[android-developers] update screen frequently

[pramod.deore]

Hi all, In my application I have list of multiple rows and columns.
The values of these rows and columns are coming from server and these
values are changes frequently. (near about after every second) Now I
want to show updated values each time without refreshing or pressing
back button. How to achieve this? Thanks in advance.

[android-developers] Re: "Live Wallpaper", "Menu button" etc in different languages

[Zsolt Vasvari]

In particular "Live Wallpaper" is, in all likelihood, a trademarked
marketing term.

I would try find a Chinese language website that lists the features of
Android 2.1 and see what terminology is used by Google.

Re: [android-developers] Re: Timezone Question

[Bob Kerns]

Ah. I'd guess, from what you're telling me, that the user's phone has the
wrong time, the wrong local time zone, and the correct local time display.
I'm not sure how we'd figure that out for sure

Anyway, your idea of an override preference is probably the best thing you
could do in your software (if it's worth it).

But might it be better to tell the user that he can set the timezone to use
in Google Calendar's web interface?

Google Calendar stores actual times (rather than formatted times). If you
set the time to use in the web interface, you can even set an event to start
in one time zone and end in another!

Of course, it's possible he's using some broken third-party software to
access his Google Calendar -- but if he's using the standard app, or he uses
the web interface correctly, it should work properly, and he shouldn't need
to lie to his phone.

I had an idea of using a statistical approach by parsing through all strings

[android-developers] Wifi lock with WIFI_MODE_SCAN_ONLY

[seema]

Hello All,

   Here is what I do to scan on wifi while connected to 3G.

WifiLock wifiLock =
wifiService.createWifiLock(WifiManager.WIFI_MODE_SCAN_ONLY,
"MyLock");

if(!wifiLock.isHeld()){
wifiLock.acquire();
}

if(wifiService.isWifiEnabled() == false){
 wifiService.setWifiEnabled(true);
 }

Is my usage of WIFI_MODE_SCAN_ONLY is correct. It did not work for me.
When I enable Wifi, it automatically connects to the remembered
network. I just want to scan but not connect.

Regards,
Seema

[android-developers] CheckedTextView and filtering of list not working well together

[Lowell Kirsh]

I have a list of checkable items and an EditText which I use to filter this 
list of items. If I check, say, the second item in the list and then filter 
the list by entering some text in the EditText, it will keep the second list 
item checked even though, after filtering, that might be a different item 
than was originally checked. What pattern should I use to be associating the 
checked state with the backing object rather than its index within the list?

Thanks
Lowell

[android-developers] Market sales suddenly cut in half

[Brill Pappin]

All of a sudden on April 20th, our daily payout dropped to half the
normal sales/day.
It has been consistently half ever since across all of our apps.

Has anyone else notice that kind of drop in the last four days or so?

[android-developers] Fragmentation-resistant product design

[Vikram]

Guys

We have noticed that while all the phones (that we have seen) store
photo timestamps in the Local timezones in which they were clicked,
the Motorola Droid Pro store EXIF photo timestamps in GMT. The photo
viewer shows it in the timezone of the viewer (Confirmed by
https://supportforums.motorola.com/thread/39204).

Any advice on how to handle this issue more from a design perspective?
As we keep identifying more issues of this sort, we are adding
abstractions at different points where our code interacts with the
system. Is this the way to go? Also, any advice on how to identify a
device? We are planning to use make and model keywords like
Make=Motorola, Model=DROID PRO, Product=venus2_vzw, Device="verizon/
venus2_vzw/cdma_venus2/venus2:2.2.1/3.4.2_80_V2_87/8:user/release-
keys"

By the way, I just read your "open letter".

[android-developers] Re: How do you counter repeated bogus reviews from competitors?

[Brill Pappin]

This has happened to us several time.
We never find any *proof* of which competitor is doing it (except if
they push users to another app), but the pattern makes it obvious
that  your being targeted.

Some of what we've seen:
- Blatant lies about the features.
- Claims "stealing" from the users.
- Claims of problems and no support (we run a very tight support and
test it daily).
- Simple ones like "it sucks".

