I was just wondering if anyone solved this problem. Googling gives tons of posts having this question but not one with a proper reply. I tried literally every combination of the following two pieces of code with and without proxy:
CODE:....
I am trying to connect to a site on my intranet (its not localhost). I've tried the following:
Setting Proxy inside Eclipse settings. Setting my own localhost and writing a small php script that takes the url, connects to it and then gets the file from the intranet site - This works from the Browser though! It does not work when I use the 10.0.2.2 IP address

An Android app I'm writing involves quite a lot of downloading of content (think podcatcher/RSS).
I would like to be able to give the user an indication of how many bytes they've downloaded, so they can make the decision whether they want to use Wifi or not.
To this end, I have found a way of counting the number of bytes read by the app, by wrapping an InputStream in a simple CountingInputStream.
However, this does not take into consideration basic things like packet headers and HTTP headers. More importantly, it does not take into consideration any compression that content may be encoded with.
So, how many bytes did my application download over the network? I'm not so interested in the number of bytes uploaded, but if know how, don't be shy.
I have gone down a fairly low level approach as I am feeding the input stream into an XML PullParser. I will also be needing to do a similar exercise with dumping bytes (images in this case) straight onto the SD Card.

I'm doing Major Project on my final year and I'm very new to Android plus I;m not good at codings. I need help with my login page.
I've created something like a database connection java file which is this:
CODE:.......
I've already created a database for users using SQLite. The database name is Users and the table is called User. The records inside the table are Username, Password, LastName, FirstName. I've inserted one user's info into the database. The problem is I do not know whether my UserDB.java is correct.
And I've also created login.java. Hardcoded Login page:
CODE:.........
So I want to know how I should apply the database connection on the login.java. Should I insert database connection something like db.Open();? I studied ASP.Net a few months back and I kind of forget most of what I've learnt. So how should I open the database connection on login.java and how to check with database whether the user enters the right username and password?

Is it possible to do something like WebView#loadUrl("http://10.0.0.2/ index.html") with service acting as local http server? Where would one start? Will I need at least partial http server implementation that would listen on the socket?

I have a web service running on my local machine, and I used IP address 10.0.2.2 to connect from the emulator to that web service, but when I try that on a Nexus One connected via USB, I get a timeout. Is there a way to access my machine from a real phone like I can from an emulator?

My activity needs to communicate with a java server located on my dev machine. Actually, using the emulator, I can access the server socket via the special 10.0.2.2 address. Now I'd like to test my app on my phone connected via usb, but it seems like I can't use 10.0.2.2 to access my dev machine localhost anymore. Naturally using a wifi router and a proper lan addressing does the trick, but I need to use usb connection instead. Any hint ?
1. Emulator-based scenario: standard java server running on my pc @localhost:15000 android java client running on my emulator. When the android app needs to contact the server it uses 10.0.2.2:15000 like specified here. Everything works fine.
2. Proper wifi scenario with physical connected device: standard java server running on my pc @192.168.1.10:15000. android java client running on my device with 192.168.1.11 address assigned. When the android app needs to contact the server it uses 192.168.1.10:15000 and everything works fine too.
3. Desired scenario: standard java server running on my pc @localhost:15000. android java client running on my device connected via usb cable. No network is active. When the android app needs to contact the server it tries to connect to 10.0.2.2:15000 but instead an exception is thrown (Network unreachable). It seems like special address 10.0.2.2 works only for emulator instances. I just wonder if in the adb/adt suite there's a way to access pc address from the device connected via usb cable.

I came across an interesting issue when testing android 2.2.
My testing was to use webview api,webview.loadUrl(url);
If url is from any public domain, ex, www.google.com, the web content is rendered very well.
[url]
If url is from local host, ex, tomcat with port 8080, the web content is rendered as well.
[url]
But if url is from other port, ex, websphere with port 9080, the web content is not rendered.
[url]
There is no exception thrown, and it shows blank on the emulator.
Is there any setting needed for different port?

I had a weird issue that has sprung up twice now with making phone calls and I wanted to see if anyone else was experiencing the same thing. Visually everything looks like it is functional with my phone service on the phone. I have bars, nothing out of the ordinary. However, I can't make any outbound calls either through my contacts or by manually dialing. I the number pad and it makes the response noise but doesn't actually type the number. In contacts, I hit call and the same thing happens. The fix I have found is just to soft boot the phone. Now I hear you all saying "No big deal, just restart." Yeah, it is no big deal unless I have to make a call in an emergency say calling 911 or things of that nature. Waiting for 5 minutes for my phone to reboot in an emergency can cost lives. I know I am being a little dramatic, but c'mon, at the end of the day, it is a phone and it is having trouble making calls.

I own a Samsung Galaxy S SGH-i896 and I decided to try and put on Cognition for a test, but before that, I did a android backup using ROM Manager. Now I thought this would save me in any situation...
So I flashed it over to Cognition, and it refused to connect to Rogers (as I expected) however, when I went to restore back, I would still get the AT&T start up, and the video was replaced by text that said "Android" in a weird font. I managed to flash it back to a stock AT&T ROM which worked well, but still wouldn't connect to the Rogers network.
I had tried to get into the ClockworkMod Restore Screen which I did finally get. I wiped all user data and cache, and restored from my backup...
Only to find my AT&T boot screen still there instead of the i896 screen and Rogers screen which would usually show. What can I do about this issue? Is there some kind of firmware or ROM from Rogers I need? I have a Rogers Stock firmware but that didn't seem to work either

I'm using ThreadSafeClientConnManager to manage a pool of client connections, because my application has several threads, which are simultaneously connecting to a webserver.
Abstract sample code:
CODE:..............
Now lets say on of this threads is downloading a large file, but then the user of my application is switching to another activity/screen. Therefor the file is needless and I'd like to abort this download connection.
In ThreadSafeClientConnManager I found this method: public ClientConnectionRequest requestConnection (HttpRoute route, Object state) Returns a new ClientConnectionRequest, from which a ManagedClientConnection can be obtained or the request can be aborted.
So far I've been using:
CODE:.........
Now from what I understand, I've to use:
httpclient.getConnectionManager().requestConnection(HttpRoute route, Object state);
And that's the point where I'm stuck. I assume that for the route I can just use new HttpRoute(new HttpHost("10.0.0.1")) or whatever my server is, but what to put in for Object state?
And second, as soon as I've the ClientConnectionManager I can call getConnection(long timeout, TimeUnit tunit). But then from there, how I do I execute my HttpGet httpRequest = new HttpGet(URL_TO_FILE); as I did before with HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);?
I've been gone through the documentation and tried out quite a few different things, but I wasn't able to obtain a working solution. Therefor any suggestions and/or code examples are more than welcome.

I'm coding a very basic FTP client on top of my application and I have 2 activities. The first one is the file explorer and the second one is the image viewer. Once I click on the image filename on the explorer, I want to pass the connection to the other activity to handle extra stuff. Basically, I want to keep the same org.apache.commons.net.ftp.FTPClient object (which handles the connection) alive in-between the 2 activities. I know I can't pass an object inside an intent so I don't know what my best bets are.
