You probably forgot to override getViewTypeCount() and
getItemViewType() on your Adapter.

Re: [android-developers] Does it make sense to recycle views in a pager with not scrollable grid views?

The built-in implementations of PagerAdapter do not recycle AFAIK.

 I'm wondering if it makes any sense to use recycling functionality in this

 in the page (all items are visible, no scrolling).

 The reason of the question is that I would like to switch between 2
 different (similar) XMLs to inflate the items in the grid view. And, using
 recycling, it's probably not possible. But I think recycling is not
 necessary in this case.

Hi,

You don't understand. This is for very young kids - all the menus are for 
parents (save pictures, etc). The canvas needs to be full screen.

In the past this works perfectly as the menu is in a hard button.

[android-developers] Re: Forcing lower resolution drawables on phones with big screens and small RAM

2012-07-14 Thread Nobu Games

How many items are in your animation list? If it is really, really huge I'd 
add some streaming logic to your animation player, so older frames get 
recycled while future frames are loaded in the background. That way you 
have absolute control over a moving window of frames and you could size 
that window according to the available amount of free memory. You wouldn't 
risk OOM crashes on any device with that technique.

Alternatively you could create a video based on your frames and play that 
one back instead.

I know they will - but what can we do? The navigation bar is already there. 
Not having a menu is another option (our iPhone version use shake to show 
menu), as other options you mentioned...we have tried.

 That does not preclude having some sort of menu button in a corner. It 
 also does not preclude bringing up a menu based on some other trigger 
 (certain tap sequence in a corner, certain gesture, etc.). 

  
1st option still take up space in canvas. The trigger part is interesting. 
Tried shake but user does not like. Gesture will interfere with the 
painting as the kids constantly use their fingers to draw stuffs, so you 
can't be sure whether it is a dot or long press, a multitouch gestures (to 
draw lines) or trying to execute a command.

Anyway, do you know whether it is possible to show Action Bar only on 
tablet? That's the solution I am currently looking for.

Your solution is unsuitable for production apps. It may not work
reliably today. It will not work reliably in the future. You were
already told, personally, by a Google engineer, not to do this --
quoting Ms. Hackborn:

 The menu at the bottom is for compatibility with old applications.  You 
 should not be relying on it with new applications.

 Put an affordance somewhere in your UI to invoke this thing.  The menu button 
 is no longer a guaranteed affordance.

You even claim to have read what she wrote, as you replied to her message.

Many well-rated finger paint applications for Android, specifically
for use by very young kids, use on-screen controls, as you can tell
if you research your competition.

Mark, with all due respect, don't go this way.  Don't succumb to the
arrogance of thinking you can design limtc's app for him.

I have experience with a broadly similar type of app as his.  I can
tell you you can't always stuff controls to the screen, just because
someone somewhere at Google made an arbitrary decision to exclude
off-screen controls.  Sometimes on-screen controls get in the way,
sometimes they break immersion, sometimes there is no good way left to
bring them up if you hide them (this probably happens more often than
you think) sometimes there are other reasons neither you nor I have
ever thought of.

There are work-arounds but they are just that - work-arounds.
Bringing up UI is a fundamental concept, especially on mobile
platforms where screens aren't big enough for keeping UI displayed all
the time.  It serves nobody if one app has an on-screen button to
bring up UI, another does it via a shake and yet another uses an
obscure gesture because it uses every other possible option for
something else.

The Menu button was a uniform way to do something that 90% of apps
have or want to do.  Now everybody has been left to their own devices.
 As I haven't ever heard pretty much *any* reason for that, good or
bad, I tend to think dumping it was rather a boneheaded idea.

 Your solution is unsuitable for production apps. It may not work
 reliably today. It will not work reliably in the future.

The final call on this hasn't been done for us yet, but I'm telling
you - if need be, I'd rather have an app that works (and sells) great
for a year on a current Android version and possibly deteriorates
afterwards, than something that's clumsy and counterintuitive from the
get-go but can keep up its clumsiness unchanged to Android 38.3 or
whatever the current version will be in 2035.  I'd hate to have this
decision pushed onto me but that's what I'd prefer in that case.

[android-developers] Tokens

2012-07-14 Thread Mario Bat

Hi, I have to make an app where i send my device token to a server. The 
server is a Push server that will push notifications to the mobile device 
later. 

My question is; What are tokens and how do you create them? Does the server 
create my token or who? I know that for the Facebook API Facebook makes the 
token for you. So does every token creation work like that?

