hi Nithin,
i also guess the same thing because of that what i did was i create a
very simple application. it also sends 2 sms's. this is really
frustration.

this the application

package com.sms;

import android.app.Activity;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.widget.Toast;

public class sms extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
sendSMS(772376937, Randika);
Toast.makeText(sms.this, SMS Sent,
Toast.LENGTH_LONG).show();
} catch (Exception e) {
// TODO Auto-generated catch block
Toast.makeText(sms.this, e.getMessage(),
Toast.LENGTH_LONG).show();
}

}

public void sendSMS(String number, String msg) throws Exception{
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(number, null, msg, null, null);
}
}

[android-developers] Re: ProgressDialog - how to remove the numbers

2010-05-10 Thread oriharel

relax bibek, I will explain...

since I don't know how to upload screenshots here, I'l do my best to
describe.

about the example - as I said, in the ApiDemos there is a progress
dialog example. look it up.

about the numbers - when the dialog shows, you see the orange progress
bar start running, and underneath it you see 2 sets of numbers:

25% 25/100

these are running numbers as the bar progresses.

I need these to be hidden (at least the 25/100).

  anyone?

[android-developers] How to set and get thread priority from Java and native layers

2010-05-10 Thread KK

I have a multithreaded streaming app which has mainly the following 5
threads

1 Main App(UI) Thread
1 controller thread (in native)
1 audio decoder thread (in native)
1 video decoder thread(in native)
1 thread to query the head position of audio (in Java)
 Apart from this I have video rendering with OpenGL.

My problem is, if I query the thread priority using the
Thread.getPriority method (my native threads make callbacks to Java
and I am making the query at that point of time), I am getting the
priority of each of them as 5. For my audio query thread (the last one
in the list) I am explicitly setting the priority using
Process.setThreadPriority(Process.THREAD_PRIORITY_URGENT_AUDIO);

Also for my decoder threads, I am giving higher priority than my
controller thread(using pthread APIs in native). But still finally all
of them seem to have same priority.

Can anyone please tell me what is wrong here. Also what should I be
doing to increase the priority of my threads(both from Java and
native).

Thanks
KK

You get AVRCP keys with the MEDIA_BUTTON Intent. But I don't know of

 The Gallery application most likely cannot be built using the SDK. Most

 This means what...is expecting to compile itself is: everything.

 You are welcome to attempt to make a port of the Gallery application
 that builds using just the SDK. You will need to find all unresolved
 imports, look at the code from the firmware that is missing, and
 determine if that is something you need to clone into your own project
 or if it is something you can just comment out (perhaps disabling some
 features).

[android-developers] Re: I've found a way to stop piracy of my apps

2010-05-10 Thread MobDev

 It took several days (almost a week) for crackers
to decompile Screebl Pro and find a way to circumvent AAL.  Typically
it takes about 90 secs from the time that we publish to the market for
the various warez sites to start tweeting the location of the
download.

I was wondering, after the first crack-run they obviously will have
devised a crack-method, which means that every other app using AAL
will be cracked within 90 seconds till a new version is released... A
week of cracking will only be the case during the first attempt...

[android-developers] Re: glTexImage2D very slow on phones like Nexus one

2010-05-10 Thread manjunath

Hi Robert,

Even I have a similar issue. The glTexSubImage2D API was taking long
time and sometime it was blocking ( in loadTexture() function ). So we
are creating a pixmap and then creatin a EGL Image of using
eglCreateImageKHR API and then calling glEGLImageTargetTexture2DOES
API .  I've also replaced the glTexImage2D API with this image
creation and creating texture from the image.

Though I'm able to see home screen, I see flickering effects when i
move from one window to other. and this also repeats in some
application like lunar lander.

Please let me know if creating EGLImage and creating texture everytime
the loadTexture function is causing these flickering effects.
Also if i induce a sleep for some 30ms before flipping, flickering
reduces.

Please help regarding this issue.


Thanks,
Manjunath

 Eong,

 All Mario and I are trying to say is that the thing you are trying to
 do (upload textures every frame) is generally not considered a good
 practice and workarounds usually exist that are more efficient,
 especially if you can target higher levels of opengl or use extensions
 like framebufferobjects.  If you would be willing to tell us something
 a little bit more specific about what you're doing that requires a
 texture update every frame, we could potentially offer some more
 efficient ways of doing it.

