I already saw that presentation and I can't use the ViewHolder pattern 
because i need a customView. 

So I'm looking for a way to optimize my CustomView because I don't know 
what I'm doing wrong with this view that causing thoses GC

 The problem is : as I'm creating my custom view heriting from View, I

 And I'm already implemnting it with the view recycling view system. 
 Indeed, in my View I use some Paint elements that I keep in the instance of 
 my view.


 You have to refactor your code, so that you use all suggested 
 optimisations out there, but HolderPattern is a must. Recycling view 
 objects is build into the ListView, so use it, or be slow. Creating new 
 view object per item is going to hurt.

 Just read some articles, watch Romain Guy talks from Google IO and see 
 where you have gone wrong.

 Hi everyone, 

 I have a problem for optimzing my application. More particulary, an 
 ExpandListView. I found the scroll animation pretty slow compare to what 
 I 
 can see on other application. I have done severals optimizations yet but 
 now I'm faced to a lack of idea for have a fluent scroll...

 What have done : 

1. First i start to create CustomView inherting from View
2. I saw that in log I have lots of GC 
3. I have use allocationTracket in DDMS in order to see what are 
the object created who could cause my GC
4. I identify lots of instanciations of String so I've modify my 
model in order to carry all the string i need in order to avoid new 
creations of String 
5. I also try to write a reusable object corresponding to a 
drawable instruction in order to skim throught all instruction during 
 the 
draw method


 In order to gives you all information for helping me with my code, 
 here is a litle piece of functionnal.

 My app is an application which gives you the movies showtimes near 
 your position. The expand list show thoses informations :

  *Name Cinema :   [Image]
 *
  distance  
 ----
 --
 *Movie Name 1 :* time
 passed time 1 | passed time 2 | *nearest time* | 
 futur time 1 | futur time 2 
 --
 ---
 *Movie Name 2 :* time
 passed time 1 | passed time 2 | *nearest time* | 
 futur time 1 | futur time 2 
 --
 ---


 etc.

 As you can see, on each movie I list all showtimes for the cinema and 
 I have a diferent display according to the current time

 In term of Model Object, I have this structure in my adapter : 

 ArrayListTheaterBean theaterList; // The list of my cinema
 HashMapString, Movie mapMovie; // An hashmap which gives me the 
 movie corresponding to an id


 The problem I'm facing now is that when i look at the log, I still 
 have lots of GC... and when i looked to the allocationTracker i see that 
 :

 In first position comes android.graphic.Bitmap from method 
 nativeCreate and it's corresponding stack is : 

 android.graphics.Bitmap nativeCreate Bitmap.java -2 true 
 android.graphics.Bitmap createBitmap Bitmap.java 477 false 
 android.view.View buildDrawingCache View.java 6599 false 
 android.view.View getDrawingCache View.java 6450 false 
 android.view.ViewGroup drawChild ViewGroup.java 1571 false 
 android.view.ViewGroup dispatchDraw

Hi,

 Thank you for your reply. This is roughly the framework of code I
am using:

Main Thread :-

Handler handler = new Handler();
handler.postDelayed (runnable,miilisecs);

Another Thread :-

handler.removeCallbacks(runnable)

But I find that handler.postDelayed (runnable,miilisecs) still
executes after handler.removeCallbacks(runnable) is executed in the
other thread.

Thank you,
B.Arunkumar

That makes absolutely no sense whatsoever.

- TextView inherits from View

- your custom View subclass inherits from View

And:

- TextView works just fine with the ViewHolder pattern
- ImageView works just fine with the ViewHolder pattern
- CheckableTextView works just fine with the ViewHolder pattern

Hence, I am fairly comfortable that for any well-written custom View
subclass, the ViewHolder pattern can apply. There should be nothing

2012-07-03 Thread Kostya Vasilyev

A custom view, assuming it's at the root of your item layout, is just as
good as a view holder.

Here is what you can do:

- Override onFinishInflate in your item layout root view
- Call this.findViewById to find children
- Store them as member variables
- Access in the adapter's getView, like itemView.mText1, itemView.mText2 --
rather than doing itemView.findViewById(...)

[android-developers] Re: Handler removecallback problem

Does this happen every time or only occasionally?
Does your code call handler.postDelayed (runnable,miilisecs) in other 
places or repeatedly?
What is the value of miilisecs?

And finally there is a small chance that the runnable will be started just 
as you call  removeCallbacks due to threading.

if you call postDelayed after removing runnable it is normal that your

Re: [android-developers] Re: Problem optimizing views for having a fast scroll

Ok so can you please explain me how to do a view like this : 

--
*NameMovie*
1h20min
11:00am | 2:00pm | *4:00pm* | 8:00pm | 10:00pm
-

--
Text(in bold)
SubText(in gray)
Text1 (in gray) Text2 (in gray) Text3 (in bold) Text4 (normal)
-

I won't use viewHolder because my CustomView doesn't inherites from 
LinearLayout, I don't any xml file. I'm using a class that inherites from 
View.

