Those arguments are FLAGS. Specifying 0 (none of the flags) gives you the
default behavior, which for hiding is always. The flags are used to limit
when it hides to certain situations. If you just want to force the keyboard
to close, use hideSoftInputFromWindow(view.getWindowToken(), 0).

The long press on menu is implemented by just doing
toggleSoftInput(view.getWindowToken(), InputMethodManager.SHOW_FORCED, 0);

You probably don't want to use SHOW_FORCED yourself (this is why it isn't
the default) because that will leave the IME displayed when the user moves
to another activity (even in another application), mostly regardless of what
that application's default preference is.

Dwass, dont know if this helps, but I finally got it to work reliably
for my particular needs.

I have a dialog with a single edit, and I wanted to softkeyboard to
automatically show when the dialog was opened, and be closed when the
dialog was closed. In other words, identical behaviour to the
EditTextPreference when used in a PreferenceScreen.

In my OnCreate() I have:

InputMethodManager imm = (InputMethodManager)
SingleEditDialog.this.getContext().getSystemService
(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput
(InputMethodManager.SHOW_FORCED,InputMethodManager.HIDE_IMPLICIT_ONLY);

Which shows the keyboard when the dialog is opened. Like you, I had
trouble getting the thing to hide when I close the dialog, I tried
calling toggleSoftInput again but no amount of changing the settings
seems to work. It is not entirely clear what is going on here, and I
am not sure why there is not a .HIDE_FORCED option. It is my app, why
can't I control when the keyboard is shown?

In the end, as I only had one edit field, I was able to use another
method to hide it,

imm.hideSoftInputFromWindow(singleedittext.getWindowToken(),
0);

where singleedittext is my EditText view.

Incidentally, there doesn't appear to be a corresponding
showSoftInputForWindow() call, though, which is again odd.

Anyway, it now works perfectly. Hope this helps someone else!

Hi Dianne,

You say that the G1 has akeyboardand so the IME is not shown by
default. I don't understand that statement. Yes, the G1 has akeyboard,
but it isn't always OPEN. Especially if the device is in
portrait mode, thekeyboardis probably NEVER open. The device should
be smart enough so that it opens thekeyboardif there is nokeyboard
open. Either that, or we need a way to show thekeyboardwhen we want
to (and hide it again when we don't).

My current problem is this: When I start an activity, the first
EditText field in the layout is focused automatically, but the
softkeyboardis not automatically shown. The user must either click (with
trackball) or touch the field to open the softkeyboard. IMHO the
developer should be able to say that he wants thekeyboardshown at
this point.

Any suggestions? I've tried all the force showkeyboard suggestions
and they sometimes do work, but usually you get stuck with
thekeyboardbeing shown after you leave the field and this causes more
problems that it solves.

Thanks,

On a myTouch, since it doesn't have akeyboard, the IME will be shown

[android-developers] How to delete file when file is created by another app

2009-09-25 Thread A.TNG


Hi,

I have this problem. Two apps: app_a and service_s. Service_S creates
file in /tmp. After create this file, service_s uses
FileUtils.setPermission to change file mode to 666. Then app_a tries

files are private. One application cannot delete files which another
application creates.

Is there any way to delete this file?

[android-developers] Re: How to save a canvas to disk

2009-09-25 Thread gjs


Hi,

That is why I gave you a complete working example ( maybe try it
yourself ). But not knowing your code I could only guess about when
you would want to call the saveView() method I provided.

I guess that you would call the saveView() method when the user
requests that your KidsPaintView view should save their 'drawing'
either to a file or to set as the wallpaper.

I imagine that you would provide a menu option button, or some
touchscreen or keyboard button to allow the user to trigger that
action - when they had finished making their 'drawing'. I just used
the trackball/dpad center button as an example to demonstrate
triggering and saving the view.

In my example I used 'SomeView' to represent your KidsPaintView and
put the saveView() method in the Activity, but you could also put the
saveView() method or some equivalent code inside your KidsPaintView
view if you wish.

You should also realize that you CAN just call draw( canvas ) on your
KidsPaintView as your class extends View so it (automatically)
inherits the View.draw( canvas ) method... You just need to ensure
that you create and use a new canvas and a new bitmap when calling the
draw( canvas) method, as I said originally and demonstrated with the
code posted.

Good luck !

Regards

On Sep 25, 12:45 am, limtc thyech...@gmail.com wrote:
 Thanks!

 I think the part that I am confused is that I never used view.draw
 (canvas) code in my program so I don't know when to call it... at this
 moment, says I wanted to clear a screen, this is my code in the view:

     public void clearScreen() {
         gradient = false;
         dots.clear();
         invalidate(); // this will call the onDraw and pass in the
 canvas
     }

 so I replace invalidate() by draw(canvas)?

You would need to also set permission on the directory to 666 -- in Linux,
deleting a file is considered an operation on the directory.

Bear in mind that by doing this, any application on the system can read
and manipulate files in this directory. There is likely a more secure
means of data sharing than this that your apps can use. Or, have them both
be a single app.

[android-developers] Re: Soft Keyboard

2009-09-25 Thread tauntz

The problem with long-pressing-menu not working is this: HTC Hero. It just
does NOT work there with the default keyboard.
I got also reports about people being not able to open the virtual keyboard
on their phones - I suggested them to try long-clicking the menu (following
Romain Guys suggestions) and I thought that everything is fine - till I got
my hands on HTC Hero - you can long-press the menu for 2 days in a row - it
still does not open the virtual keyboard there.