  Thanks, Mario.
  I think it's somewrong with the driver or the chip. It's not just a
  bandwidth problem. If it's really a bandwidth problem, it only has 1/7
  bandwidth of milestone? (150ms compare to 20ms with a full screen
  tex).That's very funny.

  I'm working on some libs, which will be used for our tools and games.
  When a full screen update only takes 20+ms, it's usable in some
  conditions as it already gets at least 40fps.

  On 4月17日, 下午6时22分, Mario Zechner badlogicga...@gmail.com wrote:

   It seems that the msm chips are notorious for having a low bandwidth.
   There's really no solution to that problem other than

   1) lowering your texture size
   2) lowering the bit depth of the texture, e.g. instead of using
   RGBA use RGBA444 or RGB565
   2) uploading your texture in patches, e.g. split it up into 4 smaller
   parts and upload one part each frame. This will probably lead to
  artifactsif your frame rate is low but could work otherwise.

   Just out of curiousity: why do you have to upload such a big texture
   each frame? If you'd state your scenario in detail we might be able to
   suggest other solutions to the problem.

[android-developers] Misleading incorrect runtime exception when missing resource

2010-05-10 Thread westmeadboy

This took me several hours to figure out so I thought its worth
reporting...

Manifest:

uses-sdk android:minSdkVersion=3 android:targetSdkVersion=4 /
supports-screens android:smallScreens=true
android:normalScreens=true android:largeScreens=true
android:anyDensity=true /

Resource strategy:

res/drawable
res/drawable-hdpi-v4

No problems when testing on a Nexus One, but on the HTC Hero got this
exception:

Uncaught handler: thread main exiting due to uncaught exception
...skipping...
Caused by: java.lang.reflect.InvocationTargetException
at android.widget.ImageButton.init(ImageButton.java:47)

392)

... 32 more

But its nothing to do with title_bar_shadow.9.png.

I guessed there was something corrupted somewhere and even went to the
extent of doing a factory rest on my Hero!

The problem turned out to be my own myicon.png which was present in
res/drawable-hdpi-v4 but not in res/drawable. I'd forgotten to put in
a smaller version in res/drawable.

I could have fixed this problem in seconds if the exception message
was something like:

Caused by: android.content.res.Resources$NotFoundException: File res/
drawable/myicon.png from drawable resource ID #0x7f020008

[android-developers] popupCharacters selection

2010-05-10 Thread Martins Mozeiko

Hi,

I am wondering if popup for key could select automatically popped up
character when implementing custom Keyboard with popupCharacters
property for key. I have keyboard layout that has only one popup
character for some keys and I would like to select it automatically
when I hold long press on normal key. That would significantly speed
up text input.

For example, I would like following scenario - I press key u, hold it,
then popup shows only one character ū that is automatically selected,
I release key u, and character ū is automatically entered in text
field.

Currently I must do following - I press key u, hold it, popup shows
only one character ū (not selected), I must release my finger from
touch screen, then press this ū character, release finger, and only
then it is entered to text field.

Thanks.

[android-developers] Re: ProgressDialog Problem with Rotation

2010-05-10 Thread Kumar Bibek

Well, first of all you need to understand what happens on change of
orientation.

1. The activity is killed.
2. The activity is re-started.

So, obviously, your progress dialog is no where when the activity is
restarted. Try to preserve the state of your activity while changing
orientation and on re-start initialize the dialog.

This is not very easy, you might have to try for yourself.

Thanks and Regards,
Kumar Bibek

How how I can make it?

Re: [android-developers] Add another Virtual Keyboard do simulate Control keys.

2010-05-10 Thread Rogério de Souza Moraes

Hi Mani,

take a look at the code of android-x86 that implaments a way to use MENU,
BACK and HOME buttons in a device with just touchscreen. The name of the
file that implements this is Touchable.java.

http://www.android-x86.org/documents/touch-only-device-howto

The inconvenient is that you need to do this modification in the
Androidplataform, but as you will use
Android to a specific device, if think it is not a big deal.