[android-developers] How to prevent resizing and relayout the window when soft keyboard displaying

2012-07-14 Thread dreamtale



I show an edit dialog in an activity, when the soft keyboard displaying, 
the window of the activity will be resized to too samll which looks awful. I 
don't want the window of the activity be resized and layout. I just want 
the keyboard can cover on the activity window and the dialog move to the 
top so that soft keyboard have room to show.

I have tried to use *android:windowSoftInputMode=x* in the manifest, 
but there are no one mode which fit my situation. I also found the similar 
questionhttp://stackoverflow.com/questions/5180789/android-how-to-prevent-resizing-the-window-when-displaying-the-virtual-keyboar,
 
but it did't solve my problem.

*EDIT:* I have tried setImeOptions and also getWindown().setFlags but it 
still did't worked, Any advice will be very appreciated

I know you are right and R class should be autogenerated, but it doesn't.
The gen folder is empty.

 If the file is not being generated, may be there is some other problem

 Google for R cannot be resolved into a variable, there is a lot of

[android-developers] Wifi Only tablet missing NetworkProvider

2012-07-14 Thread RE

I bought this wifi-only inexpensive tablet (see the build.props below). It 
has a fully operational wifi to get on the network and do what one would 
expect. I wrote a bit of code to explore what location providers were 
available on the tablet. According to the responses, the only available was 
GPS_PROVIDER. However, I have never gotten a GPS fix. The tablet is Android 
4.0.3. I ran the same code on my cell phone (Android latest 2.3) and it 
worked as expected when the cell service was disabled. It showed location 
and gps. I turned off gps and it just showed location. 

Why is there no network_provider available on this tablet? Is there a 
plugin/driver that is missing? I thought network_provider worked via the 
network only (Wifi - i.e.: firefox on laptops). Since it is an inexpensive 
tablet, why would it come with an additional radio for GPS and not support 
a feature for the radio it advertises (Wifi)? Is there something I am 
missing with regards to Wifi-Only tablets? Is it the ROM? This tablet is 
from China (HK) perhaps it's disabled for export? I bought this thing 
specifically to write a location based app without using my phone.

Thanks,
E

(Build.props are attached)

[android-developers] Different Screen Sizes and Resolutions

2012-07-14 Thread Bradx

Hey guys!

I am a new developer, and I have been working on my app the past week or 
so. So far I have it looking good and working fine, but my employer wants 
me to make it run on screen sizes from normal to xlarge and densities from 
medium to xhigh. I found a document on the developer's website about this, 
but it said that I should have different pictures and layouts if I want to 
do it right.

I know it said that the phone will scale it up or down depending on what it 
can support, but it didn't suggest that because of artifacts forming, which 
I don't know what those are.

So, I was wondering if you all could help me out a bit, and lead me in the 
right direction. I want to do some of the work, just so I can learn, but a 
little help is nice every now and then.


Thanks!

- Brad

you have to call it after internal layout has been built - you can for
example post runnable after calling setText() - doing so you make sure
the internal layout is built

[android-developers] Before I start, a question regarding google maps traffic

2012-07-14 Thread CreepyD

I hope someone can help here.
I have an app idea, but want to know if it's possible before I spend lots 
of time learning how to make apps.

Is it possible to 'plug-in' to google maps traffic based on a specific map 
point?
e.g. If I want to check what the current traffic is at an exact point along 
a road? (using code, not looking at the map manually).
So it would simply tell me if it was green/yellow/red etc right now based 
on the position I gave it to look up.

Or is the traffic information literally just an 'overlay' that I can't 
interact with with code?

If nobody knows, where would I find this information?  Google doesn't seem 
to have the answer.

Thanks!

[android-developers] Cheapo Chinese tablet missing NetworkProvider

2012-07-14 Thread RE


I wrote some code to discover the location providers available. I ran the 
code on my phone (with cell off, gps off, and wifi on). It found the 
NetworkProvider. Turning on GPS it found them both. (cell is v2.3.3)

So I thought that NetworkProvider would be valid for anything that has WiFi 
or network connections. However, I noticed that the cheapo $100 tablet 
(from China based on the build.props file) doesn't have NetworkProvider. I 
understand if NetworkProvider is there, all we need is a network 
connection. However, it reports that the GPS exists, but it's never 
reported a fix. I understand that GPS requires a different radio, and if 
they're as cheapo as they say, why include a GPS chip and not enable 
NetworkProvider considering that they already have wifi built in. (tablet 
is v.4.0.3)

[android-developers] Wifi-Only tablet missing NETWORK_PROVIDER!?

