I have a problem regarding my intent. It seems that my app crashes when i select the intent. I found the line of error code due to the stack trace. But i couldn't find anything wrong with it. Hope anyone can help me with this.
This is the java code in line 121:

I'm trying to have my app display my login activity when a user selects add account in accounts&sync or wants to use the app and isn't logged in yet. I've followed the example SampleSyncAdapter fairly closely, but can't get it to work.
In my auth service:
CODE:........
In my manifest:
CODE:........
In my main activity:
CODE:.......
I've tried doing both
CODE:.......
And
CODE:............
Before the startActivity() call, but it still can't find an activity for that intent. If I try to add an account via accounts&sync the app crashes with the same ActivityNotFoundException.
I've examined c99's last.fm app, which defines a custom action and uses intents based on that action rather than android.accounts.AccountManager.ACTION_AUTHENTICATOR_INTENT. Is that a better approach? Is there a way to make it work with Accounts & Sync?
The JavaDoc of Context's public abstract void startActivity (Intent intent) said:
This method throws ActivityNotFoundException if there was no Activity found to run the given Intent.
But when I look at the android source code, it does not catch ActivityNotFoundException.
For example in AlarmClock.java:
CODE:..................
what is the code which handles the case when there is no activity for that intent?
I'm having difficulties handling multiple instances of my root (main) activity for my application. My app in question has an intent filter in place to launch my application when opening an email attatchment from the "Email" app. My problem is if I launch my application first through the the android applications screen and then launch my application via opening the Email attachment it creates two instances of my root activity. steps: Launch root activity A, press home Open email attachment, intent filter triggers launches root activity A Is it possible when opening the Email attachment that when the OS tries to launch my application it detects there is already an instance of it running and use that or remove/clear that instance?

Is there a way to prevent this dialog from displaying?
Is there a way to programming perform the button click?
Is there a way to programmatically close the dialog?

I'm writing a client application for an Italian social network (Meemi) and I'd like to give the possibility to users to share their calendar events via my client. I noticed on my device (HTC Desire) that is possible to access to a "share chooser" from the Calendar event list: in fact I can share via email, sms, and bluetooth. I'd like to add my client to the this sharing list: but I'm not able to found the right intent filter to use.
View 2 Replies View RelatedI have a TabActivity, and each Tab corresponds to its own Activity. In one of them, in the onCreate method, I use startActivityForResult to show a dialog (specifically, Bump's BumpAPI activity).
code:...............
The problem is that when the screen orientation changes, it tries to create the tab's activity again which makes another BumpAPI dialog, resulting in multiple stacked on top of each other. Do I have a hook into the started activity to cancel the previous one when the orientation changes?
A workaround seems to be to add a button that when clicked, starts the second activity, but that adds an unnecessary step.
Also, I can't fix the screen orientation for the entire tabActivity because some of them require typing and users may want to use their physical keyboards.
I am building an Android application that requires OAuth. I have all the OAuth functionality working except for handling the callback from Yahoo.
I have the following in my AndroidManifest.xml:
CODE:..............
Where www.test.com will be substituted with a domain that I own.
It seems :
This filter is triggered when I click on a link on a page. It is not triggered on the redirect by Yahoo, the browser opens the website at www.test.com It is not triggered when I enter the domain name directly in the browser.
When exactly this intent-filter will be triggered? Any changes to the intent-filter or permissions that will widen the filter to apply to redirect requests?
I create 2 simple activities, first activity is to login, after that proceed to the second activity. However, the intent is having some runtime error: saying that the sources is not found.
View 2 Replies View RelatedMy app works with pictures. It can take multiple pictures as an input, process them, and send them again to another app.
As a consequence, my main Activity has declared an intent filter on ACTION_SEND_MULTIPLE for image/* mimetypes and can result in issuing a new Intent with the same action and data type using Activity.startActivity(Intent).
Is there a way to exclude my own activity from the list of apps that is displayed to the user after the startActivity() call ?
I read here ( http://androidlittle.blogspot.com/2009/08/intent-filter-for-share-link.html ) what intent-filter is required to handle the "share link" intent that the android web browser sends.Can anyone tell me what I'm doing wrong? My main (launcher) activity works fine, so I assume there is no issue with installation on the emulator.
View 1 Replies View RelatedI am writing an activity, that loads data from a server and displays it as a list using ArrayAdapter. For that I'm showing a progress dialog i.e loading, while it loads all data from the server. Then i dismiss the dialog in a handler. My problem is that when ever i change the orientation, the progress dialog is again shown, which is not needed, because all the data is displayed already?

