Android :: AsyncTask - NDK - Neverending Process
Dec 19, 2009
I'm running a pretty weird setup:
AsyncTask1.class -> AsyncTask2.class ->AsyncTask3 (inner class of AsyncTask2) ->NDK call (this one takes a long time).
Since the NDK takes so long, I want to give users the option to kill the NDK call so that they can actually use the app. Basically, I keep references of all the asynctask instances and I do:
aSyncTask1.getAsyncTask2().getAsyncTask3().cancel(true);
The true means mayInterruptIfRunning
But, lo and behold, the NDK process is still running. I don't care how its done, but I need that NDK process to die when I ask it to. I'm thinking about kill-9 it through a popen call..

I'm trying to figure out the correct way to create an AsyncTask to retrieve some data from the internet and then to take that data and bundle it up in an Intent and pass it to a new activity(A list display). So in the first activity I just have an EditText and Button. In the event of an OnClick the task should be called and when it is finished the data should be bundled inside an Intent and passed to the next Activity. The problem is when I take the results from onPostExecute and set them to an instance variable of the main activity, that instance variable is still null when the task is complete. Here is the barebones version of the code:
CODE:...........
When I debug the application I see onPostExecute does contain a valid PlacesList full of results, so why is the instance variable places set to null after the task is executed? I am going about "returning data" from an AsyncTask incorrectly?

Sometimes the DDMS in the Eclipse not listing the process.
To do the debug in this condition,
1) Is their any way force the DDMS to list the process?
2) Any command to attach the process from the command line?

At a certain point in my program, when I'm completely done with my service, my activity executes unbindService() and stopService() -- yet the process persists. I can tell that it persists because I run "ps" in "adb -e shell":
CODE:.............
"adb logcat", I can show you the sequence of events:
ACTIVITY: context.unbindService(serviceConnection);
SERVICE: onUnbind();
ACTIVITY: stopService(serviceIntent); & returns true!
SERVICE: onDestroy();
First, my activity calls unbindService(serviceConnection). According to the documentation, unbindService() will "Disconnect from an application service. You will no longer receive calls as the service is restarted, and the service is now allowed to stop at any time." So that is fine, and it is happening.
Appropriately, we see the onUnbind() call happen on the service side. According to the documentation, onUnbind() is called when "all clients have disconnected from a particular interface published by the service." So this confirms the correct service connection is being passed, and that the service is responding accordingly.
Next, my activity calls stopService(serviceIntent), and returns true. According to the documentation, stopService() does the following: "If there is a service matching the given Intent that is already running, then it is stopped and true is returned; else false is returned." Again, this is happening and returning true.
In response, the service's onDestroy() method is called. According to the documentation, onDestroy() is "Called by the system to notify a Service that it is no longer used and is being removed. The service should clean up any resources it holds (threads, registered receivers, etc) at this point. Upon return, there will be no more calls in to this Service object and it is effectively dead."
At this point I expect the process to disappear from the process table. Yet it remains indefinitely. But why?
Also, the process is so persistent that I can bind to it again, and I see that it is the same exact process responding because the PID (process ID) is the same!

So, I decided to give Tridents ROM a try about 10-minutes ago.
I used ROM Manager, backed-up my old ROM, then downloaded Velocity 0.2.
Now, my phone will do nothing, it turns on and shows the red Droid eye, then when it's time to go to the home screen I get pop-up after pop-up saying that "The process com.android.phone has stopped unexpectedly. Please try again."
I have no way of getting on my phone at all, what can I do?

I Just installed a new theme (Live Wire) for my Lithium Mod Rom. Don't know if there is a connection, but when I need to update an app, I get the message something like "process android media process stopped unexpectedly" and it will not allow the update. Everything else works well. I have turned it off for awhile, and have done a battery pull.

Every 5 minutes this error pops up "Sorry! the process android.process.acore has stopped unexpectdly. please try again." It doesnt actually close anything. It pops up even when im not in an app. So it's more annoying than anything.

