There are no rules on how many times getView() will be called. You
need to ensure that getView() is very fast.

I have determined this by logging the getView method of the adapter.  When 
operating normally, getView is only called for the new row to be displayed 
when scrolling.  In my case, getView is called for every row.

Re: [android-developers] Spinner example has no prompt

Since you mentioned 4.0.3 and api level 15...

With Holo themes, spinners are no longer popup

Adding a text label to the layout somewhere near the spinner should work.

yes, but that would take up more real estate.

i ended up adding a prompt string as the first
element in the list model when i made the array
adapter. and then removed it when the user made
a choice that was not the prompt.

is this a sane thing to do?

or is there a better way? maybe change adapters

[android-developers] Re: Image Quality problems using Canvas and canvas.scale(Scale, Scale);

2012-01-25 Thread JamesColeman

Thank you for your reply, I appreciate the input!

Overall I agree with what you are saying about the "bleeding
obvious".  However, I down scaled the exact same images on
BlackBerry's and had no problems whatsoever.  In our graphics arts, I
downscale graphics all the time and end up with great looking images.
The problem I am experiencing is something particular to Android
Canvas scale and is similar to the problem in the link I posted.

In intend to have a pinch zoom control the canvas scale so it looks
like I have a challenge ahead of me. One would think if I can pull it
off on a BlackBerry I could do it on an Android somehow.  I hope I am
not stuck with it as you say.

Re: [android-developers] Re: Partial invalidation in custom Android view with hardware acceleration

2012-01-25 Thread Andrew Hughes

So, with the new hardware accelerated pipeline, in the case where there
could be *thousands* of drawing calls (such as drawLine(s) or drawPath) is
it better to not draw to a bitmap cache but rather issue those calls
directly to the Canvas provided by onDraw()? What about when scrolling?
Should a bitmap cache be used then, or should all the draw calls be
continually re-issued while scrolling?

I understand (and have seen) how this is slow when not using hardware
acceleration, but I don't understand the new rendering pipeline and
internal use of DisplayList enough to know which is the proper
implementation (and I would love to understand it better!). My gut wants to
use a bitmap cache, but you made it sound like with the hardware
acceleration pipeline you shouldn't have to?

Thanks,
Andrew

[android-developers] Screebl 3.0 Beta Test

2012-01-25 Thread keyeslabs

Looking for some brave souls to test a ground-up rewrite of Screebl.  The 
engine is mostly there, but things aren't pretty yet.  If you're 
interested, I've published to the 
market: https://market.android.com/details?id=com.keyes.screebl.beta.

Still wish Google provided a more integrated beta program for developers so 
that this could be managed from the developer console.

Anyway, let me know how things work out.  Thanks in advance.

[android-developers] VideoView.setLayoutParams - ClassCastException

2012-01-25 Thread John-Marc Desmarais

Hi,

I have a VideoView in a LinearLayout with 2 other boxes. In trying to
create a full screen video, I am doing the following:

private boolean isFullScreen = false;
public void onClick(View v)
{
VideoView vv = (VideoView) v.findViewById(R.id.videoView1);
LinearLayout.LayoutParams lp =
(LinearLayout.LayoutParams)vv.getLayoutParams();
if (isFullScreen)
{
isFullScreen = false;
lp.weight = 0.2f;
vv.setLayoutParams(lp);
v.invalidate();
}
else
{
isFullScreen = true;
lp.weight = 0f;
vv.setLayoutParams(lp);
v.invalidate();
}
Log.v(LogName.onClick, "Video switch to " + (isFullScreen ? 
"Full
screen" : "Normal size"));
}

I am getting an exception:

Thanks for the answer, but I already looked at these sites. there I found
the problem but not the solution or other way to do what I need.
Regrading your question, yes very few application will need something like
but those few will be something else then your regular applications, and I
am no hacker. If I were to ask this question in linux or windows forums I
wouldent get that reply.
Why? because os needs to give power to developers and not strip it from
them. I did really nice  things in linux and windows which could be amazing
in smartphone.
Well anyway thanks for the answer, I will keep looking

Re: [android-developers] Using various parts of an image to select on. Possible?

There is a way to intercept touch events sent to a view:

http://developer.android.com/reference/android/view/View.html#setOnTouchListener(android.view.View.OnTouchListener)

... and it should work with an ImageView and such.