Considerating that I don't know in advance how many Texts in gra, same 
thing for Text in bold and Text normal. AND I have to take care to cariage 
returns .

I first use this model : 

LinearLayout
  align:'vertical'

TextView id=movieName/
TextView id=timeMovie/
TextView id=showtimes/
/LinearLayout

And with the view holder pattern it works but I have low performance for 
the generation of the string : 11:00am | 2:00pm | *4:00pm* | 8:00pm | 
10:00pm because I need to use a HTML paint

So after talking with lots of people I decided to write my own View 
inheriting from View. The problem is : according to time of day, the view 
will show : 
11:00am | 2:00pm | *4:00pm* | 8:00pm | 10:00pm 
and after 11:00am | 2:00pm | 4:00pm | *8:00pm* | 10:00pm
etc.

And according to the couple movie / cinema, I don't have the same number of 
showtimes so I can't say that I will use 4 textView for the showtimes 
because it will be wrong for the next movie to print.

Or maybe I don't have understand how to use the ViewHolderPattern...
In my Adapter, I directly use the viewObjects. How can i use the 
viewHolderPattern if my view inherites from view and don't have any view 
element in it ?

That's impossible, indeed. Two different applications may have different

another free, is with different apps.

Re: [android-developers] How to: Free to Paid App and retain preference and db files?

If you use a SQLite3 db or so for preferences, you cannot access it from
different packages, but in some cases you can implement an export/import
mechanism, saving the preferences in a file into the external SD card.

My first app uses just a plain text file written into the SDCard and for
having same preferences in free and in per pay versions I just need to
use the same name for that file.

Currently I use an SQLite database, so I cannot do that so direct. But
to be honest I do not care. At least in my case it is not so important.

Your class inherits from View, therefore it has View.setTag() and
View.getTag(), to hold on to children Views within each list item. Each
list item has all those sub-views, but each of sub-views has a different
atributes (text, text color, ...) set durring each ListAdapter.getView().
This means that your convertView reference passed into getView will have
Tag object set with all your sub-views ready to be customised for the given
list element.


 Considerating that I don't know in advance how many Texts in gra, same
 thing for Text in bold and Text normal. AND I have to take care to cariage

See Mark's comment. If you can get away with one View. If however each of
those times is clickable, then just set max number of TextViews in each
list element, as simply removing unused ones by calling
setVisibility(INVISIBLE) on each one.

Ok I will try that thanks !

But I think the problem is somewhere else  because, I comment all the code 
of my adapter in order to return static string for fix number of child and 
group items and I still have lots of GC So the problem maybe doesn't 
comes finally from my CustomView

I will look deeper into that direction and after, i will look at your 
advice with SpannableStringBuilder

[android-developers] Getting action bar height while minSdkVersion is 7

I am faced with an issue - I need to know the action bar height when our 
app is running on Android 3/4.

However, ActionBar class might not exists as our minSdkVersion is 7, and it 
seems that the height is not standard. I tested on 2 tablets and they are 
both 56 - but on users reported that on Galaxy S2 our assumption is wrong!

What's the best way to get the action bar height in program when detected 
that we are running on Android 3/4? Thanks!

[android-developers] Application Restarts Suddenly While trying to decode using speex ?

2012-07-03 Thread amit



*What my App does ?* The App I am developing is a typical client server App 
which talks to a windows server using Wifi. The Application has multiple 
Activities and really has heavy memory and CPU requirements i.e native 
calls for speex encoding / decoding.

*What my Problem is ?* The problem is the Application restarts suddenly 
while working absolutely fine. Sometimes while working normally suddenly I 
see (in logcat ) that the Constructor of Application class (Class which 
extends API's Application Class) is called. That crashes my App since all 
the global data is stored with in the Application class itself.

*What I have done ?* The first thing which struck my mind was that may be 
Android feels their is low memory so it terminates my App, and than 
restarts it automatically. So I implemented onLowMemory()of Application 
class. But to my surprise it is never called..

*What is the main problem ?* The main problem is that Nothing is printed on 
LogCat. It looks that even the Android itself is clueless about why it 
restarted my already running Application ?

What could be the possible reason of this sudden restart ? How can I avoid 
that ?

No there is no such method, even if you try System.exit().. the App might 
be still active in background.. That is the normal behavior for the Android

[android-developers] Re: Getting action bar height while minSdkVersion is 7

The action bar can also change size with custom (OEM) themes.  So I would 
take a different approach and find the size of the usable window left to 
your application.  This is just a case of calling getWidth and getHeight on 
the root object of your view hierarchy.