2012-07-14 Thread E. Recio

I bought this wifi-only inexpensive tablet (see the build.props below). 
It has a fully operational wifi to get on the network and do what one 
would expect. I wrote a bit of code to explore what location providers 
were available on the tablet. According to the responses, the only 
available was GPS_PROVIDER. However, I have never gotten a GPS fix. The 
tablet is Android 4.0.3. I ran the same code on my cell phone (Android 
latest 2.3) and it worked as expected when the cell service was 
disabled. It showed location and gps. I turned off gps and it just 
showed location.


Why is there no network_provider available on this tablet? Is there a 
plugin/driver that is missing? I thought network_provider worked via the 
network only (Wifi - i.e.: firefox on laptops). Since it is an 
inexpensive tablet, why would it come with an additional radio for GPS 
and not support a feature for the radio it advertises (Wifi)? Is there 
something I am missing with regards to Wifi-Only tablets? Is it the ROM? 
This tablet is from China (HK) perhaps it's disabled for export? I 
bought this thing specifically to write a location based app without 
using my phone.


Thanks,
E

[android-developers] Re: adk 2012 / usb accessory not connecting

2012-07-14 Thread Doug

Joe,

Well, the first thing that irked me was the fact that the board needs a USB 
driver installed, or OSX won't even recognize the board's presence.  This 
was documented nowhere.  I had to hunt it down myself.

No problems with Java here.  The IDE launches fine and I can load source 
files into it.  It just couldn't compile the clock sample out of the box.  
It could never find the first ADK include.  It's been a while, so I don't 
remember those details off the top of my head.  I did have the board 
selected in the menu, but I can't imagine that would make much of a 
difference because the IDE is special for that board.  On the ADK web site 
there is installation step which made no sense to me:

Copy the adk-source-download/adk2012/board/library/ADK2 directory and its 
contents into your sketchbook/libraries/ directory, so that you create a 
sketchbook/libraries/ADK2 directory.

I didn't see anything at all about a sketchbook/libraries directory in the 
real world.  I'm assuming this step was meant to get the ADK libs into a 
place where they will be used by the clock demo or whatever program you're 
writing.  I tried to make up a bunch of possible locations to put these 
files, but no dice.  Maybe they are assuming the reader has prior Arduino 
experience, which I do not.  I was eventually able to get the clock demo to 
compile, but after deployment it locked up the hardware.  I think it wasn't 
actually building the ADK libs with the sample code.

So I switched to the command line tools.  On the command line (using the 
git source repo), when trying to build and deploy it told me I needed 
bossac and gave me a url to find it.  So I went and got it, but the OSX 
exe never once recognized the board.  The bossac exe that comes with the 
IDE does work, however, so I wedged that one into the command line build 
process.  The command line build still had troubles finding the ADK headers 
and sourced needed to build, so I had to copy all those manually into the 
clock demo source tree, then I was finally able to build and deploy.

I'm on OSX Lion on a Mac Mini if that makes any difference.

 Hey Doug,

 What problems did you run into using the Mac IDE for the ADK2? I just 
 finished installing the ADK IDE and managed to upload the clock sketch. I'm 
 using a Mac Air with OS X v10.6.8.

 Couple of things I found that were a little tricky:

1. For some reason, my Mac's Java installation got hosed recently and 
I had to update to Java 1.6.0_33. After the update my Arduino IDEs (along 
with the ADK 2012 IDE) started working again. Prior to that update, I 
couldn't even get the IDE to run, error: No compatible version of Java 
1.5*
2. Make sure to you plug into the Computer micro USB port (not the 
Phone port)
3. Choose the correct serial port in the IDE, *Tools  Serial Port* (my 
Mac Air gave me 6 options) the correct port was 
 /dev/tty.usbserial-XXX
4. Choose the board *Tools  Board  Google ADK2*, otherwise the 
sketch won't even compile.

 This isn't the right place for ADK discussion, but as far as I can tell, 
 there is no place set aside for it!

 I killed a lot of today trying to get the 2012 ADK to work and was mostly 
 frustrated.  I'm on a Mac and I found the IDE installation instructions 
 very much do not work and I could not manipulate it into building and 
 flashing a working image at all.

