View 2 Replies View RelatedI'm facing an annoying problem here. My application is connected to a server that sends some data from time to time. It's some kind of eventing server. In order to receive data, I'm connecting to the server with an HttpURLConnection, retrieve the response InputStream and loop on it with the read method. The connection is always open. The distant server is cutting the connection every 5 minutes (for test purpose). When connection is closed, my application has to reconnect again. We detect a Connection Reset by Peer exception when the server closes the connection. The problem is that most of the time, I never receive the Connection Reset by Peer exception. So my application can't know that is has to reconnect and it's stucked on the read instruction. The InputStream.Read() method shouldn't always raise an exception if the connection is closed? What can I do to always detect Connection Reset by Peer exception?
View 15 Replies View RelatedAn 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'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?
So, first, here's what happened. Did a factory reset of my phone. When it came back up and I went to activate it, no data connection, unable to make phone calls. After 2 hours on the phone with VZW tech support, I can make calls, but have no data connection. They are sending me a "new" one. The concensus of the VZW tech and myself, problem with my phone. 2 days later, my wife resets her phone because of memory usage issues (she had to much on it). Same exact thing happened to her. Being the fiesty woman that she is she is going to a VZW store today to raise holy hell and throughorly degrade the poor rep that she is going to talk to, to get some answers. My question to all my fine fellow Eris users, have you seen this before? If in our position, do we deserve a new phone, and not an eris? Will this happen with a replacement eris due to a fault in the 2.1 update?

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.
Whenever a application needs internet and connection fails, I get a message dialog

Why a Froyo factory reset really isn't (plus, a fix for upgrade issues) | Android Central Its in reference to the X but I am going to factory reset tonight and see what happens."If you're one of those folks who is less than pleased with your Droid X after the Froyo update, this one's for you. Android Central Forums member Fabrian was at wit's end, and even talked of ditching his X (blasphemy!) because of the random bugs, general weirdness, and plain old unsatisfactory performance of his unit since the update.His last-ditch effort and ingenuity seems to have paid off. The secret? He has completely disabled the Froyo feature that restores data from previous installs. It's really just a matter of turning off the automatic restore feature before logging back into your Google account. It's a little odd that "Automatic Restore" is still checked by default, even when "Back up my data" isn't, but there you go.The method isn't too painful and does require one more factory reset, but the payoff appears to be a much smoother experience. Makes sense, too restoring data from Eclair to Froyo probably isn't a very good idea even if it is convenient.
We've verified it here, a hard reset in Froyo isn't really a hard reset, as things come back by themselves. Follow Fabrian's instructions, and you will have a pristine Froyo installation on your Droid X (or Nexus One -- Sense on Froyo has no setting for this that we could find). Any troublemaking leftovers will be no more, and won't get downloaded and installed automatically again. If you're being plagued with myriad tiny bugs in your Droid X after the update, give it a try! [Android Central Forums] Thanks Fabrian, nice sleuthing!"
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.

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!
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?
