I am trying to implement a robust RSS/Atom reader for android, and since Xerces won't compile I am struggling to find an alternative. I am using org.xmlpull.v1.sax2.Driver(), however this just wraps a DOM parser with SAX callbacks. Is there anything comparable to Xerces on Android?

View 9 Replies View RelatedThe LocationManager API in android seems like it's a bit of a pain to use for an application that only needs an occasional and rough approximation of the user's location.The app I'm working on isn't really a location app per se, but it does need to get the user's location in order to display a list of nearby businesses. It doesn't need to worry about if the user is moving around or anything like that.Show the user a list of nearby locations.Preload the user's location so that by the time I need it in Activity X, it will be available. Don't particularly care about accuracy or frequency of update. Just grabbing one location is sufficient as long as it's not way off. Maybe if I want to be fancy I'll update the location once every few mins or so, but it's not a huge priority.
Work for any device as long as it has either a GPS or a Network Location provider.
I am trying to find a News Reader and find that most of them seem to rely on feeds from Google Reader and seem not to recognise UK based feeds (or at least I cannot find the same feeds that I used on my iPhone).
View 11 Replies View RelatedI'm writing a bitmap editor where I use the Command Pattern to represent actions that will transform the document. I keep all the commands executed so far in a list and, to implement undo, I restore the document to its initial state and then replay all but the last command.
I would like my undo/redo system to have the following feature: When the user closes the editor and returns, the document, including the available undo and redo commands, should be restored to the state it was in when the user left.
I'm implementing this for Android where your application can be given very little notice before it will be cleared from memory if e.g. the user gets a phone call. Also, some of my commands are e.g. a list of all the x,y co-ord the user painted on so these might take a few moments to save to disk.
My current idea is as follows:
When a new action is performed, the command object is added to a list S for commands that need to be saved to disk.
A background thread is used that will continually take commands from list S and save them to disk. The postfix of the filenames used will be numbered in sequence. For example, if the user filled the screen then drew 2 circles, the command files might be called FillCommand1.cmd, DrawCircleCommand2.cmd, DrawCircleCommand3.cmd.
Periodically, we save a "checkpoint" command whose purpose is to store the full document state so that, even if one of the .cmd files is corrupted, we can restore a recent version of the document.
When the user exits the app, the background thread attempts to finish up saving all the commands it can (but it might get killed).
On startup, we look for the most recent .cmd file that represents a checkpoint that we can load successfully. All the .cmd files we can load after this (i.e. some files might be corrupt) go in the redo command list, all the .cmd files we can load between the first checkpoint loaded and the oldest checkpoint we can load go in the undo list.
I want the undo limit to be about 20 or 30 commands back so I need extra logic for discarding commands, deleting .cmd files and I've got to worry about multi-threading behaviour. This system seems pretty complex and will need a lot of testing to make sure it doesn't go wrong.
Is there anything in Java or Android than can help make this easier? Am I reinventing the wheel anywhere? Maybe a database would be better?
In Android, you need to implement the following Activity methods so your application can be restored to its previous state if the OS decides to destroy then recreate your activity:
public void onSaveInstanceState(Bundle savedInstanceState)
public void onRestoreInstanceState(Bundle savedInstanceState)
The examples I've seen of implementing these methods is to use put/getBoolean, put/getInt etc. on the Bundle object (i.e. primitive objects only) to save the application state. This seems hugely error prone way to save your state for a start and I cannot see how this scales to storing complex objects without writing lots of code.
What options do I have for storing/restoring state in a robust and easy to implement fashion?
In case it's important, my application (a game) needs to store about 50 objects, which each store maybe 5 float variables and some store references to other objects. I don't particularly want to have to write save/restore methods for every class and subclass (maybe about 15 of these) I use. It would be ideal if I could just stick all my state relevant objects in an object called "state" and then just call save/load on "state" to handle everything.
Is using Java serialization an option? I've heard it's very slow, but is that a problem for save/restoring? Could I just write my data to the SD card? To a database?

Two simple questions
1. What is your favorite E-Book reading app
2. Why is it your favorite?
I am going on vacation in a couple weeks and would love to take some books with me, with out having to carry books with me lol.A good library of free books is appreciated, but I am not opposed to paying a reasonable price for good books.
I have a Telus HTC Desire and I'm trying to put Barnes Noble's ereader on it. When I go to the market and search either BN reader or Nook it comes up blank...it's supposed to be there. Is anyone else having this issue? Does anyone have the installer file?

View 6 Replies View RelatedMy mother recently indicated that she's considering being in the market for an ebook reader. However she is, bless her soul, firmly insistent on open format, DRM-free, and the ability to "really own" a book she's downloaded. She doesn't even want the potential for a Kindle-1984-type remote-wipe or an inability to move a book to another device later. (Yes, my mother has grown up to be a Free Software evangelist. I'm so proud of her. *sniff*)
Of course, she doesn't know the ebook market all that well, and frankly neither do I. She's considering the B&N Nook, but from what little I know it has the same lock-in problems as the Kindle.
So my question is, I suppose, two-fold:
1) Are there any ebook stores or services available for any device that don't treat customers are criminals waiting to happen, and use a DRM-free format without revocation ability? Are they bound to a given device, or are there any that work on an arbitrary Android device? A good ebook reader app or use of the open ePub format (for which I understand there are several readers available) is a plus here.
2) Of the various devices out there (both phone and non-phone), which make particularly good ebook readers? She has a decently large purse but it still wouldn't hold an iPad-sized device comfortably, but at the same time a 3-inch screen is not going to work for her eyes. (It barely works for mine.) What's a good device if that's your main interest? Any good/bad experiences here, or at least things to look for?
An ebook reader app that has an integrated (or anyway a very handy) dictionary or translation feature.
I'm tired of switching app and type the word when i should just hold on a word to directly access its meaning.

Does Froyo natively open PDFs or something? (On a related Adobe note, should I go ahead and install AIR now, in case I need it after Gingerbread comes out? I don't even know what it does, really, but apparently installing it *after* an OS update causes problems. Why Adobe can't just fix that issue, I have no idea.)
