   Sure, that's possible - as long as the server is accessible from the

The easiest case is that both phones are connected to the same Wifi router.

If the server is behind any NATs (looking from the client's side), the
client won't be able to get a connection.

Hi,
I am new to developing applications for android but have developed my
first app. I have following questions.
1. Is it possible to create a client server app? I mean the
application on one phone acting as server and applications on other
phones sending/receiving data from it?
2. Create a wifi network (may be using bluetooth) for the above client
server app. The idea being not to use the mobile service provide
network but rather a local network.
Thanks.
Kind Regards,
Ambi.

[android-developers] Re: Cupcake(API3) friendly way to pause/stop sound loops in SoundPool? Any ideas?

2010-09-22 Thread Clankrieger

While this thread is rather old, I have a similar issue - while using
the soundpool with the correct streamIDs.

There is a looping sound being started, remembering its stream id. But
when I try to stop it like this:

SoundPool.stop(mId);

nothing happens... the sound simply keeps looping. This happens on
API3, API4 and API7... The only way to stop the sounds is by releasing
the soundpool instance - but this way, I have to reload all pre-cached
data again.

 The streamID(int) is obtained when you play the sound:

 float, float, int, int, float)

 Returns non-zero streamID if successful, zero if failed

 Retain this streamID in your reference the sound, then you can pause
 it using the pause/resume methods.

 Personally I create a wrapper object (I call a Sound) which exposes
 simple methods like play(), pause(),stop() etc and the internals of
 streamID etc are handled in this class.  That way I can swap between
 using theSoundPooland MediaPlayer but still have the same Sound
 class exposed to the app.

2010-09-22 Thread Jason

There must be something crufty in your code.  I am doing this
currently in my game and it is working on all API versions (3+).

Post your code (both the play code and the stop code).

This is what I do (summarized):

SoundPool pool = ...
boolean loop = ...

int streamId = pool.play(soundId, 1.0f, 1.0f, 1, ( loop ) ? -1 : 0,
1.0f);

...

if(streamId != 0){
pool.stop(streamId);
streamId = 0;
}

[android-developers] Re: How much money do you make?

2010-09-22 Thread Michael A.

On Sep 21, 10:35 pm, Indicator Veritatis mej1...@yahoo.com wrote:
 So the moment the first post in this thread went up, I knew we were
 going to see some responses painting a rosy picture of glowing
 success. But that doesn't really tell us much.

I haven't seen any claims on this thread that I find outlandish by any
means.

At, e.g., $3 a sale, $100 per day is only 33 sales per day = about
10-15K downloads over a year. There are several hundreds of paid apps
that have broken the 10K downloads mark, so I am not surprised to see
several people reporting such income. Note that both niko and Doug -
the two who have cited $100 a day, specifically point out that their
apps have been on the market for a long time = most likely top ranked
apps. These are not apps that have made big money for years - most
likely their current level has only been reached in recent months as
the number of Android devices has gone through the roof.

Of course, one should put their success in perspective by noting that
of 45K+ paid apps, only about 3% have 1000 downloads and less than 1%
have 5000 downloads (according to Androlib). So obviously, success of
that kind is rare and not to be expected for the average app.

The sad thing is that, by iPhone standards, these tales of glowing
success are laughable. Consider for instance Trism (big hit on the
iPhone - sold 50K units in its first 2 months @ 5$) has yet to break
the 500 download mark on Android. Obviously, success is all about
being in the right place at the right time with the right product, but
but such a huge disrepancy in sales can hardly be put down to only
luck. I am looking forward to reading Polyclef's blog when he takes
status of sales on iPhone/Android for his latest cross-platform app
whether he finds the trend of iTunes being immensely superior to the
Android market continuing.

Currently (again according to Androlib), Android has 27 paid apps with
more than 50K sales. Only 1 (Robo Defense) has gone over 250K in
sales. That should really tell people everything they need to know
about the profitability of the market for a regular starting
developer.

If you have the name recognition, of course, big hits are still
possible. Angry Birds will certainly make a killing when it comes on
the paid market. Judging by their download data, the Moron Test is
making well over $600 a day now (5000 downloads between Jun 29 - Jul
11; 40,000 downloads from Jul 11 to Sep 7 @ $0.99). So really good
sales are clearly possible, if you have the right IP.

[android-developers] Re: Where has maps.jar gone to? Can't find in basic SDK install

2010-09-22 Thread Lance Nanek

If you are using Eclipse you shouldn't be accessing the maps.jar
manually anyway. Right-click on your project in Eclipse, choose
Properties, choose Android, and check a build target that has Google
APIs as the Target Name. That adds it to your build path for you. If
you don't have a Google APIs build target listed, you need to go to
Window, then Android SDK and AVD Manager, then Available Packages, and
download one.

Re: [android-developers] Please help me with calculating direction from point A to B


I'm really not understanding how to go with this...

I've been reading and reading.. I can find all kind of algorithms.. I  
can find a haversin algorithm that points me to the correct direction  
if my device is pointing north.. but the needle is static... so if i  
change the device orientation the measure is incorrect... and I know  
this happens because I'm not using device's sensor values like  
azimuth, pitch and roll.. oh god.. 2 weeks on this.. I'm just  
desperate now.

Pedro,

If I understand you correctly, you are having difficulties with the  
device's orientation.


The bearing angle seems to be computed in the horizontal plane. If  
you wish to adjust for the device's orientation, you need to  
concatenate it with the bearing angle.


Google for quaternions.

This is a (relatively) simple math technique to work with rotations  
the same way you can work with vectors: add / subtract, interpolate.

Hi everyone...