Hi folks,

I am working with an hardware that have just five buttons. But I have just
one button available to the following functions: home, back, search,
soft-back(menu). The hardware is for automotive use, so that is because he
doesn't have the common buttons of a cell phone.
So I am thinking about create a second virtual keyboard that is called by
this available button, to show these buttons that are missing on hardware.
I want to know if it is possible to do. If it is, what type of code should
I follow to create this extra virtual keyboard? I think a good start is to
look at the code of the current virtual keyboard.

Any suggest will be appreciated.

Thanks,

Rogerio

 Requirement: The Device doesn't going to have any hard keys. So we want

 If any one having the solution, please guide me to do it.

This should be handled at the firmware level. SDK applications should
neither know nor care how these buttons are implemented.

Your engineers working on the device firmware have access to the
[android-porting] Google Group to learn more about how to make this
work, or they can follow the work of the android-x86 project:

Don't use uses-library. Put the JAR in your libs/ directory (and, in
the case of Eclipse users, add it to your build path).

[android-developers] Question about contact management (register and lookUpKey)

2010-05-10 Thread jef

Hello I'm a newbie with manipulation of Contact API

I would create an application that saved a references to chosen
contacts and create nex contacts.

So I first think of contact id but i have read that it was a bad idea
and the lookupkey was here for that ! So I try to play with lookupKey
and i'm facing some little problems...

First :

I choose a contact to saved, I did it by getting it's lookUpKey : no
problem.
I try to access later to contact with it's lookUpKey : no problem.

I go to contact native application, I change the first name of the
choosen contact.
I go in my application an try to access to choosen contact with saved
lookUpKey : problem, the contact lookUpKey has changed because I
change the first name...

Is there a way to have a unique access to a contact ? Or I was imagine
to register to modification done on my contact ? How could I solve my
problem ?

Second :

I created a contact with this  code :


ContentValues values = new ContentValues();
Uri rawContactUri =
cr.insert(ContactsContract.RawContacts.CONTENT_URI, values);
long rawContactId = ContentUris.parseId(rawContactUri);

this.cur = this.cr.query(rawContactUri, new String[]
{ ContactsContract.RawContacts.CONTACT_ID }, null, null, null);
String id = null;
if (this.cur.moveToFirst()) {
id =
cur.getString(cur.getColumnIndex(ContactsContract.RawContacts.CONTACT_ID));
this.cur = this.cr.query(ContactsContract.Contacts.CONTENT_URI, null,
ContactsContract.Contacts._ID +  =  ?, new String[] { id }, null);
if (this.cur.moveToFirst()) {
Log.i(ContactAPI5, LookUpCreate :  +
cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY)));
} else {
Log.i(ContactAPI5, no contact created);
}
}


And for these code, the result of lookUpKey is always an empty string.
Why do I have an empty string ?


Best regards

I don't know if I understood your advice, but I tried some things like
that.

I tried to put new data into the intent (like a used flag) and
updating the intent with setIntent(updatedIntent). I also tried to
create an useless new intent and replace the application intent with
setIntent(newIntent). But every time that I go back to application the
very first intent is handled again with its original data and then the
dialog is shown.

I tried to put some state into my code too, but how could my application
know the difference between an intent that was sent for the first time
and an intent that is being sent again? It's my main problem.

Check out this thread from a bit over a week ago:

http://groups.google.com/group/android-developers/browse_thread/thread/d8ea68116c17002a/af9b99df2dd7e03e

Hi,

I tried to use the flags that were in that thread and they don't work. I'll
try to explain my problem again, more clearly:

1) I have a widget with 3 buttons that starts my activity, sending 3
different types of intents to the activity. Each one makes my application
start showing a dialog A, B or C.

2) I have a onResume() function that handles which intent was sent and shows
the right dialog.

3) If my activity is not running, onResume() is called after onCreate() and
the dialog A, B or C is shown.

4) If my activity is already running, onNewIntent() gets the new received
intent, onResume() is called and the dialog A, B or C is shown.

5) Here comes the problem: if I go to other application (browser, for
example) and go back to my application, the intent seems to be received
again, onResume() is called and the dialog A, B or C is shown. But they must
be shown *only* when the widget is clicked.

