 How can i get those values in activity from service without waiting

Option #1: Bind to the service, call some API method on the binder in
onServiceConnected(), unbind from the service, then call stopService()
in onServiceDisconnected()

Option #2: Call startService() with some custom action string to
indicate please send me the data along with a Messenger tied to your

Messenger, and call stopService() when the data arrives.

Option #3: Consider the data the service is generating to be part of
your data model and store it persistently, having the activity get the
latest data from the persistent store.

There are probably many more options, but those should get you started.

 One more question, In myactivity, i have handler which implements
 handlemessage(), is it possible to receive msg in it from service?

Use a Messenger.

[android-developers] TextSwitcher and/or TranslateAnimation changed in API level 8 and upwards?

2010-12-22 Thread Leif

I am using a TextSwitcher and a TranslateAnimation to create a
slotmachine reel effect.

It works fine on API levels 4 through 7, but on API levels 8 and 9 it
breaks down for some reason.

Any clues as to why this is happening?

The UI structure is like this:

FrameLayout-TextSwitcher-TextViews

Any known changes in TextSwitcher, TextView or TranslateAnimation
since API level 7?

Any pointers appreciated!

Regards,
Leif

[android-developers] TabHost not working in Froyo

Hi Everyone,

I have a TabHost in my app that works on my test device running
Android 2.1 (and all previous versions via the emulator).  However,
the tabs do not display when Running on Android 2.2 (Froyo) or later.
All there is is the content of the first tab and a blank spot where
the tabs should be.  Here is the code I'm using to create the TabHost:

TabHost

[android-developers] Re: Ant not building app properly

I would make sure you're running aapt as part of each and every build.
And also aidl, if you use aidl files. These both need to run *before*
you run javac, because they produce java files that need to be
compiled. If you run them after, you'll always be picking up the
version from your previous build instead of teh current one, and the
resource IDs won't match if you've made changes to the resources.

Also, make sure that your javac task lists as source directories both
your source, and the generated output from aapt and aidl.

This example is a bit outdated, but illustrates:
javac encoding=ascii target=1.5 debug=true extdirs=
destdir=${out.classes.absolute.dir}
bootclasspathref=android.target.classpath
verbose=${verbose} classpath=$
{extensible.classpath}
src path=${source.absolute.dir} /
src path=${gen.absolute.dir} /

 In this case, R.id.my_layout (or whatever I called it) would point to
 a non-existing resource. Of course, building this in Eclipse would not
 show these errors.

 2. The wrong string resources would be used in an unpredictable way.

 3. Layouts would not load up correctly, also causing random failures
 and force-closes.

 I believe that the source of these issues is related to how it is
 compiling R.java and the way it links it up to resources. I am
 unfamiliar as to how it builds resources into apps, so I am at a loss
 as to why this is occurring in the first place.

 The interesting thing is that if I make some change to the source
 code, and do another 'ant compile' or 'ant install', the problems in
 the previous build disappear and new resource issues pop up.

 After plenty of googling, I could not find anything describing
 something similar to this issue. I am concerned that potentially
 building via Ant might be exposing issues that I am not aware of, so
 besides using Ant, I just want to make sure.

 Is this a known issue? I just want to make sure before I attempt to
 reproduce the problem on a smaller scale.

 My development computer is:

 - Mac OS X 10.6.5
 - from java -version:

 java version 1.6.0_22
 Java(TM) SE Runtime Environment (build 1.6.0_22-b04-307-10M3261)
 Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03-307, mixed mode)

 I'm just using the default JVM for this.

[android-developers] Re: determine dimensiona of the screen in View's constructor?

2010-12-22 Thread Utumno

Yes, I mean onSizeChanged().

Hmm, no way? Even if I have android:screenOrientation=landscape in
my manifest ? This way screen dimensions will ( am I right? ) never
change,  and should be accessible anytime...

Currently I initialize part of my View in its constructor, than I have
to do all kinds of locks to somehow survive without a crash until I
get the onSizeChanged() message and can initialize the rest (which
depends on screen size ) and then I have to ignore subsequent
onSizeChanges() which, for some reason, still sometimes come ( even
though, of course, neither the physical screen size nor orientation
has actually changed ). For example, if I have my app on top, and
screen saver kicks in, and I awake the screen,  then my app gets shown
again and gets ( in my opinion, spurious ) onSizeChanged() message
which needs to be ignored.

