[android-developers] Re: Help needed -- There is no linked app associated with this client ID.
I have the same problem. I don't understand how to register 2 client ID (one for debug and one for production) in the Games services console. If the answer is known, please let me know. Le dimanche 27 octobre 2013 10:50:48 UTC+1, FReDD a écrit : Hi all, I'm becoming crazy with this one. I just published a game on Google Play and the game uses the Google Play Games services. Sign-in and leaderboards / achievements worked fined with the application signed with the debug key, but since I built and published my app using my release key, Google+ sign-on is impossible. I always get the infamous error *E/SignInIntentService(25004): There is no linked app associated with this client ID.* I double- and triple-checked everything : my app is published, the package name and SHA1 fingerprint are correct and match what I extracted from the release APK, I unlinked and relinked the app in the Google Play Console multiple times, but nothing works.

Re: [android-developers] Re: Help needed
Hi ,
findViewById() method is used to get the object of the view.
*example*:
*main.xml* contain one button i want to provide the action for this button,
so we need to create the object in the java file by passing id.
Button
android:id=@+id/btn_New
android:layout_width=wrap_content
android:layout_height=wrap_content
android:text=new
/
*MainActivity .java*
public class MainActivity extends Activity {
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
//creation of button object
*Button buttonclickme=(Button)findViewById(r.id.btn_New);*
once we crate the object of the button we can provide action
buttonclickme.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
//here we have to write the code to execute when button clicked.
}}
RegardsRegards,
Naresh.

[android-developers] Re: Help needed with GPS/TTS app
Hi, You will probably want to use a Service ( with a PARTIAL WAKE LOCK ) rather than an Activity assuming you are not already. GPS will keep going ok, not sure about TTS in a Service. Regards On Dec 8, 8:41 am, gotok ken0g...@gmail.com wrote: First of all, I am very much a beginner working on my first app, and I am stuck on a problem. My app uses GPS and TTS and is intended for use when I am skiing. It has a single screen which displays speed, odometer, altitude, and GPS coordinates. It also uses TTS to speak speed, odometer, altitude, and time at user selected intervals. I have it typically set to speak speed at 5mph intervals. So whenever the speed crosses 5mph, 10,mph, 15mph, etc either on the way up or down, the speed is spoken. Similarly, odomenter is spoken every mile, altitude every 1000ft, and time every quarter hour. It is implemented as a single activity and built for API level 8. The target device is a Samsung YP-G70CW MP3 player which runs Froyo 2.2.2. Everything works as intended when the screen is on. However, the behavior is not consistent with the screen off (the primary use mode), either by timeout or directly with the power button. Sometimes the TTS reporting continues to work fine just as with the screen on. More likely, it runs at a reduced rate where the odometer and time reports occur on time, but the speed reports are much less frequent than normal and are delayed. When the screen goes off, it will get into one of these two modes and then stay that way. When in the slow mode, if I turn the screen back on, it speeds up to normal. I have diagnostic TTS reports, pausing in the onPause override, and resuming in the onResume override, so I can hear that it pauses when the screen goes off. Now my many questions: 1. My app is paused, but it continues to run, either at full or partial speed. So what does it mean for an app to be paused? Is it reasonable to implement this kind of app as an activity, or is a service required? 2. What all happens when the screen goes off? The Android documentation notes that one function, Proximity alerts, are slowed down when the screen is off. Are other GPS functions slowed down also? 3. I have tried a PARTIAL_WAKE_LOCK acquired in the onCreate override, and released at the onDestroy override, but it seems to have no affect. I also added diagnostic TTS such that when I report time I also check whether the wake lock is held or not. Sometimes it is not held, so who could be releasing the wake lock? I would really appreciate any comments/advice to help me solve this problem. thanks... -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Help needed to troubleshoot code
Couple of things here...
1. You are calling run() on the thread, not the one you have defined in
your activity.
2. You don't want to call run() on the thread, you want to call start().
3. You either need to create a Runnable to post to the thread or you need
to extend Thread and insert your own code.
Try this:
private void doLogin()
{
LoginThread ltNew = new LoginThread();
ltNew.start();
}
private class LoginThread extends Thread
{
@Override
public void run()
{
// Your login code here
}
}
That is one option. Give it a try and see if it does what you need it to.

