Android :: Network Connections / Access Points

Jul 16, 2010

I have some code that uses a network connection. I create a connection by calling openConnection() on a URL object. Is there any documentation that explains how this process works? Which access point is being used? When that access point becomes invalid, will it automatically switch to another accespoint? etc. I would like to use only WiFi access points and otherwise fail even tho 3G or GPRS could be available, is that possible?

Android :: No Phone Signal In Emulator 2.1 - Disable Network Connections

Apr 30, 2010

I only get a phone signal about a third of the times i start the emulator. I've read on these groups that you have to have an internet connection before starting the emulator. Since i'm connected to the internet 24/7 :) this is not the problem I've also read somewhere that you should try do disable all other network connections (which i've done) and the problem persists. I'm using Windows 7 and Android 2.1 + API's emulator. You received this message because you are subscribed to the Google Groups "Android Developers" group. To post to this group, send email to android

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 :: Maximum Number Of Connections

Jul 29, 2009

I've written an application which involves a lot of simultaneous connections to different servers. I've noticed some big stability issues with this as sometimes the program crashes totally (not just ANR, but a segfault type thing). What's the recommended number of maximum simultaneous connections for speed and stability?

Android :: Bluetooth Concurrent Connections

Sep 14, 2010

For the buzzer round, I was thinking of writing 2 app for android (we have a few handsets), one for the quiz master and the other for the contestants.The contestants will be connected to the quiz master through bluetooth.After reading the question, the quiz-master clicks a button in his/her app, the button in the contestant apps will be enabled for X seconds. As soon as a contestant clicks his/her button, the quiz master's app will flash the name of that contestant.Is it even possible to have multiple connections and accept concurrent (or multiplexed) messages from them in bluetooth (something similar to select() in unix/c)?If possible, where should I look for any examples? What kind of problems will I face trying to develop this (I know reliability is an issue here) and how to avoid them?

Android :: HttpsURLConnection And Intermittent Connections

Jan 31, 2010

I'm hoping someone could help me out with intermittent connections I'm getting using code with HttpsURLConnection.

The code I'm using is below:

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

The connection works the first time everytime when I use it to pull a json file. However, when I use the connection again to send a command, it always fails the first time. It then typically works if I send the
command quickly ( within 5 seconds), but fails if I wait a while. I don't think its a SSL issue because it connects the first time correctly, but I could be wrong here. I also tried many different
variations such as adding:

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

However, I had no luck. Any help would be greatly appreciated.

Android :: App Design For Multiple Data Connections

Oct 18, 2010

I am working on developing an application that requires me to establish multiple client-server based connections. Connection can be of two types where the Android device can be a server or a client. I can have up to 6 - 8 connections. Once the connections are set-up they need to be running in the background and are not typically affected by UI actions.Since each connection can be blocking, I am wondering what is a good away to design this app. Should I have two services for handling the server and client connections? Each service could have a "connection manager" that can spawn new threads when necessary. Or does creating two services even help? I presume spawning new processed would not be good as they will be expensive. Is this correct? I would appreciate any suggestions. Also, if this use case is not typical please let me know if you need more information to make any recommendation.

Android :: How To Use Http Connections Like TCP Socket In Java

Mar 9, 2010

may be asking a bit much here but I have faith in the community so it's worth trying. I'm making a game and I'm trying to pick the connection type to use for communicating between a Java mobile client and a Java server backend.Socket programing in Java is easy - there's a lovely tutorial on the subject and two way communication is trivial.Trouble is that on a mobile client (Android) it's not guaranteed that the cellular network will let you make TCP connections. That makes me think using an HTTP connection is the way to go. HTTP connections are request based but I need a way to push notifications from the server to the client. It seems the solution to this problem is to use 'long polling' I have read a bit about it but have yet to see a simple example for what I'm trying to achieve.Again I might be asking a lot but this seems like a fairly common problem, is there a library or framework I can import / use to wrap a Http connection and provide a two way long standing connection (That reconnects automatically etc). I read a bit about cometD but it doesn't seem to have a Java library that I can just pick up.The communication I need is not heavy, not constant two way streams of data just occasional updates either way to keep the game going.

Android :: What Happen To Existing Connections When Switch Between 3G / Wifi?

Aug 18, 2010

Assume that, I have a TCP connection that doing heavy data transmitting on my 3G network; and I walked home, Android switch to my home Wifi automatically. Now what happen to the existing connection? is it simply disconnect? or it will keep going, only the new connections will use wifi?

Android :: Impact On Existing Connections When Switch Between 3g / Wifi?

Aug 18, 2010

Assume that, I have a TCP connection that doing heavy data transmitting on my 3G network; and I walked home, Android switch to my home Wifi automatically. Now what happen to the existing connection? is it simply disconnect? or it will keep going, only new connections will use wifi? In addition, what if I walk away from home, wifi lost signal and switch to 3g? It should be safe to guess the connection is dropped. For my application, do I need to handle the reconnection or there is a auto fall back solution.