Almost every time you get multiple 1 or 2 star ratings in a row and/or
multiple different users with similar bad reviews in a row.

It makes me pretty pissed, but we haven't found a good way to counter
it because you don't have any data you can send to Google in order to
get them to do anything about it.
So far the only thing that I've found effective at all is to reply to
the user politely and with a positive action comment (of course your
comment has 5 stars for your own app).

We find that the best way in the end is to actually attempt to provide
a good product. Implement good support and respond to your users. Fix
problems as soon as possible.

For us, the apps don't bring in enough to make it a full time job, so
we have to dedicate ourselves to the most pressing issue when they
crop up.
Even a really bad bug that slips through can be alleviated by good
support and by actually trying to fix it.

What ever you do, remember that some users really don't like your app.
Sometimes they are eloquent and sometimes they are not. In those cases
you can try and address their issues, but you won't make everyone
happy and its important not to deride your user legitimate users who
have a problem.

One other thing. When your app really has a problem, I find its better
to for you to accept it and let your users know you had a problem but
are (or already have) fixed it. They are more likely to trust your
word then.

[android-developers] Samsung Galaxy S calendar app on Sprint allows starting "Google Maps" or "Sprint Navigation" only to "Complete action using" when clicking on Location.

[Michael Franz]

Hi all,

Samsung Galaxy S calendar app on Sprint allows starting "Google Maps" or
"Sprint Navigation" only to "Complete action using" when clicking on
Location. This is a pretty serious limitation, which does not
allow implementing proper Location processing - for example to dial
conference bridge, typically found in this field.

Note that "normally" this can be done by using the following intent-filter:



 




Any ideas on how to overcome this limitation (while still using the built in
calendar app) will be appreciated.

Thanks,
M.

You can use 'adb remount' to remount /system ready-write.
However, on the emulator it shows up with 0 free space,
so I don't think you can make any changes. Your best bet
is to use a real rooted device, I think.

Yes, precisely.  Double-tap long-press in my lingo is down-up-dooown.
Triple is down-up-down-up-dooown.  I used similar actions for a
different app almost a year and a half ago (WildSpectra) but they
weren't on an EditText, they were just on a custom view, so the
context menu issue never came up before.

Regarding the actual solution, unless I have mistaken what I am
seeing, it does look like my solution works: override
showContextMenu().

Cheers!

[android-developers] Re: How do you counter repeated bogus reviews from competitors?

[Maps.Huge.Info]

Wow. That really sucks. There is very little you can do about it but I
suggest making sure you mark the comment as spam. I believe if enough
people mark a comment as spam, something kicks in and it either gets
reviewed by a human or is just removed. Put that in your blog or
however you communicate with your users so they do the same. It might
not do anything but then again, I think it does.

Another potentially helpful thing you can do is complain to the
company who wrote the competitive app. It may be the comments are the
work of low level employees and the corporate heads are unaware of
their unethical behavior. Write a blog entry describing exactly what
the problem is, why you think it's your competitor and what steps
you've taken to stop it then notify the CEO and president of the
company. Keep it civil and take the high road. Most executives abhor
bad publicity. Bringing your issue to their attention might just stop
it dead.

It sounds like you didn't understand my problem.  The contextual menu
was being triggered on the double and trip tap long presses also.
That was fundamental to my problem.  I couldn't prevent it from
happening under reasonable circumstances.  That was what I needed help
with.

Well, I understand that, but you didn't do both.  You didn't make a
clear philosophical argument and then explain how to achieve the
technical goal of a double-tap long press that does not trigger a
contextual menu.  You stopped half way through.  That was frustrating
from my point of view.

I take your point about the single-tap long press.  I will either
forcibly prevent it from being over-rided in my UI configuration
settings or I will accompany with red flashing alarm-bell associated
warnings that it should only be done if the user is certain they know
what they are doing (I hate telling genuine power users that they
can't do what they want, I love configured UIs to my own nuanced
behaviors, it's the same reason my trackball has gazillions of DOF on
it).  I had already put in a warning message when overriding the long-
press command but you have my thinking that I should make the warning
more aggressive now...or perhaps even lock it out entirely just for
the sake of conformity.  I'll take it under consideration.

