[android-developers] AccountManager wrong password or account changed error
This is a reply to: http://groups.google.com/group/android-developers/browse_thread/thread/d66ff537b04ec9a8 (which is closed for replies). I had the same issue when trying to develop an app that authenticates with the Google Docs List API. My AccountManager.blockingGetAuthToken(account, AUTH_TOKEN_TYPE, true) call would cause a notification bar warning to appear that said something like Sign-in error... and then asked me to re-enter the password. The solution turned out to be correcting the AUTH_TOKEN_TYPE string. After I set it to writely (based on the table from http://code.google.com/apis/gdata/faq.html#clientlogin), everything worked. The table is copy-pasted below in case that page goes away: A service name is a brief string that the ClientLogin authentication system uses to identify a Google service.

[android-developers] View moves downwards after standby
Hi, I noticed that when my app is onscreen and the device goes into standby (black screen) and the device gets out of the standby the View (layout) will be moved a couple of centimeter downwards so that the last couple of centimeters of the View actually will fall offscreen.. The Activity itself is declared as being android:screenOrientation=portrait android:theme=@android:style/Theme.NoTitleBar.Fullscreen After some more in-depth research, or actually just looking at it, I noticed that the amount of movement (the height of it) actually looks a lot like the height that the statusnoticebar should take. Anyone ever experienced this and/or anyone got a solution for it ? Also how should I force a redraw of the whole screen when it comes out of the standby mode ? I tried placing a MainLayout.ForceLayout() in the onResume() method but that didnt work at all :( -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Retrieve android:versionName from Library Project
Ok, I did understand that no APK at all is created by the Project Library, it doesn't even get compiled, it does get compiled when the host project is compiled... But I don't get what you mean by it is to merge stuff into the parent project... I mean, you have to redeclare all used activities/services/whatever into the hosts-project manifest, by referencing the package name of the Project's Library components...

[android-developers] Versioning and common code-bases with Eclipse
Hi there, I'd like to bring out an app in the near future, so I was wondering how to support a couple of funcitonalities I have got used whilst developing for J2ME and iPhone - first the versioning. With J2ME (using NetBeans as IDE) I had the option to auto-increment the softwwares version every time I compiled it. I was wondering if something like this is available for Eclipse and if so how to use it ? - secondly a common code base. Is it possible to have a common code base for several projects ? For example I might have a game which actually uses the same code but needs different graphic resources. I'd hate to have a different project for every game/app and have to manually edit every project's source every time I want to submit a new code-change. Any solution for this ?

[android-developers] Question regarding drawable resources usage
Hi, I have made an app which I also would like to run on smaller screens, so I have read the documentation regarding supporting multiple screens. I noticed though that I actually didn't need a completely new layout, the only thing I needed were actually smaller images which are used within the layout. Because I haven't found anywhere in the documentation if that would be possible (so just placing couple of .png's within the drawable-ldpi directory and the underlying os will pick those instead of needing a whole new layout) I just decided to give it a try... So I resized couple of Images that needed to be resized, I placed them in the drawable-ldpi and then I started up the emulator (1.6 to start with) with a small screen. It actually worked ! But because I don't have a real small screen testing device now I was wondering if it's just the emulator which will display this correctly or if I can expect it from a real device as well ? Does anyone have any experience regarding this (so just replacing a couple of images instead of creating an ew layout) ? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Status bar leaves a black bar in my Fullscreen Activity !
Hi, I have a Fulscreen Activity (by using android:theme=@android:style/ Theme.NoTitleBar.Fullscreen). I noticed that when the device has gone into powersave mode (black screen) or when I have used the Home Button, and I get back in my Activity the whole Layout will have been moved downwards leaving a black bar of nothingness on top of the Activity :( The Activity Layout fills the screen precisely, so when this happens I am able (with the scrollball) to scroll my whole Layout upwards and downwards for the height of the aforementioned black bar (of death?)... At some point I noticed it looked like it was just as high as the stanbdard Android status bar, so I dismissed the Fullscreen from the Activity...

BUT, if you check out the HTC's developers site you will notice that the downloadable OS versions don't go any higher than 1.6... This means you will not be able to test 2.0, 2.1, or 2.2 with a ADP... U'r stuck with 1.0 to 1.6...

