[android-developers] How to start the native Camera app in 1.0 SDK?
Hi, The MediaStore.ACTION_IMAGE_CAPTURE constant, which was used to start the native Camera application to capture an image, has been removed in the 1.0 SDK. Is there an alternative way to start the native Camera app to take a picture and return it to my calling Activity?

[android-developers] Re: Intercept incoming call
Is this the same for outgoing calls? They also cannot be interecepted in 1.0? If so, what is the purpose of ACTION_NEW_OUTGOING_CALL? this is from the documentation: It is perfectly acceptable for multiple receivers to process the outgoing call in turn: for example, a parental control application might verify that the user is authorized to place the call at that time, then a number-rewriting application might add an area code if one was not specified. For consistency, any receiver whose purpose is to prohibit phone calls should have a priority of 0, to ensure it will see the final phone number to be dialed. Any receiver whose purpose is to rewrite phone numbers to be called should have a positive priority. Negative priorities are reserved for the system for this broadcast; using them may cause problems. If i understand correctly, the outgoing call can be ended, and we can also get the dialed number from the Intent's info. Is this correct?

There could be a setting in Android that would allow the user to set the device to send all calls to voicemail if the the caller is not in the family contact list and it is between 11:00 PM and 7:00 AM. We have a checkbox to allow users to send all calls to voicemail from a given contact, so I don't see why this should be a problem.

[android-developers] Re: Receiving SMS Messages in 1.0?
Hi Justin,
Related to the problem of sending binary sms to port, I have changed
that parameter to null, and I send the data message using a port from
5554 emulator to 5556. This seems to work looking to the log
files.
The problem is that I am not able to receive the SMS data message in
the 5556 phone. So there must be something I am doing wrong.
In order to receive the SMS to port messege in 5556 I have created
a BroadcastReceiver listening to the
android.provider.Telephony.SMS_RECEIVED action.
I did not know how to declare the port that this receiver is listening
to...so I figured out that maybe it was declared using the port option
in the manifest..
receiver android:name=.ServerMessagesReceiver
intent-filter
action android:name=android.provider.Telephony.SMS_RECEIVED /
data android:port=16001/data
/intent-filter
/receiver
Is this the right way to declare the port that this SMS receiver is
listening to? I suppose the problem is there
Thanks in advance for the help
Cristina

Hi,
I do not know if it is the right way, but I have found a way to get
the message.
Here I include my code to get the SmsMessages. I hope it helps you
public class ServerMessagesReceiver extends BroadcastReceiver {
static final String ACTION =

public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION)) {

SmsMessage[pdusObj.length];
for (int i = 0; ipdusObj.length; i++) {
messages[i] = SmsMessage.createFromPdu
((byte[]) pdusObj[i]);
}

By the way, Does somebody know how to receive anSMSthat has been

The SMS_RECEIVED_ACTION string used to listen for incomingSMS
messages seems to have gone missing. It used to be available from the
android.provider.Telephony.Smspackage, which also seems to have
disappeared, so getMessagesFromIntent has gone too.
Previously, you could create a Broadcast Receiver to listen forSMS
messages using this code:
String incoming_SMS =
android.provider.Telephony.Sms.Intents.SMS_RECEIVED_ACTION;
public void onReceive(Context _context, Intent _intent) {
if (_intent.getAction().equals(incoming_SMS)) {
SmsManagersms= SmsManager.getDefault();
SmsMessage[] messages =
Sms.Intents.getMessagesFromIntent(_intent);
}
Is there still a way to do this?

[android-developers] Modifying data before passing it to a list
Hi,
I have an app that reads Contacts and displays them in a list. I
want to modify some of the data before passing it to the list. Is that
possible? Here is my applications OnCreate() method
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mCursor = getContentResolver().query(People.CONTENT_URI,
null, null, null, null);
startManagingCursor(mCursor);
ListAdapter adapter = new SimpleCursorAdapter(
this, // Context.
R.layout.localizer_row,
mCursor,
new String[] {People.NAME, People.NUMBER},
new int[] {R.id.text1, R.id.text2});
setListAdapter(adapter);
}
For instance I want to change the Phone number of each of the contacts
(e.g. prefix it with country code). Is that possible? If so, how?
I also want to add another column to the cursor. This column will have
data from another source (Eg. Contact Category, Photo etc.). Is that
possible? If so how?