I'm using Xperia x10 mini. Whenever I try to add a contact to my phonebook, before clicking save this message appears: "The process android.process.acore has stopped unepectedly. Please try again." And I have no other choice but to click "force close"... Another thing is, even though my contacts' names appears in the messages in my inbox, when I click on the phonebook icon, the phonebook is empty...

Are the processes in android asynchronous? If they are asynchronous then how can we conclude when the activity or process is finished or completed its execution.

So since I got the phone on Thursday, at random, I'll get these popup crash messages, that say "The process com.google.process.gapps has stopped unexpectedly" it has a "Force Close" button, which doesn't seem to change anything other than to acknowlege the message.It will happen at random, sometimes while I'm on the home screen, or sending a text message, but more recently, as I was trying to manage & link contacts. When I searched for this message it seemed to be related to people using Gmail, but I always get this message when I'm doing other things and not even touching my Gmail account.

I've searched around the forums (here and SDX forums) and although it seems the few people that had this issue were able to solve it, my case seems a bit different.
It's different because of the people I've read solving the issue, it was a problem with something they changed / removed with gmail / gmail storage or talk / talk storage. And when they cleared the cache or re-installed the problem went away. Also, it seemed that the same people had a problem with downloading from the market...
Neither of the above apply to me, but yet I'm still getting this FC error all the time!
I was helping a friend with their CL14 Moment out of the box...and went from stock 1.5 CL14 to 2.1 DD03 w/Joey recovery to EclairDD10 and v5 root. I then did the streaming media fix, and then the private app (build.prop) fix (all previously done with my phone no problems). I did all of these update right in a row, and after my last re-boot the FC error (process com.google.process.gapps has stoped unexpectedly) started showing up and won't go away.
The only .apk / odex files I removed were the preloaded Sprint apps
Does anybody have any other ideas on how I can get this FC error to stop? I've tried clearing the cache / data for all the mail / talk apps, rebooted, cleared dalvik cache...

Is there a way to craft a daemon process as to make it "unlistable" to a process viewer?
OR
is there a way to dynamically change a process name?
I'd like to design a security application without having to modify the firmware, if possible (yes I know about "security through obscurity"...).

I am working on a simple application (studying purposes) which list all the files from a selected folder. On top of that I would like to have a search feature where the user can search for files (the code for that is already in place). Now, I was thinking about having the search running in the background somehow, whilst the user can still navigate, create folders, copy, sort and do other stuffs normally. When the search finishes the user would get a notification and then could click on it and go to that activity (It ideally should be the same ListView I already use for browsing the files, I would just need to update the Adapter there with the latest processed data after clicking in the notification). What's the best answer for that? Threading or AsyncTask?

Can anyone point me to a good example where a AsyncTask queries a local SQLite database and then updates the UI successfully. I have a database which I query using doInBackground... create a new custom SimpleCursorAdapter (overriding onViewBind), return the adapter (SimpleCursorAdapter), then in postExecute() create ListView adapter which is set to the the SimpleCursorAdapter, that was returned, then I set the listview adapter using SetAdapter(adapter);...
For some reason I throw an exception on fillWindow.java:200....

This part works fine.A button in the application make it possible to reload the data. I would like to run the AsyncTask but the sytem say i can't alter view in other thread. I have also read an AsyncTask can't be run another time So i would like to know what is the best way to do this and not to have the "application not responding" message.

I know this is not how an async task should behave but my question is how to "block" the user while executing it.My need is the following: I have my own backup/restore process and I have an async task to run these two actions. The backup is fine, I can warn the user when the backup is done and that's just fine But my problem is about the restore process. When the user click on restore he shouldn't be able to make any change in the application (and anyway don't want to because he would lose all his changes).I understand that having the user blocked while restoring (or maybe with a progress bar) is not a best pratice but I do not see any other possibility in this context.

I know how to use AsyncTask in a standard manner to manage operations that are in the background in relation to a UI thread.However,I want to run a task in the background which might run for a very long time under certain circumstances. In these cases, I would like to force the background task to fail if it runs for an excessive amount of time.I know that I can invoke the "get(long timeout, TimeUnit unit)" method of AsyncTask in my UI thread in order to terminate my background task if it runs too long. However, in that case, my UI will block while this "get()" command is waiting.There are probably other drawbacks to directly calling "get()" in this manner, not the least of which being an evil interaction with the "done()" method of AsyncTask's contained FutureTask object, which itself is calling "get()" at least this is what I see when I look at the source code for AsyncTask.

