Android : Unable To Simulate Network Delay / Speed - Fix?
Oct 20, 2009
An app I'm developing opens a TCP socket connection to a server. That works great, no problems. What I want to do is simulate network delay and slow speeds, but the changes don't do anything. I telnet in to the emulator console just fine and can set the delay and speed changes, but they don't affect my app in any way. Even disabling data entirely (gsm data off) doesn't do anything. However, all of the settings affect the browser, just not my app. I'm just using a regular Java socket (java.net.Socket). What am I missing?

I'm trying to write an application that needs to know when there is no IP network connection available. I am using the android.net.conn.CONNECTIVITY_CHANGE broadcast event along with ConnectivityManager to react to the changes in state to achieve this, but I'm having problems testing my set up in the emulator.I have tried both flight mode and pressing F8 to disable the "Cellular Network" but even with both of these engaged the application still "sees" the underlying network.Has anybody managed to find a way to simulate a total lack of network access?

I just recently got the D2 after having the D1 for a year. I loved the D1 and loving the D2 as well, except for a couple of minor issues, but one that is really bugging me is the speed of the network on the D2. I've tested with the D1 and was getting over 1Mbps frequently. I have tried in numerous locations, different parts of the city, different times of days, and keep getting very slow test results. On the status bar it reads 3G, and the tests come back at 129kbps, 102, 165. Horrible IMO. I have *228 many times, is there anything else I'm missing? Or is this a known problem? I've searched and came up with nada.

I was thinking that is there any way I can force my phone to work on specific speed like enabling high speed means you get max out of your network. Say 14.4mbps is what your device has, can I fix it to work at 7.2mbps? I feel doing that so will save your battery.

Whilst sitting in my home, with full bars for reception on my Galaxy S, I ran a SpeedTest on it. The icon on the 'phone displays a 3G symbol. Results: Download: 384kB Upload:482kB Provider: Tele2/Amsterdam,NL. 3G is really exceeding exceptions. This is on a 2Gb download data plan. Great (Feel the sarcasm )Is this to be expected? Regards.

I'm trying out the network speed emulation as described in the following link: http://developer.android.com/guide/developing/tools/emulator.html#net...
But is doesn't work, although "network status" command shows the correct values... I know it doesn't work by writing code to monitor the eth0 device in /proc/self/dev/dev, whatever speed I set, it seems always use maximum speed available to the host machine.

My N1 will not reconnect to a mobile network if it has been sitting for a few hours in a no-coverage area, such as a building. I cannot get it to reconnect, even after refreshing the network search in settings>wireless and networks>mobile networks. This action only leaves me with no result or a message saying that there was an error in searching or connecting to mobile networks. The only solution is to restart the phone. Every time I try to turn the phone off after this error has occurred, the shutdown sequence hangs until either I become frustrated and do a battery pull, or it automatically restarts itself.
Furthermore, the phone used to give me an error notification saying that the phone does not have carrier service. Now, it does not. I tried uninstalling all my programs and nothing has worked for me. I'm considering putting on the cyanogen ROM to see if it would fix this error, but I am hesitant to void my warranty. It's a pretty serious problem as I'm very frequently in a building where I don't get service. It's quite frustrating to have to wait to reconnect to a mobile network once I leave the building and hope that the error didn't occur or have to do a battery pull every time I realize that the phone simply won't reconnect.

I have a problem with a brand new Galaxy i9000 and the wifi. I have managed to add one wifi network to it that I use at home. I have a second wifi network that I want to add, called cat, but when I try to add it from the Add wifi network place, it gives the error: Unable to save the network. i have tried a power on and off. Is there a maximum number of wireless networks one can save, or is there a problem with my actual 'phone? The phone is very laggy as well, and almost impossible to use when 3G is active. (Load averages are as high as 30 sometimes).

I had the phone for about a month now and not changed anything but its just stopped sending. When i set it up initially the outgoing server was an ntl one which was suprising as i've always had to use o2 on other phones but it worked a treat on my ntl. but now its only sending mails if i am on home wifi connection not on the 02 network.

