 I found this question asked over a year ago but no solution was found:

 http://groups.google.com/group/android-developers/browse_thread/thread/15d8e7e8bc46d279/4e11259e78e6d654

 Essentially, I want to use a LinearLayout with horizontal orientation,
 but when the child views' total width is greater than the width of the
 screen, to wrap to the next line/row. In particular, I'm using a
 RadioGroup (with radio buttons determined at runtime) where it would
 be much better to do this wrapping rather than use vertical
 orientation.

 Is there a layout that supports this?

No, sorry. You theoretically can create your own custom layout that has
this property.

[android-developers] MapView Overlay that does always keeps an item selected?

2010-02-13 Thread Fabian Sturm

Hi,

I want to add an ItemizedOverlay to a MapView that always keeps one
OverlayItem as the selected one. I indicate this by using a
StateListDrawable with two different marker drawables.

But right now, whenever I tap on the map and not hitting a marker, the
last selected item will get deselected. But I always want to keep the
last item selected until a new one is hit.

I already tried to intercept e.g. onTap, but this only lets me
completely disable the tap handling.

Any suggestions what to do about this?

Thanks a lot, Fabian

Oh yes and i forgot :

www.androlib.com now lets you register as the developper of an app.

You can then add a longer description which I don't find that useful,
but you can see all the comments made by people on your apps on all
languages.

I find that absolutely amazing that this was not build-in on the

 But as soon as you just see it for what it is, an simple access to the

 know what's happening with our apps.

 I personnaly use flurry(flurry.com) which gives analytics and I

 Of course if you're on the race to be in the top 25, then it's a real
 problem that your downloads are not counted...For others, well, not so

[android-developers] Re: How to start an Activity from a Service and getting a result from it

2010-02-13 Thread Menny

OK. I'll be explain my needs:
I'm the author of AnySoftKeyboard (http://
softkeyboard.googlecode.com).
The reason I made this keyboard, is to provide alternative layouts in
the on-screen keyboard (e.g., Hebrew, Russian, DVORAK, etc. and of
course, qwerty).
But the keyboard APK gets bloated with all the layouts, and
dictionaries etc
So, I wanted to move all layouts to external packages: one layout (or
several) per package.

All the data I need to create a layout are the resource IDs of the
layout, the dictionary and several other stuff, all of which can be
retrieved using a ContentProvider.
But I need the ContentProvider's URI.
So I thought that starting an Activity and getting a result from it
(startActivityForResult call) will be perfect for me.

I do not need any UI to popuup (actually, I prefer that none will), I
get need to get some data from the external package.

So, these are my needs. Anyone can suggest a way?

Thanks,
Menny

[android-developers] Re: No light sensor and/or proximity sensor detected on Hero?

2010-02-13 Thread mileoresko

I used the ddms tool, and I am not sure what the Proximity Sensor app
uses.
As far as I can see it reads something from a file, then does some
character decoding and stuff like that, so I don't think it uses the
SensorManger API at all.

Nonetheless, I would like to use the SensorManager API to fetch data
from the Light Sensor. If that is not possible, I would like to know
why it isn't.
If there is an alternative way to access this sensor's readings, I
would appreciate if someone could share it with me.

Thanks

[android-developers] is charset decoding terminal dependant?? (UTF8/iso-8859-1 question)

2010-02-13 Thread Thierry Legras

Hello,

I'm having troubles to correctly display strings with é è ... characters
extracted from an html page (iso-8859-1).
I am reading the html page as iso-8859-1 (using xerces XMLInputSource(null,
null, null, myHTTPRequestContent, iso-8859-1), searching and extracting
some specific strings with a nekohtml sax filter, then display the result in
some view with something like:

myString.getBytes(iso-8859-1)

This is working pretty good on some devices, but in some other, like all my
AVD, the french é è etc. characters are incorrectly displayed. More
strangely, it is working on my HTC Hero, but not on my wife's own HTC Hero
(not bought at same place). I tried to change the locale to french on the
AVD but it did not changed anything.

On these devices, it seems that using directly myString ( or
myString.getBytes(UTF8) ) is correct.

I see other applications that seems to handle this issue by providing an
option force UTF8, but i would prefer definitly a generic one!

Any clue?

Re: [android-developers] Re: Help needed with parsing some XML data !

2010-02-13 Thread Thierry Legras

Hi,

I have a similar problem. I am parsing iso-8859-1 html page with a sax
parser but having trouble to display it on _some_ devices (characters é è
... are replaced by random symbols).
On some devide i have to use myString.getBytes(iso-8859-1) to display it
correctly, and on some other devices, myString will be displayed correctly.

