Android :: Executing 2 Async Tasks

Dec 21, 2009

In the documentation, I read that it is not possible for executing 2 Async Tasks. If execute is called again, it should throw an exception.

The following is given under the heading of "Threading Rules", and i quote:

"The task can be executed only once (an exception will be thrown if a second execution is attempted.)"

I wish to understand the meaning of this statement.

Does this mean, that if i try and execute the same task twice (concurrently) when the first execution of the task was still going on...an exception will be thrown ? Will i need to wait for the completion of the first task, before i spawn a second task ?

A possible use case:

The user wishes to download a set of files. He clicks on the download button by providing the URL. When the first download is still going on, he wishes to download another file and provides another URL. Both these user actions are serviced by a DownloadTask, that extends the AysncTask.

If i wish to change this default behavior, is there a configuration option?

Android :: How To Do Async HTTP Requests?

Feb 23, 2010

Im using a web service, so I want to use an async thread for the HTTP authentication request and another thread later to make additional service requests while my main thread runs.Would like to see a good example of how to do this and how to show busy messages somehow in main app. How does the main app know when the thread finished? And what if my thread encounters exceptions, how do I deal with that?HTTP requests are sent later, use the same cookies setup up by the first auth request, so will the later requests pick up the same cookies and just work?

Android :: Way To Write Async Socket With Phone?

Jul 14, 2009

I am developing a program that needs async socket. I am new to Android and Java. As I can see in the document, to write network program, I got Socket and SocketChannel, but it seems they are all sync socket, it means, I need an extra thread to call blocking read, write... and etc. Here comes the problem, my program is a chat room, the communicate is not linear, I have no idea when the server will send a message to me, if I read in that thread to wait message from server, but the user want to send message to server, the reading function blocked forever, if there is no incoming data, then the pending outgoing message will not be sent. That's why I need async socket. So my question is: How to write async socket under Android environment?

Android :: Does Async Task Queue Or Similar Exist?

Jun 12, 2010

I read somewhere (and have observed) that starting threads is slow. I always assumed that AsyncTask created and reused a single thread because it required being started inside the UI thread.The following (anonymized) code is called from a ListAdapter's getView method to load images asynchronously. It works well until the user moves the list quickly, and then it becomes "janky".final File imageFile = new File(getCacheDir().getPath() + "/img/" + p.image);image.setVisibility(View.GONE);view.findViewById(R.id.imageLoading).setVisibility(View.VISIBLE);
(new AsyncTask<Void, Void, Bitmap>() {
@Override
protected Bitmap doInBackground(Void... params) {
try {Bitmap image;
if (!imageFile.exists() || imageFile.length() == 0) {
image = BitmapFactory.decodeStream(new URL(
"http://example.com/images/"
+ p.image).openStream());
image.compress(Bitmap.CompressFormat.JPEG, 85,
new FileOutputStream(imageFile));
image.recycle();
}image = BitmapFactory.decodeFile(imageFile.getPath(),
bitmapOptions);
return image;
} catch (MalformedURLException ex) {
// TODO Auto-generated catch block
ex.printStackTrace();
return null;
} catch (IOException ex) {
// TODO Auto-generated catch block
ex.printStackTrace();
return null;
@Override
protected void onPostExecute(Bitmap image) {
if (view.getTag() != p) // The view was recycled.
return;
view.findViewById(R.id.imageLoading).setVisibility(
View.GONE);
view.findViewById(R.id.image)
.setVisibility(View.VISIBLE);
((ImageView) view.findViewById(R.id.image))
.setImageBitmap(image);
}}).execute();I'm thinking that a queue-based method would work better, but I'm wondering if there is one or if I should attempt to create my own implementation.

Android :: Async Thread Aborted After Catching (all?) Exceptions

Nov 11, 2009

I have the following code...

CODE:.................

