I previously had my gchat setup to be online all the time.. for some reason, I get logged off when my phone sleeps, or within a short preiod of time after my phone sleeps. I also do not get email notifications when the screen is off. I have to unlock the screen to get my updates now. Any idea how to change this back?I was also wondering about how to change the frequency of checking email and other updates, etc. to save some battery life

when my Talk was going off line and saying "Lost connection to sever. Messages will be sent when online." This happened anytime the phone was idle for more than a couple minutes. I changed the seetings in Talk to automatically sign in, and uncheck the option to set status to away when the sceen is turned off. This did not help, so I made sure my data-always-on setting was on, and it is. Sometimes it would not even tell me it was offline until I tried to send a message, then it would give me that error. Other times, all my friends will be greyed out for a couple seconds until it reconnects to the server.
This is an Evo I got replaced by RadioShack on Friday, 7/16, since I was having sceen issues with my first one. I never had any issues with my orginal phone. Yesterday, I was noticing a lot of my Gmail messages were coming in in groups, and normally when I was using the phone. Today, I sent an email to both my gmail account and myemail@mydomain.net email which is managed by Google, and neither of those emails were recieved until I turned my sceen on and started doing things on it. I have also noticed that if I turn my sceen off, background downloads pretty much come to a halt. Like I said, I have my data to always be on, so this is not the issue. I am using mainly 3G for data. I have done about 5 hard resets, and tried my Talk client before installing any apps or setting up my second Gmail account, and this didnt help the issue either..........

If my screen locks while I have a wifi connection, then the connection is lost when I unlock the phone.First, is this perhaps deliberate, to save power? Also, either way, when I unlock the screen and go into wifi settings, I see that the phone is trying to make a wifi connection, but it never succeeds, even though it's my home network and I'm in the same room as the router. It just states 'Obtaining address.

I was running the JI6 2.2 with cognition beta5.5 and was attempting to update however I needed to swap kernels since the current kernel didn't verify signatures. I was using vmware on a mac and i started it but then continued to use the mac side however the computer disconnected the phone from the windows side and now it is stuck showing an image of a phone next to a computer with a triangle with a ! in it between the two. Pressing all hardware buttons does nothing but black the screen and go back to the same screen. I've taken out the battery, sim, unplugged the cord, everything. Can't get back into download mode to redo the kernal swap. It's definitely connected to a valid, and working, usb port and i am now on windows itself instead of vmware. What do I do?

I have followed the "Hello World" example from Google's Android developer's guide. When I try to run the application in the SDK emulator, nothing happens. The emulator startd up nicely, but after that nothing happens. I can't even see the application in the app tray.
I am using Eclipse with the Android add-on installed.

I am just starting to get setup for android development. I have installed pulsar and the proper sdks I think. I want to develop for the droid x.
I can't find any information on how to create a new project using the installed sdks. Shouldn't there be a project type for android? Nothing like this is showing up.
Are there any tutorials for getting started using pulsar for android dev?

When viewing sites with a lot of Flash ads like GameFAQs I get an annoying popup telling me that I have lost the data connection and the page could not be loaded. Only the ads are not loading, but I'd like a way to ignore or fix this.

I am checking to see if my app has a network connection Whenever I rotate my screen between landscape and portrait this method returns false. It makes me wonder if Network connections are getting killed during the rotation?

Took my HTC Desire to Italy and since then have lost all mobile data connections - though works fine on WiFi. Switched on airplane mode for flights, and switched off data roaming to reduce overseas costs. But when switched back on to use internet couldn't get any network connection. Now back in the UK still same issue - no internet, and cannot send MMS picture messages - even when in strong 3G signal Tried all the options I can find but no joy at all.

After reading the forums and changing settings and doing a few battery cycles, I had been getting really good battery life of at least two days on medium usage and 3 days on light with my connection not having any real issues. Then, 2 days ago I installed weatherbug and beautiful widgets. While I enjoy both, it seems like my network connection goes down fairly often now and I need to turn on wifi to check email or do anything else web related. Has anyone else lost their network connection and been able to narrow down the cause? I'm hoping it's not one of these two, but I can't imagine what else it would be.