I'd also consider writing your own view subclass and handling the UI
interaction completely within that view:

http://developer.android.com/reference/android/view/View.html#onTouchEvent(android.view.MotionEvent)

You could also subclass ViewGroup - or probably one of the layout classes,
such as FrameLayout, and then use this:

http://developer.android.com/reference/android/view/ViewGroup.html#onInterceptTouchEvent(android.view.MotionEvent)

... to direct events to this view or to enclosed views, if you wanted to do
it that way.

[android-developers] Using various parts of an image to select on. Possible?

2012-01-25 Thread darrinps

OK, so this is a good one.

I need the ability to allow an image to be re-sizable (pinch zoom for
example) and scrollable (finger drag) yet still allow parts of that
image to be pressed and depending on which part is pressed, have a
different action take place.

For example, suppose my image had four areas where each area (denoted
by []) can be selected like this:

[][]
[][]

If the user pinch zooms the thing it might look like this:

[   ][   ]
[   ][   ]

I thought about breaking the image up into areas and using image view
buttons but I am not so sure about scrolling the thing or zooming.

So, is there any way to specify coordinates on an image and based on
where the user presses know what area they touched? Of course this
would need to be tracked and adjusted as they pan/zoom the thing.

Thanks!

[android-developers] Re: android accelerometer to measure distance

2012-01-25 Thread TomL

http://en.wikipedia.org/wiki/Kinematics#Displacement 

Acceleration is delta velocity over delta time.  Velocity is delta position 
over delta time.  If you can accurately sample the acceleration values over 
a period of time, you could calculate the changes in velocity and therefore 
the overall change in position.

In practice, I don't think that smartphone accelerometers are anywhere near 
as accurate as you'd need to be able to do this.  If they were, smartphones 
would cost as much as missile guidance systems.

[android-developers] Bluetooth without UUID?

2012-01-25 Thread darrinps

I am working on an Android Bluetooth application to mimic one done on
Blackberry.

The Blackberry app connects to a Bluetooth server without issue.
My Android app OCCASIONALLY connects to the Bluetooth server (pairs
and discovers just fine every time)

I began to suspect the common UUID they were using on the server side
wasn't always what I was using (the server perhaps rotates it
somehow?) but when I asked the Blackberry person what UUID they were
using, the answer I got back was "We don't specify ANY UUID at all and
just use Serial Port Profile".

Well, it is my understanding that SPP is just another name for RFCOMM
which Android uses.

So, can anyone tell me why sometimes, without doing anything
differently (not bouncing Bluetooth, not bouncing the application,
etc.) I can sometimes connect and sometimes not?

Also, is there some obscurely documented way to connect like
Blackberry without specifying the UUID?

Thanks!

[android-developers] Re: javax.management

2012-01-25 Thread Jan Burse


Dear All,

I found the following substitute for what I needed
from javax.management. There is:

 void   onLowMemory()
 This is called when the overall system is running
 low on memory, and would like actively running process
 to try to tighten their belt.
 http://developer.android.com/reference/android/app/Application.html

And:

 public longthreshold   
 The threshold of availMem at which we consider memory to
 be low and start killing background services and other
 non-extraneous processes.

http://developer.android.com/reference/android/app/ActivityManager.MemoryInfo.html

There seem also to be more APIs since Level 14, for example
onTrimMemory in Application, but I will try level 10 for the
moment.

I also found SystemClock useful, but I am still missing
an API that would give me some statistics about how much
time spent in GC.

Best Regards

Mark Murphy schrieb:

You are missing the point. If I am understanding the documentation for

Since I only need the memory threshold functionality
I could easily implement the functionality in Android
by myself by polling Runtime.freeMemory() in a thread.
The later is available in Android.

But it would be more handy if there is some existing
lib or even an API in Android that I did not yet see.

[android-developers] Re: "IllegalStateException Fragment not attached to Activity": a challenging issue?

Thank you Kostya.

Yes, my intent is to invoke those methods from a worker background
thread.

You assume that I want to get i18n string to update the UI, but this
is not my exact use case. I need to get an i18n string, because I want
to prepare the computation of a string (imagine that the string
computation takes a lot of time, it may make sense, for instance),
which will eventually be used on a UI thread to update the display,
which is slightly different.

Your phone settings changes while the background thread is still
running example is a very well chosen use case, and I do not see how
the AsyncTask enables that properly neither.

