In my Android app I need to extract data from a xml file (the file will have less than 2000 lines). I have no experience with XML parsing, so I don't know what the best approach is. DOM parser is perhaps not a good option, because I am on a mobile device. On the other hand with SAX I would probably end with more complicated code. What would you recommend?

I have created a class with 3 sub classes in Java. The 3 sub classes contain variables to store information from my XML document. I am able to store in the first two for there are only single instances of the data in the XML. The third class contains variables that repeat multiple times. I want to store an object of "third class" objects. I also have a SAX parser class. I am doing this within an Android environment (1.6).
Does this make enough sense without displaying any code?

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 there any class generators to process web services in Android/Java? I may have to write my own to generate classes against WSDL but I'm trying not to. Also is there one for REST services as well?
If not providing me with discovery service suggestions like disco/wsdl are good enough.
I have a doubt in XML parsing. I'm parsing a XML file. That XML file contains more than 14000 lines. I'm fetching 15 tag in that xml file. It is taking more than 7 times to fetch. Because 14000 lines * 15 tag. That much time it is taking. Any idea for this to reduce time. Or give some other coding to fetch xml data easily. No I'm using RSS Reader to fetch data as like in Java.
View 6 Replies View RelatedI currently building an android apps that retrieve data from a distant Web service and I search an efficient way to bind data form XML to ListView. I already use CursorAdapter and i search on the web for an "XmlAdapter". I read on Google IO topic "Coding for Life - Battery Life, That Is" (http://code.google.com/events/io/sessions/ CodingLifeBatteryLife.html) that is more efficient to use "stream parser" instead of "tree parser" but I don't find the way to build a class that implement ListAdapter because of stream parser can't navigate backward so I don't understand how implement method that use "position" parameter (How retrieve data before current XML Parser position?).
View 8 Replies View RelatedI am having one xml file and i want to parse it to get Student-ids and student-names only.
CODE:..........
My Problem:
When i am parsing the XML file using the above code, i am getting both the IDs(i.e. student-id, degree-id), so Using Pull-parser, what way i should parse the XML file to get list of only Student-id ?
I am having a problem where my XML files are slow to load and don't finish downloading before they start to be parsed which throws an xml not well formatted exception from my parser showing that the file downloaded incompletely. The complete error from logcat is "ERROR/Error(323): errororg.apache.harmony.xml.ExpatParser$ParseException: At line 10, column 46: not well-formed (invalid token)" I know the xml file is correct because sometimes it will work and I can also pull it up in my browser and look at it.
What would be the best way to make the parser wait for the InputSource before continuing on and parsing the xml data? The code below is the code I use to get the file and parse it.
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
GradeHandler gradeHandler = new GradeHandler();
xr.setContentHandler(gradeHandler);
URL url = new URL("https://url/to/xml/file");
HttpsURLConnection ucon = (HttpsURLConnection)url.openConnection();
ucon.setHostnameVerifier(new AllowAllHostnameVerifier());
xr.parse(new InputSource(new BufferedInputStream(ucon.getInputStream())));

View 1 Replies View RelatedI am trying to inject a long text entry into a SQLite database, in a TEXT field. This text has new lines in it (i.e. it spans multiple paragraphs). I can get the new lines to show up if I do the INSERT manually:
INSERT INTO "LOGENTRY" VALUES(5,40,'PLACE','line1
line2
line4
',1283990533315,'4A','TEXT','',NULL);
but if I have the equivalent text in a CSV file and attempt to .import it into the table, I get an error that it's expecting more columns than exist (as soon as the new line is encountered, the program assumes it's the end of the input and thus it's missing columns). Is this possible? Or is the only way to manually do each INSERT?

I have been at this for hours, but to no avail. I have been trying to root my GS2 with CF Root, but I can not get the tar file, instead, I see a zImage file. I am not extracting the tar to get the zImage. The zImage is what is there originally. I have tried multiple sources of CF Root, but get the same problem.
Edit: Figured it out, nvm

If not, anyone have a stock 2.1 build.prop file they can Email me so I dont have to SBF and loose everything I have setup now?

Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?
As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?
Is any SDK version which support Windows 2000? r05 doesn't - I found that android-sdk-windows oolsemulator.exe imports from WS2_32.dll functions freeaddrinfo, getaddrinfo and getnameinfo which missed from this library.
View 1 Replies View RelatedI 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!
Is there any way to access the value (any constants) from Android.mk file to my java file.
