[android-developers] how PUSH Tech in android ????

[Mohsin Yasin]

Hi!
i am facing an problem?

problem:
server (web server) wants to send data( or some information) to mobile
client (android based phone).
means simply notify to start work, then mobile start working on specific
application.

i would like to do a SMS from server to mobile, to start working. buts its
not the best idea.
as we can assign too an IP to android mobile phone in case of WiFi or USB
connectivity.
but phone will use GPRS or GSM, so there is no unique IP of Mobile so that
we can access mobile phone using Socket Programing
so there is any idea or tutorial for this mention problem.

dont give the example that GMAIL, or black beryy etc using these technology,
actually tell me how technically its work
thanks
waiting for your good replies

[android-developers] How to connect a context menu to a spinner popup?

[Walles]

Hi!

I have a spinner that I've read from an XML file.  When I click the
spinner, it pops up a list of stuff.  I'd like to connect a context
menu to the popped up list.  How can I do that?

I have attempted registerForContextMenu(Spinner), but that adds the
context menu to the spinner itself rather than the list it pops up.

  Help! //Johan

Spinner setup code:
http://bazaar.launchpad.net/~walles/sl/trunk/annotate/49/StockholmPublicTransport/src/com/johan/sl/SL.java#L140

Spinner XML (it's the fromSpinner and the toSpinner that I want to
provide with context menus):

[android-developers] Re: get outgoing call details in background

[Nemat]

@Roman

But How would we get the state when the call is received?I mean call
duration means the difference of the time when call is received and
the time when the call is disconnected.OFFHOOK is the state when caLL
is placed.So we should be notified when the call is received.How can
we get that?

@nEx.Software

if its not possible with service then it is of no use for me.

Anyways is there any way to read the call-log in service?

[android-developers] Re: app gives layout errors only on Sprint HTC Hero devices

[Jayesh Salvi]

I tried to look into the android framework code
(link). The topmost frame refers to a 'throw'
statement(line 512) that is inside a catch of a lower level exception. I
can't tell what part of the createView() function throws that lower level
exception.
I also tried to search around for the error string "Error inflating class
java.lang.reflect.Constructor", but couldn't found one with a similar stack
trace. (There are known crashes with this error message caused inside
android.preference.* package, but mine is a simple widget layout and not
preferences, as you might have seen in the XML file I attached earlier.)

I now have 9 reports of this crash and all of them are confirmed to be using
Sprint HTC Hero devices. This problem hasn't been reported on any other
phone. Is it fair to assume that it's a problem in that particular ROM? If
that's so, then what options do I have to resolve this issue - should I wait
helplessly for HTC/Sprint's next update?

Any suggestions are appreciated.

Thanks.

[android-developers] Re: How can I package shared libs only into apk

[Dianne Hackborn]

You should use the NDK.  If you are compiling as a platform component,
things are very different, and you won't have you code inside of a .apk.

[android-developers] Re: stopped unexpectedly when run on emulator

[Dianne Hackborn]

Oh and my writing code that catches and consumes an exception, you are
preventing the system from doing the normal thing of logging the full error,
 As a general just don't do catch (Exception e).  If you really really for
some strange reason are doing that, log the entire exception (using Log.w
with the exception as the third argument) so when it does happen you can see
the actual error.

You need to provide the -full- stack crawl including, very importantly, all
of the "caused by" clauses which tell you the actual original errors that
happened.

[android-developers] Re: How to categorize the installed applications similar to Android Market

[Dianne Hackborn]

Sorry, there is no way to do this -- that information is currently just
internal to the market app, not part of the platform at all.

[android-developers] How to categorize the installed applications similar to Android Market

[Riyaz]

I am developing a launcher application.
I want to display the installed applications in categories like
Android Market.
Say if i have installed an application from category Communication, I
want to show that application under Communication category in my
launcher.
How do i get the category (Android Market category) information of an
application?