Try
android:layout_marginRight=5dp attribute in ur xml file to get
spacing on the right of the button.
So somthing lik
Button android:id=@+id/button1 android:layout_height=wrap_content
android:layout_width=wrap_content android:layout_marginRight=5dp/

In your screen1.xml file, add android:layout_marginTop=5dp,
android:layout_marginBottom=5dp .. etc for top, bottom, left and
right spacing. This is added as an attribute to ur Button tag.
so you can have somthing like
Button android:id=@+id/button1 android:layout_width=wrap_content
android:layout_height=wrap_content android:layout_marginTop=5dp
android:text=Buttom 1/
to have 5dp space on top of your button.
Try it =)

Hi, You can just start the service via an intent and also pass details about the function(s) you want executed, but you won't get anything returned from the function(s) invoked in the service being sent back to the activity directly, you will have to use the usual interfaces otherwise.

[android-developers] Re: Help needed for dealing with NullPointerException when calling functions on a service just after binding it
Thanks Chris for replying.
You are right in saying that android requires developers to write an
event-driven code and that effort needs to be put for designing the
whole chain of events.
But for the following case as shown below, I don't think one can get
rid of the NullPointerException thrown in onClick() method of
MyServiceClient; Unless instead of storing Service Interface globally,
one stores it locally.

{
//some lines
ServiceWrapperClass svc = new
ServiceWrapperClass(getApplicationContext());
//access the service
mService = svc.getService()//the
getService() method returns null
//Integer someValue = mService.someFunc(1,
2); //Moved the line into onClick() method
//using a button's onClick event to call some function on the

btn.setOnClickListener(new OnClickListener() {

Integer someValue =
mService.someFunc(1, 2); //

Re: [android-developers] Re: Help needed for dealing with NullPointerException when calling functions on a service just after binding it
I solved a similar issue by broadcasting that my service is actually active and running and then if my activity is active it receives that broadcast and does what it needs to do. This way the Activity always knows when the service is active. The onBind is not applicable to my situation as my Activity and Service are independent of each other. (Activity starts/stops Service but Service does not need Activity for anything else) On Friday, July 22, 2011 6:57:42 AM UTC-4, Mark Murphy (a Commons Guy) wrote: On Fri, Jul 22, 2011 at 4:35 AM, Animesh Sinha anime...@gmail.com wrote: You are right in saying that android requires developers to write an event-driven code and that effort needs to be put for designing the whole chain of events.

[android-developers] Re: Help needed for dealing with NullPointerException when calling functions on a service just after binding it
Executing the function calls in onServiceConnected() method is not
what is wanted as described in following case:
There is a Service Wrapper class where the binding/unbinding is
actually done.
The MyServiceClient is an Activity class used for invoking some
functions on the service using the Service Wrapper class, instead of
directly binding/unbinding to service.
In this case, a service client using the wrapper class cannot execute
the function calls on the service in onServiceConnected() method,
which is in a different file.
The NullPointerException is therefore still thrown when any function
is invoked on the service after initializing the service wrapper.

Re: [android-developers] Re: Help needed on porting Flixel Framework to Android. Current issue: switch from canvas draw to opengl es
Hello Mario, I saw you post on Flixel forum. Its good to hear from you. I do feel a little crippled because I dont know muchjava, and opengl is very new to me. First I will try to awser your questions. - How much of the original Flixel API should be covered? I dont know, but W. Eraser points out this necessity of using opengles render instead of canvas render. Looks like a very good point to work on, as some flixel visual functions dont work or are impossible on canvas. - How much has been ported so far? I'd actually just rip out the interfaces/class/method signatures and replace the implementations. Sorry, cant help much. I saw about a guy, one year ago, ported somekind of flixel to android, replacing the actionscript syntax with java, and working only on render and other little issues. That version was a lot bugged, and this new flixel2 was done by Wing Eraser. Looks like a as3 flixel, added a d-pad and the canvas render. The project page has more information. If its not bothering you, can you point me some books/links to study and get a better idea of your work on libgdx? Like, to know the roots of the thing? I've read about rendering using bit blitting, like canvas render, but thats all I know so far. Really thanks for your interest, if theres something I can do to help, please ask. Cheers, Zimbres. Ps: sorry the late reply. I was working on some deadlines these days. The more that is already available the better. 2011/4/28 Mario Zechner badlogicga...@gmail.com Neat, a Flixel Android port would indeed be a nice to have. I saw that the project is actually not an Actionscript 3 project but a Java based project. Might i suggest basing the Android Flixel port on libgdx [1]? Benefit: it would also run on the desktop (windows, linux, mac) and the nasty OpenGL ES stuff is pretty much hidden by the utility classes we offer on top of the GLES binding.

