Android :: Communicating Between Two Smartphones Without Using Cellular Tower

Aug 14, 2010

Lets say I have 2 mobile phones which are 50 meters away from each other and I would like to send a very small packet of data from mobile-A to mobile-B, without using any communication to cellular tower. To make it simpler, I would like to build an app which implements a Peer to Peer connection for 2 mobiles in the same radius (in the same area). Is this feasible using the technology of smartphones these days?

Android :: Tower Location Information

Aug 19, 2010

I am doing one application in which I am fetching the Cell, location ids of the towers. I am able to get cellid, lacid and networkOperator name. I am using the following code. private GsmCellLocation gsmCellLocation; gsmCellLocation = (GsmCellLocation)cellLocation; cellID = gsmCellLocation.getCid(); lacID = gsmCellLocation. getLac() ; String networkOperatorName = telephonyManager.getNetworkOperatorName(); But I need the location name of the tower, like what we get as Cell info display. How is it possible.

Android :: Communicating With PC - C#

Jan 13, 2010

I want to create an application in Android which communicates with a server application (written in C#, doesn't matter what version of .NET) on the PC via TCP/IP. I was thinking about some kind of RPC like SOAP or XML-RPC. But I want to keep the server application as light and simple as possible. And I think in C# you rely on a Webserver to set up an RPC server. Or maybe is it better to communicate directly via the TcpListener?

Android :: Not Communicating With Computer

I plugged my Hero, via USB cable, into my computer. The charge light is on but my computer is not seeing the device. I have rebooted the phone and the computer and it still won't see the device.

Android :: Communicating Between An App And A Widget

May 10, 2010

Whether its possible for an application and a widget to communicate data to each other directly? Basically I'd need the app to be able to check that the widget is running/visible, and would need the app to send information to the widget. I'm far from actually implementing anything yet, so I'm not really looking for any overly detailed explanations, just if whether or not what I'm looking to achieve is possible.

Android :: Communicating With The PC Via USB Connection

Apr 12, 2010

I'm fairly new to android programming and need some information for a 4th year forensics course project. Basically I am trying to create a suite of tools for live analysis of an android phone. I know how to get the information I need on the phone, but I was wondering if there was a way to communicate that information back to the PC? I want to be able to run a program from a PC, which, when the phone is docked, will allow the user to access information about the phone (ie currently running services/processes, bluetooth/wifi connections, etc). I have a bunch of methods that will run on the phone and get all the information, but I want to be able to call those methods from the PC, execute on the phone, then have the information sent back to the PC to display to the user instead of just displaying it on the phone. This is to leave as small a footprint on the phone as possible.

Android :: Communicating With Servers

Oct 18, 2010

I come from a .Net background and recently x-training to java.

I wanted to develop an Android application that required simple functionality to communicate with a server. For example, functionality such as post a username/score to a website (or service), or request information such as top 10 scores.

What type of communications should I focus on? What is the common technology to use? Does Java have the equivalent of WCF? Or does it have some sort of simple web service? Can web services be secured with authentication?

Ive heard other references to xml-rpc. Should this be something I should look into?

Android :: Automatic Call Forward Based On GPS Or Radio Tower

Oct 21, 2009

I'm a proud owner of a HTC-Hero and I really loves it. Best phone ever.I have managed to find pretty all applications I need but there is one I really missing.When arrive home I am always redirect all incomg calls to my landline and do so by All call forwarding.It happens quite often that I forgets to inactivate this feature when leaving for work and all calls will then be redirected to my home and ofcourse none will answer.I'm looking for an application that identifies my WLAN and then automaticly redirects all calls to my landline and then when signal is lost, remove the redirect. It would also work for me if the application use the radio tower as a reference or via GPS-tracker.

Android :: Communicating Thread With ProgressBar

Nov 14, 2009

Here is my code:

CODE:......

The problem is as follows: progressBar is showing correctly. mHandler obtains the message but only once(for the first time). But I need to make it in loop(as Looper.loop should have worked in this case), so it calls mHandler handleMessage in every loop(but its not happening in this case). The outcome progressBar kept on rotating though the condition in the handleMessage (if(location!=null) )is getting satisfied in the mean time of the active progressbar. How can I make mHandle,sendEmptyMessage to call in each loop so I can check for this (if(location!=null)) condition.

Android :: BroadcastReceiver Communicating With Activity

Feb 26, 2009

Is it possible to update a currently running activity from a BroadcastReceiver? I want to update my activity from a BroadcastReceiver that runs alongside it. When I run my app (from Eclipse), my activity starts. When the BroadcastReceiver is triggered, it currently tries to start the activity (with extras in the bundle...this is the important part), but nothing happens, presumably because the activity is already running. So my question is, how do I get the new information to my Activity (or even just tell the activity that there's new information to get if I stick the information in a database)? This seems like it should be fairly straightforward, but I'm clearly missing something.

Android :: Apostrophe In Communicating With PHP Script?

Jul 14, 2010

I am communicating with PHP web services in Android application. All the requests send from android are encoded with UTF-8 and the php scripts decodes it with utf-8.

But when any request is send with apostrophe ' the decode function of php doesn't seem to work the way it should.

For example, if I send the request as "Today's Horoscope" then its utf-8 encode will be "Today%27s+Horoscope". I tried to decode this with Android and it was successful. But in php it gives the same text after decoding.

The database is MySql. Is this a problem with database or php? I am not sure about it but is there any workaround to this problem?

Android :: Using Socket In Service Communicating With More Activities

Aug 29, 2010

I want to create an application to remote control my PC.