Hi,

[android-developers] Re: java.lang.IllegalArgumentException: contentIntent required

It seems there is no answer here or on Stackoverflow for this behaviour, so 
I have to assume it's a notification from a service bug for a small number 
of Android devices.  Where do I report this as a bug? 


On Saturday, June 30, 2012 9:19:18 PM UTC+1, brandall wrote:

 The full error also contains:

 android.app.RemoteServiceException: Bad notification for startForeground:

 I've read other similar posts 
 herehttp://stackoverflow.com/questions/3112008/android-java-lang-illegalargumentexception-contentintent-required-error-cause,
  
 tried their suggestions and read their links, but a small number of users 
 are still reporting this error.

 *Overview*

 An activity is started by an external application. This activity starts a 
 custom speech recognition service. It *does not* use startForeground:

 this.startService(intent);

 The activity then calls finish();

 The service starts the custom speech recognition class and passes context 
 to it in a constructor. On 'beginning of speech detected' I display the 
 following notification:

 String notTitle = Hello;
 String notificationText = hello there;

 notificationManager = 
 (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
 myNotification = new Notification(
 android.R.drawable.ic_btn_speak_now, notTitle,
 System.currentTimeMillis());
 myNotification.flags |= Notification.FLAG_AUTO_CANCEL;

 Intent intent = new Intent();
 intent.setAction(com.android.settings.TTS_SETTINGS);
 intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
 PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, 
 intent, 0);
 myNotification.contentIntent = pendingIntent;

 myNotification.setLatestEventInfo(mContext, notTitle,
 notificationText, pendingIntent);

 notificationManager.notify(MY_NOTIFICATION_ID, myNotification);

 The notification has no requirement to do anything 'onClick' as it's 
 cancelled as soon as the user stops talking. I was originally passing a 'null 
 intent', however, after reading many posts, I added in the random 
 intent/pendingIntent of displaying TTS Settings, just to rule this out as the 
 problem.

 99% of my users don't have an issue with either the above code or passing a 
 null intent. I need to solve this for the 1% though, as it's a very important 
 part of my application.

 Any suggestions would be very much appreciated.

I've replied directly to the email, as well as requested support from the

address from filling out the support request.

For now I'd like to keep the name of the app private as I would rather work 
with Google to remedy this issue rather than posting all the details in a 
public forum where a blog/news site can make a story out of it.

I'm afraid you misunderstand - if you are trying to find out the
action bar height just to subtract it from the screen height and see
how much space is left for your app to draw into, you can get that
directly by calling getWidth()  getHeight() on your root View.  Or
alternatively, if you're using GL with GLSurfaceView, you get the same
information as parameters of your Renderer's onSurfaceChanged().

Either way, you don't have to care what the action bar's geometry is,
or if there even is an action bar at all.  My minSdkVersion is 7, too,
so trust me, this works. :-)

com.android.settings.TTS_SETTINGS is not part of the Android SDK,
near as I can tell, so you should not be using it in the first place.
Moreover, few of the settings activities are guaranteed on any device
anyway, which is why you see the sentence In some cases, a matching
Activity may not exist, so ensure you safeguard against this for many
of the settings actions that *are* in the SDK. It is fairly safe to
assume that not all devices will offer an activity for this
undocumented and unsupported action.

So, first, create a test case that is:

1. Reproducible (otherwise, there's little anyone can do), and
2. Does not use things that you should not be using, like
TTS_SETTINGS, that may cause your test case to be ignored

Then, and only then, file an issue on http://b.android.com.

[android-developers] Android 4.1 Jelly Bean GIF Images Not Showing?

2012-07-03 Thread Josh F.

I'm wondering if it is just me or not, but I have a game that has been 
out for years now that uses GIF files for some of the bigger images (many 
are PNG, but some are GIF).  In the latest Android 4.1 Jelly Bean release, 
the emulator continues to show these images without any problems in every 
configuration I have tried, but the devices that are running 4.1 right now 
(the Nexus 7 and Galaxy Nexus) both fail to show these images in the game. 
 There is no crash and no other failure and the game behaves as if the 
images are present (some you can select/touch/etc. and it works).

As I don't yet have a 4.1 device (unable to get tickets to Google I/O which 
is the only way to have a legitimate one right now) and I do not want to 
flash a hacked ROM on my own Galaxy Nexus test devices (we keep them stock 
for testing) I was hoping someone else in the community has seen this and 
has a recommendation.  Otherwise, it looks like I'll be doing a lot of GIF 
to PNG conversions for the next few days...

