I just can't find an up-to-date chart about which mobile devices support which Java Micro Edition version. I'm especially interested in Nokia smartphones and their support for the new JME 3.0 . (I wonder that Sun doesn't seems to provide such information.) Please, provide me some links, if you know any! EDIT: I'm probably mixing things up: MIDP seems to be the mobile Java platform , while J2ME 3.0 is a SDK for it, right? Nokia device specs, including supported JSRs: http://www.forum.nokia.com/devices/ michael aubert You can also have a look at benchmark results as they sometime give a good

<link rel="stylesheet" media="only screen and (max-width:1280px)" href="css/article1280.css"> I'm in the middle of coding my responsive CSS and I realized that the Samsung Galaxy S4 smartphone has a screen resolution of 1080x1920—my 23" monitor is 1920x1080. I've never browsed on this phone (I have an iPhone 3 with a resolution of 320x480 which is what I thought all smartphones were around , somewhere under 800 pixels wide) so I'm a bit perplexed. How am I supposed to create a mobile website for a smartphone with a screen resolution of 1080x1920? Brian P Galaxy S4 reports 360px x 640px to the

I'm writing an Android app that I would like to eventually port to iOS and Windows Mobile (though I know absolutely nothing about them right now). I'd like my app to be able to find other phones within a certain radius (maybe 20-30 feet) that also have the game installed so that the users can interact with others in their current physical space. Is this possible and, if so, how? I plan on the app requiring an internet connection so my first thought was to use GPS like described at iOS Find Other Nearby Devices (GPS locations) , but that would require continually transmitting data to the server

There are a great deal of cross-platform mobile development frameworks around. The major platforms, all mutually incompatible, are: iOS (iPhone, iPad & iPod Touch) Android Blackberry Windows Mobile Windows Phone 7 Symbian MeeGo (merger of Maemo and Moblin) webOS There also exist many different mobile development frameworks that support various arrays of smartphone platforms, including but not limited to: Rhodes ELIPS RAMP Titanium PhoneGap MoSync airplay Bedrock Qt Qt is a great framework for cross platform desktop application development, and takes care of several mobile platforms - Windows

I am eager to know about the architecture of different real-time messenger apps. Are they using any generic protocol/architecture? The WhatsApp Architecture Facebook Bought For $19 Billion explains the architecture involved in design of whatsapp. Here is the general explanation from the link WhatsApp server is almost completely implemented in Erlang. Server systems that do the backend message routing are done in Erlang. Great achievement is that the number of active users is managed with a really small server footprint. Team consensus is that it is largely because of Erlang. Interesting to

I am writing an Android app that returns longitude and latitude, however location holds a Null value. Please see if you can see why, Its been bugging me all day. Code below: public class example extends Activity { public static double latitude; public static double longitude; LocationManager lm; LocationListener ll; Location location; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.questions); lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); ll = new

I use Cordova to develop a smartphone application. In this app, I need to check the internet connection before send request to a server. In order to do that I use the Cordova Connection API, but in the case that the device is connected to a WIFI network with no Internet connection, this API say that we have WIFI connection, is there any way to check if internet is available on the WIFI network ? Send an Dummy ajax request before you send the actual request, If you get and Error Code as '0' it means there is no internet connectivity. $.ajax({ url: 'TestUrl', type: 'GET', success: function (data

I am using html, tag: <input type = "file" /> On android and on many cellulars I have the ability to get the file directly by taking a picture and save it. How can I know (by javascript code) how did I get the picture (direcly by the camera, or by some files that on my cellular)? I did some workarround, and found exif ( http://www.nihilogic.dk/labs/exif/exif.js ), but I didn't succeed using it for images loading dynamically, as the site : http://exif-viewer.com/ Need some source code examples, to understand how exif works on dynamically loaded images. Thanks :) I have found the solution by
