 My point was more that although there is no explicit law requiring

 from developers if those kind of animations suddenly stopped working
 in the latest handsets.

You are writing your own activity. You are not writing the home
screen. If you were to publish your RemoteViews to a non-home-screen
activity of a third-party app, the same anything goes environment
would apply.

Could a device manufacturer change the Android framework such that no
animations worked anywhere? Yes. That should fail the CTS, not
necessarily the CDD. The CDD leans more towards hardware stuff. If it
doesn't fail the CTS, that's a hole in the CTS.

 But having said that I realise I am on shaky ground here... as we are
 talking about homescreen apps which are not part of the framework per
 se.

More importantly, they are written by everyone from major device
manufacturers to solo developers.

 However, from the user's point of view (who I would guess in 99%
 of cases use the Home screen which came with their phone), it is part
 of the framework, they would naturally think it is due to that phones
 implementation of Android, rather than understanding it is the Home
 screen app itself.

This is an issue of user education as much as anything.

Don't get me wrong. IMHO, Samsung screwed up. I would think the same
thing of any other home screen implementer with the same limitation,
**unless such animation disabling was a specific feature of that home
screen**. And that caveat is the rub. Just as you don't like it when
home screen implementers block app widget layout animations, a home
screen implementer would not like it if they were *forced* to display
whatever a RemoteViews had in it. From Google's standpoint, it's a
whack-a-mole situation -- one developer's solution becomes another
developer's problem.

This is reminiscent of developers complaining about how such-and-so
IME does not honor certain android:inputType or android:imeOptions
values. IME developers can do what they want, and users can choose
what IME to run. Home screen developers can do what they want, and
users can choose what home screen to run. We need to teach users that
IMEs and home screens are replaceable, just as we needed to teach
Windows users in 1995 that they could, indeed, run a different Web
browser than IE. That will take time.

[android-developers] Send Email without user input

Hi,

My requirement is to build an app that will send email to user at
regular intervals but without any input from the user. Is there any
way to do that? I am aware of the javamail-android available at the
following link but would like to know of any other way (perhaps
something mentioned in the official android documentation).

http://code.google.com/p/javamail-android/

I am bit sceptical to use javamail-android because the source code for
the three jar files namely additionnal.jar, mail.jar, activation.jar
is not available.



Thanks,
Ambi.

Use JavaMail or another email API. Or, do the mailing from some Web
service that you host, and have your app talk to that Web service.

Re: [android-developers] Send Email without user input

2012-01-15 Thread Kostya Vasilyev

A particular device may have an Email application different from the
one in Android sources (e.g. HTCs and the new Samsungs come to mind).

The user may install any of the third-party Email clients (K9,
ProfiMail, Mail Droid, Enhanced Email, Yahoo Mail, Yandex Mail, )

The user may not have any email accounts configured.

The user may not want that email sent in the first place.

The user may not want to enter his email credentials into your application.

In short, your options are:

1) Use the standard intent to let the user bring up his preferred
email client, where the user will decide if he's going to send that
email or not

2) Use some kind of email library, most likely not with the user's
credentials, but some others (e.g. a Gmail account you will set up for
this purpose).

JavaMail comes from enterprise Java, but I understand there are
successful ports to Android. Do some more Googling, they're out there.

Or you could learn a bit about SMTP and write some code yourself - the
S in SMTP stands for Simple :)

additionnal.jar, mail.jar, activation.jar is available from the

Dump the heap and examine it using the Eclipse MAT plugin:

 My main  concerns are the  1-byte array  esp. the 2.039 MB
 I'm sure it is an Image or Bitmap  I just don't know which one

I strongly encourage you to dump the heap in Honeycomb or Ice Cream
Sandwich then, as they do a much better job than do earlier versions
of Android of reporting bitmap memory.

[android-developers] android and XML

Hello,

I have been reading up on how to use XML from within android. Apparently
the interfaces are SAX which allows callbacks to be called when each element
is processed, DOM which allows in-memory tree representations of XML, JAXP
which can be used to validate XML given an XML Schema, and JAXB which is
available but takes up 8MB or so of space and would be used to convert back
and forth between XML and some annotated Java classes automatically at the
aforementioned disk storage price. Apparently JAXB used to be used to
validate
but since JAXB 2.0 that function has been delegate to JAXB. Apparently there
are three DOM levels, and Android's JDK supports level 2:

http://developer.android.com/reference/org/w3c/dom/package-summary.html

plus the load/store facilities available in DOM Level 3 which AFAIK are
used to
serialize/deserialize XML instances to and from memory?

http://developer.android.com/reference/org/w3c/dom/ls/package-summary.html

Then there are a variety of other XML APIs which do not come with Android
the
most nototrious being xerces from apache foundation which used to not be
bundled with jdk. Since jdk 5 it is, but apparently people don't use it
because
java has its own DOM API. Why would you want to use it when java bundles
a DOM API already. What more can xerces offer? And what more does the
full xerces implementation offer if you were to add the xerces jar file to
your APK?

