[android-developers] Re: singleTask + activity stack not preserved?
Just curious since you and others have asked similar questions in the past. I just wrote a simple App with ActivityA and ActivityB where A is singleTask launchMode. If I go A-b-Home-relaunch I get gack to B. So I cannot replicate the scenario you describe. The code and all files for the app are just a couple of dozen lines so I can post if here if that would be helpful to figure out what you are doing differently than my test.

ActivityA launches ActivityB from a button click. ActivityB is a normal activity with no launchMode set (standard). With ActivityB on top of the activity stack, I hit the home button, then resume the app, I see ActivityA instead of ActivityB when resumed. Shouldn't the history stack be preserved in this case, and B be showing? When I resume, I see A get onNewIntent() called, and I'm not sure why this is happening.

[android-developers] Content Length -1 in HTTP Response / Parial Read
Hi,
1. Implemented an application, that does a webservice call to our
servers. when the response size is around 200 Kb, iam receiving the
content length as -1. It works well in Droid/ADP1/etc (receiving the
original length) but fails in HTC My Touch and HTC DREAM.
2. When i replace, the content length , with 20 , when the
content length is -1. Still, cannot able to read the complete chunk
from the input stream.
This issue can be in other devices too.
The issue could be with the buffer size/allocation ?
Here is that piece of code:
private byte[] doHttpRequest(String url,String req) throws
IOException {
InputStream is = null;
HttpURLConnection c = null;
OutputStream os = null;
String errMsg = null;
try {
c = (HttpURLConnection) new URL(url)
.openConnection();
c.setDoInput(true);
c.setDoOutput(true);
c.setConnectTimeout(15000);
c.setReadTimeout(4);
c.setRequestMethod(POST);
c.setRequestProperty(Content-Language, en-US);
os=c.getOutputStream();
os.write((mobile_request= +
StringStuff
.URLEncodeStr(req).getBytes());
rc = c.getResponseCode();
if (rc != HttpURLConnection.HTTP_OK) {
throw new IllegalResponseCodeException(HTTP
response code:
+ rc);
}
is = c.getInputStream();
int len = (int) c.getContentLength();
// Length=-1 , incase of HTC DREAM/HTC Touch
if (len 0) {
int actual = 0;
int bytesread = 0;
byte[] data = new byte[len];
while ((bytesread != len) (actual != -1)) {
actual = is.read(data, bytesread, len -
bytesread);
bytesread += actual;
}
return data;

[android-developers] OpenGL Texture Scaling Problem

[android-developers] TranslateAnimation z-order problem
I've come across a curious problem: I have a simple horizontal LinearLayout: Button A - ViewGroup (vertical LinearLayout containing TextViews) - Button B It's important to note that the views are defined in the XML in the above order i.e. Button A, ViewGroup, Button B. I have a simple TranslateAnimation: 1. Press Button A and the ViewGroup gets animated off the screen to the right, past Button B. 2. Press Button B and the ViewGroup gets animated off the screen to the left, past Button A. In the case of #1, the animation happens with the ViewGroup being animated *behind* Button B. In the case of #2, the animation happens with the ViewGroup being animated *above* Button A. This happens specifically because Button A was defined before the ViewGroup in the layout XML. I've tried changing the Z adjustment for the animation but this has no effect. What I want is to have both animations happen behind the buttons (i.e #2 same as #1). I don't want to have to re-arrange my layout to have to define the ViewGroup first and I've tried bringing Button A to the front but that messes with the overall layout when the ViewGroup is off the screen, with Button A ending up next to Button B on the right. Any ideas? It seems like the Z adjustment isn't doing what it should. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Can't show ProgressDialog during listview update
What am I doing wrong here? I have a listview of items (songs on the
sd card). The user has an option to load all the songs on the sd card
to into a current playlist -- those songs are what is displayed in the
listview. Because this can take few seconds to load if they have a lot
of songs on the card, I want to display a progress dialog to just tell
the user One moment... until the list refresh is done.
I launch a thread to do this. I've done this successfully on another
app I have (which just updates a database in the background but
doesn't update any display), but this one fails with this error
message, Can't create handler inside thread that has not called
Looper.prepare(). I chopped down the activity and pasted it below.
What am I doing wrong here? I have just a vague idea of what might be
happening.
By the way, everything works when I take out the threaded stuff, it
just looks like the app freezes for a couple seconds.

