I wanted to know if it is possible the communication between two Android Emulators started on two different machines networked.
For example
- Emulator A run on machine M1
- Emulator B run on machine M2
Can A and B exchange messages?
If yes, what ip address do I use?

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?
I know that iphone users can jail break to get the old school emulators and I think that by now, there are some emulators in the apple market. My question is on a couple levels...
- Without jailbreaking, can you get roms on the iphone for free?
- If so how?
- How well does the on screen controller work
- Is the small screen you have to use on the iphone emu an issue?
Also add any feedback you like and your opinion as well. I'm just curious that's all. Hopefully one of you has experience in this field
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?
Is there any way to allow communication between a program on a PC and an app on the Android through USB? I've notied some apps can sync through USB so I figure there must be a way.

Is there a safe way to identify and launch a particular emulator from a given application under Eclipse? I have a recent Eclipse/Java/ADT setup and I'm using the a variety of tutorials from Mark Murphy, Meier, and Abelson.
I am trying to communicate between two android emulators for communication , thus I am trying to forward port X to port Y on 127.0.0.1 where port X is the port I am transmitting too and Y is the one I am receiving . Is this possible and if so how do I forward the local ports?

I'm all down for paying for apps and stuff to support the devs but it would be cool if there are free ones out there that work just as well.

View 15 Replies View RelatedI like to add addresses to my phone book in Android. As a lot of my contacts live in buildings i also like to add the floor and apartment number to the address: Looking like that:
Street and Number, Floor and Department number
Town, zip code
State
Country
Example;
Av. Whatever 12345, Floor 5-A
Buenos Aires 1007
Argentina
When clicking on the address the GPS of my wish opens , finds the country, city but not the street because of the additional Floor and department information. Without this additional information everything well with Google Maps or Sygic.
So, how should i add this additional Floor and department information to my address without the GPS has problems to find the main location.Also from ICS on there is only one filed to add the whole address not as with Gingerbread where you had a field for street, city, etc.
Just getting used to my HTC Desire, after reading your forum I was comforted regarding battery life and it seems much better now than the first few days.
I see another post on this but no answer, the address book only gives one line of the address is then any way round this? Even my first pda a Psion 3 had the option of which fields to display etc. there seems very little option to format what is seen, not that I am unhappy about the rest but to have to edit to see all the address is barmy.
Another thing way back then that still is not found is search all fields of the contacts, i.e. to find a number of someone that rang on another phone.
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.
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?
View 2 Replies View RelatedI 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?
The Gmail address book on the Web contains a field for birthdays, so why not the Android address book? While I'm sure the app could undergo a lot of changes (and everyone would have different ideas) something as basic as a birthday seems obvious.

View 2 Replies View RelatedJust 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.

Sure its supposed to be flexible, but why not make it easy to create hello world and play around with a virtual Android phone? Both blackberry and iphone come with default simulators when you download the sdk.