[android-developers] Re: detecting application loss of screen control

[David Bernstein]

This is true.  However, my application, which comprises many
activities, is the one starting (most) activities not started by the
HOME key, which can't be intercepted (googling "android intercept home
key" will bring up multiple discussions of this).  I would prefer not
to have my app needlessly hammer the system every time it starts up
one of its own activities.

For now, I'm going with the almost-good-enough approach of updating
its (zero, one, or more) app widgets when the root task closes (in its
onPause(): isFinishing() is true, would also use isTaskRoot() if the
task weren't always rooted by the same activity).

I think it would be helpful if the API provided
Activity.isTaskSwitching() and/or Activity.isApplicationSwitching()
and maybe something to tell when being killed by the OS (e.g. for
memory) for use in onPause() so that an application can tell that it's
losing control.

[android-developers] Re: Stripping Log._ out of production

[stanlick]

Would the Application class be a good place for this?

The android.app.Application class

The android.app.Application is a base class for those who need to
maintain global application state. It can be accessed via
getApplication() from any Activity or Service. It has a couple of life-
cycle methods and will be instantiated by Android automatically if
your register it in AndroidManifest.xml.

Reputedly, MOTODEV Studio for Android has some sort of IP-based
debugging that you might be able to use for that.

Try ProGuard, proguard.sourceforge.net.

There are a couple of optimizations that don't interact well with the
Dalvik bytecode verifier; those will be fixed in a future release.  In
the mean time you can disable them from the ProGuard config.  (I don't
have a link to the article(s) handy; if you encounter problems you can
google for it.)

Config.DEBUG is always false for the downloaded SDK so now I get it

Config.DEBUG is not deprecated contrary to post from Dianne, although
other fields in Config are deprecated starting in 1.6.  For some
reason it seems like you have read the source to find out what is
deprecated since it is not shown in the API docs.

[android-developers] Users have trouble upgrading my app in Android Market - anyone else?

[pawpaw17]

I've had more than one user say they have trouble when they "upgrade"
new versions of my app in Android Market. One woman says it takes her
several "days" to successfully do it (I presume that means multiple
attempts spread out over time).

Can this be on my end? I upgrade my database on each rev - basically I
retreive the user data and stick it in the new database that ships
with my app. But I think the complaint is about something different.

Has anyone else received comments about anything similar? I am
concerned people uninstall my app just because of this issue,.

Thanks!

[android-developers] Re: Problems playing MP3s on real device

[Marco Nelissen]

Tested it on a number of phones, including a Hero, and it worked as
expected. Note that there are many different versions of the Hero
being sold though, so the problem you are seeing could be specific to
the particular build on the phones you tried.

[android-developers] Re: HTTP GET and ProgressDialog

[Lee Jarvis]

Ok so I updated the code again, and I guess it pretty much works.
Would any of this be discouraged? Or would there be a better way of
doing this?

[android-developers] Re: Retrieving the saved state of the Custom View in the constructor.

[B++]

I understand that making a network request inside the view is not
recommended, but I need to treat the Custom View as a widget which
hides the implementation details. I want to handle everything (even
the configuration changes) in the view itself.

Thanks

[android-developers] How does Log.isLoggable() work?

[jotobjects]

Just playing around with Log.isLoggable(tag, level) method.

Log.d(LOGTAG, "--- debug log");
Log.i(LOGTAG, "--- info log");
if (Log.isLoggable(LOGTAG, Log.INFO)) Log.i(LOGTAG, "---
isLoggable info log");
if (Log.isLoggable(LOGTAG, Log.DEBUG)) Log.d(LOGTAG, "---
isLoggable debug log");

These all send output to the log except the last.

Following the instructions in the API for Log.isLoggable I used adb to
set the value of LOGTAG to DEBUG as follows -

# setprop com.foo.bar DEBUG

where "com.foo.bar" is the value of LOGTAG. But the 4th Log still does
not print.  I tried stopping and restarting the emulator and removing
and reinstalling the app and setting the property before the app
started. No luck so far.