Not to mention the fact that there is no synchronization mechanism
around the "Fragment.getActivity()": if I test its nullity, nothing
prevents it from being null in the if statement body. I cannot figure
out why the "Fragment.getText()/getString()/getResources()" methods
correct execution may need to depend on the fragment state. At least,
the "Fragment.getActivity()" method should throw an
"IllegalStateException" instead of "null" when the fragment has been
detached, or even better, a dedicated exception also used for the
previous methods.

I'm still investigating, on how to handle that properly...

Édouard

Re: [android-developers] Spinner example has no prompt

Since you mentioned 4.0.3 and api level 15...

With Holo themes, spinners are no longer popup dialogs - they are dropdown

Adding a text label to the layout somewhere near the spinner should work.

[android-developers] Re: "IllegalStateException Fragment not attached to Activity": a challenging issue?

( responding back to the list )

Yes, that was my point.

Even if each individual framework method you're calling was be thread-safe
(which it may not be) , overall, your code sequence is not thread safe.

Mark already gave one suggestion.

Here is another:

Since you're talking about getting strings to update the UI, you won't be
needing them until doing that - calling textView.setText and such. That is
only safe to do from the UI thread.

With this in mind, postpone getting the strings to just before you need
them, on the UI thread, to avoid the issue of accessing Context altogether.

This most likely means that your background thread would need to return
some kind of "result" object that describes enough of the outcome of what
it was doing --

-- so that code on the UI thread can make intelligent decisions on what
exactly to present in the UI --

-- but that's probably a good thing anyway: abstract, clean separation of
work / UI code, etc.

Your idea with keeping a context reference for the duration of the worker
thread might also work, but I'm not sure it is safe for all cases - for
example, the user going into phone Settings and changing the language while
your worker thread is running.

Re: [android-developers] custom ui widgets?

2012-01-25 Thread John Davis

Hello TreKing,

Yes, the diagonal placement might not work with the gridview, but I can
adjust my goal to fit the gridview.

Very true about many viable ways.  I'm just trying to get a rough heading
from the established guide before I head out into the wilderness.

Possibly. Your image to me looks like it would require a custom layout
manager, but I haven't done that, so I can't say that will full certainty.
Like most programming tasks, there are likely several viable ways to

Hello TreKing,

Thank you.  I'll look into that.  FWIW, I've gotten some other suggestions
off list.  It appears that I will need
to learn gridview.  Possibly the solution to my problem is a custom
component consisting of a GridView with three textviews.

Does that seem right to you?

Do you expect to run this code on a background worker thread?

If so, how are you ensuring that the UI thread won't change the fragment's
state while this code is running?

[android-developers] Re: "IllegalStateException Fragment not attached to Activity": a challenging issue?

Thank you Mark.

If you implement "Fragment.getContext()" the following way, I think
that it works:

public final Fragment.getContext()
{
  if (isDetached() == true)
  {
if (getView() == null)
{
  throw new IllegalStateException("...");
}
   return getView().getContext()";
  }
  else
  {
return getActivity().getApplicationContext();
  }
}

Which leads to me to the question: why Android developers did not
expose such a method, which would prevent us from having to resort to
the "getActivity()"...

[android-developers] custom ui widgets?

2012-01-25 Thread John Davis

Hello

I have a good understanding of the basic ui api.  I can use TextViews and
layouts, but I don't know anything about custom UI usage.

I would like to build a UI which looks something like this:
http://s1258.photobucket.com/albums/ii540/netskink/?action=view¤t=ssicons.jpg

Possibly a component with three lines of text with two font sizes.  Any
suggestions on what I should do?

You are welcome to pass in the Application object to the background
thread, if you think it will work. I have not tried it with string
resources, so I have no idea how reliable it may be in that role.

getContext() would be pointless, as there would be no guarantee that
the returned Context would be valid for a background thread.

[android-developers] Re: "IllegalStateException Fragment not attached to Activity": a challenging issue?

Thank you Mark.

Yes sure, this is a way to address this issue. But if the i18n string
I need to get depends on the result of a web service call, this means
that I need to provide all i18n strings at AsyncTask build time. And
if I need to use the "getString(int resourceId, ...)" form? In that
case, I have to check the "Fragment.isDetached()" method, before
attempting to use that i18n form, right?

I think that this is not bad design to make the Android application
context accessible from a background thread, isn't it?

I'm really try to understand the motivations which account for why the
Android developers did not expose such a "Fragment.getContext()",
instead of exposing "Fragment.getString()/getResources()/..."
methods...