[android-developers] Re: Service unable to call Java Class Methods
First, you debug a Service the same way you debug anything else. You set breakpoints in the appropriate lifecycle methods, or in routines called from those methods. Done that... If I recall correctly, this works even if the Service is running in a different process, but you might need to enable debugging on the specific process via DDMS. Tried that, when my app is started in the DDMS it will show my app (myprojects.android.controlCenter) and, I guess, my service (myprojects.android.controlCenter:remote)... When I try to debug that it the DDMS will throw an error : No opened project found for myprojects.android.controlCenter:remote. Debug session failed ! You don't quite say what makes you think your method isn't being called. On the face of it, this would seem to mean simply that the code that calls it doesn't run. But later you talk about It just simply seems like the Service doesn't see the Logger class, but with nothing to indicate what that means or why it seems that way. Well I have logging to the System.err.println within the Logger class method which is being called, and it doesn't print to screen, so to me it seems like that method is not being called or executed... That's why I think the service doesn't see the Logger class : it cannot call it's method otherwise I would see that in my console because of the System.err.println() call within the called method... I do know the Logger class works, it is being called by other Activities and it prints happily everything it needs to print :D After a lot of debugging I guess this is the answer who might help me out : Note that you refer to it as a singleton, but that's only meaningful within a process. It seems the Service will make it's own Logger Singleton, which makes creating an architecture with (for example) a static management layer impossible... After all that static management class would be a singleton as well, but having the service being in another Process it will create it's own management class...

But later you talk about It just simply seems like the Service doesn't see the Logger class, but with nothing to indicate what that means or why it seems that way. There are four ways that this could happen. I doubt any of them actually apply to your situation, but it's worth listing: 1) The class isn't found at compile time. The code won't compile, you won't actually be running the current code. 2) The class isn't found at run time. Somehow it didn't get packaged up in the .apk. Since the classpath would be the same for both the Service and any Activities, you'd see the same ClassNotFound exception at runtime. 3) The class is found, but gets an error while loading. This would give a ClassNotFoundError. The class will be successfully loaded once per process/.apk pair, so you'd normally get the problem for both, if in the same process, unless there's some initialization that happens between that allows it to load the second time. If in separate processes, if there's a dependency on things happening before the class loads, it might load in one process and not the other. Note that you refer to it as a singleton, but that's only meaningful within a process. 4) The class is found, but loads, but the method itself is not found. This gets a MethodNotFoundException or other exception at runtime, depending on the exact behavior of the VM; I'm not sure it's fully specified. This situation only happens if code is successfully compiled against one version of the class, but finds a different version at runtime without the appropriate method. This would be similar to case #1 in origins. It is seldom found in practice, but usually doing a clean of the project and rebuilding will resolve it -- often by turning into case #1. Anyway, your main solution is to actually debug the problem. Step through a call to your logger and see what happens and what doesn't happen. You should actually know if your Service is running in another process -- you'd have to set it up that way in the manifest. Just because you're using IPC doesn't mean it's in a separate process -- it just means you could set it up that way and the communication would still work.

But later you talk about It just simply seems like the Service doesn't see the Logger class, but with nothing to indicate what that means or why it seems that way. There are four ways that this could happen. I doubt any of them actually apply to your situation, but it's worth listing: 1) The class isn't found at compile time. The code won't compile, you won't actually be running the current code. 2) The class isn't found at run time. Somehow it didn't get packaged up in the .apk. Since the classpath would be the same for both the Service and any Activities, you'd see the same ClassNotFound exception at runtime. 3) The class is found, but gets an error while loading. This would give a ClassNotFoundError. The class will be successfully loaded once per process/.apk pair, so you'd normally get the problem for both, if in the same process, unless there's some initialization that happens between that allows it to load the second time. If in separate processes, if there's a dependency on things happening before the class loads, it might load in one process and not the other. Note that you refer to it as a singleton, but that's only meaningful within a process. 4) The class is found, but loads, but the method itself is not found. This gets a MethodNotFoundException or other exception at runtime, depending on the exact behavior of the VM; I'm not sure it's fully specified. This situation only happens if code is successfully compiled against one version of the class, but finds a different version at runtime without the appropriate method. This would be similar to case #1 in origins. It is seldom found in practice, but usually doing a clean of the project and rebuilding will resolve it -- often by turning into case #1. Anyway, your main solution is to actually debug the problem. Step through a call to your logger and see what happens and what doesn't happen. You should actually know if your Service is running in another process
[android-developers] Service unable to call Java Class Methods
Hi, I am using a Service to play some music. In the same project I have several Activity's but also some custom classes which are part of a framework, so nothing graphical. One of those (singleton) classes is a Logging class which send logs to my server. I noticed that even though I can call the classes methods in my service it actually won't be logging anything... In my specific example it's osmething like : Logger.getInstance().log(Whatever I want to Log); Obviously the getInstance is a static method so it can be accessed from anywhere within my project right away.. I was wondering though why this method for example isn't getting called ? Also how do I debug a Service ? Btw I am using of IPC from one of my Activities which gets bound to the service and can start/stop the music for example... Any help, hints, tips, or tricks are greatly appreciated ! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Service unable to call Java Class Methods
Actuall the LogCat doesn't show anything... It's not like I am getting any errors/exceptions... I have been using System.err.println in the Service, which print out just fine in Logcat... But, yes there is always a but :P, I don't want the service to write to the System.err but to my Logger class, which btw implements Console logging (to the System.err :P) and a http logger which simply sends a buffer of logs to my server... The class is imported : import myprojects.android.loggingModule.Logger; It just simply seems like the Service doesn't see the Logger class, they are in the same project, not specifically in the same Package though... Might it be that the Service is simply a independent Process itself with no ties to any other classes/objects ? On 22 jun, 15:47, Gyan gnanesh@gmail.com wrote: Can you paste the logcat trace?

