[android-beginners] Best practice for AsyncTask when screen is rotated
So I have an AsyncTask that is being used to perform a simple http request in the background. As a constructor argument to the task, I pass a reference to the current activity and use methods on the activity to manipulate which gui elements are shown in the onPreExecute(), and onPostExecute() method calls. Now due to the fact that android tears down and rebuilds an activity when the screen is rotated, the UI is not properly updated based upon the AsyncTask as the refernce to the activity is no longer valid. Its not really clear to me how to handle this case. I'm also worried that this could lead to memory leaks. Any suggestions etc. would be appreciated. thanks, Dave --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: 500kb OPML parsing issues
Use a SAX parser to parse the XML, see http://developer.android.com/reference/javax/xml/parsers/SAXParser.html.

[android-beginners] Best practice for polling a remote resource periodically
Hi All, I'm starting to write an app that will periodically poll an HTTP resource and use the data to update a View. My initial thought process on how this will work is that on application startup, my activity will spawn a worker thread that will maintain an object model of the data and update it as necessary. Ideally this thread would publish back to the UI thread that the data has changed and the UI thread would read the object model and update the view. I'm not too familiar with Android's architecture to support threading and messaging between threads, so I was wondering if there was a good up to date tutorial etc. that someone could point me to. Thanks, Dave ps. In the past I've used AsyncTask but i don't think it will meet my requirements as the UI thread would need to maintain a timer to kick off an AsyncTask. Ideally I'd like to isolate these two parts of the application as much as possible. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: XML Parser
XML Pull Parser is great. See http://developer.android.com/reference/org/xmlpull/v1/package-summary.html. Gives you the streaming benefits of SAX but is much easier to work with imo.

[android-beginners] Re: Mulittouch in android?
Short answer is that the device driver supports it but the functionality is not exposed in the Java API. The hero most likely uses a hack see: http://groups.google.com/group/android-platform/browse_thread/thread/209b512a9fdf7367?pli=1 for the gruesome details.