Thanks.

That seems reasonable. Your opening line of the thread ("I want to
intercept an EditText long-press and do something with it other than
present a contextual menu") didn't explain that, and I misunderstood
where you were trying to clarify ("I want to provide additional
functionality on double or triple tap long presses,
but it won't work if the contextual menu is forced upon all long presses").

BTW, just so I'm on the right page: a double-tap long-press would be
tap + long-press? And triple-tap long-press is tap + tap + long-press?

And is this a DDR game applied to an EditText? If so, did you license
any cool music? :-)

Regardless, my apologies for misreading that line.

It's more that I've been running into UI-pattern-jacking a lot over on
StackOverflow in recent months, so I'm overly sensitive on the issue.

Not at all. I'm more concerned about *you* being offended, since I'm
the one who misread the key line.

[android-developers] Re: Intercept/override context menu on EditText long-press?

[Keith Wiley]

Just to wrap up this thread for anyone else who finds it and is
looking for relevant information, I was able to achieve the intended
goal by overriding showContextMenu() and either passing the call up to
the super class or dropping the call on the floor.  So when my app
detects a double or triple tap in advance of the call to
showContextMenu(), I simply ignore the call and proceed with the
alternate behavior instead.

...and to wrap up the philosophical argument that this thread
unintentionally flared, I really don't see why double or triple tap
long presses should be expected to exhibit redundant behavior with
that of single tap long presses.  The scenario is perfectly analogous
to single, double, and triple taps (sans long press), or mouse-
clicks.  Clearly, no one expects double taps to exhibit behavior
redundant with single taps.  If that were the case, double tap support
would never have been programmed into the API in the first place (and
let's be honest with ourselves, double-mouse-clicks have been a common
UI for 25 years!).  Triple clicks and triple taps, I concede, are a
bit more contentious in that they are not particularly wide-spread,
but they are not unheard of either and I felt entitled to offer such
support to my app's power users who might benefit from the added
flexibility and ease of use.

Mark, I have always appreciated your input and I'm sorry my original
question offended you.  It was technical, not philosophical, and I am
always weary of attempts to thread-jack an original question because
threads rarely recover and the original question generally goes
unanswered as a consequence.  I would have been more than happy to
politely debate the philosophical and design issues with you, but such
was a tangent from the purely technical question I was asking and I
saw no reason to confuse the two topics; I just wanted an answer to my
question (and perhaps faith that I was not running afoul of wise
design specs even if I had not fully qualified the scenario pertaining
to my question).  I hope you aren't too offended by all of this.

Best of luck.

Cheers!

So?

You have all this stuff for every other touch operation known to
humanity, apparently, yet you can't just leave the long-press alone to
do what an EditText is supposed to do on a long-press? Why not move
your long-press functions to a quadruple tap or something? What is
so magical about you hacking a long-press that is worth
breaking the existing expectations of the users?

You assume that I am here exclusively to help you. I am also here to

> Do you know how to do what I'm trying to do?

The only thing I can think of -- and it's a long shot -- is to call
unregisterForContextMenu() sometime relatively late in the process.
This can also be achieved by calling
setOnCreateContextMenuListener(null) on the EditText itself. I can't
quite see where an EditText/TextView actually declares that it *has* a
context menu. I get the distinct impression from the code I'm reading
that it's somewhat bypassing the normal context menu system. But, in
the off chance you get lucky, if you unregister it sometime after it
has been registered, that might suppress the built-in context menu.

But I really wish you wouldn't.

[android-developers] How do you counter repeated bogus reviews from competitors?

[MB]

Hi,

I am the developer of Android app Gps Ski Maps. We are really
frustrated with competitor writing bogus review about our app(by
buying app multiple times under different accounts and repeatedly
touching the reviews).

