[android-developers] Re: How to increase FPS (now ~20, desired ~40-50)

2010-01-19 Thread Andre

Hello, thank you all for many helpful posts.

I tried to replace all getters and setters with member variables and
asteroids[i], bullets[i]... with corresponding asteroid,
bullet... variables.
Though this is very important issue, as I supposed, this doesn't
improve FPS in my case.
I agree, that keeping an array of all objects, is not a good practice.
But I want to keep my example as simple as possible, of course in real
game this all should be replaced with more reliable code.
But, when I only draw a few objects on the screen, and when I see big
difference between update and draw methods, I realise that main source
of performance impact is Canvas's affine transforms and draws.

Best Regards, Andre

[android-developers] Re: Effectively using MediaPlayer and saving resources...

2010-01-19 Thread Nugman

Dont call release when it is still playing. The start() function
returns immediatly. So it could still run.
Release it, when it is finished. If this doesnt work out, create them
once as class members (and release at onDestroy).
Dont forget that a long sound will disturb the ui thread. In this case
you have to create a thread for sound playing.
Did you also saw the class SoundPool ?

Try something like this:

final MediaPlayer mp = MediaPlayer.create(getBaseContext(),
R.raw.sound0);
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.release();
});
mp.setOnErrorListener(new OnErrorListener(){
public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
mMp.release();
return false;
}
});

mp.start();

 I'm writing a program for my toddler and I'm running into a problem.

 Here's what I'm looking at...

                                 if(buttonClicked == button1)

 Now that seems to work fine on the emulator.  When I pack it up into
 an APK and put it on my G1 I can only do it 7 times before it force
 closes.  I BELIEVE the memory gets full or something.

2010-01-19 Thread String

On Jan 19, 12:50 am, Dianne Hackborn hack...@android.com wrote:

 Specifically which problems are you having?

Problem is, half the time we don't know. Users post 1* Market comments
saying Force closes on Droid or Doesn't work on Samsung Moment,
and unless you have that specific handset to test on, you're SOL. You
sanity check on an emulator instance of the same resolution and OS
version, and nothing is obviously broken, so where do you go?

The increasing array of hardware devices (with different OS versions,
screen sizes, and crappy vendor-specific UIs) simply exacerbates the
structural problems with the Market, where it's far too easy for users
to downrate apps, and with no meaningful way for the developer to
respond. Put another way, the current Market punishes devs for ANY
flaw in their app, real or perceived, and the diversity of the
device ecosystem is bound to generate such flaws.

I recognize that nobody (including Google) can force OS upgrades to
existing devices. That responsibility lies with manufacturers and
carriers, and all too often, they shirk it in favor of selling the
next handset of the week. Perhaps Google could apply some pressure,
perhaps not. At the least, please ensure that Google Experience
devices have sufficient RAM to enable future upgrades; I'm still
bitter about the G1's memory limit, which makes me feel like I'm being
punished for being an early adopter.

What Google CAN do is improve the flippin' Market. It's routinely
mentioned as one of the weakest links in the Android chain; the
upgrade with 1.6 was a step in the right direction, but many more are
needed, benefiting both users and developers. Addressing some of the
many Market issues on b.android.com would stop so-called
fragmentation issues from being magnified the way they now are.

Google can also slow the frenetic pace of new OS releases, to allow
both devs and handset vendors a chance to catch up.

Finally, I'd really like to see Google sponsor some sort of hardware
support for devs. The recent Developer Labs were a good start; they
should be recurring events at the very least, ideally an ongoing
service where registered devs could stop by a Google office at any
time and test on hardware which they can't afford to buy themselves.
Some sort of loaner program or DeviceAnywhere-style service might also
be possible.

What I'm NOT opposed to is the proliferation of Android devices in the
wild. I believe it's one of the ecosystem's real strengths: the
diversity and choice in hardware. I'd love to see a WIDER range
available, from cheap QVGA PMPs through 10 touchscreen tablets and e-
readers. There's a lot of untapped Android potential out there, and
every new class of device opens up a new market segment to buy my
apps. :^) Growth is good.

Hello Robert.

I want to thank you for sharing your experience with beginners, your
dev journal is extremely helpful!

I will change my code to work with Matrix as you suggest and post the
result here...

 The little stuff definitely adds up and helps but when talking about
 such a small number of objects, I don't think it will double his FPS
 to fix.

 First of all, thanks Andre for actually posting your code so that we
 have some context to work with and I'm also glad to hear that you've
 read my dev journal :)

 Upon first glance, I'm thinking that it's the transforms that are
 costing you so much.  Can you try this for me?

 Create a field Matrix that you will reuse for every entity/object
 draw.  At the beginning of your draw method, set the Canvas's matrix
 to that one.  This will stop all of the Matrix allocating that you're
 ending up with.  Every time you call Canvas.setMatrix(null), it nulls
 the matrix out, but then when you use a matrix function like
 Canvas.rotate(), it will create a new Matrix again, so you're
 instantiating lots of objects within your draw call and that's the
 first thing you'll want to stop doing.

 Now, instead of calling Canvas.setMatrix(null), you can just call
 myMatrix.loadIdentity().  That will reset the matrix and will make it
 so that anything you've done with it before that call is gone.

 I load up a default Paint() to use for bitmap draws, though after
 looking at the Canvas source, I don't know if it matters because it
 passes a 0 into the native method and I didn't look any further into
 the source.  If you want to be sure that you're not antialiasing or
 anything like that, use a default Paint() instance for drawing bitmaps
 and do not set antialiasing or anything like that on it.  That will
 cost you.

 Also, the surface your drawing on is opaque, not transparent, right?
 It'll cost more to draw onto a transparent surface.

