Android :: Bizarre Conversion To Dalvik Format Error Caused By Google Chrome APK File Lock
Jul 20, 2010I have a small test Android Project used to test the MediaPlayer class.
For this project, usually after a few builds, the compiler gives this exception:
Conversion to Dalvik format failed with error 1
I've narrowed this down to Google Chrome locking the generated .apk file (in /bin). So, the build is unable to remove that APK to rebuild.
Sure enough, quitting Chrome, solves the issue.
This is bizarre, isn't it! Why would Google Chrome be grabbing a lock on that file?
I have never had this error with any of my other projects.
Android :: How To Layout Image Buttons In A Grid View From Xml Layout File
Jan 23, 2009Is it possible to build a GridView object in XML with 3 columns and 4 rows of Image buttons? It doesn't seem to have similar containment relationship like LinearLayout or RelativeLayout viewgroups.

Android :: SAXParser And Malformed XML
Aug 14, 2010I am using a saxparser to read RSS XML from the web and populate listviews. Everything works fine until I come across malformed XML, usually encoding related, and my reader falls over. I have changed it so that it gets as many items parsed and populated before falling over (by default if it finds a malformed XML, then it will give up and return an empty collection). The problem is, the next time I try and view that feed (or any other feed), it still has the contents after the malformed bit hanging around.
For example, the first time it now shows all the items upto the malformed item, if I refresh, it will only show items after, refresh again, it will show items upto and so forth. The weird thing is, I create a new instances of everything every time. So I don't understand why stuff is handing around. It's like there is some read pointer, or connection that needs to be closed and reset, but I can't for the life of me work out what or where!
My GetFeed method:
private RSSFeed getFeed(String urlToRssFeed) {
SAXParserFactory factory;
SAXParser parser; XMLReader xmlreader;
URL url; InputSource is;
try { url = new URL(urlToRssFeed);
factory = SAXParserFactory.newInstance();
factory.setValidating(false);
parser = factory.newSAXParser();
xmlreader = parser.getXMLReader();
xmlreader.setContentHandler(m_FeedHandler);
is = new InputSource(url.openStream());
xmlreader.parse(is); m_ErrorCode = NOERROR;
} catch (SAXParseException e) { e.printStackTrace();
m_ErrorCode = XMLFORMAT;
} catch (Exception e) { e.printStackTrace();
m_ErrorCode = CONNECTION;
} finally { is = null;
url = null; parser = null; factory = null;
return m_FeedHandler.getFeed();
//May be complete, partial or empty.
} }

Android :: How To Use XML File To Specify Layout?
May 13, 2010I've been trying to create a Compound Control in Android 1.5 (as described here) but haven't been able to find any good examples on how to do this using an XML file to specify a layout. Create Custom Component based on LinearLayout, declaring layout in XMLI'm fine with creating an Activity and then loading an xml file using the following in the constructor:
setContentView(R.layout.main);
However, I want to do this in subclass of LinearLayout - so I can use this compound component in other XML layouts. Something along the lines of:
public class CustomView extends LinearLayout
{ public CustomView(Context context) {
super(context);
setupView();
} public CustomView(Context context, AttributeSet attrs)
{ super(context, attrs);
setupView();
} public void setupView() {
setContentView(R.layout.custom);
// Not possible } }
What is the correct way of going about doing this?

Any idea why they used this curly-brace syntax instead of something standard like XML?
Android :: Dynamic Loading Of Complete Layout File
Jul 1, 2010I'm dealing with a problem you guys might not have faced earlier. I'm having a use-case in my Android application where the actual screen that I want to show to user is not stored in any layout file of my application. The layout of the of the screen is designed by server in this case, based on selection made by user on first screen.
Let me elaborate here,
1st Screen : List of check box with different biller names. (Imagine I've selected 2 billers from this screen)
2nd Screen : (The screen that server has decided how it should look like)
* Header,
* 1st Biller name (Label)
* Amount for 1st Biller TextBox
* Image (a Separator image)
* 2st Biller name (Label)
* Amount for 2st Biller TextBox.
* Here there can be a checbox/radio/another TextBox anything.
* Image (a Separator image)
* Button (to submit above form back to server)
I hope makes some sense in what I'm planning to design. The current issues I'm dealing with are as below.
1). How to draw this dynamic widgets?
2). How to fetch user Inputs from this dynamically created widgets?

Android : Create A Layout Using The Xml File And Code Within The Activity?
Jul 9, 2010I'm trying to create a simple text based game in which I ask a question based on a movie. The list of movie's is in a text file which I've included in res/raw. So basically I want to have a default string, say "Who acted in", followed by the name of the movie. Could I have the first string (along with a submit button etc) in my res/layout/main.xml file, and follow that with the movies name, after I've extracted it from the text file in my activity, or does the layout have to be defined in one place only?
