Every ListView item layout is separate from those next to it - 
therefore, it positions and sizes its children without any regard for 
other list items.


Two things you can try are:

- Do not try to make a table, and use multi-line layouts instead, the 
screen is typically not wide enough to fit a proper table anyway.


- For a table-like layout, position the views within your item layout so 
that they always have the same size, regardless of the data they 
contain. This can be done by using a LinearLayout, with the children 
having zero layout_width and non-zero layout_weight values.

you would a normal table on the layout:

I would like it aligned as in a html table.

Any pointers?

Re: [android-developers] Tablet support up to 2.2


Neil,

I've only done Galaxy Tab tests with the emulator as well, so my 
observations are somewhat limited, but still, here they are.


The Galaxy Tab reports itself as an HDPI device, even though its actual 
screen density is 170 dpi. This is to account for the larger display 
pixel count, and greater viewing distance.


Still, compared to a typical 4 480x800 hdpi phone screen, the Galaxy 
Tab can fit more on the screen, since it has more pixels: using a 72x72 
icon as a measurement unit, a 480x800 screen can fit 6.6 accross and 
11.11 down. The Galaxy Tab can fit 8.33 down and 14.22 across.


This makes images look *smaller relative to the rest of your layout*, 
even though they are *larger in real world units*, compared to a 4 hdpi 
phone, and have *same pixel size*.


The gist of all this is: I don't think you can expect an application 
running on the Tab to look just like it looks on a phone, only larger. 
So far, this has been the case for phones of varying screen sizes and 
densities, but for a tablet device, this is no longer true.


Now, if you want to have images in your application just for tablets, 
you can use res/drawable-large-hdpi, as phone screens are normal and 
tablet screens are large (or possibly xlarge, new in 2.3). But 
personally, I found it more useful to focus on making sure that my 
layouts can be used in landscape mode without vertical scrolling 
(sometimes creating separate -port and -land versions to achieve this).


Oh, and here is a table comparing the Tab to a 4 hdpi screen:

Pixels  Inches  DPI IconIcons/screen
480 2,06233,01  72  6,67
800 3,43233,01  72  11,11





Pixels  Inches  DPI IconIcons/screen
600 3,54169,49  72  8,33
10246,04169,49  72  14,22

26.01.2011 11:40, Neilz ?:

Hi all.

I've got the Galaxy Tab emulator running, and was curious to see how
my various apps worked regarding layouts. I've looked at the various
docs on this, but they mostly talk about version 2.3 which I'm not yet
supporting.

My apps generally currently specify:

android:minSdkVersion=3 android:targetSdkVersion=8

and I have folders for res/drawable and res/drawable-hdpi, and just
the one res/layout folder.

I notice that while the layouts fit nicely, the images are all too
small. So, bearing in mind my current spec above, what do I need to
add to make the apps compatible with tablets, without yet included 2.3
support?

Re: [android-developers] SDCard question


Scott,

You can't. Install to sd is only available if the phone is running 2.2 
(or later).


There might be custom firmwares based on earlier versions of Android 
with this function back-ported, but that's not a typical runtime 
environment.

[android-developers] SSL certificates on Android

2011-01-26 Thread Paolo

Hi there,
I'm new on SSL and I have one question for you about it on Android.
So, sorry me if I say something that isn't correct :)

I have to start a communication with a REST Web Service. There are two
steps I should clarify to myself... the second one is the most
important for my target.

1) I must be sure I'm starting to communicate with the WS. So I need
its own certificate (it is on the server side). I know how to do that
and the troubles connected to a CA or a self-signed certificate, after
reading this article: 
http://blog.antoine.li/index.php/2010/10/android-trusting-ssl-certificates/

I believe there is no problem to do that.


2) step 2 here... Now I have also the opposite problem. The WS must to
be sure to communicate with a mobile device (me) and not with other
one. To do that I need a certificate on the device embedded in the
app, in order to allow the WS to know who I am and then we can starts
the communication.

In other words... I need to know with who I'm speaking and the same is
for the WS. This is my problem. Usually only the first step is the
important one, in my case the second one is the most important.

I hope to be clear. If you have some questions o doubts, please ask
me.

Thanks to all in advance.

Paolo

a Simple Question.

I have four buttons and I am using four images for each button. is there any

You don't need to replace the image from code when the user clicks on a 
button - with a state list drawable this can be done entirely with 
resources:

[android-developers] Re: Tablet support up to 2.2

Hey thanks Kostya, that's really useful. I agree, maybe ensuring that
the layout works is more important than resizing all the images again.

Portrait vs Landscape is another issue... the majority of my apps
specify portrait only, it's just the way they were intended to work.
Do I take it that these tablets are designed to set landscape mode as
their default?

There are lots of images of the Tab being used in portrait mode, but I 
decided that landscape is important for *my* apps - as I would want to 
use a tablet in both orientations, if I had one (maybe I'm wrong about 
that, but I've already done the work).


BTW, this is what my layouts look like:

[android-developers] times_contacted not being updated on some devices

2011-01-26 Thread Mor G.

Hi,

I've noticed some strange behavior when using the times_contacted
field in ContactsContract.Contacts (and also the last_time_contacted
field).

In some Samsung devices this counter counts emails only, in some HTC
devices this is always zero, and in other HTC devices this counter is
incremented for the wrong contacts (there's a confusion between
RawContact ids and Contact ids).

Has anyone else came across this issue?
Does anyone have a suggested solution to overcome this?

I've managed to create a BroadcastReceiver that updates
times_contacted for incoming/outgoing calls, but this doesn't solve
the wrong contacts issues, and isn't as complete as the counting in
Nexus for example (on Nexus it counts calls,emails,smss), also, I
don't want to count these calls twice on devices where this counter
already works.