The best solution i cold ifnd so far is to provide a user option like force
utf8 or force iso-8859-1 that the user can check if having problem.

2010/2/4 MobDev developm...@mobilaria.com

Well,
to be honest your first idea was also mine :P So I already looked via
Google but to be honest I haven't found that many clear discussions/
explanations...
I also tried idea 2 and this is what I got :

Congratulations

The document located at http://x was successfully checked as
well-formed XML. This means that we were not able to determine the
exact document type, but that the document passed the XML well-
formedness syntax check. If you wish to wish to perform formal
validation of the document, you can use the Document Type: option of
the validator.

But also this has been found, even though I do not know how important
this is :
The DOCTYPE Declaration was not recognized or is missing. This
probably means that the Formal Public Identifier contains a spelling
error, or that the Declaration is not using correct syntax, or that
your XML document is not using a DOCTYPE Declaration.

Validation of the document has been skipped, and a simple check of the
well-formedness of the XML syntax has been performed instead.

Als, just to point out, at this point i CAN read out the XML stream by
using the
Xml.parse(is, Xml.Encoding.ISO_8859_1, new ExampleHandler(myAdapter));
method...
The only problem that remains is when I try to write on-screen the
values...
Btw, is there a way to trasform such a String (for example from a
Country ID=2 CName=Åland eilanden/ tag) to utf-8 ?
I have experienced such a problem on the iPhone some time ago, it also
received the data as ISO-8859-1 but the STring had to be encoded to
UTF8 to be shown correctly onscreen

On 4 feb, 11:47, Frank Weiss fewe...@gmail.com wrote:
I have two ideas for you, Mobdev:

1) Google for not well-formed (invalid token) and see what other people
have found regarding this error.
2) Go to validator.w3.org and see if the XML file in question is indeed
valid or not.

Please let us know what you find out.

[android-developers] Force Close just restarts the app?

2010-02-13 Thread Steeler

I've noticed that whenever I introduce some new awful bug to my app
and it crashes, Android just keeps starting it up over and over again.
I eventually have to hit the dial button on the phone just to make my
app lose focus.

I searched this group's posts and the developer documents... I can't
find anything about this. Is this usual behavior? If so, is there some
way to disable it? Maybe it's just my coming from a desktop
background, but I kind of think that when something is closed, it
should stay closed, especially if the reason it was closed was that it
crashed. And of course, I hope my final app never force closes, but
with all the different hardware you never know...

[android-developers] Re: Hey Mr or Ms Moderator...

2010-02-13 Thread Maps.Huge.Info (Maps API Guru)

I can comment on how the groups system works in general but not
specifically how this group is handled...

Usually, when a new member makes a valid post, the option to always
allow is selected which not only posts the message but also takes the
new member off of moderation. If the post is iffy then it may be
allowed, removed or posted. Removed or posted doesn't take the member
off of moderation. If a message is off topic, the choices are to
remove the message or mark it as spam. A spam selection both removes
the message and bans the member.

I moderate on the maps forum, that's how we handle it. This forum is
probably handled in a similar manner.

One thing to take into consideration is how long it takes for a
moderator to get to your message. Many members post a message, it
doesn't show immediately, then they post it again two, three even more
times hoping that somehow it will get through but all that does is
fill the moderation queue up with duplicate messages. Once you make a
post, you'll just have to wait for one of the moderators to get around
to releasing it. Remember, forum moderation isn't their primary or
only job. Be patient and your message will get posted eventually,
probably within a day or so.

[android-developers] Extended Resources Strategy

2010-02-13 Thread Evan Ruff

Hey guy,

I was wondering if some of the experts out there could help me with an
extended resource strategy? I'm interested to hear about some of the
accepted best practices that everyone is using to tackle some of the
issues that arise when you've got a ton of graphics/resources.

I just recently upgraded all the resources in my application to have
separate hdpi and mdpi graphics. After struggling with and figuring
out the dpi-based methodology that android employs I have to say that
I'm very impressed with the design. The application looks absolutely
fantastic and renders great on a number of devices. Really not that
much additional coding once you get it all figured out. The problem I
have now is that my application is over 4mb.

The application is heavily PNG driven and, even after punypng*
optimizing everything, it is still a huge amount of graphics. There
are over 150 different icons and headers used in the application. When
you add another set for high resolution, you're looking at over 300
images that drive the user experience. Currently, everything is thrown
in the /res folder and managed from there through a lookup dictionary.
Functionally it works 100%, but I'm worried about the massive amount
of transfer time when people upgrade.