 I'm also wondering if something screwy is going on, like somehow the
 bitmaps you're drawing are much bigger than you think they are.  I'd
 throw some logging in of Bitmap dimensions when they are loaded so you
 know exactly how many pixels are being copied.  Perhaps you'll find
 something awry there.

 If you're still having problems, I recommend isolating calls to see if
 any one thing is hurting you more, then investigating it.  It's hard
 to test everything you've got all at once for performance.

   Lets look at two methods:

   They both use getters instead of members, and asteroids[i] instead of

   (Canvas canvas) is also use canvas calls, and I think this is most
   heavy part, becouse:

   updateSpaceshipPhysics();
   updateAsteroidsPhysics();
   updateBulletsPhysics();
   checkForCollisions();

   takes ~1-5ms to perform, and:

   drawSpaceship(canvas);
   drawAsteroids(canvas);
   drawBullets(canvas);

   takes ~25ms to perform (and even more, if I increase number of
   asteroids or start to fire bullets)

  yes, i know, thats why you should optimize your draw*(Canvas) methods.

  now, after changes, do you see any changes in FPS?

[android-developers] Re: ATTENTION ANDROID TEAM: Take back control of Android.

2010-01-19 Thread Piotr

That's what I'm talking about !

We do not know, where problems are, when software works on clean
Android and do not works on some devices.

For example: Hero's UI's is BUGGY as hell (for example, keyboard
events are not fired correctly).

Another example: why Samsung's GPS is working not the same as in SDK,
G1, Magic and Hero ? Why it does not fires all GPS events properly ?

These small differences often make our apps unusable.

Besides, (Dianne), just look at Market ! Read comments of users of
Google Maps or other Google apps. There ARE a lot of users reporting
FORCE CLOSE for some Google Apps.

It is not just a my app problem. It is a whole Android platform
problem. I do not know, maybe some bad design, or just maybe platform
is too open for every stupid mutha.. sorry, phone manufacturer. I
know, they are not interested in creating really nice working, 100%
Android compatbile device. They just want to grab our money.

So, if Google's applications are force closing.. how the hell, my app
could be better ?

It could not.

Programming Android is funny, but testing your code, making it run on
every device available, is going to be MISSION IMPOSSIBLE, especially
for small developers.

Waste of time.

When this works, could we expect it to also work for uses-permission, as

and you are sure that your bitmaps (asteroids, bullets, space ship)

setImageURI(Uri.parse(http://abc.com;));

[android-developers] Re: AdWhirl - any experience with it?

2010-01-19 Thread westmeadboy

You can find out how to do all that by going to the appropriate
website - admob, quattro etc. They all have good instructions on that.

I can only really speak about AdMob because I havent used the others
much. There, you get paid per click but each click is not necessarily
worth the same amount. Location, for example, plays a major part. A
click in China might only bring you 1 cent, but in europe perhaps 10
cents. I think it also depends on supply and demand of the ads
themselves.

Typically, a developer might be getting something like 1USD per
thousand ads displayed. Again, they're are not paid for displaying
ads, its just that it usually works out about that amount (from my
personal experience and having read the experience of others).

The range would be something like 0.20USD to 5.00USD (per 1000 ads
displayed).

And then there is the fill rate which is the percentage of times
your app requests an ad and it is successfully displayed. I've had
fill rates from 10% to 99% but have heard some people talking about
1%. This seems to fluctuate all the time and obviously has a massive
impact on your revenue. I was getting about 90% over the chrismas
period but now its down to about 30%. I guess there is less
advertising out there. But suppose that 50% is normal, then that means
you need to halve the figures above. i.e. about 0.50USD per 1000 ads
requested.

Note, you can just refresh the ads more often to improve your revenue.
AdMob will prioritise serving ads to publishers they expect to get a
better return from. Its not uncommon that an app using AdMob will be
showing no advert most of the time, and this is because AdMob believe
their ads are better off being displayed elsewhere.

[android-developers] Re: ATTENTION ANDROID TEAM: Take back control of Android.

2010-01-19 Thread OldSkoolMark

Device diversity is both a blessing and a curse. For the variety of
reasons already mentioned, even a well-designed infrastructure is not
going to provide absolute confidence that apps will work on
'compatible' devices that haven't actually been tested. 10 years ago
we saw the same problem with WAP phones, and a bunch of startups took
on the challenge of adapting applications for arbitrary handsets.
Android addresses the device diversity issue head-on, but I fear that
we may be in for another messy round of application adaptation unless
Google provides more support to developers. The idea to have a testing
lab where app developers can walk in and test on a wide range of
devices is a good start.

Adding a button to the widget is just a matter of putting it in your
layout. In your code, you can attach a PendingIntent to be invoked when
that button is clicked. You can see that in one of the samples out of my
_Android Programming Tutorials_ book:

http://github.com/commonsguy/cw-andtutorials/tree/master/36-AdvAppWidget/

For your case, though, the challenge is in the next most contacted
contact part. Widgets have no real state, so either you would need to
teach the Button's PendingIntent what the next most contacted contact
is, or you would have to keep a file or database table or something that
knows what the widget is currently showing, so you can determine what is
next to be shown.

[android-developers] Hprof dump support in SDK 2.1

2010-01-19 Thread kohlerm

Hi all,
It seems ddms now has a dump hprof button (since 2.0?). Though it
doesn't seem to work
with an Android 1.5 device (HTC Hero) it's greyed out and says that
hprof dumps are not supported on this VM.

I know who to still get the heap dump anyway, but I'm asking myself
Why is that?- Are newer devices really able to dump directly in
hprof format?