[android-developers] Java.Text.DateFormat returns wrong pattern for en-GB in Android 4.0.x

2012-07-03 Thread Edward Lin

Please help me with this date time localization issue. I am trying to use
Java.Text.DateFormat to get the default date format for different locale in
the following.

dateFormatter = DateFormat.getDateInstance(DateFormat.SHORT, Locale.UK);
String formattedDateString = dateFormatter.format(new
Date(System.currentTimeMillis()));

When I am trying to format the date using en-GB locale for the date - July,
3rd, 2012

Android 2.2.x.-2.3.x result: 03/07/2012  (Correct)
Android 4.0.x result: 07/03/2012  (Wrong)

Apparently, It is working at Android platform 2.2.x to 2.3.x, but in
devices with 4.0.x (such as ASUS Eee Pad and Samsung Nexus 2), it does not
work anymore. Why is this behavior different between the API level? And how
can I get the default date format for specific locale from now on?

Thanks,

Edward

[android-developers] Re: Java.Text.DateFormat returns wrong pattern for en-GB in Android 4.0.x

From:
http://developer.android.com/reference/java/util/Locale.html 

*Note that locale data is not necessarily available for any of the locales 
pre-defined as constants in this class except for en_US, which is the only 
locale Java guarantees is always available.*

*It is also a mistake to assume that all devices have the same locales 
available. A device sold in the US will almost certainly support en_US and 
es_US, but not necessarily any locales with the same language but different 
countries (such as en_GB or es_ES), nor any locales for other languages 
(such as de_DE). The opposite may well be true for a device sold in Europe.
*
It might be that the devices you are testing on does not support the 
Locale.  Can you enumerate the installed Locales or test to see if the 
Locale you want is installed?

Point taken thanks - I should have clarified that I'd tried a null activity 
as well as an activity to open my application and eventually the TTS 
Settings. In all cases successful for 99% of my users. The remaining 1%, no 
joy...

Thanks for the link.

Re: [android-developers] big bluetooth packets

It has never happened with my Galaxy Tab.

[android-developers] TransactionTooLargeException exception calling queryIntentActivities()

2012-07-03 Thread Bryan Ashby

Part of my applications duties are to enumerate launcher activities -- to 
do this, I call PackageManger.queryIntentActivities(). On some devices this 
has resulted in a *TransactionTooLargeException*. Is there a way around 
this? 

*Example code:*

 final PackageManager pm = getPackageManager();
 Intent intent = new Intent(Intent.ACTION_MAIN, null);
 intent.addCategory(Intent.CATEGORY_LAUNCHER);
 final ListResolveInfo ri = pm.queryIntentActivities(intent, 0); 
 // TransactionTooLargeException


I saw a related post about 
getInstalledPackages()https://groups.google.com/forum/?fromgroups#!topic/android-developers/EK4eJPadabsbut
 it seemed to end with Don't do that which seems like an odd answer to 
just using the API. I'd expect that in this case if the underlying 
implementation is limited to 1M that the query is done in batches and 
hidden from the developer or that an API exists to do it in batches myself.

Any ideas? This works nearly all of the time (expected!) but it seems that 
every now and then I'm running into this exception in the wild on customer 
devices.

Hi Zohob,

Thanks for your response. I am able to vibrate the device. What I am

setting reminders in calendars. Just in place of reminder I want the device
to switch to Vibrate mode and once that time is over should come back to
normal.

Hope this clarifies my requirement. Let me know if otherwise.

Is that in your null Intent case? The message makes more sense for

It looks like contentIntent used to be required, but no longer is, as

I would recommend using an Intent that points to one of your

Re: [android-developers] Re: How to: Free to Paid App and retain preference and db files?

Hi,

Well, your point of view is not statistically relevant, but as android
developer what I want -and I think this is actually generalizable- is
the most income for my work.

And my limitated experience with just one app after two months of its
release in both forms, free with ads and payed without them, is that I
have got more than 35 times more income from the ads on the free version
than from purchased one.

I do not want to reveal the exactly income, but you can get the idea
from these numbers: for 10 dollars of income on payment version, I have
got 350 dollars from ads on the free one.

And for me it is pretty clear that after more than 100.000 installs on
the free version and less than 100 on the payed one, is that there is A
LOT of users out there that does not care a bit about the ads. And such
quantity of users are statistically relevant, indeed.

Though my app is a casual game and I am pretty sure that in other type
of apps things may work in a different way. For example, on a scientific
calculator ads will be really annoying and users of that kind of app are
not likely to click on the ads as casual game users does.

Best regars,

 Yes, I have additional features for the paid version but was thinking to
 maintain the Ads in the free version.
 So you are suggestion to completely remove the Ads for free and focus on
 the Paid version for incentive?

 My suggestion, as a fellow developer, is to give it some thought, rather
 than assuming that ads are some kind of Eleventh Commandment.

 In-app billing, or a separate unlocker app, seems like an easier
 free-to-premium migration path than two separate apps. So, losing some on
 the ads, you might gain some in the upsell conversion ratio.

 As an Android *user*, though, I really dislike apps with ads.

 The idea of irritate the user until he agrees to pay just seems wrong to
 me.

