Android :: Emulator Loses Network / Connection Error

Jul 16, 2010

I wonder if anybody has ran into the issue where a running emulator would lose network connection all at a sudden for no obvious reason. And I am sure the computer running the JVM is still online.Restarting the emulator seems to fix the issue but it's been a major PITA for me as it interrupts the work flow.I am using 2.1 SDK 7.

General :: No Network Timeout When Connection Lost On Device But Works In Emulator

Feb 14, 2013

I'm developing an App that sends keep-alive packets to its server to ensure the connection is still alive.

The server is java based and thus easily to run. I run the server on a virtual machine (Windows 7). After my App is connected and the first keep-alive packet is received (it displays a message in its console output) I disable the network interface in Windows. This step is very important because by disabling it, there is no way to send any packet back to the client informing it about network changes.

The clients are configured to send every 25 seconds a keep-alive packet, so you don't need to wait long.

When you use the sample JavaClient on Windows 7 it takes less than a minute after the keep-Alive packet and an exception is thrown which triggers reconnection (which currently can't occur). This is the expected behaviour.

When you use the sample Android App on an emulator (tested Android version 2 and 4) it is the same behaviour. So in less than a minute after the keep-alive packet it recognises that the connection is dead, throws an exception, this triggers reconnection.

Problem is now when this App runs on a real device (tested several, Xpearia Arc S, one Cyanogen Mod 4 on Galaxy S3 and my Galaxy S3). I've waited 5 minutes, but there was no exception. This behaviour is reproducable.

Since this is a sample App, it uses no wakelock or service, so to test it is important to have it in foreground all the time (don't switch to other Apps or homescreen) and increase your display timeout to a few minutes to ensure that it doesn't go off. Use Logcat-Output to get informed whats happening, because there is no output in the App itself.

Now Sample-Code is in the attachement. Something had gone wrong. The Code consists of 3 Eclipse projects which you can easily import.

Android :: Android To Open Network Connection On Specified Network Interface - Network Type

Mar 6, 2009

I have been looking at the ConnectivityManager class documented at http://developer.android.com/reference/android/net/ConnectivityManage... .

I would like to know if an Android application can open a network connection (socket) on a specified network interface [on a device supporting multiple network interface types WiFi, Cellular, WiMax etc] ? I am looking for the capability for an application to open a socket on a given type of network for example over WiFi network or over 3G Cellular Data network.

If this is possible in Android, how would I code this requirement within the API Framework ? The ConnectivityManager enables an application to learn about available network connections and currently categorises them as either TYPE_WIFI or TYPE_MOBILE.

There is a member function in the ConnectivityManager class called requestRouteToHost(int,int) [url] which "Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful." Sounds like this would install an IP routing table entry to reach a given host via a specified network interface type (WiFi or Mobile). After calling this would it be sufficient for an application to open a socket and connect to the desired destination address ?

Or perhaps the application needs to bind() a socket to a local address of a network interface of the desired type (WiFi or Mobile) Or by setting a socket-level socket option of SO_DONTROUTE ?

Android :: Emulator - ERROR - User Data Image Is Used By Another Emulator

Apr 13, 2010

Finally strace gave me this:

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

And several other attempts to call "link" that also fail (sshfs does not support hard links).

Is it possible to change the emulator's behavior to create lock files somewhere in /tmp (using some hash of image path as lock file name)? I am OK to try this myself: which repositories from https://android.git.kernel.org/ are necessary to rebuild the emulator alone, and where in the sources is the code responsible for image locks?

Android :: TCP IP Connection Via Mobile Network

My test version will establish a connection if I have both phones on a lan using wifi but when I use T-Mobile's network a connection is not established. Could this issue be a port or ip address?

Android :: Way To Make HTTP Connection Using GSM Network?

I need to make HTTP request on Android using GSM connection, not Wifi. My current solution is to disconnect from all wi-fi connections and perform a request. Is there any better solution? I could not find any relevant methods in the API (I looked in package org.apache.http, but it seems it is completely unaware of what type of connection should be used).

Android :: Programatically Selection Of 3G Network Connection In G1?

May 11, 2009

I'm working on some data transmission program and current it works alright on WIFI connection.

However, I understand that if I am in an environment where there are both 3G and WIFI coverage... the phone will (by default) be turned onto the WIFI network connection.

However, if for some reasons, I wish to be connected directly to 3G (e.g. 3G is more stable in public WIFI area).... is it possible to do so programatically on the Android phone? If i'm not wrong, it's possible using the ConnectionManager API, am I right?

May i ask if anyone has done something like that and don't mind sharing the code snippets to do so , or point me to the right direction for this?

Android :: Emulator DNS / Network Posted Fix?

Jan 24, 2010

I've read many postings about problems getting the Android emulator DNS to work properly in certain situations. I have a simple app that makes an HTTP connection to a server on the Internet. If I use an IP address using the latest version of the emulator it works fine. If I use the domain name it throws a java.net.UnknownHostException: Host is unresolved: exception. The identical code works fine on any actual device. Has anyone figured out how to fix this situation? I've spent days trying everything, from using proxy servers to setting up and running a DNS server on my development machine. This situation/experience is a shame, because the emulator seems like such an impressive and well thought out collection of tools for developing and testing apps. However, it is currently useless to me. Is there anyone who can help? A prior thread on the same issue-appears to be the same situation: http://groups.google.com/group/android-developers/browse_thread/threa...

Android :: Connect Two Emulator Instances Through Network

Apr 7, 2010

I'm doing a distributed system using Android for my research project.In order to test it, I have connected two emulator instances in the same host machine. However, I need to put these two instances in separate host machines and make them connect through the local network (Wi-fi).I have seen that the emulator runs behind a virtual router, so it seems that I would have to somehow configure such virtual router, in order to forward my requests.

Android :: Network Access Is Slow In Emulator

Aug 5, 2010

I've noticed very poor performance in the emulator (1.6 and 2.1) when trying to complete the forth statement below. It will take 5+ minutes running in the emulator. Interestingly, when I debug on my phone it's not nearly as bad at maybe a minute or so, but still not great. Running the app on my phone without debugging yields great performance (seconds). URL url = new URL(CommonProperties.BASE_SERVICE_URL + "param=1"); DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = factory.newDocumentBuilder(); Document dom = builder.parse(url.openConnection(). getInputStream()); is there something I can do to speed up network access while using the emulator? Has anyone noticed anything similar?

Android : Want To Create - Establish Ad Hoc Network On Emulator?

Sep 23, 2010

I am developing an application for android based cell phone from emulator. The application i am developing requires ad hoc network. I do not own the phone or can't get it from anywhere else. So I want to create and establish ad hoc network in that emulator only. I am using standard ADK 2.2. I read somewhere that the information and settings of networks are read through a file called tiwlan.ini. Is this file available even for emulator? If it is, where is it located inside it? If its not, can i copy the file available on Internet and put it somewhere inside my emulator and change system path to read network information to that file's path? If even that is not possible, is there any solution available by which I can establish ad hoc network on emulator?

Android :: WiFi In Emulator - Create A Local Connection

Jan 31, 2009

I've been trying to create a local connection to a computer with a Socket from the emulator thinking that it would automagically uses a emulated wifi connection. It doesn't work, in particular because wifi is not supported on the emulator:

- Does a Socket connection automatically choose the fastest connection (the wifi one if it exists).

- Why wifi not supported by the emulator? Will it be?

For those in countries still not blessed by the grace of having the possibility to buy a Gphone, that can be useful...