I'm back with the same issue for the last couple of days… I'm  
trying

to create a compass for my application BUT the difference is that,
instead of having a line always pointing to north, I want this line  
to

point for a specific point. I've been trying dozens of algorithms and
nothing works..
I've finally found one that points me exactlly to the point I want..
BUT it doesn't move if I change the position of the device which is  
my

objective.. basicly, what I want is that no matter the direction I'm
using my device.. the line always point me to the point
(picLatitude,picLongitude)…

I understood that for the line to move, I can't use static  
variables…

I need to use the values offered by the onSensorChanged(SensorEvent
event).

This are the data I have available:

event.values[0]: azimuth, rotation around the Z axis (device in
relation to north, 0º)
event.values[1]: pitch, rotation around the X axis
event.values[2]: roll, rotation around the Y axis
mLatitude: device current latitude gottern from GPS (variable)
mLongitude: device current longitude gotten from GPS (variable)
picLatitude: static picture latitude established previously
picLongitude: static picture longitude established previously
distance: distance in Km from device to the picture calculated
previously

And this the formula that works correct, and gives me the correct
angle.. ( BUT IT DOESN'T USE ANY OF THE SENSOR DATA SO THE LINE
COMPASS DOESNT MOVE):

double dLong = picLongitude - mLongitude;
double y =  (Math.sin(dLong) * Math.cos(picLatitude));
double x =  (Math.cos(mLatitude) * Math.sin(picLatitude) -
Math.sin(mLatitude)*Math.cos(picLatitude)*Math.cos(dLong));
double angleDegreesWrongRange = Math.abs(Math.toDegrees(Math.atan2(y,
x)));
float angleDegrees = (float) ((angleDegreesWrongRange+360) % 360);

myCompass.updateDirection(angleDegrees);

I got this bearing formula from this website:
http://www.movable-type.co.uk/scripts/latlong.html


Can someone please help me with this?
I've try adding, subtracting… the azimuth.. I've tried with the
others.. seriously at this point I'm just demoralized..

Thank you in advance

Just compensate the error that is introduced by not actually pointing the

I've tried it.

Adding and subtracting the value: event.values[0], which is actually  
my Azimuth in degrees returned by the sensor.


But the orientation is off! ..

The algorithm gives the Correct value, but it doesn't move because  
there's not sensor variables involved.. so if I subtract the error it  
points in the wrong direction

[android-developers] Service: both onStart() and onStartCommand() called

2010-09-22 Thread Christoffer Davidsson

Hello (World).

I'm trying to create a Service which is backwards compatible, working
on both pre-2.0 and post-2.0 phones.
Therefore I implement both onStart() and onStartCommand() according
to: 
http://developer.android.com/reference/android/app/Service.html#onStartCommand(android.content.Intent,
int, int).
Where the comments on onStart() say:
// This is the old onStart method that will be called on the pre-2.0
// platform.  On 2.0 or later we override onStartCommand() so this
// method will not be called.

However, running 2.1 in the Emulator, both methods are called when I
start my Service. Is this a bug? Did anyone else have this problem?

Dianne thanks for your answer.

Well, at the moment I don't want to place my Launcher on the Market,
but only to do it for a private use on my Froyo 2.2 device.
My idea is to compile the default Launcher in Eclipse and to modify/

How can I do this? I'm thinking to re-compile Android from source
code, is the right way?

Please answer me.

 If you are doing this to create something you will place on Market, you

 If you are doing this as part of platform development for a device,

 Any tricks one uses to build Launcher in Eclipse without fixing the code
 will *not* create an application that should be placed on market.  (And if
 you do, I can guarantee that future versions of the platform will break the

Setting clickable to false lets clicks through to what is underneath

 .setSelected(false);

 Maybe its better to understand if I tell you that I want to create my
 own dialog without extending the class Dialog.

 A dialog also puts a transparent glasspane above all and absorbs all
 clicks underneath...

 Thanks for helping,
 Marco

[android-developers] Re: Http chunked response and Connection Reset by Peer error

2010-09-22 Thread Cydrike

New information:

It seems that I don't receive Connection Reset by Peer errors because
Android has dropped the connection.

My exact test case is the following:
- I start my application which creates the request with the previous
posted code
- the app reads the request response waiting for the server
- I put the device in sleep mode by pressing the power button
- I wait 5 minutes (nothing special happens in logs apart from garbage
collector actions)
- I wake up the mobile and force the server to send me something
- Nothing arrives on the mobile anymore, the connection is stucked on
the read

No error can be seen in logcat, no exception is raised.
It seems that Android has just stop using my connection.

Is there some kind of mechanism that kill idle connections while in
sleep mode ?

  A lost connection (not gracefully closed) generally can't be detected on
  the client. TCP/IP does not transmit data unless your application does,
  so a lost connection looks the same as a connection that simply doesn't
  have any data to receive.

  There is a TCP/IP option to do keepalives at the protocol level,
  SO_KEEPALIVE, but I wouldn't count on it working reliably all the way
  from the phone to the server.

  I recommend you look at Google C2DM (Cloud 2 Device Messaging).

   Hi everyone,

   I'm facing an annoying problem here.
   My application is connected to a server that sends some data from time
   to time. It's some kind of eventing server. In order to receive data,
   I'm connecting to the server with an HttpURLConnection, retrieve the
   response InputStream and loop on it with the read method. The
   connection is always open.

   The distant server is cutting the connection every 5 minutes (for test
   purpose). When connection is closed, my application has to reconnect
   again. We detect a Connection Reset by Peer exception when the server
   closes the connection. The problem is that most of the time, I never
   receive the Connection Reset by Peer exception. So my application
   can't know that is has to reconnect and it's stucked on the read
   instruction.

   The InputStream.Read() method shouldn't always raise an exception if
   the connection is closed?
   What can I do to always detect Connection Reset by Peer exception?