My mClient get method is a simple HttpClient execute with an output buffer to read the input stream, so it's very trivial. Everytime I execute this task UnknownHostException will be triggered which will in turn call onTaskError on my currect Activity, but I still get a RuntimeException, but I don't see why. Maybe it's because it's late and i've done about 12 hours of writing code so it's something simple I just can't see?

Android :: Application Of Image Editor Not Executing

Apr 19, 2010

I am devoloping an application of image editor. I always do it by using the resources in the drawable carpet. Now I changed it to use the resources in the SD card. I don't change the code of the image access but the program always produce an error if I intent to set the value of a pixel. The program works correctly if I try to read the pixel but if I try to modify it fails. I think this is a permissions error but I added the following: <uses-permission android:name="com.android.editorImagenes.permission.WRITE_EXTERNAL_STORAGE"­></ uses-permission> <uses-permission android:name="com.android.editorImagenes.permission.WRITE_OWNER_DATA"></ uses-permission> And everything remains exactly the same. I'm desperate. A thing happens is that if I try to do the scaling or rotating the image using a matrix postrotate, etc, the program works correctly and as of this moment I can use the SetPixel without causing error.

Android :: Activity Executing Code While Screen Is Black

Sep 22, 2010

I've a lot of initialization code in my main activity's onCreate(). When I launch my game, the screen goes black for a long time, then my game appears. I did logged some message at the start and end of onCreate() and found that onCreate() is executing its code while the screen is black. Sometimes the screen goes black for too long and phone shows a popup dialog prompting me to choose between Force close/Wait. Then when onCreate() is completed, my game appears. Choosing 'Wait' then dismiss the dialog.

I tried using progress dialog described in this article:

http://developer.android.com/guide/topics/ui/dialogs.html#ProgressDialog

But it doesn't work. The screen goes black for the same amount of time even after I use the progress dialog.

Android :: WebView Pre - Executing Java Before Loading Page

I would like to a WebView to run some JavaScript before loading the rest of the page. This JavaScript should run in the same context of the page, just as if extra <script> content were added before any other <script> content. This is not possible with add Java script Interface() since I want to set up some instance variables, before the page scripts are run, so that the page scripts can use them.

Android :: ASync Task Progress Dialog Not Showing Until Background Thread Finishes

Apr 24, 2010

I've got an Android activity which grabs an RSS feed from a URL, and uses the SAX parser to stick each item from the XML into an array. This all works fine but, as expected, takes a bit of time, so I want to use AsyncActivity to do it in the background. The line items = parser.getItems() works fine - items being the arraylist containing each item from the XML. The problem I'm facing is that on starting the activity, the ProgressDialog which i create in onPreExecute() isn't displayed until after the doInBackground() method has finished. i.e. I get a black screen, a long pause, then a completely populated list with the items in. Why is this happening? Why isn't the UI drawing, the ProgressDialog showing, the parser getting the items and incrementally adding them to the list, then the ProgressDialog dismissing?

public void onClick(DialogInterface dialog, int which) {
switch (which) {
case 0:
setMode(TRAINING_MODE);
case 1:
setMode(QUIZ_MODE);

setMode(TRAINING_MODE);
break; ............
//continue loading the rest of onCreate();
contineOnCreate(); } })
.create().show();

If this is impossible can anyone give a possible solution?

Android :: Inside Service Class / Executing Method For Toast From Scheduled TimerTask

Apr 30, 2010

I am trying to execute a {public void} method in Service, from scheduled TimerTask which is periodically executing.This TimerTask periodically checks a condition. If it's true, it calls method via {className}.{methodName};However, as Java requires, the method needs to be {pubic static} method, if I want to use {className} with {.dot}.The problem is this method is for notification using Toast(Android pop-up notification) and Status Bar.But for this to work, the method must not have {static} modifier and resides in Service class.So, basically, I want background Service to evaluate condition from scheduled TimerTask, and execute a method in Service class.Can anyone help me what's the right way to use Service, invoking a method when certain condition is satisfied while looping evaluation?
