[android-developers] Re: Android DOM implementation issues

[Mariano Kamp]

So what is it you're asking for DOM or SAX?
Android uses standard classes for both cases. Maybe you should run your
samples on a standard sdk  just for comparison?

startElement() is SAX, not DOM.

I also don't get the major issue. In XML attributes cannot have children. So
you probably mean something else, but I didn't get that.

[android-developers] Re: How to solve "G1/HTC Magic not recognized by ADB under Windows"

[Al Sutton]

Oh my snakes on a plane... it's working... it's actually working!

OK, here are the things I did;

1) With the g1 *not* connected, I used the MS knowledgebase article 
(http://support.microsoft.com/kb/241257) to remove the device and selected the 
"Remove drivers for this device" checkbox for the ADB bridge driver.

2) Turned off auto driver updates (Right click on my computer, select 
properties, then System protection (on the left), then the hardware tab, then 
the "Windows Update Driver Settings" button, then selected "Ask me each time I 
connect a new device before checking for drivers", the Click OK).

3) Fired up the G1, made sure the "USB debugging" was on and "Stay away" was on 
as well.

4) While the screen was still active (i.e. not gone into lock or sleep), 
connected the G1.

5) Hey presto... the device is now there :) :) :).

Thanks to everyone who helped fix this.

Al.

I had exactly the same problem on vista, it's not possible to delete
the keys.
What I did was open the device manager in control panel and then turn
on "show all devices" or something like that. I don't have vista handy
so can't fine the exact option but it's on one of the menus.

Then I uninstalled any devices that looked like it belonged to the
phone. I had tried this before but without the option to show
everything turned on and likely missed some. Uninstalling the device
removes the entries in the registry so you can see when it has worked.
Clearly uninstalling random devices isn't the best idea so be careful.

[android-developers] Android DOM implementation issues

[Jason Proctor]

thanks for the response.

i use the standard (javax.xml.parser.*) SAX parser. it tells me when 
things happen so i can build a DOM tree. so in a sense, i'm using 
both.

Android might use standard *interfaces* for the parser and DOM 
classes, but the actual implementations are different.

i developed my application against various DOM implementations, right 
now with JDK 1.5 on MacOS X. this is how i know that the Android ones 
are different.

in the DOM, attribute values are implemented as child Nodes of Attr. 
this is standard DOM behaviour.

another issue i'm seeing is that the Document class, at least, does 
not allow its child nodes to be removed.

and another issue i'm seeing is that the error messages on DOM errors 
are nonexistent - i have to compare DOMException.code against each 
possible value to find out what happened. other implementations give 
me chapter and verse.

which DOM implementation is Android using?

thanks
j

[android-developers] Re: Android DOM implementation issues

[Mariano Kamp]

A DOM parser uses SAX to built up the tree, but you don't have to do that
yourself.


DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = dbf.newDocumentBuilder();

Document d = builder.parse(new InputSource(Your Input Stream /
Reader / Whatever goes here));

Depends on what you're asking for. Mostly the apache stuff.

[android-developers] Android DOM implementation issues

[Jason Proctor]

i would say it that a SAX parser uses DOM to build the tree :-)

i'm doing it the long way round largely because i want to do some 
preprocessing on the text before i make Text nodes. but the tree that 
i make and the tree that the document builder makes should be 
essentially the same.

however, some of the differences are with DOM behaviour after the 
tree is built, eg Document throwing if i try to remove one of its 
children.

Android uses Xerces? that's what i'm using with the Mac JDK, so i 
would expect the behaviour to be the same. but it isn't, strangely. 
can you provide more detail?

thanks,
j

[android-developers] Re: Puzzled by soft keyboard

[blindfold]

Thank you, Dianne. I must admit that I find this an utterly confusing
paradigm. So now we have a *software* keyboard that makes a (novel!)
distinction between what *it* considers "physical" keys and "non-
physical" keys? All those digit and letter keys were physical enough
on my ADP slide-out keyboard, and my EditText onKey() example works
perfectly fine there with both digits *and* letters. As a physicist I
am lost here. The user sees either a (truly) physical keyboard or an
on-screen keyboard that gets physically touched, and why must there be
a further split in key types for application programmers? This
artificial split does not even match the non-Qwerty "numeric" keyboard
of basic phones, because for instance the '#' hash/pound key also
fails to raise a key event with the soft keyboard. In short, it all
looks like a design oversight to me.