Any help? Any ideas?

Thanks,
Mor.

Re: [android-developers] Re: Notepad Sample - adding more columns to listview



The popup in Iridium Flares looks like a TableLayout:

http://developer.android.com/reference/android/widget/TableLayout.html

TableLayout doesn't recycle views like ListView, and so isn't really 
suited for long scrollable lists, but it's just fine for presenting 
compact data (also useful for lining up controls within a layout).

[android-developers] What colour to use for custom contentView in notification for 2.2 and 2.3

So I've got a custom view being used as a RemoteViews in a notification.

Looking in the 2.2. resource, I can see 
\layout\status_bar_latest_event_content.xml where it explicitly sets the 
colour of the title and text to ff00. Which works nicely under 2.2 
stock. The text is black.

But under 2.3, the notification bar is darker and black text is not visible. 
Looking in the same file under 2.3 I find it is now using a 
style 
android:textAppearance=@style/TextAppearance.StatusBar.EventContent.Title. 
This is using ?textColorPrimaryInverse which is white but the same value 
under 2.2 is also white.

The TextAppearance.StatusBar style hierarchy doesn't exist for 2.2 or below.

So should I check for the sdk version and if running 2.3+ then get the value 
of the style attribute and manually override the color for the custom 
view..? Seems a bit of a faff to have to do that? And how do I compile it to 
refer to that new attribute when I'm targetting 2.2? Any way to get it to 
work purely in xml with no additional java faff..?

But I'm also wondering about all that theming going on for custom roms - how 
do they handle this..? For a 2.2. phone, the text colour of black is 
hardcoded into that layout. So does that mean that no theme for a 2.2. 
device can change the colour of the notification bar background to black 
otherwise all the notifications will be unreadable? Am I missing something 
here?

Re: [android-developers] Re: a simple question (onClick)

You need one XML file with selector, and several drawable files that 
it would reference for individual states, for example, 3 PNGs or nine 
patches.

Re: [android-developers] What colour to use for custom contentView in notification for 2.2 and 2.3


H,

You can try putting a 2.3 specific layout into res/layout-v9. You'd 
then be able to use the new style, provided you build with 2.3, and 
still remain compatible with earlier versions.


-- Kostya

26.01.2011 15:42, H пишет:

So I've got a custom view being used as a RemoteViews in a notification.

Looking in the 2.2. resource, I can see 
\layout\status_bar_latest_event_content.xml where it explicitly sets 
the colour of the title and text to ff00. Which works nicely 
under 2.2 stock. The text is black.


But under 2.3, the notification bar is darker and black text is not 
visible. Looking in the same file under 2.3 I find it is now using a 
style 
android:textAppearance=@style/TextAppearance.StatusBar.EventContent.Title. 
This is using ?textColorPrimaryInverse which is white but the same 
value under 2.2 is also white.


The TextAppearance.StatusBar style hierarchy doesn't exist for 2.2 or 
below.


So should I check for the sdk version and if running 2.3+ then get the 
value of the style attribute and manually override the color for the 
custom view..? Seems a bit of a faff to have to do that? And how do I 
compile it to refer to that new attribute when I'm targetting 2.2? Any 
way to get it to work purely in xml with no additional java faff..?


But I'm also wondering about all that theming going on for custom roms 
- how do they handle this..? For a 2.2. phone, the text colour of 
black is hardcoded into that layout. So does that mean that no theme 
for a 2.2. device can change the colour of the notification bar 
background to black otherwise all the notifications will be 
unreadable? Am I missing something here?

Hi Kostya, cunning idea!

I've not made the leap to building against 2.3 yet as I like to see all the 
source code - plus there isn't a working 2.3 emulator with lvl support yet. 
Maybe this is the final reason...?

But surely there must be a better way to not have to resort to layouts for

[android-developers] Query in calling SOAP based web service in Android

2011-01-26 Thread Nandlal Viranni

Hi All ,

I am new to Android .

I am developing one application .

In which , i need to use SOAP based web service.

but i am not able to do this task .

I need to pass class object as a argumens while calling web service
method .
And I am getting error regarding Serialize .

Now , I change the way of calling web service and

I want to pass xml data as a argumens ..

Is there any solution for this problem ???

Is there any relavant link ??

thanks  Regards

Re: [android-developers] What colour to use for custom contentView in notification for 2.2 and 2.3

Every time the SDK gets a new feature, using it requires building with 
the new version.


I don't see anything wrong with that (think alternate drawables in 1.6, 
install to sd in 2.2).


As for the alternate layout - 2.3 seems to have received some minor but 
probably important UI tweaks: in addition to the issue at hand, status 
bar icons for notifications have a new look, different from 2.2 and below.


http://developer.android.com/guide/practices/ui_guidelines/icon_design_status_bar.html

I would look at it this way: it's the price you pay for making your 
application look its best on all platform versions. Takes some work, but 
then what doesn't?


YMMV

Yes, I looked all over that code and even down into AsbListView.
It actually registers an internal instance member with the adapter,
and the notify call does seem to make it to the observer as far as I
can see, but there doesn't seem to be any code that connected the
observer and the ListView.

I was digging down that far in the first place because I was sure
(three times over, I rewrote it from scratch three times using
different examples and tutorials besides my first attempt from memory)
that I had correctly implemented the Adapter and set it on the
ListView. The list view simply never called the adapter after the
notify method was called. I know that because I used the basic print-
to-log when called technique of tracing the calls. The Adapter would
get properly called when first set on the ListView but after that no
amount of data change and notify calls would cause it to re-read the
adapter, which is what I expect it to do if I notify it that my data
has changed.

I the end I simply created a new adapter and reset it on the ListView,
which seems to be working, however that's broken IMO.

