General :: Connection To Oracle Database?

Sep 12, 2012

We are developing an Android application will connect to Oracle DB. I have problem with JDBC library dependencies.

I always get (java.lang.ClassNotFoundException: oracle.jdbc.OracleDriver) error, this happened when the Class.forName ("oracle.jdbc.OracleDriver") didn't find the JDBC library. At my case I double checked that my ojdbc6.jar library is existed correctly at build path.

Is there any farther configuration I've missed ? Regarding libraries dependencies, is there any difference at development between J2SE and Android application ?

IDE: Eclipse SDK 4.2 with Android
Android target platform: 2.3.3

Android :: WebView-based Browsers Accessing Protected Resources Through Oracle Access Manager -OAM

Oct 5, 2010

We have a website that makes use of OAM for single sign on (form-based authentication). When we submit credentials to WebGate / Access Server the authorization succeeds, however after the authentication is performed, the form action (as configured in the Authentication Scheme - with passthrough:no) returns a server error instead of redirecting to the originally requested URL.

If we use Mini Opera, we are able to get authenticated and forwarded properly.

This problem happens on numerous Android phones (versions ranging from 1.5-2.2), as well as the Emulator provided with the SDK.

This is proving to be a real problem as the default browser on Android phones is not able to get access to our sites(and this is the only browser that is having this problem).

I have created a WebView-based custom browser with the hope of seeing a client-side error and tried trapping every possible error....none show up....

I have tried to trace all of the http requests and found only a single difference in the requests... the http header for Connection:keep- alive is not sent by the Android WebView.

I have provided some tracing info below...

Android USB Communication

Dec 17, 2012

I am new to android programming and I am trying to set a connection with the android as a host. I have included the following imports:

import android.content.Context;
import android.hardware.usb.UsbDevice;
import android.hardware.usb.UsbManager;
import android.hardware.usb.UsbInterface;
import android.hardware.usb.UsbEndpoint;
import android.hardware.usb.UsbDeviceConnection;
import android.content.Context;

My problem is when I use this code :m_usbManager = (UsbManager) getSystemService(Context.USB_SERVICE);The eclipse editor shows a message saying that getSystemService(String) is undefined for the type CPrinterCommands(The class that I am using). Quick fix gives as a solution to create a method called getSystemService, however I can't find why I would need to create a method, all the examples I found, none of them had a method getSystemService.

Android :: Communication With PC Client?

Dec 10, 2009

I wrote a TCP socket client, an android application. On my emulator, it can successfully connect to a TCP sever running in my PC. But, when I deployed the the apk into my real phone, HTC g4, it dosen't work. An exception was raised said "java.net.SocketException: Network unreachable". The situation is, my handset was connected to my PC via USB, and no other connections were available. How can my android application connect to a PC server in the case. I don't know if we can use socket over usb connection. If yes, then why my application doesn't work. If no, then how?

Android :: In Process Communication

Mar 30, 2010

I have a design problem with my Android components.

My activity is starting a service which is doing the work in the background. What I want is that the service informs the activity about state changes. How can I do this?

Normally I would add an observer but the activity has no reference to the service. Then I was thinking to take AIDL but this is more for inter-process communication.

How is it possible that the service informs the activity about state changes? Both are running in the same process. What can you recommend?

Android :: Multiplayer Game Communication

Sep 6, 2010

I have to develop a multiplayer game. The game will be supported between different platforms: 1) Two android clients. 2) Android client and a web application (something like facebook and android client for Texas- Holdem game).

I want to handle the communication between the platforms through a service.

I have asp.net (C#) background so I thought to implement the communication using WCF service but I am not sure this is the best choice?! Can you please tell me if my choice is good or should I choose other approach to implement the communication?

Android :: Inter Process Communication

Mar 19, 2009

Just say I have two applications, each with one activity running on separate processes and I want to send a simple string between them. For the purposes of this example, let us say I have a button that sends whatever is typed into an EditText view to the other application where it is then displayed. Do I have to expose a remote interface via a service that co-resides between the two applications? Or can I do something simpler (is there a way to pass data between processes without defining your interface using AIDL)? Thanks for clearing this up for me, as I seem to be struggling with performing IPC at the moment. I'm pretty sure I have to use the Android IPC path and generate a remote interface using AIDL. I'm just not sure about the binding to service part.