I was assuming the mechanism would allow me to turn up the logging
verbosity on a running app, but so far I don't get isLoggable to do
anything at all.  Any suggestions?

Related questions:
- What API call will get the values that you see with "adb shell
getprop"?
- isLoggable suggests creating a /data/local.prop file.  Is the idea
to copy that file onto the device or is there another way?

It's not necessarily an error. Surface FLinger is trying to access several

Don't do an asynchronous network request from a View. I realize that
Android isn't necessarily the ideal MVC platform, but I really recommend
you separate your concerns more than that.

[android-developers] Re: Alarm is canceled if app is stopped

[Lazarus 101]

Thanks Dianne for the quick answer.

Actually TasKiller is not automatically killing apps, but it has a
widget that allows users to kill (almost) all apps with one click.
Most of the Android users that I know are using something similar to
TasKiller so this is a tricky problem, users will blame my app for not
doing what it says it does.
I saw there is a PACKAGE_RESTARTED broadcast but obviously the
restarted package does not receive the notification so there's not
much I can do to "fix" this problem...

Having applications that can affect the functionality of every other
apps installed on the system is not such a good idea IMHO. A Task
Manager is needed but the user should be clearly informed that the
apps he choses to kill are not working anymore because that's exactly
what he wanted. Also the permission is called "restart other
application" it should be "kill other applications", that's why I
thought alarms are not affected by this and that services are getting
restarted (I saw services being restarted after crashes or after being
killed due to lack of memory so I though it's the same behaviour when
calling ActivityManager.restartPackage).

[android-developers] Retrieving the saved state of the Custom View in the constructor.

[B++]

The "View" instance currently provides a way to retrieve the saved
state using the methods below, but there doesn't seem a way to
retrieve the view's saved state in the constructor, or
onFinishInflate. The custom view is constructed via XML, so I cannot
pass the saved bundle from the Activity to the View's constructor.

Relevant methods:
- protected Parcelable onSaveInstanceState()  and
- protected void onRestoreInstanceState(Parcelable state)

I need this because I make an asynchronous network request in a custom
view constructor, and if there is a configuration (orientation)
change, the custom view is getting reconstructed, and the request is
getting performed again. I want to intercept the second request in the
constructor. I can do this in the onRestoreInstanceState, but I need
to handle this in the constructor.

It would be nice if there was a method such as getSavedState so that
the decision can be made in a constructor or onFinishInflate instead
of waiting for the onRestoreInstanceState trigger.

Any idea?

Thanks

[android-developers] Permission Denial - APPWIDGET_DELETED and APPWIDGET_DISABLED

very grateful.

On the emulator you always have data connectivity. For example with
enabling the Airplane mode you can still browse the web (which should
not be the case).

I submitted a bug on this (don't remember the bug number).

[android-developers] Re: Check for internet connection

This code seems to return true unconditionally.  Of course, I suppose
it could be the emulator, but here is the deal.  When I switch my wi-
fi off and try using the emulator browser, I get the built-in Android
404 page.  However, when my application tests for a net connection
using the code below, it returns true.

public boolean iCanHasDataNowKThxBye() {
ConnectivityManager connMgr=(ConnectivityManager)
getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info=connMgr.getActiveNetworkInfo();

return(info!=null && info.isConnected());

}

[android-developers] Custom Object Serialization in Android?

[dsukhram]

I am writing an android client app which sends a Hashtable to a remote
servlet and recieves an ArrayList consisting of a custom Object which
is serializable.  This ran fine when I was just receiving the
ArrayList from a java console app. So I know my objects are being
serialized and deserialized properly. But when I port the same client
code over to android I get an error when trying to read the ArrayList
of my objects that is sent back from the servlet.

