Re: [android-developers] First item in Gridview has null mAttachInfo

2011-05-24 Thread String

Or, it may well be a bug in GridView.

I've confirmed to my own satisfaction a somewhat similar bug in a GridView 
that I use: the view attached to the first item returns (0,0) for 
getHitRect(). Only the first item, but I'm not doing *anything* different in 
its creation or handling. Makes for a PITA when trying to handle touch 
events.

So, quite possibly it's a bug in GridView, not your code, and you'll need to 
work around it yourself.

The i.e. teh Settings App uses an AIDL Interface ( IMountService )

But I think only as part of the system build and signed with the

[android-developers] Re: View.GONE but still accepts UI events

2011-05-24 Thread Anm

Okay, so what is the rationale behind the animation null check? Why
would a view that is either GONE or INVISIBLE receive events just
because its animating (or more correctly, has a reference to a
Animation object, regardless of whether it is actively animating)?
Nothing I see in the Animation interface influences the view's
visibility state directly.

In the current code, we left animation objects attached to views to we
could reuse them. Instead of setting the reference to null, we had
set the Animation startTime to Long.MAX_VALUE, and later called
start(). This also avoided a invalidate/reset cycle for views that
were always the same size.

On May 23, 3:24 pm, Dianne Hackborn hack...@android.com wrote:
If you are receiving down events, then the view is almost certainly not set
to GONE or it is still animating. The code for this part of dispatching in
ViewGroup is pretty simply, and just immediately skips any non-visible
views:

for (int i = childrenCount - 1; i = 0; i--) {

final View child = children[i];

if ((child.mViewFlags VISIBILITY_MASK) != VISIBLE

child.getAnimation() == null) {

// Skip invisible child unless it is animating.

continue;

}

So be sure the view is actually gone, and that you haven't left an animation
in it.

On Mon, May 23, 2011 at 1:31 PM, Anm andrew.n.marsh...@gmail.com wrote:

This morning, I'm trying to animate the various state of a simple
game. I have a transparent cover ViewGroup with a start and other
buttons. When the user hits start, the entire cover animates away.
At the end of the animation, I set the cover View to GONE which looks
correct, but the start button is still grabbing touch events instead
of the game's view. I had to manually iterate over all the start
button and other views within the cover to setClickable( false ) and
setEnabled( false ) (not sure if both were really needed) before I
started receiving my touch events again on the layers below the GONE
ViewGroup.

This is something that I've run into a couple of times, and I'm just

When a view has visibility GONE, it is still allowed to accept UI

touch, where any positional state it likely an artifact of past/
invalidated state.

My colleagues and I cannot come up with any scenario where this
behavior would be desirable. Quite the opposite, it would seem to be
an easy way to limit the view tree traversal for event handling.

Any insight would be greatly appreciated.

[android-developers] Some questions about the driver and library..

2011-05-24 Thread Lulu L

Hi all,

I'm new in android. We got a big project and a tight schedule. So I need 
some help.

Description

We have a sensor and we want to use it in android. Currently we have the 
source code of the* driver* and the *framework *in LINUX, and the DLL files 
of the *middle ware*. We also need an* interactive program* at last.

The framework got data from sensor then pass them to the middle ware. After 
the middle ware processed the date, the framework sent them to application.

At first we thought we have to rewrite all those parts in JAVA and package 
them in an application. But it seems impossible..

Then I read the document of android. In the android architecture I found it 
relies on LINUX.

Questions

Since we have got the source code of *driver* in LINUX. So we don't have to 
do much work about the driver?

The *framework* seems like the abstraction layer. We should rewrite it in 
JAVA?

The *middle ware* is actually a library. Can we put it in the libraries 
layer in android?

The* interactive program *is an application. It will use the middle ware as 
a library?

Seems like we have to modify the source code of android system. So the 
application can only be used in the android system which we have modified?
Or there's some methods similar to the things we do in PC, we can install 
the driver and the library, then we can run the application?

PS: Are there some good books about android system? I didn't find many 
things about the architecture in the document.

I know little about android. I may have asked some stupid questions and my 
English is limited. Please forgive me if I made any mistake..

[android-developers] Camera App

2011-05-24 Thread New Developer

On my Zoom's home Screen it has the camera app, which has a button 
for front and back camera  and then a slider/button for  video or photo
When it saves a photo is it  IMG_mmDDhhMMss.jpg
All of which is great / perfect

Using the following code

ContentValues values = new ContentValues(); 
  values.put(MediaStore.Images.Media.TITLE, fName); 
  
values.put(MediaStore.Images.Media.DESCRIPTION, Image Capture by  ME);
imageUri = 
getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 
values);   intent   = new 
Intent(MediaStore.ACTION_IMAGE_CAPTURE);
 intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
 
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);

1) I get no front / back button
2) I get no slider  video / photo
3) It uses what I pass a fName.