The bottom line is that due to platform fragmentation there's no standard
way to bring up the keyboard - different platform implementations use a
totally different concept for it. If you want to support such devices, you
could detect if a device is a HTC Hero/(or some other device that does not
use long-menu-press) and if it is, then use a different layout in your app
(eg display a button that brings up the virtual keyboard). Or do some other
ugly ugly hacks (I'll burn in hell for suggesting this, right?:P)

 Thank you both for your response.

 If the application is written for Android 1.1, does this change
 anything in regards to and there is a keyboard selected and it allows
 this? I would think that in such an app, since it doesn't know about
 soft keyboards, the system soft keyboard would be selected and would
 allow this. But perhaps there is more to this. Are you possibly
 suggesting that they've installed one of the alternate keyboards? That
 would be interesting.

 Again, this works on an emulator which I've defined to have no
 keyboard, so that is encouraging. At least I think it helps to rule
 out the caveat where the app isn't consuming the event, but I will
 check this out to be sure as I do catch key events - just not long-
 press menu ones, at least not intentionally.

 I guess now I would need to know what to tell the user to look for on
 their device such that they can get this functionality to work.
 Assuming I can get them to contact me or bother to read my web site.

 Would the keyboard selected refer to the Settings | Locale  Date |
 Keyboard [Checked] option?
 And then I guess I could refer them to the keyboard settings option
 below that to investigate further.

Understood. I was just under the impression that long pressing the

http://code.google.com/p/android/issues/detail?id=3577 and
http://groups.google.com/group/android-developers/browse_thread/thread/ca26e331dce350eb/10802a8263b52c72

 Long press on menu is NOT what you should be making your users do.  
 Seriously.  It sucks.  Who would guess that is how you get to a keyboard?  
 Please give them a decent UI.

Of course it sucks - no argument against that - but IMO cluttering the
user-interface with open virtual keyboard buttons sucks even more.
What's the minimum size of an UI item that is big enough so the user
can touch this with his/her finger? 42px on a standard
Dream/Magic/Hero screen? That is almost 10% of all the screen
real-estate for an app with a titlebar (speaking of height). Or when
you'd put that option to the menu, it would still require the user to
press menu once and then go and find the open virtual keyboard item
and press it. Sucky, isn't it?

 It's easy: if there isn't a hard keyboard (which can control resource 
 selection as well as being info available in Resources.getConfiguration()), 
 then make a UI that interacts in a nice way with the soft keyboard.  Also 
 consider doing this even if there is a hard keyboard.  Like, uh, the standard 
 platform and apps do everywhere.  You -never- make people use long press on 
 menu to enter text.  Because it sucks.

Uh, are we using the same devices here? I have a Magic here and when I
want to do filtering then:
* Home launcher - no UI for opening virtual keyboard, I have to long press menu
* Contacts - no UI for opening virtual keyboard, I have to long press menu
..are there any more places where you can filter lists in built-in apps? :)


Would it be an option to not tell developers that you need to design
a separate layout for every activity that has a listview that is
filterable (beacuse well - why would you want to have this
button/menu item on devices where there's a hardware keyboard?) and to
tell device manufacturers/IME developers to follow one simple rule -
long-pressing the menu should open the virtual keyboard? That would
at least create a standardized way of opening the keyboard. Imagine if
really every app designer is going to design their apps with open
virtual keyboard buttons - what the end users will get is n+1
applications that each have this option in different places and it
looks totally different in different apps - some have it under menu -
search, some have it under menu - filter, some have it on the screen
in green, some have it orange,  some use one icon, others use a
different icon, some have it at the top of the screen, some at the
bottom.. For the user that'll be a total mess if they have to learn
how to open the keyboard for every application that they install. THAT
sucks, doesn't it?

I don't really care if it'll be long-press menu or devices start to
have a standalone open keyboard hardware button or the framework
will automatically detect open keyboard gestures or whatever. My
point is that can we please have one standard way of opening the
keyboard so the user knows that when I want to open the keyboard in
ANY application, I have to do X?
I don't want to start an argument in the style Your approach sucks
more than mine!!!, really. I just think that the current situation we
are in, sucks :)

[android-developers] Re: Now ADC2 judging has begun.

2009-09-25 Thread Che


Did anyone get a confirmation e-mail that they got pass the
application screening?

Would've been nice if we got notice about whether our applications
were accepted or rejected.

Also, did anyone notice that the ADC2 application can sometimes be a
bit of a cpu hog when running in the background? Sort of degrades the
judges' experience - especially in the case of real-time games.

With skipping allowed, do the number of votes count towards the
overall grade of an application? Playing around with the judging app,
I found myself skimming through a lot of apps just because I didn't
want to activate my gps. Different apps require different amounts of
time to judge, but I think few of us will be willing to put a large
amount of time into an app before succumbing to the thought of 'what
the next one will be like'. If the number of votes are not taken into
consideration, I foresee a large number of 'niche' apps making it
through to the next round (would an app with one five star rating in
all categories be the best?). If not, we'll see the prettier, less
time consuming, easy to jump into apps dominating. I suppose splitting
everything into 10 categories does help balance things a bit.

[android-developers] Re: Overlay class and Event Handlers

2009-09-25 Thread Neilz


Surely someone must have some experience or knowledge of this?

On Sep 23, 10:23 pm, Neilz neilhorn...@googlemail.com wrote:
 Hi all. Maybe I don't understand the concept of event handlers, but
 this doesn't seem to work the way I would expect.