I have an activity that needs to do some stuff in the background. When the background is done, I want it to load a new activity.I can successfully kick off the async task and using using ViewSwitcher I can show a nice progress dialog.However, when the user hit 'back' or 'close' from the new task, I want them to see the main screen of this task again. So, I use the showPrevious() after I start the new Activity, but I see the screen switch from the loading window back to the main window BEFORE the new Acitivity is launched.How do I get it to switch after the new activity, or when they come back from the new activity?I tried onRestart() and onResume() but both of them seem to give me a view of -1 that I couldn't do much with.

I'm running a network service within an ASyncTask. I want to be able to time the task, and after a certain period of time interrupt it.Is there a simple way to do this? Basically, when the doInBackground() methods starts, I want to say "If it hasn't completed in 30 seconds, do something else".

I'm developing a game based on SurfaceView and a game thread for the whole game thing.Now I want to do some HTTP requests triggered on events inside the thread. They should of course be asynchronous, so the game doesn't stop. I found AsyncTask to be a neat way to do this but I'm having trouble implementing this at the moment. Maybe I misunderstood the concept of AsyncTask,I don't know it just drives me nuts as I read docs and blogs and still I don't get it. So sorry if that's a dumb question but I'm mad of thinking about it.

while debugging and app that uses AsyncTask to record audio and update UI I noticed that everytime that an AsyncTask object ends running (finishes doInBackground and onPostExecute or on Cancelled it´s thread stays alive (running status).At least for me that should not be the behavior of the class since the doInBackground task may not stay running forever (as an example the android manual says that a status bar should be updated by an asynctask, and it won´t last for the whole app running time).Is there anything I´m missing, as a method to destroy it, or should I just ignore and keep creating threads as I need and the VM will handle them as it needs resources?

Obviously AsyncTask IS a generic (http://developer.android.com/reference/android/os/AsyncTask.html#execute so why do i get those errors?

In order to get XML data from a server repeatedly, I'm attempting to use AsyncTask and Timer as per Mark Murphy's suggestion. I get the following error:01-07 16:11:26.705: ERROR/AndroidRuntime(729): Caused by: java.lang.Runtime Exception: Can't create handler inside thread that has not called Looper.prepare()I'm using SDK 1.5 with Eclipse on Windows.I've looked in documentation, on StackOverflow and in the Android Developers group, but I'm not clear what's causing the error or how to fix it.I can get the data once - i.e. without Async and Timer - and parse it via SAX without problems.s: I'm quite new to Android.

My program was going wonderfully. It is a search engine that connects to our back end database by sending Get requests to our server and displays the results. I've managed to get it to query my server and back end database, return results using JSON, return the first headers and pour them into a ListView widget in the main activity. Then when the user clicks on one of the headers it then sends another query from a sub-activity. It then parse those results and format them neatly into a WebView embedded into the sub-activity.
All this works perfectly. That is until I come to make a second query on the main activity. Listed below is my stack trace of where the error happens. I think I know why this is happening, but obviously not clearly understanding it.
I think it is because I am trying to call AsyncTask again. I remember reading that the AT can only be called once, but I presumed quite wrongly that this meant you can not do concurrent calls. I thought that once an AT had done it's task it was cleared and then could be called again, but this does not seem to be the case. Is it because of AT attempts at more than one call ? If so, would I be better changing that section into a Handler with a Runnable on the main activity?

I'm working out my first multi-threaded application using Android with the AsyncTask class. I'm trying to use it to fire off a Geocoder in a second thread, then update the UI with onPostExecute, but I keep running into an issue with the proper Context.
I kind of hobbled my way through using Contexts on the main thread, but I'm not exactly sure what the Context is or how to use it on background threads, and I haven't found any good examples on it.
Here is an excerpt of what I'm trying to do:
CODE:...........
It keeps failing at the sixth line there, because of the improper Context.
