So when the Progress Dialog appears and the user close the keyboard, the dialog dissappears and the application crashes. In the debugger i saw the exception "View not attached to window manager". May because the Dialog is not longer shown but the application want to remove it after the calculation? Here is the code where i start the dialog and the thread:Does somebody know how to solve this?
View 6 Replies View RelatedAs many of you know, back in October I had to make an emergency switch from Windows Mobile to Android. As you've all read in my posts, it has been a very "mixed" experience with both some impressive and downright pathetic discoveries, but one of the worst things about it (beside the complete inability to sync) is the way that Android closes your programs whenever it feels like it instead of letting you close them. Sometimes I'll be browsing the internet in Opera Mobile and I'll switch over to the email program briefly to check something, when I hold down the "home" key and pick OM from the list of recently used programs, it starts it all over again, and I know for a fact I didn't choose "exit".
Sometimes I'm glad Android "cleans up" (like if I back out of a program that has no "exit" option) because it saves me the trip to the task manager later, but is there any way I can prevent it from closing stuff I'm actually still using?
My problem is: Activity A called Activity B, and in Activity B, it start a background thread to do some client-server work. But it maybe takes too much time. So i add a cancel button to call the stop() method to stop the thread, and call finish() to finish the Activity B and go back to Activity A. Although it is back to Activity A, the thread isn't stop immediately. Can i just call the finish() to go back to Activity A, and leave the thread to exit by itself? If it is not the right way, which is?

I want to stop currently running thread but -Thread.stop() - Thread.destroy() are DEPRECATED so can any one tell me how to stop the Thread .
View 6 Replies View RelatedI am basing my game off of the Lunar Lander demo.
The problem I am having is my game not restoring its last saved state when it comes back into focus.
When the game loses focus/quits it saves all the information to a Bundle correctly, then runs surfaceDestroyed() to shut down the thread.
When I restart the game, I thought onCreate(Bundle savedInstanceState) method was supposed to always start first, then restore the saved Bundle if it is not "Null". But because it sees that I have started/ created a thread last time, it jumps straight to surfaceCreated method.
The only thing I can think of is to find a way to get rid/destroy the thread so that it runs onCreate at the start. However the stop() and destroy() methods for threads have been depreciated. Is there anyway to do this? Or is there a better method of saving an instance of the game? code...

View 4 Replies View RelatedMy application is basically a image viewer. It is opened from both camera and as a separate application.
I open the image viewer to view and edit the picture. Each edit operation is implemented using thread. If my application closes due to pressing the home button, the next time I open it with camera. It throws anr.
This doesn't always happen. Only when large edit operations or edit operations on large image files are done.
I get out of memory error, sometimes timeout.
I guess it s because the thread doesn't complete the edit operation when home is clicked. and it s still running on the background. so when i open it s unable to process it.
m I right?
If so what is the way to stop a thread before the completion?
I'm just wondering if anyone else is having this problem. When I try to open a Facebook contact, the people app keeps force closing and restarting.

I recently loaded Baked Snack 1.7 on my phone as my first custom ROM - before that I had rooted stock Froyo. I tried two Baked Snack kernels and now have KingsxKlick bfs #9.
So I have all these variables and now I have a weird problem - my address book is force-closing on me every time I try to create a new contact. I haven't created a new contact in awhile, so I have no idea whether this could be related to my new ROM or kernel, or if it's a problem with the address book itself. I have had no other problems since installing the ROM and kernel.
I can input the new number for the contact, but when I try to name the contact it says it has encountered an error and needs to stop. This is the stock HTC People app, and I have tried it creating the contact as a regular phone contact and as a Google contact. No dice.
I've also tried a battery pull, clearing cache, the basics.
Any thoughts, guys? I met a cute boy and I REALLY need to save his number.
What is most efficient way of keeping a check on time within a game thread? Currently I create a new Date() when the game starts and was thinking of creating another Date() within the game thread and comparing it with the first one. But with a screen refreshing at around 60fps (hence a new date object each time), I can't help thinking this is rather inefficient. What other ways are there of doing this?

Does anyone know a source or perhaps measured those numbers?
View 9 Replies View RelatedNeed help closing/accessing my views in a simple app (included an img of my program layout) but I might have been too confusing. Basically, I have an app that has a main menu where the user can click a button to open a camera. The user then snaps a photo and it is displayed on a page. The user will then click another button that detects faces. If faces are detected, the user is sent to a final page that shows the cropped face, etc. I give the user the ability to return to the main menu or snap a new photo.
Let's say a new photo is snapped and the user does it a few more times. Now I have multiple saved instances of old snapped photos (presented on the layout). How do I kill the previous instance (the layout from before he decided to snap a new photo)? So when I try to close the app it doesn't go back to the previous instance (displayed layout of said snapped photo). I am so confused on this one thing.
I am doing small project "Location Finder" in android.In that i have used different menu items,which include Close menu.On click of that menu i want to close the application.i have tried it with finish(),but it just the finish the current activity.

View 1 Replies View RelatedI have a service which runs in the background when the user starts using my app. I am using it to do some posts to our server. I always close my service by calling stopSelf as soon as the posts have been made or failed.
But I recently observed two times that my service did not stop. I saw that in the running services in settings on my device that it has been sitting there for over a few hours.
So I was trying to see if I can alternatively set a timer using which I can force the service to stop after a few minutes no matter what.
Recently, I have tried to know what would happen to an alive thread, when the device goes to sleep. I program a simple activity that will create and start a thread printing "HERE AM I" repeatedly through Log.d. I expect the thread would be stopped after I "echo standby > /sys/android_power/request_state." The screen is off, but the thread still keeps alive and prints out "HERE AM I." I don't know why the thread can't be stopped. I test this through emulator (1.5cupcake) and G1(1.1?), but the results are the same. Could anyone give me some suggestions or hints about this question?
