Android :: Application Widget - How To Manage Updates?
Nov 8, 2009
In the process of creating an AppWidget which displays data from a remote host, I am looking for documentation about how to manage updates. Are there articles somewhere about how and when querrying remote data is the most appropriate? I am wondering if we have to explicitly code the remote queries in a separate thread, or even do it in a separate service, to avoid freezes of the home screen (this happens a lot on my htc magic).

Everyday I see this forum, theres always an update from some dev, almost everyday. How do you guys deal with re syncing some fb contacts, organizing home screens, etc., over and over and over and over again? Plus, u lose all ur sms, call log, app settings, etc.

I want to use the same eclipse project to maintain only one source code (or two projects that refer to a generic project). My problem is that the names of the package have to be different on the market (eg: my.android.app.lite and my.android.app.pro). If the package names are differents, the generated java ressource files are differents (eg: my.android.app.lite.R.java and my.android.app.pro.R.java). So, the source files must point to differents R files according to the version (pro or lite) and I have to change all the import...

I'm a college student, and there's daily specials at bars, salsa dance nights, special meetings, lectures, etc. And all these things happen around me. I don't want to just put them into my calendar and have them flooding it, but I would like some app to hold such things. Anyone know what I can use that isn't my default so I can retain my personal schedule and, if I want to do extra, can see this app's contents?

Is there an app (or even a setting on the Desire itself) that can keep a track of the outgoing calls duration and total on my phone? I've recently dropped from 600 to 300 minutes and want to make sure I don't go over my allocation in the same way the "3G" app tracks my Internet usage!

Is there a way to manage the audio levels through an app? Or is it more dependent on the phone's built in capabilities? Right now at work I listen to a skype audio call from my house (for security) at a very low volume and then at a higher level I listen to music or podcasts, both sources going at the same time. When my dog goes nuts, the door is knocked on, or (in theory) if someone busted down my door, I notice the change in volume and sound, turn off my local media, and focus on what I'm hearing until the drama passes.
I ask because I would like to continue this setup when not at work, like say while running, where I again have earphones in and am normally listening to audio content. I would like to be able to have two pieces of audio: music combined with a skype stream or normal phone call, going at the same time like at work. So is there a way to have two sources going at the same time, with the volume of each independently adjustable? Is this an app thing or a phone thing? Phone will be Sprint Hero.

I have some questions about how the ContentProvider works behind the scenes.
1. The ContentProvider class is registered in the kernel when the application is installed and then what? Or how do the other applications exactly manage to access the application data?
2. When is actually onCreate called? The documentation is pretty vague...
3. What happens if two applications register the same provider class? (I have more applications that must communicate between eachother. The content provider must be registered, of course, along with the first application installed on the system. The problem here is that I don't know which one will be, so I want to deliver the ContentProvider with all the applications)

I'm trying to write a clock widget that displays Epoch time and I need it to update every second.
Currently I'm doing this using a Service that uses a Handler:
CODE:..................
The problem I'm having is that over time, my home screen appears to get noticeably laggy. I'm fairly new to Android so I'm not sure if what I'm doing is the correct approach or if there's a better way to achieve this (maybe with AsyncTask?). Is there a way to update a widget frequently without suffering from UI lag? If I need to post more code, please let me know. My widget simply starts and stops this service, and my appwidget-provder has android:updatePeriodMillis="0".

What is the best approach to managing a small SQLite database private to the application? Open (getWritableDatabase)in OnStart and close in OnStop in each Activity?Open in OnCreate and keep open til the user quits the app (where would you put close?) Open, do work and close as soon as possible each time it is needed?

any application that manages your bluetooth connections?
Here's what I'm talking about, I have bluetooth headphones, several speakers and my car that all are connected to my phone and I'm having several small issues.
- As soon as I turn on bluetooth it tries to automatically tries to connect to these certain speakers, I don't want that and don't know how to stop it.
- If I'm in my car, my phone connected to my car for calls and I'm listening to music through the headphone jack but it will automatically connect to a set of bluetooth speakers in my home when get home and pull into the driveway. So music will play through those speakers instead of my headphone jack. I obviously don't want that either.
-Titanium Backup never restores my bluetooth connection either so if there is an application that can save those too that would be useful.

After upgrade to 2.1 when i am going to "Manage Applications" I am seeing only those apps that I have installed unlike before (1.6) where I could see all the installed apps like google apps, default games etc. Where can I find these apps (in case I want to clear cache or something like this)?

I started using Pure Calendar today and love it.here is a "Select Update Frequency" setting that can change from 6 hours to "When Calendar is Modified."I left mine on 6 hours to begin with, but I have noticed that when I modify my Exchange or my Google Calendar (on my phone OR on my computer), the Pure Calendar widget updates almost instantly.Anybody know why? Is it a bug in the Widget? Or is it supposed to update the Widget instantly despite being set to 6 hours?

I am curious about the procedure for updating an app that was acquired off the market. Do you simply install over your existing app? And if so, what happens to your existing data?Is there a way to tie your installed apps to the market, so it can automatically check for updates? Any information is appreciated.

Hi,
I'm planning to use my website to provide updates for my android application whenever the user decides to perform an update( in case there is one available) . I'm thinking to use http requests for the communication between the user and the server, so whenever there is a new update the server sents back to the user the link to download the apk of the update through the android browser. So far I think it should work !?!. But once I have the apk of the new update on the card ,and the installed old version of the application how do I actually perform the update ?