 I am wondering how do you deal with this? What steps do you take to
prevent such abuse of Android Market?
We expected some bogus reviews, but not at the scale we saw in Android
Market.
Our app is available on both Android and Blackberry. The spammy review
problems has been really a problem only on Android. Blackberry
reviews( both good and bad:-)) have been mostly genuine as far as I
can tell.
The details of our particular case are written here, but I am more
interested in figuring out the counter steps.

Thanks,

I understand your point, but you aren't being completely fair.  My
Edit text can detect not only single also double and triple taps (I
had to hack triple tap detection from scratch of course).  I want to
provide additional functionality on double or triple tap long presses,
but it won't work if the contextual menu is forced upon all long
presses.  Furthermore my app offers a fully configurable UI where
single/double/triple taps/long-presses/drags can be assigned to
numerous complex functions in a way that greatly empowers the user.

So, with all due respect, we can debate the philosophy how to present
such UIs in a parallel or separate discussion, but it is tangential to
my question of how to technically achieve such powerful goals.

Do you know how to do what I'm trying to do?

Thank you.

Please don't. Users will expect the standard EditText context menu to
appear, so they can do silly things like edit the text. Android
developers get ripped to shreds by users and the media for having zero
UI discipline, breaking existing UI patterns and causing no two apps
to work the same -- your proposal is a case in point.

If your goal is for users to not edit the text, then don't use an EditText.

If your goal is for users to edit the text, leave the context menu
alone, and find some other way to trigger whatever it is that you are
trying to do.

Sorry, quick followup.  The EditText in question is a subclass of my
own creation, not just a generic EditText.  It already extends
EditText and implements TextWatcher, OnKeyListener, OnGestureListener,
and GestureDetector.OnDoubleTapListener for various uses.

Thanks again.

[android-developers] Intercept/override context menu on EditText long-press?

[Keith Wiley]

I want to intercept an EditText long-press and do something with it
other than present a contextual menu.  Obviously, I cannot simply
disable the GestureDetector's long press detection because I do in
fact want to use the long press.  By the time onCreateContextMenu() is
called, it seems to be too late to prevent the contextual menu from
occurring.  Not calling super.onCreateContextMenu for example doesn't
prevent it, nor does anything else I have tried...and
onCreateContextMenu() is called before onLongPress(), so the answer to
my question can't be some behavior in onLongPress().  Should I be
doing something in dispatchTouchEvent(), onDown(), or showPress() to
accomplish this goal?  Those seem to be the only methods that are
called before onCreateContextMenu().

Thanks.

Specifically, the docs state:

"Note that the count [of characters in a pattern] does not specify the
exact width of the field." Just because you have a single "a" does not
mean you get a one-character AM/PM designator.

Actually, no.  :-)

I want to, for example, allow instance #1 to have a different label than
instance #2.  If I continue to use my single Preference Activity which
has one listener for all widgets, it will need to know which widget's
key has been changed so that it can update that instance.  Hm.
Unless I just update all instances all the time when any one instance's

[android-developers] SimpleDateFormat Problem

[Jake Colman]

Per the docs, I should be able to get a time formatted as follows:

  7:33p

with a format string of

  "h:mma"

The result, however is

  7:33PM

Is this a documentation bug, a "Jake" bug, or is this not possible?

I just tried using phonegap as a front for it, however I have exactly the

[android-developers] Re: Integrating Android clients (Native Java and AIR) with Java and .NET backends

[Tim]

I have to agree that integration with back office systems using
various web services can be very difficult.  But in many cases using a
web service to connect to for an example a back office database is a
rather long winded approach, when the Android SDK includes full
database JDBC support.  In fact our rapid application developer tool
MobiForms (see www.mobiforms.com) supports JDBC connectivity to a
range of back office database and is ideal for database orientated
apps.  We have many customers connecting from Android straight back to
ERP and financial packages like SAP, Oracle Apps, Navision and
Dynamics.

Re: [android-developers] Re: Widget-specific Preferences

[Kostya Vasilyev]

24.04.2011 19:35, Jake Colman пишет:

Kostya,

I like your second suggestion.

So in my Preference Activity's onCreate() I should get every preference by
original key name and then reset the key name to include the widget.


Basically, yes.