To be concrete:

With the ADP slide-out keyboard, pressing '7' gives keyCode 14, and
pressing 'a' gives keyCode 29 in my example code. However, with the
ADP soft keyboard, pressing '7' gives keyCode 14, but pressing 'a'
gives... nothing, zilch, no key event at all.

I may be naive but I find this an undesirable complication. IMO I
should not have to add any special InputConnection code to recover
proper default behavior here?

Thanks

No, not Xerces.I don't remember exactly, I think there is
org.apache.harmony.something stuff and kxml.

Yeah, I could dig it up, but you could probably too. You are at your
machine? Try
someNodeOrWhateverRelevantInstanceYouHaveInYourHand.getClass().getName().

[android-developers] Messaging between 2 threads

[Latha Shivanna]

Hi All

I am writing an application in which i need to handle messages between the
main thread(the deafult UI related thread) and the user created Gamethread.

The requirement is like this.

An activity(say "Activity_X") is setting the view by "setContentView(some
"View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and
"onOptionsItemSelected()" fucntions for creating menus & a switch case for
action to be taken on selecting those menus.Menu has items like
"resume/pause/zoom/" .


All action to be take on selecting these menus are implemented in "View_Y"
in a separate Gamethread by extending "Thread" class.

So whenever a menu is selected in "Activity_X" i need to send a message to
"View_Y". And on receiving this ,a particular action/method should be called
in View_Y(GameThread).

How can i achieve this using Handlers?Is there any other way of doing this?
Please do share with me some code snippets for these.
Your advises are highly appreciable. Thank you for your time.

[android-developers] play sound issue

[Sukitha Udugamasooriya]

Hi,

In my application i'm playing a 1 second sound clip when the user
clicks on a button. after that a mall thread sleep then i have
assigned a small animation to the particular button. (500ms
duration).
Animation works fine without sound. But when I put sound the animation
is not consistent.

Why is that?

mp = MediaPlayer.create(this, R.raw.over);
try {
mp.prepare();
} catch (IOException e) {
Log.w("EXCEPTION", "IO");
e.printStackTrace();
}

Do i need to start sound on  a different thread?
Is there anything to concern regarding this?

Thanks for the help

(some "View_Y")". In "Activity_X" i have implemeted
"onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for
creating menus & a switch case for action to be taken on selecting
those menus.Menu has items like "resume/pause/zoom/" .


All action to be take on selecting these menus are implemented in
"View_Y" in a separate Gamethread by extending "Thread" class.

So whenever a menu is selected in "Activity_X" i need to send a
message to "View_Y". And on receiving this ,a particular action/method
should be called in View_Y(GameThread).

How can i achieve this using Handlers?Is there any other way of doing
this? Please do share with me some code snippets for these.
Your advises are highly appreciable. Thank you for your time.

[android-developers] Update View after OnTouch, does not work?!?

[guruk]

Hi, hope you can help:

I have :

1. private static class SampleView extends View implements
OnGestureListener { //init variables }
2. public SampleView(Context context) { super(context); buildPoints
();}
3. @Overrideprotected void onDraw(Canvas canvas) {  paintchart
(canvas,param); }
4. public void paintchart(Canvas canvaschart, int param) { // drawing
my chart }

my GestureListener Methods:
- public boolean onTouchEvent(MotionEvent me) {
- public boolean onScroll(MotionEvent e1, MotionEvent e2, float
distanceX, float distanceY) {
- public boolean dispatchTouchEvent(MotionEvent me) {

It works fine for all calculations. When I scroll I even get the right
data in my PainChart(canvas)
But the Display come NOT updated?? Why.

When I call the paintchart from OnDraw() with different Params it
works fine.
But when it come called from onScroll or even direct just for test in
onTouchEvent, it does not update
my View... ??

Any Ideas

Thanks and wish you all the best
Chris

[android-developers] Re: Update View after OnTouch, does not work?!?

[Romain Guy]

Because you cannot call the draw methods directly. You must call
invalidate(), this will cause onDraw() to be executed.

[android-developers] Re: Running exclusively SmallTests

Hey,

Just wondering if anyone has found a way to pass the command line parameter
'-e size small' to the Android JUnit test runner as configured through
eclipse. I'd rather work within eclipse than on the command line if
possible.

Cheers,

Gav

[android-developers] Re: Puzzled by soft keyboard

[Dianne Hackborn]

It's not a software keyboard, it is an IME with a rich editing interface
back to the text editor, including things like showing candidates,
performing replacement, etc.  For example, as you enter a word, each key you
enter is actually the IME delivering to the editor a  new candidate text
string to replace the one currently displayed.  This is actually a pretty
typical IME interface.