[android-developers] How to implement UI for re-ordering a list?
I have an Android app where users can add items to a ListView, and I'd like them to be able to re-order the items in the list however they want (as opposed to just offering them different sort orders). It's easy enough to add a position setting for the items (they come from the DB) but what kind of UI elements are available for the user to indicate the desired ordering? Is there a pattern anyone has seen implemented for this? I have not seen anything on Android that does anything like this, except the home screen which is similar but looks a little bit beyond my expertise at this point. The best I can think of is to use a long click and context menu to move up or move down.

Re: [android-developers] Can't show ProgressDialog during listview update
Use AsyncTask instead od Java threads. I'm not kidding, it's that simple.

I launch a thread to do this. I've done this successfully on another

By the way, everything works when I take out the threaded stuff, it

[android-developers] Re: Need Samsung Moment user to help troubleshoot problems
Ernest, Your response is helpful. I am not using android.opengl.GLSurfaceView, but I did try to get my EGL config chooser routine to look like what is provided therein. Are you saying that if I did use GLSurfaceView from Android I would not have the issue? If so, is there any specific parameters I would need to pass in for initialization of the GLSurfaceView or the Renderer in order for EGL config to be chosen properly? I thank you and look forward to any findings if you take a look at ongPay! On Feb 18, 1:00 am, ernestw ernest...@gmail.com wrote: Dan, thanks for the reply but I was able to get my hands on a Samsung Moment, confirm the issue, and provide a fix. This particular problem was caused by a call to glDrawArrays. In FRG, I use glDrawArrays with GL_LINES to draw parts of the in-game UI. One of the calls to glDrawArrays passed an odd number for the 3rd parameter of glDrawArrays. Effectively I was asking to draw a number of lines plus one point. Apparently this doesn't cause issues on a HTC Dream, Magic, Hero, Nexus One, or Moto Droid. On the Samsung Moment, the phone display freezes probably due to the CPU being pegged (I confirmed that when freeze occurs, logcat still logs CPU pegged? messages). Definitely a bad error on my part. Dan, if you wish to see the bug in action, search Android Market for FRG Lite. Watch out you'll have to pull the phone battery once it freezes. Shaun, a while ago I ran into one other crash bug on the Samsung Moment which was caused by my EGLConfig selection routine. FRG tests available EGLConfigs by creating a small GLSurfaceView in the splash screen. In it, I run a custom EGLConfig chooser and check if the resulting config is hardware accelerated or not. If software rendering is used, I display a warning for the user and disable sound and music in hopes that the game will still run adequately. My original EGLConfig selection resulted in EGL_SLOW_CONFIGs (i.e. software renderer) being chosen for the Moment. After the splash screen is finished, FRG would crash with a segfault. My guess is the Moment fails horribly in cleaning up a software-rendered surface. To fix this issue I had to make sure my EGLConfig routine didn't ignore unknown EGL_CONFIG_CAVEAT values, i.e., for hardware acceleration on the Samsung Moment, you must choose the EGLConfig that has EGL_CONFIG_CAVEAT that is not EGL_NONE, EGL_SLOW_CONFIG, nor EGL_NON_CONFORMANT_CONFIG. Not sure if you'd have this problem as your game would segfault without fail upon cleaning up any OpenGL surface. You also have to be using your own EGLConfig chooser for the bug to possibly happen. I have limited time with the Samsung Moment tomorrow but after I test out my fixes for awhile, I'll take a look at ongPay! and see how it behaves.

No. You have to do this all yourself :( 1. Query from the mediastore all the info for your original image, including its file-path (DATA column). 2. Query from the thumbnail mediastore the info of all the thumbnails (can have more than one) for the given image. 3. Copy your image-file to another location. Remember this location for the new DATA column of your new image. 4. Insert into the mediastore all the data obtained from point (1.) but set your DATA to the new file-path of your new image (from point 3.). 5. Insert into the thumbnail mediastore the thumbnails of this new image. Use the data from point (2.), but update the IMAGE_ID with the new image-id from point (4.) and make also copies of each thumbnail file (DATA column).