 On the command line, I had to jump through hurdles to get the clock demo 
 to build and deploy.  In the end, I could not get recommended bossac 
 downloaded from sourceforge to work at all.  Eventually I had to bypass the 
 given scripts and reached into the Mac IDE app package to use its bossac to 
 deploy a working image.

 All things considered, I'm very disappointed in the usability of the 
 tools that were provided for the 2012 ADK (at least for macosx) and I wish 
 I knew where to go to remedy this.  Otherwise I pretty much give up now.

[android-developers] Re: Programatically setting Linear Layout parameters i.e. Wrap_content and match parent

2012-07-14 Thread marcpolo

Didn't realise that you can simply replace WRAP_CONTENT with a fixed width. 
Problem solved.

On Wednesday, 11 July 2012 20:24:31 UTC+1, marcpolo wrote:

 Hi,

 I'd like to have two views within a horizontal linear layout and 
 programatically align them as follows.

 View A should be of fixed width on the left hand side and View B should 
 fill the remainder of the space. I tried setting the following layout 
 parameters

 ViewA.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, 
 LayoutParams.MATCH_PARENT, 0));
 ViewB.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, 
 LayoutParams.MATCH_PARENT, 1));

 Whenever I set the weight of ViewA to 0, only ViewA is displayed. I 
 expected a value of 0 to mean that ViewA doesn't get stretched.

 When I set ViewA::Weight = 4, and ViewB::Weight = 1, ViewA is a quarter of 
 the size of ViewB. I expected the reverse.

 WRAP_CONTENT  seems to have no effect.

 This seems straightforward when using the manifest file, however I am 
 modifying existing code that requires me to set these values 
 programatically. Could someone help me.

 Thanks in advance.

[android-developers] Jelly Bean Crash with Bitmap Recycle Sorry, an error has occurred: bitmap is recycled

2012-07-14 Thread Craigo

Hi Google,

My app that has been running for over 2 years without an update, finally 
broke with Jelly Bean.  The error: Sorry, an error has occurred: bitmap is 
recycled.

The problem was with calling recycle on a bitmap:

Bitmap bitmapOld = bitmap;
bitmap = Bitmap.createScaledBitmap(bitmap, newWidth, newHeight, false);
bitmapOld.recycle();

Note: I never referenced bitmapOld again.

The fix was easy, I just don't recycle any more.  However, it seems odd 
that this would have broken.  Maybe creating the scaled bitmap shares 
memory with the unscaled bitmap?

Anyway, hopefully this information is useful to someone.

Cheers, and keep up the excellent work!

Re: [android-developers] Re: static vs non-static inner classes

2012-07-14 Thread Michael Rozumyanskiy

But what about a Handler.Callback interface which can be passed to the 
Handler's constructor. According to the source code it is stored in the 
Handler class as a strong reference, so if the Message lives in the queue 
for a long time, the callback will not be gc'ed. And the callback may be an 
Activity or an inner class of an activity. But I can't see any checks in 
the source code and any recommendations in the documentation. As far as I 
understand, there isn't any right way to use the Handler.Callback with the 
Handler, is there? 

On Saturday, April 4, 2009 9:52:06 PM UTC+4, Romain Guy wrote:

 I wrote that debugging code because of a couple of memory leaks I 
 found in the Android codebase. Like you said, a Message has a 
 reference to the Handler which, when it's inner and non-static, has a 
 reference to the outer this (an Activity for instance.) If the Message 
 lives in the queue for a long time, which happens fairly easily when 
 posting a delayed message for instance, you keep a reference to the 
 Activity and leak all the views and resources. It gets even worse 
 when you obtain a Message and don't post it right away but keep it 
 somewhere (for instance in a static structure) for later use. 

 If you want to use the equivalent of an inner-class but not risk a 
 leak, here's a simple pattern: 

 class OuterClass { 
   class InnerClass { 
 private final WeakReferenceOuterClass mTarget; 

 InnerClass(OuterClass target) { 
   mTarget = new WeakReferenceOuterClass(target); 
 } 

 void doSomething() { 
   OuterClass target = mTarget.get(); 
   if (target != null) target.do(); 
 }

  Thank you very much for the reply! After reading what Fadden said 
  weeks ago, I happily converted my static inner handler classes to non-

  Just recently, I was browsing the source code of Handler and came 
  across this bit of internal Android debugging: 
  
 /* 
  * Set this flag to true to detect anonymous, local or member 
  classes 
  * that extend this Handler class and that are not static. These 
  kind 
  * of classes can potentially create leaks. 
  */ 
 private static final boolean FIND_POTENTIAL_LEAKS = false; 
  
  There is some code further down that uses reflection to locate such 
  subclasses if this flag is true. 
  
