The links that have pages with gif animations are not shown

[rdvg...@gmail.com]

Hi,

Hello,

 

I have an app that shows an ad matrix (buttons). For each ad there is a different link. When a link with a gif animation is activated, only a black screen is displayed, otherwise the page will be displayed without any problem.

My code.

    private void muestraOfertas(Container cnOfertas, Vector vAnuncios) {

        cnOfertas.removeAll();

        cnOfertas.setScrollableY(true);

        Container cntB = new Container();

        int size = Display.getInstance().convertToPixels(15);

        int ancho = Display.getInstance().getDisplayWidth();

        ancho = (int) (ancho - (ancho * 0.03d));

        boolean ciclo = true;

        int c = 2;

        while (ciclo) {

            c++;

            size = (int) (ancho / c);

            int r = ancho % c;

            if (r <= 0 || c >= vAnuncios.size()) {

                ciclo = false;

            }

        };

        vAnuncios = priorizaCampanas(vAnuncios);

        Button bt[];

        bt = new Button[vAnuncios.size()];

        for (int i = 0; i < vAnuncios.size(); i++) {

            Campana1 cM1 = (Campana1) vAnuncios.elementAt(i);

            bt[i] = new Button();

            bt[i].setUIID("Label");

            Image img;

            if (cM1.getRutaLogo().equals("") || cM1.getRutaLogo().equals("null")) {

                img = res.getImage("promo.png").scaled(size, size);

            } else {

                EncodedImage lugar = EncodedImage.createFromImage(Image.createImage(size, size, 0xffcccccc), true);

                img = URLImage.createToStorage(lugar, Integer.toString(cM1.getCampana()), cM1.getRutaLogo());

            }

            bt[i].setIcon(img);

            cntB.addComponent(bt[i]);

            bt[i].addActionListener(new ActionListener() {

                public void actionPerformed(ActionEvent ae) {

                    Display.getInstance().execute(cM1.getEnlace());

                }

            });

        }

        Container cnCentro = new Container(new BoxLayout(BoxLayout.Y_AXIS)).add(cntB);

        cnOfertas.add(BorderLayout.CENTER, cnCentro);

    }

How can i solve this problem?

regards

I have like this problem and I know that depends on the size of the gif image but what the solution for that.

 I need to load and show 1000kb GifImage without seeing black screen  Or anything fishy.

I used same these cn1lib and add this image in src file

and set this code in main.class

  Form hi = new Form("Gif", new BorderLayout());

        try {

            hi.add(CENTER, new ScaleImageLabel(GifImage.decode(getResourceAsStream("/sp2.gif"), 950272)));

        } catch (IOException err) {

            log(err);

        }

        hi.show();

and after tested that on the real android device (8.0.0.158v) the black screen is keeping show before loading gif img like this 

i don't like to keep this black screen and i want to get any way can help to fix this.

some ideas (but i don't know if that possible):

1) load gif image before open app 

2) use native code 

3) get a gif image from theme file 

4) replace black screen to first frame for gif image

5) reduce size of gif image( This can help, but is not a fix to the problem)

Decode can take some time. You can do it on a separate thread so you won't block the EDT. It should work for this particular case although I'm not 100% sure.