[android-developers] Re: TranslateAnimation z-order problem
Ok, so it's not me doing something stupid. :) Any thoughts as to the best solution? I wrote a simple test whereby I created a RelativeLayout rather than a LinearLayout and defined the ViewGroup first and the buttons after, relative to the ViewGroup, which seemed to work ok in the test. So did calling buttonA.bringToFront() before starting the animation (although it screwed up the layout after the animation was complete by putting the Button A on the far right next to Button B). Neither seem a very elegant solution to what must be quite a common problem (I really don't want to have to re-define my whole layout again as that has implications for the whole app).

I have a simple TranslateAnimation: 1. Press Button A and the ViewGroup gets animated off the screen to the right, past Button B. 2. Press Button B and the ViewGroup gets animated off the screen to the left, past Button A. In the case of #1, the animation happens with the ViewGroup being animated *behind* Button B. In the case of #2, the animation happens with the ViewGroup being animated *above* Button A. This happens specifically because Button A was defined before the ViewGroup in the layout XML. I've tried changing the Z adjustment for the animation but this has no effect. What I want is to have both animations happen behind the buttons (i.e #2 same as #1). I don't want to have to re-arrange my layout to have to define the ViewGroup first and I've tried bringing Button A to the front but that messes with the overall layout when the ViewGroup is off the screen, with Button A ending up next to Button B on the right.

This is what I do and it works well enough for small lists. I would like to do drag-n-drop at some point but it's probably more trouble than it's worth at this point for me so I'll look into that later. Another idea is to have a reorder mode in your app where you let the user click the item they want to move and then do a second click on the item that's at the point they want to move it to, repeating as necessary to move all items. - TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking -- You received this message because you are subscribed to the Google Groups Android Developers group.

Hi,
I have an activity, ActivityA, and its launchMode is set to
singleTask.
I start the application from the app tray. ActivityA launches
ActivityB from a button click. ActivityB is a normal activity with no
launchMode set (standard).
With ActivityB on top of the activity stack, I hit the home button,
then resume the app, I see ActivityA instead of ActivityB when
resumed.
Shouldn't the history stack be preserved in this case, and B be
showing? When I resume, I see A get onNewIntent() called, and I'm not
sure why this is happening. I thought the stack would be preserved.

[android-developers] Re: Can't show ProgressDialog during listview update
I wasn't able to get the AsyncTask to work (although I have used it
successfully in another app). What I did was use the Looper.prepare();
in my run() method:
public void run(){
Looper.prepare();
loadsongs(CURRENT_PLAYLIST);
mHandler = new Handler() {
@Override
public void handleMessage(Message msg){
// refresh the listing of playlists
}
};
Looper.loop();
}
It doesn't crash, but it doesn't show the refresh of the listview
either -- but I think the listview is being refreshed. I have to leave
the activity and return to it to see the update.

Hi,
I have an activity, ActivityA, and its launchMode is set to
singleTask.
I start the application from the app tray. ActivityA launches
ActivityB from a button click. ActivityB is a normal activity with no
launchMode set (standard).
With ActivityB on top of the activity stack, I hit the home button,
then resume the app, I see ActivityA instead of ActivityB when
resumed.
Shouldn't the history stack be preserved in this case, and B be
showing? When I resume, I see A get onNewIntent() called, and I'm not
sure why this is happening. I thought the stack would be preserved.
Thanks