In SDK 1.0 the LocationManager is always reporting the gps provider

You can't, per se.
You can call getLastKnownLocation() to return, well, the last known
location, but that may be null (if there have been no locations recorded
for the requested location provider) or stale (if the location provider
has been out of service for a while).
Or, call requestLocationUpdates() and take action when you get new
position fixes from the location provider.

[android-developers] Algorithm writen in C
Hello buddies!! I'm involved in a biometric project. I need to write an app for Android that must use an algorithm writen in C language. This C code is very complex and for this reason translating this code into java is not an option. The idea is to develop the main application in java code and this would call to the algorithm somehow, so the algorithm could return a value for the main app. I know there are some libs writen in C/C++ and I'm wondering if I could do so for my project, write my own lib and call it from the main app. But I don't know if it is possible, how to do it, how to compile my C code for Android and so on. To help the algorithm is writen in C and is compiled for Linux. Could anyone lead me through the darkness?

[android-developers] How do I modify data from the database before sending it to a list?
Hi,
I am accessing Contacts data and passing that into a list. I want

looks like.
public void onCreate(Bundle savedInstanceState) {

R.layout.two_item_row, mCursor,
new String[] {People.NAME, People.NUMBER},
new int[] {R.id.text1, R.id.text2});
setListAdapter(adapter);
}
Do I need to create m own CursorAdapter (maybe inherit from
SimpleCursorAdapter??) If so then what methods do I need to override?
I also want to add a column that has data from some other source. Is
there a way to do that?

[android-developers] Re: Connect to an online SQL database
IMHO, the conceptually correct way to do this is with a ContentProvider, which exposes a database-like interface and can behind the scenes access any datasource you wish (yes, it can go across the net). 'Just' marshal your requests into a web request and parse the response into something like a MatrixCursor that you return (for queries).

[android-developers] PreferenceActivity Refresh Problem
I have a PreferenceActivity inflated from xml. One of the preferences launches an intent which opens an activity that clears all the preferences and resets them to the default values. My problem is that when this restore defaults activity returns, the previous preference values still appear on the screen. If I exit the preference activity and then reopen it, the updated preference values appear. This seems like a refresh issue. Is there a way I can tell the PreferenceActivity to refresh its values?

[android-developers] Re: SAXParser reports diffeernt qName on SDK 0.9 from SDK 1.0
It's just #038;, or amp;
http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references#Predefined_entities_in_XML
The and the ; delimit the entity.
But Chris, your XML in your source example there can't have an
ampersand there like that. You need to be using the escape/encoding.
If everything in the chain supports UTF-8 you can use amp;, if not,
use the numerical entity version, #038;.
Again, this is a different topic than the differences in the parsing,
but every XML processor I have ever seen will blow up on a non-escaped
ampersand.
Characters (or code points in Unicode terminology) outside the simple
ASCII range 32-127 (#x20; to #x7F;) must either be encoded as multi-
byte UTF-8 sequences or using numerical entities. In environments that
do not natively support UTF-8 it is often easier to use numerical
entities
For example, the XML I am using is coming from Google Base - it is
UTF-8, but you STILL have to use the encoding to escape the special
chars:
?xml version='1.0' encoding='UTF-8'?

Charlie,
Yes, I think we are saying ALMOST the same thing. But, I don't think #038;
is the Escaped Ampersand. I think it's just the Ampersand, and that's why
it's causing the problem.
As I say, I'm not a Unicode expert, but I think the proper sequence for an
escaped ampersand would be : #038; #038; I think that's how an escaped
ampersand would look in UTF-8. The ampersand escaping the ampersand :). Or,
of course the amp;
Sorry, I can't try it right now, but I'm interested to know if it works.
When I have time, I'll build an app to check it.

