Actually, that won't work. This is because we do not know what orientation 
is in when the app started.

My current solution is to detect what orientation it is in, 
then setRequestedOrientation to the current orientation. This works nicely.

[android-developers] Android vs. Everyone: Live! July 12!

2012-07-09 Thread Bill Mote

At last month's It's really time to get serious about PhoneGap meeting, 
hosted by our sister group All Things Mobile, I threw down the gauntlet: 
build a tip calculator in your respective platform to induce dialog about 
its merits.

They have willing participants for iOS, Windows Mobile and PhoneGap. I will 
be carrying the mantle for Android.

This should create some interesting compare and contrast discussion. Come 
help represent the green! Viva-la-Android!

[android-developers] creating Bitmap from pixel data without copying the data

Hello,

I have a bunch of pixel data in an int[] that I want to turn into a
Bitmap instance.  The problem is, the pixel data is so big it barely
fits into memory.  I thought it would be no problem, surely I can pass
the int[] to a Bitmap factory method which simply wraps it in a Bitmap
instance.  Unfortunately, this does not seem to be the case -
createBitmap(int[] colors, int width, int height, Bitmap.Config
config) seems to allocate its own int[] and copy the passed in int[]
into it, which fails if there is no memory for another copy.

I simply need to turn the image stored in the int[] to a .png on
external storage so actually any of the following would be good enough
for me:

- as mentioned above, a way to create a Bitmap so that it doesn't try
to allocate another useless copy of the data

- an accessor on Bitmap to return the Bitmap's pixel store as an int[]
(that way I wouldn't have to allocate my own int[] and would be able
to write directly into the Bitmap-owned memory)

- a way of accessing (an equivalent of) Bitmap.compress()
functionality without having a Bitmap

Amazingly, none of the above seems to be available!  Bitmaps tend to
be large objects in memory, surely there must be ways to handle them
in a memory-efficient manner...

Cheers!

[android-developers] Testing Android inapp subscription: You already own this subscription

2012-07-09 Thread howa

 I am testing Android inapp subscription with a test account, after I 
entered a real credit card to buy, the subscription is ok, but I cannot 
find the token in the json response.

So in the developer console, I cancelled the order, when I try to 
re-subscribe again, it now show me the alert You already own this 
subscription.

When I click the Detail in the box, it opened the Play Store app, but 
showing Item not found

Anyone experienced this error before?

[android-developers] Re: creating Bitmap from pixel data without copying the data

Bitmap behaves like that because it allocates memory on the native heap for
storing its bitmap data, meaning: it cannot use your Java int array and
must make a copy instead. For getting around that problem you should
reconsider what you are doing. Try to break your big (memory) problem into
several smaller sub-problems. I don't know where your pixel int array
originally comes from, but at some point you must have it either loaded
from somewhere or constructed.

You could instead operate directly on an already allocated Bitmap object
and modify its pixel data instead of having you int array as a step in
between. So if you are loading your int array from a file for example, just
apply that data directly to the Bitmap. If that array is constructed by
your code, then change the algorithm to store its calculations directly in
the Bitmap object.

But maybe you do not need a Bitmap object at all. If you want to draw on a
Canvas object, then you could make use of the following method instead,
which takes a Java int array as argument:

canvas.drawBitmap (int[] colors, int offset, int stride, float x, float y,
int width, int height, boolean hasAlpha, Paint
paint)http://developer.android.com/reference/android/graphics/Canvas.html#drawBitmap%28int[],%20int,%20int,%20float,%20float,%20int,%20int,%20boolean,%20android.graphics.Paint%29

Re: [android-developers] Re: creating Bitmap from pixel data without copying the data

I had to work on a bitmap intensive app last year and ran into all these
problems. First of all, you are right. You can allocate almost whatever
native heap you want. On our test devices it was almost up to a GB for
example.