[android-developers] Re: Help needed
I agree with TreKing: you have defined your problem so large that you will have to understand a huge amount of stuff just to get started. Decompose your problem into smaller steps, each with a meaningful goal. That way you can deliver something small, then improve on it and allow your understanding to grow at a steady pace. For Example: 1. Decide on a piece of interesting outdoor artwork that is near to you. Find its co-ordinates. 2. Write an app that will display the location of that artwork on a map. 3. Enhance your app so that it will display and update the phone location as well as the artwork location. 4. Enhance the app so that pressing a button brings up a text screen containing information about the artwork. 5. Enhance the app so that pressing a button brings up a text screen and an audio commentary 6. Enhance the app so that the button appears only when the phone is within 20 meters of the artwork 7. Enhance the app you get the idea You should have a clear idea of where you want to get to in the end - but reduce the task down to much smaller pieces that are much more achievable. It would be better to have a project that does some simple stuff well rather than a lot of stuff badly or not at all. Good luck.

The idea is that the user first makes a selection between a couple of given categories, like say; Art galleries, Architecture and music. after the user has chosen a category, the application will show various locations that are relevant to the chosen category. Example: like for instance say the user chooses the category architecture he will get the locations of all the great architectural buildings within the given city or village he or she is in. the next step is that the user can connect the given locations whit one another to create a route between the locations Example: The user selects the firs location he wants to visit this will mark the start point of the route. when the next location is selected, it automatically will be connected to the first location and thereby creating a route between the locations. the final step is that the user will be navigated along the route he created. when the user arrives at a location he or she selected the application provides the user with information about the object that is based on that location. The information is provided in the form of audio speech and text information. Example: the user created a route along several outdoor art pieces he wanted to go and see. he starts up the navigation and follows the route.

[android-developers] Re: Help needed - Stopped by NoClassDefFoundError when using a java library - JmDNS
NoClassDefFoundError should tell you which class it didn't find.

This generally occurs when the class was compiled against version X of some library but is finding (incompatible) version Y when it loads.

Re: [android-developers] Re: Help needed with parsing some XML data !
Hi, I have a similar problem. I am parsing iso-8859-1 html page with a sax parser but having trouble to display it on _some_ devices (characters é è ... are replaced by random symbols). On some devide i have to use myString.getBytes(iso-8859-1) to display it correctly, and on some other devices, myString will be displayed correctly.

This means that we were not able to determine the exact document type, but that the document passed the XML well- formedness syntax check. If you wish to wish to perform formal validation of the document, you can use the Document Type: option of the validator. But also this has been found, even though I do not know how important this is : The DOCTYPE Declaration was not recognized or is missing. This probably means that the Formal Public Identifier contains a spelling error, or that the Declaration is not using correct syntax, or that your XML document is not using a DOCTYPE Declaration. Validation of the document has been skipped, and a simple check of the well-formedness of the XML syntax has been performed instead. Als, just to point out, at this point i CAN read out the XML stream by using the Xml.parse(is, Xml.Encoding.ISO_8859_1, new ExampleHandler(myAdapter)); method...