Doing the above is feasible, but messy. It would be way more
convenient if I could simply figure out the screen dimensions in
View's constructor, construct everything and do not bother with
onSizeChanged  ( like I do in versions of said app for Symbian and
Blackberry )

Re: [android-developers] Re: determine dimensiona of the screen in View's constructor?

onSizeChanged, which gives the size of the view, is one thing.

But you keep saying *screen* dimensions, which is quite another.

If that's what you need, you can use DisplayMetrics:

http://developer.android.com/reference/android/util/DisplayMetrics.html

Check out widthPixels and heightPixels, which give screen size.

[android-developers] Re: Ant not building app properly

I should also point out that you can get the 'android' command to set
up ant build files for you, and this is probably a better idea than
doing it yourself.

I have been doing it myself, based on what the android command did,
because when I first did it, there were various serious flaws in how
it did it, including the hardwired use of the 'ascii' encoding (which
is just plain nuts, and is still the default, but can be overridden
now).  But at this point, I plan to replace my android-specific
portion with using theirs, and just handle the build management
(checkout, etc.) with a wrapper that calls theirs to do the actual
build.

See here for how to use the 'android' tool to set this up:

[android-developers] Re: determine dimensiona of the screen in View's constructor?

2010-12-22 Thread Utumno

Yes, I actually mean Screen dimensions - the view is fullscreen and
will always be. Will check out, thanks.

On Dec 22, 5:23 pm, Kostya Vasilyev kmans...@gmail.com wrote:
onSizeChanged, which gives the size of the view, is one thing.

But you keep saying *screen* dimensions, which is quite another.

If that's what you need, you can use DisplayMetrics:

http://developer.android.com/reference/android/util/DisplayMetrics.html

Check out widthPixels and heightPixels, which give screen size.

Hmm, no way? Even if I have android:screenOrientation=landscape in
my manifest ? This way screen dimensions will ( am I right? ) never
change, and should be accessible anytime...

Sorry, there is nothing earlier, that is the point where this has been
figured out.

Hello Android gurus,
I am aware that when screen dimensions change, I get a call to
onScreenChanged() and there I can figure out its dimensions, however
it would be much more convenient if I could figure this out earlier,
namely in my View's constructor.
Any tips?

[android-developers] resultCode in onActivityResult returns 0

Hi I have one activity which invoked another activity

roomIntent.putExtra(roomName,roomNM );
roomIntent.setClass(AddScheduler.this,RoomList.class);
startActivityForResult(roomIntent,Room_SELECT);

protected void start(Intent intent)
{
this.startActivityForResult(intent,Room_SELECT);
}

protected void onActivityResult(int requestCode, int resultCode,
Intent data)
{
System.out.println (requestCode);

switch(requestCode)
{
case Room_SELECT:

System.out.println (resultCode);  //here it 
returns 0
 if (resultCode == RESULT_OK)
{
...
//Because result code returns 0 therefore this if conditio does not
execute.
}
}

}

And here is my other activity which returns result.

public class RoomList extends ListActivity
{
super.onCreate(savedInstanceState);
Bundle extras = getIntent().getExtras();
if(extras !=null)
{
value = extras.getString(roomName);
sw = getSwitchNameArray(value);
}
setListAdapter(new ArrayAdapterString(this,
android.R.layout.simple_list_item_multiple_choice,
sw));
final ListView listView = getListView();
listView.setItemsCanFocus(true);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

listView.setOnItemClickListener(new ListView.OnItemClickListener() {

@Override
public void onItemClick(AdapterView? arg0, View arg1, 
int arg2,
long arg3)
{
// TODO Auto-generated method stub
System.out.println (User checked boxes);

if (listView.isItemChecked(arg2))
{
System.out.println 
(###+listView.getItemAtPosition(arg2));
room = (String) 
listView.getItemAtPosition(arg2);
selectedRooms.add(room);
System.out.println (Size 
is+selectedRooms.size());

}

else
{
String str = (String) 
listView.getItemAtPosition(arg2);
selectedRooms.remove(str);
System.out.println (Size 
is+selectedRooms.size());
}
}