No matter what Google says, by my own and obviously your observation
bitmaps behave differently though. I was curious and just looked up the
source code for the native pixel data allocation. It looks like a method
called
GraphicsJNI::allocateJavaPixelRefhttp://source-android.frandroid.com/frameworks/base/core/jni/android/graphics/Graphics.cppis
to blame for that. Allocation is not really completely done in native
heap, but Java memory is being requested via the JNI method NewByteArray.
As far as I know that allocated array resides on the native heap until it
is released and copied back to Java. That probably only happens when you
alter the pixel data from Java. Which means that the get and setPixel
methods must be really slow because in worst case they can cause heavy copy
operations between JVM and native code for each access.

In any case, allocation of bitmaps does depend on the available Java heap
space, even though that space is not necessarily claimed when your Java
code does not access the raw pixel data.

The only other option that comes to my mind for speeding up things would be
writing some NDK code and using a PNG library for encoding the pixel data
in native code. Passing that int array to that native code is
straightforward. With a trick you can even access the original Java int
array directly without waiting for a copy. This is possible with the JNI
function
GetPrimitiveArrayCriticalhttp://docs.oracle.com/javase/1.4.2/docs/guide/jni/jni-12.html#GetPrimitiveArrayCritical.

There is no guarantee, though that direct access works in any case. The
documentation of that function explains the limits pretty well.

Bitmap allocations always count towards your heap limit. Until Android 3.0,
Bitmaps were allocated on the native heap but counted against your maximum
Dalvik heap. Starting with Android 3.0, Bitmaps are allocated directly on
the native heap.

[android-developers] How do users find new apps?

In the old Android Market store, uploading a new app would automatically

they have removed this tab and replaced it with Top apps only. I'm 
wondering how developers nowadays are suppose to get *organic *downloads 
from people simply browsing the app store. This new system doesn't seem to 
give a chance for new apps to make any impressions in front of a big 
audience. Is the only way now through advertising and self-promotion of the 
apps? Thank you!

Re: [android-developers] How to add date and time on captured image

Exif data is meta-data...  That means it is data that is stored with the
image, but is not displayable.  If you want to put the date and time on the
image, then you will need to modify the actual image...

Try using Google, it is your friend:

[android-developers] Re: creating Bitmap from pixel data without copying the data

2012-07-09 Thread RichardC

A quick search turns up quite a few Java PNG encoders with various license 
conditions.

Encoding a PNG will not require copying the PNG again so grab one with 
source, a license you like, and if necessary modify it to write directly to 
an output stream.

 Hello, 

 I have a bunch of pixel data in an int[] that I want to turn into a 
 Bitmap instance.  The problem is, the pixel data is so big it barely 
 fits into memory.  I thought it would be no problem, surely I can pass 
 the int[] to a Bitmap factory method which simply wraps it in a Bitmap 
 instance.  Unfortunately, this does not seem to be the case - 
 createBitmap(int[] colors, int width, int height, Bitmap.Config 
 config) seems to allocate its own int[] and copy the passed in int[] 
 into it, which fails if there is no memory for another copy. 

 I simply need to turn the image stored in the int[] to a .png on 
 external storage so actually any of the following would be good enough 
 for me: 

 - as mentioned above, a way to create a Bitmap so that it doesn't try 
 to allocate another useless copy of the data 

 - an accessor on Bitmap to return the Bitmap's pixel store as an int[] 
 (that way I wouldn't have to allocate my own int[] and would be able 
 to write directly into the Bitmap-owned memory) 

 - a way of accessing (an equivalent of) Bitmap.compress() 
 functionality without having a Bitmap 

 Amazingly, none of the above seems to be available!  Bitmaps tend to 
 be large objects in memory, surely there must be ways to handle them 
 in a memory-efficient manner... 

 Cheers!

Re: [android-developers] Tab Widget issue


 Hello to all, I create 3 intents of activities(which i add to TabHost) in

So far, so good...

I also have refresh and logout button with onClick method. When this button
 is clicked say refresh i want to refresh item of intent activity.

Where are these buttons?  What is item?

I just put an public method there, it's working fine if i say print any
 message there, but as I called some process method to get data from web
 service it;s not work.

You put a public method where?  What do you mean by called some process
method to get data from web service?  What do you mean by it;s not
work?  Care to elaborate at all?

To intent i use
 intentAccount.putExtra(test, Hello);
 AccountActivity r = new AccountActivity();
 r.update();

When do you use this?  Why are you creating a new instance of
AccountActivity every time?


 any one have idea what can done in this case ?

