You can create a custom preference, perhaps subclassing an existing

[android-developers] Using contacts

2010-07-05 Thread Lieuwe

I have an issue regarding the use of contacts in my Android
application. I currently do the following:

Intent intent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);


which allows me to pick a contact. 2 Questions:

- How do I limit this to only contacts with a mobile number
- Why does the intent not honour the way I have set up my contacts on
the phone itself? I have set up the contacts so it will not use gmail
and facebook ones, just phone ones however using the Intent I see them
all

In my experience, when a user has left a negative comment AND emailed

updated their original comment to be positive. Ok, you could argue
that the fact they have followed up their comment with an email means
they are different from those Doesn't work. Uninstalled users, but
still I think it would result in a significant number of comment

  login form is supposed to appear, I hide the other views and show the
  login form controls and I handle the events in the main activity class

  2. show a popup window that coves 90% of the screen and have it load a

  goes above a text control and one cannot see what he/she types.

  So, what other options are there for the implementation of a screen

Re: [android-developers] Re: Deploy App on Google Android G1 Phone

2010-07-05 Thread Lamia Hannoun

Actually i use the IP used by the LAN to identify my machine. Still have the
same issue


2010/7/5 Indicator Veritatis mej1...@yahoo.com

 Real IP? Which one? The one used by the LAN for identifying your
 machine, or the one NAT translates it to for the outside world to see
 the same machine?

 10.0.2.2 is in the block reserved for the former, i.e., it is for
 internal use only: if you are trying to access it from the WiFi on
 your phone, also inside the LAN, that should work fine, unless your
 firewall is on super-paranoid settings; but if you are trying to
 access it over GSM/GPRS/Edge, you need the latter, a public address,
 AND you need to sure your server is accessible from outside your NAT
 and firewall.

 Can you access your server from another machine outside your LAN? I
 assume you can access it from inside, but thanks to NAT, you should
 not expect that to work with the same IP address: it is common not to
 be able to see external addresses from inside.


 http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch01_:_Why_Host_Your_Own_Site%3F#Our_Network
 goes into considerable detail, including references, on all the issues
 surrounding the basic problem you are trying to solve: providing your
 own webserver in your small home/office net (LAN), and making it
 publicly accessible.

With the WRITE_EXTERNAL_STORAGE permission, you can write to the SD card.

most of article is asked about SD card written. Is there no way to
save data internal side?

You can call getFilesDir() from your Activity or Service to get a
directory in the on-board flash that you can read and write to.

So when i install the application to real device. then its application
installed in SD card or internal space?

For Android 2.1 and earlier, it is installed in internal space.

For Android 2.2 and beyond, you have the option of allowing the user
to install it on the SD card or internal space.

So, how do we write the file to SD card and specified the absolute
path where we saved? to load this file.

Use Java file I/O. Use Environment.getExternalStorageDirectory() to
get a File object pointing to the root of the SD card.

[android-developers] ProximityAlert Exists

2010-07-05 Thread Prasanna Perera

Hello,

Is there a way to find out whether a proximityAlert exists?

I am allowing the user to add proximityAlerts to be activated sometime
in the future based on alarms.  However, the user can change her mind
and remove a proximityAlert.  Before removing a proximityAlert I need
to find out whether the corresponding alarm has gone off and whether
the proximityAlert exists.  How do I know if a proximityAlert exists?

Thanks,
Prasanna

[android-developers] Accurate sleep()\timer in Android

2010-07-05 Thread Omer Gilad

Hello,
Does anyone know of a precise way of measuring 80 milliseconds for
scheduling purposes?
Thread.sleep() and SystemClock.sleep() don't seem accurate enough.

Purpose - I want to schedule a certain event to happen in an exact
interval of 80 milliseconds and I don't want the time to skew
(scheduling 1000 such events must take 80 seconds in total).