 The Overlay class, and its subclass ItemizedOverlay, have a number of
 event handlers, which I've been playing around with:

     onTap(GeoPoint p, MapView mapView)
     onTap(int index)
     onTouchEvent(android.view.MotionEvent event, MapView mapView)

 Now all these events seem to work fine, individually. But if you
 implement more than one of them, only one of them works. From my
 previous experience with events (from applets etc.) I don't recall any
 restrictions on the number of events that can be handled at once.

 For me, any one of these calls doesn't really give me enough info. I
 may want to know if someone has clicked one of my overlays, but I may
 also want to know if someone has tapped elsewhere on the map. What's
 going on here, am I missing something?

 Thanks.

[android-developers] All apps are created equal; how to install/uninstall.

2009-09-25 Thread RS


Since the judging app isn't part of the firmware/system group, was
just wondering, how come the ADC2 judging app manages to install and
uninstall .. oh well, probably through market but can other apps do
the same? How?

Or is it possible only by apps that are from the same UID as the
market app?
Thought apps installed externally can't get into system group or
install permissions.

[android-developers] Weird behavior of java.util.Preferences

2009-09-25 Thread leden


Hi all!
My app needs to save its state before being killed, and since that
state is really small (one Long), I've decided to use
java.util.Preferences. I use it like the way I would be using in any
Java application (and never had problems), though I am not sure this
is the correct way here on Android platform:
private static final Preferences prefs = Preferences.userNodeForPackage
(WordChoice.class);

I update preferences in onPause() method, to ensure that data is
always persisted no matter how my app ends:
Here is that fragment of code:
protected void onPause() {
super.onPause();
prefs.putLong(currIndex, somePositiveValue);
}

Everything works perfectly on emulator, but when I install my app onto
my g1 phone, the preferences doesn't work the way they are supposed to
work - it seems that SOMETHING clears them every time my application
is killed.
Here is the example of output of my application:
(FIRST STARTUP)
no entry found for currIndex
(STOPPED)
(STARTUP)
currIndex = 25
(STOPPED)
(STARTUP)
currIndex = 83
(KILLED i.e. from ASTRO or via terminal-emulator or killed by system)
(STARTUP)
no entry found for currIndex -- what the ...??

I really don't understand this behavior. I also tried flushing the
preferences but doesn't help.
Then I changed the code in onPause() method so that it first persists
data then calls super.onPause() but then the even worse scenario
occurs - preferences are cleared on random (about 50% to be cleared)
no matter how my app ends.

Please help me by giving, I have already spend a few hours struggling
with this issue with no success.
I would be grateful if someone posted an example of how to permanently
store that a single Long and how retrieve it, so that it works when
an application is killed.

[android-developers] Re: Soft Keyboard

2009-09-25 Thread James Webster

On the Hero and I guess other Androids as well, there is the Search
hardware button. This works in Hero Contacts AND in Launcher, bringing up
the soft keyboard. Not particulary intuitive I grant you, as you tend to
look for a button to do that on screen, but it does make sense.

Of course, in Android tapping any field which would takes text input always
brings up the keyboard anyway, so it is only an issue in Hero's list apps
because there isn't a default edit field which you can tap to start typing,
and thus auto-show the keyboard.
Is it not the same on the Magic?

2009/9/25 tauntz tau...@gmail.com

At any rate, long press on menu has ALWAYS been there purely as a very
last resort for pre-1.5 apps that couldn't have been written knowing about
input methods. It is a super-sucky mechanism to get to the soft keyboard,
and anyone writing an app today really should assume it doesn't exist and
provide a decent UI as part of their app.

Understood. I was just under the impression that long pressing the
menu is the suggested way how apps should work maybe based on
http://code.google.com/p/android/issues/detail?id=3577 and

http://groups.google.com/group/android-developers/browse_thread/thread/ca26e331dce350eb/10802a8263b52c72

Long press on menu is NOT what you should be making your users do.
Seriously. It sucks. Who would guess that is how you get to a keyboard?
Please give them a decent UI.

Of course it sucks - no argument against that - but IMO cluttering the
user-interface with open virtual keyboard buttons sucks even more.
What's the minimum size of an UI item that is big enough so the user
can touch this with his/her finger? 42px on a standard
Dream/Magic/Hero screen? That is almost 10% of all the screen
real-estate for an app with a titlebar (speaking of height). Or when
you'd put that option to the menu, it would still require the user to
press menu once and then go and find the open virtual keyboard item
and press it. Sucky, isn't it?

It's easy: if there isn't a hard keyboard (which can control resource
selection as well as being info available in Resources.getConfiguration()),
then make a UI that interacts in a nice way with the soft keyboard. Also
consider doing this even if there is a hard keyboard. Like, uh, the
standard platform and apps do everywhere. You -never- make people use long
press on menu to enter text. Because it sucks.

Uh, are we using the same devices here? I have a Magic here and when I
want to do filtering then:
* Home launcher - no UI for opening virtual keyboard, I have to long press
menu
* Contacts - no UI for opening virtual keyboard, I have to long press menu
..are there any more places where you can filter lists in built-in apps? :)

Would it be an option to not tell developers that you need to design
a separate layout for every activity that has a listview that is
filterable (beacuse well - why would you want to have this
button/menu item on devices where there's a hardware keyboard?) and to

[android-developers] ACTION_NEW_OUTGOING_CALL, abort

2009-09-25 Thread Lee


Hello,

I'm interested in selectively blocking phone calls. In the docs on
this intent I see:

...for example, a parental control application might verify that the
user is authorized to place the call at that time,
...
Any BroadcastReceiver receiving this Intent *must not* abort the
broadcast.