Anyways, in the end I decided I am going to use DOM to read my files and
simply
throw an exception if what I receive does not conform to what I expect. I
also want
to build my XML files with DOM prior to sending the XML over a network.

I'm not clear on the following: where do I find good docs on DOM for
Android. Is
the API all there is available? Several books such as the following:

http://www.amazon.com/Java-XML-Brett-McLaughlin/dp/059610149X/ref=sr_1_1?ie=UTF8qid=1326644460sr=8-1

seem to be somewhat obsolete and document xerces or obsolete APIs/issues
(such as org.apache.xerces.parsers.DOMParser
which now seems to be replaced with:

import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;

Anyways, any pointers to tutorials on using DOM on Android to process and
build XML using DOM welcome.
One useful link I found was the following:

Thanks for your input,

Re: [android-developers] Regarding screen orientation changes

2012-01-15 Thread James Black

If you control the other application (Application X), then when you launch
it pass in another value in the extra data part, and don't specify the
screen orientation, but, if the intent has this other value set correctly
then it is forced to landscape mode.

So, basically, the default is to not force the orientation, but give a way
for this other application to be able to request landscape mode.

To make it more flexible, you could just allow programs to request
landscape or portrait mode, if you want it more flexible.

 James,

 Thanks for your response.

 I am working on Email application, my requirement is to show all the
 screen orientation only in landscape mode irrespective of device
 orientation, only when it launched through one particular application
 (Application X). If i launch the Email app through some other applications
 (Application y and z), it should always follow the device orientation.

 So, to satisfy the above requirement, when Email application is  launched
 from Application x,  i have used the API setRequestedOrientation
 (ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE) to change the
 orientation. When my device is PORTRAIT mode, and when its launched through
 Application X, all the Email screens are initially launched in PORTRAIT
 (Device orientation )mode and then its switching back to LANDSCAPE mode
 (because of the above API). How to avoid this screen flickering ?

 Hope you will understand my problem.

 It sounds like your requirements, or understanding is off, so you may

 The confusion is, if you automatically switch to landscape  always then
 set it in the manifest.

 If you start in portrait mode then why switch them? Or what should happen
 differently on this orientation?

 Hi All,

 As far as i know, screen orientation can be changed by two ways, one is
 through Manifesto file and other is through code by setRequestedOrientation
 API.

 My requirement is to show the screen orientation in Landscape mode, only
 when it launched through one particular application.

 To satisfy the above requirement i cannot use the first solution, i.e..
 setting the screen orientation through Manifesto file, since it always
 launch the activity in the specified orientation. So, now I am forced to
 take up the second solution, i.e.. setting the orientation through code by
 calling setRequestedOrientation
 (ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE).

 I am facing a problem with this approach, if my tablet is in LANDSCAPE
 mode, this solution works perfectly fine. But when my device is in PORTRAIT
 mode, initially it launches the activity in PORTRAIT mode and immediately
 changes the orientation to LANDSCAPE mode. How this flickering can be
 avoided ? Please through some light to handle this requirement.

 Manifesto file snippet:

  activity

 android:name=.activity.setup.AccountSetup

 android:label=@string/account_setup_title

 android:theme=@style/AccountSetup

 android:configChanges=orientation|keyboardHidden

 /activity



 Code snippet:

 @Override

 public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

 if (App.SETUP_WIZARD_FLOW == true) {


 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);

 }

 setContentView(R.layout.main);

If the application is free this is a good choice, but if it is something
that people paid for, then forcing them to pay again just because you
change the package name would be really annoying, so for a paid version
supporting both may be better.

 No, Market doesn't allow that. Here's what you could do instead:

 Publish your app under the new company/package name and wait for it to be
 live. Once that's done, publish an update to your older app. That update
 should simply change the app into redirecting users to the new app on the
 Market and politely apologize for the inconvenience and ask them to remove
 the old app after installing the new one. You could also detect the old app
 when running the new one and, if found, suggest the user to uninstall it.

 You need to be careful though with the user data though. You should
 provide means for them to migrate that data from the old app to the new one
 *BEFORE UNINSTALLING IT* or they'll lose everything. Maybe an
 export/import procedure will do the job. If you do it right, it only takes
 a few seconds for them to export all the data from the old app and import
 it into the new one.