Thanks

[android-developers] intent to launch flash swf files

2010-07-05 Thread siliconeagle

Hi,

I am working on a podcasat player and am looking for a sutable intent
to launch and play a downloaded SWF file. I am on 2.2 and have adobe
flash player installed.

The things i have tried are:
This launces the HTC flash player to select a file:

ComponentName toLaunch = new
ComponentName(com.htc.flash,com.htc.flash.FlashPlayer);
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_MAIN);
intent.setComponent(toLaunch);
act.startActivity(intent);

This should launch the file in the htc flash player - but it doesnt
seem to work. the file never plays (I know the file works)
File localFile = new File(/sdcard/test.swf);
url = Uri.fromFile(localFile).toString();
ComponentName toLaunch = new
ComponentName(com.htc.flash,com.htc.flash.FlashPlayer);
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(url), flash/*);
intent.putExtra(play, file.path);
intent.setComponent(toLaunch);
act.startActivity(intent);

i put the file on the network server and i get this line in the log
file, the file plays ok in the browser:
action=android.intent.action.SEARCH;launchFlags=0x1000;component=com.android.browser/.BrowserActivity;S.query=192.168.1.2%2Ftst.swf;S.user_query=192.168.1.2%2Ftst.swf;end

So I am wondering if i can just launch the browser to get it to play -
i haven't had any luck yet.
File localFile = new File(/sdcard/test.swf);
url = Uri.fromFile(localFile).toString();
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_SEARCH);
toLaunch = new
ComponentName(com.android.browser,com.android.browser.BrowserActivity);
intent.setData(Uri.parse(url));
intent.setComponent(toLaunch);
act.startActivity(intent);

And i have tried the obvious:
File localFile = new File(/sdcard/test.swf);
url = Uri.fromFile(localFile).toString();
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
act.startActivity(intent);

Has anyone done it before?

Re: [android-developers] Re: How to force App Widget in portrait mode???


Gulfam,

This is kind of non-obvious to get right, although really pretty simple.

When home screen orientation is changed (is this a Moto Droid / 
Milestone, by any chance?) Android uses the most recent RemoveViews 
object to recreate widgets, since there is no onCreate() equivalent.


If the most recent update for your widget only specified a text or image 
change, and didn't include PendingIntents for clicks, then the widget 
will stop responding to clicks, or misbehave in other ways.


The trick is that each and every RemoteViews has to specify complete 
widget state - including all the PendingIntents, text item and image 
item changes, etc...

 Hi guys,

 I am using the default photo picker (usually Gallery or CoolIris
 Gallery3D) to pick an image from my application. The problem is that,
 when using Gallery3D, the user always needs to choose the album (aka
 bucket) and then the image, while it would be more intuitive to open
 directly the album the user was navigating on previously.

 For instance, let's say the user is working on an image stored into
 the sdcard. When she decides to choose another image, it is probable
 that she wants another image from the sdcard. So my question is: is
 there a way to tell CoolIris Gallery3D to open on a specific bucket? I
 have taken a look at the source code and couldn't find any.

 Testing on the emulator with Android 2.2 Google APIs. Here is the
 skeleton of my test application:

 public class GalleryTest extends Activity implements OnClickListener {
    private static final int PICK_REQUEST_CODE = 0;

   �...@override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.main);
        this.findViewById(R.id.pickbutton).setOnClickListener(this);
    }

    public void onClick(View v) {
        this.startActivityForResult(createIntent(), PICK_REQUEST_CODE);
    }

   �...@override
    public void onActivityResult(int requestCode, int resultCode,
            Intent intent) {
        if ((resultCode == Activity.RESULT_OK)
                 (requestCode == PICK_REQUEST_CODE)) {
            Uri imageUri = intent.getData();

            if (imageUri != null) {
                ((TextView) this.findViewById(R.id.photoname)).setText(
                        imageUri.toString());
            }
        }
    }

    private static Intent createIntent() {
        Intent intent = new Intent(Intent.ACTION_PICK);

        intent.setType(image/*);
        return intent;
    }
 }

 Sure it's easy - and also a major waste of limit screen space for a one-time

 I get your point about some people not realizing functionality is there, but
 again, it's a one-time learning experience that really doesn't justify a
 dedicated button or whatever, IMO.

