Find out if resource is used

I am looking for an efficient way to find out if a resource (mostly a drawable) is used in java or in an XML file.

The problem is, that on my current project the drawables are changed often and now I have some drawables, which might never be used.

Is there a tool/way to find those unused drawables without search each filename in the whole project?

Mass email tracking

Most services offered online today that claim to "track" e-mails, do so by embedding images in the emails. My questions are:

1. Is this the only way to do it and if not, what are the other methods?
2. Are any of the methods actually fool-proof?
3. Has anybody had any luck with specific software or even an online group?

Distributed ProjectManagement/Bug Tracking

Now that we have DSCMs, are there any Project Management / Bug Tracking tools that are distributed?

Real time GPS Tracker on JUST HTML / JS and Google Maps to be run on a handphone? Is it possible?

I have read up on GPS Real time tracking and found out several things about it, mostly requiring PHP, zope and a database to store the incoming data. Some other methods uses ajax with relations to PHP.

As regards to my question, is it possible to do so with just html and JS, using markers or anything else to populate the Google Map when you move anywhere in the city? Need some help on this, Thanks!

How does google analytics collect its data?

Yes, I know you have to embed the google analytics javascript into your page.

But how is the collected information submitted to the google analytics server?

For example an AJAX request will not be possible because of the browsers security settings (cross domain scripting).

Maybe someone had already a look at the confusing google javascript code?

Is version control (ie. Subversion) applicable in document tracking?

I am in charge of about 100+ documents (word document, not source code) that needs revision by different people in my department. Currently all the documents are in a shared folder where they will retrieve, revise and save back into the folder.

What I am doing now is looking up the "date modified" in the shared folder, opened up recent modified documents and use the "Track Change" function in MS Word to apply the changes. I find this a bit tedious.

So will it be better and easier if I commit this in a version control database?

Basically I want to keep different version of a file.

• Use Time Machine to save different version (or Shadow copy in Vista)

• There is a difference between text and binary documents when you use version control app. (I didn't know that)

• Diff won't work on binary files

• A notification system (ie email) for revision is great

• Google Docs revision feature.

Update :

I played around with Google Docs revision feature and feel that it is almost right for me. Just a bit annoyed with the too frequent versioning (autosaving).

But what feels right for me doesn't mean it feels right for my dept. Will they be okay with saving all these documents with Google?

How to track a Google Adwords conversion onclick?

Google Adwords offers no code to add to your page to count a conversion if somebody clicks on a link. But as it's Javascript, I am sure there is a way to do this.

Here's the code (unaltered) Google gives you to include in the page, that should count as a conversion (most of the time a thank you page):

<!-- Google Code for Klick Conversion Page -->
<script type="text/javascript">
<!--
var google_conversion_id = 1062751462;
var google_conversion_language = "de";
var google_conversion_format = "1";
var google_conversion_color = "ffffff";
var google_conversion_label = "dKXuCODvugEQ5pnh-gM";
var google_conversion_value = 0;
//-->
</script>
<script type="text/javascript" src="http://www.googleadservices.com/pagead/conversion.js">
</script>
<noscript>
<div style="display:inline;">
<img height="1" width="1" style="border-style:none;" alt="" src="http://www.googleadservices.com/pagead/conversion/1062751462/?label=dKXuCODvugEQ5pnh-gM&amp;guid=ON&amp;script=0"/>
</div>
</noscript>

With other conversion tracking scripts some function has to be executed to count the conversion. Here, just adding the JS-File to your page can be enough to trigger the conversion-tracking, as conversion.js calls a function on load (download it and look at it after running it through a code beatuifier, it's really quite nice work!).

Any idea how to tackle this?

Reading barcodes with android

Hi I am developing an application for the android htc hero. I am looking into ways of using the inbuilt camer to read 2D barcodes and extract the string returned from the barcode. I have only recently begun working with the android sdk but I do have a programming background from working on projects with java. I am curious to know what the best way to read the 2D barcode would be. I have some sample applications that read the barcode but they are all .apk files and have no source or library that i can work with. to give you a better idea of what i am trying to accomplish this site allows the generation of 2d barcodes made up of the data you desire here

Any replies would be greatly appreciated.

Create an Android GPS tracking application

Recently I've taken up android development as a hobby and was looking to develop an application that can find and track a users position using Google Maps.

Once the application has a GPS lock, The application can track their movements by drawing a route using an overlay class.

I've seen similar applications like Mytracks that are open source but they're too complex for me right now.

Ideally i'd love to create an application that looks like this Here

He is my code below without the imports.

