I have an application with a service that downloads a set of job data
from a remote web service. It uses this data to update a static
HashMap of Job objects:

public static HashMapString, Object jobs = new HashMapString,
Object();

When it's finished, it sends a message to a handler in
MapViewActivity:

MapViewActivity.handler.sendMessage( new Message() );

to tell it redraw markers on the map based on the data in the jobs
HashMap :

public class MapViewActivity extends MapActivity {
   private static HashMapString, Object markers = new
HashMapString, Object();

public static Handler handler = new Handler() {
public void handleMessage( Message m ) {
super.handleMessage( m );
syncMarkers();
}
};

syncMarkers() reads the jobs HashMap and updates the markers HashMap
based on what it finds. The markers HashMap contains a mapping of
string identifiers to MapOverlay (which extends ItemizedOverlay)
objects.

I'm getting a java.util.ConcurrentModificationException and a force
close from within  syncMarkers() as it tries to iterate over the
markers HashMap. I can see from the backtrace that syncMarkers() is
being invoked from the handler.

I presume this is because the user interface is trying to access the
marker objects at the same time as syncMarkers(). However, I'm very
surprised that this is the case, because I thought the handler would
run in the same thread as the user interface (and not the service's
thread), and so would never conflict. Am I wrong?

[android-developers] Re: ConcurrentModificationException from Handler

Perhaps I'm sending the message from the service to the activity
incorrectly, and syncMarkers() ends up getting called from the
service's thread? If so, would anyone have any advice on the correct
way to send the message?

Re: [android-developers] Re: ConcurrentModificationException from Handler

This exception generally occurs, if you are iterating through it and
changing it simultaneously.

*Note that this implementation is not synchronized.* If multiple threads
access this map concurrently, and at least one of the threads modifies the
map structurally, it *must* be synchronized externally. (A structural
modification is any operation that adds or deletes one or more mappings;
merely changing the value associated with a key that an instance already
contains is not a structural modification.) This is typically accomplished
by synchronizing on some object that naturally encapsulates the map. If no
such object exists, the map should be wrapped using the
Collections.synchronizedMap method. This is best done at creation time, to
prevent accidental unsynchronized access to the map:

 Map m = Collections.synchronizedMap(new HashMap(...));

Re: [android-developers] Re: ConcurrentModificationException from Handler

First, a link to docs:

http://download.oracle.com/javase/1.4.2/docs/api/java/util/ConcurrentModificationException.html

I can see several possible causes for this, and you should get a more
detailed stack trace (more than inside syncMarkers):

1 - You have two threads concurrently accessing the same hash map, and while
the UI thread is iterating, the worker thread comes around and starts
modifying the hash map.

To fix this, you can use synchronized collections:

http://download.oracle.com/javase/1.4.2/docs/api/java/util/Collections.html#synchronizedCollection(java.util.Collection)

Although I would use a different fix - make the data collection be part of
the message. The worker thread would build a new hash map each time, put it
into a message object, and send the message to the UI thread. From that
point on, the collection would be owned by the UI thread.

No concurrent access, no issues with synchronization.

2 - As described in the link above, code that is trying to remove elements
from a collection while iterating, for example:

for (Item i : myHashMap.values()) {
   if (some condition) {
  myHashMap.remove(i.key);
   }
}

You can't do this - use iterator.remove() to remove elements while
iterating.

3 - Code within a single thread that uses iterator.remove on a collection in
a loop, breaking out of the loop early after it finds (and removes) the
object it was going to remove.

I don't know if this is documented anywhere, but I've found that with hash
maps, you have to let that iteration loop run all the way through, until the
iterator's hasNext returns false. The changes (element removals) are applied
at that point, and the collection is then marked as not being in the middle
of a modification.

If you break out of the loop early, after calling iterator.remove, the
change is never applied, and the collection stays marked as being modified.
The next attempt to access the collection will throw the exception as you're
getting.

[android-developers] Re: ThreadSafeConnectionManager timeout...