How do I just plainly call the Camera app that exists on the home screen with 
all it's standard features and functions.  I want the front/back  video/photo 
and the file naming is perfect. So how do I just all it from my app?

thanks in advance

[android-developers] Re: View.GONE but still accepts UI events

2011-05-24 Thread String

My experience is that animation (at least pre-Honeycomb) overrides the 
equivalent properties of the view being animated. For instance, if you're 
animating a view's position, what will be shown on screen is the position 
from the animation, not what you may have set on that View's layout. 
Similarly, I think an AlphaAnimation will override any setVisibility() 
you've called on the View.

If this is the case, it's entirely possible that an invisible View will 
still be visible on screen if it's being animated, and the user will expect 
to be able to interact with it.

Now that you know the cause, it seems to me you could keep your Animation 
objects around somewhere else (and still reuse them), rather than leaving 
them attached to the Views. Just reattach them when you want to use them 
again.

Re: [android-developers] how to listen at ports for some network events?

ServerSocket is standard Java. Had you even bothered to search Google for:

java serversocket tutorial

you would have found nearly 100,000 hits, including:

http://download.oracle.com/javase/tutorial/networking/sockets/clientServer.html
http://zerioh.tripod.com/ressources/sockets.html
http://www.javaworld.com/javaworld/jw-12-1996/jw-12-sockets.html
http://oreilly.com/catalog/javanp2/chapter/ch11.html
http://www.kodejava.org/examples/216.html

And so on.

From an Android standpoint, you will need your ServerSocket to be
managed by a Service with its own background thread, most likely.

Also, bear in mind that what you are trying to do will not work unless
you and the server are on the same local network. Android devices are
not designed to be servers in this fashion.

A more general-purpose solution would be to use push services, like
C2DM, Xtify, and Urban Airship.

[android-developers] Toggling BT A2DP audio routing

2011-05-24 Thread Pent

There used to be some functions in AudioManager to route audio to BT.
Remaining these days is only setBluetoothScoOn().
For some reason there is no setBluetoothA2DPOn().

I get a lot of requests to enable / disable routing of audio
(notifications, media etc) to A2DP devices.

It seems that currently if such a device is connected audio goes
there, otherwise not (lets exclude the in-call case).

Is it possible to cause Android to connect/disconnect to BT devices as
a way of controlling the audio routing ? Or another
means of controlling the audio routing as setBluetoothScoOn() does ?

Thanks,

Pent

[android-developers] Force Killing Application

Hi,

I am getting below message from logcat. On Force closing of

If we do not have this implementation on application what will happen

[android-developers] Performance issues drawing on a canvas

I'm writing a pacman style game that has a lot of things to be drawn,
namely, the dots that pacman likes to eat.

I'm finding that the drawing of the dots is greatly hampering the
performance of the game. If I turn them off my app consumes much fewer
cpu cycles than if they are left on.

here is the code i'm using to draw the dots: http://paste2.org/p/1432169

 void drawDots(Canvas c) {
if (!this.drawDots)
return;

Paint p = new Paint(mPaint);
p.setColor(this.dotColor);
for (int i=0; idots.size(); i++)
{
Dot d = dots.get(i);
if (this.pacdroid.detectCollision(d))
d.disableDot();
if (d.enabled)
c.drawCircle(d.x, d.y,d.r, p);
//dots.get(i).draw(c, p);
}
}

Re: [android-developers] Re: Career as an Andoid developer. Is there any point?

2011-05-24 Thread Matt Powers

Programming apps in the traditional sense, on your own might not be a great 
career path. But android developers are in very high demand right now. You 
would be shocked to see big name companies and their inability to get on 
mobile, they know they have to but they don't know how. Additionally the 
android os is here to stay, now that it is going into the embedded world and 
the television market you will see more of a demand for that skillset

I was wondering what peoples thoughts maybe on the application that

point, as just about anyone will soon be able to create an app?
 
The link below shows what I am talking about.

Will programming for Android apps no longer be a specialist skill,

I'm going to argue that Android apps is not a career.
 
You won't find many people making real money on their apps.  Most 
people do
it for a mix of fun and profit, if that.
 
Android application development is a really niche area, without a solid
background in computer science or some related field, you'll quickly be 
out
of a job with no alternative.
 