Blocking calls using this method seems to work fine, are there ill-
effects to be expected ?

And if you don't abort the broadcast, what action is the parental
control  application mentioned first supposed  to take ?

Thanks for any hints,

[android-developers] ddms doesn't work (issue 2545)

2009-09-25 Thread Stefan


Hello,

i am developing on a Mac OS X 10.4 (german version) and with android
sdk 1.6 r1.
The emulator only receive one lat/lon-value 0.0 if i tryy to send some
a pair aof lat/lon value.

I read the issue 2545 (http://code.google.com/p/android/issues/detail?
id=2545)

So i change the following settings in the emulator (because i read in
an other thread, that only the english locale work) to:

Custom locale: en - English
Settings - Date and time: Automatic: off, Select time: GMT+01:00,
British Summer Time, Use 24-hours: on, Select date: 2009-12-31

If i send one value (lat/lon), the emulator receive 0.0 0.0 and after
that, the emulator receive no data.
I test it with german locate, too. But the same error occur. What
setting is wrong??

My gpx file, which i later want to use looks like:

[android-developers] Touchscreen support

2009-09-25 Thread Jesper Nordenberg


I'm running Android on a Beagle Board and want to add support for
input from the Xenarc 706TSA touchscreen. When I plug it in it's
identified as:

generic-usb 0003:0EEF:0001.0004: input: USB HID v2.10 Pointer [eGalax
Inc. USB TouchController] on usb-ehci-omap.0-2.3/input0

There's also an error:

drivers/hid/usbhid/hid-core.c: usb_submit_urb(ctrl) failed

When I touch the screen there seems to be some kind of response as the
focus disappears, but I cant press anything on the screen. I get touch
events when using getevent.

Can someone help?

 On the Hero and I guess other Androids as well, there is the Search
 hardware button. This works in Hero Contacts AND in Launcher, bringing up
 the soft keyboard. Not particulary intuitive I grant you, as you tend to
 look for a button to do that on screen, but it does make sense.

This brings up the global search and can not be used for filtering
ListViews in apps that use global search. (or however it is called:
http://developer.android.com/reference/android/app/Activity.html#onSearchRequested%28%29)

 Of course, in Android tapping any field which would takes text input always
 brings up the keyboard anyway, so it is only an issue in Hero's list apps
 because there isn't a default edit field which you can tap to start typing,
 and thus auto-show the keyboard.
 Is it not the same on the Magic?

The problem is that sometimes (for example filterint ListViews) you do
not have a field to focus. It's not just an issue in Heros list of
apps but it's an issue in all apps that provide filtering for their
ListViews.

[android-developers] Re: Now ADC2 judging has begun.

2009-09-25 Thread Maps.Huge.Info (Maps API Guru)


I have to agree that any complex or involved apps will not make it
with the way the judging app is written. Google should have made it so
you could keep the apps you're judging for a while at least, in some
sort of special directory, so you could use them for a few days before
deciding if they were worth it or not. Making instant decisions on how
good it is will defeat a number of well deserving apps.

On the other hand, all my entries are exactly the type that can be
easily judged in this fashion. They require no user input, no
instructions, no sign in or registration, barely any knowledge about
the actual topic and are easy to understand, so for me, the app is
slanted in my favor... Good on that but it would be better for the
developer community if this thing was written so the apps would stay
around for at least the judging period.

[android-developers] event for button on headphone chord...

okay, first a couple of gripes --

gripe 1: why oh why t-mobile/htc did you decide to make a phone with a
non-standard USB/Power connector?  I mean seriously, wth!!!  just what
the world needs, yet another frigging connector.

gripe 2: what's up with providing a multi-media phone without a
standard 2.5mm headphone jack?  it's hard to take you seriously as a
smartphone without a regular headphone jack!

now that I have those gripes out of the way :), how do you detect when
a user clicks on the button on the headphone connector.  the button on
the connector that goes from the non-standard usb plug to the female
headphone jack.

[android-developers] Re: You must supply a resource ID for a TextView

2009-09-25 Thread Marco Nelissen


So there's your problem then, probably. The adapter expects each item
to have the same items, so that it can assign the fields from your
Cursor to the corresponding items in your list item layout. In other
words, if your normal list item contains items with IDs A, B and C,
them your section list items should also have items with IDs A, B
and C, and those items should have the same type in both layouts as
well. In your case, it looks like you have a TextView with a given ID
in one layout, whereas in the other layout that same ID is either used
for something that is not a TextView, or isn't present at all.
If you need some of the items in your list to be different between
your normal and section layouts, then you should override bindView
and handle that in there.

  The stack trace and crash you're seeing indicate otherwise.
  Unless you're doing something specific in bindView, the adapter
  expects each list item layout to be the same. You are overriding
  getView and returning different kinds of views, so I would take
  another look at that, and make sure that those two kinds of views are
  compatible.

  Each list item layout is the same. it uses R.layout.cinema_row!
  The weird is it makes my list with headers (when i use
  seperatedlistadapter) and when i scroll down, it crashes and gives
  this error.
  Really will take a look at it, if not i will put my source code here!

   It fully works
   when i don't use a seperatedList adapter..
   So there is problem with this seperatedListAdapter..
   Is there another way i can use to divide my list in sections with
   headers?

  I don't know what effect you're trying to achieve, but in general you
  can override bindView and/or getView to make each item look exactly
  the way you want.