Is there any differences in the way Android does serialization? I
can't seem to find any documentation that says it does. The error I
receive is:

java.lang.IndexOutOfBoundsException: Invalid location

   at java.util.ArrayList.get(ArrayList.java:350)

 My Android Client app is as
follows=

public class TTCPointService  {
private Logger logger;
private FileHandler handler;

public TTCPointService(){

try
{
logger = 
Logger.getLogger(TTCPointService.class.getName());
handler = new FileHandler("ttcservice.log");
handler.setFormatter(new SimpleFormatter());
logger.addHandler(handler);
}
catch(IOException e)
{
logger.log(Level.SEVERE,e.toString());
}
}

public ArrayList ConnectToServlet()
{
ArrayList list = new ArrayList();

Hashtableobj = new Hashtable();
obj.put("lat", "12.00");
obj.put("log", "-23.00");

try
{
URL servletURL = new URL("http://192.168.0.69:8080/
GTFSProcessor/TTCPoints");
HttpURLConnection servletConnection = (HttpURLConnection)
servletURL.openConnection();
servletConnection.setDoOutput(true);
servletConnection.setDoInput(true);
servletConnection.setUseCaches(false);
servletConnection.setDefaultUseCaches(false);

servletConnection.setRequestProperty("Content-
type","application/x-java-serialized-object");
servletConnection.setRequestMethod("POST");
logger.log(Level.INFO,"Connecting to Servlet");

//Send object to servlet
OutputStream os = servletConnection.getOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(os);
oos.writeObject(obj);

oos.flush();
oos.close();
logger.log(Level.INFO,"Hashtable sent to Servlet");

//Read from servlet
InputStream is = servletConnection.getInputStream();
ObjectInputStream ois = new ObjectInputStream(is);


list = (ArrayList)ois.readObject();
logger.log(Level.INFO,"Reading Object from Servlet");

os.close();

}
catch(IOException e)
{
  logger.log(Level.SEVERE,e.toString());
}
catch(ClassNotFoundException e)
{
logger.log(Level.SEVERE,e.toString());
}
return(list);

[android-developers] Re: Point Sprite support

[Scott]

All right. Perhaps a silly follow-on question. If the hardware
supports point sprites, but does not support non-power-of-two
textures, then can I support non-power-of-two image dimensions for my
point sprites? I realize I can copy an image into a portion of a
larger sized power-of-two texture, but I don't believe I can blit that
portion of the texture as a point sprite. Can someone please confirm?

Thank you,
Scott.

Specifying android:minSdkVersion="4" in the android manifest did the

[android-developers] Text Synthesis Missing Spanish in setLanguage

[dsurround]

I am interfacing with the Text Synthesis engine of 1.6.  I am trying
to set the language to Spanish.  I can set it to English, German,
French and Italian, but Spanish does not come up as an option.

myTts.setLanguage(Locale.SPANISH);  // this does not work
myTts.setLanguage(Locale.GERMAN);  // this works along with ENGLISH,
ITALIAN or FRENCH

Seems like it should be there.  Is that a known bug?  I can set it
through the setting interface, but need to set it programatically.

Please advise.

Thanks!

BTW, why are you creating the NinePatchDrawable yourself if you are

[android-developers] Re: Why does getPadding() of NinePatchDrawable throw a NullPointerException?

[Romain Guy]

NinePatchDrawable tagBalloon9pDrawable = new NinePatchDrawable(tagBalloon9p);

this creates a NinePatchDrawable with a null padding. That's why you
get an NPE. You need to specify the padding.

[android-developers] Why does getPadding() of NinePatchDrawable throw a NullPointerException?

[Anders]

I'm trying to use NinePatchDrawables in a LayerDrawable, but for some
reason I get a NullPointerException. I've isolated the problem to the
getPadding() method; the following code reproduces the problem:

Bitmap tagBalloonBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.balloon);
NinePatch tagBalloon9p = new NinePatch(tagBalloonBitmap,
tagBalloonBitmap.getNinePatchChunk(), null);
NinePatchDrawable tagBalloon9pDrawable = new NinePatchDrawable
(tagBalloon9p);

Rect r = new Rect();
tagBalloon9pDrawable.getPadding(r);  <<-- Throws NullPointerException!