That means I'll have a full set of non-unique preference keys without
any data but that should not really be an issue.


Not necessarily - if you tweak all the keys inside onCreate, before any 
preference values are saved, I don't think you will have any orphaned value.



According to the docs it does not look like there is a method to iterate
through "all preferences" so, instead, I'll have to get every preference
by specific key name and manually change each one.  Have I missed a more
direct way of changing all the keys?


PreferenceGroup (which PreferenceScreen is a subclass of) has "int 
getPreferenceCount()" / "getPreference(int index)".



If I use an onClickListener() and on SharedPreferenceChangeListener() to
detect specific preference clicks or changes to a preference, I can
parse out the widget ID from the key so that I know which specific
widget has been effected.  I can then make sure that I update just that
specific widget accordingly.  Can you think of a better way to do that?


Umm... Sounds like you also want to present options for multiple widgets 
at the same time within a single preference activity?


If so, I would not use the activity as the event listener.

I'd create a class that encapsulates the complete set of preferences for 
one widget instance, serves as the event listener for the involved 
Preference objects, and knows its associated widget Id value. The 
activity would instantiate these objects as needed, one for each widget Id.


I'd also use onPreferenceChange rather that onSharedPreferenceChanged, 
because the former uses a Preference reference you can switch on, 
without parsing preference keys.


-- Kostya


To facilitate parsing out the widget id, I have already externalized all
my key names as string resources so that I can edit the string to
include a ":".  This way I can parse out the text that follows the ":"
and get the widget id.  Did you do something similar or did you not have
the need to know which widgetid has had its preference changed?


My widgets are so simple, I don't use PreferenceActivity to configure 
them :)

[android-developers] Re: Wallpaper size

[Simon Platten]

I can get the size of the wallpaper from the wallpaper manager:

m_context = app.getApplicationContext();
WallpaperManager wpMngr = WallpaperManager.getInstance(
m_context );
m_intWPheight = wpMngr.getDesiredMinimumHeight();
m_intWPwidth  = wpMngr.getDesiredMinimumWidth();

I can then get the size of the display area:

Display display = app.getWindowManager().getDefaultDisplay();
m_intScrWidth = display.getWidth();
m_intScrHeight = display.getHeight();

I have my image that I want to rescale:

m_bmpImage = BitmapFactory.decodeResource( m_res, intResId );
m_intImgWidth  = m_bmpImage.getWidth();
m_intImgHeight = m_bmpImage.getHeight();

Scaling from the Image height to the display height:

m_fltSFbyHeight = (float)m_intScrHeight / (float)m_intImgHeight;

What I want to do is create a black bitmap that is the same size as the
wallpaper ( intWPwidth, m_intWPheight ), then copy/blit into this bitmap the
bitmap to use as the wallpaper re-scaling it to fit if required, so I end up
with a bitmap image the same size as the wallpaper with the image centered
and scaled in the middle of it.

Thank you.

Re: [android-developers] Connect to emulator with Putty?

[Moose]

If I ever need to edit a file, I use the terminal commands

$ adb pull /path/to/file .
*edit the file as you need to to*
$ adb push file /path/to/file

I know there is also a way you can edit a file by using 'cat' in the android 
shell, but I prefer to edit a dynamic file and replace it.

Re: [android-developers] Re: java

Thought that's what we want - exercise the basics, get used to Java syntax
etc :) The database example is usually done using a custom CSV database file
- to exercise disk operations in Java. Both of these examples are also
easily extendable with more options to  practice the required parts of Java.

[android-developers] Re: Widget-specific Preferences

[Jake Colman]

Kostya,

I like your second suggestion.

So in my Preference Activity's onCreate() I should get every preference by
original key name and then reset the key name to include the widget.
That means I'll have a full set of non-unique preference keys without
any data but that should not really be an issue.

According to the docs it does not look like there is a method to iterate
through "all preferences" so, instead, I'll have to get every preference
by specific key name and manually change each one.  Have I missed a more
direct way of changing all the keys?