 The skipping entries in the ADC2 app, for example, was just poorly
 implemented - that should have been a dedicated button with the frequency in
 which it was going to be used.

 Use a quick start dialog on the user's first run to let them know this
 exists, or Toast messages as Tips as they navigate the screens perhaps.


Even with a Toast tip, the user must still remember whether or not the
menu exists, which indeed is a trivial task for a single activity but
not so trivial when there are a hundred activities.  If the
presentation of icons that don't do anything is trivially handled by
one time learning experiences, perhaps the application launcher should
not bother to remove the icons of deleted applications. :*)

 You shouldn't pass an instance of that class toonSaveInstanceState().
 Your data model is not part of your instance state.

 If you are trying to deal with orientation changes, return your
 RestaurantList in onRetainNonConfigurationInstance() and get it back
 in onCreate() via getLastNonConfigurationInstance().

 Otherwise (or perhaps even if orientation is your issue), move that
 data out of the activity into a database, or in a pinch a Java object
 mediated by a service (so it will stick around despite activities
 coming and going).

[android-developers] Question about parcelable object

2010-07-05 Thread jul

Hi,

I want to save a list of Parcelable Restaurant objects on
onSaveInstanceState. I created a Restaurant class extending Parcelable
and a RestaurantList object, both shown below. In my main activity I
fill my RestauranList directly from json internet data using GSON:

restaurantList = gson.fromJson(r, RestaurantList.class);

Now, when I want to save the List of Restaurant objects using

protected void onSaveInstanceState(Bundle outState) {

if (restaurantList != null ) {
outState.putParcelableArrayList(restoList,
(ArrayListRestaurant)restaurantList.getRestaurants());
   }

super.onSaveInstanceState(outState);
}

I get an error, I guess because Parcelable data are not written. How
should I do it? Do I have to create an array of Parcel objects in my
main activity and fill it by calling writeToParcel for each of the
Restaurant objects?

thanks for any suggestion

Julien

Re: [android-developers] Question about parcelable object


Jul,

Parcelable implementation looks good, except for the questionable cast 
to ArrayListRestaurant, but that shouldn't have any effect.


What error are you getting, exactly?

Hi,

I want to save a list of Parcelable Restaurant objects on
onSaveInstanceState. I created a Restaurant class extending Parcelable
and a RestaurantList object, both shown below. In my main activity I
fill my RestauranList directly from json internet data using GSON:

 restaurantList = gson.fromJson(r, RestaurantList.class);

Now, when I want to save the List of Restaurant objects using

 protected void onSaveInstanceState(Bundle outState) {

 if (restaurantList != null ) {
 outState.putParcelableArrayList(restoList,
(ArrayListRestaurant)restaurantList.getRestaurants());
}

 super.onSaveInstanceState(outState);
 }

I get an error, I guess because Parcelable data are not written. How
should I do it? Do I have to create an array of Parcel objects in my
main activity and fill it by calling writeToParcel for each of the
Restaurant objects?

thanks for any suggestion

Julien

[android-developers] ViewSwitcher with AsyncTask

2010-07-05 Thread elubin

I have an activity that needs to do some stuff in the background.
When the background is done, I want it to load a new activity.  I can
successfully kick off the async task and using using ViewSwitcher I
can show a nice progress dialog.  However, when the user hit 'back' or
'close' from the new task, I want them to see the main screen of this
task again.  So, I use the showPrevious() after I start the new
Activity, but I see the screen switch from the loading window back to
the main window BEFORE the new Acitivity is launched.  How do I get it
to switch after the new activity, or when they come back from the new
activity?  I tried onRestart() and onResume() but both of them seem to
give me a view of -1 that I couldn't do much with.



