Android :: Make SAX Parser Wait For File To Finish Downloading Before Parsing?
Sep 20, 2010
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())));

I have one activity call a camera view activity, and in the onActivityResult, I have it start that activity again with different parameters. Android doesn't seem to like that, and gives me an error that the camera is not available if I start it right after it returns. I tried just waiting a few seconds, but this doesn't seem to work on all phones, and it sometimes crashes. Is there some way to wait until that activity finishes properly, and gives up all resources?

I am trying to parse a RSS2.0 feed, obtained from a remote server, on my Android device using XML Pull Parser.
get a parser instance and set input,encoding
XmlPullParser parser = Xml.newPullParser();
parser.setInput(getInputStream(), null);
I am getting invalid token exceptions after a few items have been parsed:
Error parsing document. (position:line
-1, column -1) caused by: org.apache.harmony.xml.ExpatParser$ParseException:
At line 158, column 25: not
well-formed (invalid token)
Strangely, when I download the feed XML on the device, bundle it inside the raw folder and then run the same code. Everything works fine. What could be the problem here? How do I validate the XML before I parse it on device?

I am developing an android project. I am using dom parser to parse the xml file. Issue is my xml file contains HTML numbers like ½ (semicolon will come in the end of every char code) for example <quote>We "love" our nation</quote> which is nothing but <quot>We "love" our nation</quote> I am not able to parse this HTML number in dom parse, when I try to get the node value, I am getting null. Can anyone tel me how to parse this HTML character codes? or How to convert this HTML char code as either text char code or unicode char set in my xml feed?

So I've got to parse ugly files that contain nested tags like <p>blah<strong>lah</strong>blah</p> The nested tags are defined and I don't care about them. But they make XmlPullParser fail: XmlPullParser parser = XmlPullParserFactory.newInstance().newPullParser();parser.setInput(some_reader)Code...

I can't use shutdown() and awaitTermination() because it is possible new tasks will be added to the ThreadPoolExecutor while it is waiting.
So I'm looking for a way to wait until the ThreadPoolExecutor has emptied it's queue and finished all of it's tasks without stopping new tasks from being added before that point.
If it makes any difference, this is for Android.

I'm using "AppBrain App Market". I have installed a bunch of apps, but some get stuck and just stay in "Downloading" state. They just never finish downloading. I see the progress bar "barbershop pole" style but there is no sign of progress. Some are new installations, some are updates.
This is despite the fact that some apps HAVE successfully downloaded and installed. What could the problem be? How do I resolve this?
Cancelling the download and restarting the download resolved the problem once. (Downloads / click on neverending download item, Cancel Download)
But if the button series is (Downloads / click on neverending download item, *Installing*). Then the Installing button is greyed out then I'm stuck.
This thread did not provide any solutions: Market Apps Finish Downloading but Won't Install

I've had this issue since the 2.2 leaks (2.2.9-2.3.15 and now with RubiX) and have finally gotten tired of it. When downloading apps or updates from the market, 1/2 the time it'll finish downloading but then won't install. It just hangs there at 100% and nothing happens no matter how long I leave it there. I have to cancel download and then re-download, sometimes multiple times, before it'll install it automatically. This happens with every app, and while I do eventually get everything install, it will still very annoying. Does anyone else have this issue?

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?

With this sample code, the activity is told to finish, but continues execution afterwards and displays the message. I'm trying to understand why this happens. The only fix I can think of is to place 'return' after finish.
public void someMethod() {
if( valueIsTrue) {
startActivity(new Intent(this, NewActivity.class));
CurrentActitivy.this.finish();
// return; // if uncommented, Toast doesn't show
}
Toast.maketext(this, "Some message", Toast.LENGTH_SHORT).show();}

I have to download a file and I'm using this code, which is basically an AsyncTask that is meant to update a progress bar. But, since I don't know what's the file size I've been having to use the spinner progress bar. So, how can I get the file size before start downloading it so that I can use a normal progress bar?

I have an application that I'd like to add auto-update functionality (its not in the marketplace). I have all the code in place that would check to see if there is an update available and then i call something like this: Intent intent = new Intent(Intent.ACTION_VIEW ,Uri.parse(Configuration.APK_URL)); c.startActivity(intent); which starts downloading the file, although is there a way that I can programatically tell it to "open" the file to begin the installation process without the user having to go to the downloads and clicking on it?

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?