I think the next step should be that I write up a quick demo app that
attempts replicate the problem. If it doesn't do anything except
demonstrate what I'm seeing, then it should allow others to test as
well.
I'll see if I can make time tomorrow for that.

BTW - That link seems to not be visible to me :) must be on your
internal network.

  ListView with a custom adapter based on BaseAdapter.

  The problem is that updating the data and calling

  I have modified the adapter so that ever method that is called in
  it
prints
  itself to the console.

  my adapter has a method that does the update of the contents and
attempts
  to notify:

  public void updateData(ListEvent data) {

   this.data.clear();

   this.data.addAll(data);

   notifyDataSetChanged();

  }

  The problem is that after notifyDataSetChanged() is called, the
  list
never
  calls any other methods, not even getCount().

  My data has changed, and i've notified ListView that it has, yet it
still
  refuses to update.

  After some investigation in the OS source, I don't see where the
observer
  in the list actually tells the list to update.

  It seems the only way to get the list to update its elements is to
re-set
  the adapter on it with the new element set.

  Now I've seen many threads in the group saying that they user was
  doing
  something wrong... but I don't see how the notify is going to
  update
the

  So, I think i'm dealing with a bug here.

  Can someone actually find the code that does the update in the
  ListVIew
  when adapters notifyDataSetChanged() is called?

[android-developers] Communicating between two devices directly

Hi,

I'm in need of communicating between two devices over WiFi directly,
w/o need of AP. As far as I know adhoc mode
is not supported oficially (unless you apply some unofficial patches
to wpa_suplicant) but maybe I miss something
and certain version of Android  going to officially support adhoc?
Anyway, I am open for any hints of solution I could
use to get this done (BT is out of question due to limited range. At
worst I can use client-server architecture but
I would like to avoid this as it requires data plan and/or carrier coverage)

Re: [android-developers] Communicating between two devices directly


Marcin,

You're right about ad-hoc (ibss) networking not being supported:

http://code.google.com/p/android/issues/detail?id=82

Still, if you've got phones that are connected to the same WiFi router 
(or to different routers that are connected to one another, probably 
common in an office environment), then you should be able to get TCP/IP 
connections between phones that bypass the cellular network and go over 
WiFi.

H,

More on sources in Eclipse - I just set it up so that the debugger finds 
a different version of Android sources from the one used for building.


In my case, I am building with 2.2, debugging on 2.1update1.

This is something I've been wanting to solve for some time, the email

Re: [android-developers] What colour to use for custom contentView in notification for 2.2 and 2.3

Yeah, that would be good.

My concern with building against 2.3 was that if I debug'd, I would need to 
use a 2.3 emulator. And with the broken lvl in it, I would have to hack my 
app heavily and then couldn't rely on the testing anyway. So the ability to 
build against 2.3 but debug against 2.2 or 2.1 would fill that gap nicely.

Good work!

Re: [android-developers] Communicating between two devices directly


What mode does 2.2 use for WiFi tethering?

If it's not ad-hoc, but rather full AP mode, then this might be a 
workable solution (with some complications, like tethering can only be 
enabled by the user at this time, and it's not a true peer-2-peer solution).


Limiting your app to 2.2 is probably going to give you a broader reach 
than limiting to rooted devices.

Re: [android-developers] Re: a simple question (onClick)

You don't have to put UI states and the image that makes it different 
from other buttons into the same drawable / image.


ImageButton can use two separate images: one is android:background and 
one is android:src. If you provide UI state feedback with one (the 
background), you can use a simple .png image for the other (the src 
one) to make buttons look different.


There is also a LayerList drawable that can combine multiple drawables 
into one, this might work too (although I haven't used it):

Re: [android-developers] Tablet support up to 2.2

I think you should try to avoid the situation where images mismatch between
the layout.

I'm not entirely sure in what scenario you are seeing this, but for many
uses of issues it should not be an issue, any more than say text looks
smaller than layout.  For example an image that is the frame of a button or
a check box or a lock or other icon: it just doesn't make sense of such an
image to grow in size just because there is more room for your layout.

The main place I see people having such an issue is when they use an image
as a background, which I think because of the variety of screen sizes just
ends up being fundamentally problematic on Android.  Best is to simply avoid
this, like the standard Android UI does.  (And note having a background
image has another big advantage: on most devices you can do 60fps scrolling
in a list view and such when on a solid color; if you put your content on
top of an image, there are very few devices that will still give you 60fps
scrolling.  It causes a huge performance hit, both to fill the background
with the image, and because the content on top now needs to be blended with
it.)

If you absolutely want a background image to give your app more style, there
are a couple ways you can do this: (a) use an abstract design, so you can
scale the image to fit the screen you are running on (and be sure you
pre-generate the scaled image at first layout or draw, or your frame rate
will totally go in the dumper); or (b) use a 9-patch image that does some
more intelligent scaling (though if the scaled parts are not a solid color,
this is still drawing a scaled image, so if you just directly draw the
9-patch you have the same significant performance hit).

  Neil,

 I've only done Galaxy Tab tests with the emulator as well, so my
 observations are somewhat limited, but still, here they are.

 The Galaxy Tab reports itself as an HDPI device, even though its actual
 screen density is 170 dpi. This is to account for the larger display pixel
 count, and greater viewing distance.

 Still, compared to a typical 4 480x800 hdpi phone screen, the Galaxy Tab
 can fit more on the screen, since it has more pixels: using a 72x72 icon as
 a measurement unit, a 480x800 screen can fit 6.6 accross and 11.11 down. The
 Galaxy Tab can fit 8.33 down and 14.22 across.

 This makes images look *smaller relative to the rest of your layout*, even
 though they are *larger in real world units*, compared to a 4 hdpi phone,
 and have *same pixel size*.