2010-01-19 Thread JP

String,
Thank you for taking the time writing this up. Five stars. I just feel
stupid every time I get on the soapbox just to rehash what should long
have been addressed by Google/the Android team.
I have no idea how to get this across. Diane, Romain and who else from
the other side who have been holding out are forced to try rationalize
impossible positions instead of getting some real support from their
own team to get stuff fixed. I've worked in such an environment and
you can take this only for so long until you go look for another job.
This would be the worst possible outcome, but hey, this is how it goes
sometimes. In the end, everybody loses, and, if it mattered, I'd **
totally put blame on management of the Android team ** for not putting
resources on fixing the issues. It only gets worse the more they let
this slip.

  Specifically which problems are you having?

 Problem is, half the time we don't know. Users post 1* Market comments
 saying Force closes on Droid or Doesn't work on Samsung Moment,
 and unless you have that specific handset to test on, you're SOL. You
 sanity check on an emulator instance of the same resolution and OS
 version, and nothing is obviously broken, so where do you go?

 The increasing array of hardware devices (with different OS versions,
 screen sizes, and crappy vendor-specific UIs) simply exacerbates the
 structural problems with the Market, where it's far too easy for users
 to downrate apps, and with no meaningful way for the developer to
 respond. Put another way, the current Market punishes devs for ANY
 flaw in their app, real or perceived, and the diversity of the
 device ecosystem is bound to generate such flaws.

 I recognize that nobody (including Google) can force OS upgrades to
 existing devices. That responsibility lies with manufacturers and
 carriers, and all too often, they shirk it in favor of selling the
 next handset of the week. Perhaps Google could apply some pressure,
 perhaps not. At the least, please ensure that Google Experience
 devices have sufficient RAM to enable future upgrades; I'm still
 bitter about the G1's memory limit, which makes me feel like I'm being
 punished for being an early adopter.

 What Google CAN do is improve the flippin' Market. It's routinely
 mentioned as one of the weakest links in the Android chain; the
 upgrade with 1.6 was a step in the right direction, but many more are
 needed, benefiting both users and developers. Addressing some of the
 many Market issues on b.android.com would stop so-called
 fragmentation issues from being magnified the way they now are.

 Google can also slow the frenetic pace of new OS releases, to allow
 both devs and handset vendors a chance to catch up.

 Finally, I'd really like to see Google sponsor some sort of hardware
 support for devs. The recent Developer Labs were a good start; they
 should be recurring events at the very least, ideally an ongoing
 service where registered devs could stop by a Google office at any
 time and test on hardware which they can't afford to buy themselves.
 Some sort of loaner program or DeviceAnywhere-style service might also
 be possible.

 What I'm NOT opposed to is the proliferation of Android devices in the
 wild. I believe it's one of the ecosystem's real strengths: the
 diversity and choice in hardware. I'd love to see a WIDER range
 available, from cheap QVGA PMPs through 10 touchscreen tablets and e-
 readers. There's a lot of untapped Android potential out there, and
 every new class of device opens up a new market segment to buy my
 apps. :^) Growth is good.

My point is not the theory of sync vs. async but rather the reality

 Another case that we might face is that if a user is traveling in an
 area where the network connectivity is fluctuating.

Exactly, see above.

 In this cases is it not necessary for us to set a proper timeout..?.
 And if the timeout happens in a synchronous manner then it might take
 a long time for the last call to time out.

I use a sequential model to work off the various calls to the server
side over time. This means I didn't have to deal with the problem
you've found and cannot offer a direct answer. There certainly is the
possibility that the first connection blocks the following on the SDK/
Android level, for whatever reason. Some code diving would be in order
to get to the bottom of this. The question could be raised if that's
an effective use of your time, it wouldn't get you anywhere solving
the problem...
From what I can say, I'd recommend to switch to a sequential, managed
model with an adequately low connect and read TO. Android (the mobile
environment in general) isn't like the fixed side where you might have
the latitude to whip up a bunch of threads to work off various tasks
in parallel. The constraints of the environment just don't allow
nearly as much play.

Re: [android-developers] AdWhirl - any experience with it?

2010-01-19 Thread Justin Giles

I agree with Greg (below). I too have a free ad supported full feature
version as well as a no ad pay version. When all the coins are counted, I'm
making more money with the free version than I am the pay version. Almost
twice as much.

In regards to the ad companies and performance, I switch between Greystripe
and AdMob for every other ad in my game. AdMob is outperforming Greystripe
almost 5:1 for the month of January. The month of December, it was only
2.5:1 in favor of AdMob. There are constant fluctuations in the ad market
in terms of fill rate, etc. My fill rate average since I started showing
ads (about 3 months) is around 80%. Not bad, but you do get discouraged
when you see those low fill rate days as well as those low revenue days. My
advice is to try one or two companies over a two month period and see which
one does best for you on average.

[android-developers] Serious android app problem in Canada

2010-01-19 Thread ian

Hey Candroid developers:

Now I hope I'm wrong but it appears as an Android developer in Canada
I cannot sell my apps through the |Market, nor can a Canadian customer
purchase my paid apps.

Are these dire concerns valid?

Maybe somebody from the Google mothership could clarify this important
matter as soon as possible.

The Android Market accepted my developer fee of $25 no problem.  And I
don't recall any restrictions mentioned for Canadian developers or for
paid apps in Canada.

I worry that  hundreds of hours of my work may have been wasted.

Like most Canadian Android developers who share these concerns, I am
considering putting my Android development on hold immediately and
perhaps permanently, and porting my apps to iPhone and/or Pre.

Any other Canucks feel the same way?

[android-developers] Using the AlarmManager as a timing service.