  I have a list of movies with a release date. all the movies with same
  date has to be listed under a header with date.. And every list item
  has same layout, really don't get it :(

 Every list item, including the header items? In other words: do your
 header items use the same layout as your other list items?

It is first delivered to the foreground app as a regular key event.
If the app lets it fall through, it is then broadcast as an intent so
that background apps can get it too.
This is almost impossible to get right when multiple background apps
are interested in that button, so I suggest you don't use this feature
(it *will* change in the future).

[android-developers] Display my tracks in map

2009-09-25 Thread Ken H


I really thought this would be an easy thing to do...

I've built an app, and one of the things it does is show my current
position on the little google map on the phone. I walk around it and
it shows my speed, direction and position just fine.

Now what I want to do is show my tracks. I don't want to loose any of
the dots showing where I was -- I want it paint a trail of everywhere
I go. Simple, no?

I think my problem is I don't really understand overlays. Can I re-use
an overlay? That was my first instinct...rather than clear all the old
overlays on the mapview, make a new one, stick a dot on it and place
it in the mapview I wanted to grab the current overlay and *add a new
dot to it and put it back on the mapview. But I can seem to get that
to work. Just out of curiosity I even try not clearing the old
overlays and just adding new ones...that took about two minutes the
bring the phone to its knees.

Anybody have any ideas? A direction I can be pointed in? I know this
can be done, but I've spent a week searching with no joy.

[android-developers] how to read trace file

2009-09-25 Thread Eddified


Sometimes in LogCat I'll see
Wrote stack trace to '/data/anr/traces.txt'

But when using the DDMS perspective, File Explorer View, I can't see
anything in the data directory, I'm assuming because permission
denied. Is there a way (short of rooting my ion device) to read what's
in that text file?

Is there perhaps an android app for developers that will show the
contents of the file? It would seem there would have to be some way of
reading the file without rooting the device, otherwise why does the
o.s. write it out?

How can I read this file?

[android-developers] Re: Soft Keyboard

2009-09-25 Thread Eric Carman


Tauno and everyone else, thank you for your responses here.

Tauno, I have to agree with you that while long-press menu is not
intuitively obvious, it appears to be a standard means of bringing up
the soft keyboard (when it works) and said standard should be
maintained.

After all, it would seem to me that this type of operation is provided
at the OS level and the applications should not be required to provide
their own buttons, etc. to force the thing up when it has been closed
by the user or otherwise not automatically provided. And while long-
press menu may be an ugly way to implement this feature, it has the
benefit of precedence - it was the means provided for first in
Android.

So, I think we can conclude that the Hero implementation of Android is
broken, deliberately or otherwise isn't important. The question then
is, what is a user to do on a phone that is running an Android app and
has no means to bring up the soft keyboard? So far, they've chosen to
complain about the app on the market. Which is unfortunate, because
the Android 1.1 app can't force the keyboard if it wanted to.

Now that the OS fails to provide for this functionality consistently,
it falls on the app to provide it - in my case, leaving any users of
the older OS without an update path until their service providers
provide updates. Maybe that isn't an issue, but I have no way of
knowing. I'm also not convinced that relying on an OS feature (which
hasn't been deprecated as far as I can tell) constitutes a bad UI
design.

Tauno also makes an excellent point about consistency where multiple
apps now have to implement workarounds via buttons (which eat up a lot
of screen real estate), menus (which may be full of other app specific
options, now forcing them to a more list), and graphic consistency.
Its ashamed. I would have hoped that the Android OS, when implemented
on a new device might have a set of minimum standards that they comply
with - even if it is on a voluntary basis that might earn them a
certification or something - just spit-balling here.

I really like the fact that Android has the ability to have different
input methods, that developers can build their own for general use or
specifically for use with their app. This flexibility is great and
will certainly help the OS to adapt to a number of new platforms.
However, with great power comes great responsibility. The OS needs to
make this flexibility transparent to the app. The app shouldn't care
if the input comes from a physical keyboard, a soft keyboard, a
bluetooth keyboard, or some futuristic neural implant. It should just
recognize that some key has been pressed and deal with it. Likewise,
this flexibility requires that the OS provide the means to determine
the input method by default (of course the app can override).

Any hope the Hero will be fixed - assuming the Hero implementation is
even considered broken by the vendor? What other surprises are we in
store for with the other new phones that will be released? Has anyone
seen anything resembling a consistent way for an application to handle
this in the wild?

Again, thank you for the continued discussion.

Also, I hope this doesn't sound like a rant, but rather a brain-dump -
for what its worth.

Best Regards,
Eric

[android-developers] Re: ACTION_NEW_OUTGOING_CALL, abort

Er the documentation right above and below what you quoted talks about
canceling calls:

Once the broadcast is finished, the resultData is used as the actual number
to call. If null, no call will be placed.
...

For consistency, any receiver whose purpose is to prohibit phone calls
should have a priority of 0, to ensure it will see the final phone number to
be dialed. Any receiver whose purpose is to rewrite phone numbers to be
called should have a positive priority. Negative priorities are reserved for
the system for this broadcast; using them may cause problems.

Take a look at demo apps from SDK. Some of them draw a cube. You need
to do similar thing to display a sphere. AFAIK there is no way to draw
3D sphere using some single command. You need to generate vertices,
put them in vertex buffer and call DrawArrays or DrawElements
function.

[android-developers] Device bug: Data SMS not received on Samsung Galaxy

2009-09-25 Thread whitemice


Background:A code contained in a Data SMS is required to authenticate
the MSISDN of the device running our product.

