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?

In my application I would like to catch all exceptions globally - it should not matter, where those exceptions occur. Some runtime exceptions are practically impossible to catch (OutOfMemoryError for instance), but I want to show an informative dialog and resume execution at some well-defined point (main menu activity or something).
Using Thread.setDefaultUncaughtExceptionHandler() does this for background threads, but it is of no help in the UI thread (or adjacent handlers). If an exception occurs in the UI thread, the UI will be jammed - not reacting to any key or touch events anymore. Of course, this seems natural since it did not catch that exception; but I wonder if there is a way to recover the UI thread. So:
- Can I recover / restart the UI thread after an uncaught exception (from another thread) ?
- Is there another way to catch uncaught exceptions globally ?
- Are there viable alternatives to handle this problem ?

My mClient get method is a simple HttpClient execute with an output buffer to read the input stream, so it's very trivial. Everytime I execute this task UnknownHostException will be triggered which will in turn call onTaskError on my currect Activity, but I still get a RuntimeException, but I don't see why. Maybe it's because it's late and i've done about 12 hours of writing code so it's something simple I just can't see?
I've a piece of code that launches an Intent. I'm wondering if there's any way to get return codes and/or catch exceptions? The particular scenario I'm facing is when I launch an Intent passing a 'rtsp' URL but it turns out the URL isn't available.

View 3 Replies View RelatedOk, 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.

View 1 Replies View RelatedI 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 want to show a simple toast, when exiting an application. The problem is, that the toast is not shown. I assume it is because the acitivity is finished or because of System.exit(0), but I don't know how to solve it. Does anyone have a tip?
In my activity I have the following 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 working on learning Android programming. I am attempting to build an app that shows a list of items, and when the user clicks on an item, it will display an image of that item, as well as information about it. I'm not sure the best way to present this information. Would using the Toast widget be best? Or TextView? Or, is there another way, like creating a new activity, that makes more sense?
After the user clicks on the list item, and reads the presented info, they should be able to return to the list.
When using setDuration for a Toast is it possible to set a custom length or at least something longer than Toast.LENGTH_LONG?

I am wondering if anyone has found a "work around" to this button. I dont want to have to press the button every stinkin time i open an email. Is there an app, or setting, or magical spell that i can perform to make this option go away so that when I open an email it shows me... the email (as it was intended to be sent)?

Code:
<PreferenceScreen android:title="@string/wifi_display_settings_title" android:key="wifi_display" android:fragment="com.android.settings.wfd.WifiDisplaySettings" />
But there is no wifi_display setting..
Is there a method to activate the desired option? Maybe it is only hidden and I have to unhide it.. I installed an app to show the wfd dialog, works fine. But I want the android settings way to do this..
I am trying to write a code about catch lat. and long. points with the GPS, actually I am using the shell with the commands "geo fix" because the DDMS doesn't work in linux apparently, I am using this scripts:
getBestProvider(criteria, true); getLastKnownLocation(provider); requestLocationUpdates(provider, 2000, 10, locationListener);
The questions is: the program is working right now in the emulator, but what about if I move the program to the real cellphone? Is the same? I need think in something else?
I am (supposedly) catching NullPointerException and returning 0 if that happens. But occasionally I get NullPointerException failure anyway. Is catching it this way no enough to prevent this failure?
private char getCharBehindCursor (int offset){ // get a single char behind cursor + offsett CharSequence cSeq; InputConnection inputConnection = getCurrentInputConnection(); if (inputConnection != null){ try { cSeq = inputConnection.getTextBeforeCursor (offset + 1, 0); } catch (NullPointerException npe) { /* failure*/ return (char)0; }
if (cSeq.length() == offset+1){ return cSeq.charAt(0); } } return (char)0;
I have tried all day to capture a trackball event in a View. Basically I want to use the trackball to move a Sprite in a 2D game left and right. The onTouchEvent works perfectly well in the View to move the Sprite with my finger but it would be nicer and cleaner to use the trackball.Can anyone provide me with a simple example that uses the trackball to move something in a View in a 2D type game world (not a menu or UI type of example)? Or can someone explain what I'm not doing. Thanks so much for any help you can give me.

Here's the corresponding part of AndroidManifest.xml:
CODE:............
Now, open a page with a link to an .exe file, click it. The download manager starts and then tells that The content is not supported on the phone. My activity doesn't even get called.
The questions are:
1) Why doesn't my activity get called?
2) What's the correct way of letting download manager do it's job and then get notified upon file download completion?