});

@Override
protected void onPause()
{
super.onPause();

System.out.println (User click on back button);

mySwitches = new String[selectedRooms.size()];
selectedRooms.toArray(mySwitches);
int str = mySwitches.length;
System.out.println (!...@#!@#...@#+str);
Intent returnIntent = new Intent();
//returnIntent.putExtra(SelectedSwitches,selectedRooms);
returnIntent.putExtra(SelectedSwitches, str);
setResult(RESULT_OK,returnIntent);
System.out.println (Before calling finish);
finish();
System.out.println (After calling finish);
}

  public String[] getSwitchNameArray(String rn)
{
..returns string array
}

I think in resultCode I get 0 because I write
setResult(RESULT_OK,returnIntent);  inside onPause () method. Or there
is another problem? I had write that inside onPause bacause in this
activity I am calculating name of selected items. And I never knows
when user had finished selecting items. After writing code inside
onPause I know what item user had selected from list and I can pass
them to the calling activity.

I think better approach is to add one button means suppose user click
on save button then selected item will be sent to the calling
activity. Want your opinion? where should write code. If it doesn't
affect write inside onPause() then why I got 0 from resultCode.

Re: [android-developers] resultCode in onActivityResult returns 0

2010-12-22 Thread Kumar Bibek

YEah,

Why are you calling finish from onPause method?  It will finish you
application, even when you would not want it to.

Try this. On a specific event, set the result and just call finish. That
should do.

Re: [android-developers] How to disable back button..?


Starting with API level 5, you can override onBackPressed().

For previous API levels, use something like:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
// your code here
return true;
}
return super.onKeyDown(keyCode, event);
}

Whether this is a good idea is another question.

Also note that the user can still use the Home key to leave the activty, 
and you can't override that.

Re: [android-developers] Re: Prevent an Android Service from getting destroyed after an unbind

2010-12-22 Thread Kalyan Akella

Thank you jotobjects, Kostya  Streets of Boston for your replies. They were 
very helpful while fixing this problem. Here are the 2 important changes I 
made to get it working exactly the way I wanted:

1. Removed the SharedPreferences checks while calling startService() inside 
the activity A. It just calls *startService(intent)*  *bindService(intent, 
this, 0)* inside the *onCreate()* method.
2. Service S is now a plain *android.app.Service* with a handler thread (and 
looper) for doing web-service calls on location changed events (note that S 
is also a *LocationListener*).
3. Introduced a control on the UI which when clicked causes activity A to 
send a certain message to the service S. Subsequently, the service does some 
cleanup and calls *stopSelf()* and gracefully exits.

Thank you all once again for the help.
Sincere Regards,
Kalyan

[android-developers] UnsupportedOperationException: glGenFramebuffersOES

2010-12-22 Thread pedr0

Hi at all,

when I try to use the function glGenFramebuffersOES I meet an
UnsupportedOperationException, I am working with android 2.1 update 1
under a Samsung galaxy S.

These  function aren't supported on these platform or I am wrong
somethings?

This is my code (very simple):

public void onDrawFrame(GL10 gl10) {

GL11 gl= (GL11) gl10;

if(first_step == false){
// distruggo
GLES11Ext.glDeleteFramebuffersOES(1, viewFramebuffer);
GLES11Ext.glDeleteRenderbuffersOES(1, viewRenderbuffer);
}
 // creo
GLES11Ext.glGenFramebuffersOES(1,viewFramebuffer);
[...other stuff.]
}

Thanks a lot.

Your lesson then: do the research first.

But from other hand - even competing apps/games exists it still does not
mean much. If your game is better then you attract users anyway
(for example we releeased couple of apps that shared some features
with existing apps - now our apps outnumbered them even 10 times).
So finish your app and release.

Re: [android-developers] Re: Encoding/decoding problem


Sounds like you have your own server, and seems like bug is possibly there.

Modify your Android code to do both: write to the memory card *and* send 
to the server. Then compare the files you get on the phone and on the 
server.