If I use an onClickListener() and on SharedPreferenceChangeListener() to
detect specific preference clicks or changes to a preference, I can
parse out the widget ID from the key so that I know which specific
widget has been effected.  I can then make sure that I update just that
specific widget accordingly.  Can you think of a better way to do that?

To facilitate parsing out the widget id, I have already externalized all
my key names as string resources so that I can edit the string to
include a ":".  This way I can parse out the text that follows the ":"
and get the widget id.  Did you do something similar or did you not have
the need to know which widgetid has had its preference changed?

...Jake

It does not go in your project.

Of course.

If you want to read a raw resource, use getResources().openRawResource().

If you want to read an asset, use getResources().getAssets().open().

[android-developers] OpenFileInput

[Dalvin]

Hi

I am trying to read a simple text file in my sample Android Application. I 
am using the below written code for reading the simple text file.

1. InputStream inputStream = openFileInput("test.txt");
2. InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
3. BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

My questions is :
Where should I place this "test.txt" file in my project. I have tried 
putting the file under "res/raw" and "asset" folder but I get the exception 
"FileNotFound" when first live of the code written above gets executed.

Thanks
Dalvinder Singh

and edit my /etc/hosts file for testing.  I was hoping that Putty would 
give me command line access but that doesn't seem to be the case.


Would appreciate any help.

All,

Is there a way to connect to the Android emulator (I am on Windows

Re: [android-developers] Widget-specific Preferences

[Kostya Vasilyev]

Jake,

It's possible to make your subclass of PreferenceActivity use a specific 
preference file by putting something like this inside its onCreate:


PreferenceManager prefManager = getPreferenceManager();
prefManager.setSharedPreferencesName("widget_pref_" + 
String.valueOf(widgetId));


This seems somewhat inefficient though, because each widget will get its 
own preference storage file.


To use a single preference file where each widget gets its own set of 
keys (dependent on a particular widget id), you could try using 
Preference.setKey:


for preference : all Preferences in the screen {
String keyOriginal = preference.getKey();
String keyWithWidgetId = keyOriginal + String.valueOf(widgetId);
preference.setKey(keyWithWidgetId);
}

Hope this helps.

[android-developers] Widget-specific Preferences

[Jake Colman]

I am looking to implemented widget-specific preferences in my app.  I
have reviewed numerous blogs and posts, including Kostya's, and am
familiar with the overall approach of using the widget ID as a suffix to
the preference key.

I currently use a Preference Activity and a preference XML file to
manage my preferences.  Since a Preference Activity handles edits on its
own, is there still a way to use it if I need to change the key name at
runtime to have a widget id?  I am pretty sure I can get the widget from
the intent since it is launched as a configuration activity but can I
tap in and use it?

[android-developers] Re: Timezone Question

[Jake Colman]

Bob, et al,

Wow!  Great comments and replies.  Thanks!

The sunrise/sunset time is given in UTC based on lat/long.  As another
poster said, I do have that part down pat.  My only concern is with how
to display the time for the correct timezone.

My user has manually set his timezone because of a problem with Google
calendar.  He never wants the phone to know that it might have changed
timezones.  The phone still displays the correct time for the local
timezone.  His request is that since the phone knows the correct time,
why is my app not displaying the "correct" time for sunset.

I think I will go with one of the other poster's comments.  Since the
phone is being told its timezone, the app will do what its told.  If it
becomes important, I can always add a preference to allow a user to
override the timezone setting for the app.

Thanks for all the help!

...Jake

Re: [android-developers] how to get the view that is attached to an animation?

There is nothing on Animation for that. You will need to track the
View yourself (e.g., data member).

2. Animation myAnimation = new Animation();
3. myView.startAnimation(myAnimation);   // animation attached to the view
4. View myViewCopy = myAnimation.getAttachedView()

Off the cuff, it feels like a XOOM or Android 3.0 issue.
Unfortunately, we do not have the source code to Android 3.0.

I have no idea how HTML5 geolocation works on the emulator (with DDMS
or telnet as the source of geo fixes). You might try a 2.2 and a 3.0
emulator (note: not 2.3.3 -- buggy) and see what behaviors you see
there. If it works on the 3.0 emulator, then the problem may be
XOOM-specific, and I'd advise you to visit the MOTODEV discussion
boards to provide sample code and explain what you're seeing.