But to answer your question, of course not, see the last point in Edsger

[android-developers] Re: Application crashes when downloding long data in from server and in loop.............

2011-05-24 Thread Streets Of Boston

This would mean your program put the entire 10Mbyte of data into one large 
JSONObject... 
Then you'd have, at least temporary, a 10MByte large json-string *and*a 10MByte 
(or larger) JSONObject hierarchy 
 
If this is the case, you'd probably run out of memory.

Re: [android-developers] Performance issues drawing on a canvas

2011-05-24 Thread Daniel Drozdzewski

Stuart,

There are few fixes straight away:

 - Have a predefined Paint object for your dots and use that instead
of creating new Paint object each time you enter drawDots()
 - assign dots.size() to a local variable and keep testing that
variable in the for loop, rather than calling size() method with each
operation
 - don't detect collisions in your drawing code
- worth testing whether Canvas.drawBitmap() (cached bitmap of a dot)
could be quicker than Canvas.drawCircle(); first one only copies
memory byte by byte, while second does some computation too
- and finally as String said: profile it


Then you have to think:
 - how complex is your collision detection? it has to be optimised and
you should not be iterating through all dots testing for potential
collision with PacMan; if you think about it, your dots don't move and
PacMan moves incrementally; there are few clever strategies that you
could use; in general collision detection optimisation strategies are
not trivial, but I am sure you could find something that would work
well for you and would not be too hard to implement;

have a look here as an entry to possible ideas:
http://en.wikipedia.org/wiki/Collision_detection

Better yet, use the official Google Calendar API, which has nothing to do
with Android specifically. Then your app is not dependant on various
firmware versions where the calendar stuff can and will change, thereby
breaking your code in each version.

Hey Robin,

I too wanted to thank you for the original source code you provided. An
extra big thanks for the updates you made for my copy at my request! The 3D
polygons look amazing, the 16-player online multiplayer component you added
works flawlessly, and I was able to upload the game, as is, right to the
Android Market. I am now making $1,000 per day thanks to the free source
code and art you provided completely free!

I gave the users your contact info so please take care of all customer
support and adding all new feature requests that come in. Pro bono, of
course. Thanks!

Since I just quit my day job thanks to you, I am flying out to Cancun for
the long weekend. Could you please book my flight and hotel and set up an
itinerary for my entire weekend stay? I will await you at 6AM - sharp! - on
Friday morning so yo can carry me from my place to the limo you
will chauffeur, then from the limo to the airport.

Please have croissant and coffee ready. You can feed me in between red light
stops.

Thanks!

It's so great to have a group that will provide you with anything you need
for free! - XOXO

[android-developers] Re: Performance issues drawing on a canvas

Thank you both for your suggestions, they are really helpful.   I was
able to optimise my code quite a bit.

My collision detection is pretty primitive, so I'll definitely try to
improve that.

public boolean detectCollision(Point target, int dist)
{
return (Math.abs(this.x - target.x)=dist  Math.abs(this.y -
target.y)=dist);
}



@Danie, you mentioned that I should split the drawing form the
animation code; What are the benefits of doing this? as both drawing
and moving are driven by the same loop?

 Stuart,

 There are few fixes straight away:

  - Have a predefined Paint object for your dots and use that instead

  - assign dots.size() to a local variable and keep testing that

 operation
  - don't detect collisions in your drawing code
 - worth testing whether Canvas.drawBitmap() (cached bitmap of a dot)
 could be quicker than Canvas.drawCircle(); first one only copies
 memory byte by byte, while second does some computation too

 Then you have to think:
  - how complex is your collision detection? it has to be optimised and
 you should not be iterating through all dots testing for potential
 collision with PacMan; if you think about it, your dots don't move and
 PacMan moves incrementally; there are few clever strategies that you

 not trivial, but I am sure you could find something that would work

[android-developers] Re: Career as an Andoid developer. Is there any point?

2011-05-24 Thread DanH

The basic problem is that you've got millions of high school students
and college dropouts who fancy themselves programmers, and they're all
writing Android apps, hoping to come up with the next big hit.  A very
small number will develop into decent programmers, and an even smaller
(microscopic) number will have that big hit.  But a very small portion
of millions is still a lot of competition.

Additionally, Android, as it's currently designed, does not have
legs.  The process model and UI are both too restrictive to be
extendable to the pads and other new paradigms of the future.

For the near term you're better off looking for apps that you can sell
to a business -- specialized apps their employees will use or apps
they will distribute free to customers.  Then you get your money up
front, in a reasonably predictable fashion.  (Here it helps to be able
to write Android, iPhone, and maybe Nokia and Blackberry apps, so you
can provide the customer with options.)