Any suggestion? I'm so tired of this problem that I can't think about any
new solution.

Thanks again,

Esdras

Re: [android-developers] Common code reuse

2010-05-10 Thread Max Gilead

As Mark said, resources are going to be an issue.

For code though there's a simple way which would allow you to edit the
shared code on the fly. Create a standard Android project and manually
remove Android nature from its .project file (it you do this from inside
Eclipse it'll all get automatically updated). With this change you'll be
able to treat it as a library and reference its code from other Android
projects.

Cheers,
Max

 You can compile the source code into a JAR and have the other projects
 incorporate that JAR file. However, resources are then a problem -- you
 can't use R.layout, R.id, R.string, or similar ways to identify those
 resources.

I am assuming there is more to the application than the three dialogs,
by virtue of: if I go to other application (browser, for example) and
go back to my application. This means, apparently, that you are trying
to use the same activity for at least four different things:

-- dialog A
-- dialog B
-- dialog C
-- whatever other functionality you go back to

Move your dialog A/B/C handling into an activity that finish()-es itself
when done, so that it is not in the user's BACK button history. If need
be, do that after calling startActivity() for the activity that does the
rest of your app. That way, your dialog-displaying activities cannot be
navigated to except by your widget.

[android-developers] MMS URI Structure

2010-05-10 Thread Daniel Wiedenheft

Inspired by a post by CJ a few months ago, and because I ran into the
same problem, I did a little (OK, a LOT) of poring through endless
screens of code, and finally made some headway on how MMS messages are
stored.  Although the documentation blatantly omits this (read:
unsupported, may change in the future, don't rely on it, danger Will
Robinson) the list of supported URIs for accessing the parts of MMSes
is pasted below directly from the MMSprovider.java file.  Each of
these is preceded by content://mms/, and the # sign means that you
put in a number (ID) to select a specific record.  I hope others will
find this to be the breakthrough that I found it to be!

Example: To find a certain MMS record whose ID is 326 in the Inbox,
use the URI content://mms/inbox/326
To return all addresses related to message ID 326, use content://mms/
326/addr

sURLMatcher.addURI(mms, null, MMS_ALL);
sURLMatcher.addURI(mms, #,  MMS_ALL_ID);
sURLMatcher.addURI(mms, inbox,  MMS_INBOX);
sURLMatcher.addURI(mms, inbox/#,MMS_INBOX_ID);
sURLMatcher.addURI(mms, sent,   MMS_SENT);
sURLMatcher.addURI(mms, sent/#, MMS_SENT_ID);
sURLMatcher.addURI(mms, drafts, MMS_DRAFTS);
sURLMatcher.addURI(mms, drafts/#,   MMS_DRAFTS_ID);
sURLMatcher.addURI(mms, outbox, MMS_OUTBOX);
sURLMatcher.addURI(mms, outbox/#,   MMS_OUTBOX_ID);
sURLMatcher.addURI(mms, part,   MMS_ALL_PART);
sURLMatcher.addURI(mms, #/part, MMS_MSG_PART);
sURLMatcher.addURI(mms, part/#, MMS_PART_ID);
sURLMatcher.addURI(mms, #/addr, MMS_MSG_ADDR);
sURLMatcher.addURI(mms, rate,   MMS_SENDING_RATE);
sURLMatcher.addURI(mms, report-status/#,  MMS_REPORT_STATUS);
sURLMatcher.addURI(mms, report-request/#, MMS_REPORT_REQUEST);

[android-developers] Wired crash with ActivityUnitTestCase and dimens.xml

2010-05-10 Thread T-Droid

Hi @all,

I wrote a test case with ActivityUnitTestCase which was working fine.

Now I added a dimensions file (dimens.xml) and using the values with a
style.xml.

Here some parts from the dimens.xml:

resources
  eat-comment/
  dimen name=my_height15dp/dimen
resources

Here the attrs.xml:
resources
  declare-styleable name=Theme
attr name=theHeight format=dimension /
  /declare-styleable
/resources

And here the style.xml:
resources
  style name=myStyle
item name=android:layout_height@dimen/my_height/item
item name=android:paddingLeft?theHeight/item
  /style
/resources

The style.xml is in the android manifest.