What am I missing? Do I have to do anything special with the
NinePatch? The program seems to work if I use the NinePatch directly
(instead of putting it in a LayerDrawable).

Any suggestions and help is greatly appreciated.

[android-developers] JJIL (image processing library)

[benjamin.grant.du]

Hi all,
just trying to get the face detect software found here(http://
code.google.com/p/jjil/) not because I want to do face detect but I
need to edit the code for another purpose. However, first I just want
the original code to work so I can understand it. I import face-detect-
android as a new project. I then get the errors that jjil and jjil-
android are required projects and they're missing. therefore I add
them both as external jars to the build path.  The error does not go
away - and I'm confused as to why. Any suggestions?
Ben

Look at the system log (either using "adb logcat" or with the ddms

[android-developers] Autogrow ListView is not working

[droidin.net]

I look at some posts from the past and it seems that if I add items to
the ListView adapter it should update itself and user should be able
to scroll to the newly appended items. Unfortunately it's not what I
observe. If I append new items to my existing ArrayAdapter I only will
see updated results if I rerun ListView#setAdapter again. Doing
nothing, invalidating view etc. doesn't do anything. Here's a snippet:

SearchItemsAdapter a = (SearchItemsAdapter) listview.getAdapter();
List values = fetchNextSetOfItems();
a.append(values);
// unless I do this - I will not see the update, but if I do - I'll
jump to the top
listview.setAdapter(a);

Here's append method:

public void append(List values) {
this.items.addAll(values);
}

Anything I'm missing?

[android-developers] Re: Problem using ksoap2 in Android

[claudiotainen]

Same problem here:
org.xmlpull.v1.XmlPullParserException: unexpected type
(position:END_DOCUMENT n...@1:0 in java.io.inputstreamrea...@4413ee)

I wonder if you managed to solve it. If not, have you tried checking
the xml soap request that is sent out of your client?
I'm using
androidHttpTransport.debug = true;
System.out.println ( androidHttpTransport.requestDump );
to examine the xml code that is generated bu ksoap2.

The strange thing is that I can successfully invoke other operations
of my ws, while it seems that this request can't even be "assembled"
by the parser.
I've also noticed that changing versione from 1.1 to 1.2 the exception
thrown is different, and it refers to the START_TAG.

More to come (hopefully) in the near future...
Cheers,

Claudio

[android-developers] data exchagne on client/server applications

[Robert]

Hello list,

this is my first post and I don't hope you get this question like
everyday.
I am not new to Java, but new to Android development and am thinking
about making a classical client/server application.
The question for me is: What is the most painless way to do the data
exchange? I really dont want to start making my own protocol with
sockets, rather thought about some xml-exchange, maybe via http or
xmpp. Is any of these well supported in the android libs or the libs
usually present on android devices? Like serializating objects into
xml and back and then sending them via stream (xmpp) or packets (http)
from one direction to another?
How would you solve this?

Looking forward for inspirating answers,
Robert

[android-developers] Re: Noob question...using class variables inside listeners

[Streets Of Boston]

Two solutions:

Remove the 'this':
   okIntent.putExtra("com.example.challenge_no",
   challenge_number);// This is the problem line
   startActivity(okIntent);
   finish();

Or add Example.:
   okIntent.putExtra("com.example.challenge_no",
   Example.this.challenge_number);// This is the
problem line
   startActivity(okIntent);
   finish();

[android-developers] Problems playing MP3s on real device

[Adrian]

Hello,

I'm desperately trying to get my soundboard application to work. I
have a GridView consisting of Buttons, which have an OnClickListener
starting the sound file associated with the button. The sound files
are stored as MP3 (64 kbit/s, LAME encoded) audio files in the res/raw
folder and are referenced using the R class.

