Android :: Progress Dialog And Orientation Changed
Jul 28, 2010
I'm facing some problems with the progress dialogs. I use a managed progress dialog to show the user that an operation is being carried out with the following code written in the onCreateDialog(int id) function.When the operation completes I call dismissDialog(PROGRESS_DIALOG). The problem is that if I rotate the phone while the progress dialog is displayed then when the operation completes the dismiss call has no effect and the progress remains showing. And this I cannot understand why.

I 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.

I download some data from internet in background thread (I use AsyncTask) and display a progress dialog while downlaoding. Orientation changes, Activity is restarted and then my AsyncTask is completed.I want to dismiss the progess dialog and start a new Activity. But calling dismissDialog sometimes throws an exception (probably because the Activity was destroyed and new Activity hasn't been started yet).What is the best way to handle this kind of problem (updating UI from background thread that works even if user changes orientation)? Did someone from Google provide some "official solution"?

My 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?

I 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.

I have created an activity for my game which handles all orientation changes by itself and has a fixed "portrait" layout. Actually it uses the accelerometer and is rendered using 2D canvas methods. If the level has been completed I show up a highscore dialog in which the user can enter his name. The dialog is floating above the underlying level screen which gets blurred out nicely. This generally works.
Problem is that the dialog does not get rotated if the orientation of the phone changes. So even if the keyboard is exposed the dialog is shown in portrait mode instead of landscape. I have tried to use an activity with dialog theme instead but the behavior didn't change. After several tries it seems that I have found the reason for this: Once there's an activity with fixed orientation in the activity stack then all subsequent activities keep this orientation, too. They will not react on orientation changes anymore (e.g. if the keyboard gets exposed).
After upgrading to 1.5 SDK the described behavior changed a little bit. Now at subactivities indead react on orientation changes like expected. However, the need to have an opaque background! That means that neither dialogs nor activities with dialog theme will work. Those will stick with the orientation of the underlaying activity. So my workaround is to first start a sub-activity with an opaque black background. This activity then shows my highscore dialog on top. It looks quite okay but I wonder if there's a better solution? Is it possible to show a dialog above a fixed portrait or landscape activity which automatically adapts to orientation changes?

I have a program with two layouts: - layout/main.xml - layout-land/main.xml
Also, i have some images en drawable and drawable-land...
My problem is: When i change the orientation of the emulator (for examplo: portrait to landscape) i don't know how reload the main.xml layout to update the screen with the new positions....
If I launch the emulator in portrait the application load the portrait layout, and if I launch the emulator in landscape mode the application load the landscape layout, but if I change the orientation in execution mode the application don't load the new layout...
How can I reload the layout?

My activity use the same RelativeLayout as it's content view whatever the orientation is. In this RelativeLayout, there is a FrameLayout align to it's bottom, and a TextView above this FrameLayout, just like :
CODE:...........
on android 1.5 device when orientation changed, the TextView lies in the wrong place, middle when portrait, bottom when landscape. on android 1.6 device It is ok.
How could I make it lies in the place where it should be on 1.5 device?

I snap a photo, and it gets placed onto an ImageView. When the user sees the page where the Image View is, and I turn the phone sideways where the orientation is horizontal, the app immediately returns to the app's main screen.

While working on orientation change I have found that the onConfigurationChanged is not getting called when changing the orientation from portrait to landscape.But when I am changing from landscape to portrait the method is getting called. Is it the correct behavior because the onConfigurationChanged should by called whenever we are changing the orientation. (android:configChanges="orientation")? I have also found one strange behavior or error, When we are changing from portrait to landscape orientation the string value is displayed correctly(automatically by android system) but when in am changing the orientation from landscape to portrait the same string is displayed(i.e the string in landscape mode).The expected behavior is the string id specified in the portrait mode should be displayed.Is it an platform bug or something wrong in my code/programming.

I am having a listview in my App which shows perfectly in Portrait mode. But when I change orientation to landscape, sometimes the width remains as that of Portrait mode. Even the scrollbar for the list comes at the center and remaining part of the screen remains blacked out. This happens only with the list view. Other views show perfectly. I have designed the layouts such that the Portrait layouts look feel proportionate in landscape mode. I want to avoid restarting the activity so I have not put the layouts in the landscape folder. I tried invalidating the listview in onConfigurationChanged() but of no use. When I navigate in the list in landscape mode, the width automatically gets adjusted.

I got my hands on Android which is really fun. But at some point I don't seem to understand the concept. I've got a Main class which reads like this:
CODE:....
In the onCreate(...) I set the layout to setContentView(R.layout.main); and add an OnTouchEvent Listener to the sole View in main.xml: myView.setOnTouchListener(new OnTouchListener() {@Override public boolean onTouch(View v, MotionEvent event){...
As you can see I also implemented a SensorEventListener which is used if required. All works fine so far.
But my problem is this (at this point my misunderstanding kicks in): whenever I rotate the device the onCreate(), onStart() etc. methods are called, causing my app to act as if it just started. Furthermore, I feel unable to implement an onSizeChanged(int w, int h, int oldw, int oldh) { ... } Listener.
Can anyone please explain where my error in reasoning is? I am working on a tiny app which is more or less done, except for the just mentioned bug(s). Maybe I got it all wrong but it does what it is supposed to do (i.e. sending touch positions and accelerometer data over the network via UDP).

I'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?

I 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.

I 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.