You cannot have Android resources in a JAR. Use Android library

Re: [android-developers] Web Server

Sure. You need a Java-based Web server (iJetty, NanoHTTPD, etc.), or
possibly a C-based one you can attach to your app via the NDK. Bear in
mind that this will really only be useful on a WiFi LAN, since the
phone will not have a publicly routable Internet address in most (if
not all) cases.

[android-developers] Re: TextSwitcher and/or TranslateAnimation changed in API level 8 and upwards?

2010-12-22 Thread Leif

Digging a little deeper reveals that there seems to be a difference in
how the textviews are sized (i.e. the children of the TextSwitcher).
On API levels 4-7 the height is 2904 pixels, while on API levels 8 and
9 the height is only 58 pixels.

So, something seems to have happened in terms of how the views are
measured?
Would be very happy if someone from the Google team could comment on
this.

Leif

 Any known changes in TextSwitcher, TextView or TranslateAnimation

[android-developers] Re: Setting up development environment on windows 7

2010-12-22 Thread gcstang

Is your Windows 7 32 or 64bit?
Ensure you're using the Oracle JDK should be 1.6.0_23 32bit
Not sure installing 64bit will help much either way unless you have a
pretty beefy machine, so I would uninstall the 64bit JDK.
What path did you install the AndroidSDK to?
Did you setup your JAVA_HOME, CLASSPATH and PATH?

What version of Eclipse did you download and install? There are a few
different versions with different capabilities.
I personally use MyEclipse but Eclipse should work just as well.
When you go here http://www.eclipse.org/downloads/
You should pick :
32 bit
http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/helios/SR1/eclipse-java-helios-SR1-win32.zip

Android SDK : http://dl.google.com/android/installer_r08-windows.exe
Android Plugin (ensure you read the one on Helios) : How to
http://developer.android.com/sdk/eclipse-adt.html#installing

Uninstall your applications first to start with a clean system if you
prefer it might make it easier.

Install the JDK I prefer to install the JDK to c:\java (note no spaces
in path) and you don't have to change references later.
Install the Android SDK (also make sure no spaces in the path you
install it to)
Install Eclipse (ensure no spaces in path something like c:\eclipse)

Once you're this far you will need to start the Android SDK
application SDK Manager.exe, select Settings and checkmark Force
https... then select Available Packages and expand the URL in the
right window select what you need to develop on (i.e. version of the
SDK you want to work with) then once all is selected click on Install
Selected at a minimum you will want :
The version you select i.e. SDK Platform Android 2.2, API 8, revision
2
Documentation for that version
Samples for that version
Google API's for that version
Usb Driver package (latest one)
Market Licensing package (latest one)

Once it's all downloaded you can shutdown the program you opened and
go over to the Eclipse application to start development, you will need
to tell the plugin where the path to your Android SDK folder is in the
preferences but that should be all you need to get started.

Good luck

[android-developers] Re: Anybody seen a slowdown in sales?

2010-12-22 Thread Sam

Hi everyone

The slow down is not related to the market ranking, my app has not
moved market ranking. I have seen sales drop from 15-20 per day to 3-4
per day. The app actually had more publicity in december than any
month previously.

The obvious changes are the market app changes - has something in the
new layout reduced sales dramatically - well i am sure Google know -
or should be looking into it.

For example moving the buy button from the bottom to top of the app
screen? now it seems to stand out less, and if you scroll down reading
about the app you end up at a dead end - no buy button.

regards

Sam

[android-developers] Thread problems

2010-12-22 Thread Schoel

I have a function call from a large engine (which I can not change)
which asks the user whether to save or not. Before this function call
returns, I need an answer from the user whether to save.

There is, as far as I know, no way to start an activity (or show a

this (code is not complete but should be enough for understanding):

int queryUserSave()
{
   s_Semaphore.acquire();
   startActivity(QueryUserSaveActivity);
   s_Semaphore.acquire();
   s_Semaphore.release();
   return s_nQueryUserSaveResult;
}

void onQueryUserSaveResult(int aResult)
{
   s_nQueryDialingLineResult = aResult;
   s_Semaphore.release();
}


The problem is, on the second acquire, the program halts (as intended)
without spawning the QueryUserSaveActivity (not as intended). The idea
was that the QueryUserSaveActivity would be spawned and the second
acquire would block until onQueryUserSaveResult is called.
I've checked the thread id of the thread in which queryUserSave is
called and the thread id in which the QueryUserSaveActivity is started
(if I don't use any semaphores) and they are not the same. I thus
conclude that startActivity starts the activity in another thread (the
UI thread) and therefore shouldn't care about the second acquire call.
I also tried setting the startActivity in its own thread and start
that thread with the same result as above.
Do you have any ideas what I can do to solve this?