Well, you are way out of my depth, there. I would recommend you head
over to http://source.android.com and join the relevant lists there
([android-porting] comes to mind), provide a *detailed* description of
what you're building and what you're trying to achieve here, and see
what insights you get.

Once you get out of the SDK, this list isn't the right home for the discussion.

[android-developers] Problem installing android sdk in ubuntu 10.10

[Saurav]

Hi all,

I am trying to install android sdk, but the for every try, the android sdk
manager gives this error message:

"Failed to fetch URL
http://dl-ssl.google.com/android/repository/addons_list.xml, reason:
Connection timed out"

It may look silly, but has anybody solved this? And I have tried with and
without https!

Thanks in advance.


Regards,
Saurav Mukherjee.

[android-developers] Building shapes with GL_TRIANGLE_STRIP or GL_TRIANGLE?

[MobileVisuals]

What is the best approach for building 3d shapes, GL_TRIANGLE_STRIP or
GL_TRIANGLE with indices? They say on the opengl.org forum

http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=295940&#Post295940

 that it is better to use GL_TRIANGLE with indices.

Re: [android-developers] How to disable key press events!!

[Pratik Prajapati]

Hi,

Do you mean, I should implement an IOCTL in key board sub-system of linux
that should do report key pressed event to upper layer.
This ioctl can be fired by a native call and my .apk call it with jni
interface?
Does it makes sense? or any better idea?

You're probably making it too easy for your users to accidentally
contact you.  Try making it clear that what they are about to do is
send an email, and give them the option to back out if that's not
really what they want to do.  Just launching an intent to send an
email (through some other installed app or otherwise) might be too
confusing for users who aren't expecting that.

I have a popular app with a feedback option that is buried in a menu,
and only very rarely do I get empty emails.  I also populate the
subject and body text with some info to help the user understand what
they are doing.

[android-developers] Wallpaper size

[Simon Platten]

On Android 1.6 my wallpaper applications resize the wallpapers correctly,
however on Android 2.1 the resizing doesn't work, its the same on the
emulator.

I've tried using both the Matrix and Bitmap.createScaledBitmap both do
exactly the same and work find on 1.6.  Can anyone explain what is happing
and why these routines don't work on Android 2.1?

I start off by getting the device screen size using:

Display display = app.getWindowManager().
getDefaultDisplay();
m_intScrWidth = display.getWidth();
m_intScrHeight = display.getHeight();

I load the image from a resource with:

m_bmpImage = BitmapFactory.decodeResource( m_res, intResId );
m_intImgWidth  = m_bmpImage.getWidth();
m_intImgHeight = m_bmpImage.getHeight();
m_fltSFbyHeight = (float)m_intScrHeight / (float)m_intImgWidth;

Then to scale the image:

m_intFinalWidth  = (int)((float)m_intImgWidth * m_fltSFbyHeight);
m_intFinalHeight = (int)((float)m_intImgHeight * m_fltSFbyHeight);

Thank you,
Simon

You can use any codec you want, if you provide the implementation.

If the hardware/software on both sides of the chat support the same
codecs, then you can use whatever you want.

Each device may be slightly different.  Check its documentation.  Go
here for an understanding of universally supported media types (if
you're using Android APIs for interacting with media):

http://developer.android.com/guide/appendix/media-formats.html

Again, you can always provide your own codecs through some third party
library that operates independently of Android APIs.

[android-developers] No google orders results for SDK11

[Droid]

I have done several apps that target SDK11 alone (Xoom, Acer tablets)
but I get zero downloads results in my orders pages.

I am absolutely certain that there have been downloads but there are
no results (over 5 popular apps).

Have Google switched off downloads and analytics for SDK11?

(Modifying the motion event)

Is the kind of thing that causes apps to break on different platforms or
devices.  It is not at all defined what it means to suddenly modify the
motion event like that.  Just because it happens to do something that you
like doesn't mean it will always do this.