2010-01-19 Thread Android Development

Hello,

I wanted to ask a question regarding the Alarm Manager. I have a
requirements of setting long running timers in my application. The minimum
duration for my timer is 1 hour...and the maximum may be for 4-5 days. This
timer is supposed to run in the background, and when it fires/expires, i
have to show something on the GUI. The timer can be re-scheduled once it
fires based on user action.

What is the best approach for scheduling such long running timers ?

Should i make use of the Alarm Manager ? Or will it be an overkill ? As far
as i know, alarms are retained even if the device goes to sleep and they
wake up the device when the alarm goes off.

I am thinking of using a simple Java TimerTask as an alternative to setting
an alarm: http://java.sun.com/j2se/1.5.0/docs/api/java/util/TimerTask.html.

But i am not sure what will happen to the timer task if the device went to
sleep while the task was running.

What is the best approach here ?

Thanks in advance

Best Regards

Indodroid.

[android-developers] Re: Hprof dump support in SDK 2.1

2010-01-19 Thread Streets Of Boston

It works quite well on 2.1 (and on 2.0, but i'm not sure, i just tried
it on 2.1 with my nexus).

When you do a hprof-dump and have the proper plugins installed in
Eclipse, you get nice charts and graphs of your app's memory usage.

I'm not sure how it works, but i think the device dumps a proprietary
hprof format for Dalvik, which then gets automatically converted into
the 'standard' hprof format and then displayed as charts and graphs.

 Hi all,
 It seems ddms now has a dump hprof button (since 2.0?). Though it

 I know who to still get the heap dump anyway, but I'm asking myself
 Why is that?- Are newer devices really able to dump directly in
 hprof format?

2010-01-19 Thread mastix mc

Hi,

thanks for the hin, I have now changed the launchmode of my activity
to singleTop:

and changed the code to look like this:

// The PendingIntent to launch our activity if the user selects this
// notification
final Intent notificationIntent = new Intent(ManagerFactory

notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Log.d(TAG, Set new message to Notification:  + p_message);
notificationIntent

Log.d(TAG, Setting requestCodeToFixNotificationBug:

final PendingIntent contentIntent = PendingIntent.getActivity(
ManagerFactory.s_service, s_requestCodeToFixNotificationBug++,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

notification.setLatestEventInfo(ManagerFactory.s_service,
p_tickerText,
p_message, contentIntent);
return notification;

Still the same issue! So it did not change anything. :( The app is
running in the background... what the heck is going on here? :(

And @RNekic was right... if the app is not active (running in the

I tell my code to use the old instance instead of creating a new one?

Re: [android-developers] Using the AlarmManager as a timing service.

2010-01-19 Thread Kevin Duffey

Interesting Mark... is there no way to have something wake/start an app up
when a condition occurs? I was reading the blog on Screebl, it seemed like
with the Location support they can activate based on the location or other
conditions of the device. I wasn't under the impression that app was running
all the time.. or that it might be a service running in the background?

On a slightly different note, if you do run a service all the time, that
basically either waits for a timer, or waits for some condition, such as a
GPS location, does that drain battery much? I've not looked into the
Location api, but it sounded like Location would send out a message that a
service could listen for.. as if you could say when the location of this
device is 'around' this location.. call me. Something like that?

Man, so much to learn!!

In cases where I've needed to do this, I call a method from both
onCreate and onNewIntent since, to my knowledge, they don't fire
together; one or the other fires depending on the situation.

In your Intent processing method, you can either pass in an Intent or
have it call getIntent().  Note, if your shared method uses getIntent,
be sure to call setIntent(intent) from within onNewIntent.  For
example:


Option One:

public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

Re: [android-developers] Using the AlarmManager as a timing service.

2010-01-19 Thread Mark Murphy

 Interesting Mark... is there no way to have something wake/start an app up
 when a condition occurs?

Define condition. The OP was inquiring about time, which I would not
call a condition.

 I was reading the blog on Screebl, it seemed like
 with the Location support they can activate based on the location or other
 conditions of the device. I wasn't under the impression that app was
 running
 all the time.. or that it might be a service running in the background?

I do not know off the top of my head if and when GPS position changes will
wake up the device.

 On a slightly different note, if you do run a service all the time, that
 basically either waits for a timer, or waits for some condition, such as a
 GPS location, does that drain battery much?

The key to battery life is that you want the phone in sleep mode. Hence,
depending on how the service is waiting, it may need to force the device
to stay awake, which is awful for battery life.

If you are interested in this subject, you really should watch Jeff
Sharkey's Coding for Life...Battery Life, That Is presentation from the
2009 Google I/O conference. There's a YouTube video of it out there.

 I've not looked into the
 Location api, but it sounded like Location would send out a message that a
 service could listen for.. as if you could say when the location of this
 device is 'around' this location.. call me. Something like that?

That certainly exists, but I have not experimented with it recently, let
alone with the device in sleep mode.

Again, the OP was inquiring about timers, so my reply was focused on timers.

Re: [android-developers] AdWhirl - any experience with it?

2010-01-19 Thread Kevin Duffey

Can one of you guys explain fill rate? I've read the AdMob site.. doesn't
quite click with me. Btw, adwhirl is owned by admob, interesting. So if you
basically need an app that is downloaded 10's of thousands of times to make
a few bucks. By this I mean, if your app is downloaded by 10,000 users, and
they run it once a week, you're not getting many views to ads. I am also
confused as to why admob would want to decide to place their ads elsewhere?
By this I mean.. if you request an ad and don't get one back, that is admob
(or other service) deciding that they don't want your app to have that ad as
often as you may be requesting it... but isn't it money for them? I don't
understand why they would control that. As someone who has clicked on ads a
couple of times, I'd much rather see ads faster than slower.. especially
those that are regarding something I am interested in.

