Android :: What's Best Way To Handle An Task Progress Dialog On Orientation Change?
May 27, 2009I have an app that communicates with a server.While it is communicating, it shows a progress dialog.The way this actually works is that I have a class that I call my Network Gateway.Each method takes a Handler as a callback so that the gateway can send back the response as a bundle when it has finished. Right now when someone changes orientation while a network operation is occuring, the activity doesn't know that a thread is running the network code and then the callback might be invalid.What's the right way to do this? I want to make it so that after the orientation switch, the activity can check something to see if a network operation is running and if so, display the progress dialog again and wait for the callback, or set itself as the callback handler now, invalidating the old one.My first guess is that this is exactly the kind of thing services were designed for, but I'd like specifics if anyone can supply them.

Jul 10, 2009My program does some network activity in a background thread. Before starting, it pops up a progress dialog. The dialog is dismissed on the handler.This all works fine, except when screen orientation changes while the dialog is up (and the background thread is going). At this point the app either crashes, or deadlocks, or gets into a weird stage where the app does not work at all until all the threads have been killed.How can I handle the screen orientation change gracefully?

Android : Progress Dialog Went Back To First View Called It When Dismiss
Nov 3, 2009I have a weird problem on progress dialog: I have 2 views: Login View and say, Display View. In Login View, when I click the 'Login' button, a progress dialog is created (new ProgressDialog(...)), shown and stored in a variable 'mProgressDialog'. After login, the dialog is dismissed and some information are displayed in Display View (Login View hides). Now I want to display another progress dialog when 'Update' button is clicked and when the update is done, dismiss the dialog and display new information. So I use: the Display View for a blink and then shows the Login View. I tried to change the view etc. but same problem happens over and over again. So I am thinking it might because one activity can only be assigned to ONE progress dialog and no matter how you re-create it you still get the same progress dialog. And the dialog is linked to a certain view which will be shown automatically when the dialog dismisses.

Aug 22, 2010I have an onKeyDown event which is only needed for handling the Up and Down hardware keys in my app. For these it returns true, as they are handled. For anything else it returns false which I understand means that the OS should handle them. However, when I press the Back button, my onKeyDown is called and returns false, but there is no other effect. I want/would expect the OS to finish the current Activity and resume the previous one.

Nov 6, 2009I have a simple edit control in my application and as expected the soft keypad comes up on tapping it. Now what I want to do is that when the user presses the back button, the activity should quit immediately without the soft keypad going down first. On handling the key event in my activity i found that the first 'Back' event is consumed by the keyboard and it does not even reach the activity. However once the soft keypad goes down, the events can be handled in my activity. Is there any way to override this behavior so that the back button first reaches my activity and I can quit immediately.

Android :: How To Repeat Login Dialog And Progress Dialog?
Jan 25, 2010I am having a problem about repeating Login dialog (an AlertDialog) and progress dialog, coordinating with http thread. I suppose repetitive Login dialog (if fail, continue) handling should be common and straightforward. I guess my approach must be wrong somewhere. I already spent 2 days on this and am desperate. So please help. User starts the app, the main activity starts.Show a login dialog (generated by the main thread, i.e. from on Create. The main thread then starts a wait_thread, which will wait for http to return data and check the data and decide what to do.After user input username/password and press login, a progress dialog starts.The progress dialog starts an http_thread to talk to the server and get replies. Once done, it will notify the waiting thread.If the user type in the right username password first time, the code works fine.But it always fail for 2nd time Login, i.e. When first login fail(wrong username/ password),the wait_thread will generate 2nd Login dialog to let user repeat the login process. But after user hit the login on this 2nd Login dialog, the system always crashes.

View 2 Replies View RelatedAndroid :: Progress Dialog With A Second Thread
Sep 26, 2009I've created ProgressDialog with a second thread according to the DevGuide,changes screen orientation or 2) hits the back button twice (first to hide the dialog, second to hide the app) to hide the application and run the app again after a while.Then, onCreate() is called (for the second time), and progress bar stops responding properly. My thread may work for a few minutes and I want to give the user possibility to hide it and do sth else. After a while he might want to run the app again in order to check the progress.I found a few articles concerning this topic, but I couldn't find the exact solution I should chose for this problem. So, could you tell mi what is the proper way to handle this? Should i save the handler and dialog state with "onRetainNonConfigurationInstance()"? If so, how to do it properly and is it safe?

Android :: Using Progress Dialog With Usertask
Aug 21, 2009I have an application that downloads some content from the network, processes it and displays it. When any link is clicked, the user task(async task) is used to download and process the content and the content is shown in the new activity.
I want to show a progress dialog until the content gets downloaded and processed. But when i call the progessdialog.show() method I am getting the following error.
'android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@435904d8 is not valid; is your activity running'
I use the get method to get the result from the user task. I make the main thread to wait until the usertask completes its work. I know this is a bad way, but the normal handler does not work here.I think it is not good idea to start a new activity in the onPostExecute method.

Android :: Showing A Progress Dialog
Jun 10, 2010I have looked at the Android API and other posts here on stackoverflow, but have not been able to figure this out.
My app downloads files to the sd card. I would like to pop a "loading..." dialog while the file is downloading and then have it disappear when the download is finished. This is what i came up with using the android API:
CODE:.............
However the dialog doesn't actually show. when i debug it, it claims that it is showing, but it is obviously not on the screen.