Subject: [android-developers] Re: SAXParser reports diffeernt qName on SDK
0.9 from SDK 1.0
Hey Brad,
Just to be sure I tested it out and manually typed in amp; into the
source for the web service. I didn't expect this to work, because even
manually typing it in still leads to each character being encoded.
In the quote you provided it says they MUST be escaped using either
numeric character references UTF-8 (and all unicode) encoding
does just that :) The '' is number 38.
On the other hand, I also tested the bracket characters and . Both
cause the same issue as the character. Other brackets such as [ and
{ and ( do not cause issue.
So clearly this does have something to do with the SAXParser in
Android handling the special XML characters. I have never used
SAXParser outside of Android so I cannot say whether or not it is any
different. But I can confirm that this did not happen in 0.9 and I am
99% confident it should not be happening at all.
Thanks,
Chris

The other actually follows the format settings. The first question, however, is more difficult. The only specs I've been able to find on the 422 is that it's essentially 4 bytes of data with 2 pixels in it (equating to 6 rgb bytes. To decompress the data use the following algorithms. U = yuv[0] Y1 = yuv[1] V = yuv[2] Y2 = yuv[3] Then use equation to convert YUV to RGB is (remember to apply it to both Y1 and Y2): R = Y + 1.140V G = y - (0.395 * U) - (0.581 * V) B = Y + (2.032 * U) That, as far as I know, should get you a perfectly usable RGB picture out of it. Some notes about the emulator: It seems when you take a picture, it returns a picture that actually has many versions of the picture within it. Not sure why this happens, probably due to the video of the capture being lower res than the preview pane, thereby making the preview larger than the rendered video and the system seems to map it over. Not sure on this, but it *SHOULD* be all better when we run it on hardware. Unfortunately, no way to be sure on this until Oct 22. Now, I may be wrong on any of this, unfortunately I haven't completely tested it.

[android-developers] Re: ImageButton caching images when using Uri
Sorry to talk t myself on this thread, but in case anyone else runs

I'm seeing some caching problems when using anImageButtonwith a Uri

I'm using the button to add an icon to an item in one of my

(which I don't think the source is available for). I'm using the CROP
trick seen in this
application:http://code.google.com/p/apps-for-android/source/browse/trunk/Photost...
Specifically, I'm calling the image picker and then the crop like so:
protected OnClickListener cmdIconListener = new OnClickListener() {
// @Override
public void onClick(View arg0) {
Intent i = new
Intent(android.intent.action.GET_CONTENT);
i.setType(image/*);
startActivityForResult(i, AddTea.ADD_ICON);
}
};