Bug: When I receive a data SMS on the Samsung Galaxy, the Intent
“android.intent.action.DATA_SMS_RECEIVED” is not thrown and the Data
SMS arrives in the Inbox as a blank text message.  Any data contained
in the Data SMS seems to be lost once it arrives in the Inbox.

I have filed this bug here:
http://code.google.com/p/android/issues/detail?id=4018

I have made a little app to test this functionality.  It detects the
MSISDN (not working on many devices) or lets you enter it, and then
send either a Data SMS or a Text Message.  The app will then display
any incoming Data or Text SMSs by the intent they throw and allow you
to interrogate the native Inbox to determine what data was saved.

[android-developers] Re: You must supply a resource ID for a TextView

2009-09-25 Thread Wouter


On 25 sep, 16:57, Marco Nelissen marc...@android.com wrote:
 So there's your problem then, probably. The adapter expects each item
 to have the same items, so that it can assign the fields from your
 Cursor to the corresponding items in your list item layout. In other
 words, if your normal list item contains items with IDs A, B and C,
 them your section list items should also have items with IDs A, B
 and C, and those items should have the same type in both layouts as
 well.

So if i understand this good if have to use the same layout file for
my header file (that only needs a TextView) and my list item (with
much more information and many TextViews and a ImageView).

My list_header.xml file is like this:

?xml version=1.0 encoding=UTF-8?
 TextView

 xmlns:android=http://schemas.android.com/apk/res/android;
 android:id=@+id/list_header_title
 android:layout_width=fill_parent
 android:layout_height=wrap_content
 android:text=header
 android:textColor=#FF
 android:gravity=center_vertical|left
android:paddingLeft=20dip

  android:background=@drawable/settings_header
 android:textAppearance=?android:attr/textAppearanceSmall
 /

I use this to set up a text for my heade. I use the
seperatedlistadapter from here:
http://jsharkey.org/blog/2008/08/18/separating-lists-with-headers-in-android-09/

In your case, it looks like you have a TextView with a given ID
 in one layout, whereas in the other layout that same ID is either used
 for something that is not a TextView, or isn't present at all.

And I don't have a textview with the same ID.

 If you need some of the items in your list to be different between
 your normal and section layouts, then you should override bindView
 and handle that in there.

And how can i do that? I now use getView to make my list items in my
custom adapter and i only do this for my seperatedlistadapter:

adapter.addSection(parsed, new cinemaAdapter(this,
R.layout.list_header, cinema));

How can i use BindView then? I will give you my source code if you
want!

   The stack trace and crash you're seeing indicate otherwise.
   Unless you're doing something specific in bindView, the adapter
   expects each list item layout to be the same. You are overriding
   getView and returning different kinds of views, so I would take
   another look at that, and make sure that those two kinds of views are
   compatible.

   Each list item layout is the same. it uses R.layout.cinema_row!
   The weird is it makes my list with headers (when i use
   seperatedlistadapter) and when i scroll down, it crashes and gives
   this error.
   Really will take a look at it, if not i will put my source code here!

It fully works
when i don't use a seperatedList adapter..
So there is problem with this seperatedListAdapter..
Is there another way i can use to divide my list in sections with
headers?

   I don't know what effect you're trying to achieve, but in general you
   can override bindView and/or getView to make each item look exactly
   the way you want.

   I have a list of movies with a release date. all the movies with same
   date has to be listed under a header with date.. And every list item
   has same layout, really don't get it :(

  Every list item, including the header items? In other words: do your
  header items use the same layout as your other list items?

[android-developers] Notification of SMS messages: android.provider.Telephony.SMS_RECEIVED

2009-09-25 Thread Tom Gibara

I have an application that registers a BroadcastReceiver for Intents
actioned android.provider.Telephony.SMS_RECEIVED. I'm, aware that this was
removed from the documentation between 0.9 and 1.0, though it has continued
to function since.
I've never been totally clear about the status of this Intent. Something
that adds to my confusion is that there is a permission called RECEIVE_SMS
which is even used as an example in the security documentation:

For example, an application that needs to monitor incoming SMS messages
would specify:

manifest xmlns:android=http://schemas.android.com/apk/res/android;
package=com.android.app.myapp 

uses-permission android:name=android.permission.RECEIVE_SMS /

/manifest

taken from http://developer.android.com/guide/topics/security/security.html

This broadcast is extremely useful for applications (and if it was removed,
I'd hope that it was replaced by something equivalent) but I dislike being
dependent upon it without knowing its future. Can anyone provide any
clarifications on its current or future status?

[android-developers] Re: Peer-to-peer phone application?

2009-09-25 Thread Roman ( T-Mobile USA)


Right now there is no real P2P possible on Android using the
official SDK APIs.

In case of Wifi there is no support of Ad-Hoc. You could try to use a
multicast approach where you try first to discover which devices are
in the WLAN. Problem with multicast/broadcast on Wifi is that your
network performance gets impacted very fast when you add the number of
clients in the network. Also the type of traffic in the WLAN
influences the throughput.

If you think about using a central server then I would not all your
setup P2P anymore.

[android-developers] Re: Problem to count number of days between Two dates...

2009-09-25 Thread Benjamin


Instead of calculating the difference based on the date (month-day-
year) you could calculate it by the difference of the time since
1.1.1970. You would use getTime() on both, then get the difference
between them. Then you can divide this by 86.400.000 (which is the
milliseconds in a day) to get the exact number of days between the two
dates.