  My handlers fall into the category of non-static member classes, so I 
  am curious how such classes could cause a memory leak. My initial 
  thinking was that handlers could perhaps accumulate in a collection 
  associated with the MessageQueue. But handlers are never placed into 
  collections, as far as I can tell. The reference to the handler is in 
  the message. Clever! (And in any case if the memory leak is due to an 
  ever-growing collection of handlers somewhere then that has nothing to 
  do with whether or not the handler class is static or not.) 
  
  Just wondering if someone can shed some light on this comment in the 
  Android source code.

  Staticinner classes have some useful properties, e.g. you know

  Class.newInstance() with them.  There's no performance magic though. 
  
  If you're really curious, write it both ways in trivial source files,

[android-developers] Handler.sendEmptyMessageDelayed() unreliable on some versions of OS?

2012-07-14 Thread mapeters

I have a thread (guts implemented as a subclass of Runnable) whose job is 
to perform an operation on demand from other threads or automatically every 
two minutes if no other thread invokes the operation. The run() method of 
this Runnable calls Looper.prepare(), creates a Handler object in a member 
variable, uses that to call sendEmptyMessageDelayed(1, 3000), then calls 
Looper.loop().

Other threads use a method in this thread's public API to invoke its 
operation. That method just calls the handler's sendEmptyMessage(0) method 
to invoke it. When the handler's handleMessage(Message) method is called, 
it acquires a lock (ReentrantLock), calls the handler's 
removeCallbacksAndMessages(null) method and performs its operation (within 
a try/catch block). The finally section of that block calls the handler's 
sendEmptyMessageDelayed(1, 12) method then releases the lock.

This works fine on every device I have tested it on, and by everything I 
know, it is a valid way to do this that ought to work on every version of 
Android OS. Recently, however, somebody claimed it wasn't running every two 
minutes as it should, and gave me the log file it produces to prove it 
(which it does). That log shows that sendEmptyMessageDelayed(1, 12) was 
called, and then 11 minutes later, the handleMessage(Message) method was 
called. I know this invocation of handleMessage() was in response to that 
sendEmptyMessageDelayed(1, 12) call because Message.what was 1 (a value 
used only by the sendEmptyMessageDelayed() call).

How is this possible? I could understand the timing being off by a few 
seconds, but 11 minutes? In subsequent attempts to reproduce this, I have 
seen that timing being off by 45 minutes and more. This problem has been 
observed on an HTC One X running Android 4.0.3 and a Samsung Galaxy SII 
running OS 2.3.6.

Has anybody else seen this issue? Does anybody have a suggestion for what 
might be causing this? My current position is that this is an OS bug, but I 
am loathe to just accept that and call it a day. BTW - just for kicks, I 
temporarily re-implemented this using a Timer object instead, and observed 
exactly the same problem (using Handler is a better solution anyway).

Thanks,

Mark Peters

 It's a weird choice the one to do not support natively this protocol,

 Since the world is not made by USA only, why not to implement this

 Unless we have to pay respect to skype, there is no reason to trash 
 the 3G-324M videocall. Skype needs internet coverage, an included data 
 plan, and basically needs the internet access on the receiper side who 
 has to be online... too many coincidences to make it an elegible 
 choice of videocall. You need to agree before the videocall, e.g.: 
 hello, how are you? I''ve got internet coverage and I can pay for it 
 for a while, are you on internet with your device? Can you login on 
 skype? Are you logged in? Ok I'm videocalling!.. OMG, no 
 way! 
 With 3G-324M you can just videocall and that's it!!! So, plz implement 
 this protocol natively in Android.

[android-developers] Run application with system / root permissions.

2012-07-14 Thread Jordi Sayeras

Hi,


I've been searching about this topic but I haven't found a clear solution
yet. As far as I know, you can specify different *protectionLevel* in your *
AndroidManifest.xml*, those permissions allow other applications to
interact with the one you are developing. As an example, imagine that I
want to kill a processes, that is not mine (from another package) or that I
want to install a driver I've developed. In both cases the problem is the
same, those things need to be run as a system / root. How can I develop
programs that require system / root permissions, do I need an special
license?



*Note:* Please, note that granting the permission:



*uses-permission
android:name=android.permission.KILL_BACKGROUND_PROCESSES/*



Using *android:sharedUserId=android.uid.system* does not work either.