The following problem only occurs when running the app on a real
device, however, on the emulator it works perfectly. I have tried two
different HTC Hero so far.

I have a mysterious problem, that everytime I press a button to play a
specific sound, ALL sounds in the res/raw folder are played in the
order they are listed there. My current code to play a sound looks
like this:

if (player != null) {
player.stop();
player.release();
}

player = MediaPlayer.create(this, resId);

if (player != null) {
player.start();
}

As you can see I use a "singleton" MediaPlayer to play the files. I
have also tried using a new separate MediaPlayer instance for each
sound file, with the same result. Additionally, I have tried playing
the sound file in a separate thread with the result, that only the
first time all sound files are played. After that, the buttons work as
intended.

You can take a look at the source code on the Google Code project
site: http://code.google.com/p/zappenduster-soundboard/

Thanks for your help!
Adrian

[android-developers] Re: Nesting an ActivityGroup as atTab content

yes, the list activity handling is not that hard to implement - maybe

answered. Thanks :)

[android-developers] How to make the android source code and SDK successfully by cygwin?

[chuck]

Hi all:

 The code was downloaded successfully by cygwin. But when I make
it, the errors were as follows:

PLATFORM_VERSION_CODENAME=REL
PLATFORM_VERSION=1.6
TARGET_PRODUCT=generic
TARGET_BUILD_VARIANT=eng
TARGET_SIMULATOR=
TARGET_BUILD_TYPE=release
TARGET_ARCH=arm

HOST_OS=windows
HOST_BUILD_TYPE=release
BUILD_ID=Donut

build/core/main.mk:359: sdk-only: javac available.
make: *** No rule to make target `/usr/lib/tools.jar', needed by `out/

I can make the NDK by cygwin and my tool chains are listed in the
following:
1. gcc version 3.4.4
2. GNU Make 3.81
3. java version "1.6.0_16

Dose anyone help me?
Thanks a lot!!

>From the API docs: "This method (System.currentTimeMillis()) shouldn't

Instead, see the SystemClock-class, SystemClock.uptimeMillis() in

The Java APIs work only with pixels. Your app is probably running in

But when I run my application on WVGA800 in the emulator the lines are
five pixels wide even though I called Paint.setStrokeWidth(3). The
same seems to happen with Drawable.setBounds(); the value I provide
gets multiplied by 1.5 internally.

If that's the case, how can I specify pixels instead of dips if I want
pixels?

Can someone clarify this?

[android-developers] 802.1X configuration?

[fba]

Hi all,

With the release of the features in 1.6, I am looking for the APIs
needed to write an app that can configure 802.1X.  Based on the API
documentation it looks like no official APIs were added to handle
this.   Am I missing something?

What is the best way to go about creating an 802.1X config in code?
Do I need to use JNI and link to a library that is included?  Or dig
around in the Android source to see how the built-in configuration
tool does it?  (That is my next step.  I just wanted to put this out
there in case someone has a better answer in the mean time.)

Thanks!

[android-developers] Re: The application android has stopped unexpectedly

[Marco Nelissen]

Instead of the "console", look at the system log (either using "adb
logcat" or with the ddms perspective in eclipse), and it will tell you
exactly where and why it crashed.

[android-developers] Need to know RPC design in android

[Vishal]

Hello all,
I am very new to the android world. I am concerned about the kernel

I am currently looking for document on RPC(Remote procedure Call) in
android. It seems like android uses SunRPC. But I do not find any
document related to RPC.
Can any please help in finding a decent document which briefs the RPC
design in android?

Looking forward to your replies

[android-developers] Vertical TextView

[fhucho]

Can I somehow make my TextView to be vertical - it should look like
normal TextView rotated 90 degrees. I want this because at the bottom
of the screen I have a SlidingDrawer widget with a TextView label and
when the screen orientation changes to landscape I want to display the
SlidingDrawer at the right edge of the screen - so it will be rotated
90 degrees.