Best regards,
Benjamin

[android-developers] Issue with adapter redrawing when GridView Item

2009-09-25 Thread Jeffrey


I'm working on a program that generates dice, lots of dice. I finally
found out how to make an adapter to display an image dynamically, but
now I have a new problem. The dice that are generated/displayed by the
Adapter change if they scroll off the screen. Basically every time
each die image moves into view it is re-randomizing what die it needs
to show. I also need it to log the die results to a separate file, but
I don't know where to stick that code, seeing as it would add dice to
the list every time a die is re-drawn.  This is my current code:


public View getView(int position, View convertView, ViewGroup parent)
{
ImageView imageView;
if (convertView == null) {
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(75,
75));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(1, 1, 1, 1);
} else {
imageView = (ImageView) convertView;
}
Random RollDie = new Random();
Die1 = RollDie.nextInt(6);
Die1Copy = Die1;
if(((Die1Copy += QuickShoot.BSFinal)  6)) {
Die1 += 6;
}
imageView.setImageResource(DieResult[Die1]);
return imageView;
}
// references to our images
private Integer[] DieResult = {
R.drawable.die1, R.drawable.die2,
R.drawable.die3, R.drawable.die4,
R.drawable.die5, R.drawable.die6,
R.drawable.die1under, R.drawable.die2under,
R.drawable.die3under, R.drawable.die4under,
R.drawable.die5under, R.drawable.die6under
};
}

If anyone knows how I can make it generate a Die for a set position
and then not redraw please let me know you will save my life!

[android-developers] Inertial Sensor on HTC Hero

2009-09-25 Thread LVMH


Hello,

I am trying to develop an indoor inertial navigation system on the HTC
hero with the built-in accelerometer and digital compass.

As far as I know about hardware, the accelerometer chip is the Bosch
Sensortec's 3-axis BMA150 and the digital compass is Asahi Kasei's
AK8973 (similar to iPhone). I am not sure about the accuracy of each
sensor but the digital compass seems to function fairly well in the
iPhone.

What I am doing is getting accelerometer samples and magnetic field
samples at the SENSOR_DELAY_FASTEST (seems to me around 10 - 20 ms per
sample)

Then I creates a threshold of ±1 m/s^2 for every output of
accelerometer to filter out which sample is gravity (9.807f). The same
is applied for output from the digital compass (with threshold of ± 5
microtesla). I intended to use this filter to provide the correct
gravity and geomagnetic field for the SensorManager.getRotationMatrix
to work correctly (I am not sure if this method would actual provide
better result).

From the rotation matrix created above, I simply use getOrientation to
get the heading (north) and convert the output from the accelerometer
from the device coordination system to the Earth's coordination system
by multiplying to the rotation matrix.

** My question **
The result I am getting is completely not usable. It seems that the
heading is very inaccurate thus making the rotation matrix
inaccurate.
Even when I applied kalman filter, the result is still far from being
usable.
I wonder if anyone has approached this problem before and if there is
some better way to do it.

Thanks,
lvmh

Hi,

  I am new to Android development. I have been searching google to add
multiple components to a View programmatically .i.e add TextField,
Button, etc one below the other.


I could only find examples where they have used XML to design the UI.
If i want to add the components programmatically how can I do that or
I will have design the UI only using the XML.

[android-developers] EditText.onKeyUp() doesn't catch all keys

2009-09-25 Thread CG


Dear all,

I'm writing a little dictionary application for Android 1.5, and I'd
like to catch the user's keystrokes in an EditText instance. The
following code recognizes all keys, which are typed in in the Android
emulator:

  new EditText(this) {
@Override
public boolean onKeyUp(final int key, final KeyEvent event) {
  Log.i(Key:, Integer.toString(key));
}
  };

..which is fine! But I open and use the soft keyboard, most input
(except for e.g. the ENTER key) is ignored. Could anyone tell me
what's the best/easiest way to identify and process these user inputs?

Thanks for your attention,
Christian

run the application, again it make an alert for location settings. I
am not able to run this application. Please help me.

Can anyone tell me is it possible to run GPS based application

[android-developers] FILL_AND_STROKE does not seem to work with rectangles!

2009-09-25 Thread Keith


I haven't posted this as a bug because it is so basic I can only think
that there must be something that I am missing.

Basically the FILL_AND_STROKE style is not respected for rectangles.

Steps to reproduce:
0. Using Cupcake 1.5 (android-sdk-mac_x86-1.5_r3) (problem occurs on
emulator and on Android G1 dev phone)
1. Create a custom view, extending/deriving from View.
2. Create an onDraw method like the following code.

@Override
protected void onDraw(final Canvas canvas)
{
super.onDraw(canvas);

final Paint paint = new Paint();
paint.setAntiAlias(true);
paint.setColor(android.graphics.Color.BLUE);
paint.setStyle(Paint.Style.FILL_AND_STROKE);
canvas.drawRect(0, 0, 100, 100, paint);
canvas.drawCircle(110 + 50, 110 + 50, 50, paint);
}

What you will see is a rectangle that is stroked but NOT filled and a
circle that is stroked AND filled appropriately.

Since this is a basic drawing operation I can only surmise that there
must be an additional step to drawing rectangles that is not
documented. I cannot seem to find any reference to this problem as an
open issue or posted anywhere.

So would someone mind pointing me at the problem? Or is it a bug that
has just somehow slipped through?

Thanks in advance for your response,

Keith

[android-developers] Re: ProgressDialog doesnt show when called...?