Also, consider that I cannot ask the users to have their mobiles rooted.



Thanks in advance.



Jordi.

[android-developers] Creation of 'native' objects on the other end of the binder proxy

2012-07-14 Thread Chethan Palakshamurthy

Hello,
I am going through multimedia framework, and while most things seem fairly 
clear to me, the creation of the 'native' objects (or BnXxxx objects of 
binder framework) seem perplexing to me. I just can't find where those are 
created!!

The proxy objects are created with a hard to find new Bp##INTERFACE macro, 
but that's not the case with the objects on the server. For e.g., I can't 
find the instantiation of BnMediaPlayerService on MediaServer. Lxr 
http://androidxref.com/4.0.4/search?q=defs=BnMediaPlayerServicerefs=path=hist=project=abiproject=bionicproject=bootableproject=buildproject=ctsproject=dalvikproject=developmentproject=deviceproject=docsproject=externalproject=frameworksproject=hardwareproject=libcoreproject=ndkproject=packagesproject=prebuiltproject=sdkproject=systemthrows
 
me just the declaration.

Unfortunately I don't have a full setup to view the full call stack and 
find out myself. Could any one point me where such objects are created? Is 
there some code that is not part of the SDK that could be instantiating 
them?

Thanks in advance,

[android-developers] Re: READ_LOGS permission is not granted to 3rd party applications in Jelly Bean (api 16)

2012-07-14 Thread nnk

There's no documented, approved way to read the log entries.

Having said that, if you just exec() logcat, as you did before, you'll
automatically get your own log entries. You don't need to do anything
special. The log system knows which log entries belong to you, and
which log entries belong to others, and will only give you your log
entries.

command-line switch on logcat to limit output to just your own

[android-developers] Where to start?

2012-07-14 Thread Mitchell Just

Hi guys,

I'm trying to put together a fairly simple application, but I'm getting a 
little overwhelmed at the moment. I've read through most of the Google 
tutorials, and a heap of stackoverflow threads, but I just seem to be going 
around in circles.

Basically I have a Java application running on a server, which sends out 
and responds to JSON messages over sockets.

The app needs to be able to send messages to the server, and also be 
listening for update messages to update the gui accordingly.

Would the best way to do this to make a Service which handles a socket to 
the server?

I assume the server would need a separate thread for reading from the 
socket.

If someone could point me in the right direction, that would be awesome.

Cheers,
Mitch

[android-developers] How to stop terminate the Android application when using the native code

2012-07-14 Thread Clark kent

Hello every body

I have this problem which can not resolve it. 

I'm calling the native code(*C code*) from the android application. But in 
the native code, they call function *exit(0)* so it makes the app on 
Android terminate. Could any one know how to stop this one, because after i 
called one method from native code , after it finished, it will terminate 
the Android application.

I found a way is disable the method *exit(0)*, so it will not terminate 
the Android app, but it meet error when i called the native method second 
time, some error kind like this: *Invalid heap address in internal_realloc*. 
I think that came from the re allocation the memory. So if any one know how 
to free all memory of native call, please let me know. Thanks for any 
comments

Thanks

Clark

Hi,

@Justin,

I have an Samsung Galaxy version 4.0.2. I wrote an app that receives 
multicast packets. But it doesn't receive any. My router doesn't filter 
multicast packet. I have added the necessary permissions and acquire a 
multicast lock. It seems the main reason is that the phone doesn't send out 
an IGMP message to join the multicast group. Is there any thing that I need 
to do on the phone.is IGMP implemented in Samsung Galaxy Nexus Version

is that why no IGMP message coming out of my phone. You help would be very

Re: [android-developers] why is the account managed by AccountManager is delete automatically ?

2012-07-14 Thread Mathias Roth

Some of my users are experiencing the same issue. My suspicion is that the 
default install location changed from internal to external on 4.1.1. At 
least one user reported things are working with

android:installLocation=internalOnly

set in the manifest. This should be default behavior according to API-doc, 
but it seems like it isn't on 4.1.1.

Re: [android-developers] Showing Action Bar ONLY on tablet?

On Sat, Jul 14, 2012 at 1:47 PM, Latimerius l4t1m3r...@googlemail.com wrote:
  As I haven't ever heard pretty much *any* reason for that, good or
 bad, I tend to think dumping it was rather a boneheaded idea.

I can't speak to why they elected to grant device manufacturers the
freedom to skip off-screen controls. For all I know, it is YAAP (Yet
Another Apple Patent). However, that does not change the fact that
they *did* give device manufacturers the freedom to skip off-screen
controls.