Serious issue here with my galaxy. I was coming back to Denmark from Sweden yesterday and my phone was working fine on roaming all this time. As my train crosses to Denmark, I lose the network, and very much since then have not been able to get it back. If I manually go into search for networks, it will take a minute or so and sometimes finally find some networks.
If I choose my home network, it will try for 2-3 minutes and fail 90% of the time and sometimes succeed.
That is act as if I was connected with 4 bars, but still, when I send myself an SMS from another phone, or try to call, nothing comes up. I know it is not the SIM, or the provider, as I have switched SIMs with another phone and the SIM works on the other phone, just like the other phone's SIM doesn't work on my galaxy. I am running Galaxo1.1, but as I said this problem started occurring without my even handling the phone at that time.

My phone has worked without a problem till last nite. I had a few texts and calls early eve with no issues at all then later on when I tried a text it kept giving me a 'message not sent' message? At first I thought it was an Orange issue so didn't worry too much but this am it's still the same? On doing a bit of investigating I have found I can no longer make calls either. If I try it it doesn't even get too a dial tone it just beeps and returns to the initial call screen.
The phone is showing full signal strength? When I go too call settings>additional settings it shows 'network or SIM error'. I have put my SIM into another phone and it works fine and another SIM that I know works into my Desire and have the same issues so it must be the handset. What do you lot suggest? If I do a factory reset will I loose all my photos etc. from my memory card? Or could I just un-mount it and then reset?

I have a stock inc and for some reason it won't connect to my home WiFi network. It will connect to other wifi networks. I turned off WEP just to take that variable out of it. No idea what the problem is. I have also hard reset it.

I've seen this problem on a bunch of other android phones but nothing specifically for wildfire.
When sending MMS I keep getting a notification saying 'message not sent. generic network failure' until it eventually aborts altogether.
I think the problem is at least partly coz I'm using an unlocked vodaphone handset on orange, so the APN isn't properly configured.
Ideally can somebody with a Wildfire or similar model on Orange give me the correct APN settings from your phone? Or at least link me where to find them - it sounds like every other provider has the details on their website but can't find anything on orange.co.uk

I am attempting to connect my laptop to the Epic Hotspot. My laptop is able to find SPH-D70002E (Epic) on my laptop's WiFi available network list. When I click on that, I get a Window's error message: "Windows is unable to connect to the selected network. The network may no longer be in range. Please refers the list of available networks and try to connect again." The SPH-D70002E (Epic) is full bars strength.

Phone has been working fine for about 2 months with data, MMS and 3G with 3 POP accounts and 1 Exchange account all sync'd up and working. Then, on Sat at around 7:30pm I realized the phone was no longer getting emails (Outlook was chiming away but phone on desk eerily quite). Picked it up and noticed 3G indicator wasn't there. Recycled power - No change. Updated firmware to R2BA020 - No change. The APN settings are correct and haven't been changed since working. AT&T Unlimited data plan is in good standing. So, although nothing has changed, I can no longer get any data (email/web/facebook/etc.) nor can I send or receive MMS. All of these work if I turn WiFi on but not over the cell network.

Ever since flashing the 2.1 leaks (V1 and then V2), I have not been able to connect to my university's WPA2-enterprise wireless network. After I enter my login info (the network uses PEAP with MSCHAPv2, so it doesn't need any certificates), the phone connects as expected and gets a valid IP address, verifiable with netcfg. Before any traffic is allowed to pass to the outside world, however, the device connecting has to go to an authentication page in a browser. When I attempt to go to that page, I get an error titled "Data Connectivity Problem" that states "A secure connection could not be established" which only presents an option to acknowledge the error.
Since I can't load that authentication page, the network is entirely unusable. I did not encounter this problem with 1.5, but since I'm running the V2 leak, reverting is not an option.Has anyone else seen this type of behavior? I can't identify if the problem is in the actual link not being established properly (seems unlikely, as the phone is given an IP address, but perhaps the PEAP layer is having some sort of issue?) or if it has to do with the SSL certificates used for the network authentication page (they're signed, but I'm fairly certain that the name if the site they're signed for is not the name that they've given the new auth server).

I run the emulator from the sdk version 1.1_r1 and when I try to make an outgoing data connection during a incoming call the data connection will not be esablished BUT it works fine if I disconnect the call. I have seen the same behaviour on other phones that run GSM instead of 3G. Are the emulator simulating GSM? If so can I switch to 3G or is there any other way that I can have a outgoing data connection during an incoming call?I have tried the "emulator.exe -netspeed" option but if I understand it correctly it only set the speed of the connection and not the connection mode.