On the G1 and the emulator the code works fine. In the test case I'm
getting a crash.

05-10 15:03:48.658: INFO/TestRunner(748):
java.lang.UnsupportedOperationException: Can't convert to dimension:
type=0x2

From the call stack I can see that this line causes the crash:

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

this.setContentView(R.layout.my_layout);
   }

Any idea?

T-Droid

 Don't do that, use a StringBuilder and StringBuilder#append() instead.
 String concatenation like the way you are doing it slows things down
 and creates more objects.

[android-developers] Re: Problem in sending in SMS

2010-05-10 Thread Brion Emde

Another option is to use the built-in ACTION_SEND or its variants, so
that you are using the facilities that are already available. This is
and especially useful approach for a beginner.

Look for ACTION_SEND in this document:
http://developer.android.com/reference/android/content/Intent.html

and you can piece together how to use it.

As an example, this bit of code lets the user choose whether to send
the information as SMS or as an email.

private void sendData(String value) {
// We're going to send the data in two forms, as message text 
and as
an
// attachment
FileOutputStream fos;
if (value == null || !(mSendText.isChecked() ||
mSendFile.isChecked())) {
Toast.makeText(this, R.string.msg_nothing_to_send,
Toast.LENGTH_LONG).show();
return;
}
try {
fos = this.openFileOutput(data.csv, 
Context.MODE_WORLD_READABLE);
fos.write(value.getBytes());
fos.close();
Uri fileUri = 
Uri.fromFile(getFileStreamPath(data.csv));
// Log.d(TAG, File Uri:  + fileUri.toString());
Intent i = new Intent(Intent.ACTION_SEND);
i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

[android-developers] Communication between Activities in Tabs

2010-05-10 Thread Patrick

My application contains several Tabs. Each tab is it's own activity.
They are created by using for example Intent intent = new
Intent().setClass(this, SearchActivity.class); There I pass only the
class of the activity.
My question: how do I get the instance? (I want to invoke a method,
which hides some buttons in another tab, therefore I need the instance
of the activity). What is the best way to achieve this?

Thanks in advance for your help.

 automatic pairing does something that prevents later connection.  I
 wonder if once it is automatically paired without a pin, future
 attempts to connect recognize that it has been paired but doesn't
 recognize that no pin was ever requested and so fails for lack of a
 valid pin.  Just a guess.

2010-05-10 Thread Paul

I think if this thread gets enough response and attention then someone
from Google may notice. They've got to have people looking at these
posts once in a while.

Is there no official Bug list for Android Market? I did post a thread
here : 
http://www.google.com/support/forum/p/Android+Market/thread?tid=6bdc164d35206f39hl=en,
which claims its a Feature Request forum. Of course no responses
there yet.

For Android to continue to succeed they need strong support from the
Development community, how do we get heard?


 You can't actually make Google do anything, but it wouldn't surprise
 me if this is the sort of thing they have already thought long and
 hard about, but their many lawyers and bizdev types will have to
 completely grok the problem before anything is done.

[android-developers] Re: I've found a way to stop piracy of my apps

2010-05-10 Thread dadical

That argument assumes that I don't respond to those cracks with
improvements to AAL that will make it more difficult! :)  Also, each
app will need to be cracked individually, and I'm trying to work out
some ways to make that a job that isn't cookie-cutter.  The point here
is to get this past the pain threshold where it won't be worth the
trouble for an app that is only a few bucks.

This is fascinating stuff, but very, very non-lucrative.  I don't
really want to engage in this game, but I don't see an alternative
until it gets solved at the platform level.

Given the lack of commercial interest (and the prodding of several
smart devs), I've considered opening this up, but I'm not sure how to
do that without it simply lowering the barrier for pirates.

 I was wondering, after the first crack-run they obviously will have
 devised a crack-method, which means that every other app using AAL
 will be cracked within 90 seconds till a new version is released... A
 week of cracking will only be the case during the first attempt...