Now, if all finger paint apps for children on Android got low ratings
and had on-screen controls, I would at least entertain the notion that
correlation might indicate causality, and the on-screen controls were
the source of the low ratings. However, a quick glance at the search
results and examining the screenshots indicate that there are several
finger paint apps for children with on-screen controls *and* 4-star
ratings (and on 1000+ ratings, not just a handful). To claim that
on-screen controls are somehow impractical for finger paint
applications for children, therefore, seems to be inaccurate, and
creating an intentionally future-resistant finger paint application
for children just to avoid on-screen controls is not wise.

Furthermore, it is ludicrous to think that a child will somehow tap on
some on-screen control, yet not tap on a menu affordance in the system
bar nor click on a dedicated off-screen MENU button. If anything, a
well-designed on-screen control could be *less likely* to be
accidentally invoked than would legacy menu affordances, by making it
slightly more challenging to trigger than just a tap (e.g., physically
smaller, tap-and-hold, tap-and-slide). While it is impossible to
prevent a child from doing any of these things, you actually have
control over an on-screen mechanism that you do not have for anything
else and therefore can take steps to reduce the odds.

If the issue is aesthetics, make the on-screen control invisible,
perhaps appearing after a period of inactivity or after the screen has
turned off and back on. You could even make the on-screen control
simply be not there except after inactivity or a screen off/on cycle,
so that a parent can readily get to the control after retrieving the
device from the child. Or find other ways of solving the problems
formerly handled by an in-app menu (e.g., auto-save after inactivity,
so the parent does not need to explicitly save from the paint activity
but can go into a separate activity to review saved pictures and
remove them).

And so on.

Now, I cannot speak for your app, because I don't know what it is.
Perhaps you could consider submitting it for the developer relations
Friday App Review thing, specifically asking for ideas for how to
address your variant on this issue, and try to get Googly input on the
matter that way.

It is crashing either due to a bug in your app or due to a bug in the
device. However, since you did not provide any details (e.g., stack

what may be going on.

Possibly. That is difficult to answer in the abstract.

However, if your objective is to deliver these messages at any time,
without the user necessarily being in your app, please try to switch
to Google Cloud Messaging. Otherwise, you would need to try to have a

 Bug is still present in R16
 WXGA emulator does not work, even changing device ram site to 512MB.

The WXGA800 and WXGA720 emulators definitely work on R16. I personally
run these emulator AVDs with 1GB of device RAM.

Note, though, that the current version of the tools is R20.

Re: [android-developers] Wifi-Only tablet missing NETWORK_PROVIDER!?

 Why is there no network_provider available on this tablet?

You would have to ask the device manufacturer.

 Is there something I am missing with regards to Wifi-Only tablets?

The so-called network provider uses either WiFi hotspot proximity or
cell tower triangulation. The latter is definitely not possible if you
lack the chips to talk to cell towers. The former assumes that there
is a back-end service provider with location data for hotspots, such
as Google or Skyhook Wireless. Perhaps your device manufacturer does
not have deals with such a service provider.

[android-developers] custom layout on ListLayout can't be browsed using d-pad

2012-07-14 Thread Jeremy Villalobos

Hello:

I am checking my app is accessible.  In the course of doing this, I am 
using a d-pad to browse the app.  

I have a custom row on a  List Layout.  Each row follows the attached 
layout.

When I browse the layout using the d-pad I can only highlight 
the more_button_layout layout.  I cannot click on any button or layout. 
 I've played with the focus labels, but they don't have any effect.

I am using eye-free keyboard as the d-pad

Thanks for any help.

 If by the package you mean your APK, that is not supported.

Re: [android-developers] Showing Action Bar ONLY on tablet?

 Now, if all finger paint apps for children on Android got low ratings
 and had on-screen controls, I would at least entertain the notion that
 correlation might indicate causality, and the on-screen controls were
 the source of the low ratings. However, a quick glance at the search
 results and examining the screenshots indicate that there are several
 finger paint apps for children with on-screen controls *and* 4-star
 ratings (and on 1000+ ratings, not just a handful). To claim that
 on-screen controls are somehow impractical for finger paint
 applications for children, therefore, seems to be inaccurate

Who's to say how many 4-star ratings / downloads would a finger paint
app have that didn't have to clutter the screen?  Sadly, Android has a
reputation for low-quality apps.  People will sometimes give a good
rating just because an app to do such and such exists, no matter how
badly it does it.