2011-01-17 Thread lou

Again some news.In order to be understanding, I'll explain again my
problem ( and my idea of why this timeout appears ).
My application contains a service witch connects a websocket ( socket
on port 80 ) and waits push notification.
Activities needs to send some HTTP request. So I think I have to use a
ThreadSafeClientConnManager.
Sometimes, HTTP request from activities doesn't respond and I have a
SocketException : Connection Timed Out, and I don't really know why.

I'm asking if it can be because the websocket block others HTTP
request (but why not all of them?!).
Every idea is good to hear !
Thanks in advance ( and sorry for english mistakes! )

[android-developers] Re: How to copy contacts in phone to another account ?

2011-01-17 Thread Jens

When your SyncAdapter is initialized by the system you should get a
flag in the Bundle you receive from the SyncManager.

So if this flag is present, copy the contacts to your account.

Cool.

I would also recommend that you change your code to send new data in the

If your netwoking code runs on a separate thread - which it should be - then
that global is like a dog waiting to bite you when you least expect.

Why would you try to do that? The OS would get rid of it whenever it feels

Re: [android-developers] Best way to schedule a task?

Sergio,

A Handler only works for as long as your process is alive, which may not
be a good thing.

Use AlarmManager for scheduling - it can wake the phone up (if you need
this) and will reload the process if it was kicked out of memory.

For the actual updates, take a look at IntentService (part of SDK) or
WakefulIntentService (Mark Murphy's enhanced version, Google for it).

Hi!

My application has to be syncronized every 5 minutes against a server.
I have to schedule a HTTP call to my server to get sync.

What is the best way to achieve that?

Now I tried to make a timer with a handler.
I'm passing a message every 5 minutes to execute my action.

Thanks in advance.

Re: [android-developers] Resized Widgets

I believe minWidth comes from the widget_info.xml in your package, so it's
not very useful to the widget's own code.

As for different widget sizes with different displays and launchers -
*sigh*.

2011/1/17 keyboardr keyboa...@gmail.com

 Does anyone know how to allow your appwidget to account for being
 resized (a la LauncherPro or ADW)?  My widget already dynamically
 figures out how many of an item to draw based on the size of the
 widget (meaning I can have multiple providerInfos without having to
 change the provider), but
 AppWidgetManager.getAppWidgetInfo(widgetId).minWidth doesn't get
 changed when LauncherPro or ADW change the size of the widget.

[android-developers] Re: Is there a way to force the application not keep running after close it?

I wanna do that, because I have a task running on background. And i
wanna stop it when the application is closed. This task is doing http
calls every X minutes to sync the application data over internet.

Also, android OS keep the state of the application and open it at the
last activity where the user was on.

I would like to open the application always by the main activity. also
this main activity is doing a login call, which receive the session id
to make more http calls. I have a risk to loose the session id, while
the user is not using the app and it stills in memory for a long time.

[android-developers] Re: Best way to schedule a task?

thanks Kostya,

I don't know if I explained well what i wanna mean when i say sync the
app.

What i try to have sync is the data of the application. I mean, the
user can modify his data through movile device, or accessing via web,
in the future maybe through facebook, etc.

So i think is quite enough if the process run only while the user is
using the application. I think i don't need sync while the user is
doing whatever and my app is on memory. Or maybe yes i don't
know. :D

I am gonna take a look to AlarmManager.

Re: [android-developers] Re: Is there a way to force the application not keep running after close it?

Sergio,

To stop the background task - stop the background task.

It's your own code, so it's under your control. The framework tells you when
things happen via activity state callbacks (onPause / onResume), you just
need to do the right thing with them.

For your second issue:

http://developer.android.com/guide/topics/manifest/activity-element.html

set clearTaskOnLaunch to true.

Re: [android-developers] Re: Best way to schedule a task?

Oh, I see.

You might not need a service or alarms then - a Handler with postAtTime()
should do the trick.

Since you'll be doing networking, make you do it from a background thread,
so as to not block the application's UI.

Android provides a class that makes this easy: AsyncTask.