Intent data){
// See which child activity is calling us back.
switch (requestCode) {
case AddTea.ADD_ICON:
// This is the standard resultCode that is sent back if the
// activity crashed or didn't doesn't supply an explicit
result.
if (resultCode != RESULT_CANCELED){
Intent i = new Intent(com.android.camera.action.CROP);
i.setClassName(com.android.camera,
com.android.camera.CropImage);
i.setData(data.getData());
Log.d(TAG, path: + data.getData().getPath());
i.putExtra(noFaceDetection, true);
i.putExtra(outputX, iconWidth);
i.putExtra(outputY, iconHeight);
i.putExtra(aspectX, iconWidth);
i.putExtra(aspectY, iconHeight);
i.putExtra(scale, true);
if(iconUri == null){
ContentValues values = new ContentValues();
values.put(android.provider.MediaStore.Images.Media.TITLE, name +
Icon);
values.put(android.provider.MediaStore.Images.Media.BUCKET_ID,
STeaP_Tea_Timer_Icons);
values.put(android.provider.MediaStore.Images.Media.BUCKET_DISPLAY_NAME,
STeaP Tea Timer Icons);
iconUri =
getContentResolver().insert(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
values).toString();
}
i.putExtra(output, Uri.parse(iconUri));
startActivityForResult(i, CROP_ICON);
}
break;
case AddTea.CROP_ICON:
if (resultCode != RESULT_CANCELED){
Log.d(TAG, Data String: + iconUri);
showIconButton(iconUri);
}
default:
break;
}
}
protected void showIconButton(String iconUri){
if(iconUri != null){
ImageButtoniconField = (ImageButton)
findViewById(R.id.iconButton);
Log.d(TAG, iconUri: + iconUri);
iconField.setImageURI(Uri.parse(iconUri));
iconField.invalidate();
}
}
So if the item doesn't have an icon, set one in the ContentProvider
and save the iconUri. If it does, just overwrite it with the new
cropped image.
This works fine if the item never had an icon. It shows in
theImageButtonwhen the Activity returns. However, if the item already
had an icon, my Activity still shows the old icon, even though it was
overwritten. It seems that if theImageButtongets the same Uri back,
even if I wrote a new image to it, it doesn't redraw, even if I tell
it to invalidate(). If I relaunch my Activity, the new image shows up
just like I expected. Funny enough, the Pictures application doesn't
see any images I created until I restart the emulator, which also
doesn't seem ideal!
So, is there anyway to handle this caching of the Uri? I seems like
the ContentProvider should be doing this when I write a new image to
it, but it doesn't seem to be. Also, before anyone suggests, I tried
deleteing the entry in the ContentProvider and making a new one and
that seems to partially work. It partilly works because, if the Uri
we get back it new, the view does refresh with this new Uri. However,

[android-developers] Re: PreferenceActivity Refresh Problem
I have an ugly solution to this.There should be somewhere to force it to
reload the preferences and refresh the screen, but just like you I do not
know how to do it. (Suggestions?)
However, what you can do is to finish the current preferences activity and
to restart it in a new activity, like so:
protected void resetPreferences(){
prefs = getSharedPreferences(..., Context.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
... // do all the resetting
editor.commit();
finish();
ComponentName comp = new ComponentName(this.getPackageName(),
getClass().getName());
startActivity(new Intent().setComponent(comp));
}
This at least works if you are on the main screen of the activity.
Yes, it is a hack.

2008/10/2 Amos [EMAIL PROTECTED]
I have a PreferenceActivity inflated from xml. One of the preferences
launches an intent which opens an activity that clears all the
preferences and resets them to the default values.
My problem is that when this restore defaults activity returns, and
I navigate to another preference screen with, say, a checkbox
preference, the previous preference values still appear on the screen.
If I exit the preference activity and then reopen it, the updated
preference values appear.
This seems like a refresh issue. Is there a way I can tell the
PreferenceActivity to refresh its values? (I made sure I am comitting
all my preference changes)

[android-developers] Re: Obfuscation in eclipse for Android?
Hi Peli, blindfold:
I know it's been a while, but after having put the whole obfuscation
task on the back burner, I decided to come back to it yesterday, and I
just now, with tips from both of you, I have completed setting up an
Ant build script, using ProGuard, that obfuscates my class names very
nicely, and I'd like to thank you both very much for your helpful
comments!
For those still seeking help, I'll just paste the part of my Ant build
script that calls ProGuard, which was partly inspired by the ant build
found here:
http://code.google.com/p/zxing/source/browse/trunk/android-m3/build.xml?r=321
target name=optimize depends=compile
jar basedir=${outdir-classes} destfile=temp.jar/
java jar=${WTK-home}/proguard.jar fork=true
failonerror=true
jvmarg value=-Dmaximum.inlined.code.length=32/
arg value=-injars temp.jar/
arg value=-outjars optimized.jar/
arg value=-libraryjars ${android-jar}/
arg value=-dontpreverify/
arg value=-dontoptimize/
arg value=-dontusemixedcaseclassnames/
arg value=-repackageclasses ''/
arg value=-allowaccessmodification/
arg value=-keep public class