public class XXXActivity extends Activity implements OnClickListener {
private ViewSwitcher views = null;

@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
views = new ViewSwitcher(this);
View homeView = View.inflate(this, R.layout.home, null);
views.addView(homeView);
views.addView(View.inflate(this, R.layout.loading, null));
setContentView(views);
final Button xButton = (Button)
homeView.findViewById(R.id.button_x);
xButton.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch(v.getId()) {
case R.id.button_x:
MyAsyncTask mTask = new MyAsyncTask(this);
views.showNext();
mTask.execute();
break;
}
}
private class MyAsyncTask extends AsyncTaskString, Integer, Boolean
{
  XXXActivity parent;
public CheckScannedCouponTask( XXXActivity x ) {
parent = x;
}
@SuppressWarnings(unchecked)
@Override
protected Boolean doInBackground(String... params) {
  // do lots of background stuff here
return true;
}
@Override
protected void onProgressUpdate(Integer... progress) {
  // update some progress here
}
@Override
protected void onPostExecute(Boolean b) {
Intent intent = new Intent(parent, 
AnotherActivity.class);
parent.startActivity(intent);
parent.views.showPrevious();
}
}
}

[android-developers] Emoji Support

2010-07-05 Thread fr4gus

Hi all,

Does anybody know about Emoji support for Android?

http://en.wikipedia.org/wiki/Emoji

We are going to port an iPhone application to Android, and this
application supports emojicons. For iPhone, the user needs to
install a keyboard app in order to be able to send emojicons, but
even without this keyboard, an iPhone is able to display emoji.

Cheers

[android-developers] Layout Params classcastexception

Hi all.

I have a ListView created programmatically and each view is a
TableLayout.

I am trying to get the Tables to expand to 100% of the list view, but
it does not matter what type of layout params I set on the TableLayout
I get a ClassCastException every time. Ie, I've tried
TableLayout.LayoutParams, LinearLayout.LayoutParams,
FrameLayout.LayoutParams, etc, all of them.

Any advice on what I'm doing wrong ?

Treat it as an object temporarily. Use your debugger or

[android-developers] Re: Layout Params classcastexception

I stepped through the debugger anyway. The type is TableLayout
$LayoutParams as expected and as soon as I pass this into the
setLayoutParams call it explodes.
This happens regardless of whatever type of LayoutParams I use - and
I've tried them all.

I am trying to get the yellow background to stretch the entire row (I

If you run this you will get a ClassCast

LinearLayout layout = new LinearLayout(this);

ListView list = new ListView(this);
list.setBackgroundColor(Color.GREEN);
list.setAdapter(new TestAdaptor(new String[] { kronenburg, 
san
miguel, sam adams }));

layout.addView(list);

setContentView(layout);

}
}

class TestAdaptor extends BaseAdapter {

private final String[]  strings;

public TestAdaptor(String[] strings) {
this.strings = strings;
}

public int getCount() {
return strings.length;
}

public Object getItem(int position) {
return strings[position];
}

public long getItemId(int position) {
return position;
}

public View getView(int position, View convertView, ViewGroup parent)
{

TableLayout table = new TableLayout(parent.getContext());
table.setBackgroundColor(Color.RED);
table.setLayoutParams(new
TableLayout.LayoutParams(android.view.ViewGroup.LayoutParams.FILL_PARENT,

android.view.ViewGroup.LayoutParams.WRAP_CONTENT));

TableRow row = new TableRow(parent.getContext());
row.setBackgroundColor(Color.YELLOW);
table.addView(row);

TextView textView = new TextView(parent.getContext());
textView.setText((String) getItem(position));
row.addView(textView);

return table;
}
}

[android-developers] Re: Best practice to pass persistent objects from an activity to another activity

2010-07-05 Thread Indicator Veritatis

Why not put it in SharedPreferences? True, you will have to do the
serialization by hand, since Android's support for it is so limited
(java.io.Serializable for pure Java classes only), but unless you have
a complicated object, that should pose no problem (if you do have a
complex object, consider XML with JSON instead of binary
serialization).