[android-developers] Big problems with bitmaps, memory management, Log.d

2011-01-17 Thread Matthew Fleming

Hi,

I posted earlier about my need to find a way to load a mutable bitmap.
I need to be able to load a bitmap from an input stream, annotate it,
and save it. At present, the only thing I seem to be able to do is
load an immutable bitmap, copy it, annotate the copy, and then save
that. THIS IS NOT A SOLUTION, because then I need memory for two
copies of the bitmap, and I am working with large images.

COULD SOMEONE FROM GOOGLE PLEASE TELL US WHY the BitmapFactory methods
don't have the option of creating the Bitmap as mutable? A bit heavy-
handed to force the Bitmap to be immutable, don't you think? For that
matter, DOES ANYONE AT GOOGLE PAY ANY ATTENTION TO THIS GROUP?  You
post to the Apple Developer groups, you get an answer (even on the
weekend) from a real live person who knows what he's talking about,
and who is (usually) on the Apple payroll. Not here.

Second question. I figured I would check the available memory before
loading the bitmap, then load it at reduced resolution if necessary.
But Runtime.getRuntime().freeMemory() returns values that make no
sense. For example, if I put this in the onCreate of my first (main)
activity:
long freeMemory = Runtime.getRuntime().freeMemory();
Log.d(tag,String.valueOf(freeMemory));
freeMemory = Runtime.getRuntime().maxMemory();
Log.d(tag,String.valueOf(freeMemory));
I get a total memory of 16,777,216, but free memory of only 472,824.
This can't be right.

The above is with the emulator. When I try it with my Samsung Galaxy
Tab, I don't get any information, because Log.d() doesn't seem to work
at all with the actual hardware. Why is that?

Some real assistance with these problems would be much appreciated.
Google? Anyone home?

[android-developers] Re: Progress Bar without a dialog box

What about making an activity exclusively for displaying the progress
dialog? It sounds like you have no desire to allow the user to do
anything during the fetch process, which I'm against but this would
work. You can do XML for the new activity layout.

[android-developers] Re: Best way to schedule a task?

Ohh thanks, i thought that Timer + Handler will open a new thread
instead of be on the main UI thread.

So, i can combine a timer + handler + AsyncTask, right? If I
understood I think is what you said.

Thanks Kostya!

On 17 ene, 12:27, Kostya Vasilyev kmans...@gmail.com wrote:
 Oh, I see.

 You might not need a service or alarms then - a Handler with postAtTime()
 should do the trick.

 Since you'll be doing networking, make you do it from a background thread,
 so as to not block the application's UI.

 Android provides a class that makes this easy: AsyncTask.

  thanks Kostya,

  I don't know if I explained well what i wanna mean when i say sync the
  app.

  What i try to have sync is the data of the application. I mean, the
  user can modify his data through movile device, or accessing via web,
  in the future maybe through facebook, etc.

  So i think is quite enough if the process run only while the user is
  using the application. I think i don't need sync while the user is
  doing whatever and my app is on memory. Or maybe yes i don't
  know. :D

  I am gonna take a look to AlarmManager.

   Sergio,

   A Handler only works for as long as your process is alive, which may
  not
   be a good thing.

   Use AlarmManager for scheduling - it can wake the phone up (if you need
   this) and will reload the process if it was kicked out of memory.

   For the actual updates, take a look at IntentService (part of SDK) or
   WakefulIntentService (Mark Murphy's enhanced version, Google for it).

Hi!

My application has to be syncronized every 5 minutes against a server.
I have to schedule a HTTP call to my server to get sync.

What is the best way to achieve that?

Now I tried to make a timer with a handler.
I'm passing a message every 5 minutes to execute my action.

Thanks in advance.

Re: [android-developers] Re: Progress Bar without a dialog box

You can put progress indicators into the winow title.

This describes a progress bar that goes from 0 to full:

http://developer.android.com/guide/appendix/faq/commontasks.html#progressbar

It's also possible to show an indeterminate progress bar, or a progress
wheel.

You can also overlay a progress indicator over your activity's content by
using a RelativeLayout or a FrameLayout.

[android-developers] Re: Will no longer support Android 1.5

2011-01-17 Thread String

For my own apps, I don't have a problem supporting 1.5, and I figure that an 
extra 5% is nothing to sneeze at. But then, I've yet to run into anything 
that was really problematic for me to support on 1.5. Some of the resource 
handling is kind of annoying, but not really a big deal.