When my data connection (3G) is lost due to lack of signal sometimes it never reconnects again, despite being in an area of high signal strength. I have 'always on' mobile internet toggled. To solve this I have to turn the phone off and on again, which is annoying.

I used flash tool to try to install recovery on my Lenovo A750. I used DA_PL.bin instead of MTK_AllInOne_DA.bin as download agent.
Now when the phone is turned off, it is not recognized (no MT65xx), and I cannot use the flash tool again. Beside this the phone works fine including 'regular' USB connection. What is "download agent" and what did I do wrong?

I have a question about Google Talk. Is there any way to keep it from disconnecting after a while after the screen has been turned off? I have "always-on mobile data" active but after a minute or so after turning the screen of Google Talk disconnects and I don't receive any messages until I manually turn on the screen and wait for it to reconnect and retrieve the new messages.Just to note it doesn't actually show the splash screen saying signing into Google Talk it just says "Lost connection to server. Messages will be sent when online" bellow the most recent message.

Why is my phone constantly giving this vocal notification out? It is constantly searching for a signal? It happens about once an hour, and I'm guessing it's the source of my battery drain issues the last day or 2.

I've just noticed that I no longer get a notification of "Charge Only" in the top bar when I plug my HTC in to my PC via the USB cable!
I've gone into the settings for "Connect to PC" and it doesn't matter what I select, I still cant connect to use "HTC Sync" or "Disk drive" and yet the orange light comes on and the battery indicator says it IS charging!
I used to have it set to charge only and if I wanted to sync or copy to the SD card, I'd just drag down the top bar that lists widget locker and my mobile internet usage and I could select it and choose what I wanted to do - only now there is nothing there to select!
I've today replaced the trial power widget with the "Widgetsoid switcher" - could that have something to do with it? - I've tried adding USB connection and USB tethering and they dont seem to work either!

New to Eris and have set up Wifi to connect to home router (Verizon FIOS Actiontec). Successfully connected (accepted WEP) but get very weak signal and then lose connection. I've turned off "Mobile Network" but still have this problem. I am one room away from router and receive full signal on iMac and printer but only a dot under the Wifi symbol on the Eris. Exchanged a Motorola Droid (which received and held full signal -- as did my prior iPhone)) for Eris. VZW tech support clueless and immediately sent me to HTC support. While they tried (had some not very good explanations -- battery not pushing enough power) still nothing working. Any advice/help would be greatly appreciated -- this is the only downside right now.

for whatever reason today we lost our internet connection at work. Now I work for an airline doing charters and today we added a second flight to each shift. So I tethered my phone for the 3g and just plugged it in at the end of the day to charge it. Needless to say it handeled 300 passengers/customers easy. Changes, bag fees, checking in and selling for a solid 8hrs today! I don't think I'll ever get another cell phone ever. Maybe a bigger SD, but phone, probably not.

So I recently rooted my phone and switched to the Kangerade 1.1 rom running a chevy kernel. I pretty much have no issues EXCEPT for the fact that maps wont function unless I am on wifi. Once I am using 3g I just get data connection lost, and then it loops....I am using version 4.3 of maps, my wife's phone is also rooted with kangerade using a p3 kernel but with maps 4.2 and she gets the same results.

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.

I'm trying to work through their notepad tutorial and it describes how the Eclipse project should automagically build and re-generate the auto-generated code when a file is saved. That wasn't happening, and looking at their debugging, they suggest the "reset adb" link in the DDMS perspective in the Devices panel. When I try to do that, I get the following output which I assume is bad:
[2010-01-03 23:09:51 - DeviceMonitor]Adb connection Error:EOF
[2010-01-03 23:09:51 - DeviceMonitor]Connection attempts: 1
A quick Google didn't reveal anything particular useful. What are the next debugging steps and/or what might be the issue? Update: So this actually isn't a problem like I thought it was, but I'd still be curious what this message means if anyone knows.

Long time reader, first time poster here. How does one know if the Epic is using the wifi connection as opposed to using the 3G connection? When wifi is connected both that and the 3G connection shows at the top. So which one is in control per se? And how can it be verified?