When i build/run application from within Eclipse, everything behaves
normal (that means all dividers are visible).
However, when i create/build/run new project by means of android

[android-developers] Namespaces and custom widgets

2010-05-10 Thread Edward Falk

As a continuation of the thread in
http://groups.google.com/group/android-developers/browse_thread/thread/390e8188cedd66a6,
I'm still trying to figure out how a custom widget can use
getIdentifier() to read attributes.

As an example, I have a widget class called CustomWidget.  It has
attributes inner_margin and outer_margin.  Normally, to read these
attributes, I would do the following in source code:

  import com.example.customactivity.R;// I don't want to do this.

  ...

  TypedArray a =
  ctx.obtainStyledAttributes(attrs, R.styleable.CustomWidget);

  innerMargin = a.getInt(R.styleable.CustomWidget_inner_margin, 0);


Because my CustomWidget is intended to be shared among a number of
projects, or even get published, it's a real problem having to import
R from whatever activity it's going to be linked with.

What I'd rather do is:

  int resid = ctx.getResources().getIdentifier(inner_margin, int,
  com.example.customwidget);
  innerMargin = a.getInt(resid, 0);

but getidentifier always returns zero.

Can anybody tell me the magic I need to perform to do what I want?

For completeness, my CustomWidget.xml file that defines the resources
looks like this:

?xml version=1.0 encoding=utf-8?
resources
  declare-styleable name=CustomWidget
attr name=outer_margin format=integer /
attr name=inner_margin format=integer /
 /declare-styleable
/resources

and for even more completeness, the entire source code can be found at
http://www.efalk.org/tmp/CustomWidget.tar.gz

[android-developers] Re: SIP Stack

i saw this in sipdroid project FAQ:

  Sipdroid now uses TCP for the signaling connection and keeps the

does anyone know how peer servers of sipdroid handle scalability when
there are a million of sipdroid clients connecting with the servers
using TCP?

as i observed, T-mobile Intermittently changes IP of my G1 phone
without any notice, which in fact tears down the TCP connection.

  Hi

  When I went through the document opencore_framework_capabilities.pdf
  I came to know that Android supports RTP streaming for 3gpp format.

  After doing a anaysis I found that the data from a server could be

  sent from the server are parsed by the Android device and sent to the
  decoder for playback.

  1. I want to know if it is possible that the PCM data captured from a
  camera and then encoded using a particular encoder could be streamed
  using  RTP from  android code i.e is RTP sender support present in the
  Android code ?. If not then can someone please mention what could be
  the possible modifications required.

  2. Does Android code support SIP stack ?.

  I assume that know that RTP is the actual media payloads, and that SIP
  is the rendezvous protocol to facilitate setting up the RTP listeners via
  an SDP announcement?

  That said, it sounds like you ought to look into RTSP if what you're trying
  to do is just stream. SIP is very, very complicated in comparison, and has
  all kinds of issues surrounding NAT's that are likely to just confuse the
  issue if all you're trying to do is Server-Client streaming.

i saw this in sipdroid project FAQ:

as i observed, T-mobile Intermittently changes IP of my G1 phone
without any notice, which in fact tears down the TCP connection.
   



Remember that SIP doesn't actually transport the media, that's
RTP which is over UDP. So losing the connection shouldn't generally
be any worse than losing a http connection generally.

As far as scalability, I woudn't worry about that too much. UDP
based SIP suffers from a lot of problems, not the least of which is
the lack of security (unless you manage to find DTLS or are running
it over IPsec). And of course NAT's are tricky as I mentioned before.

But I still haven't heard why RTSP wouldn't be a better choice if
this is just server-client streaming. SIP is a kitchen sink of a
protocol.

Hi
 
 

When I went through the document opencore_framework_capabilities.pdf
I came to know that Android supports RTP streaming for 3gpp format.
 
 

After doing a anaysis I found that the data from a server could be
streamed to the android device and played back. i.e the RTP payloads
sent from the server are parsed by the Android device and sent to the
decoder for playback.
 
 

1. I want to know if it is possible that the PCM data captured from a
camera and then encoded using a particular encoder could be streamed
using  RTP from  android code i.e is RTP sender support present in the
Android code ?. If not then can someone please mention what could be
the possible modifications required.
 