It is certainly not a design oversight...  though you can simply not give
the IME an InputConnection, in which case it falls back on delivering raw
key events (when it can...  for some characters it simply won't be able to)
and gives the user a crummy editing experience.

[android-developers] Camera preview zoom?

[moa]

Currently the camera performs previews of the shot at 480x320 allowing
for real time processing.

Is it possible define what part of full 1536x2024 camera image is used
for the smaller preview image? Basically some kind of zoom?

I am trying to get a more detailed part of the image, without have to
do a full camera acquire and crop that.

AlarmManager can handle that.

How much memory do you have?

No you don't.

You need one periodic alarm for every 24 hours. You then need zero or more
other alarms to cover the specific events that need to fire at specific
times within the current day.

[android-developers] Re: Converting bitmap to grayscale

[moa]

Actually figured it out in the end! :)


Bitmap bm = Bitmap.createBitmap(500, 500,
Bitmap.Config.RGB_565);
Canvas c = new Canvas(bm);
Paint paint = new Paint();
ColorMatrix cm = new ColorMatrix();
cm.setSaturation(0);
ColorMatrixColorFilter f = new ColorMatrixColorFilter
(cm);
paint.setColorFilter(f);
int xo = (w-500)/2;
int yo = (h-500)/2;
c.drawBitmap(bmp, -xo, -yo, paint);
bmp.recycle();

Cheers.

[android-developers] showDialog and dismissDialog behave strangely when changing orientation

[idev]

Hi
I am using the showDialog and dismissDialog methods to show progress
dialogs in my app. Moved from creating the dialog and calling show()
on it to using this in order to save state when changing orientation.
But when I change the orientation from portrait->landscape->portrait,
the dismissDialog method call no longer dismisses the dialog. The
dialog stay there all the time and I need to press the back button for
it to disappear.
To overcome this issue, I tried adding a removeDialog in onDestroy so
that the dialog is not created/displayed twice and before orientation
change, the dialog is removed. Tried adding log statements and this is
what happens
05-21 12:35:14.064: DEBUG/MyClass(193): *callingShowDialog
05-21 12:35:14.064: DEBUG/MyClass(193): *onCreareDialog

05-21 12:35:15.385: DEBUG/MyClass(193):
*onSaveInstanceState
05-21 12:35:15.415: DEBUG/MyClass(193): *onDestroy

05-21 12:35:15.585: DEBUG/MyClass(193): *callingShowDialog
05-21 12:35:15.585: DEBUG/MyClass(193): *onCreareDialog
05-21 12:35:15.715: DEBUG/MyClass(193): *onCreareDialog
05-21 12:35:17.214: DEBUG/MyClass(193):
*onSaveInstanceState
05-21 12:35:17.214: DEBUG/MyClass(193): *onDestroy

05-21 12:35:17.275: ERROR/WindowManager(193):
android.view.WindowLeaked: Activity com.android.MyClass has leaked
window com.android.internal.policy.impl.phonewindow$decorv...@43362088
that was originally added here
Some error statements
05-21 12:35:17.395: DEBUG/MyClass(193): *callingShowDialog
05-21 12:35:17.395: DEBUG/MyClass(193): *onCreareDialog
05-21 12:35:17.475: DEBUG/MyClass(193): *onCreareDialog

Initially when the activity is displayed, the onCreateDialog is called
once and on changing the orientation, onSaveInstanceState and
onDestroy are called.
But after that, onCreateDialog is called twice (once by a call to
showDialog which I make, but why the 2nd time?) and this happens every
time I change the orientation hence forth.
Any idea why that happens?
Thanks

[android-developers] How to display list of images in ListView in android?

[Vincent Tsao]

i would be retrieving values from sqlite database and have to display

[android-developers] onTouchEvent dont start onScroll!?

[guruk]

Hi again :)

I have a GestureListener and while it works perfect in another app of
mine within an extends Activity
I have problem now within an extends View.

public boolean onTouchEvent(MotionEvent me) {   return
gestureScanner.onTouchEvent(me);}
@Override   public boolean dispatchTouchEvent(MotionEvent me) {
gestureScanner.onTouchEvent(me);return super.dispatchTouchEvent(me);}
@Override public boolean onScroll(MotionEvent e1, MotionEvent e2,
float distanceX, float distanceY) {  /* some calculation here */
return false;}

It jumps first in the dispatchTouchEvent, than onTouchEvent .. but
never in onScroll?!

