Hello,

I am assuming that you have written the OnItemLongClickListener to determine the selected item. To delete the selected item you can call remove method on the ArrayAdaptor if you are using an array or a java.util.List as data source. The remove method takes an argument which is nothing but the item to be removed. After this you will have to call notifyDataSetChanged method of the adapter to reflect the change.

A very decent tutorial on this can be foound here[^].

Hello Kumar,

You can find working examples here. Though not related to binary data transmission, but should get you started.

Below is a sample code for a function which I have used in one of the android application I developed.

Java

/**
 * Helper method to send the request to the MAP
 * @param strUrl The url to be invoked
 * @param params The name value pair list containing the parameters to be sent to MAP
 * @return the JSON response
 */
private JSONObject sendRequest(String strUrl, List<NameValuePair> params) throws Exception
{
    String line = null;
    String strCKVal = null;
    HttpPost httppost = null;
    HttpEntity entity = null;
    HttpClient httpclient = null;
    JSONObject json = null;
    InputStream is = null;
    HttpResponse response = null;
    StringBuilder sb = null;
    BufferedReader reader = null;

    try
    {
        httpclient = new DefaultHttpClient();
        httppost = new HttpPost(strUrl);
        httppost.addHeader("UserAgent","Android");
        if (!StringUtils.isEmpty(_strSesId))
            httppost.addHeader("Cookie", _strSesId);

        httppost.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
        response = httpclient.execute(httppost);
        entity = response.getEntity();
        is = entity.getContent();
        reader = new BufferedReader(new InputStreamReader(is, "UTF-8"), 8);
        sb = new StringBuilder();
        while ((line = reader.readLine()) != null)
            sb.append(line).append("\n");

        CleanupUtils.doClean(reader);
        CleanupUtils.doClean(is);

        if (sb.length() <= 0)
            throw new Exception("Server did not respond ");

        for (Header h : response.getAllHeaders())
        {
            if ("Set-Cookie".equalsIgnoreCase(h.getName()))
            {
                strCKVal = h.getValue();
                break;
            }
        }

         json = new JSONObject(sb.toString());
        _strSesId = strCKVal;
        return json;
    }
    finally
    {
        CleanupUtils.doClean(reader);
        CleanupUtils.doClean(is);
        if (line != null) line = null;
        if (strCKVal != null) strCKVal = null;
        if (entity != null) entity = null;
        if (httppost != null) httppost = null;
        if (reader != null) reader = null;
        if (is != null) is = null;
        if (response != null) response = null;
        CleanupUtils.doClean(is);
        if (sb  != null)
        {
            sb.delete(0, sb.length());
            sb = null;
        }
        if (httpclient != null) httpclient = null;
    }

PIC-32 UART Receives Only Ten Bytes Then No More

I have an external source that sends lots of bytes (more than a hundred) to the Uart of a PIC-32.

Problem 1: The PIC-32 Uart does not produce the bytes he is sent; he scrambles the bits

Problem 2: After giving me ten bad bytes, he stops producing anything.

Has anyone ever seen this problem before ?

Did you solve it ?

Android renderscript.

Hey I wanted to find out if it is necessary to use renderscript for image processing apps on android. I'am coding an android panoramic view creator for creating 360 degree high quality panoramas but I had written the initial code in C++, but for android I have to use java and I have read about android phones not being so powerful because of their use of the virtual machine. So I was thinking of using renderscript for the android apps, is it necessary or just normal java code can do for such a task as panorama creation?

The <mandroidi18n> entry goes into the .csproj, not AndroidManifest.xml.

This can also be set in the IDE.

In MonoDevelop:

Click Project > Project Name Options.
In the left-hand tree, select Build > Mono for Android Build.
In the right-hand pane, select the Advanced tab.
In the Internationalization section, click the checkbox next to west.
Note: Make sure you're changing options for your Release build, not the Debug build.

Within Visual Studio:

Click Project > Project Name Properties.
In the Application tab, look in the Application properties > Additional supported encodings section (it's on the right).
Click the checkbox next to West.

I don't think you will be able to use MessageBox on Mono Android. MessageBox class is part of System.Windows.Forms package and is not available on Mono for Android. Instead please have a look at AlertDialog Sample[^].

Which tablet platform is most secure?

Hi,

Since more and more PC users moves they activities to the mobile devices, such as tablets and smartphones( http://www.npd.com/wps/portal/npd/us/news/press-releases/37-percent-of-pc-users-migrate-activities-to-mobile-devices-according-to-the-npd-group/[^] )
the one of the biggest questions is the platform security. PC's are guarded by well established anti-fishing/virus programs, but mobile systems very frequently do not have'em at all.
Which platform is most secure right now, and what are perspectives?

Thanks.

All platforms are secure, but it is up to you the user to ensure you install software protection such as anti-virus etc. It only becomes insecure when you start accessing the internet.

The issues remains the same. Whichever device you choose you will need to ensure it has adequate security software installed.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
