Android :: Android (Java) Simple Send And Receive With Server

Jun 11, 2009

I'm writing an Android App and I'm looking for the fastest (In terms of setup) way for me to send data to a server and receive information back on request. We're talking basic stuff. I have a log file which tells me how a user is using my application (In beta, I wouldn't runin a user experience by constantly logging usually) and I want to communicate that to my server (That I haven't setup).

I don't need security, I don't need high throughput or concurrent connections (I have 3 phones to play with) but I do need to set it up fast! I remember back in the day that setting up XAMPP was particularly brainless, then maybe I could use PHP to send the file from the phone to the Server? The Server would ideally be able to respond to a GET which would allow me to send back some SQL statements which ultimately affect the UI. (It's meant to adapt the presented options depending on those most commonly used).

So there you have it, I used PHP about 4 years ago and will go down that route if it's the best but if there's some kind of new fangled port open closing binary streaming singing and dancing method that has superseeded that option I would love to know. This tutorial seems useful but I don't really need object serialization, just text files back and forth, compressed naturally. Android comes with the Apache HTTP Client 4.0 built in as well as java.net.URL and java.net.HttpUrlConnection, I'd rather not add too much bult to my App with third party libraries.

Android :: Simple Shape Recognition Libraries For Java

Mar 16, 2010

I am working on a on-screen keyboard for Android, and I need to recognize starting points, turning points and end points of lines drawn by the user on the keyboard. A simple straightening function would be nice, as it is difficult to draw a perfectly straight line even with a stylus, not to mention finger-only touchscreens today.What I am trying to write is something like Swype. Any good libraries that I can use or make reference to?

Android :: Develop Using Libraries In Simple Java Project - Without Using Dalvik And Such

Oct 9, 2010

As I am very pissed off of using the emulator to develop any Java class, I thought of setting up a project in Eclipse and instead of the usual JRE I linked to the Android.jar (version 2.1) that usually the Android projects link to. I don't mean to use this to develop Layouts or other specific platform things, I was just trying to create a class that uses HttpClient.

It miserably crashes like this.

CODE:.............

I mean I'd like to develop libraries (and test them) so that when I go to the emulator I don't have to deal with them. Is there a good way to do this? This seems not to work for some reason.

Android :: Use HTTP Post Method Or Simple Java Socket Program

Mar 20, 2010

Could someone please suggest me a good/efficient way to communicate with the server. I could think of two options 1) Use http post methods to send data to a php script at the server which would later call the google api's written in another java program (jar)or use php to use google api's (if its possible) to find nearby restaurants and send the list back to client. 2) Use simple java socket programming. The server has a jar file that supports multi threading and it does the job of finding restaurants and sending the list.

Android :: Using C2DM To Receive Notification From Gmail Server

Aug 16, 2010

I'd like my Android app to receive notification when new messages arrive in my gmail account. I realize that the Android gmail client does not broadcast notification when it receives messages. Instead I want to utilize the gmail server's Cloud to Device Messaging capabilities to do this. I read the article at http://code.google.com/android/c2dm/ - the only "missing piece" for me is to understand how my app sends a
registration ID to the gmail server. Can someone please point me in the right direction?

Android :: Can I Selectively Delete Receive Emails Off Of POP Server

Jun 29, 2010

I used to have a BlackBerry. The global setting was to leave email on the POP server. However, when I deleted emai(s) from the BB I was asked if I wanted to also delete it from the POP server. This was handy in that I could selectively delete junk email so that when I got back to my computer I didn't have to bother with them. The Android doesnt seem to have this capability on an email by email basis. You have to set a global setting for the application for all email. Am I missing something or can I actually selectively choose emails to also be deleted from my POP server.

My Configuration: HTC Droid Incredible on Verizon Wireless network. 8GB memory card. Android 2.1 OS. Home computer = iMac running v10.6.3 Snow Leopard. I use Apple Mail, iCal and Address Book on the iMAC. I use a POP3 server for email. I have a Google Gmail account; which I only use as a go-between to sync contacts and calendar between my iMac and Droid I dont really send/receive from Gmail. I link my iMac to Google to sync contacts and calendar events. I link my Google accounts to my Droid to sync my contact and calendar events. I only open up my Apple Mail application on my iMac when Im at the computer, so that I can get incoming email on my Droid. I have accounts on Facebook, LinkedIn, and Twitter. I use a Plantronics discovery Bluetooth 925 headset as well as a wired over the head headset with a jack adaptor.

Android :: Send And Receive Sms Both Way?

Apr 28, 2010

Is there an app to send and receive (in sms both ways)? All the phone numbers that I text (or texted to me) appear on our family bill. Since there seems to be no way to stop that; I am trying to find a simple sms to sms app.. a paid one without ads that is as simple to use as 'regular' texting. I also assume a paid app will bypass the fear of me being a spammer since they will have all my information.

Two Android Clients And One Java Server?

Mar 5, 2013

I've created a java server and an android client (A), the client(A) gets it's GPS coordinates and sends them to the server, I need the server to send them to client(B). I'm not entirely sure as to what to do, whether I should have separate ports etc or what.

Below is my two clients and server

SERVER

[HIGH]import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.Scanner;

[code].....

With this, I run the server, then run CLIENT B in the emulator and CLIENT A on the device, once I run CLIENT A, CLIENT B force shuts.

CLIENT A / SERVER connectivity is 100%, it prints to console (for testing). What I need to try to find out is how do I send the data to CLIENT B, I have used different ports and i'm sure that's why CLIENT B force shuts.

Android :: Communication Between Java Client / Php Server App?

Feb 13, 2010

I have a simple Java client application (Android app). I have to write a PHP server application which receives a request from the Java client application to write some data to a MySQL database or read some data from the MySQL database. It should respond with a status message (Write failed/success) or the data requested respectively. How would I get the Java client send a request and receive the reply from the PHP program and how would the PHP program receive the request and send the reply? I have googled about SOAP and REST architectures, but looking for a simple tutorial which will allow me to implement this simple program.

Android :: Send And Receive Text Functions?

Feb 5, 2010

Any way to get at the Send and Receive Text functions of a phone? In other words, is there a way to transmit a text such that another phone, within range and using my app, could receive that text? Proposed app: The_Haiti_Phone: All cell towers and land lines are down. I would create a text msg to my wife's phone and my special app would send it. All cell phones in range would pass it on. When the packet's receiver's ID matches a cell phone's ID, the msg displays to the user. In summary, in a catastrophe, all cell phones with my app act as cell towers.

Android :: Sending / Receiving Java Objects To Server

Sep 23, 2009

I have a Tomcat Server in front of a Servlet that gets/stores information in a MySQL Database. My Android application needs to get/ put information on to this server. I control both ends of the communication, so I've basically been exploring the "best" way to send information back and forth. So far, I've tried Jackson for JSON and the native Java Serialization packages. My object is relatively complex and completely serializable.I have no desire to write a "custom" guy at all, as I doubt I'd actually be able to improve on most of the packages.So with that being said, are there any other strategies/packages I should try to get information to/from my server?