Only when I make explicit "return true" in onTouchEvent. But that
brings other mess, because onScroll comes now to often called.

What could be the Problem (as it works fine that way in my app in
extends Activity?

Thanks always for your help...

Chris

[android-developers] Re: Puzzled by soft keyboard

[blindfold]

OK Dianne, thank you for highlighting that the soft keyboard is not a
software keyboard. For me that is a novel insight, as I had hoped and
expected that the IME was (also, at the very least) meant to simply
emulate a software keyboard. Apparently it acts more like a newly
defined virtual input peripheral then. Indeed a paradigm shift for me,
as I simply want to keep on responding to individual key presses and
nothing else.

It would be absolutely fabulous to find some minimal example code of
how to do just that - and only that - with the IME. The soft keyboard
SDK sample is rather intimidating with its hundreds of lines of code
for a rich editing interface, making it hard to extract minimum code
as needed for just capturing individual key presses. I think other
developers would also appreciate this.

Thanks!

At the risk of sounding impertinent: why?

I can see wanting to handle key events outside an EditText, but inside an
EditText, there may be better ways of achieving your application goals
than detecting individual key events.

Part of the problem is that you have given us a very narrow view on what
you are trying to achieve. What sorts of key events are you trying to trap
and what behavior are you trying to do when those events are raised?
Perhaps by giving people a broader perspective on what you are aiming for,
you can get answers that meet your user experience objectives while also
integrate well with the IMEs.

[android-developers] Re: How to track down: java.lang.IllegalArgumentException: View not attached to window manager

[Mariano Kamp]

Hey Alex,
  thanks for showing an interest ;-)

  I don't have a reference to the dialog. I just use managed dialogs
(showDialog/dimissDialog).

  I guess the solution is to make my error reporter ignore this exception.
It's a bit lame though.

  Also I have half a dozen different stacktraces that show errors where my
app's code is not part of the stacktrace. And it's really hard to debug that
as I have the feeling that also for Cupcake I can't be sure from what
sources the release is built and the line numbers in the stacktrace aren't
that helpful then.

  It doesn't help that some of the stacktraces just show up on Cupcake
builds ;-(

Cheers,
Mariano

[android-developers] Re: Puzzled by soft keyboard

[blindfold]

Hi Mark,

> At the risk of sounding impertinent: why?

My app is aimed at blind users, and individual key presses form a
basic means to quickly change operating mode during mobile use, such
as to select a color filter by pressing the first character of the
color name, or toggle the color identifier, while also speaking the
pressed key name for confirmation. Works fine with the G1 hardware
keyboard. One does not want to enter complete strings for such quick
mode changes, nor navigate a menu (too slow, too inconvenient). Touch
gestures might make an alternative, but for consistency, and because I
already use touch for other input functions, I just want to emulate
the functionality of phones that have a hardware keyboard, and thus
respond to individual key presses on the soft keyboard. I now added a
"dummy" EditText to my app's main screen as a means for the blind user
to pop up the soft keyboard and perform a key press, but was next
baffled to find that the soft keyboard functioned as a software
keyboard for digits, but not for letters, thus breaking my app on
phones that lack a hardware keyboard. Moreover, even when entering
strings, the blind user needs speech feedback for each character
pressed, to be notified of typos. I hope this clarifies why I am
seeking a simple way to pop up the soft keyboard and get events with
individual key presses for all the keys that show up on the screen,
including all digits and letters. Hopefully such basic functionality
is possible without adding a lot of dedicated IME code? Indeed I would
not mind using a touch event to pop up the soft keyboard instead of
using an EditText, as long as I can next get those individual key
presses.

Thanks

[android-developers] How to let users send bug reports

[Michael Bollmann]

I guess most of you know the problem.
Some user got a problem and posts it at comment with no change to
reply or reach them for details.

So i wrote a class to send bug reports from within my android
application directly to my bugtracking account at http://lighthouseapp.com/.

Using it is pretty straightforward:
TicketSender.init("APIToken","AccountName",ProjectID);
TicketSender.i().send("f...@bar.com","got a problem","your app is force
closing");
TicketSender.i().deinit();

This creates a new issue that contains the users email in it's title.
APIToken can be generated at lighthouseapp.com and is used for
authentication.