[android-developers] Re: Service unable to call Java Class Methods
unfortunately using the complete path didn't make any difference at all :( Reflection, afaik, are handy if some method's/api's are missing and thus you can fall back on another implementation.. But I'm afraid in my case it would always fall back to the other implementation, thus never using my Logger class :( After all, I can check if it recognizes my class, but if it simply doesn't then I actually wouldn't have any use in calling an alternative or whatever...

[android-developers] Re: help on singleinstance launchmode
Actually,
to me it sounds it's behaving correctly...
If Activity B is standard then it might be re-used, so it's not
obliged to create a new Instance...
Thats what happens in ur case, first time it get's created, then you
go to activity A, then when you ask for Activity B the old activity
B is returned...
If you don't want that as a behaviour you might declare B as
singleInstance or even better singleTask...

[android-developers] Re: help on singleinstance launchmode
Btw, got this from documentation, concentrate on the last sentence :
Every time there's new intent for a standard activity, a new
instance of the class is created to respond to that intent. Each
instance handles a single intent. Similarly, a new instance of a
singleTop activity may also be created to handle a new intent.
However, if the target task already has an existing instance of the
activity at the top of its stack, that instance will receive the new
intent (in an onNewIntent() call); a new instance is not created.

I can make the header columns and data columns all line up perfectly if they're all in one big TableLayout, but how would I get the header to be outside of the scrollview yet also stay uniform and inline with the data columns? You'll need to set the sizes of every one of your columns -- in other words, use dimension resources instead of wrap_content for the width. If you use a RelativeLayout for the header and a RelativeLayout for the rows, you can then use those same dimensions and layout_marginLeft to have everything consistently line up. Or, use GridView.

[android-developers] Re: How can I use VideoView to streaming without buffering?
well most of the time buffering is just part of streaming... it's there so that a user will get a more seamless playback of the video/audio... The flipside is that it starts a little later because it has to buffer beforehand, and when it has enough data to play a specific amount of time seamlessly it will start.. Cutting out the buffering might mean frequent hickups during play... The first case might be acceptable for users (buffering) the second one definitely isn't (frequent hickups)...

well an option is just to create your standard webpage (taking into

something like :

web.getSettings().setJavaScriptEnabled(true);
web.getSettings().setJavaScriptCanOpenWindowsAutomatically(false);
web.getSettings().setPluginsEnabled(false);
web.getSettings().setSupportMultipleWindows(false);
web.getSettings().setSupportZoom(false);
web.setVerticalScrollBarEnabled(false);
web.setHorizontalScrollBarEnabled(false);
//Our application's main page will be loaded
web.loadUrl(http://www.yourwebsite.com/mobileversion;);
web.setWebViewClient(new WebViewClient() {

I help run an online wiki, and I'd love to have it so that a mobile
optimised version of the wiki appeared at the top, and the menu button
merely put them on the correct categories (wiki pages like items,
characters, areas, cultures etc).
Unfortunately for me, android is the only thing that's really inspired
me to actually start working on this sort of thing, and I have no
previous java experience, just 10 or so years of html/php/mysql/css.
so my question is, is there a great list of tutorials out there that I
can use to get to this goal? I've looked around the web, but all I've
been able to find is out dated tutorials that seem to create more
errors than they actually help me. Nothing specifically out there for
web that I can find either.
I'm sorry if that's confusing as a request, if it helps, engadget.com
have pretty much exactly what I'm looking to build.