Well, I'd at least consider adding MATCH_DEFAULT_ONLY on the

Beyond that, I'm not sure if by default you get everything in the GET_

expressly listing the GET_ flags you really need might help.

Basically, TransactionTooLargeException means you're trying to

JAVA_HOME should be set to the JKD dir not the JRE dir, such that both:

will work

on my machine for example 
JAVA_HOME=C:\apps\Java\jdk1.6.0_32

If you still get problems then try this:
when you get to the page in the installer where it tells you it can't 
find Java
click [back]
click [next]
this sometimes clears the problem

It's definitely replicated when using the main activity to launch the

W/19:27:15.560 ActivityManager( 220)
Error showing notification for service

I haven't narrowed down which OS/Devices are having the problems - I will
do though. A dev on StackOverflow commented on the linked post that he only
found this issue on the Kindle Fire. I have LG devices reporting this
though..

Can't help thinking that there's a glitch in the matrix on some devices
where startforeground is 'expected' when firing a notification from a
service...

Thanks again for your replies. I'll continue to investigate.

 In my opinion, it is far better to let users opt out of ads for free than 
 use advertising as some sort of black mail to push users into paying. In 
 our app, only 2.7% of users choose to opt out of banners. 
This is pretty interesting, but I think if you put the ads disabled by
default and puts an option to enable them, you will get the inverted
proportion... I know it is an elucidation, but my hypothesis is that
those numbers could be explain also for the laziness of the majority of
the users, not only for their interest on banners.
 The rest let them 
 display. We have premium users who choose not to opt out as well.
 A small percentage of users hate ads. Giving them the opportunity to just 
 remove them easily and freely increases the acceptance of your app and also 
 helps give it a positive image.
Now put that theory on measurable income numbers...
 One thing to keep in mind. By not allowing free opt out, all you are doing 
 is decreasing the CTR for your ads and that lowers revenue. 
:potatoes

That's not true, indeed. You get income for each click, whatever the CTR
is. Please, bear in mind that the CTR is the resulting proportion of
dividing clicks by impressions, not the other way. In other words: if
your clicks worths one cent each one, with 1000 clicks you will get 10
dollars, and it does not matter if the CTR, that may vary with the
number of impressions, is 1% or 2%.

Moreover, from my own experience with Admob I am pretty sure that they
penalize high CTR rates, considering more clicks non valid with high
CTRs than with lower ones.
 Part of secret 
 sauce for determining what you are paid is the CTR, so keeping that high 
 will increase your revenue.

 Apparently, It is working at Android platform 2.2.x to 2.3.x, but in
 devices with 4.0.x (such as ASUS Eee Pad and Samsung Nexus 2), it does not
 work anymore. Why is this behavior different between the API level? And how
 can I get the default date format for specific locale from now on?

[android-developers] Abnormal behavior of media scanner when I renamed a folder which have some media files.

2012-07-03 Thread Hyuck

Hi All,

I have develop a kind of file manager app. recently, I have met a strange 
behavior of media scanner.
There was a folder(A) with some media files in it. and I renamed the folder 
name to B. 
However, after a re-scanning , there is still folder A, and the folder have 
media files which have 0bytes.  
is there anyone who have this kind of problem? if so, please give me some 
advise. it would be much appreciated.

Hyuck.

No, I was referring to the error message. While it *says* Bad
notification for startForeground, it appears that this error might be
raised even if *nobody* called startForeground(). Hence, I am telling
you to not over-emphasize the Bad notification for startForeground
portion of the error, as it may be a red herring, fluke, or something
else fishy.

IMHO, the real question is: where is your contentIntent going?
Somehow, Android is winding up with a Notification object that has a
null contentIntent, and that appears to be unsupported, at least on
Android 1.x/2.x. In the cases where you are explicitly supplying a
contentIntent, it should no longer be null. Are you doing anything to
the Notification object after you call notify()?

 No, nothing... The notification says I'm listening and then is cancelled 
a few moments later 'on end of speech input'  from the service. First time 
I got the error using null contentIntent, I thought, okay, I'll just add in 
the content to suppress the error, but my headaches started when it appears 
to make no difference either-way or regardless of the actual contentIntent 
supplied...

Is it possible that you are canceling it before it actually gets

I'm just brainstorming possible things that you are doing differently
than the norm.

Re: [android-developers] GridView with images aligned bottom in a RelativeLayout

So, here is what I think is going on...  ImageView is basically a container
for your actual image.  The scaleType indicates how the image should be
scaled to fit inside the ImageView.  The alignParentBottom affects the
container, not the image.  That is why you are getting the results in your
attached image.

If you set the scaleType to fitXY I would guess that you wouldn't see the
blue anymore and all the images would be the same size.  Note that this is
not what you want to do, because that settings scales X and Y
independently, which will cause your images to get stretched and look funny.