If you don't know http://lighthouseapp.com/ they also got a free
account to try them.
They also integrate nicely with http://beanstalkapp.com/ for
subversion hosting which also offers a free account.

here is the source
http://pastebin.com/f36965d3a

Suggested improvements:
-make the HTTP Post request non-blocking
-attach recent logcat output to the bug report
-add an activity and make it an android library like ScoreNinja so
applications can send reports without the need of
android.permission.INTERNET

Hope you find it useful
Michael

[android-developers] Re: How to let users send bug reports

[Mariano Kamp]

Very nice.
What would be really cool if the OS would provide this kind of functionality
*and* does this in a central way, so that all bugs go through a central
instance. It would be great if the framework developers would get a feel for
how often a bug occurs. And maybe that would also lead to better code, e.g.
more assertions checked.

[android-developers] WebView.capturePicture() picture.writeToStream

[otiasj]

Hello,
I am trying to save a Picture that I got from webview.capturePicture
().

However from time to time for certain url the Picture saved is missing
some images...

I am saving/loading the Picture using writeToStream/createFromStream.

Is there any webview setting that I am missing?


here is the important part of the code :

@Override
public boolean onCreatePanelMenu(int featureId, Menu menu)
{
menu.add(Menu.NONE, 4545, 0, "load Url");
menu.add(Menu.NONE, 4546, 1, "direct display of the
picture"); //works correctly
menu.add(Menu.NONE, 4547, 1, "save pic");
menu.add(Menu.NONE, 4548, 1, "load pic"); //some images are
missing!
return true;
}

@Override
public boolean onMenuItemSelected(int featureId, MenuItem item)
{
int id = item.getItemId();
if (id == 4545)
{
webView.loadUrl("http://www.misterdonut.jp/misdoclub/
index.html");
return true;
}
if (id == 4546)
{
MyImageView img = (MyImageView)findViewById(R.id.ImageView);
Picture pic = webView.capturePicture();

//this will call canvas.drawPicture(pic) on the next ondraw
call
img.setPicture(pic);

return true;
}
if (id == 4547)
{
Picture pic = webView.capturePicture();

//save the picture to a file
OutputStream os;
try {
Log.e("WebClient", " Start saving");
os = this.openFileOutput("testPicture",
ontext.MODE_WORLD_READABLE);
pic.writeToStream(os);
os.flush();
os.close();
Log.e("WebClient", "Finished saving");
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return true;
}

if (id == 4548)
{
//load and display the picture from a file
MyImageView img = (MyImageView)findViewById(R.id.ImageView);
InputStream is;
try {
is = this.openFileInput("testPicture");
Picture pic2 = Picture.createFromStream(is);

//this will call canvas.drawPicture(pic) on the next 
ondraw
call
img.setPicture(pic2);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
return true;
}
}

Thank you for the help!!

[android-developers] Re: Removing/adding activities from/to an ActivityGroup

Just a guess. Try destroying the activity B without destroying activity A.
This may resume the activity A as soon as the activity B is destroyed.

[android-developers] Main and three binder threads are running after application close

[olko]

My application starts a remote service and binds to it. If I close the
application with the "back" button there are still some threads
running (listed in the Debug View of Eclipse) - main thread, and three
Binder threads.
In onDestroy() I call unbindService(service_connection) - is there
something else to clean up?

[android-developers] Re: RESTful user authentication

[Tom]

Hi,

I would like to know if you had some answers to your question.
I'm developping an Android application wich uses a restFul webservice
too.
The schem of the application is pretty close to yours. Indeed Android
app ask a RestFul WS (in Java RestLet) in order to communicate some
datas...
Moreover, I use Json parsing between both applications.

Had you get some others helps?

Best regards
Tom

[android-developers] Re: Removing/adding activities from/to an ActivityGroup

[Taísa Cristina]

Didn't work... if I only start B and after destroy B without destryoing A,
nothing happens to A.
But looking at TabHost implementation I could see what I was forgetting:
requestFocus!

When I request focus for B, A is automatically paused. To resume it, I start
it again (as it's a single top activity).
\o/

Thanks a lot for the attention!

[android-developers] AppWidget Updates From Service - Not Pushed to UI

[nEx.Software]

So, I have an AppWidget that  am working on and am wondering if I am
expecting something it isn't supposed to do, or if I am doing
something wrong. Basically, I have an AppWidget that spawns a
background thread to retrieve data (a la Jeff Sharkey's Sky widget)
but what I am finding is that while the phone is in "sleep" mode (the
screen is off) I am not getting any UI updates on the default home
screen. I have logging in several parts of the update service and have
confirmed that the updates themselves are being run, but when I turn
the screen back on and go the the Widget on my home screen it still
has the old data. I've tried simply waiting a little, I've tried doing
other things and then going back the the Home screen, it never updates
despite continued requests from the background thread until I manually
refresh it. My manual refresh and update service run the exact same
functions.