What I'm trying to do is create an array of geopoints. Every time the location changes a new geopoint is created. I then try to use a for loop to iterate through each geopoint and draw a path between them.

public class Tracking extends MapActivity implements LocationListener {

LocationManager locman;
LocationListener loclis;
Location Location;
private MapView map;

List<GeoPoint> geoPointsArray = new ArrayList<GeoPoint>();
private MapController controller;
String provider = LocationManager.GPS_PROVIDER;
double lat;
double lon;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.map);
    initMapView();
    initMyLocation();
    locman = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    // locman.requestLocationUpdates(provider,60000, 100,loclis);
    // Location = locman.getLastKnownLocation(provider);

}

/** Find and initialize the map view. */
private void initMapView() {
    map = (MapView) findViewById(R.id.map);
    controller = map.getController();
    map.setSatellite(false);
    map.setBuiltInZoomControls(true);
}

/** Find Current Position on Map. */
private void initMyLocation() {
    final MyLocationOverlay overlay = new MyLocationOverlay(this, map);
    overlay.enableMyLocation();
    overlay.enableCompass(); // does not work in emulator
    overlay.runOnFirstFix(new Runnable() {
        public void run() {
            // Zoom in to current location
            controller.setZoom(24);
            controller.animateTo(overlay.getMyLocation());
        }
    });
    map.getOverlays().add(overlay);
}

@Override
public void onLocationChanged(Location location) {
    if (Location != null) {
        lat = Location.getLatitude();
        lon = Location.getLongitude();
        GeoPoint New_geopoint = new GeoPoint((int) (lat * 1e6),
                (int) (lon * 1e6));
        controller.animateTo(New_geopoint);

    }

}

class MyOverlay extends Overlay {
    public MyOverlay() {
    }

    public void draw(Canvas canvas, MapView mapv, boolean shadow) {
        super.draw(canvas, mapv, shadow);

        Projection projection = map.getProjection();
        Path p = new Path();
        for (int i = 0; i < geoPointsArray.size(); i++) {
            if (i == geoPointsArray.size() - 1) {
                break;
            }
            Point from = new Point();
            Point to = new Point();
            projection.toPixels(geoPointsArray.get(i), from);
            projection.toPixels(geoPointsArray.get(i + 1), to);
            p.moveTo(from.x, from.y);
            p.lineTo(to.x, to.y);
        }
        Paint mPaint = new Paint();
        mPaint.setStyle(Style.STROKE);
        mPaint.setColor(0xFFFF0000);
        mPaint.setAntiAlias(true);
        canvas.drawPath(p, mPaint);
        super.draw(canvas, map, shadow);
    }
}

@Override
public void onProviderDisabled(String provider) {
    // TODO Auto-generated method stub

}

@Override
public void onProviderEnabled(String provider) {
    // TODO Auto-generated method stub

}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
    // TODO Auto-generated method stub

}

@Override
protected boolean isRouteDisplayed() {
    // TODO Auto-generated method stub
    return false;
}
}

The application runs fine without errors but there is no path drawn, the location dot just moves as i move.

Any help would be greatly appreciated Thanks.

How can we track hashtags with the new facebook hashtag implementation

Since Facebook introduced hashtags, I've been interested in finding out more about them. Can someone point me in the direction of possibly tracking the hashtags similar to how twitter allows us access to pull hashtag data via their API. I can count mentions, get usernames, and the tweets. Has Facebook launched anything similar? I can't find any documentation online.

How to capture if a visitor is from a google adwords click

When a user signs up on my site I want to be able to store whether or not they came to my site via an Adwords campaign.

I know google uses javascript to track conversions based on a cookie that is created on the users machine. Is there a way I can check this cookie so I can store the source against the user account?

How does invisible pixel conversion tracking work?

I'm trying to track clicks from our site to an external website. On the external website, I'd like to place some code on their checkout thank-you page, that tells our server that a particular click has resulted in a sale.

How does this tracking code work? Does it need to be a pixel? Do we need to drop a cookie before we send the user to the external website?

Thanks.

Tracking Users coming from a certain source

I'm giving promotions to users who sends us other visitors. This is done on the client side.

I can do this using dynamic GET parameters, e.g. http://www.mysite.com?app_source=user_id or I can do this using the hash, e.g. http://www.mysite.com#app_source,user_id.

Are there any pros and cons for any of these methods?

Track mass email campaigns

Litmus released an email analytics service last month (may 2010).
See here: http://litmusapp.com/email-analytics

They boast a very cool "read rate" tracking: they can track normal reads, Skims, and Glanced/Deleted.

How can they track skims and glanced/deleted? This to me seems impossible :)

They also track forwards and prints. Prints are easy (they include a css @media print query with a bg image).

But forwards? I think this might be a combo between subsequent opens and different IPs/reffering URLs. However, this means that if I open my mail and re-read it from another computer, it counts as a forward. Any ideas on this one?

To summarize: Litmus Email Analytics says they can track email reads, skims, glanced/deleted, prints and forwards. How do they do it (skims, glanced/deleted and forwards)?

Tracking code: This is the code. You create a unique code for each list/campaign combination (so that you can track campaigns..) then you put the following html/css code before the tag of your email message.

<style>@media print{
 #_t { 
    background-image: url('https://a6.emltrk.com/XX0000XX?p');}
 }
 div.OutlookMessageHeader, table.moz-email-headers-table, blockquote #_t {
    background-image:url('https://a6.emltrk.com/XX0000XX?f')
   }
</style>
<div id="_t"></div>
<img src="https://a6.emltrk.com/XX0000XX" style="display:none" width="1" height="1" border="0" />

Test results:

With Gmail, print tracking works. Yahoo! somehow fails. Glances/Deleted actually works, I've tested.

How to implement referral program in mobile Apps for both Android and iPhone