   Thanks for any help,

   Android 2.1

Re: [android-developers] Please help me with calculating direction from point A to B

Pedro,

I think you should learn something about the way direction (and
orientation) is specified in computer programming.

http://en.wikipedia.org/wiki/Yaw,_pitch,_and_roll

http://en.wikipedia.org/wiki/Euler_angles

http://en.wikipedia.org/wiki/Rotation_representation_(mathematics)#Rotation_matrix_.E2.86.94_Euler_angles

I believe that Android orientation sensors work this way.

Now about the compass

There are two ways you can think about this:

First, take the value you get from the algorithm and make it into a
vector in 3D space (i.e. think of the arrow you're going to draw to
indicate direction). Then:

One: Compute the device's orientation matrix using sensor data. Take the
inverse of this matix, and multiply the arrow vector by this matrix.

Two: Compute the device's orientation matrix using sensor data. Rather
than interpreting it as a rotation matrix, think of it as defining a
plane in space (aligned with the device's screen). Then project the
arrow vector onto this plane, in the plane's coordinates.

You might want to start with compensating just for the vertical axis
(the device's rotation from the true north direction), it might be enough.

I'm really not understanding how to go with this...

I've been reading and reading.. I can find all kind of algorithms.. I
can find a haversin algorithm that points me to the correct direction
if my device is pointing north.. but the needle is static... so if i
change the device orientation the measure is incorrect... and I know
this happens because I'm not using device's sensor values like
azimuth, pitch and roll.. oh god.. 2 weeks on this.. I'm just
desperate now.

Pedro,

If I understand you correctly, you are having difficulties with the
device's orientation.

The bearing angle seems to be computed in the horizontal plane. If
you wish to adjust for the device's orientation, you need to
concatenate it with the bearing angle.

Google for quaternions.

This is a (relatively) simple math technique to work with rotations
the same way you can work with vectors: add / subtract, interpolate.

Hi everyone...

I'm back with the same issue for the last couple of days… I'm trying
to create a compass for my application BUT the difference is that,
instead of having a line always pointing to north, I want this line to
point for a specific point. I've been trying dozens of algorithms and
nothing works..
I've finally found one that points me exactlly to the point I want..
BUT it doesn't move if I change the position of the device which is my
objective.. basicly, what I want is that no matter the direction I'm
using my device.. the line always point me to the point
(picLatitude,picLongitude)…

I understood that for the line to move, I can't use static variables…
I need to use the values offered by the onSensorChanged(SensorEvent
event).

This are the data I have available:

event.values[0]: azimuth, rotation around the Z axis (device in
relation to north, 0º)
event.values[1]: pitch, rotation around the X axis
event.values[2]: roll, rotation around the Y axis
mLatitude: device current latitude gottern from GPS (variable)
mLongitude: device current longitude gotten from GPS (variable)
picLatitude: static picture latitude established previously
picLongitude: static picture longitude established previously
distance: distance in Km from device to the picture calculated
previously

And this the formula that works correct, and gives me the correct
angle.. ( BUT IT DOESN'T USE ANY OF THE SENSOR DATA SO THE LINE
COMPASS DOESNT MOVE):

double dLong = picLongitude - mLongitude;
double y = (Math.sin(dLong) * Math.cos(picLatitude));
double x = (Math.cos(mLatitude) * Math.sin(picLatitude) -
Math.sin(mLatitude)*Math.cos(picLatitude)*Math.cos(dLong));
double angleDegreesWrongRange = Math.abs(Math.toDegrees(Math.atan2(y,
x)));
float angleDegrees = (float) ((angleDegreesWrongRange+360) % 360);

myCompass.updateDirection(angleDegrees);

I got this bearing formula from this website:
http://www.movable-type.co.uk/scripts/latlong.html

Can someone please help me with this?
I've try adding, subtracting… the azimuth.. I've tried with the
others.. seriously at this point I'm just demoralized..

Thank you in advance

Re: [android-developers] Re: Http chunked response and Connection Reset by Peer error

 Like I said before, detecting a broken connection on the receiving end 
is difficult, since TCP/IP does not have keep-alives. That's left up to 
the application protocol.


Perhaps what you could do is have your application periodically send 
small amounts of data, just to make sure the connection is still there. 
Just make sure your server can deal with it - actually read the data 
past the initial HTTP request, if only to drop it on the floor.

[android-developers] How to create an executable file for android

2010-09-22 Thread Lidia G

I found how to use an android library, from the eclipse 
http://developer.android.com/guide/developing/eclipse-adt.html#libraryProject 
but this is not what i need, i need to comples a library into a jar file and to 
hide the code that can be used from the library.

And i can't create a JAR file using usually jar command from the JDK, because, 
my classes contain some android specific code.

How can i create an executable JAR file from android.
Please help me.

Hello people,

Can someone tell me  how to create an executable jar file from eclipse
for android?
First of all, how the application should be before creating a jar
file? Should it be runnable?  Do i need an Activity class in it?

I created a simple Android application, which has an activity class:
//--
public class MyClass extends Activity {
    @Override
    public void onCreate(Bundle  savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}
//--

and some other classes. I don't need this activity class in my jar
file, i need only all other simple classes,
I used from the eclipse the option Export -Java -JAR file
As i see, this option creates a simple jar file, it packs the classes,
so their content is invisible, but at the same time, the JAR file
content can be changed. e.g i can assign values to static parameters.

But i need an executable/unchangeable jar file.
If i use from eclipse the option Export -Java -Runnable JAR file -
the Launch Configuration: is empty, and i can't go on

What should i do

Please help me
Lidia

[android-developers] gps and wifi

2010-09-22 Thread student

Dear Android Developers,

  In location we have 2 way
1.gps
2. network

in above 2 of them are treated the seperate thread as thread1 and
thread2

in that if user inside the room gps not shown the latitude and
longitude so it should be activated the network side as thread2
then if user moved out it will be activated both gps and network.
my problem is if user came back to room it should be indicated the
network by comparing the frequency or  speed with gps?
how to do that comparision? what method we have to use in it?

