[android-beginners] Re: need clarification on resolving intents.
ok, thanks! I see that for action VIEW, the type fields are different.
But in general, back to my question
What if an intent matches two or more activities - how is it resolved?
Since Android is meant to be very loosely coupled, it is likely that
activities from different applications may match the same intent.
Traditional systems are more tightly coupled.

The MIME type is only one of the criteria used for determining if an
Intent matches an IntentFilter.
Another is the action. In the cited example, NotesList responds to
android.intent.action.GET_CONTENT for
vnd.android.cursor.item/vnd.google.note, while NoteEditor responds to
android.intent.action.VIEW and android.intent.action.EDIT for
vnd.android.cursor.item/vnd.google.note.
So, if a VIEW intent for a note comes in, it will match NoteEditor
(match on action and type) and not NotesList (match on type but not action).

[android-beginners] need clarification on resolving intents.
What if an intent matches two or more activities - how is it resolved?
In the example provided on the intents page,
http://code.google.com/android/reference/android/content/Intent.html
both Noteslist and NoteEditor have type
So in the example, an intent like
{ action=android.app.action.VIEW data=content://
com.google.provider.NotePad/notes }
How can we be sure it will map to the the NotesList activity and not
to the NoteEditor?

[android-beginners] Re: Understanding the basic overridden onCreate function
OK, I see. So basically, by calling super.onCreate
(savedInstanceState) one is making sure that any code in the
superclass gets run, and then the stuff that is custom to the new
class.
Thanks.

The entire application does not restart, but the activity is indeed destroyed and recreated. This happens so that you can use alternative resources (using, for instance, res/layout-land or res/drawable-land) in your application. It is the correct, default behavior for all apps and certainly not an issue. Most system apps (like the Home screen, Alarm Clock or Calculator) work that way. Unless your app really is not meant for landscape mode (which could be the case for a game for instance), I would really advise you to NOT work around this. A cool thing about Android is that most apps work in both orientation and apps that don't support orientation change can be surprising or even frustrating to the user. -- Romain Guy www.curious-creature.org --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

The pseudo-variable super represents the superclass. By calling
super.onCreate(savedInstanceState), you are "chaining to the
superclass", calling its constructor before performing the guts of yours.

[android-beginners] Understanding the basic overridden onCreate function
I'm trying to understand the code for the basic onCreate function that
is part of every application.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
I understand the @Override, and the function declaration. It's the
second line that I am confused about:
super.onCreate(savedInstanceState);
First of all, what is super? Secondly, why is it necessary to call
another onCreate inside of the overridden onCreate function. Can
someone explain to me what is happening here? Thanks!

I just now tested RotationFour on a G1, and the behavior matches my emulator -- the screen stays portrait regardless of the position of the keyboard. So, some questions: 1. Do you have a G1? If so, what happens when you run RotationFour on your G1? 2. Which version of the SDK are you on?

Unzip the archive, and build and install the Rotation/RotationFour project. I just tested it, and whether the emulator starts in portrait or landscape, or switches to landscape, the activity stays in portrait mode.

[android-beginners] Re: ListActivity with image and text
I want to load images into my list view from the web. I have a URLs of the images/thumbnails which I've retrieved from an rss feed and stored in a table. Is this possible with a list or cursor adapter or is there another way? What is a good way to prepare loading and display of a set of images? In some cases I just want to display images in the list, in other cases I might have an mrss file defining a slide show and I would want to show them in a grid, list or gallery/switcher view. creating the view is no problem. The part I haven't seen any examples of is resolving the url to something usuable like content uri or displayable... I can load a single image into an ImageView by creating an InputStream from the URL, but is there a better way when dealing with many remote images? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

Steve, I'm sure the instance is created by

so the constructor will have been run by the time we do

At what point does the surfaceCreated() method fire? I presume its

[android-beginners] Re: Assistance with understanding LunarLander code
Hi Richard,
OK, so it looks like the line:
mLunarView = (LunarView) findViewById(R.id.lunar)
creates an instance of the LunarView object, running the constructor.
I didnt think that running the findViewById and casting to a LunarView
would have this effect.
Thanks for that

[android-beginners] I broke my project
Im not sure what i did but now every line of code that specifies a resource in the res folder is underlined in red. I tried to manually add the raw directory under res and ithe compiler could not resolve any of the items in the raw folder. i took one of eclipses suggestions to fix the problem(can't remember which option i chose) and then everything broke. Any suggestions? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