 

2. Does Android code support SIP stack ?.
 
 

I assume that know that RTP is the actual media payloads, and that SIP
is the rendezvous protocol to facilitate setting up the RTP listeners via
an SDP announcement?
   
 

That said, it sounds like you ought to look into RTSP if what you're trying
to do is just stream. SIP is very, very complicated in comparison, and has
all kinds of issues surrounding NAT's that are likely to just confuse the
issue if all you're trying to do is Server-Client streaming.

[android-developers] On activity (re)usage en creation

A question that might be a bit general/basic knowledge, but for me it
has a quite direct background, so i'll form it as an example:

I have an activity entry showing something equivalent of a blogpost,
that might have comments. You can click somewhere to open a comments
activity. But in this activity there are links back to entries,
creating a nice line of activities.

If I call the entry activity (with an intent) on a link to show this
entry, am I re-using the old activity, or am I creating an endless
string of entry, comment, entry, comment activities (pretty cost-
ineffective that would be).

You can test this pretty easily by doing what you described and backing out.
If it's the former, you should have 2 back presses. If it's the latter, you
should have to back out as many times as activities you started. Yes?

 How how I can make it?

[android-developers] Re: How can I know if OpenGl has drawn something?

2010-05-10 Thread Robert Green

What are you trying to do?

glReadPixels is a pipeline stall - it will slow everything down.  If
you want to check to see if an object has been touched, use a
collision detection system, unproject the touch point into a ray and
get the closest item that intersects with that ray.  It's actually
easier, more reliable and faster.

You probably won't be able to directly access other activities to bring them
to the front, though you could theoretically start those activities with the
proper intent.

All this begs the question of why you want to do this anyway?

[android-developers] Re: SIP Stack

2010-05-10 Thread HeHe

i was not thinking about media.

i guess the reason why sipdroid+TCP+pbxes can lower battery use is to
enlarge sip registration expiration, eg. to 5 minutes or longer. what
if mobile service provider changes phone IP earlier than 5 min when
the provider finds no traffic to/from the phone? it will not be able
to receive incoming calls without re-registration.

anyway, i am just guessing. do you know the usual (or by default)
registration expiration between sipdroid and pbxes?

Again, if this is just server-client streaming this is yet another
reason to avoid SIP and look at RTSP. SIP is a rendezvous protocol,
and all rendezvous protocols are complicated, with lots of things to
consider.

AFAIK -- it's been a long time -- SIP registrations can be very long
lasting. Unless something has actually changed -- like your IP address
moved -- it shouldn't be a problem. I'm not entirely convinced that this
is a huge issue anyway because the cellular guys are probably moving
you around at L2 for the most part (again, it's been a long time since I've
paid attention to the 3gpp guys), so IP address changes are probably
pretty rare. I have no idea if anybody's been deploying mobile IP which
would more directly solve this issue.

[android-developers] Re: On using themes?!

2010-05-10 Thread Mariano Kamp

Hmmh, also no answer to this question on themes. Maybe the answer cannot be
given with two lines? So let me explain what I would expect step by step and
you stop me were I deviate from the Golden Path? I'll try yes/no questions.

In the simplest terms I would expect that in every place I can specify a
color in RGB (#) I could also specify a symbolic name instead. This
should work like @color/xyz, but with one more level of indirection that
lets me switch between themes, like dark and light.

Is that possible?

I would expect those themes to be applicable to (a) widgets, (b) drawables
(see the mentioned example) and (c) when I need to style something myself
like HTML. Are (a) - (c) possible?

Furthermore I would expect that I could define style keys myself, but I got
the impression that only keys from the android namespace can be used? That
lead me to believe that you can't define abstract colors, but only styles
for specific attributes used in the widgets' implementations.

And again, if there is any meaningful documentation I would be happy to read
it. Just send me the link or name of the book.

(examplehttp://groups.google.com/group/android-developers/browse_thread/thread/5b4ce3e49a1b63d2/)

Let's say I have a drawable that I want to use as the background of a

android:shape=rectangle

I am aware of extending themes, but what do I put into the items? How do I
reference those new values then?

You probably won't be able to directly access other activities to bring

All this begs the question of why you want to do this anyway?