Has anyone tried breaking out the images and then downloading those
separately from the main application? What I'd like to do is publish
the APK to the market and have it managed as usual. Then, depending on
the device, I'd like to go to an S3 store and download a ZIP of the
graphics. Once the download was complete (1.3mb for hdpi, 500k for
mdpi) I would like to move the graphics to the storage card and unzip
them there, referencing them from the main application on the card.

Is this a good strategy? Am I missing anything regarding the auto-
scaling and such? Other than the various synchronization issues does
anyone see any problems with this approach? Would there be a
noticeable performance hit loading the graphics from the SD Card as
opposed to memory? Does Android include native zip/unzip libraries?

Thanks for all your help and input!

Are you sure you want to do this? This goes against the standard behavior of

or other obstructing view). But if you really want to...

But right now, whenever I tap on the map and not hitting a marker, the
 last selected item will get deselected. But I always want to keep the
 last item selected until a new one is hit.



 I already tried to intercept e.g. onTap, but this only lets me

 Any suggestions what to do about this?


Keep track of the last selected item. In onTap() if the currentFocus() is
null, setFocus() to the last selected item you saved. If it's not null,
update your reference.

You can also use the same idea but using the OnFocusChangeListener on the
ItemizedOverlay to determine if a new item has been focuses or not.

2010-02-13 Thread Clankrieger

Thank you for your hints.

I already reposition to 0 in my getBuffer methods similar to this:

public Buffer getBufferVtx() {
  m_VtxBuffer.position(0);
  return m_VtxBuffer;
}

Also, the buffers do not get recycled between glDrawElements calls.
What did you mean with this :

 Another rough one was that in Android 1.5 putting an array into a
 buffer using a non-zero offset into the array to start from doesn't
 work. Works in later versions of Android, however.

I am not using multiplexed arrays, thus each array starts at index 0
(for color, vertices and texcoords). The data it self is absolutely
fine - I validated this in my PC version.

Is there any way to force that the GL interface on Android has
rendered all data provided during the OnDraw event of the render? How
bad/important are the clientstates (glEnableClientState) on Android?
Can I recycle the ByteBuffers every frame or should I have several
that get swapped each frame - I`ve read somewhere that GlSurfaceView
gets double-buffered - maybe I simply change the bytebuffers in an
OnDraw call where it gets used by a native render call?

 I haven't run into anything like that myself. I do often run into
 issues that can cause the data to be incorrectly offset or otherwise
 messed up, however, which might look similar.

 The position of the buffer is important when you call glVertexPointer,
 for example. So if the way you filled the buffer changed the position,
 it has to be rewound or otherwise set back to where you want it before
 you call glVertexPointer.

 Another rough one was that in Android 1.5 putting an array into a
 buffer using a non-zero offset into the array to start from doesn't
 work. Works in later versions of Android, however.

 Another issue is that the way the glVertexPointer call works is that
 it doesn't consume the actual data. It is just setting the pointer to
 the data. So changing the data before your other calls actually cause
 it be used later on would cause trouble.

  Hi,

  I got an issue while rendering a number of meshes on aGlSurfaceView
  renderer: The meshes are sometimes broken or are not updated on screen
  during my render call. The whole 1.6 application is running single

  glVertexPointer(3, GL10.GL_FIXED, 0,
  (IntBuffer)_pMesh.getBufferVtx());

  It looks a bit like the native interfaced get spammed by my render
  calls and do not get enough time to natively actually draw the data?
  It behaves completely the same on emulator and an actual phone. I am
  using the rendering pipeline on a PC project as well were is works
  absolutely fine.

  I begun feeling really desperate and dumb because I can't get this
  working properly since days. :(

  Thank you!

Re: [android-developers] is charset decoding terminal dependant?? (UTF8/iso-8859-1 question)

2010-02-13 Thread Frank Weiss

First, some clarifications. Locale has nothing to do with character
encoding. Java stores all character data internally as 16-bit Unicode,
regardless of locale.

I suspect that myString.getBytes(iso-8859-1) is erroneous. I'm assuming
that myString is of type java.lang.String. What are you doing with the
result and why do you want to encode a sequence of Unicode characters back
to ISO-8859-1 (Latin1)?

Re: [android-developers] Force Close just restarts the app?