 The gist of all this is: I don't think you can expect an application
 running on the Tab to look just like it looks on a phone, only larger. So
 far, this has been the case for phones of varying screen sizes and
 densities, but for a tablet device, this is no longer true.

 Now, if you want to have images in your application just for tablets, you
 can use res/drawable-large-hdpi, as phone screens are normal and tablet
 screens are large (or possibly xlarge, new in 2.3). But personally, I
 found it more useful to focus on making sure that my layouts can be used in
 landscape mode without vertical scrolling (sometimes creating separate -port
 and -land versions to achieve this).

 Oh, and here is a table comparing the Tab to a 4 hdpi screen:

 Pixels Inches DPI Icon Icons/screen  480 2,06 233,01 72 6,67  800 3,43
 233,01 72 11,11




   Pixels Inches DPI Icon Icons/screen  600 3,54 169,49 72 8,33  1024 6,04
 169,49 72 14,22

 Hi all.

 I've got the Galaxy Tab emulator running, and was curious to see how
 my various apps worked regarding layouts. I've looked at the various
 docs on this, but they mostly talk about version 2.3 which I'm not yet
 supporting.

 My apps generally currently specify:

 android:minSdkVersion=3 android:targetSdkVersion=8

 and I have folders for res/drawable and res/drawable-hdpi, and just
 the one res/layout folder.

 I notice that while the layouts fit nicely, the images are all too
 small. So, bearing in mind my current spec above, what do I need to
 add to make the apps compatible with tablets, without yet included 2.3
 support?

 I was digging down that far in the first place because I was sure
 (three times over, I rewrote it from scratch three times using

 that I had correctly implemented the Adapter and set it on the
 ListView. The list view simply never called the adapter after the
 notify method was called. I know that because I used the basic

 would
 get properly called when first set on the ListView but after that
 no
 amount of data change and notify calls would cause it to re-read
 the
 adapter, which is what I expect it to do if I notify it that my
 data
 has changed.
 
 I the end I simply created a new adapter and reset it on the
 ListView,
 which seems to be working, however that's broken IMO.
 
 I think the next step should be that I write up a quick demo app
 that
 attempts replicate the problem. If it doesn't do anything except
 demonstrate what I'm seeing, then it should allow others to test as
 well.
 I'll see if I can make time tomorrow for that.

Re: [android-developers] What colour to use for custom contentView in notification for 2.2 and 2.3

You should design your notification icons to work well against any
background.

When we changed the status bar background to black, we were planning on
implementing compatibility for old apps that assumed the old background,
like we usually do.  However we realized that since there have already been
devices shipping with a black background from various vendors, it wouldn't
really help -- developers already unfortunately were in the boat where they
had to deal with making their icons work on both light and dark backgrounds.

So just design your icons to work on both.  The simplest way would be to do
something like put a black background behind them, perhaps a rounded
rectangle.

 My concern with building against 2.3 was that if I debug'd, I would need to

 build against 2.3 but debug against 2.2 or 2.1 would fill that gap nicely.

 Good work!

[android-developers] Re: Handling touch events for dragging content when changing the orientation of the screen

2011-01-26 Thread JAlexoid (Aleksandr Panzin)

You have to rotate the drag direction vector as well as canvas.
Even without looking at your code, the actual drawing code probably
doesn't translate the dragging direction in accordance with the
direction of the device.

On 26 янв, 08:13, Dave Bryson debry...@gmail.com wrote:
 I have a map application using an in-house map engine on Android. I'm
 working on a rotating Map view that rotates the map based on the
 phone's orientation using the Sensor Service. All works fine with the
 exception of dragging the map when the phone is pointing other than
 North. For example, if the phone is facing West, dragging the Map up
 still moves the Map to the South versus East as would be expected.  I
 assume translating the canvas is one possible solution but I'm
 honestly not sure the correct way to do this to swap the axes without
 disrupting the coordinate system needed by the map tiles.

 Here is the code I'm using to rotate the Canvas:

 public void dispatchDraw(Canvas canvas)
 {
     canvas.save(Canvas.MATRIX_SAVE_FLAG);
     // mHeading is the orientation from the Sensor
     canvas.rotate(-mHeading, origin[X],origin[Y]);

     mCanvas.delegate = canvas;
     super.dispatchDraw(mCanvas);
     canvas.restore();

 }

 What is the best approach to make dragging the map consistent
 regardless of the phones orientation? The sensormanager has a
 remapcoordinates() method but it's not clear to me exactly how to
 use it.  I've searched the web and posted to StackOverflow to try and
 figure this out...no luck so far.  Any pointers would be greatly
 appreciated!  Thanks.

Thought about that too, yet need to do some testing.

 If it's not ad-hoc, but rather full AP mode, then this might be a workable
 solution (with some complications, like tethering can only be enabled by the
 user at this time, and it's not a true peer-2-peer solution).

 Limiting your app to 2.2 is probably going to give you a broader reach than

Thanks Dianne. I wasn't too worried about the icon as I can deal with that - 
it was the colour of the text to display by the side of it in the 
contentView. But you mentioned the same thing that I was realising: custom 
Themes must have broken this a long time ago anyway so there are probably 
many apps out there on gingerbread with black text on a black background in

[android-developers] Built-in resource unexpectedly not found

It happened on a Motorola Milestone which appears to be using official

The resource in question refers to a built-in Android resource which

Clearly this is not a programming error but something else.

[android-developers] performance when passing background data to ui thread

2011-01-26 Thread neuron

Hi

I've got an app that spawns of a seperate thread. Parses JSON data into a 
structure. And passes it back to the main thread through a handler. Each 
part of data is sent through the handler individually. That worked fairly 
well with my previous XML parser, as XML parses data while it downloads. But 
JSON doesn't (atleast I haven't found a way to get that working). In either 
way the JSON data is much smaller and much faster to parse.