[android-developers] Re: On activity (re)usage en creation


 You can test this pretty easily by doing what you described and backing out.
 If it's the former, you should have 2 back presses. If it's the latter, you
 should have to back out as many times as activities you started. Yes?

Good point I think! That would mean that the back-button is defined as
go back 1 activity, and not something more fancy with states. I
couldn't find the precize definition of the back button, so i'll
assume you're right and go test. In the meanwhile, is there a standard
method to ensure some sort of singleton effect?
I'll check back later.

[android-developers] Re: How can I know if OpenGl has drawn something?

2010-05-10 Thread Alfonso

I've got that collision detection system implemented, yet. And I'm
agree to use glUnproject as the best achoice. My problem is that I
remap the modelview matrix with the sensors and when I rotate the
phone, change the coords of the screen returned by glUnproject. Even
if I keep the object in the same place of the screen. Furthermore, I
don't understand why it doesn't return values according to the given
viewport. Because of all this I was looking for alternatives, but if
you explain me what's the matter with glUnproject, I'll be really
pleasent.

Thanks you very much for this answer and (I hope) for the next one.

 What are you trying to do?

 glReadPixels is a pipeline stall - it will slow everything down.  If
 you want to check to see if an object has been touched, use a
 collision detection system, unproject the touch point into a ray and
 get the closest item that intersects with that ray.  It's actually
 easier, more reliable and faster.

 Not sure what you mean by singleton effect,

I was referring to the singleton pattern (http://en.wikipedia.org/wiki/
Singleton_pattern), but as its not completely correct in this case i
obfuscaded the term somewhat to singleton effect :) Sorry bout that.

 but you probably want to look
 at the launch mode flags when starting your activities. The singleTask flag,

I'll check that so i'll atleast have the choice between the two
options.

[android-developers] Re: ProgressDialog Problem with Rotation

2010-05-10 Thread Aaron

The solution is very simple, for anyone who runs into this in the
future...

As Kumar stated when the phone is rotated the activity is destroyed
and recreated - you don't have to play with Android for very long
before you realize that.

What I didn't know is you can override that behavior by adding this to
to the activity node in the android manifest:
android:configChanges=orientation

there is more information about it here:
http://groups.google.com/group/android-developers/browse_thread/thread/c2ff370c99317236/f955457847fc69b8#f955457847fc69b8

and

http://developer.android.com/reference/android/app/Activity.html#ConfigurationChanges

but basically instead of destroying the activity the method
onConfigurationChanged method is called.  I'm not sure what other
problems this creates but this seems to be better default behavior
than destroying and recreating everything

   I have a managed ProgressDialog that show the status as tasks are
   moving along.  The Activity.show is kicked off by an AsyncTask
   progressUpdates and the final Activity.closeDialog is called through
   the AsyncTask as well.  Everything works beautifully as long as the
   screen is not rotated...

   What am I doing wrong? I thought having the Activity manage my dialog
   would solve this for me... Here is the code I'm playing with:

   public class Enter extends Activity {
           ProgressDialog progressDialog;
           private final static int PROGRESS_DIALOG_ID = 1;

       @Override
       public void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.main);

           Button button = (Button)findViewById(R.id.progressbar_button);

           button.setOnClickListener(new View.OnClickListener(){

                           @SuppressWarnings(unchecked)
                           public void onClick(View v) {

                                   Enter.this.showDialog(PROGRESS_DIALOG_ID);
                                   new AsyncTask(){

                                           @Override
                                           protected Object 
   doInBackground(Object... params) {
                                                   progressDialog.setMax(30);
                                                   for (int a = 0; a  30; 
   a++){
                                                           
   publishProgress(new Integer((a+1)));
                                                           try {
                                                                   
   Thread.sleep(1000);
                                                                   
   Log.d(Enter, Click:  + a);
                                                           } catch 
   (InterruptedException e) {
                                                                   
   e.printStackTrace();
                                                           }

                                                   return null;

   onProgressUpdate(Object... values) {
                                                   
   super.onProgressUpdate(values);
                                                   Integer progress = 
   (Integer)values[0];
                                                   
   progressDialog.setProgress(progress.intValue());
                                           }

                                           @Override
                                           protected void