When I say serialization by hand, what I mean is that you must break
the object down into String, Int, Float and Boolean yourself, so that
you can use SharedPreferences.getBoolean() etc.

http://developer.android.com/guide/topics/data/data-storage.html#pref
has sample code for this, as well as a discussion of other options.
But this option is most likely good enough.

It depends very much on the object you want to pass and how its going to be
used. I've used a number of different techniques in my applications, and
each one is best suited to different situations.

 I'm trying to design an app that not only functions well, but looks
better than everything else out there was the excuse for ignoring the

 I really do take what you say to heart.  I would love to abandon fixed

 I'm trying to design an app that not only functions well, but looks

 easier to create stunning looking graphics for the iPhone because you
 know exactly the spec to design your graphics for.  I want to create
 apps that have a polished, high end look to them for Android.  For me,
 that means rendering my interface in a 3d graphics environment (even
 if the end result is just a 2d display).  I would attach a screen
 shot, but I don't know how in this forum.

 I realize I am fighting the way the platform is intended to be used.
 My scenario is that I'm writing a utility that has graphics that cover
 a 320x480 display and a 480x720 display using a surfaceview.  I have a
 layout under the surfaceview that positions buttons based on the size
 and density of the display.  My graphic has drawn buttons and needs to
 overlay the actual buttons from the layout.  That is the reason why
 I'm struggling with resolutions and densities.

 I've taken your advice and wrote a new routine to manually load the
 images I need based on the screen size of the device.  I've actually
 made it a generalized routine, so adding support for future unknown
 displays will be trivial.

 Thanks again for all your hard work and taking time out on this
 holiday to help me out.  Hopefully I have a chance to meet with you at
 a future I/O conference.

  So I strongly recommend not going down this route, and instead using another

  stick all of your possible graphics in drawable-nodpi, and at run time look
  at the space you have on the screen and other information to determine
  exactly which graphic you want to use for that environment.

  Definitely don't do things like try to mix physical screen resources, with
  density resources, with screen size resources.  It IS well defined which
  resource you will end up with given a particular screen (via the resource

  exactly what you want.  If one were to ask is a large screen resource
  better than a high density resource? well...  it depends.  For our purposes
  we will always match screen size before density since layouts tends to be
  more fragile than densities (we can after all always scale graphics), but
  you are going against how the platform thinks about screen sizes so you
  can't really count on it doing what you want here.  That is, screen size
  and density are two completely orthogonal things, and have no bearing on
  each other.  You are trying to put them together, and fighting with the
  platform by doing so.

  And honestly -- just DO NOT use absolute screen size configurations.  Those
  are deprecated for a reason.  They will only cause pain.  They just do not
  work for being able to adjust for the kinds of different screens we have.

  But let me say one more time: with the approach you are taking, there is a
  good chance you are going to end up having to tweak your app each time a
  device with a new kind of screen appears.  It is going to cause you some

Re: [android-developers] Re: Avoid non-static inner classes in an activity?

2010-07-05 Thread Dianne Hackborn

The getApplicationContext() should return return the same Application object
as getApplication()...  however, they do go through slightly different
code-paths (the Activity has its Application handed to it during
initialization, while the base Context implementation needs to retrieve it
for its package), so there could have been differences in behavior at times.
 We should probably have a CTS test for this.

The main limitation of using an Application context is that it can not do
direct UI.  Activity represents the application's direct interaction with
the user, so knows how to associate a Dialog or other UI element you make
with the correct Z ordering in the window manager.  The Application object
in contrast lives separate from the app's UI flow, so can't properly display
its own UI.  That said, you can use it to display a toast (which briefly
overlays on top of all UI) and of course a notification.