I've recently added a feature that requires me to load several sources of 
json in parallel, parse in the background, and pass all the data back again 
using a Handler. This is a bit slower than I was hoping.

Would it be faster (and possible) for me to do this:
BackgroundThread extends Thread {
onCreate (Parent) {
this.parent = parent;
}
onData {
parent.addParsedData(x);
}
}

Parent extends ListActivity {
ListAdapter list;
onCreate {
   setListAdapter(list);
   new BackgroundThread(this);

public synchronized addParsedData(data) {

I'm thinking this won't be thread safe, as ListAdapter is in the parent 
thread. Am I right?
Should I instead inside the listadapter (which puts data in an array) have 
synchronized access to it's items?

[android-developers] http connection issue

2011-01-26 Thread arindam

Dear all,

I am trying to open a url like https://192.168.10.199/HSMobile/
HSService.asmx using httpclient and try to read response.

Now if i will open the above url in normal browser, it redirects to
one firewall page and asking login and password.After giving username
and password I able to view response. If i will type only firewall
page url and give login and password, it sows 1.1 Internal server
error 29.

Now I am doing it in android and using http post method. I am seding
login and password for firwall page. I am getting the same error. If
I use the actual URL i.e https://192.168.10.199/HSMobile/
HSService.asmx and sending the same login and password usng POST . I
am getting some other error.

[android-developers] ENHANCEMENT: Allow java public static finals to be referenced from XML

2011-01-26 Thread mkh

One example from an AndroidManifest.xml:

provider android:name=NotePadProvider
android:authorities=com.exampl.notepad.provider.NotePad /


This deliberately includes a typo that cannot be flagged by an IDE
because it is just a string.

Instead as an enhancement, why not define @java/ to be a reference
to the a public static final, then the above becomes:

provider android:name=NotePadProvider
android:authorities=@java/
com.example.android.notepad.AUTHORITY /

Now an IDE can provide completion on these @java variables, and the
IDE can also immediately flag undefined references. Also, the
definition of the authority string can be changed in one place, and
the code does not break.

Is there any reason this would not work -- it seems like the benefits
offered are significant.

[android-developers] How to define a CUSTOM font (Typeface) in application wide XML Theme/Style?

2011-01-26 Thread Eric

Hello,

I have been searching the APIs for a way, ANY way, to define a custom
(developer installed) font on a style, but it does not appear this is
possible.  It appears you have to resort to using:

Typeface.createFromAsset()

to load a font file stored in your assets directory, and then
programmatically set that font on every single text view you want it
used on, with 'setTypeface'.  This is not an acceptable solution for
our application, which is very complex, and we just want to define a
single theme using our custom font that can easily be applied on an
application, or at the very least, an activity wide level.

I discovered another possible way to set the typeface through the use
of SpannableString.  It seems you can use SpannableStringBuilder to
build a String that has styles defined over its contents.  However, of
the two types of Spans that allow you to style the text, StyleSpan and
TypefaceSpace, neither of them allow you to specify a CUSTOM font.
StyleSpan lets you pick a style, but the choices are limited to
'bold, italic, etc (which is font-independent).  TypefaceSpan does
allow you to specify a typeface 'family' name, however, as far as I
know, a USER installed custom font is unknown to the
Typeface.create(String family) method, and therefore, the system will
not be able to find my custom font.  *IF* TypefaceSpan had a
constructor that took a Typeface, I might be able to use that, but it
doesn't.

It looks like I might have to resort to writing my own Typeface span,
or somehow write custom code that plugs into the Android Style/Theme
system to allow me to apply a custom typeface to my application.

Any advice would be appreciated!

H-

Per your comments on usability (drill-down order in same report, etc) I'll
definitely pass those along to the team-  I'd recommend you also add a
feature request!  Votes on community-made feature requests have real
influence in how they prioritize their time :)

Regarding the ability to select custom variables in the left-nav with other
metadata, you can!  In left-nav, click on visitors.  It will be the very
last item in the expanded list.  From there you can drill-down from Custom
Variable names to specific values by clicking on them (much the way you can
drill-down with events by clicking on category/action/label)

Brill, alas!  But best of luck with Flurry :)

 Hi Alex, thanks for the comments. I don't want to deviate from the core of
 this post, but just wanted to touch on your point a smidge

 I could do what you suggested, and I can create a custom report to get the
 page views for custom var 1 and I can further drill to get the custom var 1
 values. And then I can further drill and get the details for custom var 2
 for a specific custom var 1 value.

 But what if I wanted the total page views grouped by custom var 2 first
 instead? I would have to create another report with that first instead.

 And what if I wanted to drill from custom var 3 to custom var 2 to custom
 var 1. Another report.

 Don't get me wrong, I can see that the reports are indeed powerful, but for
 ad-hoc what if reporting, they are just too much faff to have to create
 just to see a custom value for a chunk of users. And similarly, although the
 api is again powerful, it's a bit heavy handed for a simple why is that
 happening query when you see a lonely spike on a diagram and are curious as
 to why.

 If the custom variables are indeed metadata for page views and events, then
 why aren't they available to be selected in the list with all the other
 metadata i.e. language, continent, hostname, campaign, connection speed..?
 Surely all these other attributes are also metadata about a specific
 request..?

[android-developers] Need Help With AsyncTask HttpClient Internet Permission

2011-01-26 Thread guymac

My app attempts to do a https post from an AsyncTask's doInBackground
method. The app has permission
android:name=android.permission.INTERNET/permission in the
manifest in the correct location (it's the last line before /
manifest so it's at the same level as the application sibling
element).

