I use sdk 1.5 version and same to my handphone, my handphone is use G1. Now i test my application on my handphone. When i push on keyboard, i found system will destroy current activity(execute onDestroy() method) and execute onCreate() method again. So i will all current status and all datas. I don't wish this happen, how to block system execute onDestroy() and onCreate() when i open and close keyboard?
View 2 Replies View RelatedMaybe my question might seem a bit weird, but I have an activity in which, in one case , I have to move to another activity before it finishes loading the screen. My condition is in the onCreate method, which means when I encounter it, i get a "startActivity called from outside an activity context" error and the app just crashes. But then, is there an easy way like a flag for the intent to make it work without having the activity context resolved?

Here are it's method:
CODE:..................
My question is, why is onCreate acting like it's in a while loop? I can click on the button whenever, and it makes the sound. I might think it was just a property of listeners, but the Button object wasn't a member variable. I thought that Android would just go through onCreate onse, and proceed onto the next lifecycle method. Also, I know that my current way of seeing if the sound is playing is crap...I'll get to that later.
I call an activity from another with startActivity(new Intent(Caller.this, NewActivity.class));
I had a problem with a variable. So, using debug I saw that I pass two times in the onCreate method of NewActivity!
I was a little bit surprised. Somebody can explain why and how can I avoid this behaviour?
I am encountering an exception in the onCreate method of an activity.

I've already changed the ID of the ExpandableListView to "list". But it is not effective.
I have some code in the onCreate method an Activity and noticed that it is being called three times. Is it normal behaviour?
View 1 Replies View RelatedIn my android app I call the voice recognition in my onCreate method of my startup activity. I have made it a preference to start up with the voice control or not. However, the app takes about 5-7 seconds to load when voice recognition is on. When it is off, the app starts almost instantly. Below is sample code, I have added Free_Form, max_results 1, and a custom prompt to mine.Why would calling the normal android speech recognition take sooo long to load in my OnCreate method?

Sometimes it does not do it on it's own and I'm having to view things while the keyboard is there. If I hit the "back" button on the bottom of the EVO, it takes me to the previous page and if I hold the "menu" button down it pulls up the browser's menu. What am I doing wrong if anything?

In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition. If I try hitting F3, I get a "The Jar of this class file belongs to container "Android 1.6" How do I show the definition of the method I am using when there is a warning?

View 4 Replies View RelatedMy prob is the following: My android application has the class TestActivity (entrypoint) -my app uses "library.jar" wich contains J2ME classes, used as library -library.jar also includes "UIActivity" [can spawn several dialogs] wich is called by a (j2me) class of library.jar -I only have the .class files of the j2me-lib stuff, so I cant modify them, but I can do so on Android-classes
so... the short form:

finally I get the error:

Do I have to use Services instead of Activities? But afaik I have to give a reference of an activity to spawn dialogs.
Leaving aside the lamentable wording of the documentation for this method, it's not really acting as I hoped for an ImageView. I call toggle() from the onClick method of the view but the view system does not redraw my drawable with the checked state. However, if I initialize CHECKED_STATE_SET with android.R.attr.state_checked then the view is draw with the checked state.
So apparently my call to setImageState is not updating the state of the ImageView. The documentation for setImageState is totally blank in the case of an ImageView. What does this mean?

For those of you that are familiar with better keyboard. I was wondering about an easy way to switch from the t9 keyboard to the regular qwerty keyboard. I was under the impression that swiping left would toggle between the 2 but all that does is bring me to the numbers and symbols keyboard. I've been changing back and forth to the android keyboard because its faster than going into the better keyboard settings.
View 13 Replies View RelatedI have been looking it up and I just cant seem to wrap myself around the onCreate and Bundles. I understand that the onCreate is called when the program starts but its how the Bundles get passed around and how they are pertinent. Can anyone try to put this into plain english because I cant seem to find it well described.
View 1 Replies View RelatedI 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?
I try to call inside onCreate() it is ok but not onClick(). How to make it work?
View 3 Replies View RelatedI'm having a hard time resolving a crash report. It's an OutOfMemory exception that occurs during the setContentView in the onCreate of my main activity.
I just want to be sure I understood Android LifeCycle well :
1) The onCreate of my main activity is called once and only once during the life time of my application ? Is that correct ?
2) Just like for the big bang, before the oncreate of my activity, nothing exists for that activity, so memory consumption is zero, no objects exists right ?
So what can cause that sometimes, with random framework and devices, I get an OOM exception ? I mean if say my background image is causing this, it should blow up everytime, on every device, shouldn't it ? I mean the result should be reliable.
The background image is a standard jpg : 360*480 weighing 37kb, nothing fancy really :s

I'm opening an Activity using this:
startActivity(new Intent(Parent.this, Child.class)); And on the child, I have this code on the onCreate function (the if contains more than just true, of course): public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState); if (true) { AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setPositiveButton("OK", null); builder.setTitle("Error"); builder.setMessage("Connection error, please try later.") .show(); finishActivity(0); return;}}
Why is the activity not closing? I get the alert box, but then I have to tap the "back" button to go back.

Phone was an HTC My Touch. I got the prompt to choose what activity, browser or youtube, chose youtube.
I understand that Android Activities have specific lifecycles and that onCreate should be overridden and used for initialization, but what exactly happens in the constructor? Are there any cases when you could/should override the Activity constructor as well, or should you never touch it?
I'm assuming that the constructor should never be used because references to Activities aren't cleaned up entirely (thus hampering the garbage collector) and that onDestroy is there for that purpose. Is this correct?

I got this class, and nothing inside the onCreate is happening? Does it not automatically get called upon initialization?
Code is below.

Doing this results in a "application has stopped unexpectedly. Please try again". If I initialize the string to some set of characters instead of null, it'll just stay that way. Should it not do what is inside the onCreate() and make that change?
I know that network activity and expensive operations should not be done on the ui thread, but what about database activity?
I have an activity that, when started, I query an sqlite database and dynamically populate rows in a tablelayout with an inflator. I do this all in the oncreate() method. Should this be done in a separate thread?
What is the lifetime of a ContentProvider in Android? After onCreate() is invoked, will the ContentProvider persist unconditionally for the lifetime of the process?
My ContentProvider manages a list of records, but only 1 is designated "active" and will be accessed by different applications a lot. I was wondering if it's safe to cache the index of this active record in memory as a member of my ContentProvider to speed up lookup.
Why if I start the MPlayer from the onCreate it doesn't start?
I tried also from onStart(), but the only working way was from onTouch or on key press.
Any idea how to start it without any additional user input needed?