[android-developers] Re: Android Phones
Sure you can look out for a cheaper option, but you specifically asked for other places to buy a testing device outside of the market... So I guess the options would be to buy a second hand device, paying the going second hand price... If that is too much for you then I simply guess thats also the answer : you cannot afford a real testing device... Maybe an option would be, if it's possible in your country, to take on a subscription which also includes a device ? Here in the netherlands you can get a provider's subscription for 18 euro a month which will come with a HTC Tattoo for example... I am afraid that expecting to get a high-end 570$ device for like 100 bucks is up there in my wishlist next to my Ferrari for a 1000 bucks and my uber hexacore pc for 200 bucks... I guess that's what they call the market ;) High-end stuff simply is expensive, for people who cannot afford that there are loads of other options, like getting a cheaper model... There are several android devices who aren't that expensive, like the HTC Tattoo and the Samsung Galaxy (if i'm not mistaken)...

I mean you are saying it was an advanced platform in 2008, but what you want to say that it hasn't evolved since 2004, since J2ME MIDP... A class like MediaPlayer is actually based on that one (which is old and has never been updated nor up par) with the same functionality !

On the other side, as a music app developer I don´t know how you are happy with Android. First, a lot of developers (including me) can´t even figure out how to acquire audio streams from AudioRecord and play them using AudioTrack without problems such audio chopping, sample rate differences, distortion, ... (see how many posts without solutions we have here on this group). We can´t syncronize audio input and ouput, or audio output and video, so it gets hard to develop apps that need to handle those events precisely, such as samplers, music games, music makers based on gestures, etc. We don´t have a low latency audio interface to access (ALSA would be great and it´s already working on Android ... but we can´t access it), so give up virtual instruments and low latency audio apps (small buffers aren´t available too). We don´t have native audio interfaces officially supported by Google and AudioRecord (at least running on the emulator) warns buffer overflows if you just receive audio from it and play using AudioTrack on the same thread, it doesn´t matter which buffer sizes you use. The behavior of the apps running on different devices is unpredictable while on iPhone, since the archtecture and hardware is a lot more closely related on different devices and thought to be compatible, it ´s a lot easier to predict, test and publish apps that you know that will run as great as you intended them to be. On Android this is not something up to the developers to do, but to Google and the device developers that should garantee compatibility with the OS and what runs on top of it. I´m working on Android mostly because of Apple´s restrictions on it´s plataform, on publication, on development, on resources usage...

Two of these really popular apps are BeatMaker and Noise.IO. Beatmaker is a sample driven sequencer MPC style, and Noise.IO is a full featured FM synth. I read something disturbing in the app info yesterday that shows just how much power Apple has over developers. In the past Beatmaker and Noise.IO had formed a way to share data - the ability to export a synth sound out of Noise.IO and import it into Beatmaker. It looks like Apple now forced them to change how this sharing works - in fact so much so that currently the export feature in Noise.IO is GONE! And the lastest reviewers of the app aren't happy about it LOL. And the Beatmaker app indicates that import is gone in the current update. Imagine LOSING functionality in an update! Wouldn't that piss off a customer! Anyway the Beatmaker page mentions something about having to switch over to Apple's copy/paste functionality instead of the way they were using before, and that this was requested by Apple. So that makes me feel much better about Android, I think it sucks when a product that has been out for a long while already, and now Apple comes in and bullies the developers to break their software basically for no good reason except they want some control over how stuff is done. How obnoxious. Also, I dont see how Apple is so groundbreaking. I was looking up specs on the iPhone OS 3.0 yesterday, and it didn't come out until June/July 2009, this is when it finally got copy/paste, MMS, and Push notifications. By the way Push notifications are where an app can get notified to start when it receives some data, even though the app isn't running. Well, Android was well along the way already back in 2008 and it had Widgets and Intents, which do this already. Push notification is just a widget with an intent basically, and it came out much later. I

oki I soved this myself :P Had to place my images and resources under the drawable-mdpi folder... when I created the project for some reason the IDE itself created and placed nearly everything under the drawable-hdpi folder...

