Android :: What Does The Application Modularity Mean In Official Document?
Feb 6, 2010
there is an article in android document(Dev Guide/Publishing/Signing Your Applications/Signing Strategies)
"Application modularity - The Android system allows applications that are signed by the same certificate to run in the same process, if the applications so requests, so that the system treats them as a single application. In this way you can deploy your application in modules, and users can update each of the modules independently if needed."
in this article, what does "module" mean? is it an apk or something else? and if module is apk, how to install & update an apk by main apk without user operation?

I want to read a Open Office Document spreadsheet (.ods file) from my android application. I need to basically loop through the first two columns & store them in a SQLite database. I am able to do this by reading a regular text file stored in res/raw using the following code:
InputStream is = context.getResources().openRawResource(R.raw.my_text_file);
But no clue how to do the same for an .ods file. I searched through SOF & found a reference to jOpenDocument . But they talk about libraries that are not part of the android SDK & I don't know what to do with these.

I am developing an android application at the moment, and i'm facing a problem that i have no idea how to solve. My application communicates with a Tomcat Server, and i'm using ObjectOutputStream to send a Document object to my application from my servlet. There fore, i'm importing org.w3c.dom to my project. The problem i'm facing is, that I can't read the Document object with ObjectInputStream on my android device. I'm getting the following exception.
CODE:..................
I can send and recieve any object i want without any problem, but when I try to send an object refered to the com.w3c.dom package I get this exception.

I can't figure out how to attach a document in the Gmail app but it only gives me the option to attach photos from my gallery and not anything else, for example an excel spreadsheet or pdf on my sd card.

My Android main application will consist in a main program, with a few pre-installed modules.Then I want to offer different modules later, best would be as separate files. Modules like: location, weather, agenda.How would you accomplish this?I want to keep in the database the modules that are installed/present. So I must put sometimes the modules into database, maybe by detecting if there are present at launch time. The main app will work based on these modules.How can I build these modules as separate files? They won't be an entry point in my application. So they must not be an application in the navigation menu.

Just got a Nexus One a couple of weeks ago and was somewhat disappointed that there wasn't an official Yahoo Messenger app (everyone I know uses it). Anyway, I just found the official Yahoo Messenger just showed up in the Market. Yahoo Search and Mail are there as well but I'm not sure if they are new or not. Yahoo! Messenger for Android

Yup, its been released. Its free and you can get it on the the market. Its decent. But I would much rather prefer a port of the iphone version. The biggest letdown was no implementation of chat.

The documentation shows that you can directly link to your app on Android Market place. But every HTTP url I attempted, I am getting a page not found error. I am wondering if there is something wrong with the documentation or is there a rules change where we can directly link to apps we created. if that is the case, why is this documentation still exist pointing to incorrect information?

I'm getting a "SAXParseException: Unexpected end of document" error when trying to parse an xml document on android. The document in question is from the google weather api, but it seems to throw the same error regardless of the xml file in question (as long as the xml is valid) so I suspect it's a problem with my approach, rather than the xml. This is being done as a learning exercise, so I've probably (hopefully) overlooked something obvious. I've run the xml through an online validator, and it comes back as being well formed. (Can't tell me if it's valid as I don't have a DTD, but I dont think I need the DTD to parse the xml). This is the code that I'm using to try and parse the file:
private void refreshForecast() URL url;
try { url = new URL( "http://192.168.1.66:8000/google4.xml");
URLConnection connection = url.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection)connection;
int responseCode = httpConnection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
InputStream in = httpConnection.getInputStream();
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
// falls over here parsing the xml.Document dom = db.parse(in);
} } catch (ManyExceptions e) { ....
} A cutdown version of the xml that produces the error is:
<?xml version="1.0"?>
<xml_api_reply version="1">
<weather>
<forecast_information>
<city>Hamilton</city>
</forecast_information>
</weather>
</xml_api_reply>
The stacktrace is:

In the interest of brevity, I've not included the original xml, but it's just the standard weather xml from googles feed. I've also tried a few completely different xml files, (including the sample from http://www.ibm.com/developerworks/xml/library/x-android/) and they all give the same error. (They also all validate as well formed when I run them through an online xml validator). This makes me think that it's not a problem with the xml, but rather with how I'm trying to feed it into the parser.

I am trying to parse an HTML document that is missing an end tag on one of the elements (input tag). Anyone know how to get the parser to ignore that it doesn't have an end tag and just read an attribute value?
DocumentBuilderFactory dbf DocumentBuilderFactory.new Instance(); Document Builder builder = dbf.newDocumentBuilder(); Document dom = builder.parse(url.openStream()); //ERROR HERE Error: 01-28 21:34:38.384: WARN/System.err(12108):org.xml.sax.SAXParseException: expected: /input read: div (position:END_TAG </div>@21:10 in java.io.InputStreamReader@432749f8)

This should be trivial, but for whatever reason I can't find any easy way to do this. Coming from C# where this is a 1 line call, I don't understand why Java makes this so complicated, and on top of that android leaves even that out of its libraries. Anyway all I want to do is write an
org.w3c.dom.Document
that I have populated to a xml file. It should be as easy as opening a stream and writing document.toString(). But that doesn't work. My hope is I'm just missing something.

I am trying to retrieve a XML document from web service. I am passing a soap object with a token implementing the OAuth concept and retrieving the data. But the data does not turn out to be in XML format. It contains a curly braces in the place of start tag and semicolons when it ends. Is there any way to retrieve the document in XML format as such?

I did a quick search and couldn't find anything similar to this thread. I am taking a four day train trip across the country (The US) in August and I was wondering what apps would be best to document this? My ideal goal would be to have my route tracked, perhaps Google Maps Integration somehow, and also have pictures/text messages from along the way put onto the map wherever they were taken/written. I would like this to be viewable by friends/family online as the trip is happening.If I can't get the route tracked, that's fine, but I would like someway to display the pictures/texts from along the trip.What App or combination of apps would you guys recommend I use to accomplish this?I am familiar with WordPress and have used the Android Wordpress App a bit, but not too in depth. Would I be able to use this? Or is there a better way?Oh, and one more thing, unrelated. I noticed some apps (Google Voice for example) listed "Services that cost you money" as one thing they have access too. What exactly does this mean?

I created an application which reads an xml document from url address. Lately the logic has been modified and now instead of receiving the url address of the XML document I receive the document content itself As mentioned the variable String content is not an url but an XML document so I have to pass this content to XMLReader. Currently the line xr.parse(content); doesn't work correctly as the value 'content' is not an url anymore. Does anyone know how should the method be modified in order to parse the XML content instead of trying to parse the content from the given url?

I'm parsing a very simple XML schema with a SAX parser in Android. An example file would be
<Lists>
<List name="foo">
<Note title="note 1" .../>
<Note title="note 2" .../>
</List>
<List name="bar">
<Note title="note 3" .../>
</List>
</Lists> the represents more note data as attributes that aren't important to question.I use a SAX parser to parse the document and only implement the startElement and 'endElement' methods of the HandlerBase to handle Note and List nodes.However, In some cases the files can be very large and take some time to process. I'd like to be able to abort the parsing process at any time (i.e. user presses cancel button).The best way I've come up with is to throw an exception from my startElement method when certain conditions are met (i.e. boolean stopParsing is true).Is there a better way to do this?I've always used DOM style parsers, so I don't fully understand the SAX parser.One final note, I'm running this on Android, so I will have the Parser running on a worker thread to keep the UI responsive. If you know how I can kill the thread safely while the parser is running that would answer my question as well.