[android-developers] Re: I get the "unable to start wifi"

[mehool]

Hey,

I had the exact same problem. I was able to connect earlier using WIFI
and was able to browse the web.

I have HTC dream android developer phone and had upgraded it to 1.6.
Everything was working fine unitl one fine day when wifi decided to
show me "unable to to start wifi".

after much ordeal, I was able to get it to start working again by
restoring factory default and that did the trick and it started
working again.

I tried different kind of things like downgrading (radio and recovery)
to androind 1.1 but was able to do so for some reason (I still donot
know the reason for this).

However since I got the wifi to enable again I think I might have to
be satisfied with it :)

[android-developers] Re: Where have all the Google employees gone?

[spocky12]

Yes, we've got the same kind of issue in our app.
For the records, here is the problem and the solution.
The problem lies in the Camera.startPreview : an error is reported in
logcat :
E/CameraService(  554): registerBuffers failed with status -38
followed by an exception :
java.lang.RuntimeException: startPreview failed

The problem is solved by changing the surface holder type :
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

On 1.5, commenting this line just hides the camera preview from the
surface (we don't want it to display directly, we only use it to
access to the video frame buffer), but does not crash.

[android-developers] Can android applications install it's shared library files(*.so) from own update server?

[killerfore]

Hello,

I'm designing an app which use its own native shared libraries (*.so).

And it can download new shared libraries from some update server (not
android market)

I wonder that these *.so files can be installed in android by my
android app?

And another question,

Other applications can also access these shared libraries installed by
my app. (If all apps have same userID)

Thanks in advance.

using the latest firmware (v 1.1.01) just released today,
debugging works now as expected. in the usb settings, you
have to switch to "debug profile".
furthermore, there is an ftp and samba server enabled,
so you can easily get access to the filesystem.

[android-developers] Remote Wipe /Hard Reset / Factory Default

Hello.

I would like to create application that will reset phone to factory
default. Is it possible create such application. Will I need root
access? I searched forum but i haven't found any hints about it. There
are some applications that can do hard reset. But either they are too
expensive or I haven't got access to the code. I would like to create
simple guard.

Thanks for any reply.

[android-developers] Re: Problem using ksoap2 in Android

[claudiotainen]

Same problem here:
org.xmlpull.v1.XmlPullParserException: unexpected type
(position:END_DOCUMENT n...@1:0 in java.io.inputstreamrea...@4413ee)

I wonder if you managed to solve it. If not, have you tried checking
the xml soap request that is sent out of your client?
I'm using
androidHttpTransport.debug = true;
System.out.println ( androidHttpTransport.requestDump );
to examine the xml code that is generated bu ksoap2.

The strange thing is that I can successfully invoke other operations
of my ws, while it seems that this request can't even be "assembled"
by the parser.
I've also noticed that changing versione from 1.1 to 1.2 the exception
thrown is different, and it refers to the START_TAG.

More to come (hopefully) in the near future...
Cheers,

Claudio

[android-developers] Noob question...using class variables inside listeners

[Tom]

There is a probably a very simple answer to this, but I would like to
do the following:


public class Example extends Activity {

private String challenge_number = "";

   .class code

Button ok_button = new Button(this);
ok_button.setOnClickListener(new View.OnClickListener()
{
   public void onClick(View args0)
   {
   Intent okIntent = new Intent();
   okIntent.setClassName("com.example",
"com.example.newPage");

   okIntent.putExtra("com.example.challenge_no",
this.challenge_number);// This is the problem line
   startActivity(okIntent);
   finish();
   }

}


It fails because the listener doesn't know what "this.challenge_no"
is.  Can anyone help me solve this problem of scope?