But, while running in the emulator, it fails to get permission to
lookup the IP of the host, and if I switch to using a dotted quad
instead of a hostname, it gets a Permission denied socket exception.

Please help, I'm at my wit's end, it looks like everything is correct
from what I have read. Is it because the async thread doesn't have the
same permissions as the application? If so, what is the correct way to
spawn a potentially long-running http request from an activity?

Thanks.

[android-developers] Re: Tablet support up to 2.2


I think the tablets in general will be more likely to flip orientation
and good apps should handle that gracefully.  But I think they should
also have a lock orientation control at the OS or hardware level,
as it's common but annoying to have the view flipping as you lay down
in bed reading on an e-book reader (as an example).

One thing that I did in my app was to identify some views as heros
and some views as mere interface details.  I made a generic sizing
capability which makes a view, say, N% of the size of the whole
window, and I use that on all the hero elements.  So the buttons stay
the same size (finger sized) but the main elements of the screen use
their available real-estate more fully.

 (Not to toot my own horn, but see my Qwiz - Hiragana screenshots.)
 http://www.appbrain.com/app/qwiz-hiragana/cc.halley.droid.qwiz

Other applications just try to allow the additional area to be used
as a more convenient tableau, fitting more items in view at once,
because the individual items remain finger-sized.

 Do I take it that these tablets are designed to set landscape mode as

On 23 Jan., 19:00, Dmitri Plotnikov dplotni...@google.com wrote:
 Using ContentObserver for sync adapters does not sound like a good idea.
  There are several reasons for that:

 1. Data change notifications are not delivered to processes that are not
 running. So if your sync adapter is not running for one reason or another
 (and the system kills processes when it needs resources), then you won't get
 a notification.
 2. ContactsProvider sends only general whole adapter notifications,
 meaning that when any data element in the database changes it sends a
 notification to all observers regardless of what URIs they registered for.
  For example, somebody's presence in Talk changes - you will get a
 notification.  Most of these notifications will have nothing to do with the
 changes you need to sync, but there is no way for the adapter to tell.
 3. Having the sync adapter running at all times is a major waste of
 resources.

 Fortunately, the sync framework is designed to overcome all these issues.
  SyncManager manages sync adapters, calls them at the best time from the
 system's perspective, throttles their activities etc.  Sync adapters
 themselves rely on RawContact.DIRTY flag and the
 ContactsContract.CALLER_IS_SYNCADAPTER parameter to find and process
 incremental changes.

 There are examples of how that's done.  The most comprehensive example is
 probably the Exchange (IAS) sync adapter that you can find here:

   But that means that when the user first starts using this app, this

   Instead, they probably expect to synchronize the contacts already on

[android-developers] Re: One frame buffer per activity or one frame buffer per the whole system


I'm not sure that this is the right forum for platform-developers;
it's more geared to app-developers.

However, I will point out that there's an important entity between
the framebuffer level and the activity level, and that is the Window.
Activities come and go, Dialogs come and go, and their views are
attached to the window to be seen.  Activities themselves aren't
users of pixels, but Views are.  I don't think any storage is given
to a View; the View is merely consulted to render into the Window.

On a phone, the Window is basically 95% of the whole screen so you
don't necessarily think of this, but it's still a separate entity.
I could definitely see some more traditional WIMP implementation
offering a Desktop that contains multiple overlapping or tiled
Window areas, and in those Windows various Views/Activities being
managed in parallel.  Not saying that's the best vision of a huge
display on Android, but it may help understand the framebuffer
question you posed.

OK, thanks. Well in that case, I'll make a feature request here that I hope

 Known Issues

- Possible *inaccurate timestamps*: timestamps are recorded at the time
the application dispatches to Google Analytics, so if a user experiences
long periods of offline use, the timestamps may not be 100% accurate.


Can this be updated? It seems strange the tracker doesn't already track the
time the call was made and send this as the timestamp for tracking the
analytics in the dashboard. I can't imagine this would be very difficult to
change if the tracker is already caching the event data before doing a
dispatch later.

Thanks. Googler help always welcome around here. =)

[android-developers] Re: Edittext max characters - not set max


I think Andre was looking for a design limit, not how to set one.

The control can handle many pages of text, even with spanning styled
markup.  The EULA which I saw on one Android tablet was shown in a
simple text view, and it was about fifty pages of text on the tablet.
(The EditText control should have the same limits as the TextView,
as the EditText is just some additional features on the basic view.)

The answer is how much memory can you allocate?  Of course
the system needs to allocate resources to measure and typeset and
render all of that text.  If it's too long, consider showing the text
in pages or chunks.

Not only is this possible, it's what you should be doing.

[android-developers] Re: performance when passing background data to ui thread


If you're sure that all users of the data are within the same process
(the
same app), then using Java synchronized is the best way to go.
However,
you will need to be very careful to understand your semaphore
dependencies,
or deadlock will occur.  Not responding is almost as bad as Data
corrupted due to bad inter-thread communication.

The use of Bundles and/or ContentProviders are to enable inter-process
data
passing, and to avoid some of the danger of errant deadlock
situations.

 Hi

 I've got an app that spawns of a seperate thread. Parses JSON data into a
 structure. And passes it back to the main thread through a handler. Each
 part of data is sent through the handler individually. That worked fairly
 well with my previous XML parser, as XML parses data while it downloads. But
 JSON doesn't (atleast I haven't found a way to get that working). In either
 way the JSON data is much smaller and much faster to parse.

 I've recently added a feature that requires me to load several sources of
 json in parallel, parse in the background, and pass all the data back again
 using a Handler. This is a bit slower than I was hoping.