I just came from a Droid Eris, and the clock/weather widget was spot on as far as changing weather and showing the correct location based on my location in the network. My Fascinate came with the Weatherbug one, but only updates if you refresh. Has anyone found one for the Fascinate that updates correctly?

I am having a problem with the Friend Stream widget. It seems that one of my FB friends does not appear on Friend Stream. I do not see any of her updates. I can only see her FB updates when I use the FB app. I cannot see her in my list of FB friends in Friend Stream either. It seems to not be updating properly on the people widget either. Tried to resync. I even tried deleting my FB account in Friend Stream and adding it back in. This only happened with this one friend. I use to be able to see her updates, but she seemed to have disappeared from Friend Stream a couple of days ago.

I had thought that appbrain is more or less of a mirror of market. How come sometimes I got into appbrain and sync and it shows me no updates, but they I go into the market and it does show updates for some apps?

I'm having a problem when trying to stop location updates when the app goes into the background. In my onCreate() method I start request updates like this:
CODE:........
However the GPS icon remains in the status bar and the only way to get rid of it is to manually kill the application.

I have data that is to be refreshed from the Internet. Let's call it Model.
What I want to do: Basically it sounds like an MVC model, where the Model is also kept persistent in local (private) storage. The Model and its associated methods are application-wise. There are several Activity's that display and manipulate different aspects of it:
User
navigates across different Activity's
that display Model
from different perspectives. Currently I have a ListActivity for all elements, and an Activity for one element's details
Sometimes Model needs refreshing.
Surely this is done on a different thread. Refreshing can be triggered from several Activity's.
There are several (time consuming) common
tasks that can be triggered from different Activity's
My application loads and saves Model
to private storage when it starts
and stops
My problem: I'm not sure where to put Model and the related tasks in. Also, I don't know what mechanism to use to notify Activity's. Currently I come up with 2 approaches:
Use Service and send broadcasts. Saving to disk is performed in Service#onDestroyed(), so I want to minimize that by binding it to Activity's. At this point, I'm also not sure how to deliver the updated information: whether to provide a getter in Binder, or include that in the broadcast message.
Customize the Application object so that refreshing methods and getters are available globally. I then perform update from Activity's using AsyncTask. If there are other Activity's that are behind the current Activity, they will update in onResume() when the user navigates back.
Reasons I'm not using a class with static methods:
I need to save and store Model to disk. Some of the methods need a Context for displaying toasts, notifications, caching, etc.
Also, I don't put these functionalities in an Activity because there are several activities that manipulate the same piece of persistent data.
Below are pseudocode illustrating what I mean:
Using Service:
CODE:............
Make the functionality globally accessible in the custom Application object
CODE:...........
Weaknesses I can think of for the Service approach is complexity, since Binding is asynchronous. And it's very likely that I have to repeat some code because I have both ListActivity and Activity
For the Application approach, the documentation says not to rely on onTerminate() being called.

I'm pretty new to Android, and I had some questions that I've had trouble getting answered via the web. I have done a few searches, but I'm not sure how to word my question, either. So I apologize if this has already been covered somewhere...but here it goes. I was wanting to know how the Android handles application versions/ updates. Specifically, does an update blow away my database? Is there a way to preserve the users' settings as well?

I am trying to track down a rogue application that seems to be receiving massive amounts of data. On the iPhone, I would use about 200mb/month due to WiFi at work and at home. However, on the Samsung Captivate, I can go from 100MB/month to 2+GB/month! I noticed huge amounts of data being used on my commutes to and from work.
On occasion, my home WiFi/DSL would get so lagged due to my Captivate being on the network that my son would complain and I would then put the phone in air plane mode. I reasoned that if it was happening on my WiFi network, as well as 3G, then perhaps I could using my router to log the activity to see what sites my phone was trying to connect to, then perhaps I could pinpoint the offending application.
My phone was connecting to a website that was part of a posting that was on facebook, which was only showing on the Samsung "Feeds and Updates" widget. I wasn't running the native facebook application at the time. I had the "Feeds and Updates" widget set to never update, unless I manually did it. Why was it trying to connect when it shouldn't have been? Don't know. Am I certain that this widget was the offending application? Not sure. Since removing the widget, I haven't had any bandwidth spikes.
PS. I tried Droid Wall, but it fails to work.

From the People widget or "contacts" there is a tab that has Facebook "updates and events". While this is nice I would like to clear out the updates once I have seen them and can't for the life of me figure out how to do that. I don't use the auto update feature so when I press refresh I get everything which is fine but once I have seen them I would like to delete them off my Hero.

providing updates to unpublished application( old users)
Lets say we have a PAID app - "x-some". 1000+ users downloaded and using it, before 28-Feb-2010. we stopped for some reason from 01-march-2010, by "unpublishing the app" from market.
however, we found some bug in x-some and want to fix it and also to be available to only 1000+ users who already downloaded it. We dont want this app to be seen by new users. Only old users( who downloaded this paid app), should be able to view it and download the new fix.

I seen to have a problem installing and updating pretty much all apps from the market. I am running anbranded and unrooted desire on 2.2. I have successfully downloaded nearly 50 apps from the market but recently it doesn't seem to install any apps including updates. I did find one that was ok (retro camera which I tried just to see) but it wont update sppedview, folder organizer lite or quick system info pro. It also doesn't seem to want to let me install quite a few other apps that I have tried (some alarm apps and some poker ones).