What generally happen when a process crashes is that it is killed, the
crashing activity removed, and then the system restarts the next thing on
the activity stack.  If you had an activity before that one on the stack
then that activity will be restarted.

This does allow you to write a pathological case where you have one
activity, that starts another, and the second activity crashing during
initialization.  That activity will be removed, the processed killed, and
then the process restarted to display the previous activity which again
launches the crashing activity.

A future version of the platform will probably just remove all activities
owned by the app when it crashes.  This is a little excessive and I would
like to be a little better about it, but yes this case is annoying.  (For
example if a browser has multiple activities for each tab/window, it would
be unfortunately to lose all of them if you get a crash while using one of
them.)

Re: [android-developers] Re: How to start an Activity from a Service and getting a result from it

This sounds much more complicated than you need.  If you just want to load
resources from another .apk, you don't need any code in it at all -- just
use Context.createPackageContext() to get the context for the other package
and load its resources from there.

And if you don't need any UI, and really do need to execute code in the
other .apk, then you said you already have a content provider so why not
just call that?  Or a broadcast receiver?  Or a service?

Also if you really do need to run the code in the other .apk, please
consider using android:sharedUserId with all of your .apks and having them
all run in the same process, so you don't need to spin up multiple
processes.

 OK. I'll be explain my needs:
 I'm the author of AnySoftKeyboard (http://
 softkeyboard.googlecode.com).
 The reason I made this keyboard, is to provide alternative layouts in
 the on-screen keyboard (e.g., Hebrew, Russian, DVORAK, etc. and of
 course, qwerty).
 But the keyboard APK gets bloated with all the layouts, and
 dictionaries etc
 So, I wanted to move all layouts to external packages: one layout (or
 several) per package.

 All the data I need to create a layout are the resource IDs of the
 layout, the dictionary and several other stuff, all of which can be
 retrieved using a ContentProvider.
 But I need the ContentProvider's URI.
 So I thought that starting an Activity and getting a result from it
 (startActivityForResult call) will be perfect for me.

 I do not need any UI to popuup (actually, I prefer that none will), I
 get need to get some data from the external package.

 So, these are my needs. Anyone can suggest a way?

   Now, from each such package, I need to get a ContentProvider URI.

   The problem is that there is no way to call startActivityForResult

The source code is in the open source tree in the development project
under apps/Development.  You can build and modify it.  You can also look at
how it is poking things to get the specific features you want and write your
own app to do that.  (But please if you are using non-public APIs do not put

Re: [android-developers] Re: onActivityResult is called immediately after startActivityForResult

The action or category (or data or mime type) in the launching intent
doesn't matter at all for what will happen with the result.

When you are in your second activity, you can try adb shell dumpsys
activity to see the current activity stacks (they are the first thing
printed; there is a lot more).  Your sub-activity should be on top, and it
will include where its result will go to, if there is a target.

The code you posted look okay to me, but you didn't include your code that
actually starts the activity and that is the most likely culprit -- if you
use startActivityForResult() you should be guaranteed to get -some- result
back, no matter what.

Re: [android-developers] is charset decoding terminal dependant?? (UTF8/iso-8859-1 question)

2010-02-13 Thread Thierry Legras

Thanks for your reply.

yes this is a java.lang.String. Indeed all i want to do is to correctly
display the string in some View.

Ok i got the point about java String being 16 bits. If so, and as it is not
well displayed, i guess this means it was not properly created at first.

Maybe this issue is more related to my (bad) use of xerces when i initialize
the xerces XMLDocumentFilter object.

XMLParserConfiguration parser = new HTMLConfiguration();
parser.setDocumentHandler(filter); // filter is a
XMLDocumentFilter
XMLInputSource source = new XMLInputSource(null, null,
null,myHttpResponse.getEntity().getContent(), iso-8859-1);
parser.parse(source);

I will check more in detail in xerces ressources, this probably is not an
Android related topic after all.

[android-developers] selecting language from within the app rather than by locale of the system settings

2010-02-13 Thread mot12

Hi,

Any help on this would be much appreciated.

I would like to give the users of my app the possibility of selecting
a language from within the application. All languages are supplied the
standard way via the values-?? resource directory.

However, I don't want Android to select which resource directory to
use but let the user decide instead.

Any ideas how to accomplish that?

The rationale for this:
- some languages are not supported by the Android framework and can
not be selected as a locale via the system settings
- if you buy a phone in Spain, it will typically not have a system
setting for Russian language, if you purchase in Russia, you will have
that setting. So a Russian person in Spain would prefer using the
Russian language included with the app, but can't access it

thanks for any suggestions,
Martin

Re: [android-developers] Re: unable to bind to a service

If you haven't declared an intent-filter in your manifest, then the
component will be private to that .apk.  You can make it public with either
android:exported=true or defining an intent-filter.