 Would it be faster (and possible) for me to do this:
 BackgroundThread extends Thread {
     onCreate (Parent) {
         this.parent = parent;
     }
     onData {
         parent.addParsedData(x);
     }

 }

 Parent extends ListActivity {
     ListAdapter list;
     onCreate {
        setListAdapter(list);
        new BackgroundThread(this);
     }
     public synchronized addParsedData(data) {
         list.add(data)
     }

 }

 I'm thinking this won't be thread safe, as ListAdapter is in the parent
 thread. Am I right?
 Should I instead inside the listadapter (which puts data in an array) have
 synchronized access to it's items?

[android-developers] How to access the Product Key on Archos tablets?

2011-01-26 Thread Armond

Hi Folks,

I need to access the product key (or whatever unique device ID) of the
Archos devices. I've found the following API mentioned on Archos
website which should work on Archos5 series:
Settings.System.getString(getContentResolver(), archos.product_key);

But it does not work on 101 tablets (returning NULL). Any clue?

Further Note: It seems that Telephony.getDeviceId() always returns
NULL on all Archos devices.

Thank you,
Armond

[android-developers] Sending AVRCP play command, getting spammed with broadcast

2011-01-26 Thread James

Hello.

I have some hardware that sends the AVRCP play command to the phone
upon bluetooth connection. What I am seeing is the MEDIA_BUTTON action
intent spammed over and over in the debugger. This is causing problems
with a few apps but mainly Pandora. Pandora will constantly play/pause
over and over. It is almost like the AVRCP command gets sent to the
phone which generates a MEDIA_BUTTON broadcast that keeps getting sent
out over and over.

I set up a Broadcast Receiver to catch it and try to determine what's
going on. Here is what is being spammed:


01-17 12:20:04.324: ERROR/NPT:(1558): Intent
{ act=android.intent.action.MEDIA_BUTTON (has extras) }
01-17 12:20:04.324: ERROR/NPT:(1558): KeyEvent{action=0 code=85
repeat=0 meta=0 scancode=200 mFlags=8}

which is the bluetooth Play/Pause media key. This is what it should
be, as the AVRCP command triggers this, but as I said, it's like the
OS just keeps spamming this.

I have tried using the abortBroadcast() method to stop it but that has
no effect. I am guessing the broadcast is non-ordered and can't be
stopped explicitly?

I have verified it is not the hardware spamming the AVRCP command by
debugging my firmware code. The spamming behavior also continues if I
unplug the hardware.

I am using 2.2.

Thanks.

[android-developers] Re: ENHANCEMENT: Allow java public static finals to be referenced from XML


It would create a dependancy loop:

 *   the app code requires R.java to be generated
 *   the R.java generation requires the XML to be scanned
 *   the XML @java would require the app code to be scanned

Maybe you intend the XML to be scanned twice, with two different
sets of rules as to what is allowed to be broken on each pass,
such that nothing broken slips through the two passes.  On the
first pass, find @+id kinds of things to add to R.java; on the
second pass, find @java kinds of things to validate the code.
All of the rest of the XML DTD rules would need to be covered
on at least one of those passes.  That kind of duplicity is
very error-prone and troublesome.

 One example from an AndroidManifest.xml:

 This deliberately includes a typo that cannot be flagged by an IDE

 Instead as an enhancement, why not define @java/ to be a reference
 to the a public static final, then the above becomes:

 provider android:name=NotePadProvider
             android:authorities=@java/
 com.example.android.notepad.AUTHORITY /

 Now an IDE can provide completion on these @java variables, and the
 IDE can also immediately flag undefined references. Also, the
 definition of the authority string can be changed in one place, and
 the code does not break.

 Is there any reason this would not work -- it seems like the benefits
 offered are significant.

 The control can handle many pages of text, even with spanning styled

 (The EditText control should have the same limits as the TextView,
 as the EditText is just some additional features on the basic view.)

 The answer is how much memory can you allocate?  Of course
 the system needs to allocate resources to measure and typeset and
 render all of that text.  If it's too long, consider showing the text

  Using ContentObserver for sync adapters does not sound like a good idea.
   There are several reasons for that:
 
  1. Data change notifications are not delivered to processes that are not
  running. So if your sync adapter is not running for one reason or another
  (and the system kills processes when it needs resources), then you won't
 get
  a notification.
  2. ContactsProvider sends only general whole adapter notifications,
  meaning that when any data element in the database changes it sends a
  notification to all observers regardless of what URIs they registered
 for.
   For example, somebody's presence in Talk changes - you will get a
  notification.  Most of these notifications will have nothing to do with
 the
  changes you need to sync, but there is no way for the adapter to tell.
  3. Having the sync adapter running at all times is a major waste of
  resources.
 
  Fortunately, the sync framework is designed to overcome all these issues.
   SyncManager manages sync adapters, calls them at the best time from the
  system's perspective, throttles their activities etc.  Sync adapters
  themselves rely on RawContact.DIRTY flag and the
  ContactsContract.CALLER_IS_SYNCADAPTER parameter to find and process
  incremental changes.
 
  There are examples of how that's done.  The most comprehensive example is
  probably the Exchange (IAS) sync adapter that you can find here:

It seems to me that the OP wants to synchronize contacts using the

But that means that when the user first starts using this app, this
account will be empty, and will synchronize... nothing.
Instead, they probably expect to synchronize the contacts already on
their phones (in the local account, or, more probably, in the gmail

That doesn't make sense. Requirements are for extra hardware, not the lack

[android-developers] ANNOUNCE: RoboGuice 1.1 now available

2011-01-26 Thread Michael Burton

Hello Android developers,

I'd like to announce the final release of RoboGuice 1.1!

http://roboguice.org

RoboGuice is a framework that brings the simplicity and ease of Dependency 
Injection to Android, using Google's own Guice library.  If you've ever used 
Spring (the #1 enterprise framework on Java, more popular than JEE itself) or 
Guice, you already know how convenient this style of programming can be.