[android-developers] Re: Can't show ProgressDialog during listview update
Using a custom ArrayAdapter doesn't seem to me to relate to your question, unless your problem is that it's broken. For example, if yours doesn't notify the registered DataSetObservers that the data has changed. As for async tasks -- what you're describing IS a one-shot task, in any sense that applies here. sure, you'll have more than one shot. But in between those shots, with an ASyncTask, that thread and all the memory required for its stack, will be available for use by OTHER AsyncTasks, including ones possibly launched by the SDK. You do have to create a new AsyncTask each time -- but that's a small price to pay for significantly smaller memory usage. So it's going to be more efficient than creating your own thread. Use your own thread if you have something that has continuously evolving state -- say some recursive process. Even then, you can generally modify it to work with an ASync task. I've read, on this list, I think, that early versions of ASyncTask limit the pool of threads it uses to one. If that's the case, and you run very long tasks, they may prevent other tasks from running. I wouldn't worry about that unless you run into it as a problem; then would be a time to either move your task into its own thread, or to split your task up so it operates as a series of smaller pieces. And it's my understanding that the pool is no longer limited to one thread, so this is a limitation that will fade. Still, if you are usually consuming one of those ASyncTask threads, you're really not getting any benefit from using an ASyncTask other than a convenient interface to moving that final action back to the UI thread. But it's not hard to do that yourself, either. If you DO run it on your own thread, you can post a message back to the main thread, using a Handler aimed at the main thread's Looper, which you can get via getMainLooper() on any Activity or Application or Service, or the static method Looper.getMainLooper(). If you just call Handler(), it picks up the Looper for the current thread -- I believe that's why AsyncTask states in its threading rules: The task instance must be created on the UI thread.. Basically, you'll be doing what AsyncTask does - but you'll have the flexibility to direct it t the UI thread even if you create it elsewhere. It seems like a character flaw that ASyncTask's default constructor isn't hardwired to send things to the UI thread -- it would prevent a lot of preventable bugs. Just put any code you'd have put in the onPostExecute(Result) method into the runnable you post to your handler. By default, when you flip the orientation, indeed, your activity is destroyed and recreated. But you can specify in the manifest what configuration change events you're prepared to handle yourself, and handle them in onCofigurationChanged(Configuration). If all that's needed is a layout change, you may not need to do anything at all in this method other than call super.onConfugrationChanged(newConfig) -- which, of course, means you don't really need to define the method at all. I recommend doing so, however, to flag that you're actually doing this, and that here's where any configuration change happens. If you have elements of your UI that scroll, you may need to reset the scroll position here. I've seen a number of apps that appear not to do this, and it's annoying. While you can tell that a Thread has ended by checking its state, that's not how you SHOULD be doing things. In Android, use a Handler and post whatever action you want to perform when the thread is ended. At a lower Java level, use the wait/notify protocol to synchronize. There's a clear and reliable usage pattern you can use, but it's a bit complicated to describe, and doing it wrong results in subtle bugs. You may want to consider using a try block, and posting your final action from the finally clause. Declare a variable 'ok' at the start of your function, and set it to true when you reach the end of your code. Choose what code to run in the success and error/failure case based on the flag. This is a good way to communicate errors back to the main thread. I hope all that makes sense... On Feb 18, 4:03 pm, Ken H hunt1...@gmail.com wrote: But what if you're using a custom ArrayAdapter?

[android-developers] Re: Need Samsung Moment user to help troubleshoot problems
I just read you other post and it covers pretty much the same subject matter: http://groups.google.com/group/android-developers/browse_thread/thread/26f577bca4cee64d# I will try to step through to determine what EGL config is choosen. I find is strange in my case because I have one user who comments that ...all I see are floating words that say 'Low Ding' then the screen goes black. Since the words Low Ding are displayed using the same code as all other image-backed sprites, it seems the EGL config was chosen correctly and perhaps another error is occurring, maybe when .. oh yeah, maybe it is the sounds... I say sounds because the Low Ding is displayed just before starting loading sounds. Well, now that just night be it. Although, I would also expect the Yakoin logo to be displayed along with Low Ding because the logo is loaded and added to the scene just before Low Ding.