zackcorp.android.SyncingView/
arg value=-keep public class
zackcorp.android.ListView/
arg value=-optimizationpasses 1/
arg value=-verbose/
/java
delete file=temp.jar/
delete dir=${outdir-classes}/
mkdir dir=${outdir-classes}/
unzip src=optimized.jar dest=${outdir-classes}/
delete file=optimized.jar/
/target
This target goes after the compile target, and before the dex target.
I think I was finding that -dontpreverify really didn't make much
difference in the end, but -dontoptimize was needed, and -
dontusemixedcaseclassnames is DEFINITELY a must for building on
Windows, if you have a lot of java files (good call, blindfold!)
Also, as peli pointed out, I put all my AndroidManifest listed classes
- FirstView, SyncingView, and ListView - in -keep calls, to be
excluded from obfuscation and this is what made it work.
So I hope this helps other people out, it's not an easy road to
travel!

[android-developers] Re: SAXParser reports diffeernt qName on SDK 0.9 from SDK 1.0
Hey Charlie and Brad, Good news! I now have the ampersand being parsed correctly. However the change needed wasn't what we expected. Every time I changed the raw text in the database from the '' character to the escaped 'amp;' or '#038;' it didn't work, it would still break at that first ampersand. After doing some more research, I came across this: http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JAXPSAX3.html In that document, it says: Note: To be strictly accurate, the character handler should scan the buffer for ampersand characters ();and left-angle bracket characters () and replace them with the strings amp; or lt;, as appropriate. You'll find out more about that kind of processing when we discuss entity references in Displaying Special Characters and CDATA. I was working on implementing that, when I read further about CDATA sections. I decided to try this, by implementing the XmlDocument.CreateCDataSection method instead of the XmlDocument.CreateTextNode method I'm currently using in my .Net web service. Without having to modify my SAXParser code at all it worked with the new CDATA section! So what did I learn: 1. The SAXParser does indeed break like this by design. 2. Android beta's apparently did not implement a properly spec'ed SAXParser. 3. The SAXParser may be lightweight, but it comes at the cost of parsing robustness. For instance, the built in .Net parser does not have this issue. It simply reads the node, then everything after the node until it reaches an end node. It's smart enough to detect full nodes on their own, without simply assuming anything after '' is a new node like SAX does. Going forward, I'm going to keep using CDATA sections, and look to replace the parser if needed in the future. As a developer, I'm really disappointed a Google rep didn't chime in on this conversation. I'm used to having everything posted at forums.asp.net read by Microsoft devs. But I appreciate all the help of fellow community members like yourselves! -chris On Oct 2, 7:24 am, Charlie Collins [EMAIL PROTECTED] wrote: It's just #038;, or amp; http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_re...

If everything in the chain supports UTF-8 you can use amp;, if not, use the numerical entity version, #038;. Again, this is a different topic than the differences in the parsing, but every XML processor I have ever seen will blow up on a non-escaped ampersand. Characters (or code points in Unicode terminology) outside the simple ASCII range 32-127 (#x20; to #x7F;) must either be encoded as multi- byte UTF-8 sequences or using numerical entities. In environments that do not natively support UTF-8 it is often easier to use numerical entities For example, the XML I am using is coming from Google Base - it is UTF-8, but you STILL have to use the encoding to escape the special chars: ?xml version='1.0' encoding='UTF-8'? feed xmlns='http://www.w3.org/2005/Atom'xmlns:openSearch='http:// a9.com/-/spec/opensearchrss/1.0/' xmlns:gm='http://base.google.com/ns-metadata/1.0'xmlns:g='http:// base.google.com/ns/1.0' xmlns:batch='http://schemas.google.com/gdata/batch' idhttp://www.google.com/base/feeds/snippets /id updated2008-09-29T18:18:13.843Z/updated title type='text'Items matching query: ([review type:restaurant][location:Atlanta, GA]) [item type == reviews] /title link rel='alternate' type='text/html' href='http://base.google.com'/ link rel='http://schemas.google.com/g/2005#feed'type='application/ atom+xml' href='http://www.google.com/base/feeds/snippets'/ link rel='http://schemas.google.com/g/2005#batch'type='application/ atom+xml' href='http://www.google.com/base/feeds/snippets/batch'/ link rel='self' type='application/atom+xml' href='http://www.google.com/base/feeds/snippets/-/reviews?start- index=1amp;max-results=8amp;bq=%5Breview+type%3Arestaurant%5D %5Blocation%3AAtlanta%2C+GA%5D' / link rel='next' type='application/atom+xml' href='http://www.google.com/base/feeds/snippets/-/reviews?start- index=9amp;max-results=8amp;bq=%5Breview+type%3Arestaurant%5D %5Blocation%3AAtlanta%2C+GA%5D' / author nameGoogle Inc./name email[EMAIL PROTECTED]/email /author generator version='1.0' uri='http://base.google.com'GoogleBase/ generator openSearch:totalResults199/openSearch:totalResults openSearch:startIndex1/openSearch:startIndex openSearch:itemsPerPage8/openSearch:itemsPerPage entry . . . . .