If I had some core feature that I just couldn't make backward-compatible, 
then yes, I'd drop 1.5 too. But probably not until then, or until the 
install percentage drops a few more points.

Sergio,

2011/1/17 Sergio Luceno slucen...@gmail.com

Ohh thanks, i thought that Timer + Handler will open a new thread
instead of be on the main UI thread.

Java Timer does, so I don't recommend anyone use it on Android.

Use an Android Handler and its postDelayed() - this calls your Runnable on
the UI thread:

http://developer.android.com/reference/android/os/Handler.html

So, i can combine a timer + handler + AsyncTask, right? If I
understood I think is what you said.

Yes, a Handler to schedule updates, and an AsyncTask to execute them.

Beware of orientation changes - carry over your task like this:

Oh, I see.

You might not need a service or alarms then - a Handler with postAtTime()
should do the trick.

Since you'll be doing networking, make you do it from a background
thread,
so as to not block the application's UI.

Android provides a class that makes this easy: AsyncTask.

thanks Kostya,

I don't know if I explained well what i wanna mean when i say sync the
app.

What i try to have sync is the data of the application. I mean, the
user can modify his data through movile device, or accessing via web,
in the future maybe through facebook, etc.

I am gonna take a look to AlarmManager.

Sergio,

A Handler only works for as long as your process is alive, which
may
not
be a good thing.

Use AlarmManager for scheduling - it can wake the phone up (if you
need
this) and will reload the process if it was kicked out of memory.

For the actual updates, take a look at IntentService (part of SDK) or
WakefulIntentService (Mark Murphy's enhanced version, Google for it).

Hi!

My application has to be syncronized every 5 minutes against a
server.
I have to schedule a HTTP call to my server to get sync.

What is the best way to achieve that?

Now I tried to make a timer with a handler.
I'm passing a message every 5 minutes to execute my action.

Thanks in advance.

Re: [android-developers] Re: Anyone know how to calculate speed WITHOUT GPS?

A phone with a camera can used to take pictures of the car's speedometer.

Not very precise (since car speedometers typically lie by a few mph/kph),
but keeps date and time with the image for later reference.

If your car's speedometer is broken, and you see someone you know driving in
the next lane, you can use the phone to call them up and ask.

[android-developers] Re: GPS turned on automatically on some devices?

I seem to remember having a similar problem.  Does your Map app
display the Users current location at any point?

If yes, try calling MyLocationOverlay.enableMyLocation() to start
updates in your MapView's onResume() and
MyLocationOverlay.disableMyLocation() to stop in the onPause() and see
if your GPS problem goes away.

 Hi,
 my HTC users keep complaining that i don't turn off the GPS when they exit

 I don't turn on the gps in the first place. And understood that I am not
 allowed to do it, even if i wanted to.

 Here is my code:
 onCreate:
 locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
 Criteria criteria = new Criteria();
 bestProvider = locationManager.getBestProvider(criteria, false);

 and

 super.onPause();
 locationManager.removeUpdates(this);

 and

 locationManager.requestLocationUpdates(bestProvider, 1, 10, this);

 Anybody knows if HTC turns on GPS by default?

Technically speaking, there is no corresponding [X, Y, Z] for a given [X,

points along Z. However, you can find a particular Z given some more

[android-developers] When NOT to update AppWidget from a Service

My AppWidgets are updated by a Service at user-defined intervals or

Is there any other way to stop updating AppWidgets unnecessarily?

I'd rather target 2.2+ now.. just because its the version that brought in a

that I'll be able to upgrade this year, I would suspect by end of this year
most of the owners would be on 2.2 or later.

Re: [android-developers] When NOT to update AppWidget from a Service

Henrik,

SCREEN_OFF is usually followed by the device entering sleep mode, so that
issue pretty much takes care of itself.

Checking for the current virtual home screen, and currently active home app
among several possibly installed doesn't really fit the widget programming
model - it's more a push rather than pull (as it is with regular views, that
are drawn on demand). I hope that home screen apps have some smarts for that
(and maybe they really do).