Seehttp://junit.orgas a starting point. (The Android SDK includes some limited version of JUnit I don't recognize. It's adequate for this purpose, but the full, modern version is better. For non-device testing, you're not restricted to the supplied one.) Basically, a test case is code that you can run to *automatically* test some specific aspect of a system. In this case, checking against a known set of XML (so it doesn't change), looking for the known desired result, and reporting failures (expected conditions not matching) and errors (unexpected exceptions thrown). This removes the variables from the equation. You're not depending on how things display, either in the UI nor in the log stream and windows. You're not dependent on a human to notice a problem. An best of all, you can automate it to always run when you build, so if you break later, you'll find out right away, while you know what you changed. And you can make changes freely, with the security of knowing that you won't have to go through some long test/debug cycle. I didn't answer your question about getting a stacktrace earlier, because you said NetBeans. I'm old enough to remember when NetBeans was the hot new thing -- but too old to remember how to do anything with it. Try using Eclipse and the ADK. It will show you the stack trace in the same way it shows any other stack trace, as if you were debugging locally. (I would expect NetBeans to, as well). Or you can catch the exception, and use exception.printStackTrace() to get it into the log (I'm surprised it's not already there). This isn't really an Android problem, and it's not necessary to debug it there. If you write your failing test cases, you can debug them on your desktop computer, get them working, and you should be set to go on the device. Another thing to realize is that not all character values you can come up with, are legal XML content. They *MUST* be valid printing Unicode characters. No random control characters -- for example, ISO-8859-1 byte values 0-31 (decimal). This will ALWAYS fail -- it is NOT well- formed XML.

[android-developers] Re: Help needed with parsing some XML data !
Well, to be honest your first idea was also mine :P So I already looked via Google but to be honest I haven't found that many clear discussions/ explanations... I also tried idea 2 and this is what I got : Congratulations The document located at http://x was successfully checked as well-formed XML. This means that we were not able to determine the exact document type, but that the document passed the XML well- formedness syntax check. If you wish to wish to perform formal validation of the document, you can use the Document Type: option of the validator. But also this has been found, even though I do not know how important this is : The DOCTYPE Declaration was not recognized or is missing. This probably means that the Formal Public Identifier contains a spelling error, or that the Declaration is not using correct syntax, or that your XML document is not using a DOCTYPE Declaration. Validation of the document has been skipped, and a simple check of the well-formedness of the XML syntax has been performed instead. Als, just to point out, at this point i CAN read out the XML stream by using the Xml.parse(is, Xml.Encoding.ISO_8859_1, new ExampleHandler(myAdapter)); method... The only problem that remains is when I try to write on-screen the values... Btw, is there a way to trasform such a String (for example from a Country ID=2 CName=Åland eilanden/ tag) to utf-8 ? I have experienced such a problem on the iPhone some time ago, it also received the data as ISO-8859-1 but the STring had to be encoded to UTF8 to be shown correctly onscreen On 4 feb, 11:47, Frank Weiss fewe...@gmail.com wrote: I have two ideas for you, Mobdev: 1) Google for not well-formed (invalid token) and see what other people have found regarding this error. 2) Go to validator.w3.org and see if the XML file in question is indeed valid or not.

passing them off to a log stream that doesn't know about UTF-8.
Try logging to a file. Or better yet, create test cases, and verify

statements.
But if you have any control or influence over the server -- fix the
problem there. ISO-8859-* should be of purely historical interest in
interpreting old documents. The first draft of ISO-10646 came out
nearly 20 years ago, and UTF-8 has been around for nearly 18 years.
The world is international. It's time to put a stake in the heart of

Another factor to consider is how you're getting access to those
characters. You must do this one of two ways:
1) Using a Reader set to read 8859-1
-or-
2) Using an input stream, giving the raw bytes to the parser, letting
it decode the 8859-1 characters.
You WILL FAIL (and this is probably your problem, would be my guess)
if you try to read using a Reader that's expecting UTF-8.
A stacktrace should show which problem you have.