My code is:

This code works fine when I performed this task alone in another

If you subclass from ResourceCursorAdapter you should only have to
implement bindView(), where you copy the data from the Cursor to the
views in the list item. See
http://code.google.com/android/reference/android/widget/CursorAdapter.html#bindView(android.view.View,%20android.content.Context,%20android.database.Cursor).

[android-developers] Re: call WebService
If you search this forum you find a lot of info on this topic. It depends what you mean by webservice, but if you mean SOAP over HTTP, the typical path is to use kSOAP on Android. Anddev.org has some good samples, including a kSOAP one: http://www.anddev.org/webservice_soap_with_complex_data_type_and_ksoap_client-t2195.html. Though, I would also still argue that you should not use SOAP on a small embedded platform device like a mobile phone. I know, I know, relax - people do it all the time, and many people disagree - I realize that. But still the stuff that makes SOAP useful, transactions, types, orchestration, etc, are all overkill in my opinion on an embedded device. You can avoid all that overhead (and even the envelope), and STILL use your existing SOAP service, by making a SOAP proxy using something that takes more of a plain HTTP and XML appoach (POX), or even REST, and have that proxy make the required SOAP calls. Put all the SOAP horsepower on the server, if you have to use SOAP, and make the Android client ultra simple via some kind of a proxy.

[android-developers] Socket HttpURLConnection don't work?
thanks for the response. i'd previously checked the samples included with the SDK for network code and found none. but then it occurred to me to check the manifest anyway for correct permissions syntax. sure enough, i had the uses-permissions inside application when it should have been inside manifest. ideally the DTD etc would have caught this, but at least i have the solution. now on to the next problem... :-] thanks again, j If you are seeing java.net.SocketException : unknown error when trying to use the network in Android it is probably the permissions. I know you have read this thread and you say you have the permission there, but I would triple check it and make sure it's correct. I was getting this error message in a bunch of apps that were written pre 0.9/1.0 and as soon as I added the permission to them they started working again (the networking that is, I also had to make the other non network related API changes of course - but that stuff is unrelated to this message/issue). I was confounded by this error message for a while too, checking over my code that I knew worked from before, debugging, etc - really vague, unhelpful, that should be improved, but the network DOES work as expected once you have the proper permission.

[android-developers] OpenGL ES documentation/tutorial suggestions
The documentation for OpenGL ES inside of Android is obviously lacking -- it's completely void of any text. Now, this is apparently not that big of a deal as it's essentially a clone of J2ME's OpenGL ES, however, I've never used that and am wondering what's a good way to get started in learning it? I've seen the Android-GL tutorials and read all the Android-specific information I can find. But I feel I'd benefit most from a thorough documentation of the functions so that I can get an idea of how to do it. I've tried finding outside documentation but it all seems a tad lacking. What would you suggest in documentation/books/tutorials in learning the OpenGL ES used by Android? I'm not afraid of technical information, but I would like a general tutorial on basic infrastructure and design in addition. Finally, are there any questions or information that you think would be useful in learning OpenGL even if it's not directly related. I'm interested in all of it, from planning the design to optimizing.

opinion on an embedded device. You can avoid all that overhead (and
even the envelope), and STILL use your existing SOAP service, by
making a SOAP proxy using something that takes more of a plain HTTP
and XML appoach (POX), or even REST, and have that proxy make the
required SOAP calls. Put all the SOAP horsepower on the server, if you
have to use SOAP, and make the Android client ultra simple via some
kind of a proxy.