For the far term, you need to expand outside of the Android and even
the phone world, and learn other paradigms.  I'd recommend, eg, Qt for
desktop applications.  And you need to become familiar with HTML, CSS,
JavaScript, et al -- even though they are probably doomed to collapse
under their own weight in another 15 years, whatever follows will no
doubt draw from their basics.  Finally, you should learn about servers
and databases -- the general concepts will be around forever, even if
the specifics change.

And of course, the new big thing is the cloud, though I'd take that
with a grain of salt.

 The link below shows what I am talking about.

 Will programming for Android apps no longer be a specialist skill,
 hence not much of a career?

Re: [android-developers] Re: Performance issues drawing on a canvas

Yeah, drawing sprites on a canvas in general is slow.  Not to mention with
the added collision detection.
I would try doing a game-loop for for the animation/calculation and have a
single loop for drawing.
This makes sure you draw as fast as possible and your calculations run at a
steady rate.

Stuart,

It is true that there must be a main loop for animation (or a game).

However you ought to ensure that the drawing happens every X
milliseconds, so that the frame-rate is as independent from your state
computation as possible. Preferably it is a separate thread that
sleeps X milliseconds, then wakes-up and paints the current state.

State alone is updated constantly based on user input and game AI (in
your case pressing of the buttons moves PacMan, while ghosts are
chasing him automatically).

If you do state updates and painting in one loop, then you will notice
that game will feel differently, depending on how busy given level is
(plus many more factors impeding the computation performance).

What you will get, when you start optimising the collision detection
is that you will no longer iterate through all points, and then the
need to separate painting from state modification will be more
obvious.

I searched the nets for some tutorials, but found only this [*] which
explains it to a lesser extent. I am sure you will be able to find
something more comprehensive. Its for AWT, but the principles hold
regardless.

Re: [android-developers] Re: View.GONE but still accepts UI events

Because if it is animating, you don't want it to disappear and stop working
until the animation is done.  You are absolutely not supposed to just leave
an animation attached to a view.  Views that are currently animating are in
a special state, and have a lot of special behavior applied to them while
doing so.

On Tue, May 24, 2011 at 1:03 AM, Anm andrew.n.marsh...@gmail.com wrote:


 Okay, so what is the rationale behind the animation null check?  Why
 would a view that is either GONE or INVISIBLE receive events just
 because its animating (or more correctly, has a reference to a
 Animation object, regardless of whether it is actively animating)?
 Nothing I see in the Animation interface influences the view's
 visibility state directly.

 In the current code, we left animation objects attached to views to we
 could reuse them.  Instead of setting the reference to null, we had
 set the Animation startTime to Long.MAX_VALUE, and later called
 start().  This also avoided a invalidate/reset cycle for views that
 were always the same size.

Re: [android-developers] Re: Career as an Andoid developer. Is there any point?

I have seen that already, and while I don't disagree that for a very large
number of apps javascript/html5 just makes sense.
As it stands, it is just too limited.  Try doing any realtime android game
that'll actually work on low-end cell phones using javascript or html5 and
you'll have to get around a lot of limitations, bugs, incomplete
implementations, slow cpu, etc.

The way it stands, the closer you get to the hardware the better you can
control the performance.
In my opinion Android hits a sweet spot with Java because it makes it both
flexible enough and efficient enough for most moderately complex apps.

(For example, you can't do byte sockets in javascript.)

Re: [android-developers] Performance issues drawing on a canvas

Drawing a bitmap is going to be faster than drawing a circle.  Drawing a
circle requires making a curved path and filling it.  Drawing an
anti-aliased circle will be a *lot* slower than drawing a bitmap.

Basically you can assume, at least for software rendering, that the speed of
operations is:

(1) Rect fills are the fastest.
(2) Bitmaps (that aren't scaled or otherwise transformed) are a close
second.
(3) Everything else is a lot slower.

You'll notice that pretty much all of the Android UI itself is drawn with
rect fills and bit blits.  This is why. :)  (Text is a special case of
drawing bitmaps.)

That said, profiling is still always the the best indication of what is
slow.

