My Application needs to Download some bigger Files. I use a Service for the Download an show the Progress in a Notification. The Problem is that during that download time the user can switch from 3g to WIFI. In that case the progress stops but no exception is thrown.
How do i handle this situation properly?

I found that when my WiFi is on, when screen is off due to screen timeout, when I try to open screen again by pressing menu button or power button, nothing happened, I need to switch the mobile on again by pressing power button long press (not normal press to open as usual if you switched off manually)
someone told me because mobile is duos, may be you have only two gateway, when WiFi is one with access of data plan of two Sim cards, may be doing conflict, actually last week I switch data plan access between two Sims last week and I think this problem came with this action, I delete APN access points from one of two Sims but it didn't solve this problem.
How i can set the timeout for a DefaultHttpClient? and which function i must override to handle the event?
View 3 Replies View RelatedIn my Android application, it is noticed that when the device goes to sleep/standby WiFi is disconnected. When the device wakes up, it gets reconnected. Before making a httpClient.execute(..) call to remote server we check if the device is connected to n/w. When the data transfer is being done and if the device goes to sleep then Android runtime will switch to another medium for connectivity(3G,GPRS etc.)
Is the switch from WiFi to alternate cellular service say 3G, seamless? How do I wait for WiFi to become available again? Should I use Thread.sleep(delay) when the WiFi wakes up? I have seen broadcast actions when the WiFi state changes. In general, what is the ideal approach to handling WiFi disconnects in a mobile app?
Tried 4 ROMs so far, Skyraider 2.5.2 and 3.0, and Virtuous 2.7 and 3.0. My wifi completely turns itself off about a minute after beginning a phone call while on bluetooth. Can anyone please confirm if your wifi stays on and connected while on a bluetooth call, and if so, what ROM, radio and kernel are you running?

My queries are:
1)Does this switch happens automatically ? If yes,which part of framework or code does that?
2)Does the http request drop in such situation due to cellular hand off ? Is there any way to handle such hand off ?
3)Does gprs cellular connection reconnects automatically when WiFi gets disconnected ?
4)Which type of alerts or notifications normally user gets in such situations ?
Yours feedback and inputs will be of great help for me in this activity.
I can establish a connection using HttpUrlConnection.

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?

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.
View 2 Replies View RelatedI have found an issue. I have a server that uses User Agent header to identify the device that is connecting to it. But when i connect to the server using HttpURLConnection i get no User Agent header, but when i connect with the browser it sends the correct User Agent.
For testing i am using an echo server that replies with the headers it found on the request.
When i connect with browser i get: eg: User-Agent: Mozilla/5.0 (Linux; U; Android 1.5; en-fr; HTC Hero Build/CUPCAKE) AppleWebKit/528.5+ (KHTML, like Gecko) Version/3.1.2 Mobile Safari/525.20.1 Up.Link/6.3.1.20.06.3.1.20.0.
But when i connect by code with UrlConnection i get: User-Agent: UNAVAILABLE.
Does anyone know we i get different behaviors? How i can i connect in the same way the browser does?
If an app needs to download some critical data (without the data it cannot function) of several MB, what is the best practice? The app would start, a prompt would be shown to confirm download, download would commence, and the user would be prevented from going further until the download successfully completes. I don't expect the download would take more than, say, 10 secs over wifi but, of course, would take much longer over 2G. Is a service absolutely essential for this? Maybe there is already some code out there that takes a URL, downloads it in a service, and broadcasts a configurable Intent when the download has completed?

Can someone recommend a good app to automatically toggle wifi based on when I leave my house, which is the only place I use WiFi.
View 26 Replies View RelatedI seem to have a weird problem on my HTC Sensation. I have been noticing that when the phone switches from Wifi to 'H', the mobile data stops working. I can see the signal bars so no problems with making calls, text etc. I have tried putting phone into airplane more, resetting mobile data and a couple of apps that reset the mobile data stack. None of that has worked. The only way I have made it work is by restarting the phone - quite frustrating. The mobile data then starts working. It has only happened when 'H' is displayed as the mobile data.