To give you an idea, take a look at this simple example of a typical Android 
activity:

class AndroidWay extends Activity {
TextView name;
ImageView thumbnail;
LocationManager loc;
Drawable icon;
String myName;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

name  = (TextView) findViewById(R.id.name);
thumbnail = (ImageView) findViewById(R.id.thumbnail);
loc   = (LocationManager) 
getSystemService(Activity.LOCATION_SERVICE);
icon  = getResources().getDrawable(R.drawable.icon);
myName= getString(R.string.app_name);
name.setText( Hello,  + myName );
}
}


This example is 18 lines of code.  If you're trying to read through onCreate(), 
you have to skip over 5 lines of boilerplate initialization to find the only 
one that really matters: name.setText().  And complex activities can end up 
with a lot more of this sort of initialization code.

Compare this to the same app, written using RoboGuice:

class RoboWay extends RoboActivity {
@InjectView(R.id.name) TextView name;
@InjectView(R.id.thumbnail)ImageView thumbnail;
@InjectResource(R.drawable.icon)   Drawable icon;
@InjectResource(R.string.app_name) String myName;
@InjectLocationManager loc;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

name.setText( Hello,  + myName );
}
}

In this example, onCreate() is much easier to take in at a glance.  All the 
platform boilerplate is stripped away and you're left with just your own app's 
business logic.  Do you need a SystemService?  Inject one.  Do you need a View 
or Resource?  Inject those, too, and RoboGuice will take care of the details.  

RoboGuice's goal is to make your code be about your app, rather than be about 
all the initialization and lifecycle code you typically have to maintain in 
Android.

RoboGuice has been in development since August 2009.  1.0 was release in March 
of 2010, and since then has become the #1 dependency injection framework on 
Android, used in several big name Android applications.  1.1 has been baking 
for about 10 months and is pretty stable at this point.  


What's new in RoboGuice 1.1?  
+ Maven support
+ Testing support
+ Improved performance
+ Improved logging
+ A very cool Event system
+ And more: http://code.google.com/p/roboguice/wiki/ReleaseHistory


We know that RoboGuice won't be for everybody.  Although RoboGuice never 
prevents you from doing things the Android way, some people will still prefer 
seeing everything spelled out explicitly in their code.  And other people who 
write extremely high performance applications such as games may not want to 
incur the small overhead imposed by yet another framework.  But for people who 
want to build simple and straightforward code that's easily testable and easy 
to read, I encourage you to give RoboGuice a try.

We hope you like it.  Stop by our discussion forums if you'd like to have any 
help getting started.

Cheers,
Mike


PS. 1.1 owes a lot to its many contributors.  I'd like to shout out to: Manfred 
Moser, Adam Tybor, John Ericksen, Pierre-Yves Ricau, Tolik N_A, Christine 
Karman, Stephen Ng, Paul Butcher, Donn Felker, the robolectric guys at 
PivotalLabs, the sonatype guys, and Sam Berlin at google guice.  Thank you for 
all your help and contributions!

- XOR filter that just XORs the raw pixel values (and doesn't do
anything special depending on alpha values)

- Something that acts as a typical add blend mode.

I can't find any way to get these from combining the current modes
however.

 Unfortunately this is not possible so far that I have found. You'll
 have to do it manually or get tricky with using multiple XFermodes in
 conjunction with each other.

Re: [android-developers] Re: performance when passing background data to ui thread

2011-01-26 Thread Anders Aagaard

Thank you! I wasn't sure what was the cleanest way of doing it. And I'm very
familiar with threading, just not how java does it (and the synchronized
isn't something I'm familiar with from other platforms).

I'll try to push some of the sorting/filtering into the threads as well, to
reduce amount of time I spend in the main thread.

If you're sure that all users of the data are within the same process

However,
you will need to be very careful to understand your semaphore
dependencies,
or deadlock will occur. Not responding is almost as bad as Data
corrupted due to bad inter-thread communication.

The use of Bundles and/or ContentProviders are to enable inter-process
data
passing, and to avoid some of the danger of errant deadlock
situations.

Hi

I've got an app that spawns of a seperate thread. Parses JSON data into a
structure. And passes it back to the main thread through a handler. Each
part of data is sent through the handler individually. That worked fairly
well with my previous XML parser, as XML parses data while it downloads.
But
JSON doesn't (atleast I haven't found a way to get that working). In
either
way the JSON data is much smaller and much faster to parse.

I've recently added a feature that requires me to load several sources of
json in parallel, parse in the background, and pass all the data back
again
using a Handler. This is a bit slower than I was hoping.

Would it be faster (and possible) for me to do this:
BackgroundThread extends Thread {
onCreate (Parent) {
this.parent = parent;
}
onData {
parent.addParsedData(x);
}

}

Parent extends ListActivity {
ListAdapter list;
onCreate {
setListAdapter(list);
new BackgroundThread(this);
}
public synchronized addParsedData(data) {
list.add(data)
}

}

I'm thinking this won't be thread safe, as ListAdapter is in the parent
thread. Am I right?
Should I instead inside the listadapter (which puts data in an array)
have
synchronized access to it's items?

Re: [android-developers] Re: Application does not use all screen in Android tablet (with android 2.2)

This is easily fixed in the manifest. Either set minSdk to 4 or above, or
add supports-screens (look it up in the reference).

In general you need rooted phone to let you grab framebuffer. Then use
one of available apps i.e. ShotMe from Market

For most devices you can attach DDMS to it and take a screenshot with it.
