I have a notification that starts my activity and passes a messages using the intent's putExtra() function. The message is then displayed to the user in the activity's onCreate function. When the application is restarted due to a orientation change, the message is shown again as it is still in the intent's bundled data.
How can I remove the extra data?
I tried the following:
Bundle bundle = getIntent().getExtras();
if (bundle.getBoolean("showMessage")) {
// ... show message that is in bundle.getString("message")
// remove message
bundle.remove("showMessage");
}
But the message will still be shown after the orientation changed, seems like the intent used is not the one I changed, but the original one. The only workaround I found is to save the showMessage additionally in onSaveInstanceState(). Is there another way? Or is this the way to go?
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?
On a click event I create a thread and start a long-running operation based on this method. After the long-running task is completed, it does a callback to another method, which does a post to the handler:
@Override
public void contentSearchModelChanged(Model_ContentSearch csm, ArrayList<Class_Reminder> newRemindersList) {
remindersList = newRemindersList;
mHandler.post(mUpdateDisplayRunnable);
}...........
This works beautifully when I do this normally. However, if I change the orientation while the long-running operation is running, it doesn't work. It does make the callback properly, and the remindersList does have items in it. But when it gets to this line:
r_adapter.notifyDataSetChanged();
Nothing happens. The odd thing is, if I do another submit and have it run the whole process again (without changing orientation), it actually updates the view twice, once for the previous submit and again for the next. So the view updates once with the results of the first submit, then again with the results of the second submit a second later. So the adapater DID get the data, it just isn't refreshing the view. I know this has something to do with the orientation change, but I can't for the life of me figure out why. can anyone suggest an alternative method of handling threads with orientation changes?
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 am writing an Android app, part of which will be a survey involving multiple pages of checkbox question and answers. I have created an activity to display the question and options (from the DB) and what I want to do now is when i press the "Next" button it should just reload the current activity with the next question set from the database. (the activity starts with survey.getNextQuestion() - so its just a case of refreshing the activity so it updates)

View 1 Replies View RelatedI am a very green android developer and need some help with a strange program crash. Often the program will run just fine. There is an equal chance it will fail (see stack at the end). I can watch the program run through the getView function and everything seems in order (i.e. all the information is there as expected and passes through convertView seemingly fine). Either it will go through a few times and then program will be A-OK or it will fail as seen below and I have not been able to pick out what causes the crash. Even stranger is that if I hold the phone in landscape mode, it will never fail!! It only fails about 50% of the time in portrait orientation.

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

View 2 Replies View RelatedI notice when using the emulator that when the screen is flipped, I get a following logcat message:
INFO/WindowManager(589): onOrientationChanged, rotation changed to 1
How can I catch this in the code? I want to know whenever the orientation changes. I assume I have to set a listener, but I can't find an example anywhere.
I'm doing an APP that shows some dialogs. Those dialogs are Alert dialogs, and when they are being showed if I change the orientation of the mobile I lost them...they are not being kept on the screen.

View 2 Replies View RelatedI am making an Android app which is currently coming along nicely - I've hit upon a couple of stumbling blocks.
1) How do I stop the screen from going dim/off and the phone locking while the application is running?
2) Can I force the phone to enter landscape mode on running my application?
My app *sometimes* when orientation change, leaks Activities (getInstanceCount() increases from time to time) and i cannot figure out where references to my Activity or rather Context are kept - tried to use jhat but it couldn't help me much.
what is strange: it doesn't always happen on orientation change, so its even harder to fix.
btw when doing normal app life cycle - start, do something, exit - everything is ok - getInstanceCount() always returns 1.
I have an activity that checks stuffs online when it's created (is the GPS on and if not it asks if the user wants to turn it on).
The problem I'm having is that it is also doing it everytime I change the orientation of the screen.
I've read some comments on onConfigurationChanged() but is there a better way to be sure I'm checking the GPS only when the activity is first created?
built a simple app that displays an alertDialog with two buttons.The problem is it's not getting dismissed when i change orientation. After change i get a leak warning on debugger and the dialog appears twice(pressing back hides the first dialog, only a second back dismisses it completely).

I am developing a photo frame widget, all works except on an orientation change to landscape mode my appwidget doesn't display correctly as I have it set to portrait dimensions and it is too large for the display. I would like to run some code to resize the image so that everything displays correctly and it uses all the space that I allot. What is the correct way to do this? I can think of 2 methods however both seem inefficient. The first would be to register a broadcast reciever to take orientation changes, however I don't want to redo my appwidget everytime the phone is turned on its side as the majority of the time the homescreen is not showing when the orientation is changed (ie other apps are used, and I don't need my code running in the background). I only need it to run when the home screen is shown. The second would be to setup a service to manage my appwidget but that also seems inefficient to be always running in the background.

View 3 Replies View RelatedWell, preventing an orientation change is easy. But what about doing it at run time.
Say, I have an activity which supports orientation change in normal situations. It has say three Edit Texts.
There's also a button, which when clicked would do some processing in a thread while showing a ProgressDialog which is not cancellable.
Ok, so till the user hits the Button, I want the activity to be able to adapt the orientation changes. I have two layouts files for each orientation with different layout schemes.
What I want is this. Once the user clicks on the button, and the ProgressDialog is showing, I don't want the activity now to be re- created again when the orientation changes. So, before showing the ProgressDialog, is there any way to tell the Activity not to handle Orientation change?
Also, once the process is complete, and the ProgressDialog is removed, I want the Activity again to be able to handle orientation changes.
In the following sequence of events:
1. Start a new thread (as a result of a button click - or similar).
2. User changes the screen orientation (causing the Activity that started the thread to be destroyed).
3. Thread finishes, and wants to do some dialog (or any UI) work. However, doing a showDialog, dismissDialog, ... will crash, as the thread it still referring to the old Activity.
This can be solved by updating the data in the thread to refer to the new Activity upon a screen orientation change.
However, couldn't the Android framework just forward any requests from a destroyed activity, to the newly created Activity, saving us developers of handling it ourselves?