HOWEVER..  PLEASE be super careful about doing this.  Did you realize that
you are in the process of creating a nice big security hole, where you let
any application get the user's current location without needing permission?

Why are you doing this?  The location APIs let applications get the current
location.  Why are you republishing that information in your own service?
 And why does this need to be in a separate .apk?

My first instinct is for you to just not do this.  Please.  If you really
think you need to do it, you need to seriously think about what you are
doing with security.  You would be very much best off putting all of this
stuff in one .apk so you don't leak information to others.  If for some
reason you really think you need to have this separate (and take the
overhead of multiple processes and all that), then you need to step back and
take serious consideration of security and applying permissions to enforce
it, how your .apks are signed, install ordering issues with granting
permissions, etc.

Re: [android-developers] MapView Overlay that does always keeps an item selected?

2010-02-13 Thread Fabian Sturm

Hi,

thanks for the hint! I already tried to implement this, but am now stuck
with that setFocus works, but it does not raise the OverlayItem to the
top. As is done if I select the item with a tap.

So is there any chance to really select an item and not merely focusing
it?

 Are you sure you want to do this? This goes against the standard 
 behavior of deselecting when clicking somewhere on the map (possible
 to remove a popup or other obstructing view). But if you really want 
 to... 

The reasoning behind this is, that I don't have a popup when I select an
item. But I have a statusbar which is permanently visible and shows
details to the selected item. Therefore it makes sense to always have
one item selected.

Thanks a lot, Fabian

[android-developers] Re: Force Close just restarts the app?

2010-02-13 Thread Steeler

I only have one activity in this app, but it still does it.

Wouldn't a better way to go be just to have a manifest attribute for
each activity that says whether it should be removed, restarted, or
left alone?

On Feb 13, 1:31 pm, Dianne Hackborn hack...@android.com wrote:
What generally happen when a process crashes is that it is killed, the

This does allow you to write a pathological case where you have one
activity, that starts another, and the second activity crashing during
initialization. That activity will be removed, the processed killed, and
then the process restarted to display the previous activity which again
launches the crashing activity.

A future version of the platform will probably just remove all activities
owned by the app when it crashes. This is a little excessive and I would
like to be a little better about it, but yes this case is annoying. (For
example if a browser has multiple activities for each tab/window, it would
be unfortunately to lose all of them if you get a crash while using one of
them.)

[android-developers] Re: Pinch-zooming on maps gives no feedback

2010-02-13 Thread CaptainSpam

I just tested this out, and it seems like it does work (that is,
draw() IS getting called after a zoom).  And, it doesn't seem to be
hogging on system resources, calling draw repeatedly.  So all in all,
I'd say it's a workable workaround, though a cleaner interface in the
API would be more convenient.

Thanks!

  However, my app has a need to know when the user has zoomed the map.
  As it stands now, I've just been watching over the only way this has

  MapController commands to MAKE the map zoom), so developers don't
  appear to have any way of knowing if the zoom level was changed
  outside of their control (i.e. pinch-zooming) apart from constantly
  polling the MapView.

  Is there any good way around this, or is an update like this in the

[android-developers] Picture while starting app

2010-02-13 Thread Nox

Hello everybody,
I´ve got a problem with my current app.
I want to see a picture while starting the app.
I´ve already tried to use use a while-method but if I launch the app it
´ll wait a few seconds but it will not appear my picture.

In a simple Java project I would use this command and I also don´t
know what kind of command I´ll have to use to see the picture:



  public class waiting {
public static void main(String[] args) {
int seconds = 5;
System.out.println(Waiting:  + seconds);
try {
Thread.sleep(5000);
} catch (InterruptedException e) {}
System.out.println(Done);



}
}


But if I use the command in Android it will not work!!!

Do you know what to do?

Please help me!!!

With kind regards


Viktor B.

Hmm ... it should, as the currently focused item should be drawn last (on

to force a redraw and see if that works?

Virtually none of that should be used in an Android application.

Bear in mind that *nothing* you do in, say, onCreate() to affect the UI
will take effect until *after you return from onCreate()*. Sleeping on
the main application (UI) thread will only make things worse.

 Do you know what to do?

No, because you haven't really defined the problem in Android terms.
Saying I want to see a picture while starting the app leaves many
possibilities.