You could try fitEnd, but I don't know if that will get you exactly what
you want:
http://developer.android.com/reference/android/graphics/Matrix.ScaleToFit.html#END

Ultimately, you might have to come up with your own scale matrix...

 I've searched this forum up and down and found different solutions but
 none of them have worked as expected. I even tried looking at the Shelves
 project that's open sourced and that seemed much too involved for what I'm
 trying to achieve here.

 I have a screen with a bookcase/bookshelf background and have it scrolling
 as desired with the code below. My RelativeLayout height does not seem to
 be honored and changing it from 100dp to 200dp makes no difference. I
 basically need each row in the GridView to be the exact same height and
 vertically align the thumbnail image bottom so that the image sites on the
 bookshelf. I sort of achieved this by hardcoding the layout width/height
 for the ImageView itself. I've tried using a background color so that I can
 see what's going on but I still fail to achieve a consistent look. I'm also
 trying to scale the images down to a consistent size, let's say 100x100
 even though the images will be different shapes (some are squares and some
 are rectangles). I also can't seem to get the image to bottom align in the
 RelativeLayout which builds the cell even though I'm using the
 android:layout_alignParentBottom=true attribute.

The notification is there for at least as long as I set the 'pause before 
assume speech has ended' parameter to. The endOfSpeech can't be called 
until after that event (where the notification is cancelled), so we can 
rule that one out. I'll push out the NotificationCompat.Builder update 
later, but even if (hopefully) it solves the issue, perhaps I should still 
do the honourable thing and raise it as a possible bug? Or in your 
experience, are depreciated method bugs pushed to the bottom of a very 
large pile and therefore pointless...? 

I appreciate your help.

[android-developers] Re: HELP! Google removed my app with millions of users!

2012-07-03 Thread FiltrSoft

Wow, where exactly do you have your ads?  I have ads at the very bottom of 
my app, wonder if Google would consider that placement that would cause 
users to accidentally click on them, since they are near the phone's 
hardware buttons?

They really need to be more specific when they ban apps, because there's so 
much room for interpretation.  On top of that, it's extremely difficult to 
contact anyone at Google.

Sometimes I feel I should only develop web-based mobile apps.  Too much Big 
Brother with native apps.

 Without warning, a few days ago my long standing successful app was 
 removed from the play store. The app has been around for over 2 years now 
 and has around 1.5 million active users, and nearly 5 million downloads. 
 It's been in the top 5 of its category for well over a year. It has over 
 65,000 ratings with an average of 4.6/5.

 The email I received said that the app was removed because Google says 
 *Violation 
 of one or more of the following provisions of the Content Policy: 
 spamhttp://www.android.com/us/developer-content-policy.html#spam
 , intellectual 
 propertyhttp://www.android.com/us/developer-content-policy.html#IP, 
 and impersonation or deceptive 
 behaviorhttp://www.android.com/us/developer-content-policy.html#impersonation
 * and more specifically because *core features of your application 
 causes users to accidentally click on advertisements*

 First of all, the ads are hardly accidentally clicked... The highest 
 average click rate I've ever gotten was 0.8%. Even still I've read over the 
 Content 
 Policy http://www.android.com/us/developer-content-policy.html as well 
 as the Distribution 
 Agreementhttp://www.android.com/us/developer-distribution-agreement.html 
 and 
 neither call out specific ad placement rules, guidelines, or suggestions. 
 The ad placements are also similar to hundreds of other most popular apps...

 I'm more than happy to upload a compliant version of the application 
 putting the advertisements in whatever position is deemed acceptable by 
 Google. I'm not unethical or a con-artist, I'm a recent college grad from a 
 smaller town after all... Re-releasing the application under another 
 package name would be unfair to the 1.5 million active users out there as 
 they wouldn't get the update notification or keep their settings.

Re: [android-developers] Re: NotificationManager, get methods

 Why there is no read methods in NotificationManager?

Because an app can keep track of its own notifications, and an app
should not have access to other apps' notifications.

 Is it on purpose?

Most likely.

 Will it be added in future releases?

You will find out when the rest of us find out, when future releases
are released.

 If not, maybe somebody know how to get Intent object out of PendingIntent?

There is no API for that, sorry.

Re: [android-developers] Re: java.lang.IllegalArgumentException: contentIntent required



 Well, I don't see any deprecated methods in what you are doing. 
 However, bugs that cannot be reproduced tend to be problematic in all 
 software development. 

 I'd assumed that the posted method had been depreciated in favour of 
NotificationBuilder. I see that it hasn't though. 

I'll get the list of device/OS combination where this occurs and go from 
there. 

Thanks again for your input

[android-developers] Dynamically switching text-to-speech engines under ICS?