Appriciate any help,

[android-developers] Internal refresh of app

2010-12-22 Thread Leon Moreyn-Android Development

So I am working on an app that is memory intensive. Currently I can
only go back and forth 18 times before my cause a critical memory
crash. I have tried putting in onStop and onPause and releases onBack.
Instead of releasing Process and threads, is there a way to quietly
reset the app in memory without shutting the app down and completely
restarting live on the screen, ie not make it look like a reboot.

[android-developers] Re: Encoding/decoding problem

2010-12-22 Thread ZeeZo

Hi Kostya,
To be honest,i was waiting for your reply.I have seen a lot of your
replies here related to data sending on network.Actually,my scenario
is that i am making my HTC desire as server and my PC as client.I
start my camera on HTC desire and then gets frames in the form of
byte[] from on onPreviewFrame method.

Now after some processing on this byte[],i write that processed byte[]
on two streams.
1-On file stream to write that on my SD card as JPG image and it
creates very fine image.
2.I am sending  the same byte[] through TCP to my PC and writing that
byte array as JPG file.But it create a whole black image.When i open
both of these images,i mean one from sd card and one from my PC.Only
first 40 bytes are same and then rest are totally
different.Moreover,there is more data on JPG file which i have written
on sd card than the one that i received on my PC.

One other thing that i guess i must mention is that,if i read already
written image on my SD and send that image from my HTC desire to my PC
through TCP.It works just perfect.Thing is i dont want to write that
image before on my SD card and then send to my PC.I want to send that
image directly to mY PC.

Oh one more fact,If i do all the above process with by half of my
byte[](offcourse it will not create a valid image),then instead of
just 40 byte,the whole data is same at both end.I mean on  SD card and
on my PC.Yeah both are whole black but atleast they have same data.

Please help.i am just stuck into this.I can post my code here if you
want.

best regards,
ZZ

[android-developers] Re: rawQuery selection args?

go through this?.  You mean, you'd rather go through the process of
constructing SQL by hand, including handing all the quoting rules?

How about It makes your code smaller, easier to read, and more easily
inspected for correctness?

This is a bit of basic SQL usage best practice that unfortunately all
too many people ignore. It's of sufficient value and importance that,
were I in an environment which LACKED this sort of parameterization --
I would implement it before proceeding further.

If you are dynamically constructing a SQL query yourself, you are
ALMOST certainly doing something wrong. There are exceptions, but any
time you find yourself doing string concatenation to produce a SQL
query, it's worth stopping and seeing if you can use parameters, or
avoid the problem with modifications to the schema. The VAST majority
of cases I've found in other people's code, or in writing my own, have
been avoidable.

And in the cases where it's not been avoidable -- constructed join or
filter criteria, for example -- the actual data is still ALWAYS
supplied via a parameter, without exception.

There would be no such thing as a SQL injection hack were this rule
followed consistently.

[android-developers] Providing EXTRA_AUTHORITIES when showing the ACTION_ADD_ACCOUNTS in order to show restricted account types to the user.

2010-12-22 Thread Tejas

The description for EXTRA_AUTHORITIES in android.provider.Settings
says :

This can be passed as an extra field in an Activity Intent with one
or more syncable content provider's authorities as a String[]. This
field is used by some intents to alter the behavior of the called
activity.

Example: The ACTION_ADD_ACCOUNT intent restricts the account types
available based on the authority given.

I want to show only the Corporate account type (or the activesync) to
the user. I'm unable to find what String constants need to be passed
as EXTRA_AUTHORITIES for this.

Can anyone point me to account type strings ? Or, provide an example
of restrictively launching the add accounts page ?

[android-developers] icons graphics in android app

What is the common approach when using icons in an android app

Android offers these hdpi, ldpi and mdpi folders for images in
different resolutions. How good does this work for all different

Or is it more common to create the icons programmatically as
vectorgraphics? If yes: can you suggest any turorials regarding this
topic?