In my update alarm I have the following:
AlarmManager alarmManager = (AlarmManager)getSystemService
(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, (System.currentTimeMillis()
+ updateFrequency), pendingIntent);


Any help would be appreciated.

[android-developers] Re-register AlarmManager events on upgrades

[Michael Bollmann]

Dianne Hackborn said the following a while ago:
>Fwiw, cupcake will add a new field to PACKAGE_ADDED to tell you if this was
>due to an update, and allow this broadcast to be received by the app to
>restart itself.

But it still seems that the application that gets upgraded doesn't
receive this intent.

So the situation stays the same:
-you release an update
-it gets installed a few thousand time
-some users start the app manually some user do not and get mad
because the app seems not to work correctly anymore

any other reliable solutions for this?

[android-developers] Always-showing view among activities

[Taísa Cristina]

Hi all!

Is there a way to have a view "always-showing" between activities?
I say, I need a button to be always appearing on the bottom of the screen.

I could get it working with an ActivityGroup, but I got a problem. My
application can work with more than one level of activities, or rather,
Activity A can start acitivity B that can start Activity C, all them with
the button showing in the bottom. When I press "Back", I need activity C to
finish and the focus to go back to B, but as I'm using an ActivityGroup, it
does not work.

Is there another way to do that?

Thanks,

Taísa

[android-developers] Re: why 480*320 png doesn't fit on landscape full screen

[Robert Green]

It depends on your layout.  probably the parent container is what is
too small somehow.  If you try putting that image into an empty frame
or absolute layout, it'll probably fill it right up.

Check for margins, padding or other things that could make the
container in the layout be smaller than you want.  Posting the layout
would probably be helpful for us.

Thanks

[android-developers] Error retrieving a Serializable from a Bundle with a ClassLoader set

[Eborix13]

Hello,

   I'm trying to retrieve a Serializable object (Bundle.getSerializable
(String key)) from a Bundle I've constructed using the Bundle
(ClassLoader loader) constructor. While doing this I get a
ClassNotFoundException.

The comment of the Bundle constructor states: "Constructs a new,
empty Bundle that uses a specific ClassLoader for instantiating
Parcelable and Serializable objects". I've looked through the source
code of the Bundle class and I noticed that retrieving a Serializable
object executes the Bundle.unparcel() method which finally comes down
to the Parcel.readValue(ClassLoader loader). All good so far. But the
readValue method doesn't use the ClassLoader to read Serializable
objects:

   case VAL_SERIALIZABLE:
return readSerializable();

as it does when reading Parcelable objects:

  case VAL_PARCELABLE:
return readParcelable(loader);

This seems to be the cause of the error I get.

 Is the comment of the Bundle(ClassLoader loader) constructor correct
and the reading of the Serializable object is a bug? Or is the code in
the Parcel.readValue() method correct and the comment is wrong? The
comment of the Bundle.setClassLoader(ClassLoader loader) method is a
but more vague in relation to Serializable objects: "Changes the
ClassLoader this Bundle uses when instantiating objects", although it
basically sets the same ClassLoader that is set in the constructor.
So, are Serializable objects retrieved using the specified ClassLoader
or not?

Thank you...

"But I'm confident I don't deal with so much levels."
I count about 30 draw() calls on either ViewGroup or FrameLayout in
the stack.
You are dealing with quite a number of levels... probably too many of
them.

[android-developers] Re: showDialog and dismissDialog behave strangely when changing orientation

[Streets Of Boston]

Where do you call the showDialog()? In the onCreate?

(Note that there is a known issue with the onPrepareDialog that is not
called properly when a configuration change has occurred in your app.)

[android-developers] Re: Messaging between 2 threads

[Streets Of Boston]

Take a look at the OpenGL API Demo source examples. I think it's
called Kube or someting.
It provides a Game-thread that is set up to receive messages which
then can be executed synchronously on the game-thread (posting
Runnables on a queue that is managed by the Game-thread).

[android-developers] Re: showDialog and dismissDialog behave strangely when changing orientation

Not in the onCreate implementation. I am calling it on a button's  
click event. And the button is sort of a refresh button. So it might  
be pressed multiple times.

Do you have a title bar?  That takes up space.  So does the status bar
(the one that shows time, signal, battery life, notifications, etc).