Android :: Server Socket Accept() Not Accepting Connections

Oct 27, 2010

I am trying to setup at ServerSocket on my Android phone, and send a char or int or anything from my computer. The code on the phone creates a ServerSocket and then blocks whilst waiting for a connection(plus some more bits if the socket is created. But I'm not getting this point, so left that out!)Basically, the phone is getting to accept, and the computer is not connecting. The xx.xx.xx.xx is the public IP of the phone I obtain programatically (and it matches up with checking on whatismyip.com).I have set the INTERNET permission on the phone. I have also been able to do this in reverse (ServerSocket on pc, client on phone).

Android :: Best Practices For Snappy Mobile I / O On Slow Connections?

Aug 12, 2010

I have a mobile app, which is pretty data driven, though only through text and images. In the current version each click or touch requires pulling new data from the server (appache/php). With network delay this easily takes 1-2 seconds for the first content to appear, which is far too long. I have heard about and considered the following options, but are not sure if some of them might be counter productive, or if I have left something important out?

Download all data from the start, in a big bunch with a loading screen? Run a prefetching thread, predicting and downloading data the user might want, in the background? Keep the connection open to the server at all time? Load different parts of the data in different connections in parallel? (Similar to facebook) Use heavy data compression? A comprehensive article on the matter would also be a good answer.

Android : Apps That Control Data (3G) Connections With A Schedule / Timer?

Jun 17, 2010

I am knew to android and am absolutely loving it on my Desire, so glad i never went with a certain fruit company

Anyways, i have had a search around here and on the market place and cannot find an app that suits my needs.

Basically, i run timeriffic (which is fantastic by the way) and mostly i use a wi-fi connection. However there are times when i know there is no wi-fi around eg. when i travel to work, so i have it turned off. What i would like to know is if there is any app out there that would allow me to schedule a time to turn on my 3g data connection (i have APNdroid installed and 3g disabled as default) for those periods when my wi-fi is off so i always have a data connection.

I did see the app Data on Demand and this would have been perfect but it did not work with my Desire.

Can anyone using a Desire let me know if they have tried Data on Demand and got it working and what conditions it was working. Can someone recommend an app that meets my needs? I guess if not i will need to contact the developer of timeriffic (who i have seen around here) and see if there is anyway he could intergrate with APNdroid and control 3G data connections.

Android :: Possible To Force Network Traffic Through Wi-Fi Or TMobile Network?

Mar 2, 2009

I'm wondering if, with the G1, it's possible to force the network traffic to pass through the Wifi or through the Cell GSM network. I need to force an application to connect through the tower network to get some login information. Is this possible? Anyone have any ideas as to how this would be possible? I'm trying to accomplish this inside an app with the Android SDK (Sorry I wasn't more clear about that originally)

App Membership And Social Connections

Apr 20, 2012

I have searched for this for a while now and have not found what I was looking for (if something like this even exists). Is there an SDK of some sort or a package program that would basically give a place on a server for a database and a membership system that is easily integrated into a android app I am developing? Something that would connect the users in my app like they do in instagram, or words with friends, or pretty much any other multiplayer game. (i am not looking for a facebook connect, or a twitter connect. just something that connects just my app together so to speak)

General :: Android 4.4 - WiFi Is Intermittent / Buffering / Dropping Connections On Nexus Devices

Jan 6, 2014

I've recently upgraded my Nexus 4, Nexus 7 and Nexus 10 all to Android 4.4 and as soon as I upgraded my Wi-Fi has been awful.The Wi-Fi is incredibly unstable, steaming media has major buffering / intermittency issues, messages sent over instant messaging apps are sometimes instant and sometimes take 30+ seconds to send.

Skype is the most telling of the issues as it randomly loses connection and my notifications literally never come through..Router Wi-Fi Settings: I've tried Channels, 1, 2, 4, 6, 8, 10 and 11

I've also tried adding
Code:
gDataInactivityTimeout=200

to the WCNSS_qcom_cfg.ini file as found:URL>...Wi-Fi is Always On, Wi-Fi Frequency is Auto or 2.4, Wi-Fi Optimization is Off.The wireless / wifi works fine on other tablets, laptops and wireless devices just my nexus devices on 4.4

Motorola Droid :: OpenVPN Connections

Nov 10, 2009

Several threads have indicated that the Droid supports OpenVPN connections, but for the life of me, I can't figure out how to configure this. The only VPN option that even looks close is "Add L2TP/IPSec CRT VPN", but I can't figure out how to load the user and CA certificates...hell, I don't even know if this is the correct option for an OpenVPN connection.