Re: [android-developers] android and XML

2012-01-15 Thread James Black

You may want to ask this on stackoverflow, but, more importantly, DOM takes
up more memory for the XML file, so why use that on a mobile device with
less memory?

Do you have a business need to prefer DOM over just processing the file?
 If not, then you may want to rethink what you are asking about.

[android-developers] send notification from service to activity

2012-01-15 Thread Goutom

Hi

In my application when I press a button then it starts downloading  in a
background service.
Its a huge file to download. Though I close my application it continues
downloading in service.
I want to notify in my activity when download finish. Please note the cases:

These cases after starting download.

1. If I close my application it stills downloading and after some time it
finish.
I don't need to notify the activity because the activity in not visible.

2. If I close my application it stills downloading and after some time I
starts the activity.
But download is not finish.I am in activity and after a while download
is finish.
I need to notify the activity because the activity is visible now.

How implement this feature in android ? Dont forget to share any idea.

Regards
Goutom

Well, my XML files are going to be varied but small in size, so memory
shouldn't be a problem.

I was wondering about the availability of good tutorials on Java XML DOM

This shouldn't be your concern, there is a vast amount of literature
(in the form of references, tutorials, etc...) on both XML, and DOM,
Android also has an XmlPullParser that you might want to look into,
I'm sure there are a fully sufficient number of tutorials on that as
well.

In general your choices in android are these three: dom, sax, and
xmlpullparser, plus whatever off the shelf parser you want to grab.
The stigma with dom is that there's a large runtime overhead.  Even if
it's *small enough* you shouldn't use it (dom) just because it's
slightly easier to learn, but there might be appropriate reasons for
it depending on what you need...

Yes, for instance the fact that with DOM you can not only parse but also
build XML models in memory. I would say both are just as easy to learn,
but with DOM I can also presumably validate my document once it's in
memory. Maybe I can do that with SAX as well, not sure.

Anyways the following book has an up-to-date chapter on Java and XML

http://www.amazon.com/Beginning-Java-7-Apress/dp/1430239093/ref=sr_1_7?ie=UTF8qid=1326650427sr=8-7
even though android AFAIK uses Java 6 this reference should be good
enough for my purposes.

[android-developers] Multi Language Tool

Hi,

I need to add multi-language capabilities to an Android App I'm 
developing, and I've been thinking about building a tool to parse my 
strings.xml file, and automatically add the translations for the 
translations I want (using the Google Translate API). Anyone know if 
something like this already exists?

Thanks.

Another API for XML which I have not mentioned is StAX (the streaming API
for XML).
I guess that would be another alternative, which, presumably, being part of
java 6 also
works on android?

Android does not support StAX, last I checked. Just because something
is in Java 6 does NOT mean that Android supports it. The Android
java.* and javax.* class libraries represent a subset of Java 6 SE.

 No, Market doesn't allow that. Here's what you could do instead:

 Publish your app under the new company/package name and wait for it to be
 live. Once that's done, publish an update to your older app. That update
 should simply change the app into redirecting users to the new app on the
 Market and politely apologize for the inconvenience and ask them to remove
 the old app after installing the new one. You could also detect the old app
 when running the new one and, if found, suggest the user to uninstall it.

 You need to be careful though with the user data though. You should
 provide means for them to migrate that data from the old app to the new one
 BEFORE UNINSTALLING IT or they'll lose everything. Maybe an export/import
 procedure will do the job. If you do it right, it only takes a few seconds
 for them to export all the data from the old app and import it into the new
 one.

[android-developers] How to increase frame per second ??

hi,
I am getting frames from onPreviewFrame, compress to jpeg image
with YUV and send over the network,
but the problem is, i want to increase the frame rate. Now it is 4fps
but i want 15fps  what can i do to increase frame rate, here is my
code

public void onPreviewFrame(byte[] data, Camera camera) {


Camera.Parameters parameters = camera.getParameters();
int format = parameters.getPreviewFormat();

 //YUV formats require more conversion
if (format == ImageFormat.NV21 /*|| format ==
ImageFormat.YUY2 || format == ImageFormat.NV16*/)
{
int w = parameters.getPreviewSize().width;
int h = parameters.getPreviewSize().height;

// Get the YuV image
YuvImage yuv_image = new YuvImage(data, format, w, h,
null);
// Convert YuV to Jpeg
Rect rect = new Rect(0, 0, 320, 240);
ByteArrayOutputStream output_stream = new
ByteArrayOutputStream();
yuv_image.compressToJpeg(rect, 30, output_stream);
byte[] byt=output_stream.toByteArray();


 try {


  obj.writeObject(byt);
  obj.flush();


   // Log.d(TAG, onPictureTaken - wrote bytes:  +
data.length);
  } catch (FileNotFoundException e) { // 10
e.printStackTrace();
 } catch (IOException e) {

That is certainly not true since *every* app uses Canvas :) It depend

What it takes is:

- Extending AutoCompleteTextView or MultiAutoCompleteTextView
- Providing a suitable adapter

Take a look at the built-in Email app:

http://www.grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android-apps/2.3.7_r1/com/android/email/activity/AddressTextView.java?av=f

Or else take a look at K-9, you can also browse its source repository online.