Below is a shabby but simple piece of code that i am experimenting with..
The onReceive function does have a context - But i just register a

import android.os.Bundle;

@Override
public void onReceive(Context context, Intent intent) {
Log.d(PrankAApp,BEGIN1);
if(intent.getData()!=null)
{
Log.d(PrankAApp,intent.getDataString() );
}
else
{
Log.d(PrankAApp,DataString == NULL );
}
Log.d(PrankAApp,intent.toString());
TelephonyManager myTelManager =
(TelephonyManager)context.getSystemService(context.TELEPHONY_SERVICE);
MyPhoneStateListener myListner = new MyPhoneStateListener();
myTelManager.listen(myListner,
PhoneStateListener.LISTEN_CALL_STATE);
}

private class MyPhoneStateListener extends PhoneStateListener
{
private static final int CALL_STATE_RINGING = 1;
private static final int CALL_STATE_IDLE = 0;

public void onCallStateChanged (int state, String incomingNumber)
{
if (state == CALL_STATE_RINGING) {
resolveNumber(incomingNumber);
}
}
}

private void resolveNumber ( String incomingNumber)
{
int duration = Toast.LENGTH_SHORT;
CharSequence text = incomingNumber;
Toast toast = Toast.makeText(this, text, duration); *=== How do i

toast.show();

[android-developers] Java Guru Query: override a method taking a reflected class argument

2010-09-22 Thread Pent

Since API 7, PhoneStateListener has a function:

void onSignalStrengthsChanged( SignalStrength signalStrength )

Question: how can I override this via reflection so that I can stay
backwards
compatible with earlier APIs that don't have the SignalStrength
class ?

If I make the argument an Object, the signature changes of course.

TIA,

Pent

[android-developers] Trouble with TableLayout wrapping text

2010-09-22 Thread Doug Gordon

I have a 2-column table where the right-hand column in the rows might
have too much text to fit on one line, so I wanted it to wrap and
expand the table cell similar to the way it would work on a web page.
This turned out to be more difficult than I expected. When I
configured that TextView to wrap_content for both width and height,
the text would wrap, but not correctly. Some of the text was missing
as though the lines were extending past the right edge of the screen.

I finally solved it by putting shrinkColumns on the 2nd column; the
text wraps and it's all there. But I'm still curious as to what the
problem was with the off-screen wrapping. The table is fill_parent
wide, so how can a row exceed its width? And why did shrinkColumns fix
it?

[android-developers] Re: Please help me with calculating direction from point A to B

2010-09-22 Thread Per

this works for me:

1: listen to location changes. Store the most recent location. You
need it below.
2: listen to orientation changes. Store the most recent heading
(azimuth) in mHeading - that's the compass direction corresponding to
your viewing direction when holding your phone horizontally in
portrait mode;
3: the bearing to your destination (assuming you have its coordinates)
can be found using Location.distanceBetween() (call it mBearing)
4: to point your directional arrow towards the destination, its
required rotation (from 'up') is  ((mBearing - mHeading)+360) % 360;

You may wish to compensate for device rotation (portrait/landscape),
too. See Display.getOrientation / Display.getRotation

Not a complete 3D solution, but works ok.

naval use, but hey...)

   Pedro,

 I think you should learn something about the way direction (and
 orientation) is specified in computer programming.

 http://en.wikipedia.org/wiki/Yaw,_pitch,_and_roll

 http://en.wikipedia.org/wiki/Euler_angles

 http://en.wikipedia.org/wiki/Rotation_representation_(mathematics)#Ro...

 I believe that Android orientation sensors work this way.

 Now about the compass

 There are two ways you can think about this:

 First, take the value you get from the algorithm and make it into a
 vector in 3D space (i.e. think of the arrow you're going to draw to
 indicate direction). Then:

 One: Compute the device's orientation matrix using sensor data. Take the
 inverse of this matix, and multiply the arrow vector by this matrix.

 Two: Compute the device's orientation matrix using sensor data. Rather
 than interpreting it as a rotation matrix, think of it as defining a
 plane in space (aligned with the device's screen).  Then project the
 arrow vector onto this plane, in the plane's coordinates.

 You might want to start with compensating just for the vertical axis
 (the device's rotation from the true north direction), it might be enough.

  The bearing angle seems to be computed in the horizontal plane. If

  concatenate it with the bearing angle.

  Google for quaternions.

  This is a (relatively) simple math technique to work with rotations
  the same way you can work with vectors: add / subtract, interpolate.

  Hi everyone...

  I'm back with the same issue for the last couple of days… I'm trying
  to create a compass for my application BUT the difference is that,
  instead of having a line always pointing to north, I want this line to
  point for a specific point. I've been trying dozens of algorithms and
  nothing works..
  I've finally found one that points me exactlly to the point I want..
  BUT it doesn't move if I change the position of the device which is my
  objective.. basicly, what I want is that no matter the direction I'm
  using my device.. the line always point me to the point
  (picLatitude,picLongitude)…

  I understood that for the line to move, I can't use static variables…
  I need to use the values offered by the onSensorChanged(SensorEvent
  event).