I am not using android.opengl.GLSurfaceView, but I did try to get my EGL config chooser routine to look like what is provided therein. Are you saying that if I did use GLSurfaceView from Android I would not have the issue? If so, is there any specific parameters I would need to pass in for initialization of the GLSurfaceView or the Renderer in order for EGL config to be chosen properly? I thank you and look forward to any findings if you take a look at ongPay! On Feb 18, 1:00 am, ernestw ernest...@gmail.com wrote: Dan, thanks for the reply but I was able to get my hands on a Samsung Moment, confirm the issue, and provide a fix. This particular problem was caused by a call to glDrawArrays. In FRG, I use glDrawArrays with GL_LINES to draw parts of the in-game UI. One of the calls to glDrawArrays passed an odd number for the 3rd parameter of glDrawArrays. Effectively I was asking to draw a number of lines plus one point. Apparently this doesn't cause issues on a HTC Dream, Magic, Hero, Nexus One, or Moto Droid. On the Samsung Moment, the phone display freezes probably due to the CPU being pegged (I confirmed that when freeze occurs, logcat still logs CPU pegged? messages). Definitely a bad error on my part. Dan, if you wish to see the bug in action, search Android Market for FRG Lite. Watch out you'll have to pull the phone battery once it freezes. Shaun, a while ago I ran into one other crash bug on the Samsung Moment which was caused by my EGLConfig selection routine. FRG tests available EGLConfigs by creating a small GLSurfaceView in the splash screen. In it, I run a custom EGLConfig chooser and check if the resulting config is hardware accelerated or not. If software rendering is used, I display a warning for the user and disable sound and music in hopes that the game will still run adequately. My original EGLConfig selection resulted in EGL_SLOW_CONFIGs (i.e. software renderer) being chosen for the Moment. After the splash screen is finished, FRG would crash with a segfault. My guess is the Moment fails horribly in cleaning up a software-rendered surface. To fix this issue I had to make sure my EGLConfig routine didn't ignore unknown EGL_CONFIG_CAVEAT values, i.e., for hardware acceleration on the Samsung Moment, you must choose the EGLConfig that has EGL_CONFIG_CAVEAT that is not EGL_NONE, EGL_SLOW_CONFIG, nor EGL_NON_CONFORMANT_CONFIG. Not sure if you'd have this problem as your game would segfault without fail upon cleaning up any OpenGL surface. You also have to be using your own EGLConfig chooser for the bug to possibly happen. I have limited time with the Samsung Moment tomorrow but after I test out my fixes for awhile, I'll take a look at ongPay! and see how it behaves.

Re: [android-developers] Re: Intent.ACTION_SYNC no docs or resolveInfo
There is really no such thing as a global data sync. You can write a SyncAdapter to take care of syncing with a particular content provider, and decide when to sync. You can register a ContentObserver to see when the data inside of a content provider changes. A global concept of sync isn't really there.

Ken On Feb 18, 5:24 pm, Bob Kerns r...@acm.org wrote: Using a custom ArrayAdapter doesn't seem to me to relate to your question, unless your problem is that it's broken. For example, if yours doesn't notify the registered DataSetObservers that the data has changed. As for async tasks -- what you're describing IS a one-shot task, in any sense that applies here. sure, you'll have more than one shot. But in between those shots, with an ASyncTask, that thread and all the memory required for its stack, will be available for use by OTHER AsyncTasks, including ones possibly launched by the SDK. You do have to create a new AsyncTask each time -- but that's a small price to pay for significantly smaller memory usage. So it's going to be more efficient than creating your own thread. Use your own thread if you have something that has continuously evolving state -- say some recursive process. Even then, you can generally modify it to work with an ASync task. I've read, on this list, I think, that early versions of ASyncTask limit the pool of threads it uses to one. If that's the case, and you run very long tasks, they may prevent other tasks from running. I wouldn't worry about that unless you run into it as a problem; then would be a time to either move your task into its own thread, or to split your task up so it operates as a series of smaller pieces. And it's my understanding that the pool is no longer limited to one thread, so this is a limitation that will fade. Still, if you are usually consuming one of those ASyncTask threads, you're really not getting any benefit from using an ASyncTask other than a convenient interface to moving that final action back to the UI thread. But it's not hard to do that yourself, either. If you DO run it on your own thread, you can post a message back to the main thread, using a Handler aimed at the main thread's Looper, which you can get via getMainLooper() on any Activity or Application or Service, or the static method Looper.getMainLooper(). If you just call Handler(), it picks up the Looper for the current thread -- I believe that's why AsyncTask states in its threading rules: The task instance must be created on the UI thread.. Basically, you'll be doing what AsyncTask does - but you'll have the flexibility to direct it t the UI thread even if you create it elsewhere. It seems like a character flaw that ASyncTask's default constructor isn't hardwired to send things to the UI thread -- it would prevent a lot of preventable bugs. Just put any code you'd have put in the onPostExecute(Result) method into the runnable you post to your handler. By default, when you flip the orientation, indeed, your activity is destroyed and recreated. But you can specify in the manifest what configuration change events you're prepared to handle yourself, and handle them in onCofigurationChanged(Configuration). If all that's needed is a layout change, you may not need to do anything at all in this method other than call super.onConfugrationChanged(newConfig) -- which, of course, means you don't really need to define the method at all. I recommend doing so, however, to flag that you're actually doing this, and that here's where any configuration change happens. If you have elements of your UI that scroll, you may need to reset the scroll position here. I've seen a number of apps that appear not to do this, and it's annoying. While you can tell that a Thread has ended by checking its state, that's not how you SHOULD be doing things. In Android, use a Handler and post whatever action you want to perform when the thread is ended. At a lower Java level, use the wait/notify protocol to synchronize. There's a clear and reliable usage pattern you can use, but it's a bit complicated to describe, and doing it wrong results in subtle bugs. You may want to consider using a try block, and posting your final action from the finally clause. Declare a variable 'ok' at the start of your function, and set it to true when you reach the end of your code. Choose what code to run in the success and error/failure case based on the flag.