Never refer to a fragment or an activity from a background thread. For
example, if you use AsyncTask, pass your string into the task's
constructor or execute() method.

Yes, you pass the data into the thread.

[android-developers] "IllegalStateException Fragment not attached to Activity": a challenging issue?

Hello.

With the Fragment API, the easy and straightforward way to access to
the i18n is to use the "Fragment.getString(int resId)" method.
Unfortunately, the implementation resorts to the underlying attached
Activity, which is only available between the
"Fragment.onAttach(Activity activity)" and the "Fragment.onDetach()"
methods life-cycle. As soon as a background thread attempts to invoke
the "Fragment.getString(int resId)" while the fragment is not attached
to its view, the caller thread gets an "IllegalStateException" with a
message of the form "Fragment MyfragmentClass{X} not attached to
Activity".

This involves that any worker thread which have been starting
executing a command when the fragment has been started, and which is
still being executing while the fragment has been detached (a typical
case is leaving the hosting activity), will need to check the
"Fragment.isDetached()" method, before attempting to access to the
i18n. One may claim that the background worker thread execution should
be interrupted as soon as the "Fragment.onDetach()" callback is
invoked, so as to get rid of the problem. But this leads to more code:
either to have a boolean somewhere to indicate whether the thread
should be still be running, or a test every time the "
"Fragment.getString()/getResources()/..." methods are invoked.

My question is: why not having exposed a "Fragment.getContext()"
method? A work-around, would be to define one, which returns
"getActivity().getApplicationContext()" as long as the fragment is
attached, and something like "getView().getContext()" in other cases.
But if the Android developers did not expose a "Fragment.getContext()"
method, coupled with a "private Context context" attribute, they must
have their reason. Is it to make the fragment more quickly garbage
collected, by reducing the amount of time when there is a double link
between between the fragment and its hosting activty?

To my opinion, accessing the Android context from a fragment or from
an activity should be done the same way (and this is actually the case
through the same for the "Activity/Fragment.getString()/
getResources()"), so as to ease porting activities to fragmented
activities. Did someone solve this problem of detached thread
accessing the i18n in an elegant and efficient way? What are your
thoughts about that issue?

Thank you for your time. Regards,
Édouard

[android-developers] Best Application Data Backup solution?

2012-01-25 Thread gcstang

What is the best solution to integrate backup, external to the device
for an Android application?

Ideally the solution will be cheap, integrate easily with an existing
application and will be seamless to the clients.

I know Google Backup is limited so most likely it will not work, but
there has to be other solutions.

Backup per client will be roughly 5-10MB in size.

Thank you in advance.

Re: [android-developers] Re: Strange behavior with Theme.DeviceDefault.Light

2012-01-25 Thread Ricardo Amaral

It does seem to contradict but looking at *
res/values/themes_device_defaults.xml* on API Level 15 source (look here: 
http://pastebin.com/rj5LwgVf) we can see that both the *Theme.DeviceDefault*and 
*Theme.DeviceDefault.Light* inherit from *Theme.Holo* and *Theme.Holo.Ligh*t, 
respectively. But they both override some styles. For some reason these 
overrides (this is just my guess though) are messing up the Light theme and 
not the default one.

We can also see on...

Line 179:




Line 325:




There are no overrides and when I use this *Light.NoActionBar* theme, 
everything works as expected. To me it's not a problem because I use a 
library for the ActionBar, not the native one. But for people who does need 
the native one, this is not a good solution.

There's something really strange going on with ICS themes...

[android-developers] Re: How I use Web Services in android.?

2012-01-25 Thread Harpreet Singh

Hello Sir,

What I really want is that::
Activity 1:: Login Page (asks for email address & access code).
Activity 2:: Application Form (a complete form to fill) then SUBMIT.

So right now I am at Activity 1, I want that when user fill email
address and access code, it check that from online running site
(http://www.premiere-concierge.com/services.aspx) using soap and give
the response regarding Login Successful or not.

If Login is successful, then it move to Activity 2 otherwise shows an
error( i am using textview to shows the error on Activity1.)

I am studying about SOAP, as I am new to this concept, never used any
web service before.
so the doubts came::

1. Where to write all these codes of SOAP (i read that it has to be
written in xml file, then where to save this/these xml file(s) in
Project [ either in layout, in assets or in values {where?}]).
2. What names should I use to save this file? (Is soap_service.xml is
OK?)
3. Should the Soap Request & Soap Response be on same xml file or not.
4. Now How I implement this/these xml file(s) in Java Code.