What is the trigger for making the picture go away? Is it a user event
(e.g., a click)? Is it the passage of a fixed amount of time? Is it when
something you are doing in a background thread (e.g., AsyncTask) completes?

[android-developers] Re: How to start an Activity from a Service and getting a result from it

2010-02-13 Thread Menny

I don't know what the other ContentProviders URI are.
They can be anything, I want to release my keyboard service, and then
release layouts as I need.
This means that, somehow, the keyboard service needs to know which
layout packages are installed on the device, and what are the URI of
their content-providers.

I don't want to use sharedUserId, since I want to give other
developers the option to create their own layouts.

On Feb 13, 9:36 pm, Dianne Hackborn hack...@android.com wrote:
This sounds much more complicated than you need. If you just want to load
resources from another .apk, you don't need any code in it at all -- just
use Context.createPackageContext() to get the context for the other package

And if you don't need any UI, and really do need to execute code in the
other .apk, then you said you already have a content provider so why not
just call that? Or a broadcast receiver? Or a service?

Also if you really do need to run the code in the other .apk, please
consider using android:sharedUserId with all of your .apks and having them
all run in the same process, so you don't need to spin up multiple
processes.

OK. I'll be explain my needs:
I'm the author of AnySoftKeyboard (http://

The reason I made this keyboard, is to provide alternative layouts in
the on-screen keyboard (e.g., Hebrew, Russian, DVORAK, etc. and of
course, qwerty).
But the keyboard APK gets bloated with all the layouts, and
dictionaries etc
So, I wanted to move all layouts to external packages: one layout (or
several) per package.

All the data I need to create a layout are the resource IDs of the
layout, the dictionary and several other stuff, all of which can be
retrieved using a ContentProvider.
But I need the ContentProvider's URI.
So I thought that starting an Activity and getting a result from it
(startActivityForResult call) will be perfect for me.

I do not need any UI to popuup (actually, I prefer that none will), I
get need to get some data from the external package.

So, these are my needs. Anyone can suggest a way?

So I want to start the external Activity and the external activity

The problem is that there is no way to call startActivityForResult

The bottom line:
Can anyone suggest a way to get ContentProvider URI from an external

Another alternative is to still use Context.createPackageContext(), but
primarily as a bootstrap. The APK would publish its content URI in a

which you would then use.

2010-02-13 Thread dane131

well ok i understand the risk..and i will change the architecture
but anyway i have a problem to bind to a service of another apk even
if its attribute is exported=true
i wonder if i do someting wrong in my procedure:

in the remote apk i generate an interface from an aidl file and make a
service and with an anonymous class in it
that extends MyInterface.Stub.

In the client package i have an activity that has an object of type
MyInterface (that is the mservice object of type IGps in the example
above ) that i use it in order to call the methods exposed by my
remote service.However i don't have visibility of that interface since
it is in a remote package so i copy/paste the aidl from the remote
package into my client package and generate the interface as well ( i
also change the package name in the aidl file to that of my client
package) so now i have visibility of the ineterface..but this does not
seem to work ..do i make any mistake?

That is difficult to answer, as remote services are difficult to debug

You should compare your implementation to others that demonstrably work.
I would imagine there is a remote service sample in the SDK samples
someplace -- search for AIDL files.

Here are another pair of projects implementing a remote service and a
client for it:

data or something in the background.. then when all done, starts up and the
image goes away. Do a search here for splash screen. There are plenty of
examples that show how to do it.

 Virtually none of that should be used in an Android application.

 Bear in mind that *nothing* you do in, say, onCreate() to affect the UI
 will take effect until *after you return from onCreate()*. Sleeping on
 the main application (UI) thread will only make things worse.

  Do you know what to do?

 No, because you haven't really defined the problem in Android terms.
 Saying I want to see a picture while starting the app leaves many
 possibilities.

 What is the trigger for making the picture go away? Is it a user event
 (e.g., a click)? Is it the passage of a fixed amount of time? Is it when
 something you are doing in a background thread (e.g., AsyncTask) completes?

Re: [android-developers] Re: New sales have come to a halt Re: Developer console stopped updating?

I am curious why the heck Nexus 1 already got an update and yet Moto Droid,
which is supposed to be an Android experience device STILL hasn't got the
2.1 update. There seems to be no communication what so ever from Moto about
the update. We were told that within days after 2.1 came out we'd see it.
Then we had strong rumors that it would be end of January. Now it's
completely quiet with no info at all. Anyone heard about this supposed 2.1
update for Droid? I am fine if it takes another month if they are fixing
issues, like the big problem with multi-touch.. but at least some for of
communication would be nice.