I found it very useful to implement checks for stale widget ids in my
apps, so my code doesn't waste time updating 5-10-88 (yes, I've seen that
number) widgets when there is only one on the screen.

http://kmansoft.wordpress.com/2010/06/22/per-widget-options-stale-widgets

Some causes of this are fixed in 2.2, but I'm keeping that code just in
case.

Re: [android-developers] Re: How best to query web repeatedly.

Alright.. little confused Speed limit signs? Every 50 meters a driver passes
one? Or you're trying to pull down speed limit data to let the user know
what speed they are supposed to be traveling (and thus if they are going
over the speed limit)?

Like others said.. is there some way you can pull down ALL the speed limit
data ahead of time for say, a 10 mile radius. Using location information,
gps coordinates, etc, every time the driver gets within a few miles of the
radius edge, pull down more info.. hopefully based on the direction they are
headed and centered on them.

As far as I have seen, speed limits don't change that often that if you can
figure out some sort of radius algorithm to update and assume a good 30
seconds or so for that data, you should be fine.

Re: [android-developers] Re: Will no longer support Android 1.5

I recently ran into some 1.5 issues with my widgets that were caused by a
certain quite popular phone that still runs 1.5 ignoring @dimen values.

So supporting 1.5, understood as some kind of pure Platonic form, is no
problem at all, but dealing with bugs in particular firmware versions is not
fun at all.

For now, both my apps continue to support 1.5, but a new project I'm working
on will only run on 1.6+ - because that's the first version with
multi-resolution support, and one really needs that these days.

[android-developers] Re: When NOT to update AppWidget from a Service

2011-01-17 Thread Henrik Lindqvist

Henrik,

SCREEN_OFF is usually followed by the device entering sleep mode, so that
issue pretty much takes care of itself.

I stop updating on SCREEN_OFF, the start again on SCREEN_ON. This
saves alot, but I was wondering if I can do more.

Checking for the current virtual home screen, and currently active home app
among several possibly installed doesn't really fit the widget programming
model - it's more a push rather than pull (as it is with regular views, that
are drawn on demand). I hope that home screen apps have some smarts for that
(and maybe they really do).

The AppWidget model is very basic, that's why I'am asking on how to
work around the limitations.

I found it very useful to implement checks for stale widget ids in my
apps, so my code doesn't waste time updating 5-10-88 (yes, I've seen that
number) widgets when there is only one on the screen.

http://kmansoft.wordpress.com/2010/06/22/per-widget-options-stale-wid...

Thanks for the tip. I'am already doing this.

Some causes of this are fixed in 2.2, but I'm keeping that code just in
case.

-- Kostya

2011/1/17 Henrik Lindqvist henrik.lindqv...@gmail.com

My AppWidgets are updated by a Service at user-defined intervals or
when certain intents occur. To save battery, I only update the
AppWidgets when the screen is on (SCREEN_ON).

Is there any other way to stop updating AppWidgets unnecessarily?

Only when the home screen is visible?
Only when a specific AppWidget is on screen?

I started development during 2.1 so i never went there.
I'm moving all new code up to minimum 2.2 because thats were 60% of my
customer base is.
That said, I'll support the one app I have thats 2.1 for as long as I
have greater than 10% users.

On that note. It's bogus that the Market doesn't give me any stats on
who my users are. I had to go to ApBrain for that.
How are you tracking what percentage of your users are on what
platform?
There is a GOogle Analytics library for Aneroid, but I haven't tried
implementing it yet.

Re: [android-developers] Is it possible to upload?

Abhilash,

I think what Kumar is suggesting is you do more than just ask someone on the
forum to do it for you. There are some things that are probably not good for
a beginner java developer who is also learning java to try to do initially.
Hence, dig in, read, learn.

As he said, the java APIs.. well really the HTTP calls to make, are what you
want to look into. Android has HttpClient, which has been used by many to
make HTTP calls for API access to services. These are sometimes referred to
as REST calls, depending on if the API is a REST api, or just a simple HTTP
api.