 We have an app on the market for a while now, mostly it works great. But
 recently we got a couple report that it force closes on some devices, since
 we don't have those devices to debug the problem, I hope I can ask the
 question here and maybe someone can share some lights about what we should
 do.

 The basic problem is that we have an activity A, which has a button for
 people to configure some information. So, we have an Activity B which
 collects those information. So, user click the button and Activity B will
 pop up, after users finish the settings, they click finish button or cancel
 button there and Activity B closes and Activity A has a onActivityResult
 call which collect which button was clicked and will adjust some
 information. But this force closes on some devices after user click either
 button.

 We added some debug code in onActivityResult but it finished the call to
 the end without crashing, so, we have no idea what other function should be
 called after that. We don't have onResume function in Activity A because we
 thought since we don't care about it, it should just use the default
 implementation. And we do have onSaveInstanceState function. So, one user
 who has this problem is willing to test anything or we can add debug code
 to anywhere, but since onActivityResult returns okay, we have no idea what
 to do next.

 Any suggestions about how to figure this out without the actual device to
 hook up the debugger?

 Thanks

Could you use setPixels(int[]) instead?

  As far as I know that allocated array

  That probably only happens when you alter the pixel data from Java. Which
  means that the get and setPixel methods must be really slow because in
 worst
  case they can cause heavy copy operations between JVM and native code for
  each access.

 I tried in the meantime to fill my large Bitmap by calling setPixel()
 on each of its pixels and the running time is in the order of tens
 seconds.

  The only other option that comes to my mind for speeding up things would
 be
  writing some NDK code and using a PNG library for encoding the pixel
 data in
  native code. Passing that int array to that native code is
 straightforward.
  With a trick you can even access the original Java int array directly
  without waiting for a copy. This is possible with the JNI function
  GetPrimitiveArrayCritical. There is no guarantee, though that direct
 access
  works in any case. The documentation of that function explains the limits
  pretty well.

 I don't use NDK in this app, was meant to be pure Java, however as
 there are other (performance) problems with bulk GL data handling that
 apparently cannot be solved without native code, I might consider NDK
 as well.

Re: [android-developers] Re: Calender view

Ok, your question is hard to understand, but I assume you are the same guy 
who was asking several times all over the past week for how to create a 
calendar week selection view, so I think you want to have a widget that 
allows the user to pick a week of the year.

The Java 
Calendarhttp://developer.android.com/reference/java/util/Calendar.htmlclass 
should give you enough material for figuring out the steps necessary. 
Another question you may want to answer yourself is: how do you want to 
present your week of the year selection? You can get an idea for that by 
playing around with the Windows 7 date selection widget, which does a 
pretty good job.

I would implement that as a separate view instead of trying to extend the 
existing calendar view of your choice with that function, because that may 
turn out to be too complicated. But the most elegant solution would be 
adapting that android calendar view source code for your needs.

You could create a ListView or GridView and set a custom Adapter that lists 
the week of the year. When showing that view you need to set the current 
selection to the current week (or any pre-selected week). The current week 
can be retrieved with a Calendar object:

Calendar cal = new GregorianCalendar();
 int weekOfYear = cal.get(Calendar.WEEK_OF_YEAR);



If you want to select the week of month instead then change WEEK_OF_YEAR to 
WEEK_OF_MONTH. In that case you need to have just 4 buttons anyway and 
don't need to bother with a ListView and an adapter.

  I think there is a bug here because it assumes device.getName() does not

  What do you guys think?

[android-developers] Re: OutOfMemoryException

2012-07-09 Thread Steve K.

Hello,

The framework (and support library) contains a class that you might find 
useful LruCache ;)

I will also highlight this training section
http://developer.android.com/training/displaying-bitmaps/index.html

BTW, if your know your application will use a lot of memory, you should 
query for heap size at runtime using 'ActivityManager.getMemoryClass()'

Re: [android-developers] Re: creating Bitmap from pixel data without copying the data

On Mon, Jul 9, 2012 at 8:22 PM, Romain Guy romain...@android.com wrote:
 Could you use setPixels(int[]) instead?