  This are the data I have available:

  event.values[0]: azimuth, rotation around the Z axis (device in
  relation to north, 0º)
  event.values[1]: pitch, rotation around the X axis
  event.values[2]: roll, rotation around the Y axis
  mLatitude: device current latitude gottern from GPS (variable)
  mLongitude: device current longitude gotten from GPS (variable)
  picLatitude: static picture latitude established previously
  picLongitude: static picture longitude established previously
  distance: distance in Km from device to the picture calculated
  previously

  And this the formula that works correct, and gives me the correct
  angle.. ( BUT IT DOESN'T USE ANY OF THE SENSOR DATA SO THE LINE
  COMPASS DOESNT MOVE):

  double dLong = picLongitude - mLongitude;
  double y =  (Math.sin(dLong) * Math.cos(picLatitude));
  double x =  (Math.cos(mLatitude) * Math.sin(picLatitude) -
  Math.sin(mLatitude)*Math.cos(picLatitude)*Math.cos(dLong));

[android-developers] ACTION_VIEW exception

2010-09-22 Thread Neilz

I try and open up a new activity, pointing to the market, with the
following code:

Intent i = new Intent(android.content.Intent.ACTION_VIEW);
i.setData(Uri.parse(myMarketDetialsHere));
startActivity(i);

It works fine on the device, but the Emulator throws an Exception:

android.content.ActivityNotFoundException: No Activity found to handle
Intent { action=android.intent.action.VIEW data=market://search?
q=MyMarketDetailsHere }

I'm not sure if this is just an emulator thing, or whether this could
replicate on a real device?

[android-developers] Re: LVL returns LICENSED with anonymous accounts...

I do see this behaviour too (though dev account on emulator and test

not publishing it) to see if that then gives back what I set in the

My understanding from the server team is that uploading a draft 
version is
supposed to be sufficient to avoid getting ERROR_NOT_MARKET_MANAGED. 
(In the
case of existing applications, you'll also need to increment your 
version
code.)

The other way you'll avoid this is precisely as Mark mentioned. If we
don't find the application, we check to see if the current user has a
developer account, and will send a test response (if one is set) using 
the
user's RSA keypair.

[android-developers] Drawing a line dynamically in code

2010-09-22 Thread Kevin Courtney

Hello,



This seems like a basic question but I’ve been struggling with it and need
another set of eyes to set me straight.



I’m trying to draw a line using code in a RelativeLayout and it’s not
showing up.  I have this XML file:



?xml version=*1.0* encoding=*utf-8*?

shape xmlns:android=*http://schemas.android.com/apk/res/android*

android:shape=*line*

stroke android:width=*1dp* android:colora=*#FF*/

size android:height=*15dp* /

/shape



I use this file when drawing a line from straight XML and it works fine.


But now I’m trying to use it to draw a line dynamically, in this code…



ScrollView sv = *new* ScrollView(*this*);

  RelativeLayout relativeLayout = *new* RelativeLayout(*this*);

 relativeLayout.setBackgroundResource(R.drawable.*gradient_box*
);



  sv.addView(relativeLayout);



  ImageView imageLineView2 = *new* ImageView(*this*);;

  imageLineView2.setBackgroundResource(R.drawable.*dividing_line_1*);

  RelativeLayout.LayoutParams lpEndOfInfoLineId2 =

   *new* RelativeLayout.LayoutParams(

*   *RelativeLayout.LayoutParams.*WRAP_CONTENT*,

 RelativeLayout.LayoutParams.*FILL_PARENT*);

  relativeLayout.addView(imageLineView2,lpEndOfInfoLineId2);



  // have buttons, text, and images here that show up fine.



  *this*.setContentView(sv);



It uses the same background as my successful use from the XML file so I
don’t think it’s blending into the background.



Do any of you have any suggestions on what I’m missing?



Thanks in advance,



Kevin

My guess is that when the version of the app making thecheck  is lower
than the latest in the market, LICENSED_OLD_KEY is returned as per
http://developer.android.com/guide/publishing/licensing.html#server-response-codes

Is the version of the app making the check higher, then that should be
you testing a new version and you can overwrite via the dev console I
guess.

 market.  If the version code in the copy of the app making the check
 is less than or equal to the current one in the market, then the
 normal license valid/invalid response is given unless there's another

 That seems acceptable to me, even if it is a bit odd considering the

 The code of my class looks as follows:

         private static final int DATABASE_VERSION = 1;

         private static String[] FROM = { _ID, SITE_IDENTIFIER, SITE_URL, };

 }

 Within my activity I do the following:

 try{

 this.openOrCreateDatabase(SITES_DATABASE_NAME, MODE_PRIVATE, null);
                         WebsiteData data = new WebsiteData(this);

                 } catch(Exception e){

                 }

 As you can see the Exception is written to the log at exactly this try-
 catch-block. I squeezed the hell out of Google but couln't find any
 solution yet.

 Any help is highly appreciated.

[android-developers] Re: ACTION_VIEW exception

Unless I am remembering wrong, the emulator doesn't have market.

It would also happen if someone manages to get your apk onto a device
without market (of which there are many, especially non-phone tablets)

 It works fine on the device, but the Emulator throws an Exception:

 android.content.ActivityNotFoundException: No Activity found to handle
 Intent { action=android.intent.action.VIEW data=market://search?

 I'm not sure if this is just an emulator thing, or whether this could

You could also try doing a $adb shell wpa_cli save_config after adding a

[android-developers] Determing end of Scroll View scroll

2010-09-22 Thread ben

Is there any way you to determine the pixel value where a scroll view
stops on a fling. It's easy enough to find when the user is scrolling
the view with a touch but I see no way to determine the end point of a
fling. The only solution I could come up with is to use a gesture
detector to catch a fling and then calculate where it would stop based
on the velocity, is that the best way?

I'm trying to create a view that will indicate to the user when there
is more to scroll to, and then have the indicator vanish when the
scroll view is at the beginning or end.

hmm this is strange. The warning is normal but it should still work.

We're fixing this for the next version of the tools, but as Dianne

You can target 2.1 (API 7).