Do you guys know if any of these sites target users? I am not sure if
their SDK is able to actually watch what a user does and try to target ads
for that user. I am guessing not as that would be pretty intrusive on a
mobile device.

On a side note, are any of you guys making enough to live off of with
android.. or is it basically a little spending cash and you just enjoy
writing apps for android? I know the rare apps like iFart on iPhone and
others that make the developer thousands, and in some cases millions in a
short amount of time, but I would rather see a more sustained income coming
in.. at some point your app is going to go further down on the market list..
how do you keep people buying it to keep money coming in? I would guess the
free full version with ads is a better way to keep money coming in than the
buy once and that's it. As well, how do you handle income taxes? If this is
too off topic, I'd appreciate a private mail. I am trying to figure out how
all this works and haven't found any good resource on how the whole keep
your app selling on the market, IRS/income taxes, etc works.

Thanks.

Personally, I'm a fan of Option Two since you might have code

Re: [android-developers] AdWhirl - any experience with it?

On Tue, Jan 19, 2010 at 9:59 AM, Kevin Duffey andjar...@gmail.com wrote:

 Can one of you guys explain fill rate? I've read the AdMob site.. doesn't
 quite click with me. Btw, adwhirl is owned by admob, interesting. So if you
 basically need an app that is downloaded 10's of thousands of times to make
 a few bucks. By this I mean, if your app is downloaded by 10,000 users, and
 they run it once a week, you're not getting many views to ads. I am also
 confused as to why admob would want to decide to place their ads elsewhere?
 By this I mean.. if you request an ad and don't get one back, that is admob
 (or other service) deciding that they don't want your app to have that ad as
 often as you may be requesting it... but isn't it money for them? I don't
 understand why they would control that. As someone who has clicked on ads a
 couple of times, I'd much rather see ads faster than slower.. especially
 those that are regarding something I am interested in.


Fill rate is just the percentage of ads requested versus ads actually shown
(impressions).  So for instance your app might request that an ad be shown,
but AdMob might not have any ads to show at that time (based on their
algorithms), so nothing is shown.  That would cause your fill rate to go
down.  Your total number of requests will always be higher than your total
number of impressions.


 Do you guys know if any of these sites target users? I am not sure if
 their SDK is able to actually watch what a user does and try to target ads
 for that user. I am guessing not as that would be pretty intrusive on a
 mobile device.


I kind of think not.  I can see an instance where they might capture the
device ID and keep a record of what kinds of ads they click, but from my
experience, it doesn't seem to affect what types of ads are shown in the
long run.



 On a side note, are any of you guys making enough to live off of with
 android.. or is it basically a little spending cash and you just enjoy
 writing apps for android? I know the rare apps like iFart on iPhone and
 others that make the developer thousands, and in some cases millions in a
 short amount of time, but I would rather see a more sustained income coming
 in.. at some point your app is going to go further down on the market list..
 how do you keep people buying it to keep money coming in? I would guess the
 free full version with ads is a better way to keep money coming in than the
 buy once and that's it.


Nope, not making enough to quit my day job.  I tend to play it safe though.
I personally don't see this platform lasting more than 5-10 years before the
next big thing comes out and everyone flocks to it.  So, I write my
applications, put them on the market and enjoy what money I get all the
while being grateful that I have job security in my real day job.  Also on
this note, it doesn't seem as if the Android Market in its current form is
able to allow people to quit their day jobs for any length of time.  You
would have to push out a new application every couple of weeks in order to
make enough...assuming those applications actually are popular.  I
personally don't see how a dedicated Android company can make ends meet
currently.


 As well, how do you handle income taxes? If this is too off topic, I'd
 appreciate a private mail. I am trying to figure out how all this works and
 haven't found any good resource on how the whole keep your app selling on
 the market, IRS/income taxes, etc works.


This is beyond my pay grade.

On Mon, Jan 18, 2010 at 10:50 PM, Kevin Duffey andjar...@gmail.com wrote:

 I'd first like to avoid loading different image sizes for each zoom level
 for each item I want to place on the map.



 Here's the thing.. in my app, it shows state parks. If you're zoomed out
 far enough, you're not going to see any parks. Right now tho, as you zoom
 out, all my icons stay the same size and get closer together the further out
 you go, until, as you said, they are crowding each other.. overlapping. You
 can still click on them..but it's pointless because you're probably clicking
 on several at once when you've zoomed out to see the full US. I want the
 icons to show up when the user is zoomed in at a certain level.. and get
 smaller as they zoom out for a couple zooms, then disappear completely.


I would do as Frank suggested and have a min and max zoom level you show
icons for and the range of levels in-between, with a set of icons for each
level. This will look better than scaling your images. When you exceed that
min / max, remove the overlays from the map until the user gets back in the
range.


 I am not entirely sure how to replace icons with different sized images
 as the user zooms out.


Are you using ItemizedOverlay? It has a setMarker() function that lets you
set the image used by the list of items.

Do you know by chance if the draw() method is called several times per
 second like in desktop/windowing/games?


The draw() function is called whenever the view is invalidated and it's
required. Like when you add or remove overlays (or other views), pan the map
around, or zoom in or out. It's called twice each time, once for the shadow
layer, once for the regular layer.

[android-developers] Re: ATTENTION ANDROID TEAM: Take back control of Android.

2010-01-19 Thread Maps.Huge.Info (Maps API Guru)


 Problem is, half the time we don't know. Users post 1* Market comments
 saying Force closes on Droid or Doesn't work on Samsung Moment,
 and unless you have that specific handset to test on, you're SOL. You
 sanity check on an emulator instance of the same resolution and OS
 version, and nothing is obviously broken, so where do you go?