Also the resources you get from Application should be as fine as those from
Activity.  The main thing to watch out for (and this also applies to
Activity) is that if a configuration change happens while the application
doesn't have an activity displayed, then the resources won't be updated.
 They will only be updated when the user next returns to the app.  This is
done so that if you for example rotate while in one app, we don't have to
rebuild the resources in every other app when you return to it even if by
that point the orientation is back to its previous state.

 If the Application is really the context you want, then
 getApplication() will get the right one.  But the other problem is
 that people often are confused about what context they want, and
 usually the Activity is it. So a much more common source of bugs than
 using the wrong way to get to the Application context is using the

Re: [android-developers] Accurate sleep()\timer in Android

2010-07-05 Thread Dianne Hackborn

You are doomed if you just want to be able to schedule exactly 80ms every
time so that you add it all up after 1000 times and you get 80 seconds.

At the very least, you should schedule your events so that even if there is
some jitter in individual timings they add up correctly -- that is start at
the current time, then schedule each next event for a successive 80ms from
that base time, regardless of when the previous event actually fired.

At this point, then, the only question is how much jitter between events you
will find acceptable.  As Richard said, some big events can cause a fair
amount of jitter, in particular GCs.  The platform is designed to avoid
thrashing through objects and thus not cause GCs, so if you are likewise
careful you may be able to do things so that GCs don't happen enough to be
an issue.  For perspective: on low-end hardware, a GC can take on the order
of 100ms; on higher-end devices like the Droid it is more like 30ms.

If that is still not sufficient, you may want to consider dropping down to
native code and doing the timing in a separate native thread (which thus
won't be paused by GCs).  Of course you still won't have 100% accurate 80ms
every time because there will still be other processes wanting to run at
times, though the jitter will be significantly smaller (as long as your
process is not in the background scheduling group).

On Mon, Jul 5, 2010 at 7:30 AM, Omer Gilad omer.gi...@gmail.com wrote:

 Hello,
 Does anyone know of a precise way of measuring 80 milliseconds for

[android-developers] Re: Speech to text not working behind corporate firewall

2010-07-05 Thread greg

I regularly use speech to text on my Nexus One without a wireless
connection.  A local speech to text library and a local (on SD card)
copy of speech data are needed for Android's speech to text to work.
Although I had downloaded them to get speech to text capability in the
emulator, I don't recall having to download either to my Nexus One and
I was under the assumption that the Nexus One is shipped including the
speech to text library and the local speech data.

On the other hand (or in the other direction), the voice input

I think that, at a higher cognitive level, a user remembers what
actions can be performed at a particular activity, not whether or not
a menu exists. Frequently there is also a visual/motor memory
asociated with the menu layout (example: third item = discard
message).

The way a user discovers what actions can be performed is via an
explanation, by an example, and by pressing the menu button to explore
the menu.

[android-developers] Sync Any Database With Google Android

2010-07-05 Thread Tim

Following last year’s successful release of Google Android support for
the MobiForms Developer rapid application development tool, the team
at MobiForms are proud to announce the latest addition of Google
Android support to the MobiForms Sync Server.

The MobiForms Sync Server enables bi-directional data replication,
synchronisation and offline buffering between just about any master
database server and any MobiForms mobile client running on Google
Android and a host of other mobile platforms such as Windows Mobile.
Supported back office database servers include Oracle, SQL Server,
Access, Sybase, IBM DB2, SQLite, HSQLDB and MySQL.

The MobiForms Sync Server is part of the MobiForms Advanced Edition
and includes the MobiForms Developer.

The MobiForms Advance Edition now supports the full mobile development
lifecycle for Google Android database apps including:

- Definition of database replication rules from the master database
- Creation and definition of mobile users
- Building a seed mobile database based on a subset of the master
database
- Creation of a mobile application using the seed mobile database
- Deployment of the mobile application and seed mobile database
- Bi-directional data replication and status updates between the
master database and the mobile client database

Unlike most competing products, the MobiForms Advanced Edition offers
a total solution for a once off licence fee. The licence includes an
unlimited number of MobiForms clients running on Tablet PC, Pocket PC,
Windows CE, Windows Mobile, Windows Smartphone, Symbian and now Google
Android.