[android-developers] Re: Problem using ksoap2 in Android

Hi, I've got exactly the same problem...
I'm using ksoap2 and I do manage to call some methods of my ws, but
the parser keeps popping the same error when it tries to process a
specific soap message:

soap, it is ok!
By the way, don't know if this can help, but I've been using

androidHttpTransport.debug = true;
System.out.println("request: " + androidHttpTransport.requestDump);

to see the xml generated.
Also, I've noticed that changing soap version from 1.1 to 1.2 I get a
different error, this time concerning the START_TAG.
Hope this was somehow useful...
Please let me know if you find a solution for this issue.
Thank you,
Claudio


PS: I've noticed that a lot of users are facing similiar problems.
Lots of posts, but as far as I'm concerned no "ultimate" solution till
now...

[android-developers] Building android source in debug mode

[NimeshChanchani]

i have downloaded the source code of android and want to build it in
debug mode. Is there any document that decibes the build process?

i basically want to build the "opencore" project in debug mode so that
i can "step in" to the code.
i don't mind if other projects are libraries.

is there a sample application for the media player on android?

You can either select count(*) beforehand to know the total rows, or
if you're paging through the whole table then the next page when you
run it with "offset 100" you won't get any rows back if there were
<100 rows to begin with.

[android-developers] Setting Toast Orientation to be Different from the Activity Orientation

[Mark]

Hello,

I'm working on an application that makes use of the camera.  There is
a known issue with the HTC g1 (described here:
http://code.google.com/p/android/issues/detail?id=1193) that requires
the camera preview activity to be in Landscape mode in order for the
preview to work correctly.  I would like to be able to display Toast
messages in portrait mode while the main camera activity is set to
landscape.  I've tried creating a custom Toast per the directions at
http://developer.android.com/guide/topics/ui/notifiers/toasts.html,
but I don't seem to be able to change the orientation.

Can anyone suggest a way to accomplish this?

Thanks in advance for your help!

Mark

[android-developers] How to get the size of a component in onCreate?

[Anders]

Hi all,

I'm working on an application where I wan't to show a thumbnail image
on an ImageButton. This works when I scale the image to create the
thumbnail using a hard coded size, but I would really like to use the
button.getWidth() / getHeight() to calculate the size of the
thumbnail.

However the getWidth/Height returns zero in onCreate() - probably
because the layouting is not finished(?).

Is there any way to get the size of the component? Is there any
"onLayoutDone()" function that I could override, or how should one go
about doing this?

Any suggestions will be appreciated.

Best Regards,
Anders

Those users have rooted phones and they just somewhere exported the

[android-developers] People still using ADC2 entries

[CraigsRace]

I had a look at my server logs, it looks like people are still playing
my ADC2 entry (only about 30 people / day).

The users are spread out from all over the world (LA, NY, London,
Spain, France, ...).

Was there a way that users could keep the ADC2 apps?  I thought they
got deleted as soon as the user entered their ratings?

I don't mind that people are playing my game (I think it's great!).  I
just would have liked to keep some of the ADC2 apps too!  :)

[android-developers] Re: Alarm is canceled if app is stopped

[Dianne Hackborn]

That is intentional.  Stopping an application is there for the user to stop
everything associated with it -- processes, alarms, services, notifications,
etc.  They will not be restarted until someone explicitly does so (typically
this would be the user re-launching the app and having it do the appropriate
thing).

It sounds like TasKiller is abusing this API.  The API is there for the user
to explicitly stop an app from running without going to the most extreme
measure of uninstalling the app.  Trying to use it to automatically stop
things behind the user's back seems...  questionable, and probably not what
the user actually wants.

[android-developers] Re: Got doubles, want ringtone, how do I do it?

[niko20]

Hi Jack,

A while back I was able to get some Ogg vorbis code to work, but I
think it required a specific format input (22khz, 16 bit, stereo), and
of course it took a while to do all the math.

I've uploaded my test project to:

http://rapidshare.com/files/292161983/TestOgg.zip.html

you may have to figure out how to get your buffer into it, I haven't
looked at this project in a while.