 The increasing array of hardware devices (with different OS versions,
 screen sizes, and crappy vendor-specific UIs) simply exacerbates the
 structural problems with the Market, where it's far too easy for users
 to downrate apps, and with no meaningful way for the developer to
 respond. Put another way, the current Market punishes devs for ANY
 flaw in their app, real or perceived, and the diversity of the
 device ecosystem is bound to generate such flaws.

 I recognize that nobody (including Google) can force OS upgrades to
 existing devices. That responsibility lies with manufacturers and
 carriers, and all too often, they shirk it in favor of selling the
 next handset of the week. Perhaps Google could apply some pressure,
 perhaps not. At the least, please ensure that Google Experience
 devices have sufficient RAM to enable future upgrades; I'm still
 bitter about the G1's memory limit, which makes me feel like I'm being
 punished for being an early adopter.

 What Google CAN do is improve the flippin' Market. It's routinely
 mentioned as one of the weakest links in the Android chain; the
 upgrade with 1.6 was a step in the right direction, but many more are
 needed, benefiting both users and developers. Addressing some of the
 many Market issues on b.android.com would stop so-called
 fragmentation issues from being magnified the way they now are.


While I agree with you 100% about the market being underwhelming for
both the user and developer, there is something you can do about the
feedback comments left on your app.

First, download and install your app to a device from the market.
Then, when you see a comment that needs responding to,  add a comment.
Your comment will appear directly above the last one made. If later on
you see another comment you need to respond to, simply update your
comment. It will move to the top of the stack again. I preface my
comments with: Developer Comment:

There's no guarantee that the poster will ever read that response,
they usually are done by the time they leave a negative comment with
the words uninstall but future downloaders will read your response
and know that 1) you read the feedback, 2) you respond to it and 3)
you're proactive in support.

Here's one I got recently on my Radar Now! app:

Richard and Victoria 01-19-2010 *
I live in Imperial Beach CA and its right by the US/Mexico border so
the app kept reading my location in Mexico. I uninstalled immediately.
Please fix.

Obviously, I have no control over how the cell towers compute this
person's location so there is nothing I can do to fix his problem
other than tell him to move. My response was as follows:

maps.huge.info 01-19-2010 *
Developer comment: Your location is computed using the cell towers in
your area, the only way to improve: disable that service and use gps.

At least this shows I read the comments, have an understanding of the
problem and can respond to the user in an intelligent and thoughtful
way. Richard and Victoria will never read this as that user has
already moved on, but other readers will see my feedback.

[android-developers] Re: ATTENTION ANDROID TEAM: Take back control of Android.

2010-01-19 Thread Maps.Huge.Info (Maps API Guru)

I think there is a fairly easily implemented solution to the problem
of device and OS diversification. I've been using this myself for
months and it works very well.

For Radar Now! I've established a beta test community of users who
have volunteered to try out new versions of the app and even new apps
that haven't been released to the market. It's been an invaluable tool
to diagnose and correct problems before they become a string of one
star FC, sucks! uninstall comments in the market.

The way I established this community was to add a line at the bottom
of the help text that comes up the first time a user runs the app:

Beta Testers Needed!

Approximately one out of 1000 active users has joined the beta
community, around 80 at this moment. They have every possible
combination of device and OS there is, including cyanogen. Users who
have a problem will report it back via e-mail and if the problem can't
be solved by their description, they use SendLog to send me the log of
their session.

I post the beta on the Radarnow.net website, which has logging
switched on to help debugging.

Official Android Beta User Community

What would be a really great addition to the Android developer
community would be the establishment of an official beta user
community. This could take the form of a Google Group, one for each
app, with the app itself in the files section. I'm sure there would be
thousands of users who would volunteer to test cutting edge apps and
help find problems before they become a catastrophe in the market.

A little help from Google will be required to accomplish this, Google
would have to:

1. Endorse the idea
2. Add some sort of language to the market asking people to volunteer
3. Add a check box to the developer console to opt in for a particular
app
4. Add some code to the market so when an app becomes part of this
program, the group is created

There may be some other considerations for Google but I think the
minor work involved would greatly ease the minds and hearts of
developers around the world without the pocketbook to go out and buy
20+ devices and sign up for the services they require.

[android-developers] Constructing shapes from other objects

2010-01-19 Thread Carl Whalley

In graphics packages you can start with a rectangle, make it a
rounded, then say add another triangle and where they meet join them
to create a path, which can then be treat as a single object, e.g.
filled with a gradient. Can this be done with Androids graphics? I'm
trying to make, for example, a speech balloon rect with rounded
corners. The way I described sounds far easier than specifying each
path co-ordinate manually.

2010-01-19 Thread karthikr


This may be slightly off topic,

But still the google team should look at expanding the android market
to different countries.

Seems  apple now has nearly 97% of all mobile application downloads.

When the spp store wasreleased apps were available in around 80
countries and for around the same number of developers.

I have not seen good progress in this regard  from the android team,
15 months since first device was launched and still we have paid
application support for developers and user download in not more than
10 countries.

Is there any plans to improve this at all or is this going to be the
same?

I have been waiting for more than an year to release my app to the
android market and am totally fed up of the same.

Everytime we get a reply The android team is working hard to add
additional support, and we dont even get any approax time frame.

[android-developers] Problem with ListPreference in preference view

2010-01-19 Thread Chris.H

This is my first Android app (which is a soft keyboard, with dvorak
layout) and so far it has gone pretty smoothly (either because or
despite working from the sample code). I've had some problems (with
special/swedish characters) that I've managed to take care of, but
this problem I can't figure out how to solve..