2012-07-03 Thread blindfold

Has anyone had any success reliably switching among text-to-speech engines 
and languages on-the-fly under Android 4.03 (ICS)? Under Android 2.3.3 this 
worked great using the TextToSpeech method setEngineByPackageName(), but 
that method is now not only deprecated but for some reason it no longer 
reliably switches among installed speech engines. I use the Google 
Text-to-speech Engine that comes with ICS, the SVOX Classic TTS and eSpeak 
TTS on an HTC Desire ONE X running Android 4.03. 

I had no problems quickly and reliably switching among installed TTS 
engines and their languages on an old HTC Desire running Android 2.3.3. 
Whatever I try now under Android 4.03, results are erratic at best. The 
deprecated setEngineByPackageName() sometimes works and sometimes it 
doesn't - and I really do not mind not knowing when it finishes switching 
engines. Doing stop() and shutdown() on an active TextToSpeech instance 
before creating a new one for another engine via TextToSpeech(context, 
listener, engine) and then waiting for its listener to be invoked before 
testing with isLanguageAvailable() if a certain language is supported by 
that engine also proves unreliable. As far as I am concerned, Android 4.0 
appears a major step backwards as compared to Android 2.3.3 where it comes 
to dynamically switching TTS engines and languages, and after spending many 
hours I still have not found a reliable workaround that lets me 
programmatically switch between languages among multiple installed TTS 
engines that each support different subsets of languages. It should not 
have been hard to switch between, say, SVOX Classic TTS for Dutch and the 
Google TTS for German? Or are the third-party TTS engines to blame for 
still flawed ICS support?

Thanks!

Google does not certify your application. You are thinking of Apple,
or perhaps Amazon, who manually review each application. Google does
not.

[android-developers] Re: activity looses ArrayList items

I don't think Vector is thread safe in the way you expect did you read:

*This class is equivalent to 
ArrayListhttp://developer.android.com/reference/java/util/ArrayList.html with 
synchronized operations. This has a performance cost, and the 
synchronization is not necessarily meaningful to your application: 
synchronizing each call to get, for example, is not equivalent to 
synchronizing on the list and iterating over it (which is probably what you 
intended). If you do need very highly concurrent access, you should also 
consider 
CopyOnWriteArrayListhttp://developer.android.com/reference/java/util/concurrent/CopyOnWriteArrayList.html
. 
*
http://developer.android.com/reference/java/util/Vector.html 

The implication of the above is that your Vector change be changed from 
another thread whilst you are trying to serialize it.

[android-developers] process.destroy() logging exceptions in ICS

2012-07-03 Thread elliotn

When I try to destroy the (short running) process in ICS the System logs 
the below exception. I'm very puzzled as the code runs fine on Honeycomb. 
Anybody else seeing this?

I/System  ( 2369): Failed to destroy process 2412
I/System  ( 2369): libcore.io.ErrnoException: kill failed: ESRCH (No such 
process)
I/System  ( 2369):  at libcore.io.Posix.kill(Native Method)
I/System  ( 2369):  at 
libcore.io.ForwardingOs.kill(ForwardingOs.java:77)
I/System  ( 2369):  at 
java.lang.ProcessManager$ProcessImpl.destroy(ProcessManager.java:257)


Here's what the code looks like:

Process process = null;

try {

  process = new ProcessBuilder().command(/system/bin/somecommand)
   .redirectErrorStream(true).start();

  ...

} catch (IOException e) {

// handle exception

} finally {
  if (process != null) {
 process.destroy();
  }
}


Thanks!

 I'm afraid you misunderstand - if you are trying to find out the 
 action bar height just to subtract it from the screen height and see 
 how much space is left for your app to draw into, you can get that 
 directly by calling getWidth()  getHeight() on your root View.  Or 
 alternatively, if you're using GL with GLSurfaceView, you get the same 
 information as parameters of your Renderer's onSurfaceChanged(). 

 Either way, you don't have to care what the action bar's geometry is, 
 or if there even is an action bar at all.  My minSdkVersion is 7, too, 
 so trust me, this works. :-)

Re: [android-developers] Re: Getting action bar height while minSdkVersion is 7

No it does not - at least this is the result of my test.

I got an ICS and a Honeycomb devices - the getY() values are exactly 56 
pixels too low when the same app run on them. I have to subtract 56 from 
the getY() to get the correct position. Same code works fine on 2.x and 1.x 
device.

I am the author of some popular kids painting softwares, and this has been 
the issue I faced for quite some times.

Yes. Use the new TextToSpeach constructor that takes an engine package name.
Create a new instance when switching engines.

[android-developers] Ping in android

2012-07-03 Thread Michael Leung

Hi all,
  I have  used  isReachable()   in InetAddress for Ping. But that is only
working in local network unless root my phone.
Does anyone work this problem out before?

Re: [android-developers] Re: Getting action bar height while minSdkVersion is 7

2012-07-03 Thread Dianne Hackborn

What you are claiming is happening is...  well, you probably need to
explain more.

