Android :: Notify Activities Of Download Completion?
Aug 12, 2010
My application has an IntentService which runs periodically to download data from a remote server. The download task is run inside an AsyncTask which has reference to Application context only. The data downloaded is for entire application and is displayed across four different activities. When the download completes(AsyncTask completes) the service is notified of the same. Now, the service needs to notify appropriate activity to update its view. The service is not aware of which Activity of what application is in foreground.
How do I make that connection? How does the service pass a message to the activity in foreground that new data is available and it should update its views?

Unix shell users might find this useful. It's a bash script that adds intelligent tab-completion for "adb" commands and options: http://github.com/mbrubeck/android-completion
If you've written any other shell completion scripts for the Android SDK, let me know. I'd be happy to add them to this repository.

The only thing I found is to cross compile bash. Is there another way to have tab completion in the Android shell?

I have 2 problems with the MultiAutoCompleteTextView.
First and the main one:
How can i get rid of the comma at the end of the completet word when i use the CommaTokenizer. do i have to implement it on my own?
Second problem:
Is it possible to complete in a way that i don't need to press the down button and then enter. i want to type just enter without the down key first like in office applikations or safari.

For some reason my onPostExecute() is not called after my AsyncTask finishes.
My class decleration:
CODE:.......
Everything works fine, my doInBackground() completes successfully and returns a Boolean but then it just finishes.

How do you stop the Android softkeyboard from displaying completed text in a TextView. It is very important for my application that the spelling is not shown. In 1.6 SDK I made the InputType = VisiblePassword and that seemed to stop it, however this does not appear to work in the 2.1 SDK.

My application is basically a image viewer. It is opened from both camera and as a separate application.
I open the image viewer to view and edit the picture. Each edit operation is implemented using thread. If my application closes due to pressing the home button, the next time I open it with camera. It throws anr.
This doesn't always happen. Only when large edit operations or edit operations on large image files are done.
I get out of memory error, sometimes timeout.
I guess it s because the thread doesn't complete the edit operation when home is clicked. and it s still running on the background. so when i open it s unable to process it.
m I right?
If so what is the way to stop a thread before the completion?

I just got the Galaxy S3 today and I noticed that my word completions and autocorrects aren't working. What I'm talking about is if I type in "tezting" it won't correct to "texting" when I press space. I have to manually select it. Also, the substitutions like "dont" to "don't" aren't working either. I have word completion (to 5 letters), spell correction, and auto-substitution checked.

I cobbled all of this together from various places on the web, but I think the credit for the binaries goes to Paul @ MoDaCo.
Nandroid before going any further!
Files you'll need:
QuickSSHD (Download this from the Market. $1.50). I'm just going to assume if you're still reading, you know what this is for and how to use it. It's braindead simple. I think dropbear can be installed and configured manually, but for the $1.50...meh.
The rest are zipped up here: terminfo.zip, nano, bash, profile**
Unzip bashnano.zip onto your SDCard.
From adb shell:
CODE:.................
I'm not sure if this setup will have any impact on sh scripts being used in the various ROMs, so use this at your own risk.
This will give you full bash over adb, but I haven't figured out where profile goes to add terminal/color et al. for adb.

I've got an update on my Samsung Galaxy S3 today and after that i cannot find my wordlist (personal dictionary) or the possibility to adjust the "word completion point" The whole menu are now only about how to use other social media to "learn" the phone how you're typing.....
Where to find the dictionary and where to adjust the "word completion point" from 2-3-4 or 5 letters?

I had my physical keyboard open and I started to get word prediction at the bottom of the screen again. But I cant figure out how to get it every time the physical keyboard is open. Most of the time I get nothing but this is the second time I have seen this at the bottom. Anyone know what going on with this. There isn't a setting for it for built in keyboard settings page. I wish it would work all the time because it is a nice feature.

I have an activity, it needs to response to a broadcast event.Since an activity can not be a broadcast receiver at the same time,I made a broadcast receiver.My question is: how can I notify the activity from the broadcast receiver?I believe this is a common situation, so is there a design pattern for this?

I have a problem handling messages in a Thread. My run-method looks like this The problem is that the run-method logs "id from message: null" though "message ID" has a value in the Log-statement. Why does the message "lose" it's data when being send to the thread? Has it something to do with the notify?

I have built an application that listen to call state changes, and I want to notify a service when the call_state became IDLE.All the components I have are functional, I just need to notify (not start) a service for this.What's the correct practice, maybe using AIDL? Because, in a PhoneStateListener, I can't bind to a service. Do I have to start an activity for that?

Just watched Google IO's "World Of ListView" presentation [1]. Awesome stuff. I think every Android dev should watch it.
One gotcha for me was to use BaseAdapter.notifyDataSetChanged[2]. I checked code that I have written more than a year ago and found that I did try to use that, but commented it out with '// doesn't work' and I use requery() instead. That is of course much slower.
I now tried to find out why I wrote that it didn't work and hoped that I am meanwhile so much wiser that it would be easier to understand the proper use of the API. So much for ambition: The effect I see is that the list is not updated after I call notifyDataSetChanged(), but works with requery() and I am not so much wiser.
What could be the issue here? I use a ResourceCursorAdapter and only implemented the bindView() Method. This method is called when I call notifyDataSetChanged() on the RCAdapter. However the method is called with a cursor that contains the stale data.
Now there was a second gotcha from the presentation that I couldn't really place. It was said that the data should be committed on the GUI thread too (before calling notifyDataSetChanged()). I couldn't place it then, but I now suspect that this may be the issue here. So the rule would be to do the commit() on the Cursor on the UI thread? I do the updates to the database using a Service. This Service runs in the background, sometimes the app is in the foreground at the same time, but most often not. So I don't see how I should commit something in a UI thread? Is this the issue here? There are two different Cursors and I could only use notifyDataSetChanged when it would be the same cursor, otherwise requery() is correct?
Is that it? Any ideas? Is somebody going to write a book "The Android SDK - The missing manual"?

I need some help using ListActivity. The API provides "onListItemClick" which you can override and is called when user selects an item in the list.
However I want the same type of functionality when an item in the list is selected. So as soon as user highlights something in the list I want my application to do something (like play a preview). I dont want to wait for user to select the button.

I'm trying to clean up some code and now I'm determined to get this seemless ListView updating working...
I want my ListView to be updated when I call notifyDataSetChanged() but nothing happens... I'm also passing the autoRequery flag to true when creating my CursorAdapter.
Cursor c = FavoritesHandler.getCategoryFavorites(getSQLiteInstance(), category); m_favoriteAdapter.changeCursor(c); startManagingCursor(c);