Giving the user a good feeling about using a device/app is a very
tricky area.  I worked for the official games industry for 7 years and
I saw the attention these guys tend to give controls.  While not every
little Android app has to be as fine tuned as a twitch shooter, every
app should feel good - something Apple is famous for understanding.
You can't say that a painting app is good enough just because there
are still a bunch of pixels left for the actual painting after we've
rendered our UIs.

 and creating an intentionally future-resistant finger paint application
 for children just to avoid on-screen controls is not wise.

Again, that's for people who design/make a particular app to decide.
Very very few apps released this month will still get new downloads a
year from now, at least in entertainment which is what I'm interested
in, so risking that an OS version 3 years from now will break the app
might be a very sound business decision if the risk brings in
substantial benefits during the projected life cycle of the app.

 Furthermore, it is ludicrous to think that a child will somehow tap on
 some on-screen control, yet not tap on a menu affordance in the system
 bar nor click on a dedicated off-screen MENU button. If anything, a
 well-designed on-screen control could be *less likely* to be
 accidentally invoked than would legacy menu affordances, by making it
 slightly more challenging to trigger than just a tap (e.g., physically
 smaller, tap-and-hold, tap-and-slide). While it is impossible to
 prevent a child from doing any of these things, you actually have
 control over an on-screen mechanism that you do not have for anything
 else and therefore can take steps to reduce the odds.

You might well be right on this, however the decision to leave out the
Menu button is of a much much broader consequence than just finger
paint apps for children.  There are apps for which an off-screen
button is just *the* simple and natural solution, everything else is
kludgy work-around.  If there were no such apps at the moment, they
would appear in the future.

Saying no Menu button should be enough for everyone reminds a
similar well-known statement that concerned 640kB of memory -
supporting such claims you run an acute risk of getting on the wrong
side of history. :-)

 If the issue is aesthetics, make the on-screen control invisible,
 perhaps appearing after a period of inactivity or after the screen has
 turned off and back on. You could even make the on-screen control
 simply be not there except after inactivity or a screen off/on cycle,
 so that a parent can readily get to the control after retrieving the
 device from the child. Or find other ways of solving the problems
 formerly handled by an in-app menu (e.g., auto-save after inactivity,
 so the parent does not need to explicitly save from the paint activity
 but can go into a separate activity to review saved pictures and
 remove them).

This all depends strongly on the actual application.  Based on my
experience, you can't make any blanket statements like this. As stated
above, this is not just about kids' paint apps - it's not even just
about paint apps in general, although if you consider something like a
simplified Photoshop in your phone, you start seeing immediately that
none of what you propose would work.

Although I'm no artist by profession, I took drawing/painting classes
for couple of years and I can draw, sort of - and my bro is an artist.
 I can tell you a painting app that kept UI stuck on-screen all the
time would likely be a no-go.  The canvas belongs to the artist, it's
just ridiculous to make people paint around your UI.  Also, when
you're looking at what you've done so far, any UI would be annoying as
hell.  (I sat for some weeks next to concept artists a while ago (oh
the joys of open-space offices :-( ) and these guys even go to
full-screen all the time to gauge their work, often several times a
minute, although switching back and forth between windowed and

Re: [android-developers] Jelly Bean Crash with Bitmap Recycle Sorry, an error has occurred: bitmap is recycled

2012-07-14 Thread Romain Guy

Ah, this is an interesting bug that we ran into ourselves.
createScaledBitmap() can return the *same* bitmap if the scaled copy would
have the same dimensions as the original image. The proper way to do this
is to write:

bitmap = Bitmap.createdScaledBitmap(oldBitmap, etc...);
if (bitmap != oldBitmap) oldBitmap.recycle();

 Hi Google,

 My app that has been running for over 2 years without an update, finally
 broke with Jelly Bean.  The error: Sorry, an error has occurred: bitmap is
 recycled.

 The problem was with calling recycle on a bitmap:

 Bitmap bitmapOld = bitmap;
 bitmap = Bitmap.createScaledBitmap(bitmap, newWidth, newHeight, false);
 bitmapOld.recycle();

 Note: I never referenced bitmapOld again.

 The fix was easy, I just don't recycle any more.  However, it seems odd
 that this would have broken.  Maybe creating the scaled bitmap shares
 memory with the unscaled bitmap?

 Anyway, hopefully this information is useful to someone.

 Cheers, and keep up the excellent work!