That is, on the Eclipse renderer, the one who shows you how it will look like on the device... Thus not the emulator itself...

[android-developers] passing values from Activity to Activity
Hi, I have an app which makes use of several layout-views...Every layout- view also got a class for it, which extend the Activity class... One class for example retrieves some database values whilst offering a search form to the user... Afterwards the user can select one of those values and he gets presented with another screen which gives similar options as the one selected... Anyways, I'd like for the first Activity to be able to send an array with data (Strings for example) to the second one... Right now I show an activity by using : Intent i = new Intent(this, activitysName.class); startActivity(i); I have no idea whilst using this construction how I can initialize the new object with the String array I want to pass to it... So how should this be achieved ? Should I be using something else instead of an Intent-Activity combination ?

Call getStringArrayExtra() on the Intent in the receiving Activity to get it back. I have no Intent in the receiving Activity ? Or is that the Bundle which comes with public void onCreate(Bundle savedInstanceState) ?

[android-developers] Re: passing values from Activity to Activity
aha ! look at that ! thanks a lot for the answer it helped me out :D I have to say that It's all pretty confusing, you got your Java class, your XML layout, your activity, your Intent, your Context, your bundles etc... Inter-object communication isn't very easy (or at least not as transparant as in J2ME), just passign a reference and using its get/ set methods or whatever... Well I did get your book (together with other 4 books!), and after this first hacked demo for our app I will be investing much more time into this complex hierarchy of classes and methologies...

[android-developers] Singleton Service ???
Hi, I'd like to know if it's possible to create a Singelton Service throughout an application ? Let's say I'd like to cerate a Service to play some mp3... I'd like it to be a Singleton, we don't want two mp3 tracks playing through each other (well maybe some would want that, but in my case I'm not making a DJ app) :P Also this Service should be somewhat dynamic as in there should be some interface so that I can stop, pauze and play the mp3 file/ stream... Now I have a couple of questions : - is this feasable ? - should I be using a Service or something else ? - how can an interface be set up inbetween an application and a service so that I can start, stop, pauze stuff ? - can there be something like a Singleton Service ?

[android-developers] Re: Help Needed With Some Layout - UI Problems
well the idea of a tablelayout with just one row is that I want to place two items, one on the left side of the screen and one centered within the screen... so if you have any idea how to achieve this ? Or will a horizontal linearlayout fix that ? I am having a lot of trouble, I love the fact that it's all so customizable but it's somewhat TOO customizable.. I mena if I place a Widget onscreen afterwards I got like 40 fields with options to set... Some are completely criptic, many have a Gravity AND a Layout_Gravity.. what's up with that ? If I place the gravity on horizontal_centered it won't work but if I set the property layout center horizontal to true it will... So I got 3 options, who all seem to do the same but some will work the others won't and God help us there is no good explanation/documentation about it...

[android-developers] Involuntary Scrolling, help !
Hi, I have created a somewhat complex RelativeLayout, in which I also have specified it's width and height as fill_parent.. Now I noticed that even though all my extra widgets within this Layout won't get bigger than the height of my test-device (480px) the whole Layout will scroll somewhat to the bottom... When this happens a black void will apear on top (obviously, the whole thing scrolls downwards), and when scrolling back up it won't close the whole gap and will look like it actually is still scrolled somewhat downwards... Actually, I'd like this Layout to be able NOT TO scroll AT ALL... Any ideas on how this can be achieved ? Also I don't use any scrollviews nor have I set any of the Widgets as Scrollable... Als, whilst I'm typing :P, is there some way to completely negate the moving the phone from portrait to landscape mode ? I am just setting up a first demo of my app and because of time-contraints I only want it to be able to handle portrait mode...

