Android :: Ways To 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.

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.

ADW things
Still in beta at this point
Very different launcher in a lot of ways.
Has left to right scrolling in the app drawer instead of vertical.
Has 2 main dock spaces for icons but if you swipe up on the app drawer instead of pressing it you will see what he calls the dock bar which has space for 6 more dock spots.
Tons of customization options.

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'm releasing my first app soon, and this is the first time I'm doing any of this on my own. Looking into the future of it, there are features I plan to implement within the coming months. But looking at me adding features, I realize I would be altering the original source, so if someone finds a bug, I need to either wait, or completely undo everything to fix it. What are some options for managing my source code and stuff?

AK Notepad does this nice little thing where, on displaying the file list, it "unravels" rapidly down the screen. Are they hacking that incredibly manually, or are there simple OS calls to make lists display in various ways?

I'm looking for ways to back up the database of my app on an Android phone. I know that SQLite databases are just files, so I'd expect to be able to just copy the file to SD-card if one is available.However, I'm unsure as to how I'd prepare my database/activity for backup/restore.
When starting, my main activity reads the entries from one table in the database and displays them in a ListView. As shown in the API's "Notes" sample, I have a cursor that is automatically notified about changes to that table (ListView is automatically updated when I add/remove/update records in the table).When I copy the database file to SD-card, I should not have a problem. But what if the user wants to restore a database file? I can't just copy the file back to the data folder, can I (EDIT: ... while a view displays data from the database and thus maybe holds an open connection)?
What would be "best practice" when implementing backup/restore? One approach I've considered is:Open a special "restore" activity that holds no open database connections
Call finish() for the main activity to remove it and close database connections Copy back the database file Open a new "instance" of the main activity all finish() for the "restore" activity,....Would that be the way to go? Thanks for any advice!

I need 2 ways of showing vertical label in Android:
Horizontal label turned 90 degrees counterclockwise (letters on the side)
Horizontal label with letters one under the other (like a store sign)
Do I need to develop custom widgets for both cases (one case), can I make TextView to render that way, and what would be a good way to do something like that if I need to go completely custom?

I'm a new Android developer and I just released a free, open source tipping calculator app called Tippy Tipper.I created this app to get myself familiar with Android and to hopefully provide a good example app for other new developers to look at.Now that I've overcome the challenges of learning how to program, test and release my Android app, I've come across a new challenge: marketing!What are some good ways to promote my app to the Android community? Can anyone with some experience talk about how they did this successfully with their own app?

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 a free app that has 64% of ratings at 5 starts, but still has 9% of ratings at only 1 start, some of them even said that my app is an "useless garbage", so I think maybe I need to leave a reply to those users to explain something or answer their questions. So are there any ways that we could do such thing?