Android :: Communication Between Droid Devices Over 3G?

Aug 25, 2009

I'm not *entirely* sure this one is supposed to go here, but anyway :)

Assuming I have two Android-powered devices, connected both to the same 3G network; does the current API of Android allow to have a Service running on one of them being contacted by an Application running on the other one over this 3G network or do I have to go for a more traditional network (e.g. WiFi AP, Bluetooth) ? If so, how do I do it ?

I saw the usual Socket part in the API but it is not clear to me whether this is the way to use the 3G. I also found another discussion related to communication between a laptop and a dev phone ("Sending data to android dev phone using 3G connection") so it seems to be possible.

Does anyone have some details about how to do this?

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 :: Multiplayer Game Handle Communication

Sep 7, 2010

I want to develop a multiplayer game. The game will provide communication between different platforms:

1) Two android clients (client applications that communicates through a service).

2) Android client and a web application (internet application) which is something like facebook (web) and android client for some kind of game. I want to handle the communication between the platforms ((1) android to android and (2) android to web) through a service.

I have asp.net (C#) background so I thought to implement the communication using WCF service, but I am not sure this is a good choice. Can I handle the communication using WCF or should I use other approach? Can you please recommend me a good approach to implement the communication?

Android :: Options For Client Server Communication

Nov 6, 2009

I'm currently in the research phase of my dissertation project.My project is a ticket booking system for a mobile device and I have chosen to target Android.I anticipate the need for a client/server architecture with a central server, and so am currently looking at how Android could communicate with such a server. The server would grant the client access to ticketing information, and the client would send information about ticket bookings to the server. I'm looking at Java EE for the server as Java is the language I'm most experienced with.I'm aware that Android comes with java.nio and java.net, as well as some org.apache packages, but am also looking for libraries/technologies that would be possible to use with Android.

Android :: Background Service - Intents For Communication Between UI

Jul 6, 2009

I'm writing an application that consists of a background Service and one or several Activities acting as UI towards this. There will most likely be several different UIs for this service that will installed later on, like custom widgets or UIs. The question is how to solve this in the most efficient way. Is it better to only use Intents for communication between UI and Service (sending control commands with Intents from the UI and listening for Intents from the Service for state and data updates) or should I prefer using IPC communication (AIDL -> Java Stub, binding to the service etc.)?

Since the UI might be started long after the service is started, I would either need to use sticky intents to signal current state, or have a very frequent intent sent by the service if choose to go with the Intent-based design. Which one would be the preferred way in that case? I've read that sticky intents are much more resource consuming than normal intents, but are intents more consuming than IPC directly towards the service? Also, is really an AIDL the right way to allow third-party integration? Intents sounds better, since they are also asynchronous.

Android :: Communication Between Two Emulators Located On Two PCs Connected Via LAN

Jun 4, 2009

I am trying to port a VoIP application based on SIP protocol to android.

I want to test this application first on two emulators running on two different PCs connected via LAN.

The problem is that, the communication is not happening when I run the application on two PCs. The same application works when I run it's non-android version on the same PC's.

I have identified the following problem. Let's say there are two computers C1(192.168.1.101), C2(192.168.1.102) connected in a LAN.

Emulator E1 is running on C1 Emulator E2 is running on C2

The application uses UDP protocol and the port being used is 5060 on both computers.

I have setup port forwarding on both the emulators. This is the command used for that in Android console. redir add udp:5060:5060

When we make a voip call from E1 with the URL 192.168.1.102:5060, then E2 responds to the call, but what ever E2 sends in response is not coming back to E1, and hence E1 is timing out.

When I observed the log files, actually E2 is sending the response to 10.0.2.2:5060, which is the C2's loop back address(127.0.0.1). How do we resolve this issue?

I have gone through the developer guide where they have mentioned about two emulators communicating on single PC. But looks like this concept doesn't work when we run emulators on two different computers.

I tried 'redir' command for port forwarding and added INTERNET permission, still it doesn't work.

My question is, Is it possible to implement this communication on two emulators? and if yes, How to do this?