[android-developers] Threading and the emulator

2010-09-22 Thread kypriakos


Hi all,

Are there any limits on the number of threads or any constraints
on how the emulator (under Eclipse) schedules the application
threads? I get suspended threads that don't really wait on anything
but rather get bumped out from execution time ... I will try using the
Debug class to get some statistics on the thread alloc etc. even
though
the DDMS does that already.

One example is, I have a simple class that simply prints a '.' every
3 seconds - well, the LogCat shows the emulator collecting garbage
objects but the thread is suspended and does not print the '.' ... I
may
be missing something simple here

Thanks

For the next tools update we should probably rename our task to

 Let me rephrase that: it's a good app, but it doesn't support X so I'm

 My personal feeling is not that feature X will turn his 1 star rating

Essentially.  Though you might want to decide what should happen when
it inevitably finds its way to a device without market - ie, fail
gracefully with minimal reduction in functionality or Your device
does not support this application or Your device is not authorized
to run this application or This is a pirated install.  Fail! -
essentially depending on how you feel about people re-distributing
your app via other channels in non-market countries and communities

I believe that Android orientation sensors work this way.

Now about the compass

There are two ways you can think about this:

First, take the value you get from the algorithm and make it into a
vector in 3D space (i.e. think of the arrow you're going to draw to
indicate direction). Then:

One: Compute the device's orientation matrix using sensor data.  
Take the
inverse of this matix, and multiply the arrow vector by this  
matrix.


Two: Compute the device's orientation matrix using sensor data.  
Rather

than interpreting it as a rotation matrix, think of it as defining a
plane in space (aligned with the device's screen).  Then project the
arrow vector onto this plane, in the plane's coordinates.

You might want to start with compensating just for the vertical axis
(the device's rotation from the true north direction), it might be  
enough.

Pedro,



If I understand you correctly, you are having difficulties with the
device's orientation.



The bearing angle seems to be computed in the horizontal plane. If
you wish to adjust for the device's orientation, you need to
concatenate it with the bearing angle.



Google for quaternions.



This is a (relatively) simple math technique to work with rotations
the same way you can work with vectors: add / subtract,  
interpolate.

Hi everyone...


I'm back with the same issue for the last couple of days… I'm  
trying

to create a compass for my application BUT the difference is that,
instead of having a line always pointing to north, I want this  
line to
point for a specific point. I've been trying dozens of  
algorithms and

nothing works..
I've finally found one that points me exactlly to the point I

is my

I'm

I understood that for the line to move, I can't use static  
variables…
I need to use the values offered by the onSensorChanged 
(SensorEvent

event).



This are the data I have available:



event.values[0]: azimuth, rotation around the Z axis (device in
relation to north, 0º)
event.values[1]: pitch, rotation around the X axis
event.values[2]: roll, rotation around the Y axis
mLatitude: device current latitude gottern from GPS (variable)
mLongitude: device current longitude gotten from GPS (variable)
picLatitude: static picture latitude established previously
picLongitude: static picture longitude established previously
distance: distance in Km from device to the picture calculated
previously



And this the formula that works correct, and gives me the correct
angle.. ( BUT IT DOESN'T USE ANY OF THE SENSOR DATA SO THE LINE
COMPASS DOESNT MOVE):



double dLong = picLongitude - mLongitude;
double y =  (Math.sin(dLong) * Math.cos(picLatitude));
double x =

apparently this is a common error that many beginners get -
Resources don't contain package for resource number 0x7x.

However, what's the explanation when the R.java does not call
for any of the resources that the emulator is complaining about?
Who and/or where are these calls originating from otherwise?
None of the imported packages import their own R.java ..

 Hello,

 This seems like a basic question but I’ve been struggling with it and need
 another set of eyes to set me straight.

 I’m trying to draw a line using code in a RelativeLayout and it’s not
 showing up.  I have this XML file:

 ?xml version=*1.0* encoding=*utf-8*?

 android:shape=*line*

     stroke android:width=*1dp* android:colora=*#FF*/

 I use this file when drawing a line from straight XML and it works fine.

 But now I’m trying to use it to draw a line dynamically, in this code…

 ScrollView sv = *new* ScrollView(*this*);

       RelativeLayout relativeLayout = *new* RelativeLayout(*this*);

              relativeLayout.setBackgroundResource(R.drawable.*gradient_box*

       // have buttons, text, and images here that show up fine.

       *this*.setContentView(sv);

 It uses the same background as my successful use from the XML file so I
 don’t think it’s blending into the background.

 Do any of you have any suggestions on what I’m missing?

Hi Martin,

Thought you would want to know and you can make it known to the rest
of
our fan boys...

We didn't get banned from posting anything. We deliberately didn't
post
anything today for a few reasons:

-Adding some firewalls to server [For douche bags trying to DDOS
us :)]
-Analysis of the way you guys would react. Seems weird how the
comments on
FREE apps don't even get noticed. Maybe a turn for the better...
-Tracking some other stuff I wont deliberate on.

But be sure to check again in a few days or tomorrow for more ;)

Also you guys may want to stem your efforts to other sites as we
aren't
the only one or the biggest. Oh! and we buy all the apps! and keep
them! No
refunds on anything.

One more thing... That guy John commenting above you.. I like him
lol...
But yea, currently we have all requested apps removed, and plan to
keep it
that way. Now mind you we have a method to just hide them from view
but we
don't. I respect the wishes of developers who request removal.

All those downloads you guys see as non-paid aren't from us, like I
said
we should be the least of your concerns. We do not crack apps either.
Check
out the biggest site... ask around some may know the site I am
referring to
as they know the BIG dramatic take-down of it months ago.

There users CRACK ALL apps not us. We do not have the time to do it.
Plus
its not worth it. Especially when others will do it.

But yea, I'll answer questions for devs through you as long as you
post
what I type and nothing else or less. Not evil over here...