I can't tell from your code snippet what you are trying to do.

[android-developers] Re: TimerTask and Views

[Streets Of Boston]

If i'm not mistaken, TimerTasks run on a thread encapsulated in a
Timer object.
Since you can't reliably call most (if not all) UI/View related
methods from any other thread than the main gui-thread, you have to
post back (using a handler) back to the main gui-thread.

I've never tried this using TimerTask, but it may work :=) :
- Create your TimerTask subclass that has access to Handler or to your
View.
- In the 'public void run' method, call post on this handler or view
to do what you want.

@Override
protected void onCreate(Bundle b) {
  ...
  ...
  final Handler handler = new Handler();
  final Runnable doUpdateView = new Runnable() {
public void run() {
  ... do something with your view ...
}
  }

  TimerTask myTimerTask = new TimerTask() {
public void run() {
handler.post(doUpdateView);
}
  }

  ...
  mTimer.scheduleAtFixedRate(myTimerTask, 0, 1000);
  ...

}

[android-developers] Re: EMMA Code coverage and JUnit

[Felipe Ramos]

Hi deeps,

I'm stuck on the point where I need to run the instrumented tests on
the emulator. I could not find a way yet to make the emulator believe
that the emma.jar is already installed on it.

Also, I don't know if there is a way of enabling EMMA instrumentation
using the SDK. I have not tried that yet. I'm using the android full
source, compiling it from scratch. I think I'm close, at least to run
it on the emulator, but on this past week I was too busy and could not
investigate more about this issue. I'm planning to put everything I
know on a blog or something like that, at least to help the other
developers that are trying to make EMMA work on Android, since I could
not find relevant references on this matter from the Google guys.

I'll send later a step by step of what I made up to now... I'm
currently at my job, so I don't have much time to write right now.

BR

You can put them in your .apk without restriction, just don't load them all

[android-developers] Re: Puzzled by soft keyboard

[Dianne Hackborn]

If you are having this text put into an EditText, there are all kinds of
APIs on that to get callbacks when the text is modified.  I would strongly
recommend using those instead of any kind of raw event interception: keep in
mind that there will be future devices with all kinds of keyboard
configurations, using various key sequences to generate the actual
characters (think 12 kit, 1/2 qwerty, etc) so unless you are using the full
key character map class you likely not work there either.

If you leave your UI without an EditText in focus, the user can long press
on the MENU key to force the soft keyboard to be displayed (or you can call
the API to show it yourself), and then you are in the situation I already
described: no InputConnection, so text coming from the IME is turned into
raw key events, with lower fidelity support of IME features, but
compatibility with existing apps that are looking for key events.

It could be that the additional StringBuilder operations for the
string concatenation affected something.  Could be that the different
text caused the layout code to behave differently.  It's likely that
you went from just barely under to just barely over.

[android-developers] Re: how can i put 15MB images in my App?

[Streets Of Boston]

There may be no restriction on any apk, but i wouldn't put them all in
one apk anyway.

Giving the fact that you can only install your app on phone-memory
(not on your SD-card), it's likely that users see the more than
15MByte size of your app and decide not to install/buy it.

Is downloading these images an option?

[android-developers] Calling an Intent the implicit way

[Claudio Veas]

Hello group:
 I`m trying to develop an application, just to test
the ability of android to call an activity with an intent based not in
the specific class name but specifying the action, category and data
information. Acording to this link

http://developer.android.com/guide/topics/intents/intents-filters.html

 only three aspects are consulted when comparing an intent object to
select the future activity to run.
I created two android projects (and two activities),  the first is the
main project who sends the request and the second can be called
directly or through the filter.
This is the call of the activity in the main project:

Intent t3 = new Intent();
t3.setAction(Intent.ACTION_EDIT);
t3.addCategory(Intent.CATEGORY_HOME);
t3.setData(Uri.parse("http://www.yahoo.com.ar";));
try{
startActivity(t3);
}catch(ActivityNotFoundException e){
e.printStackTrace();

}

This is the part of the manifest that specifies (or at least I try to
specify) in the secondary activity that it`s available to be selected
to run with that information:











I installed both separatelly and I was expecteing to see the second
activity after the called but instead I got an
ActivityNotFoundException. By the way if I comment the t3.addCategory
(Intent.CATEGORY_HOME); line and change the t3.setAction
(Intent.ACTION_EDIT); to t3.setAction(Intent.ACTION_VIEW); the browser
is executed so I think the problem is in the manifest of the second
activity.
If you know what the problem may be I ll  apreciate any comments
If you need more information to help me pls do not hesitate to ask
Thanks in Advance
Claudio

[android-developers] How to loading images (assets or resources) dynamically?