Your original post was 5 days ago. What have you discovered in those 5 days?
Google is an invaluable resource in things like this. I am sure you did a
search for Android Youtube API.. how to call youtube from android, how to
post to youtube from android, and so on right?

I have found most of the time I can find examples of code out there.

On the flip side of this, I myself am looking for the right way to use
HttpClient to send a binary file to any service. I have my own rest service,
and for the fun of learning am making a simple camera app for my wife..
where by it takes a snap, then sends the image to a service where it will be
emailed out to many people at once. I can't seem to get the actual byte[] of
the image to connect to my service yet. It's probably similar to what you'll
need to do for a youtube post of a video.

The fun of discovering. :)

  I wanna do that, because I have a task running on background. And i

  Also, android OS keep the state of the application and open it at the

[android-developers] Using onItemSelected with conditionals

2011-01-17 Thread zizzfusion

Hello I'm trying to think of the best way of tackling this - I'm not
using a database or inflating data dynamically so instead I just want
to load a different activity depending on which Spinner selection is
made. I'm in the early stages of working with Android so here's where
I'm at:

public class ItemSelected implements OnItemSelectedListener {

  public void onItemSelected(AdapterView? parent, View v, int pos,
long id) {
  if ((parent.getItemAtPosition(pos).toString()) == Selection 1)
{
  startActivity(new Intent(this, activity_1.class)));
  } else if {
  // ditto for activity 2 and so on }
  }

  public void onNothingSelected(AdapterView? parent){
  Toast.makeText(parent.getContext(), No selection made,
Toast.LENGTH_LONG).show();
  }
}

Would a conditional set of statements work something like this or can
I load the activities through an array as could be done with a simple
set of strings.

Sure, but you could simplify this to a switch statement:

switch (pos)
{
 case CONSTANT_FOR_SELECTION_0:
 launchActivityForSelection0();
break;
// etc.
}


 or can I load the activities through an array as could be done with a
 simple set of strings.


I have no idea what that means.

[android-developers] possible enhancement of Android SDK-NDK integration?

2011-01-17 Thread Ajay Prabandham

Dear community,
I was browsing through the Android NDK info on 
the Android developers website, and found that currently only NDK ACTIVITY 
components can be invoked from SDK components. I an curious to know whether 
adding the capability to NDK Services and Content Providers to be invoked 
from the Java components, would be a good project idea.
The questions that crop up are:


1. Is there any inherent property of the SDK/NDK that prevents Services to 
be accessed in this way?
2. Is anyone/any group already working on this feature?

The intention is to provide cross-language RMI, something that middleware 
such as CORBA support inherently.

Regards,
Ajay

Re: [android-developers] Does Android provide API to enable my IME

Yah, I've had a tone of trouble with my users not understanding how to 
enable to my IME's.
I don't want to do it for them however. What would be good is a way to allow 
them to click buttons in my app to enable it.

At the moment, I found that providing a launch app with installation 
instructions has reduced my support tickets by a huge amount, however by far 
the most support requests i get are still users who don't understand how to 
enable the darn thing.

My stats are from Google Analytics. If you use it and explain what you

Not surprised. People here probably have their own projects going on I get
the impression that the knowledge pool for GL on Android is very small.

Maybe try gamedev.net - great site for general game development stuff and
they have a Help Wanted section.

here is how i define my main activity.

   To stop the background task - stop the background task.

   It's your own code, so it's under your control. The framework tells you
  when
   things happen via activity state callbacks (onPause / onResume), you just
   need to do the right thing with them.

   For your second issue:

   set clearTaskOnLaunch to true.

I wanna do that, because I have a task running on background. And i
wanna stop it when the application is closed. This task is doing http
calls every X minutes to sync the application data over internet.

Also, android OS keep the state of the application and open it at the
last activity where the user was on.

I would like to open the application always by the main activity. also
this main activity is doing a login call, which receive the session id
to make more http calls. I have a risk to loose the session id, while
the user is not using the app and it stills in memory for a long time.