Re: [android-developers] icons graphics in android app

It works very well. Image resources are packaged as PNG files, lossless 
compression.


Some useful links:

http://developer.android.com/guide/practices/ui_guidelines/icon_design.html

http://developer.android.com/guide/practices/screens_support.html

http://developer.android.com/guide/topics/resources/drawable-resource.html#NinePatch

It shouldn't be necessary to create icons from code, as there are only 
several fixed pre-defined resolutions, and hence, icon sizes (when 
expressed in pixels).


However, I find it useful to use vector-based (as opposed to raster 
based) drawing tools in Photoshop when creating my [very limited] artwork.

[android-developers] InetAddress and the isReachable method

2010-12-22 Thread clarkbriancarl

Hello,

A few years ago, I developed a free server monitor (bMonitor) that has
ping, port, and http(s) monitor capabilities. It has required very
little maintenance to keep up with the rapidly evolving Android OS.

However, in the last several months I have noticed more and more users
are complaining that ping does not work for them. I think I have
finally tracked this down to the isReachable method of the InetAddress
class. It literally seems to work sometime and not others.

More research on the isReachable method revealed that it first tries
to use the ICMP ECHO request, and if that fails tries the much slower
TCP version of ECHO.

More recently, I have found that the only way I can get isReachable to
work is using the loopback address as the host. Every time I try to
ping an external host, it fails. I have even tried putting a very long
time out (greater than 1 min) as the input parameter.

_blnStatus = InetAddress.getByName(localhost).isReachable(2);


The above line of code has worked for as long as I can remember. It
now seems, it fails more often than not.

I have also read that ping requires root access. However, I have a
terminal emulator installed on my phone that is NOT rooted, and ping
does work from it.

So, I guess I have several questions.


1) Has anybody else been experiencing the same problem?

2) Has something changed in the API to cause this?

3) Is it possible to run ping from my application, or do I need to
implement a custom ping routine?


Thank you in advance for any help on this perplexing problem.

[android-developers] OOP objects + complex view

2010-12-22 Thread sisko

Hi guys,

I am developing an app that need to display information on the stock
of a store. Each activity will have upto 100 items.

My plan is to layout this information in a 10 * 10 grid. Each box in
the grid represents an item of stock. Each of these items will be
represented by an icon and a piece of text beneath the icon (the
name). I setup a new layout which has an ImageView and a TextView for
this. I called the layout Tab.xml

So, I need to know if it is possible to write a java class which will
use the Tab.xml as the layout.
Then I can programmatically create each java class item, setting the
image and text as I go along.

Can anyone please give me some direction about this?

Re: [android-developers] OOP objects + complex view


Sure, that's possible:

http://developer.android.com/reference/android/view/LayoutInflater.html#inflate(int, 
android.view.ViewGroup)


You'd also need a way to position these views. You could use a 
TableLayout, instantiating TableRows from code as needed, and adding 
inflated (as per the above link) layouts representing table cells to 
table rows.


Or you could just use a class that does that for you:

Re: [android-developers] Thread problems


Just to add my two cents:

You didn't include information on what s_Semaphore is, but I'm guessing 
it's from java.concurrent.


Although I'm not too familiar with this package, the docs say this:

http://download.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/Semaphore.html

Conceptually, a semaphore maintains a set of permits. Each acquire() 
blocks if necessary until a permit is available, and then takes it.


If you constructed the semaphore with 1 for permits, then what you 
are seeing is as designed - the semaphore will block on second acquire. 
It's not reentrant, the way synchronized blocks are (which can be owned 
multiple times by the same thread).


You can verify this with a simple test:


try {
Semaphore sem = new Semaphore(1);
Log.i(TAG, Semaphore constructed);
sem.acquire();
Log.i(TAG, Semaphore acquired once);
sem.acquire();
Log.i(TAG, Semaphore acquired again);
} catch (InterruptedException x) {
Log.e(TAG, Semaphore interrupted: , x);
}


The test above will block on second acquire, and that is correct 
behavior, since the semaphore's permit count is 1.