I am amazed how he thinks that he is not evil. As if only cracking
or not paying for the app would make it evil and otherwise it it ok.
Anyhow, I wrote back:

I am baffled by your attitude. You think anybody cares if you buy the
apps or not? That's $2 in my pocket, I am supposed to be grateful for
that? Every copy you distribute of my app, is stealing $2 out of my
pocket.

Imagine all Android users would use your site rather than buying
through the market. This is certainly something you would want, no?
Then the developers get paid once and that's it, and most of us would
stop developing because we need to feed our families and need to get
paid for our work.  The result is that you will find only apps by
school children and apps by companies for advertising purposes. That's
what you work towards. I love Android, I love the ability to
contribute apps to the Android community and you are actively working
on destroying that.

I feel violated and hurt by you. Your attitude disgusts me. There is
absolutely nothing legal or justifiable about your making money of
other people's work. You should be ashamed. Why don't you write apps
yourself and contribute to Android? That's too hard? Thieving is
always easier.

[android-developers] Re: Scaling / Animating a Camera preview surface

2010-09-22 Thread Jon Sutherland

Anyone have any insight at all?  Was I not clear about my problem?

I am simply trying to zoom in or zoom out on the camera preview but I
am not using the Camera smooth zoom API in 2.2 since it seems to only
work for levels of zoom that are different for each phone/camera.
Also, it appears that it can not zoom using a floating point scale.

If I try scaling the FrameLayout around the preview SurfaceView it
looks like it kind of works, but the preview goes completely black
while the animation is running.

I am starting to think maybe this will work by grabbing each frame
from the preview and drawing to a canvas white scaling, but this seems
over-complicated compared to using the Animations API.

If someone can help point me in the right direction that would be
awesome!

Thanks,


Jon

2010-09-22 Thread pawpaw17

Lance,

Thanks for the reply. What build target should I be using if I want to
continue support Android 1.5 and forward with google maps?

The project build target dialog has the following target names:

Android 1.5 Platform 1.5
Andorid 1.6 Platform 1.6
Android 2.1 Platform 2.1
Android 2.2 Platform 2.2
Google APIs Platform 2.2

The thing that worries me about the last one is the Platform 2.2. We
need to support all of the existing versions of Android.

Also, if I do a search on my hard drive, maps.jar doesn't even exist
on the machine after installing the full set of Android APIs.
As and experiment, I switched to the Google Apis build target, and I
still get errors for the maps stuff.

Still presuming I'm doing something wrong...

My code seems fine but the direction of the arrow doesnt seem accurate:


public void onSensorChanged(SensorEvent event) {
	double mLatitude  =  (mLocation.getLatitude()); // lat1 location  
manager
	double mLongitude =  (mLocation.getLongitude()); // long1 locationg  
manager
	double picLatitude = Double.parseDouble(picLatitudeString); //lat2

	double picLongitude = Double.parseDouble(picLongitudeString); //long2  
fixed

float mHeading = event.values[0]; // azimuth value
float[] results = new float[1];
Location.distanceBetween(mLatitude, mLongitude, picLatitude,  
picLongitude, results);

float mBearing = results[1]; // bearing
float angleDegrees =  ((mBearing - mHeading)+360) % 360;

myCompass.updateDirection(angleDegrees);
}

The update method goes simply like this:

public void updateDirection(float dir)
{
firstDraw = false;
direction = dir;
invalidate();
}

And this is how I draw the compass:

public static class compassLook extends View {

private Paint paintPointer = new Paint(Paint.ANTI_ALIAS_FLAG);
private Paint paintCircle = new Paint(Paint.ANTI_ALIAS_FLAG);
private Paint paintLeters = new Paint(Paint.ANTI_ALIAS_FLAG);
private boolean firstDraw;
private float direction;

protected void onDraw(Canvas canvas) {
int cxCompass = (getMeasuredWidth()/2);
int cyCompass = (getMeasuredHeight()/2);
float radiusCompass;
if(cxCompass  cyCompass){
 radiusCompass = (float) (cyCompass * 0.9);
}
else{
 radiusCompass = (float) (cxCompass * 0.9);
}
// circle drawing
canvas.drawCircle(cxCompass, cyCompass, radiusCompass, 
paintCircle);
if(!firstDraw){ 

// line pointer
 canvas.drawLine(cxCompass, cyCompass,
		   (float)(cxCompass + radiusCompass * Math.sin((double)(-direction)  
* 3.14/180)),
		   (float)(cyCompass - radiusCompass * Math.cos((double)(-direction)  
* 3.14/180)),

   paintPointer);
double mLatitude  =  (mLocation.getLatitude()); //lat1
double mLongitude =  (mLocation.getLongitude());//long1
double picLatitude = 
Double.parseDouble(picLatitudeString); //lat2
double picLongitude = 
Double.parseDouble(picLongitudeString); //long2


 // Distance formula (harversin)
float R = 6371; // km
float dLat = (float) 
Math.toRadians(picLatitude-mLatitude);
float dLon = (float) 
Math.toRadians((picLongitude-mLongitude));
float a = (float) (Math.sin(dLat/2) * Math.sin(dLat/2) +
			Math.cos(Math.toRadians(mLatitude)) * Math.cos 
(Math.toRadians(picLatitude)) *

Math.sin(dLon/2) * Math.sin(dLon/2));
float c = (float) (2 * Math.atan2(Math.sqrt(a), 
Math.sqrt(1-a)));
float distancia = R * c;

		 canvas.drawText(String.valueOf(distancia*1000) + m, cxCompass-30,  
cyCompass+20, paintLeters);

}

}

I didn't wrote all the methods on compssLook since they are not

You may wish to compensate for device rotation (portrait/landscape),

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

2010-09-22 Thread Mariano Kamp

As it wasn't possible to submit a new post to the existing/old conversation
using the web interface I am copying the message here with Danilo's
permission:

Hi Mariano.