Examples, Samples, links... Anything preferred.

Sorry for all these silly questions but doubts have to be cleared.

Thanks.
Harpreet.

The meaning is that you are reading a blog post from a non-developer,
rather than reading the original WebKit mailing list post:

https://lists.webkit.org/pipermail/webkit-dev/2011-August/017738.html

That is impossible to answer.

It also has nothing to do with this list, which is for building
Android applications with the SDK.

Re: [android-developers] Re: Strange behavior with Theme.DeviceDefault.Light

Normally I use @android:style/Theme.Holo.Light (and its dark counterpart),
and it works very well except for custom alert dialog content, but that's a
"known known" and there are ways to deal with that.

Just tried out @android:style/Theme.DeviceDefault.Light on my Galaxy Nexus
with 4.0.2 and the result is the same as you're seeing in the emulator - it
looks quite different from @android:style/Theme.Holo.Light, weird and
unreadable.

This seems to directly contradict the blog post you linked to above:

"Google's Nexus devices alias DeviceDefault to the unmodified Holo themes."

Is the Galaxy Nexus a Nexus device? Is it a Google device? Does anyone know?

-- Kostya

PS Another cute bug is that bringing up a context menu in an
ExpandableListView pushes the expandable view's content veritically off the
screen - so you have an unreadable context menu over an otherwise purely
white screen.

RE: [android-developers] Re: Encoder???


hi skink,
  Now i have used inputstream but it give me Exeption (null) at 
while((bytesRead = is.read(buffer)) != -1) on server side.

here server side code that i am using.
 try
 {
// create stream to Network
  InputStream in = clientSocket.getInputStream();

   // create stream to file
  OutputStream os = new FileOutputStream("video.3gp", true);

  byte[] buffer = new byte[4096];  
int bytesRead; 
while((bytesRead = is.read(buffer)) != -1)
  {

   os.write(buffer, 0, bytesRead);


 }
is.close();  
os.close(); 
  }
   catch (Exception e)
   {
System.out.println(e.getMessage());
   }

Regards.

Re: [android-developers] Re: Existing joomla site in Android..

2012-01-25 Thread Daniel Drozdzewski

It is becoming off-topic...

You will have to use User-Agent detection on the server site (easily
done in PHP or anything else)  to return the appropriate version of
the page or use JS to redirect based on some properties of the browser
rendering the page.

First solution depends on User-Agent, which could be spoofed and is
not 100% watertight.

Second one, that I found (jQuery):

if($(window).width() < 480){
 window.location = "mobile.yoursite.com"
}

...is a bit rigid and assumes a lot about the screens that your page
is being rendered on. If you are limiting the content only because of
the screen resolution, then you are safe, but if you want to remove
say flash or some other file types, resolution is not the way to
detect the agent. Some phones have more pixels than some desktop
platforms.

Also, if it is only images that you are concerned with, you could use
adaptive images:

http://adaptive-images.com/

HTH,

Daniel

hi skink,
 Thanks for your reply, I am using server side code to receive each 
frame is perfect. but when i use this server for mediaRecorder it gives the 
invalid stream header: , i am using 
ObjectInputStream to receive the data. on client side (android), i  am using 
the ParcelFileDescriptor.fromSocket(socket), is ParcelFileDescriptor send video 
in object form? 

 here is my server side code.

try
   {
 // create stream to Network
 ois = new ObjectInputStream(clientSocket.getInputStream());

   // create stream to file
FileOutputStream fos = new FileOutputStream("video.3gp", true);
ObjectOutputStream out = new ObjectOutputStream(fos);

  while(true)
  {

 // read data in object form from network
byte [] byt = (byte[]) ois.readObject();

  // write data to file 
 out.write(byt);
 out.flush();
 }
}
catch (Exception e)
{
  System.out.println(e.getMessage());
 }

Re: [android-developers] Re: How to continously updating data from XML

2012-01-25 Thread Kristopher Micinski

You can look at some AsyncTask examples, but really, you should also
put some interest into this:

http://developer.android.com/guide/topics/fundamentals/loaders.html

This was introduced in 3.0 (which I haven't gotten as much of a chance
to play around with as I should have yet).

I think that Mark Murphy points out something to do <3.0, but I don't
remember at the moment.

AsyncTask should have examples, as well as a tutorial or two out there.
