenderer implements GLSurfaceView.Renderer {

    // Faramecounter
    private int fps = 0;
    //private int lfps = 0;
    private long fpsTime = System.currentTimeMillis();
   
    private boolean stop = false;
   
    //Voreinstellungen für den Renderer
    public GameRenderer() {
Config.maxPolysVisible = 500;
Config.farPlane = 3000;
Config.glTransparencyMul = 0.1f;
Config.glTransparencyOffset = 0.1f;
Config.useVBO=true;

Texture.defaultToMipmapping(true);
Texture.defaultTo4bpp(true);
}
    public void stop() {
stop = true;
}
   
@Override
public void onDrawFrame(GL10 arg0) {

try {
if (!stop) {

//Block für das Gesamtrendering
fb.clear(fbBackgroundColor);


if (GameWorldVisible) {
GameWorld.renderScene(fb);
GameWorld.draw(fb);
}
if (EnvBoxWorldVisible) {
EnvBoxWorld.renderScene(fb);
EnvBoxWorld.draw(fb);
}
if (OverlayWorldVisible) {
OverlayWorld.renderScene(fb);
OverlayWorld.draw(fb);
}
if (SystemMessageWorldVisible) {
SystemMessageWorld.renderScene(fb);
SystemMessageWorld.draw(fb);
}
checkConnection();

//WorldModifier.checkAndExecute();


fb.display();
//Ende Block für das Gesamtrendering
} else {
if (fb != null) {
fb.dispose();
fb = null;
}
}
} catch (Exception e) {
e.printStackTrace();
Logger.log("Drawing thread terminated!", Logger.MESSAGE);
}

}

@Override
public void onSurfaceChanged(GL10 gl, int width, int height) {
if (fb != null) {
fb.dispose();
}
// Analyse der Displaygröße und übergabe an den Framebuffer
fb = new FrameBuffer (gl, width, height);
//fb = new FrameBuffer (gl, 800, 400);
}

I think setting the framebuffer size by hand is not the soultion....

Do you have any ideas?

Kind regards

That depends on your AndroidManifest.xml and the choosen target platform. Try to add

Code Select Expand


  <supports-screens
          android:largeScreens="true"
          android:normalScreens="true"
          android:smallScreens="true"
          android:anyDensity="true" />


to it to see if that helps.

Thank you for your help,

I think that did the job. At my Manifest I removed android:resizeable="true" . After that the resolution is correct.

Many thanks!!!