I've added a preferences view to the app for some(/a) settings, I used
this reference: http://www.old.kaloer.com/android-preferences/ and it
worked pretty well (besides some hick up from launching the activity
from a service).

But when I click the list item to edit it, i get an empty dialog
(Title and button is shown right and with the text I set in the xml-
file, but no list, screenshot: http://i49.tinypic.com/2501p55.png ).
I can't see any problem with the program code (which isn't many
lines..) or the xml (the arrays are generated by the Android utils in
Eclipse and the preferences is a mix of auto and manual). You can see
both Java code and XML here: http://pastebin.com/m4c52c3a2 (titles etc
in Swedish..)
(I've also tried a EditTextPreference item, which seemed to work
fine..)

I have also looked at the log/output using adb, and can't see any
problems there either, so I have no idea onto how to solve this...
So i need some help..

[android-developers] is there a way to know exclude the invisible face intersected with a pick ray?

2010-01-19 Thread Jian Chen

Hi guys,

Imagining below steps:

   1. u draw a cube on the screen
   2. the cube can be rotated per x/y axis
   3. then we can picked up the nearest face with the classic method of a
   pick ray
   4. Now imagine there is a hole at the cube's visible face, and u clicked
   the hole
   5. The classic pick ray method will then return u the cube's back face,
   which is not expected by me
   What I really want in this scenrio is not to pick up anything.

I guessed one possible solution is to write a method to know the intersected
point direction(positive face or negative face) of the face.
I wonder if current Android openGL provides such mathimatical functions?

Or is there a shared coding to achieve this?

[android-developers] Triggering dynamically a NUMERIC keyboard with no use of TextView component.

2010-01-19 Thread Lobo

Hi,

Currently, im porting a J2ME app to the Android platform. Ive already
done this process, though some bugs need to be fixed. Lately, Ive been
struggling to solve an issue related with the Android's virtual
keyboard:

My app launches a screen, together with a virtual QUERTY keyboard,
requesting the user to insert a numeric string in a text field. It is
preferable however enabling a NUMERIC keyboard instead of a QUERTY
one. Thus, I would like to know if there's any way to programmatically
provide a NUMERIC keyboard to the user, disregarding at the same time
any existent EditText components.

Note that i want to avoid the use of expressions related to EditText
elements:
android:inputType=“...”
editTextBox.setInputType(int)

The goal here is reaching the same result as for
editTextBox.setInputType(TYPE_CLASS_NUMBER), avoiding the use of
TextBox components.

Ive tried using with no success:

- Configuration class with the KEYBOARD_12KEY constant;
- The InputMethodManager class;
- The InputMethodService and EditorInfo class (EditorInfo.inputType)

Sorry for the size of this message.
Thanks in advance for all :-)

[android-developers] simple web search based on location

2010-01-19 Thread sunny

Hi Folks,
wondering if any of you can help.
This is what I am trying to do:
simple app to get list of addresses I am interested in based on my current
location.

I get the current location using location services. Now, based on this
current location I want to do a search on business places without really
using the SearchManager's triggerSearch. The problem with the triggerSearch
is that it launches the googlemap and show the business address I am
 looking for and it is blocked. I want to get the control back.  I do not
want to launch the map with the listing. all I want to do is the get the
Geopoint of the business address I am interested in using a simple web
search. I tried reverseGeocoding , but it is does not work with business
address. It needs full address. any suggestion?.

Simply put, all I want to do is a simple websearch , say query=whole foods,
los gatos, CA to get its full address. and then use it to get the GeoPoint.


I am stuck and wondering if anyone can give me some pointers.

thanks a ton in advance.
Sunny.

[android-developers] trouble processing java/lang/Object.class

2010-01-19 Thread JJS

I received the following message and found several others who had seen
it but no solution.  So I have included how I finally fixed it.  (I'm
using Eclipse version 3.4.2 and Android 1.5.)

trouble processing java/lang/Object.class:
[2010-01-17 14:32:29 - whatever]
Attempt to include a core VM class in something other than a core
library. It is likely that you have attempted to include the core
library from adesktop virtual machine into an application, which will
most assuredly not work.  If you really intend to build a core library
-- which is only appropriate as part of creating a full virtual
machine binary, as opposed to compiling an application -- then use the
--core-library option to suppress this error message. If you go
ahead and use --core-library but are in fact building an
application, then please be aware that your build will still fail at
some point; you will simply be denied the pleasure of reading this
helpful error message.

The fix for me was to go to my project's properties, select:

  Java Build Path - Libraries (tab)

Somehow, the android.jar had been added, and when I deleted it, all
was good.  Note that the android.jar is included as part of the
Android 1.5 library, so this was a duplication.

How did this happen? I certainly didn't do it.  But my app has blown
up a lot in the emulator, so who knows.

Later . . .   Jim

[android-developers] Strange crashing while using OpenGL

2010-01-19 Thread Ian

Hello,

I am currently developing an application that uses OpenGL with the
Android 1.6 SDK.
I am testing on both a Nexus One and an I/O Device (Magic).

The application runs perfectly on the Nexus.

On the Magic, the application crashes 50% of the time on the first
frame with a segmentation fault (see end of post). If it does not
crash immediately, it runs fine and exits normally.

The crash occurs when calling glDrawArrays for one of my vertex buffer
objects.
Oddly, when I enable lighting and one light, the application no longer
crashes. Unfortunately this is not a solution because the application
runs too slowly with lighting.

I have found reports of crashing with vertex buffer objects when using
non-direct buffers, but I am using direct buffers.

