Android :: Way To Refresh An Activity / Map View Refresh Fails?

May 3, 2010

After implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no idea how to tell the map activity to refresh on its own and display the new coords. the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view?

Android :: Reload Activity Data

May 23, 2010

I am writing an Android app, part of which will be a survey involving multiple pages of checkbox question and answers. I have created an activity to display the question and options (from the DB) and what I want to do now is when i press the "Next" button it should just reload the current activity with the next question set from the database. (the activity starts with survey.getNextQuestion() - so its just a case of refreshing the activity so it updates)

Android : Force An Activity To Reload Completely?

Jul 19, 2009

I have an application, where I need to change the language through a settings menu. Now this part works perfectly, but it doesn't change the language for activities that have gone through onCreate.

I got a TabHost, and 2 tabs in it, from the tabs you can get to settings.

Refreshing the TabHost isn't an issue, as it's fairly small, however both the 2 tabs are quite large views, and having a function to manually update all the strings seem unnecessarily difficult. Is there any way to force the activity to recreate itself and trigger a new onCreate?

I tried having a static function in the tabhost that clears all tabs and recreates them, this refreshes the tab titles, but not the content in the tabs.

Android :: Changing Locale - Force Activity To Reload Resources

Apr 15, 2010

I have a language setting in my application. When the language is switched, I would like all the textviews etc to change language immediately. Currently I just change the locale in the configuration, so the language has changed when the user restarts the activity.

Solution to my problem would be to make each textview load the new resources each time the language is changed. Is there a better solution? Perhaps a neat way to discretely restart the activity? Or maybe just force reload of the resources?

Aug 12, 2010

I have a START and STOP button in the main screen of an App. there are some GUI and threads that are instantiated when I click on START. When I click on stop, I want everything to be stopped and the activity should come back to its origin state. To the state that is exactly same like when launched (when we tapped on App icon in mobile).Is it possible to do this? I tried with finish() , this killed the app and exited . I don't want to exit from main screen. rather, on clicking STOP I want app to come back to origin or born state.

HTC Desire :: GPS Periodically Turning On?

Sep 4, 2010

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?

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.

Android :: Scanner For Wireless Networks Periodically

May 26, 2010

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.

Android :: Backing Up SMS Periodically (possibly Timestamped)

Dec 18, 2009

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.

Android :: Make ListView Update Itself Periodically?

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
*/..................................

LG Ally :: End Up Back On Stock ROM / Clear Map Data Periodically?

Oct 8, 2010

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.

Android :: Calling TextView.setText() Periodically Causes UI To Jerk

Sep 28, 2010

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.

If I put my phone down for >1 minute and go straight back to it, I really shouldn't need to go though security, whereas if the phone has been inactive for, say 15 minutes, then going through security makes sense. Is there a way to delay the lock?

3 Is there a way of cut and pasting from a gmail?
4 Is there a way to make a calendar alarm sound periodically, x number of times?

Android :: Storing A User Selection That Stores Itself For Use On Reload In App

Aug 2, 2010

I've built a dialog that asks the user to pick a city from the list provided when the application first opens. The dialog works perfectly, however I want to store the user's choice so that when the app is opened a second time, it checks to see if the user has already made a selection previously. If they have, it doesn't display the dialog and defines the city variable as their previously chosen preference. And obviously, if they haven't made a selection previously (because its their first time opening the app or for some reason the app couldn't read the stored preference), it displays the dialog.