But as soon as you just see it for what it is, an simple access to the

I personnaly use flurry(flurry.com) which gives analytics and I

[android-developers] Re: Broken Meshes / not synchronous while rendering GlSurfaceView

2010-02-13 Thread Lance Nanek

glFlush or glFinish might allow something like that:
http://java.sun.com/javame/reference/apis/jsr239/javax/microedition/khronos/opengles/GL10.html#glFinish()
http://java.sun.com/javame/reference/apis/jsr239/javax/microedition/khronos/opengles/GL10.html#glFlush()

I've never had to use or look into them myself. Maybe because
GLSurfaceView calls eglSwapBuffers between onDrawFrame calls, which
does an implicit flush anyway, and I only modify the buffers pointed
to by the pointer methods in those onDrawFrame calls right before use.

Re the Android 1.5 issue, I was referring to this method:
http://developer.android.com/intl/fr/reference/java/nio/IntBuffer.html#put%28int[],%20int,%20int%29

I use methods like that a lot because I benchmarked that it was faster
to update the vales in an array and then put the array into a buffer
than it was to put a lot of values into a buffer one by one.

So, for example, I have an atlas texture generation script that also
generates an array of all the texture coordinates my sprites might
ever want. I tend to arraycopy whole sections of that array into other
arrays or put them into the single shared texture buffer I use.

Similarly, in the latest game I'm working on, all the positions for
all the near screen sprites get set in one array which only gets put
into the single shared vertex buffer they all use right before use in
onDrawFrame.

Using the same buffer for multiple entities allows you to use one draw
command for each group of them that needs various state, like
different blending functions, rather than one draw command for each of
them.

On Feb 13, 2:08 pm, Clankrieger tob...@googlemail.com wrote:
Thank you for your hints.

I already reposition to 0 in my getBuffer methods similar to this:

public Buffer getBufferVtx() {
m_VtxBuffer.position(0);
return m_VtxBuffer;

}

Also, the buffers do not get recycled between glDrawElements calls.
What did you mean with this :

Another rough one was that in Android 1.5 putting an array into a
buffer using a non-zero offset into the array to start from doesn't
work. Works in later versions of Android, however.

I am not using multiplexed arrays, thus each array starts at index 0
(for color, vertices and texcoords). The data it self is absolutely
fine - I validated this in my PC version.

Is there any way to force that the GL interface on Android has
rendered all data provided during the OnDraw event of the render? How
bad/important are the clientstates (glEnableClientState) on Android?
Can I recycle the ByteBuffers every frame or should I have several
that get swapped each frame - I`ve read somewhere that GlSurfaceView
gets double-buffered - maybe I simply change the bytebuffers in an
OnDraw call where it gets used by a native render call?

On 13 Feb., 07:24, Lance Nanek lna...@gmail.com wrote:

I haven't run into anything like that myself. I do often run into
issues that can cause the data to be incorrectly offset or otherwise
messed up, however, which might look similar.

The position of the buffer is important when you call glVertexPointer,
for example. So if the way you filled the buffer changed the position,
it has to be rewound or otherwise set back to where you want it before
you call glVertexPointer.

Another rough one was that in Android 1.5 putting an array into a
buffer using a non-zero offset into the array to start from doesn't
work. Works in later versions of Android, however.

Another issue is that the way the glVertexPointer call works is that
it doesn't consume the actual data. It is just setting the pointer to
the data. So changing the data before your other calls actually cause
it be used later on would cause trouble.

Hi,

I got an issue while rendering a number of meshes on aGlSurfaceView

glVertexPointer(3, GL10.GL_FIXED, 0,

It looks a bit like the native interfaced get spammed by my render

It behaves completely the same on emulator and an actual phone. I am
using the rendering pipeline on a PC project as well were is works

I begun feeling really desperate and dumb because I can't get this

Re: [android-developers] Re: Multitouch seems badly broken on Nexus One 2.1-update1

So Robert.. is this a platform issue in your mind.. being that it happens on
all android devices currently regardless of manufacturer? Or is it a driver
issue for each hand set and just oddly happens to be coincidental that
various manufacturers have the exact same issue with multi-touch? I am sure
what Diane says is accurate... but yet it seems odd that different
manufacturers have the same problem.

