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 am writing an application to upload a file from Android phone to a web server. I have tried the example from:
http://www.anddev.org/novice-tutorials-f8/doing-http-post-with-android
But it will only work for SDK 1.0 (why? Not Sure?).Can this be done for Android 2.1? Or is there any other method to load a file from Android to a webserver?

I have some reference data in a text file (~5MB) that I want to use with might android application.The file is of the format:
1|a|This is line 1a
1|b|This is line 1b
2|a|This is line 2a
2|b|This is line 2b
2|c|This is line 2c
What I want to know is the most efficient way (less memory, fast, size etc.) to use this file within my application.
a.) Should I save the file as a raw resource and open and read the whole file whenever I need a certain line.
b.) Should I convert the file to XML and use XPath to query the file when ever I need to look up a value
<!--sample XML -->
<data>
<line number="1">
<entry name="a">This is line 1 a</entry>
</line>
</data>
c.) Should I just copy & paste the whole file as a static string array in the application and use that.
[EDIT] I will also need to search this file and jump to arbitrary keywords e.g. "line 1a".

View 1 Replies View RelatedI 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.

View 3 Replies View RelatedI'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.
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?
View 1 Replies View RelatedI 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.
View 1 Replies View RelatedI 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
*/..................................

View 1 Replies View Relatedi 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?
View 4 Replies View RelatedI'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.