Did you manage to work using themes from drawables xml?
I have same problem and there is no any reference but this thread and
there is no solution here.
If you find solution please let me know.

I currently solved it by using different drawable xml for every
theme but as you can see this isn't a god solution at all.

About your question about getting a color from a theme (I know its old
but for future readers :) ) solution I created is like this:

   private static int getColor(final Context context, final int id,
final int defaultColor) {
   try {
   final Theme theme = context.getTheme();
   if (theme == null) {
   return defaultColor;
   }
   TypedValue typedValue = new TypedValue();

   if (theme.resolveAttribute(id, typedValue, false)) {
   final Resources resources =
context.getResources();
   final int resourceId = typedValue.resourceId;
   if (typedValue.type ==
TypedValue.TYPE_INT_COLOR_RGB8 ||
typedValue.type == TypedValue.TYPE_INT_COLOR_RGB4 || typedValue.type
== TypedValue.TYPE_INT_COLOR_ARGB4
   || typedValue.type ==
TypedValue.TYPE_INT_COLOR_ARGB8 ||
typedValue.type == TypedValue.TYPE_FIRST_COLOR_INT) {
   return typedValue.data;
   } else {
   return
resources.getColor(resourceId);
   }
   }
   return defaultColor;
   } catch (NotFoundException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
   return defaultColor;
   }
   }

 Hi Dianne.

 Thanks very much, almost there.

 I understand the procedure, it would do what I want, but I run into an
 exception:

 D/NewsRobDefaultExceptionHandler( 1839): Caused by:
 java.lang.UnsupportedOperationException: Can't convert to color: type=0x2

 This happens when using it the way we described here in a drawable xml.
 However to better understand the error I used it on other attributes and
 when using it on the background attribute of a View it works. Maybe this
 approach is incompatible with drawables that are expressed in xml?

 Btw. Is there any way to get the actual #rgb string for a color from a
 theme?

 Cheers,
 Mariano

 On Tue, May 11, 2010 at 8:02 AM, Dianne Hackborn hack...@android.comwrote:

 You need to define an attribute for your value:

 attr name=myColor format=color /

 Then make a custom theme that supplies a value for it:

 style name=MyTheme parent=android:Theme
 item name=com.my.package:myColor#ff808080/item
 /style

  And now you can reference that value from other XML:

 shape xmlns:android=http://schemas.android.com/apk/res/android

 
 android:shape=rectangle
 gradient android:startColor=?com.my.package:myColor

 android:endColor=#66FF
 android:angle=270 /
 /shape


 Note that com.my.package is your manifest's package name.

 Also I just wrote this by hand so I won't guarantee it is completely
 right. :}

 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

[android-developers] Re: Drawing a line dynamically in code

2010-09-22 Thread Kevin Courtney

I'm not entirely sure if it's the draw method that I should be
using..at this point I'm looking for any suggestions...

...I need to draw a line on the on this view using code.

The rest of the story is that this code is inside a loop that is
reading records and putting their info on the view.  In between each
record I want to draw a simple line.

Thanks,

  Hello,

  This seems like a basic question but I’ve been struggling with it and need
  another set of eyes to set me straight.

  I’m trying to draw a line using code in a RelativeLayout and it’s not
  showing up.  I have this XML file:

  ?xml version=*1.0* encoding=*utf-8*?

  shape xmlns:android=*http://schemas.android.com/apk/res/android*

  android:shape=*line*

      stroke android:width=*1dp* android:colora=*#FF*/

      size android:height=*15dp* /

  /shape

  I use this file when drawing a line from straight XML and it works fine.

  But now I’m trying to use it to draw a line dynamically, in this code…

  ScrollView sv = *new* ScrollView(*this*);

        RelativeLayout relativeLayout = *new* RelativeLayout(*this*);

               relativeLayout.setBackgroundResource(R.drawable.*gradient_box*
  );

        sv.addView(relativeLayout);

        ImageView imageLineView2 = *new* ImageView(*this*);;

        imageLineView2.setBackgroundResource(R.drawable.*dividing_line_1*);

        RelativeLayout.LayoutParams lpEndOfInfoLineId2 =

         *new* RelativeLayout.LayoutParams(

  *           *RelativeLayout.LayoutParams.*WRAP_CONTENT*,

       RelativeLayout.LayoutParams.*FILL_PARENT*);

        relativeLayout.addView(imageLineView2,lpEndOfInfoLineId2);

        // have buttons, text, and images here that show up fine.

        *this*.setContentView(sv);

  It uses the same background as my successful use from the XML file so I
  don’t think it’s blending into the background.

  Do any of you have any suggestions on what I’m missing?

  Thanks in advance,

  Kevin

[android-developers] LogCat and threads

Hello,

I am trying to understand threads and how they work, and when, etc. I
expected the pid in LogCat to be different in the background thread
logs but the pid is always the same.

Is the pid something other than the thread ID? If it is, is there a

[android-developers] Re: Automatic testing tool for Android?

(There is a tool that lets you send button clicks.  Don't know
anything about it, but it was mentioned in a post a few days ago.  My
impression was that it's a daemon of sorts that runs on the phone
(perhaps through adb) and that you can send commands to it like press
100 100 to press the button at those coordinates.)

Re: [android-developers] LogCat and threads

Process is not the same as thread. A process can have many threads, and they
all share the same data. This is really convenient, since you can reference
Java objects from any thread, regardless of which thread created them.
Processes, on the other hand, do not share each other's memory state - so
your Java objects can't be accessed by other applications.

Note that in Android UI related framework calls have to be made from the
main thread, called the UI thread.