If you have an action bar, then by default your content is placed below it,
and the coordinate space of events received by the view will be relative to
where it is placed.  This is true with all views in the hierarchy.  If it
wasn't, all of your presses on UI elements in a window that has an action
bar would be off.

I can't understand how you are doing things such that you have to subtract
an offset.  Your content is below the action bar...  that's where it is,
there is no offset to subtract.

If you *want* your content to go behind the action bar, you can request the
feature that the action bar be shown as an overlay on top of it:
http://developer.android.com/reference/android/view/Window.html#FEATURE_ACTION_BAR_OVERLAY

Using this does mean that the top of your content will be covered by the
action bar when the action bar is not hidden.

 No it does not - at least this is the result of my test.

 I got an ICS and a Honeycomb devices - the getY() values are exactly 56
 pixels too low when the same app run on them. I have to subtract 56 from
 the getY() to get the correct position. Same code works fine on 2.x and 1.x
 device.

 I am the author of some popular kids painting softwares, and this has been
 the issue I faced for quite some times.

 Really? I would expect that the MotionEvent getY() would be with
 respect to your View that is receiving the touch event.

Re: [android-developers] Re: Getting action bar height while minSdkVersion is 7


OK, this is part of my code, very simple:

public boolean onTouchEvent(MotionEvent event) {

int count = event.getPointerCount();

...

 

int action = event.getAction();

int x = (int) event.getX();

int y = (int) event.getY() - absize;

...



return true;

}


The absize is the current Action Bar height I am using. If without it, 
event.getY() will works fine in Android 1/2 devices, but on my HTC 
Jetstream (Honeycomb) and Galaxy Note, the Y value is offset by 56 pixels 
(which is my current absize). In both cases, I tested them with finger and 
stylus.


Ideally it should be like what you say, event.getY() just works, but it 
does not. My minimum SDK level is 7 as I intend to support older devices 
but allows for Action Bar on Android 3/4 devices. I think this might be the 
issue (ie, getY() will works fine if my minimum Android version supports 
Action Bar by default).

Re: [android-developers] Abnormal behavior of media scanner when I renamed a folder which have some media files.

2012-07-03 Thread Hyuck

Thank you for your interest. 

after I renamed a folder. I did re-scanning by sending broadcast intent as 
below. 

 Context applicationContext = MyApplication.*getInstance*
().getApplicationContext();

 applicationContext.sendBroadcast(*new* Intent(Intent.*
ACTION_MEDIA_SCANNER_SCAN_FILE*, 

and then, delete former folder name in database as below. 

*public* *boolean* deleteFolder(String folderPath){

 

 *boolean* isSuccessful = *false*;

 Cursor cursor = *null*;

 String selection;

 

 DELETE_FOLDER : {

//1. Get folder '_id' list.(with duplicated one).

ArrayListInteger folderIdList = *new*ArrayListInteger();



   String[] projection = {

FileSchema.Columns.*_ID*

   };

selection = FileSchema.Columns.*DATA* +  = \ + 
folderPath + \;

cursor = SqliteWrapper.*query*(getContext(), 
getContentResolver(), FileSchema.*getContentUri*(external), projection, 
selection, *null*, *null*);

*if*(cursor != *null*  cursor.moveToFirst()  
cursor.getCount()  0){

  *int* dataIndex = cursor.getColumnIndex(FileSchema.Columns.*
_ID*);

   *do* {

   folderIdList.add(cursor.getInt(dataIndex));

   } *while* ( cursor.moveToNext() );

   cursor.close();

} *else* {

   isSuccessful = *false*;

   *break* DELETE_FOLDER;

}



//2. Delete folders in DB.

*while* ( folderIdList.isEmpty() == *false* ) {

   *int* folderId = folderIdList.remove(0);

 *int* numberOfDeleted = 
SqliteWrapper.*delete*(getContext(), 
getContentResolver(), FileSchema.*getContentUri*(external), _id=\
+Integer.*toString*(folderId)+\, *null*);

 *if* (numberOfDeleted  0) {

isSuccessful = *false*;

*break* DELETE_FOLDER;

 }

  }

//3. Delete files in DB.   

selection = FileSchema.Columns.*DATA* +  LIKE \ + 
folderPath + /%\;

*int* numberOfDeleted = 
SqliteWrapper.*delete*(getContext(), 
getContentResolver(), FileSchema.*getContentUri*(external), selection, *
null*);

*if*(numberOfDeleted  0){

   isSuccessful = *false*;

   *break* DELETE_FOLDER;

}



//4. Success!

isSuccessful = *true*;

*break* DELETE_FOLDER;

 }

 

 *return* isSuccessful;

}

I don't know about after 10 secs (not sure where you got that number, but
yes, once the Thread is done executing, the system takes care of it. I'm
not even sure how you would kill it manually.

Besides that, the use of your thread in your snippet is quite useless. Your
two lines of code don't need to run in a separate thread.
