Android :: Periodically Check If GPS Get New Data
Jul 25, 2010
I have successfully been getting GPS data through the registerLocationListener() and onLocationChanged() methods. The only problem with this is that the speed reading of my app freezes if there is no more GPS data (e.g. when I go indoors, enter a tunnel, etc). The behavior I want for my app is that the user is somehow notified that the speed reading is probably not accurate due to a lack of fresh data (set speed to zero, blink the speed reading, etc). How can I do that? I though of checking periodically whether the GPS unit was detecting any satellites, but I'm not sure how to force periodic checks.

We have a very patchy wi-fi network here. The wi-fi router's pretty old and I tend to need to switch it off and on every couple of days. Is there an app I can use that will - perhaps in conjunction with Locale so it only runs when I'm in the office - periodically check if our wi-fi connection is up and running?

I working on the app where I get the data from the server using rest call and add it to the view. I get all the initial data correctly. I use AsyncTask for doing it. Now I want to periodically (say 2 mins) fetch the new data from the server and add it to view.Periodically fetching data (polling) from the server in Android.

Finally got Velocity installed and setup the way I like it. It's a tremendous improvement in overall performance compared to the stock. Kudos to Trident for taking the time to put this together for all of us. I only have one problem with it that I hope I can do something about or I may end up back on the stock ROM. Velocity comes with the latest Google maps version, which I hate because you can't clear the data so over time the app builds up more and more used space. Since I use the Google Maps Navigation pretty much everyday for work, that's going to be a small problem. Does anyone know if there is an app out there that allows you to clear the map data periodically? Or is there a way I can push the stock Map app into Velocity and do what I did before and simply ignore the update notices? I know I can just keep uninstalling it and reinstalling it periodically and i may end up doing that if there is no way to clear the data because I would really like to keep Velocity. I hope this doesn't come across as a knock on Velocity because it's not meant to be. I think it's a tremendous upgrade to the Ally and if it wasn't for my unique situation of using Google Maps so much, I wouldn't even be asking.

I have google voice. And the quality is excellent but im on a non data plan so I can't check it out in 3g. I live in a t-mobile edge zone so I want to know about the voice quality & reliability cause I'm planning on getting a nexus with a t-mobile data only plan. Will it be like a regular phone call or will I have poor quality?

So , i want to be able to intercept a click on a button of the EditTextPreference , check the validity of the data and if the data is incorect , display a message to the user and come back on the EditTextPreference.
What would be the best way to achieve that?

I'm doing Major Project on my final year and I'm very new to Android plus I;m not good at codings. I need help with my login page. I've created something like a database connection java file which is this:
CODE:......................
I've already created a database for users using SQLite. The database name is Users and the table is called User. The records inside the table are Username, Password, LastName, FirstName. I've inserted one user's info into the database. The problem is I do not know whether my UserDB.java is correct.
And I've also created login.java. Hardcoded Login page:
CODE:........
So I want to know how I should apply the database connection on the login.java. Should I insert database connection something like db.Open();? I studied ASP.Net a few months back and I kind of forget most of what I've learnt.
So how should I open the database connection on login.java and how to check with database whether the user enters the right username and password?
Just incase you need my xml, here's the code:
CODE:......
I need to learn how to do it so that I can apply for other pages for example Register.java page.

I went into Weather Bug (free version) to check the weather and accidentally hit the menu button. Decide to check preferences for the heck of it and I see "Enable Updates' set to yes and Update Interval set to every 1 hour. What?? I know it's probably not a huge drain - but I had no idea that it was checking on a regular basis (and why I don't know). So please check your apps to make sure they are not updating data auotmatically! After that I went into every app I had to make sure I was either signed out or or set updates to manual.

I'm developing sort of a wireless scanner, so I need to scan every X seconds. I know I should use WifiManager and startScan() to get the networks and then register a receiver to receive the event once the scan has finished. However I'm having problems when trying to figure out how to scan periodically. It's more like a design problem. My solution so far has been to create a Service which takes care of the scanning, besides the main Activity.
I think this is correct. So, how could I tell this Service to scan every X seconds? I've thought it may have a Thread object, call its Scan method during tart_services() and then take it to sleep. Also I thought I could just get rid of the Service and run the Thread from the main Activity, but then I guess it would die whenever the Activity is not visible. None of then seem like a really good solution to me, and I think there must be an easier way to do this.

I currently use SMS Backup & Restore, but that has two drawbacks I see
-I have to manually initiate the backup
-It only stores and restores one file, so I have to overwrite and rename
I just lost my texts and only had a two day old backup. I'd love to see the same thing but that can do it with a timestamped file such as backup_2009-12-18-15-08.xml (pickable when restoring) and can run at a preset time each day or each half day.

I have one activity. OnCreate the activity gets the source (html) of a web page to a string and presents the result (after parsing it a bit) in a textview. I would like the activity to reload/refresh periodically to always present the latest information.

If I want to upload a text file containing some game stats to a web server for testing purpose, which approach is the best? Do I write a service along with my application and then upload the log file once it reaches a specific size? Or do I embed the logic into my application and then do it during idle times?

I never got this working in a straightforward manner. Sorry if I'm being a little vague. I'll try to elaborate on what I'm trying to do. I am trying to build a listview that grabs its data from a webservice. Once I initialize a listview, I want to keep polling the webserver periodically and update the contents of the listview. For this I am doing something like this:
public class SampleAutoUpdateList extends Activity {
//Autoupdate handler
private Handler handler = new Handler();
private Runnable updater = new Runnable() {
public void run() {
/*
* Update the list
*/..................................

I have an app that needs to send a periodic heart beat to a server, but when the phone goes into standby mode the background heartbeat thread dies. Is there anyway to wake the phone from standby, send the heartbeat and then go back to sleep programmatically? I want to avoid using PARTIAL_WAKE_LOCK if possible.

i have a application that displays tasks and i created an option in the Settings menu that lets you choose in how many days all (Never, 10 days, 20 days or 30 days) these tasks should be automatically deleted. So when i open up the app there will be a method that will be called and check if theres any tasks to be deleted. I did that to challenge myself, but i'm hitting the wall with my head and i cant come up with something. So here i am in need of help! A little more information: i was trying to do something with java/android code, but from past searches i saw people dealing with it using SQL functions. Is it better?

I'm coding an audio player where a thread updates the TextView representing the track's elapsed time, every 250 milliseconds. The display looks like this:
1:30/2:30<-----Progress Bar----->
TextView 1 is 1:30/ and TextView 2 is 2:30.
Both are set to wrap_content for width.
What happens is that on every 250 millisecond cycle, the thread checks the current time and updates TextView 1. For this brief moment, TextView 2 and the progress bar get pushed momentarily to the right by about 2-4 pixels. Then they come back to place until the same thing happens during the next cycle. I don't know what's happening. There are no trailing space characters, etc and everything should, theoretically, be working smoothly but it's not.

I have a Desire on Vodafone in the UK. Upgraded to Froyo using the official method the other week. Not sure if it is since then, but it's happened a lot the last few days, and it definitely didn't do this before the upgrade, but it seems that my Desire is now turning on GPS every few minutes - the icon flashes away in the notification bar. I have no idea why. Any idea what's happening, and how I can work out what app is causing this?