Compare this with synchronized keyword:


synchronized (this) {
Log.i(TAG, This is synchronized block 1);
synchronized (this) {
Log.i(TAG, This is synchronized block 2);
}
}


The above will execute both blocks.

A few ways to fix the problem:

- Use a CyclicBarrier instead of a Semaphore.

- Rewrite the code using only the language's built-in synchronization 
syntax:


int queryUserSave()
{
  // start the activity, then
synchronized(this) { wait();  }
return s_nQueryUserSaveResult;
}

void onQueryUserSaveResult(int aResult)
{
synchronized (this) {
  s_nQueryDialingLineResult = aResult;
  notify();
}
}

[android-developers] Bitmap Matrix Rotate

2010-12-22 Thread nirm

Hello,

I have a bitmap that i want it to rotate all the time.
This bitmap is placed in a SurfaceView.
My question is: Do i have to create the bitmap every time i want it to
rotate?

here is my code it is placed is the on draw method:

leftMatrix.setRotate(degrees++, coords.getX()+bitmap.getWidth()/2,
coords.getY());

graphic.setBitmap(Bitmap.createBitmap(bitmap, 0, 0,
bitmap.getWidth(), bitmap.getHeight(), leftMatrix, false));
canvas.drawBitmap(bitmap, coords.getX(), coords.getY(), null);

Kind Regards
Nir

Re: [android-developers] Thread problems

Oh, and one more thing: the activity not getting displayed likely has 
something to do with the thread going into a wait state right after you 
call startActivity.


Since the call to queryUserSave comes from background thread (as I 
understand from your email), you could use runOnUIThread() with a 
runnable that in turn calls startActivity, just to make sure that the 
flow of starting the activity is not blocked.

Correct.

Correct. Not only does the other activity run on the main application

being doing anything until after current callback returns.

 Do you have any ideas what I can do to solve this?

Ask the save/no-save question before doing whatever causes the large

perhaps handling the no-save scenario yourself (e.g., make a backup of
the data file first and roll it back later).

[android-developers] Re: OpenGL Problem with Sphere Texture Mapping

pedro,

your problem has nothing to do with android.  I think you may need a
3D refresher to solve it.  Normals are not UVs.  Your UVs will depend
on how you want to map, but the easiest way to do it is to map from
the sphere center out using angles, like this.  Since GL has 2D
texture coordinate 0,0 as upper left, you will want to define where
upper left is on your sphere.  I'd use straight up and center as a
unit vector, or (0, 0, 1) if z is up in your world.  If y is up, then
(0,1,0) will be 0,0 in UVs.

so starting with that, you can calculate the UV of any point by
getting the difference of angle of that starting angle and the new
point.  Remember that if they both come from the sphere center, you'll
have complete 2PI radian coverage on both axis... so naturally
dividing the resulting angle by 2PI will give you a UV number between
0 and 1.

The process is like this (assuming z=up)

For each point:
// for U just look at the sphere from overhead
U = (atan2(point.x - center.x, point.y - center.y) + PI) / (2PI)
hyp = distance(point, center);
V = ((point.z - center.z) / hyp) + 1) / 2

I believe that is correct and there will be a more elegant way to do
it but today my head is in 2D math world so I can't remember how to
dot it out.  The idea though is that for every point, you can
determine the angle needed for U by looking at the sphere from
overhead and just using an arctan of the xy differences (assuming
z=up) of the center to the point.  The resulting range is in radians (-
PI to PI) so you have to add PI to change it from 0 to 2PI and then
dividing by 2PI gives you 0 to 1.  Then for the V value, you can just
examine the height (z) of the point and in conjunction with its
distance from the center, you've got an opposite over hypotenuse which
is the same as the sine of the angle, which is what you want to get a
evenly distributed texture top to bottom.  The number will also be
ranged from -1 to 1 so you need to add 1 and divide it by 2 to get the
0 to 1 range.  The texture should touch in the corners and if you use
the right one, look seamless.

If any of my math is wrong, please correct it after debugging, but at
least this should get you going in the right direction.

Cheers

If you just want to disable the back button and do nothing, you can

@Override

 // Your code here, If you wish to write any, else no

Thats it !!!

