Android :: Display A Toast From An IntentService?
Jun 11, 2010
I have an IntentService that handles button callbacks from a widget. When the user presses a certain button, I want to display a Toast. I return from onHandleIntent almost immediately after doing Toast.show(), which in turn stops the service and kills its thread, which keeps the Toast from actually being displayed.
Can anyone suggest an easy way to get the Toast (or something similar) to display from an IntentService?

I have an IntentService that downloads some files. The problem is that I create a Toast inside the IntentService like this
Toast.makeText(getApplicationContext(), "some message", Toast.LENGTH_SHORT).show();
The Toast will never disappear event if I exit the app. The only way to destroy it is to kill the process.
What am I doing wrong?

Ok, I've tried two examples of AlarmManager- one from the commonsware website, and one from the manning website. The code I am currently working with is from the manning website : [http://unlocking-android.googlecode.com/svn/chapter8/trunk/SimpleAlarm/][1] There are two classes, AlarmReceiver and GenerateAlarm. Anyone have any idea why the toast will not display in the emulator? I was thinking that it was because I am located in the Eastern Time Zone and it uses UTC, but I have fiddled with different things and none of them seem to work.

I have a Activity called main. If I call Toast.makeText(this, "Hello World from main", Toast.LENGTH_SHORT); this works fine. However, for every other activity in my application, I cannot display a Toast. No exception, nothing in the Log but I don't see the Toast. Code...

I looked for any information about onTap event processing for itemized overlays in this group. There is a lot of useful information but I could not find the answer to one question.
The tutorial by Mark Murphy on itemized overlays, http://androidguys.com/?p=1413
describes how to generate a Toast message whenever an onTap event occurs. In his case, the custom itemized overlay activity is included in the main activity. In my case, it is not. My custom itemized overlay activity is included in the application package as a public activity.
This means that the line Toast.makeText(NooYawk.this, items.get(i).getSnippet(), Toast.LENGTH_SHORT).show(); will not work "as is".
I have had trouble in correctly identifying the context for the Toast. Attempts to use the main class' (the one calling the custom itemized overlay class) context have not worked. I would appreciate it if anyone could suggest how I could resolve this issue. Incorporating the custom itemized overlay class in the main class is not a desirable option.
Alternatively, I would appreciate any suggestions for generating a display of the title and/or snippet information for markers on a map.
The onTap event works fine (Log.i statements in the onTap method display the correct information for each marker tapped)

I am writing my own SMS application that will display a toast of my message once it arrive. Now is it possible to delete the message after the display of the toast, so that it will not go into the native SMS application?

I noticed that a toast isn't displayed when it's used inside a catch block.
Does anyone know how to show toasts when catching exceptions?

We are in the process of refitting some of our recievers and services with IntentServices (mostly to address rare ANR issues - and because IntentService is pretty cool...). In one case we are converting a traditional service to an IntentService. The original service fired off a few methods whose job was to download data from our servers. Each of these requests would spawn a thread of their own to do the work (apparently not fast enough to avoid the occasional ANR). So now we have a question concerning the life cycle of these processes.
For example, the following situation demonstrates what is happening:
- Start Intent Service - Trigger Download1 - Download 1 thread starts - End Intent Service
- Download 1 thread continues..... - Download 1 thread ends
Our question concerns our exposure to the OS shutting down the Download 1 thread because the Intent Service has terminated before it finishes up. Not sure if it is becomes more or less likely that the OS will view it as something that can be flushed.
If the Download 1 thread is more likely to be flushed by OS we will need to take a different approach.

I was wondering if it is possible to set the priority of an IntentService like you can with a Thread. So far I have not found anything.

I have to process some events given by a broadcast receiver. As kindly suggested by Mark M. a week ago, I am trying to send the intent to an intentservice in order to pass the data to be processed to another thread.
Looking at the doc, I can read abot onHandleIntent: "Only one Intent is processed at a time, but the processing happens on a worker thread that runs independently from other application logic. So, if this code takes a long time, it will hold up other requests to the same IntentService, but it will not hold up anything else.
What does it mean? Will the intents be queued and then processed one by one, or does it mean that the startService will block if the intentService is busy processing a previous intent?
And more (this is just my curiosity): What is the point in having a onStartCommand method in IntentService if the Intents must be processed in "onHandleIntent"?

The new IntentService in Android 1.5 looks excellent for handling AlarmManager-initiated broadcasts for scheduled WAKEUP work...except I can't see that it uses a WakeLock anywhere, either in itself or Looper/MessageQueue.
Does this implicitly hold a WakeLock that I'm not seeing? Or would I need to create a WakingIntentService that has an active WakeLock so long as there are messages in the queue?

I have a service that runs in the background. I´d like to be able to show a message to the user when there is an incomming call. Atm i´m using a Toast, because as far as I know it is the only way to display something regardless of the current activity the user is running. But I have seen apps that can show entire views on top of others activities. How can this be done?

Is there anyway I can tell a Toast Notification to show up only for a specified amount of time. Generally shorter then a regular toast message.

I have a listview in my Android Application. Now, when the user presses Next Button other contents will be loaded into the listview. What I want is that if there are no more contents available then there should be a toast displayed indicating that there are no more data available.
Say, for example I have a total of 55 data available and I am displaying only 30 of them in one listview. So, when the user presses Next for the first time next 25 records will be visible. If the user again presses the Next button then a toast should be displayed on top of the last listview that had last 25 records.
Currently I get an error as IndexOutOfBoundException : Invalid location 15 size is 1.

My user hits a button and kicks off a process that takes 3 steps in about 10 seconds total. I'd like to pop up Toast messages "Step 1", "Step 2", "Step 3", "Finished!" as the process progresses. I'm using the standard Java Thread interface to run the process in a thread and I've found that trying to pop up Toast from the thread causes an FC. What is the best way to report this kind of progress - step by step messages?

I am slowly trying to figure out maps... I want to be able to click on a point and pop up a message. Toast seemed the way to go. So I added an "onTap" handler in my class that extends ItemizedOverlay (the class is called HelloItemizedOverlay) and then tried to grab the Toast example... But I am seeing Eclipse tell me that the line is in error no matter what I do...
My code is below:

In my application I've implemented such that pressing the hardware volume keys displays a Toast with the current volume. Things go well most of the times. However long presses of the volume keys do succeed in crashing my application. The Log generated on crash is the following...
The approach I follow:
I have a toast Object and for every key press event detected I inflate a view ,set the view elements within, set it to the toast and then show the toast.
Any idea what is going wrong ? code...

If there was a way to display all text in a toast to be centered. For instance, I have a toast that has 2 lines of text in it. For purely aesthetic reasons, I would like the text to center-aligned instead of left-aligned. I've looked through the documentation and can't find anything about it. Is there a simple way to do this that I have missed?