I'd argue that it should have gotten it from the ?xml...
encoding=iso-8859-1? -- I'm a bit surprised it didn't. But it's
something I'd never rely on if I know the encoding.
Anyway, re: your problem below. It's probably working right, up to the
point of the log statement.
The log stream is probably taking those bytes, and then later they're
being interpreted as UTF-8. or it's taking the characters from the
string, and interpreting them as UTF-8 (via String.getBytes()) and
passing them off to a log stream that doesn't know about UTF-8.
Try logging to a file. Or better yet, create test cases, and verify
the correct operation of your code via test suite, rather than via log
statements.
But if you have any control or influence over the server -- fix the
problem there. ISO-8859-* should be of purely historical interest in
interpreting old documents. The first draft of ISO-10646 came out
nearly 20 years ago, and UTF-8 has been around for nearly 18 years.
The world is international. It's time to put a stake in the heart of
these national encodings.

Re: [android-developers] Re: Help needed with parsing some XML data !
Found attribute : Albanië instead of Albanié This suggests you are displaying UTF-8 text (which is was logcat does) as Latin-1. To wit: ë = 0xC3 0xAB which are UTF-8 for Latin1 0xEB. However, é is 0xEB, not 0xAB, so there's something else afoot. Also note that when you see the rectangle with the ? in it, most likely means you are trying to read a Latin-1 encoding as UTF-8. For example, 0xEB by itself is invalid UTF-8. It would require two additional bytes each with the top two bits of 10. But good progress, bring on the data to analyze this problem.

[android-developers] Re: Help needed with parsing some XML data !
Yeah, that's not what I mean by a test case.
See http://junit.org as a starting point.
(The Android SDK includes some limited version of JUnit I don't
recognize. It's adequate for this purpose, but the full, modern
version is better. For non-device testing, you're not restricted to
the supplied one.)
Basically, a test case is code that you can run to *automatically*
test some specific aspect of a system. In this case, checking against
a known set of XML (so it doesn't change), looking for the known
desired result, and reporting failures (expected conditions not
matching) and errors (unexpected exceptions thrown).
This removes the variables from the equation. You're not depending on
how things display, either in the UI nor in the log stream and
windows. You're not dependent on a human to notice a problem.
An best of all, you can automate it to always run when you build, so
if you break later, you'll find out right away, while you know what
you changed. And you can make changes freely, with the security of
knowing that you won't have to go through some long test/debug cycle.
I didn't answer your question about getting a stacktrace earlier,
because you said NetBeans. I'm old enough to remember when NetBeans
was the hot new thing -- but too old to remember how to do anything
with it. Try using Eclipse and the ADK. It will show you the stack
trace in the same way it shows any other stack trace, as if you were
debugging locally. (I would expect NetBeans to, as well).
Or you can catch the exception, and use exception.printStackTrace() to
get it into the log (I'm surprised it's not already there).
This isn't really an Android problem, and it's not necessary to debug
it there. If you write your failing test cases, you can debug them on
your desktop computer, get them working, and you should be set to go
on the device.
Another thing to realize is that not all character values you can come
up with, are legal XML content. They *MUST* be valid printing Unicode
characters. No random control characters -- for example, ISO-8859-1
byte values 0-31 (decimal). This will ALWAYS fail -- it is NOT well-
formed XML. If that's the cause of your exceptions, your two choices
would be to fix it on the server (probably by encoding this binary
data) or to preprocess the fake-XML into real XML before you feed it
to the XML parser.

Hi all
I am trying to write a sample program to record the video (say
camcorder application).
When i run my program using the emulator (I have android-sdk-
windows-1.5_r3) I see java.io.IOException: prepare failed. error in
logcat output.
Further I can see that I have came across this error when i call
MediaRecorder.prepare()
from CamcorderActivity.surfaceCreated()
But I am surprised to see that activity got launched and I am seeing
the camera preview! Again the preview is seen only in half of the
screen! Its weird!!!
Further when i do recorder.start() to record the video I get
java.lang.IllegalStateException. Yes this is obvious since the prepare
() has failed.
But the question is why prepare() has failed ?
Can someone please help me to understand whats happening here!
Am i missing something ???
thanks in advance

It works fine on mine service using java, hope php has similar

also check for wsdl with the browser. Those are some mistake I have
done earlier. But I go with the original j2me jar. On that implement
extra classes of ksoap2-android-full-2.1.2(two class in transport

in wireshark, i did not find any traffic sent out to the service
server. so, my guess is it did not get sent out at all.