 Stuart,

 There are few fixes straight away:

  - Have a predefined Paint object for your dots and use that instead
 of creating new Paint object each time you enter drawDots()
  - assign dots.size() to a local variable and keep testing that
 variable in the for loop, rather than calling size() method with each
 operation
  - don't detect collisions in your drawing code
 - worth testing whether Canvas.drawBitmap() (cached bitmap of a dot)
 could be quicker than Canvas.drawCircle(); first one only copies
 memory byte by byte, while second does some computation too
 - and finally as String said: profile it


 Then you have to think:
  - how complex is your collision detection? it has to be optimised and
 you should not be iterating through all dots testing for potential
 collision with PacMan; if you think about it, your dots don't move and
 PacMan moves incrementally; there are few clever strategies that you
 could use; in general collision detection optimisation strategies are
 not trivial, but I am sure you could find something that would work
 well for you and would not be too hard to implement;

 have a look here as an entry to possible ideas:

[android-developers] Upload a valid APK onto android market

2011-05-24 Thread Thomas

Hi Guys,
Below is a message I posted on Android market and on the Android
Market as question, and I wondered if anyone here has had a verified
basic4android apk that didn't want upload?
Best, Tom Birchmire

Download the app

http://thomasofneedham.com/android/FlyAwayHome.apk



The app works fine on my Android G1 - I'll have to get late model
Droid to test

I compiled my app using basic4android and got a Upload a valid
APK.message. Jarsigner output indicated a valid apk

X.509, CN=Tom Birchmire, O=thomasofneedham, C=us
[certificate is valid from 5/24/11 9:52 AM to 9/21/49 9:52 AM]


s = signature was verified
m = entry is listed in manifest
k = at least one certificate was found in keystore
i = at least one certificate was found in identity scope

jar verified.

[android-developers] Re: Performance issues drawing on a canvas

Daniel,

thanks for the link, it is VERY informative. Ok I'll separate the code
into two loops.

 Until I get that finished are there problems with detecting how long
the drawing/moving takes and then scaling the timeout appropriately?
This won't prevent the frame rate from dropping below 1000/timeout but
it should stabilize things:

FYI I'm not writing a game per-se rather a live wallpaper
---
void loop(){
//android.os.Debug.startMethodTracing(PacDroidTrace);
float dt = android.os.SystemClock.elapsedRealtime();


moveActors();
detectActorCollisions();
detectDotCollisions();
drawFrame();
checkForWin();

dt = android.os.SystemClock.elapsedRealtime()-dt;

mHandler.removeCallbacks(mDrawWallpaper);

if (mVisible) {
mHandler.postDelayed(mDrawWallpaper, timeout-(long)dt);
}
}

  Thank you both for your suggestions, they are really helpful.   I was

  @Danie, you mentioned that I should split the drawing form the
  animation code; What are the benefits of doing this? as both drawing
  and moving are driven by the same loop?

 Stuart,

 It is true that there must be a main loop for animation (or a game).

 However you ought to ensure that the drawing happens every X
 milliseconds, so that the frame-rate is as independent from your state
 computation as possible. Preferably it is a separate thread that
 sleeps X milliseconds, then wakes-up and paints the current state.

 State alone is updated constantly based on user input and game AI (in
 your case pressing of the buttons moves PacMan, while ghosts are
 chasing him automatically).

 If you do state updates and painting in one loop, then you will notice
 that game will feel differently, depending on how busy given level is
 (plus many more factors impeding the computation performance).

 What you will get, when you start optimising the collision detection
 is that you will no longer iterate through all points, and then the
 need to separate painting from state modification will be more
 obvious.

 I searched the nets for some tutorials, but found only this [*] which
 explains it to a lesser extent. I am sure you will be able to find
 something more comprehensive. Its for AWT, but the principles hold
 regardless.

[android-developers] SimpleCursorAdaptor ListView using an TextView and ImageView with over 400+ rows Memory Issues

2011-05-24 Thread gcstang

Is this the best way or are there others?

I extend SimpleCursorAdapter and override getView(int position, View
convertView, ViewGroup parent)

I retrieve my Cursor, inflate my ImageView and TextView, pull the data
from the Cursor and populate the TextView and ImageView
on the ImageView I store my images in the database as Blob's.

When I retrieve my Blob I pull it out as a byte[] and convert it to a
Bitmap as below:
Bitmap bmp = BitmapFactory.decodeByteArray(img, 0, img.length);

Then I set my Bitmap on my ImageView as :
iv.setImageBitmap(bmp);

Now I can scroll down fine no issues but when I start scrolling back
up the list I get major memory issues and sporadic jumping(from when
the garbage collection catches up).

Can anyone tell me what the best way to accomplish this task would
be?  Is there a way to recycle the bitmaps that aren't in view and
when approaching them pull them and display again?

I've searched for months and tried various techniques but I'm at a
loss to finding the one that will allow me to accomplish this task.

Thank you in advance.