[android-developers] Question regarding Threads and Services
Hi, I'd like to create some sort of Thread which can be accessed by my main program.. Specifically I'd like two classes, both with their own thread, one for parsing XML data and one for doing database operations, without actually interfering with the main UI-thread (slowdowns for example)... I was wondering if those should just extend Runnable, and maybe make them some sort of Singleton, or if these should be implemented as a Service ? Or maybe they shouldnt be implemented at all as an individual Thread ? Are there any known better approaches ? Also I'd like to know how to communicate data (for example requesting or saving some data from the database Service) inbetween my nain app and a Service, and if this is a smart idea in it's whole ? Thanks in advance for any tips, pointers, help or code :D -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Question regarding Threads and Services
Hi Mark, first of all thanks for your answer :D I come from a J2ME background in which I had the same problem, i.e I need to have a always-existent database interface and a always- existent xml-parser which (in J2ME) I placed in a singleton Thread, so that they could be paused when needed and they could get to work when, well, they needed to parse data and/or write/retrieve data :D My knowledge atm is pretty lacking regarding all those things of Android (like activities, tasks, Context or the mentioned asyncTask and intentService) but having a marketing peep as a boss I have a very strict deadline (next monday) to set up a first demo of the app... For me this means I cannot dig too deep into the subjects and most probably I could use the simplest possible implementation... The problem with Threads in the form of a SIngletong(as I undertsood from the selective reading I have done) is that those can be closed anytime by the underlying OS, which in my case would block the whole app :P Also the quesiton remains about inter-class (or in this case interprocess) communication ? How can this be done safely but most importantly as fast as possible in regards to studying theory for it ? Thanks again Mark...

Specifically I'd like two classes, both with their own thread, one for parsing XML data and one for doing database operations, without actually interfering with the main UI-thread (slowdowns for example)... Use AsyncTask for each of these. I was wondering if those should just extend Runnable, and maybe make them some sort of Singleton, or if these should be implemented as a Service ? Use AsyncTask, perhaps mediated by a Service. I'd probably use a Service, only because I like a stable foundation where I can get it, and activities tend to be twitchy (e.g., user presses BACK, and they get destroyed). But, since you're asking this in a very abstract fashion, I have no idea if a Service is necessarily right for your case. Another possibility, instead of AsyncTask, is to use an IntentService. They both allow you to do work in the background without your own thread management. I tend to use IntentService more for totally asynchronous stuff (e.g., app widget updates, alarms with AlarmManager, etc.), where I want the service to go away when there's no outstanding work to do. Or maybe they shouldnt be implemented at all as an individual Thread ? Forking your own threads should only be taken after you have investigated AsyncTask. AsyncTask doesn't handle every scenario where you might use threads. However, since AsyncTask lets you do background work without your own thread-management code, it is definitely worth looking into. At the risk of sounding self-serving, you might want to look into getting a book that covers threads and services in Android.

[android-developers] Sending some data when requesting XML
Hi, I have been using this code to parse some XML data from a specific server : URL url = new URL(http://myserver.com/someXMLScript;); URLConnection conn = url.openConnection(); InputStream is = conn.getInputStream(); Xml.parse(is, Xml.Encoding.ISO_8859_1, new ExampleHandler(myAdapter, this)); Now I was wondering can I add a String or something to this request so that, for example, I might be supplying the device's unique ID to this request for the XML file ? So I don't just want to parse the XML but I also want to send along a String...

[android-developers] Re: Question regarding Threads and Services
owh mostly for being more memory efficient ? :D I have tried with the AsyncTask, which seemed like a great option for me (especially being able to do an updateProgress) but unfortunately my situation is somewhat more complex :( In my situation I have a main class (with the main UI Thread obviously), then I have the piece of code I pasted at the beginning which starts the parsing (which I placed within a AsyncTask) and then obviously I have my ExampleHandler for the actual XML parsing... So i'd like to show on the UI how far the parsing is, especially because atm while debugging my device takes 3 whole minutes to debug around 1800 XML Elements ! The problem obviously relies in the fact that the call to the parsing is in the AsyncTask, NOT the ExampleHandler itself, and it's the ExampleHandler who knows how far it is with parsing... So my question would be : Is there some way for me to keep the Xml.parse() code in a AsyncTask class and actually get the updates from within the Handler ? Also, does a Handler actually spawn it's own Thread, btw my ExampleHandler extends DefaultHandler ? Should I be placing the ExampleHandler (or extending it) within a AsyncTask instead of the call to Xml.parse() ? I am actually somewhat confused atm :( On 9 feb, 17:32, Frank Weiss fewe...@gmail.com wrote: The AsyncTask pattern already provides a thread (from a pool) that you can use anytime you need one.

well maybe out of security reasons ? mostly because of the fact that the used server already reads out POST requests instead of GET... hhmm, I guess that with httpClient I cannot use the uber-simple code I am using at the moment :P for parsing that is :D On 9 feb, 17:45, Frank Weiss fewe...@gmail.com wrote: Why post instead of get?