I want to run a web application on Android based tablet and have it

Is it possible to do so out-of-the-box or do I have to write my own Android

Also, inside that web-app I show YouTube video, will Android browser (chrome

You will have to write your own app for that. I'm not sure how you expect to
run a web application without a browser out of the box.

More than likely, the user will get the option of how they want to view the
video - either in the browser or through a dedicated YouTube app.

[android-developers] Window token is always null

2011-01-17 Thread APF

I find that View.getWindowToken() always returns null, even when
invoked from the main Activity during onCreate.  For example:

TextView tv = new TextView(this);
tv.setText(Hello, Android);
setContentView(tv);
tv.getWindowToken(); // will equal null

Manually adding it to the window manager (addView) doesn't help
either.

When does a View have a window token?  How do I get a valid window
token?

TIA.

[android-developers] Problem with large number of markers on google map

2011-01-17 Thread bobetko

I am working on an Android app that already exists on iPhone.

In the app, there is a Map activity that has (I counted) around 800
markers in four groups marked by drawable in four different colors.
Each group can be turned on or off. Information about markers I have
inside List. I create a mapOverlay for each group, then I attach that
overlay to the map. I strongly believe that coding part I did
properly. But I will attach my code anyway...

The thing is, my Nexus One can't handle map with all those markers. It
takes around 15 seconds just to draw 500 markers. Then when all drawn,
map is not quite smooth. It is sort of hard to zoom and navigate
around. It can be done, but experience is bad and I would like to see
if something can be done there. I know if I avoid String  Double
conversion, I could save some time, but I doubt that would be
significant.

iPhone seems doesn't have problems showing all these markers. It takes
roughly about 1-2 seconds to show all of them and zooming and panning
is not that bad. Slow down is noticeable but still acceptable. I
personally think it is no good to draw all those markers, but app is
designed by somebody else and I am not supposed to make any drastic
changes.

I am not sure what to do here. It seems I will have to come up with
different functionality, maybe use GPS location, if known, and draw
only markers within some radius, or, if location not known, use center
of the screen(map) and draw markers around that. I will have to have
reasonable explanation for my bosses in case I make these changes.

I appreciate if anybody has any idas.


And the code:


ListOverlay mapOverlays = mapView.getOverlays();
Drawable drawable =
this.getResources().getDrawable(R.drawable.pin_blue);
drawable = this.getResources().getDrawable(R.drawable.pin_blue);
ArrList = appState.GetSleepArrList();
ItemizedOverlay itemizedoverlay = new ItemizedOverlay(drawable,
this);
...
...
   for (int m = 0; m  ArrList.size(); m++) {
tName = ArrList.get(m).get(name).toString();
tId = ArrList.get(m).get(id).toString();
tLat = ArrList.get(m).get(lat).toString();;
tLng = ArrList.get(m).get(lng).toString();;
try {
lat = Double.parseDouble(tLat);
lng = Double.parseDouble(tLng);
p1 = new GeoPoint(
(int) (lat * 1E6),
(int) (lng * 1E6));
OverlayItem overlayitem = new OverlayItem(p1, 
tName, tId);
itemizedoverlay.addOverlay(overlayitem);
} catch (NumberFormatException e) {
Log.d(TAG, NumberFormatException + e);
}
}
mapOverlays.add(itemizedoverlay);
mapView.postInvalidate();




public class ItemizedOverlay extends ItemizedOverlayOverlayItem
{
private ArrayListOverlayItem mOverlays = new
ArrayListOverlayItem();
private Context mContext;
public HelloItemizedOverlay(Drawable defaultMarker, Context 
context)
{
super(boundCenterBottom(defaultMarker));
mContext = context;
}

public void addOverlay(OverlayItem overlay)
{
mOverlays.add(overlay);
populate();
}
@Override
protected OverlayItem createItem(int i)
{
return mOverlays.get(i);
}
@Override
public int size()
{
return mOverlays.size();
}
@Override
protected boolean onTap(int index)
{
final OverlayItem item = mOverlays.get(index);
... EACH MARKER WILL HAVE ONCLICK EVENT THAT
WILL PRODUCE CLICABLE
... BALOON WITH MARKER'S NAME.
return true;
}
}