[Kim]

Hi,

How do I load the image dynamically through the code? If its unclear,
I mean, I want to load image files by name based on the condition in
the code.

If I use images as resources, the image names have to be hard coded.
This is unacceptable to me.
If I load image in a webview (with image src path dynamically), the
time it takes to load is unacceptable to me.

Can anyone suggest any other way to load the images dynamically?

Thanks much for any pointers,
Kim

[android-developers] GPS Access Question

[Phil]

Sorry if this is a stupid question- I'm still pretty new to Android
and have been completely unable to figure this out after much google
searching and hunting around in the documentation. *Note: I've been
coding in Eclipse with the Android SDK plugins, using the Google APIs
1.5 version.

I'm working on a project involving accessing the GPS, so I'm writing a
simple program that will do nothing more than access the current
location in order to familiarize myself with the GPS code.

Based on the examples I have found, I came up with the following code.

package com.example.gps;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.widget.Toast;
import android.location.Location;
import android.location.LocationManager;
import android.location.Criteria;

public class HelloGps extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Context context = getContext();

Location location = getLocation(context);

Toast.makeText(this, "Location = " + location.getLatitude() + " 
, "
+ location.getLongitude(), 0);
}

public static Location getLocation(Context context)
{
LocationManager manager = (LocationManager)
context.getSystemService(Context.LOCATION_SERVICE);
String provider = manager.getBestProvider(new Criteria(),
true);
Location location = manager.getLastKnownLocation(provider);
return location;
}
}

The issue I am having deals with the "Context context = getContext()"
line. Eclipse tells me that this is an error (but not why). It simply
tells me I should change it to getBaseContext(). If I try this, then
the program hangs. If I try removing it and running the getLocation()
function without the context thrown in there at all, as I have seen in
some other examples, then I get a similar error on the getSystemService
() function call. Eclipse tells me I should rename it, but does not
tell me why or what to.

Any help at all would be incredible, and sorry again if this is a
stupid question. Thanks!

-Phil

[android-developers] Unable to Select (check) check box in checkboxView

[Simon]

Hello,
I've got the following row xml file which consists of CheckboxView and
TextView;


http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

http://schemas.android.com/apk/res/
android"
android:id="@+id/workout_text"
android:layout_width="fill_parent"

android:layout_height="?android:attr/listPreferredItemHeight"
android:textAppearance="?android:attr/textAppearanceMedium"
android:gravity="center_vertical"

android:checkMark="?android:attr/listChoiceIndicatorMultiple"
android:paddingLeft="6dip"
android:paddingRight="6dip"
/>
http://schemas.android.com/apk/res/android";
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
 />


Following the notepad and list11.java examples, i have the following
fillData() function which creates an array adapter and sets
theListView.CHOICE_MODE_MULTIPLE;
private void fillData() {
// Get all of the exercises from the database and create the
item list
mExerciseCursor = mDbHelper.fetchAllExercise();
startManagingCursor(mExerciseCursor);

String[] from = new String[]
{ ExerciseDbAdapter.KEY_DESCRIPTION ,
ExerciseDbAdapter.KEY_STARTDATE };
int[] to = new int[] { R.id.workout_text, R.id.date_text};

// Now create an array adapter and set it to display using our
row
SimpleCursorAdapter exercises =
new SimpleCursorAdapter(this, R.layout.exercise_row,
mExerciseCursor, from, to);

setListAdapter(exercises);

final ListView listView = getListView();
listView.setItemsCanFocus(false);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}

When the app run, i'm unable to "tick" any of the check boxes... what
am i doing wrong??

thank you for your help.

[android-developers] Android G1 - Streaming WMV

[semil103]

Hello,

I would like to know if I can view streamed WMV video format using G1
device (not the developer phone).
I understand that WMV format is not included in basic Android
Supported Media Formats. But I'm interested in developing application
specific for G1 device. My hope is taken from:
http://developer.android.com/guide/appendix/media-formats.html
Here It's written that
"In addition to the core media formats supported in the Android
platform, the T-Mobile G1 also supports the formats listed below:
.
WMV Versions 7, 8 and 9. Simple profile only Windows Media Video
(.wmv)"

I just can't find the answer for that question. can anyone help me
clearing this issue so I would know if it is worthwhile to purchase G1
device?


Thanks,
Emil
