I have looked at every discussion and thread I can find on getting this to work but it is not. I have a simple timer that updates a text view (mTimeTextField in the example below). The mUpdateTimeTask run method is being executed correctly (every second) but the UI/text field is not being updated.

I made a simple countdown timer and it works as expected when plugged in via usb for debugging but when I take it off debugging and the screen goes off either time out or power button the handler fails to fire at the end time. I have created a custom timer class that gets created from the main activity when needed, because its able to have multiple countdowns running at the same time. Am I right in thinking that the handler just gets paused when the screen goes off and if so what are my alternatives. The activity is still in the foreground and I assumed the handler would still fire if the screen goes off.

However, during the time between open and close, there is possibly another animation triggered by a click...my question is, how would I cancel the "close" animation in the handler?

I thought this could be accomplished as follows:

I need to update my ui for an android app and I'm trying to use the Handler class to do it, using http://developer.android.com/resources/articles/timed-ui-updates.html and the android developer resources "Common Task" for using Handlers as guides.
Basically, I need something between the two - a timed update of the user interface, but without a button. So here is the relevent code that I am working on.

I seem to be having trouble with updating a TextView from a thread. I have a GameConnection class (which manages a socket connection) which I want to use across activities. It calls a local "onMessage", which then uses the target handler to call dispatch Message. The "Handler" in this case, is in my GameBrowser activity.
Here's code from the GameConnection class.
CODE:......
As said above, a local method "onMessage" method handles dispatching of the message.
CODE:.......
However, when I get the response in the GameBrowser class, I get a CalledFromWrongThreadException . Initially, I was using a callback method, which of course wasn't working. So, after some research, I've found that I have to use a Handler, but I can't seem to get it right.

I try to make several connection in a class and update the multiple progressbar in the main screen. But I've got the following error trying to use thread in android : Code: 05-06 13:13:11.092: ERROR/ConnectionManager(22854): ERROR:Can't create handler inside thread that has not called Looper.prepare() Here is a small part of my code in the main Activity.
public class Act_Main extends ListActivity

public void onCreate(Bundle savedInstanceState)
{ super.onCreate(savedInstanceState);
// Set up the window layout

I tried the following from an activity:
@Override public void onPause() { super.onPause();
postDelayed(new Runnable() { public void run() { mTextView.setText("I am paused!"); }, 10000); }
The activity, while in the background, still executes the runnable. Is this incorrect? Should we absolutely call removeCallback() from our onPause() handler to ensure that no postDelayed() runnables execute if we get paused? Or is it necessary to do this only in onDestroy()?

Just got a new Android phone, my second after a brief stint with the G1 a year or so ago..
Today I noticed that I received notifications that I have apps with updates available. When I click on the notification it takes me to my downloads in the Marketplace, but it doesn't show me which app has an update. They all just say Installed.
Is there no way to tell what application needs updating?

My array clearly has been updated, and I can see the change when my app starts, but why doesn't it update in this method? The code enters this method.
I have this code for update:
public Boolean update() {
try {data.put(Contacts Contract.Groups.SHOULD_SYNC, true);
Content Resolver cr = ctx.get Content Resolver();
Uri uri = Content Uris.with Appended Id(Contacts Contract.Groups.CONTENT_URI, Long.parse Long(get Id()));
int mid = cr.update(uri, data,_ID+"="+get Id(), null);
// notify registered observers that a row was updated
ctx.get Content Resolver().notify Change(
Contacts Contract.Groups.CONTENT_URI, null);
if (-1 == mid)
return false;
return true;
} catch (Exception e) {
Log.v(TAG(), e.get Message(), e);
return false.
i have an android app, with a actitity, that shows a map, with a position. This possition is updated on sharedPreferences with a service... ok, that works fine. I need that my activity implements runnable to be a thread that read's the position of sharedPreferences each 1000ms and then update the item position on the map... but it doesn't works. As i saw in debug mode, my thread doesn't work fine, ONLY ENTER ONE TIME on RUN() method... i mean that never enters into RUN() method again, only one time, cause this, the positions doesn't be updated on the map. What is wrong? why this thread doesn't work fine?
public class Locate extends MapActivity{
private TextView userText = null;
private TextView permissionText = null;
private TextView lastUpdateText = null;
private Button locateButton = null;.............
I will try to explain a simple app scenario: My app goes right to a 'main view'. In this main view I have inserted a 'TextView' which displays current settings created by way of the PreferenceManager. For simplicities sake, let's say I have a checkbox in my settings. When I first start my app - the TextView on my main view shows my checkbox setting correctly (true). Now I go to the settings menu, it pops-up, and then I change it to false. I go back to the main view and...no change. It still say's true even after I changed it to false. If I end the app and then re-start it - all is well and it shows my change.
Apparently the main view just stays in the background while I'm changing settings? How can I redraw or update the main view after I change settings?
Ever since the last couple of Google Maps updates my Latitude no longer updates on its own. All settings are set correctly to autodate and use GPS but no go. Only updates when I open Latitude manually.
View 2 Replies View RelatedI have become accustomed to checking my "Up time" and "Awake time" when checking my battery level. I have noticed that since I updated to 2.2 that the awake time runs continuously and I cannot figure out why. I am guessing that it reset some option when I updated, but I dont know which one. The battery will usually last from 8am until at least midnight, so its not a huge problem but if I can stop it and lower the Awake time and have it last longer I would like to do that. Right now I am at about 70% battery level with 5:54 Up and 4:16 Awake. Has anyone else experienced this or know that the issue might be?

View 6 Replies View RelatedI just got my Xperia x10 mini pro today and so far I have noticed that my email doesn't update itself, I have to do it manually but it seems like the phone should be able to do that. I use a hotmail account on my phone and I would like to know if the email can update itself, if I have to wait for 2.1 to have this problem resolved or if it's just something that I'm missing. And sometimes the phone will say "Does not connect" when I do try to update it but it hasn't done it in the last few hours. In addition, there isn't any change in my real email account. I could read an email on my phone and still half an hour later that very same email will be considered new and unread. Is there any way to solve these issues?