[android-developers] Rotating an image using Drawable
i don't know whether this is what you're looking for, but Lunar Lander has an example of drawing a rotated Drawable. hth create image using the bitmap then use the Matrix and its preScle func.. and paasing this as a parameter u can create another bitmap.. like createBitmap(image,0,0,imahewidth,height,matrix,false) based on the prescale value it will give the transformed image --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: specs for YCbCr_422_SP pixel format
On Oct 2, 11:49 pm, Nikkelitous [EMAIL PROTECTED] wrote: The second question you asked is relatively easy. There are two because one of them will return raw data ignoring the format (Uncompressed data direct from the camera). The other actually follows the format settings. that's what i thought but the raw callback returned null, with or without setting picture format to YCbCr_422_SP. The first question, however, is more difficult. The only specs I've been able to find on the 422 is that it's essentially 4 bytes of data with 2 pixels in it (equating to 6 rgb bytes. To decompress the data use the following algorithms. U = yuv[0] Y1 = yuv[1] V = yuv[2] Y2 = yuv[3] yes, this is what i used to decode the raw data. Then use equation to convert YUV to RGB is (remember to apply it to both Y1 and Y2): R = Y + 1.140V G = y - (0.395 * U) - (0.581 * V) B = Y + (2.032 * U) That, as far as I know, should get you a perfectly usable RGB picture out of it. Some notes about the emulator: It seems when you take a picture, it returns a picture that actually has many versions of the picture within it. Not sure why this happens, probably due to the video of the capture being lower res than the preview pane, thereby making the preview larger than the rendered video and the system seems to map it over. Not sure on this, but it *SHOULD* be all better when we run it on hardware. Unfortunately, no way to be sure on this until Oct 22. this is what i got as well. well, let's hope the real thing can take picture properly. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How many threads can be created or how to avoid thread leak
HI,
I am developing a chat application. Everytime a user clicks a button a
thread needs to handle it as text message needs to be sent over
network. so, I am creating a new thread each time when the user clicks
on button. I wish only 1 thread handles all the messages to be sent.
But, resume/suspend/stop are all deprecated.
is there a way to do it.
currently, I am doing it like the following.
code
View.OnClickListener showChat = new View.OnClickListener() {
@Override
public void onClick(View v) {
t_send = new Thread() {
public void run() {
recv = false;
m_mychat = doExpensiveSend();
mHandler2.post(mUpdateResults2);
}
};
t_send.start();
}
};
/code

[android-developers] Re: onCreateOptionsMenu not called
Are you overriding either onCreatePanelView or onCreatePanelMenu? If so, try commenting that out and seeing the behavior. jason On Fri, Sep 26, 2008 at 12:33 PM, Teo [EMAIL PROTECTED] wrote: I just tried with the same project on another computer where i installed SDK 1.0 clean, same behavior...

That should be called on every menu button press; onCreateOptionsMenu() will only get called on the first menu button press. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 1.2 Published! -- Teo (a.k.a.

[android-developers] Re: OpenGL ES documentation/tutorial suggestions
I would recommend the book Mobile 3D Graphics with OpenGL ES and M3G by Karri Pulli and others. You may not be interested in the M3G stuff but the book is worth it for the introductory 3D and OpenGL ES coverage. This book was also recommended by the developer of the Oolong 3D engine for the iPhone which is based on OpenGL ES. You should also check out the AndroidGlobalTime and SpriteText examples under the Apps For Android project. These are full of useful code. Once the devices are released I expect there will be more information forthcoming such as which bits of OpenGL ES 1.1 are supported as well as recommendations for best performance. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