For example: Volume (get actual volume level, increase/decrease/mute volume), TVtime (start/quit tvtime, get actual channel, toggle fulscreen, channel up/down, toggle input source, toggle aspect ratio), Amarok (start/quit amarok, get current song, prev/next song, play/stop/ pause), etc.

The application for the PC is done (in python). The communication protocol used is very simple.

For example: "volume:get_level", "volume:up", "volume:mute", etc. Now I'm working on the android application.

What I have implemented till now is to create an activity, with: - an edittext to enter host:port - a button to connect/disconnect to/from server - the onCreate method creates a new thread for socket communication to send/receive messages to/from PC. - a textview to display information received from PC (eg. volume level) - a button to send command to PC I'm using handler to communicate between the tcpclient thread and the main activity.

It is working... But I want to use more than 1 activity. I want to use different activity for every program controlled. Searching for a solution to transfer the thread's handler to a new activity I have found that it is not possible, and I have to use a service.

So, my question is: how to send message from different activities to the same service, how to send message from service to the actual activity and how can I check in the service which is the actual activity? Because the service is running in the same thread as the activities I suppose that I still have to create a new thread for socket communication. How can I send the data received by the socket to the service?

Android :: Apps - Communicating With Device Plugged In USB Port

Sep 27, 2010

I'm thinking about an Android app (with possibly an accompanying physical device), and i'm trying to figure out whether this is something that's feasible.

1) Let's say I plug my Android to my PC. Would it be possible for an app installed on the PC to communicate with an app running in the cell phone? I just need a very simplistic data exchange, it can even be one-way (just data pushed from the cell phone to the listening app on the PC, whenever the cell phone wants, I don't need any data sent from PC to phone).

When I plug it in, the phone gives me 4 options (charge, disk drive, HTC sync, tethering), which makes me think this is not doable, but still worth the shot.

2) Would it be possible for an app on the PC to talk to an app on the phone through any other way? (Wi-fi, bluetooth, etc). I'm guessing no on wi-fi since neither party has the other's IP (and I want this to kinda just work, not having to input IPs manually all the time).

3) If I make a device that's plugged to the little USB port at the bottom of the phone (and let's say this is a magical device that can do anything, I don't quite care about those details as long as it's doable). Can I have an Android app talk to that device?

4) Any other ideas to make the phone talk to a "device" that I make, or to an app in the PC are more than welcome. Going "through the web" could be an option (although there'd have to be a central server that I own as a middle man, I believe). But i'd prefer if the communication was direct between the two devices.

Android :: Cellular-WiFi Switch

Feb 3, 2010

I'm doing a research on Cellular-WiFi switch and finding any mechanism to handle cellular hand off.As far as i've found,an http request is routed through WiFi network if connected even gprs/cellular connection is present.

My queries are:

1)Does this switch happens automatically ? If yes,which part of framework or code does that?

2)Does the http request drop in such situation due to cellular hand off ? Is there any way to handle such hand off ?

3)Does gprs cellular connection reconnects automatically when WiFi gets disconnected ?

4)Which type of alerts or notifications normally user gets in such situations ?

Yours feedback and inputs will be of great help for me in this activity.

Android :: Custom Ordered Smartphones

May 23, 2010

Its time that we start demanding the ability to "build" our own phones and be able to select both the hardware and software that would be on the phone.Custom orders can be done for personal computers/laptops and even Nike sneakers, so why not smartphones? There are a lot of phones that I like, but there are always a few things about the phones that put me off.Be it a physical keyboard that makes the phone too large, or some a Custom UI put on top of android that makes updates to the latest build few and far in between.I'm sure many of us would pay a little bit more to have a phone made to our exact specifications.Perhaps you like the Droid Incredible but want a physical keyboard, and don't want HTC's Sense on it.How hard would it really be for the manufacture to develop an incredible with a physical keyboard and not add their UI to the phone?

Android :: Why Are Smartphones Horrible Phones?

Oct 3, 2010

Can anyone tell me why smartphones are great for everything except being a phone.I struggled with 2 HTC Evos for about a month.Really poor call quality, earpiece was crap(tinny,blown speaker sound) finally returned it and went back to my Samsung Exclaim for the time being.Wow, what a difference.My old Exclaim is crystal clear, at ALL VOLUMES.Told by radioschack employee to just turn the Evo down when it distorts he was right but then you couldn't hear, especially with any background noise.I will probably try the Samsung Epic in a few weeks. My wife has the Samsung Intercept and compared to the EVO earpiece is 120% better.Why don't they put quality earpieces in smartphones?

Android :: How Smartphones Will Replace Computers?

Jul 28, 2010

Computers and laptops won't exist, only smartphones.We will have desktop and laptop DOCKING stations that we can plug our phones into. Those stations will have no computing or storage or networking capabilities. They will only contain a keyboard, a mouse or touch pad, and a viewing monitor. They will simply receive input from the user and send it to the phone, and display or sound the output.Such docking stations will exist at home, school, work, airports and other public places.

Android : What Smartphones To Target For A Modern B2c App?

May 17, 2010

We want to build a smartphone app which uses geolocation, etc. and target the most important smartphones. Which OS would you support for a b2c application? I found a german statistic here: http://de.statista.com/statistik/daten/studie/150842/umfrage/prognostizierte-marktanteile-der-smartphone-betriebssysteme-in-2013/ which forecasts the smartphone usage for 2013. To summarize it lists the following OS, ordered by priority:

Symbian, Android, Blackberry (RIM), Windows Mobile, iPhone

Would you agree with this priority or should we start with the classical: iPhone/Android combo?