I considered passing my int[] to setPixels() but (correct me if I'm
wrong) that wouldn't remove the problem where at some point, the
bitmap data has to exist in two copies.

However, I probably could use setPixels(int[]) and pass subimages
several times until the whole bitmap is filled.  Yes, I'll check that
out, sounds like a good idea.

Thanks!

You are using asmack I suppose for the chat application.
You get all that you need for chat applications with XMPP.  And you
don't need to re-implement security etc.
(and it works with Gtalk and Facebook talk).

Anyway, you might want to have a look at AccountManager:

 Encoding a PNG will not require copying the PNG again so grab one with

Thanks, this didn't occur to me.  Just took a quick look, haven't
found anything suitable (should be free and take int[] on input) yet
but I'll try a more thorough search later.

Can you put tcpdump on the device to see if traffic is flowing?

Could you replace the ip addr with something on your local network to see

 *The setup*

 I have at home a wifi router under which I have my devices(couple of
 laptops,TV, Android phone and tablet). The router is connected to a cable
 modem provided by my ISP and all the devices share this connection.

 *Problem*
 Recently my ISP came up with an additional security system.On first
 connect(could be from any device) I need to authenticate myself with a
 username/password to my ISP website. I checked the system and they were
 intercepting the first http connection from my side and redirecting my
 browser to their login page. Some how my android browsers are not able to
 show this login page. I need to connect using my laptop and only later
 android devices can connect to internet.

 *My Solution*
 I wrote a small java application to over come this problem. It tries to
 connect to google.com. Intercept the redirect request and finally post my
 username password. The application is working fine with my laptop and I
 hooked it with windows start up and everything is great. Android devices
 still are not very happy with this app. On debugging I find that my very
 first socket connections is getting timed out and my application fails.

 *Technical Details*

 *Device *- Motorola Defy Plus

 *Android version* - 2.3.3

 *Exception Socket* - Time out

 *Code*
 public class SocketHttp {

 public static Socket connect(String ip) throws Exception {
 Socket socket = new Socket(ip, 80);
 return socket;
 }
 .
 }

 As I have not logged in to my ISP I am not depending on the DNS service
 and directly hardcoding a google.com IP.I have added
 uses-permission android:name=android.permission.INTERNET / in the
 Android Manifest. The code works correctly if the ISP login is completed
 using my lap top.

 Any idea what is going wrong?

This is the problem I am facing now. :(

It is the same for Android 3 (HTC Jetstream) and Android 4 (Galaxy Note)

Detected portrait and set it to portrait and the result is a reverse 
portrait if you are holding it wrong.

 This method has a problem in Android 2.2 which cannot detect the

[android-developers] Re: Lock orientation once the app started?

I am doing a painting program for kids.

- you wanted to show the kids the correct orientation when you enter the 
app, if you happened to hold a tablet in landscape, it is expected that the 
program started in landscape.

- but once you started painting, nothing is more wrong (at least to all the 
test subjects) than the painting accidentally rotate... and kids hand are 
not steady!

 We have an app on the market for a while now, mostly it works great. But
 recently we got a couple report that it force closes on some devices, since
 we don't have those devices to debug the problem, I hope I can ask the
 question here and maybe someone can share some lights about what we should
 do.

 The basic problem is that we have an activity A, which has a button for
 people to configure some information. So, we have an Activity B which
 collects those information. So, user click the button and Activity B will
 pop up, after users finish the settings, they click finish button or cancel
 button there and Activity B closes and Activity A has a onActivityResult
 call which collect which button was clicked and will adjust some
 information. But this force closes on some devices after user click either
 button.

 We added some debug code in onActivityResult but it finished the call to
 the end without crashing, so, we have no idea what other function should be
 called after that. We don't have onResume function in Activity A because we
 thought since we don't care about it, it should just use the default
 implementation. And we do have onSaveInstanceState function. So, one user
 who has this problem is willing to test anything or we can add debug code to
 anywhere, but since onActivityResult returns okay, we have no idea what to
 do next.

 Any suggestions about how to figure this out without the actual device to
 hook up the debugger?

 Thanks
