Android :: Smack & Xmpp / Handler - Propagate When Receive Message
Oct 7, 2010
connect / login are executed in the same thread of the caller, then are blocking - The packetlistener callbacks are called from smack receiver thread - The sendpacket enqueues the message to a queue. when I receive a message, I need to propagate it. I can use an handler, but it only gets the runnable object. How can I pass the data to the runnable called by the handler? I can't use a local variabile, because if I receive a lot of messages it will be overridden and I will loose some of them. Is it ok to use a queue to feed the runnable? Are there other techniques?

I am working on a XMPP client on Android, using the Smack library. The roster/messaging/presence stuff is running very well. However, I didn't find a way to store additional profile information (userpicture, the dogs name, ...). The only way I see from googling is using VCards. But it simply did not work. I tried the following:.................

I have an app with a two threads - main and data loader. When data loader finishes it posts a Runnable object to the main thread (as described in the DevGuide), but it never gets delivered and run. Here's the basic code:
class MyApp extends Application{
public void onCreate()
{LoaderThread t = new LoaderThread();
t.start(); }
private class LoaderThread extends Thread {
public void run()
{ SystemClock.sleep(2000);
boolean res = m_handler.post(m_runnable);
if(res)
Log.d(TAG, "Posted Runnable"); } ............

I was curious about the nature of the handleMessage() and sendMessage() behavior of the Handler class. I want to be able to send message to another thread in such a way that the destination thread can process the message queue when it wants to. It seems, however, that the message is processed by handleMessage() practically as soon as it's sent.
I'm trying to design a game loop thread that does something like this:
CODE:.....
However, I as soon as sendMessage() is called (from the parent/calling thread), the Handler.handleMessage() is processed (in the child/receiving thread), even if the child/receiving thread is blocking in a while loop.
I've seen this problem solved in other games by using a thread-safe list (ConcurrentLinkedQueue). The UI thread just posts events to this queue, and the game loop can remove the events as it seems fit. I just assumed the Handler class was designed for this purpose. It seems it's more intended for asynchronous callbacks to the parent thread.

I am using an Executor [fixed thread pool] with my own ThreadFactory that adds a Looper:
CODE:...............
I am running a thread that makes network requests but if the network fails I would like a dialog message to be displayed to the user. This process is rather involving since it requires making AND displaying the request in the UI thread. I can wait for the user's response to the dialog by simply adding a Loop to the network thread and wait for a message to be send from the UI thread. This allows me to encapsulate the network requests in a while(tryAgain) thread. All works well except when the Looper.loop() method is called the second time (after a second network error dialog is displayed) and a message is sent by the dialog (in the UI thread) to the network thread's handler:
CODE:.............
In the AlertDialog instance is an OnClickListener:
CODE:...............
I've checked that the thread is still active with handler.getLooper().getThread().isAlive() which always returns true but it still gives me "sending message to a Handler on a dead thread". How is it that the Message/Handler has decided that the thread is dead? Shouldn't it rely on the .isAlive() method? In the end I am trying to avoid replicating the thread management build into the Android OS .

I have attribute "attr1" defined for my views A, B, C. A and B are actually ViewGroups. Let's say C is contained in B and B in A. Is there an existing mechanism in Android framework that allows me to specify the value of attr1 in A and have it automatically propagated to B and C?

Is it possible to receive SMS message on appWidget?
I saw android sample source(API Demos).
In API Demos, ExampleAppWidgetProvider class extends AppWidgetProvider, not Activity.
So, I guess it is impossible to regist SMS Receiver like this code...
My goal is to receive SMS message on my custom appWidget.

For starters, the phone is amazing. I just have a few questions: Is it possible to set a ringtone to go off when you receive a text message? MY old VZW phone allowed a ringtone notification. I have yet to find a way to do this; anyone know how?

I'm developing a google maps based application for android 1.6.
My problem is that in my application I have more than one layer that extends from ItemizedOverlay representing information in the map.
The problem is that all the layers implement the onTap method, but now only the last layer (on the top of the stack) detects the tap event, so If the user taps on an item that is in a deeper item the method onTap never fires.
Is there any way to propagate the event to deeper layers?

Usually my phone is on silent, and last night, I turned the ringtone volume up. So, I set my notification sound when I receive a message. Whenever I receive a message though, the sound is VERY faint and almost silent. The media volume is all the way up... Is this a phone or Handcent problem?

I was wandering if anybody could help me with the email notification problem im currently having. Iphones and blackberrys all give you a notification when you receive a new email or a new facebook message. The galaxy s does nothing when you receive a new mail. In settings you can select a ringtone, set it to vibrate when you receive a message. But nothing happens. The only way to find out if there any new messages is by clicking on the email app ( in which i am using hotmail).

So I've had my Samsung Moment on Sprint for 2 days now and a problem started happening today. Whenever I receive a text message, the phone goes black, locks, the ANDROID screen then displays and the phone goes back to normal but begins looking for service.

I'm using Google voice exclusively for text messaging. Right now the only way to send/receive texts is to use the google voice app, but I would like to do that through the native message app.