[android-developers] Cannot get textAppearance to inherit/cascade from theme
I have a simple style like this: style parent=android:Theme.Light.NoTitleBar name=MyTheme item name=android:colorBackground#FF/item item name=android:textAppearance@style/PrimaryText/ item /style And a simple style like this: style parent=@android:style/TextAppearance name=PrimaryText item name=android:textColor#FF/item item name=android:textSize14sp/item /style Now, I would expect (from reading everything that is documented) that if I set the theme for my application like so: application android:icon=@drawable/app_icon android:name=.MyApp android:theme=@style/MyTheme then anything in my app that has a textAppearance attribute (like a TextView) would inherit the attributes from MyTheme (and thus the attributes from PrimaryText). But they don't. I tried setting the theme on the specific activity (in the manifest) and that did not work. I set the style attribute on the containing layout like this: LinearLayout android:id=@+id/myLayout android:orientation=vertical android:layout_width=fill_parent android:layout_height=fill_parent android:layout_margin=5sp style=@style/MyTheme android:background=@drawable/round_border and that did nothing (which I believe is expected since this cascading inheritance should only work when applied as a 'theme'). Am I missing something obvious here? Right now I have to set the textAppearance (or style) attribute on every single TextView to get the style. The pain is great. Does anyone have a suggestion on a way to get this to work? While working this I also hit another oddity that may or may not be related. If I take the specific attributes (like textColor and textSize) and put them in MyTheme then they do correctly cascade and apply to all my text. The problem is that they then cannot be overridden by a style. If I set textAppearance on a TextView it appears to be ignored. However, if I explicitly set textColor or textSize then it will be honored and override the theme setting for that TextView. In general it feels like there is some missing wiring or a bit of inconsistency in the application of themes and styling attributes. -- You received this message because you are subscribed to the Google Groups Android Developers group.

i entered some data in portrait mode.
but when i rotate my mobile from portrait to landscape the control
goes to onConfigurationChanged() method.
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
setContentView(R.layout.screen1_landscape);
}
in the above method im displaying one more new screen..
here is the problem that the data entered in portrait mode is not
retrieving in landscape mode..
Please let me know where am going wrong???

[android-developers] Re: Intent.ACTION_SYNC no docs or resolveInfo
Ok Thanks Dianne, What interest me is detecting when new GMail is being received. Wich is the uri of the Gmail content provider? content://gmail-ls ??? is there any documentation somewhere about how the information is being stored in this Content-Provider. On Feb 19, 4:03 am, Dianne Hackborn hack...@android.com wrote: There is really no such thing as a global data sync. You can write a SyncAdapter to take care of syncing with a particular content provider, and decide when to sync. You can register a ContentObserver to see when the data inside of a content provider changes. A global concept of sync isn't really there.

It would be just great to be able to Register a BroadcastReceiver and handle that action, in my case instead of fire a data synchronization i would like to detect when it happens. is it possible?

This action probably should never have been made public, and I don't think it does anything at this point.