I was wondering if there is a way I can have it automatically switch to the one with a better connection through an app or script of some sort or a way that I can at least make a shortcut on my launcher to do this?
now that I think about I could toggle wifi off and on but is there a better way?
Wifi is not working i Cant switch the Wifi on. I have a Note n7000 android 4.2.2 cyanogenmod 10.1 nightly.

I go out into cities alot, and I usualy grab a coffee in either a Costa, or a Nero. These both have BTFON WiFi hotspots. At the moment I can connect to these as I have BT Openworld at home. However, my BT contract is being cancelled tomorrow, they're bloody expensive, and as a result, my access to these hotspots will stop unless I subscribe to thier BTFON service.
If I stop my Desire connecting to these by switching off WIFI, will the phone then automatically switch to 3G for internet access?

View 5 Replies View RelatedJust two quick questions: When connected to wifi, do internet connections made on the device automatically go via wifi as opposed to 3g etc and if not then is there a way to organize which wireless connection 'methods' have higher priority (i am worried about excessive data costs). Second question is: Is there any multi tasking support on the Magic and if so then how do you switch between applications?
View 2 Replies View RelatedFor those of you trying to squeeze as much time out of the battery as possible, I came across this nifty program which I don't think has been mentioned yet: AppBrain: Y5 - Battery Saver - Android app on AppBrain Official: Y5 Battery Saver: Home. When you connect to a Wi-Fi network, it uses the GSM base tower identifier (CellID) to determine the location of the Wi-Fi network and stores it in memory. It does not use the GPS. I saved my home network earlier this afternoon and went out, Wi-Fi was turned off while I was out, then after I came home and started using my phone, I was connected again, so it seems to be working so far.
View 6 Replies View RelatedVery happy with the i9000 in the last few days of ownership, using launcher pro in place of stock but otherwise mostly unchanged. One issue we have is that after being at home overnight on WiFi, the phone doesn't automatically re enable 3g. To restore the mobile data you have to go into the network operator selection and re select Optus (our carrier here in Aus). Leaving it on auto doesn't help, and you have to manually choose it each time (ie: it "forgets" what I selected or something). Using apndroid to mangle the apn on/off doesn't help. Restarting the phone fixes it but obviously not ideal.
Have tried entering the code to change it to gsm only instead of the default wcdma/gsm auto with no benefit. When the mobile data is working, it happily switches between 2g and 3g, but will sometimes simply stop working as per the wifi overnight problem and I have to manually select the operator again. This happens very randomly and can go several days without drama, our only a few minutes. While this data won't connect, the phone capabilities aren't affected and you can make and receive calls fine. In fact if you dial a number it sometimes causes the data to re connect.
I'm using URLConnection to connect to the main server. The server implements digest authentication. If I connect to the server with java library, the connection is successful. But if I use the same code for android, the connection is rejected for the reason - username and password do not match.
Here is the code for my Java project:
code:...........
The above code works fine and I'm able to connect to my host server which is implementing digest authentication. I'm unable to use the same code for Android to connect.
Here is my android code:
code:.........
If the same code works for Java, it should also work for Android.
The code loops in the Authenticator as it finds username and password not matching in the Android code for some reason which in fact are correct. The code runs perfect for Java project.
I'm working on a Push Notifications library for Android (http://deaconproject.org/) that needs to take action if network connectivity is interrupted or changed - namely, it needs to re-initiate a server connection or pause its operation until network connectivity is available. This seems to work fine using and Android BroadcastReceiver for "android.net.ConnectivityManager.CONNECTIVITY_ACTION".
My problem is in testing the library - I would like to automatically test the library's response to a broken network connection, or a transition from 3G to WiFi, under various configuration conditions. The problem is, I don't want to sit with the emulator and hit F8 all day.
Is there a way to programmatically manipulate network connections on Android from within a jUnit test without resorting to toggling Airplane Mode? I've already tried issuing commands to the emulator via the console, manipulating the GSM mode, etc, but while the phone state changes on the display, the Internet connection remains up.