[android-developers] Test apps with usb to phone - works if phone has bad ESN?

So far I've been testing apps during dev using emulator. I understand
I can test directly on an android phone attached by USB. I'd like to
try.

In order to get a few cheap phones for testing I am looking at used
units with bad ESN. Will they work for testing by USB to my
development PC? They won't be on any service plan and, of course, only
testing apps that run with no connection to a service.

I'm not seeing a variable name,  Is there anyway to find What variables 
or Which Bitmap this is that is 2M in size ?


Thanks again

How can I trace this to an actual  variable

Dump the heap and examine it using the Eclipse MAT plugin:

My main  concerns are the  1-byte array  esp. the 2.039 MB
I'm sure it is an Image or Bitmap  I just don't know which one

I strongly encourage you to dump the heap in Honeycomb or Ice Cream
Sandwich then, as they do a much better job than do earlier versions
of Android of reporting bitmap memory.

Re: [android-developers] Re: Android, auto complete with email contacts.

2012-01-15 Thread Kostya Vasilyev

The auto-complete list is provided by an adapter, which is responsible for:

1) Filtering
2) The drop-down list item views (sort of like with spinner and list view).

Here is the adapter from the built-in Email app:

Re: [android-developers] Re: Hardware accleration slow down every Canvas app. Why?

I think Romain Guy was looking for specific examples from the stock
Android apps.  You said that *all* apps slowed down, if some random
market app slows down, that's not really unexpected, if you can
substantiate your claim by pointing out an app running on many devices
because it comes preloaded, it might be a cause for concern.  (This is
a case where your numbers don't match their numbers, and people trust
their numbers, so your numbers are probably wrong, or your hardware is
just broken.)

 Have you tested the app to see how much noise it can tolerate? And
 have you listened to how much noise there is in actual use on the
 shortwave radio bands?

   The job of parsing Morse code can be very simple if the sound is clean
   and regular.  If it is a little bit irregular in timing, then the job
   gets harder.  If there is a little noise, then it gets harder still.
   And if there is a lot of noise, then the programming becomes nearly
   impossible.  The last I heard, a program could not beat a trained
   human listener in the toughest of environments.  So how clean and
   regular in timing is this Morse code that you want to parse.

 It would if there were an Android API for it. I am not aware of
 one,
 and I doubt one exists. This is rather a fairly simple (audio)
 signal
 processing task.
 
 What does have to do with Android is the question: how can he use
 the
 phone's microphone to listen to the sound, what APIs should he use
 to
 generate an audio stream out of it (for that signal processing)?
 The
 answer to these questions is not obvious either.

   morse
   sound to text,how to do that???
 
  Write the code to do that or use a library. This has nothing to
 do
   with
  Android specifically.

Service Actvity is not a thing - they are two separate things. Read the
documentation.

Re: [android-developers] Re: how to convert morse sound to text???

This question shouldn't be on this list.  This is a signal processing
question, and not a really simple one.. You'll need a signal and
audio processing library, which you can probably find somewhere. The
Android part of this question is how you get the audio, but actually
processing it and detecting the morse code is nontrivial.. I know I've
seen algorithms for doing this sort of thing in textbooks before, but
I'd guess that if you don't have a signals background it's going to
take quite a bit of work.  Perhaps try an amateur EE forum?

 Have you tested the app to see how much noise it can tolerate? And
 have you listened to how much noise there is in actual use on the
 shortwave radio bands?

   The job of parsing Morse code can be very simple if the sound is clean
   and regular.  If it is a little bit irregular in timing, then the job
   gets harder.  If there is a little noise, then it gets harder still.
   And if there is a lot of noise, then the programming becomes nearly
   impossible.  The last I heard, a program could not beat a trained
   human listener in the toughest of environments.  So how clean and
   regular in timing is this Morse code that you want to parse.

 It would if there were an Android API for it. I am not aware of
 one,
 and I doubt one exists. This is rather a fairly simple (audio)
 signal
 processing task.
 
 What does have to do with Android is the question: how can he use
 the
 phone's microphone to listen to the sound, what APIs should he use
 to
 generate an audio stream out of it (for that signal processing)?
 The
 answer to these questions is not obvious either.