I am guessing it's the line saying:

and the immediate cause is the cast from LinkedListRestaurant to

To fix this, you can change the above code to read:

 It is just random i guess, but it happens frequently if you close

 Even deletion and recreation does not have an effect in my case. You

My project doesnt have a XMI file to import from. It consists of 2 modules.

I tried to do Import Sources in ArgoUML and selected the entire project.

  You can override both, but the key is to call the superclass

   As you've seen, the maps documentation is pretty pathetic. What I know
   of the onTap functions has been gleamed from trial and error and
   experimentation. This is how I believe it works:

   onTap(int) determines whether the item at the specified index will
   handle tap events at all. If you return false, the other onTap
   function will always return false.

   onTap(Point, MapView) determines whether an item in the overlay was
   tapped given the touch point, if onTap(int) return true for it's
   index.

   OK, with that, what you can do is:
   return true for onTap(int) always.
   in onTap(Point, MapView) call through to the base implementation to
   determine if something was tapped. And that's it.

   public boolean onTap(point, mapview)
   {
    boolean tapped = super.onTap(point, mapView);
    if (tapped)
    showInfo();
   else
    dropNewItem(point);

   return true; // irrelevant if you only have one itemized overlay
   }

   Hope that helps.

   I don't really agree with this.
   I use onTap(int) to detect if an overlayItem was clicked. And use
   onTap(point, mapview) to handle every other click on the map. I use the
   first to show a ballow, and the second to hide it.

  You can create a custom preference, perhaps subclassing an existing
  one, and implement your business logic there. See here for a custom
  View that I wrapped into a ColorPreference:

 http://github.com/commonsguy/cwac-colormixer


After looking at the source code, I managed to get it work using the
PreferenceActivity with DefaultSharedPreferences.
I write for those who might be interested in this.

The editor.commit() call calls the listener after storing the new
values, so what I was doing was basically correct. A new
editor.commit() call inside the listener  forces the SharedPreferences
to a different value from the one that is being notified (to be more
precise, to the one related to the key that is being notified).

What I did not consider, is that the activity view does not get
updated if I change the preferences from the listener. So the
preference stored was ok but the view was showing an incorrect value.
I resolved reloading the whole activity using :

startActivity(getIntent());
finish();

Hi. im also new. i found a way with paths that works ok.

you have to use
setVideoURI(Uri uri) instead of setVideoPath.
and the media file needs to be in your res folder.
this article explains it: 
http://androidbook.blogspot.com/2009/08/referring-to-android-resources-using.html

maybe someone can give info on how to correctly reference the path (if
you want to use the function setVideoPath).

Thank you very much, I've implemented some parts of the code you gave  
me in my code and works like a charm.
I just had my overlay class in a separate file and i'm not sure how to  
access the variables like the map from there. I'd like to keep the  
format I had before, but if its not possible, this works perfectly so  
I changed my code a little bit and now it works.

Hi all,

I'm using LocationManager.getspeed(); and everytime I use it it comes to
with location.hasSpeed=false ,and the speed is zero ?

So is this something related to ANdroid bugs or this provider doesn't
support speed ?

and What would be the alternatives for it ? should I use the accelerometer
to measure the speed?

 Comparing services and threads is like comparing apples and shoes.

 You do not protect the array from being a race condition between the
 service and the thread.

 You may wish to protect the array from being a race condition
 between two threads. Services by default use only the main application
 thread, unless you are arranging for work to be done in another thread
 yourself (e.g., AsyncTask). In that case, you would want to use
 java.util.concurrent classes, or the synchronization keyword, as Mr.
 Boston suggests. The use of these classes is not specific to Android,
 as they have been in Java for some time.