I have an app that sends a new entry to Google Calendar in the cloud; I would like to be able to force a sync with Google after adding the entry so that the entry shows up in the user's calendar on the device shortly after being added. Is there anyone who has experience using ACTION_SYNC to let us know what sort of other information e.g. category or data that needs to be passed to the resolver in the intent to let the phone know to sync with Google? Does anyone know if the AccountManager is a way to get this done?

[android-developers] Re: Can't show ProgressDialog during listview update
Just tried the asynctask again, and it works. Basically I put the time consuming part in doInBackground(), and then launched a progressDialog in onProgressUpdate() to let users know nothing froze, and finally dismissed the progrssDialog in onPostExecute(). Also added the final refresh of the listview there. Thanks again guys. Ken On Feb 18, 10:10 pm, Ken H hunt1...@gmail.com wrote: Wow, dude...thanks! That was a thorough answer. Usually get a vague, one sentence response that leaves me more confused than before. I don't know why I said that thing about the custom adapter...I think because I don't truly understand what it's doing and this activity revolves around it. Well, I need to digest all this and try it out. Thanks again. Ken On Feb 18, 5:24 pm, Bob Kerns r...@acm.org wrote: Using a custom ArrayAdapter doesn't seem to me to relate to your question, unless your problem is that it's broken. For example, if yours doesn't notify the registered DataSetObservers that the data has changed. As for async tasks -- what you're describing IS a one-shot task, in any sense that applies here. sure, you'll have more than one shot. But in between those shots, with an ASyncTask, that thread and all the memory required for its stack, will be available for use by OTHER AsyncTasks, including ones possibly launched by the SDK. You do have to create a new AsyncTask each time -- but that's a small price to pay for significantly smaller memory usage. So it's going to be more efficient than creating your own thread. Use your own thread if you have something that has continuously evolving state -- say some recursive process. Even then, you can generally modify it to work with an ASync task. I've read, on this list, I think, that early versions of ASyncTask limit the pool of threads it uses to one. If that's the case, and you run very long tasks, they may prevent other tasks from running. I wouldn't worry about that unless you run into it as a problem; then would be a time to either move your task into its own thread, or to split your task up so it operates as a series of smaller pieces. And it's my understanding that the pool is no longer limited to one thread, so this is a limitation that will fade. Still, if you are usually consuming one of those ASyncTask threads, you're really not getting any benefit from using an ASyncTask other than a convenient interface to moving that final action back to the UI thread. But it's not hard to do that yourself, either. If you DO run it on your own thread, you can post a message back to the main thread, using a Handler aimed at the main thread's Looper, which you can get via getMainLooper() on any Activity or Application or Service, or the static method Looper.getMainLooper(). If you just call Handler(), it picks up the Looper for the current thread -- I believe that's why AsyncTask states in its threading rules: The task instance must be created on the UI thread.. Basically, you'll be doing what AsyncTask does - but you'll have the flexibility to direct it t the UI thread even if you create it elsewhere. It seems like a character flaw that ASyncTask's default constructor isn't hardwired to send things to the UI thread -- it would prevent a lot of preventable bugs. Just put any code you'd have put in the onPostExecute(Result) method into the runnable you post to your handler. By default, when you flip the orientation, indeed, your activity is destroyed and recreated. But you can specify in the manifest what configuration change events you're prepared to handle yourself, and handle them in onCofigurationChanged(Configuration). If all that's needed is a layout change, you may not need to do anything at all in this method other than call super.onConfugrationChanged(newConfig) -- which, of course, means you don't really need to define the method at all. I recommend doing so, however, to flag that you're actually doing this, and that here's where any configuration change happens. If you have elements of your UI that scroll, you may need to reset the scroll position here. I've seen a number of apps that appear not to do this, and it's annoying. While you can tell that a Thread has ended by checking its state, that's not how you SHOULD be doing things. In Android, use a Handler and post whatever action you want to perform when the thread is ended. At a lower Java level, use the wait/notify protocol to synchronize. There's a clear and reliable usage pattern you can use, but it's a bit complicated to describe, and doing it wrong results in subtle bugs. You may want to consider using a try block, and posting your final action from the finally clause. Declare a variable 'ok' at the start of your function, and set it to true when you reach the end of your code. Choose what code to run in the success and error/failure case based on the flag. This