[android-developers] Re: OpenGL Problem with Sphere Texture Mapping

Oh here is a faster method - http://www.mvps.org/directx/articles/spheremap.htm

For each point (Assuming Y=up):

3DVec normal = (sphereCenter - point).normalize();
float U = asin(normal.x)/PI + 0.5
float V = asin(normal.y)/PI + 0.5

for z=up:
float U = asin(normal.x)/PI + 0.5
float V = asin(normal.z)/PI + 0.5

But in your code example I don't know if you were calculating normals
correctly.  Your normal should be a vector pointing from the center of
your sphere out the vertex, which is done by subtracting and then
normalizing to make it a unit-vector.

[android-developers] Re: How do i multi select images in the Gallery and send there URL to my activity?

2010-12-22 Thread bruce

What you want is ACTION_SEND_MULTIPLE.  You will receive a set of
Uris.

Something like
if (Intent.ACTION_SEND_MULTIPLE.equals(action))
 Intent.hasExtra(Intent.EXTRA_STREAM)) {
ArrayListParcelable list =
intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
for (Parcelable p : list) {
   Uri uri = (Uri) p;
   /// do something with it.
   }
}
Just add android.intent.action.SEND_MULTIPLE to your manifest.

 Thanks for your reply
 Do you know any other way to do this?
 My Activity is dormant and awaken by the user selecting images.
 There has to be another way to do this right?

thread (which you are blocking)

Mark,

I don't believe this is the case.

In fact, Schoel wrote this in his original message:


I've checked the thread id of the thread in which queryUserSave is
called and the thread id in which the QueryUserSaveActivity is started
(if I don't use any semaphores) and they are not the same.


Since activity always run on the UI thread, the above implies that the 
original entry point into the code, queryUserSave, is called on a 
background thread.


A background thread, unlike the UI thread, can be blocked as necessary, 
using wait() or other means, until it's time for it continue.

  Seems to be that you have the same problem (e.g. BiMap is contained in
  com.google.common.collect).
  Guava is a superset of the Google Collections Library

[android-developers] Re: TabHost not working in Froyo

Shameless self bump

 Hi Everyone,

 I have a TabHost in my app that works on my test device running
 Android 2.1 (and all previous versions via the emulator).  However,
 the tabs do not display when Running on Android 2.2 (Froyo) or later.
 All there is is the content of the first tab and a blank spot where
 the tabs should be.  Here is the code I'm using to create the TabHost:

 TabHost
         xmlns:android=http://schemas.android.com/apk/res/android;
         android:id=@android:id/tabhost
         android:layout_height=wrap_content
         android:layout_width=wrap_content

         RelativeLayout
                 android:layout_height=fill_parent
                 android:layout_width=fill_parent
         
                 TabWidget
                         android:divider=#00
                         android:id=@android:id/tabs
                         android:layout_alignParentBottom=true
                         android:layout_height=wrap_content
                         android:layout_width=fill_parent
                 /
                 FrameLayout
                         android:id=@android:id/tabcontent
                         android:layout_above=@android:id/tabs
                         android:layout_height=fill_parent
                         android:layout_width=fill_parent
                 /
         /RelativeLayout
 /TabHost

 LogCat provides nothing.

 Any input would be greatly appreciated.  Thanks!

You can put whatever you like as overlay over camera surface view
(except another surface view )

See our android sample in javaocr project:

  Camera app and camera h/w are two different things. You may want
  to write your own app that uses camera hardware and add your
  own UI elements to it. You can't overlay existing app.

[android-developers] Re: Proguard problem after 2.3 update

2010-12-22 Thread mukgup

I am also getting problem with compiling the project with combination of 
linux (sdk updated r8), android-2.2, ant (1.8.1 ant -version says  compiled 
on April 30 2010 ) and proguard. 

The problem i am getting from ant script is: 

.../ant/main_rules.xml:430: Expecting class path separator ':' before 
'hands-free' in argument number 1

I checked all my paths and make sure all are clean. There is no problem with 
it. The strange thing is same build script and source code works perfectly 
fine in windows (sdk updated r8), android--2.2, ant (1.8.1) and proguard.  

I feel the android SDK r8 version for linux is not fully baked yet Or i 
might be missing some thing. I end up disabling proguard on linux for the 
time being.

Is there any one able to make this combination working on Linux ?

Thank!