2009-09-25 Thread Daniele Baroncelli


 i put up the progress dialog in the onPreExecute(). the activity can
 then just call execute(), and is otherwise decoupled from the task
 entirely.

 i do all my HTTP stuff this way.


I am definitely missing somethings, as I don't understand how I can
show the progress dialog in the onPreExecute()

1) if the progress dialog is passed as a parameter to the asynctask:
how can you access that parameter from the preExecute?
as far as I understood you can access the parameters only from the
doInBackground() method

2) if the progress dialof is instantiated in the onPreExecute():
which value did you use for the context parameter required in the
costructor ProgressDialog(Context) ?

I'll be very glad to anyone who would clear these doubts out

Cheers

[android-developers] Re: Multiple Framebuffer devices(dynamically change) support for Surfaceflinger.

2009-09-25 Thread Pankaj


Hi Dianne,

We have hardware acceleration support and that supports multiple frame
buffer device display ( as we have tested it with driver test
application). but how to fit that into SurfaceFlinger is the issue.
As per our study and understanding of SurfaceFlinger we have done few
changes as below:
1: Instead of mGraphicsPlane, take array of GraphicsPlane,
mGraphicsPlane[2] //for 2 displays fb0 and fb1
2: First Initialize main display DisplayHardware by passing dpy as 0
(Modified the constructor of the Display Hardware), then secondary
DisplayHardware by passing dpy as 1.
3: From init of DisplayHardware pass dpy to EGLDisplaySurface's
mapFrameBuffer and based on dpy value open /dev/graphics/fb0 or fb1.
4: Add a new interface API to the surfaceflinger so that secondary
display could be initilized as and when required.
5: Modified the threadLoop so that each of the APIs handlePageFlip(),
handleRepaint(), unlock Clients() will be called for both displays
dpy-0 and dpy-1.

There are following issues that I am not that much clear.
1: Does we need to modify the OpenGL|ES initialization based on the
DisplayId (dpy) or it will remain same for both display?
2: Does any chnage in the libagl is required for support of multiple
frame buffer support?
3: We have kept the mWormHoleRegion separate for both GrpahicsPlane (0
and 1), so whether we require to maintain different mDirtyRegion and
mInvalidate region for both GrpahicsPlane?
4: How the Layer created on different grphics plane will be composed
to display on the same physical screen?

It will be nice if you can focus some more light on the above issues.

Thanks and Regards,
Pankaj Dubey

[android-developers] Re: ADT Eclipse Plugin: Can't install - No Repository Found

2009-09-25 Thread Sudheesh J


I faced similar issue with the ADT plugin integration with Eclipse 3.5
for Java (Galileo), behind a very restrictive proxy.
The eclipse proxy configuration also didn't help to resolve the issue.

Then I followed
 http://developer.android.com/sdk/1.6_r1/installing.html#Troubleshooting,
i.e, manually downloaded the plug in and configured it without any
issues.

Later, I tried the first method (direct update from eclipse) from a
direct connection, which was successful.

I have not tried it on Eclipse classic, but till now, I don't see any
reason why I should.

 Update: Turns out, the ADK doesn't play nice with Eclipse for Java

 Posting this for anyone else who might be Googling in search of a solution
 for this issue, as I haven't seen this distinction mentioned in any other
 threads.

  Hi All-

  I'm having a lot of difficulty installing the ADT plug in under
  Eclipse 3.5 (Galileo)... I have tried both http and https access to
  the Eclipse update site, and in both cases I get the following errors:

  An error occurred while collecting items to be installed:
  No repository found containing: binary,org.eclipse.jdt_root,
  3.5.1.r351_v20090810-0600-7r88FEoFI0WTo6Az-1qFRHm37ChJ
  (second line repeated about 20x for various missing files)

  I found a post (http://tinyurl.com/yc2cr28) where removing/re-adding
  the source URL in Eclipse is also recommended. This didn't help the
  No repository found errors.

  Has anyone else experienced/resolved this issue? I am running the
  Eclipse for Java Developers from Eclipse.org, and the Sun Java 5
  JDK.

  Thanks,
  Dave

[android-developers] Re: Adding Components Programmatically


   I am new to Android development. I have been searching google to add
 multiple components to a View programmatically .i.e add TextField,
 Button, etc one below the other.

 I could only find examples where they have used XML to design the UI.
 If i want to add the components programmatically how can I do that or
 I will have design the UI only using the XML.

Use normal constructors (e.g., new TextView(this);) and add them manually
to their containers (layout.add(textview, params);).

Bear in mind that if you do this, you will have much work in front of you
to handle:

-- screen rotations (portrait versus landscape)
-- multiple screen dimensions (QVGA, HVGA, WVGA)
-- multiple screen sizes (3, 3.5, 5)

The layout framework was designed to make it easier to swap in and out
different layouts for those different device characteristics.

[android-developers] Re: Computational cost of calling getReadableDatabase or getWriteableDatabase?

2009-09-25 Thread Marco Nelissen


Why are you calling getWriteableDatabase so often? You should only
need to call it once, and then use that database for all your
insertions.
Also, batch insert generally means you insert multiple items at
once, so you should only need to do one call to bulkInsert(), and
hence one call to getWriteableDatabase.

 I am doing a batch insert for N items and I have to call
 getWriteableDatabase method N times in my dbhelper method.
 and I find that the insertion time is slow takes  ~9 secs for 50 rows with
 ~10 columns.
 How to improve the speed of a batch insertion, or maybe calling
 getWritebableDatabase is an expensive operation time-wise?
