Question

I connect a ıp cam(jpeg), and show this image, and ı repeat continually, After a while my app error this...

my codes:

public void parse(InputStream is){
        try {
            if (!type.isMjpegStream()) {
                CameraManagerScreen.ActiveCam.setConnected(true);
                setImage(is);
                is.close();
                System.gc();
                if(!mjpeghttp.isCanceled())
                        go();
            } 
        } catch (Exception e) {
        }
    }

and my connection is:

protected void connect() {
    InputStream is = null;

    try {



        HttpParams httpParameters = new BasicHttpParams();
        // Set the timeout in milliseconds until a connection is
        // established.
        int timeoutConnection = 20000;
        HttpConnectionParams.setConnectionTimeout(httpParameters,
                timeoutConnection);
        // Set the default socket timeout (SO_TIMEOUT)
        // in milliseconds which is the timeout for waiting for data.
        int timeoutSocket = 20000;
        HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

        client = new DefaultHttpClient(httpParameters);

        method = new HttpGet(getUrl());
        System.out.println("Baglanıyor:  " + method.getURI().toString());
        method.addHeader("Authorization", getBase64Encode());

        res = client.execute(method);
        System.out.println("RESPONSE: "
                + res.getStatusLine().getStatusCode());

        is = res.getEntity().getContent();

        if (!cancel) {
            onReturn(res.getStatusLine().getStatusCode(), is);

        }

    } catch (Exception e) {
        System.out.println(e.getMessage());

        try {

            cancel = true;

            Thread.sleep(60);

        } catch (Exception ie) {
        }
        onError(new Exception("0"));
    }
}