On a slightly different note.. what is the stance of the Android platform
team as a whole towards game developers? By this I mean, if this is indeed
an issue on different manufacturer's handsets.. is it important enough that
game developers, which for sure will be a large segment of popularity for
android as it is on iPhone.. can get this escalated enough to get some
platform/driver developers looking into it and if possible, tap the
community (such as Robert) to help, so we can figure out exactly what is
going on? It just seems too crucial of an issue to overlook being that it
directly makes it impossible as of now for game developers to really utilize
multi touch.

Robert (et all)... an app I want to eventually get around doing is a drum
machine app.. with multiple drum pads. On the iPhone, an app called
BeatMaker allows for 5 pads at once to be touched. Would this issue possibly
make an app like this not work? I don't even know if Android can handle more
than two touches at once.. but there are plenty of apps out there that will
use more than two simultaneous touches at once.

A more capable multitouch screen probably costs more. If that is the
case, it isn't really surprising that multiple manufacturers would go
with a cheaper, less capable one.

Re: [android-developers] MapView Overlay that does always keeps an item selected?

2010-02-13 Thread Fabian Sturm

Hi,

wow thanks a lot, your guess was right, I was missing an invalidate.
Most of the time I would do an animateTo and that itself would trigger
an invalidate :-)

But unfortunately still not everything works.
There seems to be a problem with focus handling.
I can set the different items focus by taping on them or by calling
setFocus.
But if an item has focus, I then tap on an empty region so that the item
looses it's focus, you can neither set the focus by taping on it nor by
calling setFocus. The only thing that helps to get it out of this broken
state is if you tap on a different item and then on the original.

I traced it down and it seems that the correct item gets the focus set
internally. I can check this with getFocus. But during the getMarker
call you see the bitSet is wrongly 0.

So maybe this time it is a real bug in mapview?

Thanks a lot, Fabian

And sorry for those many posts :-(



Am Samstag, den 13.02.2010, 15:01 -0600 schrieb TreKing:
 Hmm ... it should, as the currently focused item should be drawn last
 (on top) by default. Maybe try invalidating the view after resetting
 the focus to force a redraw and see if that works?

[android-developers] Lazy Loading Images in a ListView - consensus approach?

2010-02-13 Thread Carmen Delessio

Here are 4 references that I have found for lazy-loading images into a
listview in Android.
The idea is to display a placeholder image, get the actual image in the
background, update the ImageView in the list when the image is available.

I've tried to do this in the simplest way possible using an AsyncTask in an
Adapter.
The outline of that approach is below.  Is it flawed?
Is there an agreed approach to handling this common task?

Re: [android-developers] Lazy Loading Images in a ListView - consensus approach?

2010-02-13 Thread Romain Guy

I haven't looked in details at the 3 other approaches but I know that
a big difference between what I do in Shelves and what I've seen done
in other places is how user interaction is handled. Shelves listens to
scroll events on the ListView and tries to identify taps vs scrolls vs
fling to always give priority to the UI. For instance, when you touch
the screen to stop a fling, Shelves starts loading images, but does so
only after a very short delay so that if you are touching the screen
to fling some more, the fling animation won't stutter because of the
extra work load. But that's details.

[android-developers] Re: Pinch-zooming on maps gives no feedback

2010-02-13 Thread JP

Correct.
I don't get any draw()'s in an Overlay during pinch-to-zoom action.
Once released, the map snaps to the next zoom level (as driven by the
MapView et al). This triggers draw()'s and the app has an opportunity
to catch up.
Can you confirm draw()'s are indeed fired during pinch-to-zoom, as
long as multiple locations are touched?

 Oh, wait, hang on, you're saying the draw()s AREN'T being dispatched
 in the Overlays during pinch-zoom?  Huh.  Well, if that's true, then
 that wouldn't work at all.  I'll have to test it later.

  As nothing is fired in the way of an Overlay - how would it know to do
  anything?

Ever since the update that allows multitouch gestures on the Maps app
(pinch-zooming, mostly), I've noticed that apps using the Google Maps
API also seem to automatically support it.  That, in and of itself, is
good.  Convenient!

However, my app has a need to know when the user has zoomed the map.
As it stands now, I've just been watching over the only way this has
been possible before: The zoom control buttons.  It appears that
there's no callback to know when the map has been zoomed (only
MapController commands to MAKE the map zoom), so developers don't
appear to have any way of knowing if the zoom level was changed
outside of their control (i.e. pinch-zooming) apart from constantly
polling the MapView.

Is there any good way around this, or is an update like this in the
cards for the API?  Or am I just missing something obvious?