View 9 Replies View RelatedI have an Activity that will query a RESTful API every x seconds (polls using a handler). The results of the GET are used to update a ListView. This is done using an AsyncTask.
I want to put a Notification in the Notification bar when certain criteria are met in the new data. Everything I have read up to this point has suggested that notifications should be created and updated using a service so that the notifications can be made even when the application isn't in focus. I see the positive aspects of this.
However, I'm unsure if I should just create a service from within my activity or if I need to do something more complex than that. I'm undecided on if I should scrap my AsyncTask model in favor of using the Service to update my list view.
So, my questions are:
1) Is there a good tutorial showing how to make a local service from an activity?
The tutorial doesn't need to show how to make them communicate, the service could be isolated from the main activity.
2) Will #1 provide me with the notification benefits I'm looking for? (Notifications are generated even when the main app isn't visible)
3) Should I use this same service to update my listview?
The service would basically be making the same query that the AsyncTasks are, just doing different things with the results. The app would seem to make more sense to have the Service query, do notification processing, then give the results to the activity, but I haven't found a good resource that clearly demonstrates how to do something like this.

I'm having a couple of problems with an alarm app I am developing.
The first thing that I think is a bit weird is that when an alarm goes of and wakes the phone up. These things happend.
oncreate
onresume
onpause
onresume
Why are they run in that order? The last two should not be called? And this is what's causes me big trouble, because when i press home or back on the phone, onPause is run, which I want to call finish() from. And that part works as it should, but that does not work when the phone wakes upp from sleep bacause of the onPause call...
I need my Android app to save it's state to disk when its activity is put in the background or killed. It's been suggested that I start a thread when onPause() is called and perform any expensive I/O procedures there (see http://stackoverflow.com/questions/3894668/saving-loading-document-state-quickly-and-robustly-for-image-editor).
In what situations will the OS kill the thread and how commonly do these situations occur?
I assume it will be like how Activities are dealt with where the OS can arbitrary decide to kill the thread but will mostly only do this when resources are extremely limited. It would be nice to find some specific documentation of this though.
From playing around, with some test code, a background thread started in onPause() will run indefinitely in the background on my device (I tried loading lots of apps and couldn't get it to be killed).
For my specific app, I'm writing a bitmap editor where I'm using the Command pattern and the Memento pattern to allow undo and redo of edits. I'd like the user to be able to undo/redo their edits even e.g. the user gets a phone call and the activity is killed when it is put in the background. The best solution I can think of is to use a background thread to constantly save my command and memento objects to disk during application use and to finish up saving any objects that are left in a background thread if onPause is called. In the worse case, if the thread is killed I'll only lose some edits.
So today I had a bright idea to rename my packages, now my android application which I have schedule for release on Thursday is not working.
I am getting a similar error as follows:
Error: Activity class {org.me.androidapplication2/com.albertrosa.DEMO.MainActivity} does not exist.
I have modified the manifest to reflect the change:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.albertrosa.DEMO"
android:versionCode="1"
android:versionName="1.0"
there is more to the manifest but this is all that I have changed. is there something I am missing or doing wrong. I am using netbeans to build this app.
I am getting following message when i try to launch service.Also is there any specific path on file system where we need to place the .apk file which contains my serivce component only.
View 2 Replies View RelatedI have an Android activity which in turn starts a thread. In the thread I open a persistent TCP socket connection. When the socket connects to the server dynamic data is downloaded. The thread sends messages using Handler-class to the activity when data has been received. Now if the user happens to switch from portrait to landscape mode the activity gets an onDestroy call. At this moment I close the socket and stop the thread. When Android has switched landscape mode it calls onCreate yet again and I have to do a socket re-connect. Also, all of the data the activity received needs to be downloaded once more because the server does not have the ability to know what has been sent before, i.e. there is no "resume" feature.
Thus the problem is that there is alot of data which is resent all the time when landscape mode is changed. What are my options here? Should I create a service which handles the socket traffic towards the server thus I always got all the data which the server has sent in the service. Or should I disable landscape mode all together perhaps? Or would my best bet be to rewrite my server which is a VERY BIG job
I am playing with "android.speech.action.RECOGNIZE_SPEECH" and in the source it says to trap for ActivityNotFoundException. However, I am not sure how I can do this, the activity class doesn't support this event. I found it as part of android.content, but am not sure how to implement it. Multiple inheritance?
View 2 Replies View RelatedSuppose I have something like an alarm activity which launches the alarm through the lock screen, accomplished via
getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
Now, from here I could press the back button to kill the activity, but I also want a press of the lock button to silence the alarm. How would I go about creating a handler for presses of the lock screen button?

Is it possible to get the Activity from an Intent?
View 2 Replies View RelatedI'm switching between different Activities using Intents. For one Activity, I would like it to clear the history stack so when the user presses the back button, it takes them Home instead of previous activities in my application.
View 2 Replies View RelatedI've searched for a few hours for a solution to this, so hopefully this isn't a repost I'm setting a shortcut on the Home screen which raises an Intent to my application - the problem is that I don't want to show my app, just run a little code and display a Toast notification. This must be possible - I just can't work out how.. Once I'm handling the shortcut Intent in onCreate() the UI has initialised and I get a little screen flicker if I then run my code and finish().
View 4 Replies View RelatedI have a service that is downloading a file. When the download is done, I would like to update my "Downloaded files" list in my Activity, but only if the Activity is running. I do not want the Activity to start if it's not already running. I was hoping I could do this by making a new Intent with some special flag. Anyone have any idea how I can achieve this? A tiny code example maybe?