For debugging, I modified my code to Log each gl call before it was
made. Everything looks fine to me but maybe I'm doing something wrong:
http://p5ui5jjnxq.pastebin.com/m2e2c1754

Does anyone have any idea what could be causing the segmentation
fault?
Any ideas why lighting would affect it, or why everything is fine on
the Nexus?
Is there something in addition to using direct buffers that needs to
be done when using vertex buffer objects?

Thanks

[android-developers] SMS appliaction-- would someone would like to help?

2010-01-19 Thread Jack Hsu

Hi all,

Sorry to bother you all. I have a proposal that I want to look someone
to help me to develop a new SMS ( short message system) in Android
platform to replace the SMS in android system. And I would like to out
source. Any one would like to take this job?

this SMS application should be:
1. SMS sending and receiving application software
2. Receive the text or MMS and store into our special design micro SD
card,and would not save in cell phone. hence, user can take this card
insert into another Android cell phone and than can see this SMS or
MMS which installed this new SMS application software.
3. Sending the text or MMS in this application software. however,
before sending, it could encrypt this text via the private key (could
be RSA 1024 bite key or 2048 ) and public key which stores in our
special design micro SD card.
4. When receiving the text or MMS, it could decrypt each time when we
read it. Same, it will get the private to decrypt this text or mms.

This project would ask for the developer who has the experience in
Smart card, PKI and SMS of Android cell phone application. And we also
need the source code.  Any one interests ?  we can discuss the
payment. please email me. m0929420...@gmail.com  Jack Hsu

PS: the special SD card is a micro SD card embeds smart card
controller and Java OS ( JCOP v2.4)

[android-developers] Vertical Text Aligment for Key Label in Softkeyboard example

2010-01-19 Thread Wik

Would there anyway to display the text for key label in vertical
aligment?
For example, display
1
2
3
in a single key instead of 123.
I tried to use \n between the numbers but it didn't work.
Would there have any other way to make the text be vertical aligment
or create a table form inside a single key?

P.S. I want it to be text instead of image.

Thanks a lot.

[android-developers] Re: Accelerometer on Motorola Droid

2010-01-19 Thread PhoenixofMT

I can't provide much on this. I'm not a developer, but I may be able
to provide some insight. I've been wanting to find a way to calibrate
the accelerometers on my droid since I installed the tricorder app. It
bugs me that the X and Y axes are off by about .2 ms^-2 in both
orientations. In my searches for such a calibration method, I came
across this post.

The reason the accelerometers never measure zero is that there is
always at least one axis being pulled by gravity. If the device is
lying flat, the Z axis is pointing at (roughly) the center of the
earth and should measure acceleration due to gravity (9.8 ms^-2). The
other axes should be near zero, but the shoddy factory calibration
makes this difficult. The company I work for manufactures marine
inertial navigation systems that use accelerometers, gyros and a 3-
axis electronic compass and I get to calibrate them from time to
time.The way I do this (using a built in program that I've had nothing
to do with) is to set the box on each side and have the calibration
program take 10 readings from the relevant accelerometer, (it also
takes readings from the electronic compass to help with those
measurements, in case you're also working on a compass program). What
I assume, is that the calibration program sets the reading from each
orientation of each axis at +/- 9.2ms^-2. It probably also compares
the differences in magnitudes of the signals from each sensor to
further sharpen the accuracy, since I do not set these things
perfectly vertical for the calibration. As long as the device is held
in the same orientation within the calibration box and the outside of
the box is square, the calibration program can figure it out.

As for using the accelerometers to measure speed changes, I've been
thinking about that to. It would be cool to, perhaps, augment a GPS
speedometer with the accelerometers. Maybe to provide higher
resolution without taxing the GPS receivers? In any case, its pretty
complicated, I'd have to dig out my physics textbook to find the
formulas. Even then it would probably take me a while to wrap my head
around a combination of three axes. Then there is filtering out noise
from, say, the vibrations of a car

Any way, I hope I've been of some help. Good luck, I look forward to
trying out your app.

 What about if you want to run the application on your DISCONNECTED device?

You need to get the APK to the device somehow. By far the most direct
method is via USB, but if this isn't an option for some reason, you
still need to bridge that gap. Some possibilities:

- Copy the APK to an SD card on your development computer, then mount
that card on your phone and open th APK file using a File Manager app.
- Upload the APK file to a web server, then browse to its URL using
the browser on the device.

There are probably other means, but you will need to get the APK file

[android-developers] Impossible to create socket inside Service

2010-01-19 Thread Thomas Geulen

Hi,

i have a big problem with my Service.
My Service-Class overrides the onStart method inherited from Service.
I can not create a socket with a specific address and port inside this
Service. Every time my application hangs there and the emulator shows
a message box that there is no response from my application.

All i want to do is to create a socket in the OnStart-method:

public void onStart(Intent intent, int startId) {
SetServerAndPort();
try {
this.tcpListener = new Socket(this.serverAddress, 
portNumber);
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

Internet permission for the application and especially for the service
are set.
Can you tell me what´s wrong here?

Thanks in advance

[android-developers] Moving Objects.

2010-01-19 Thread TheGlad

Hey, guys, I was trying to find a good tutorial on how to move
objects. Let's say I've created a shape:

public class ActivityTest extends Activity {

CustomDrawableView mCustomDrawableView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mCustomDrawableView = new CustomDrawableView(this);

setContentView(mCustomDrawableView);
}

public static class CustomDrawableView extends View {
private ShapeDrawable mDrawable;
public CustomDrawableView(Context context) {
super(context);

int x = 10;
int y = 10;
int width = 50;
int height = 50;

mDrawable = new ShapeDrawable(new OvalShape());
mDrawable.getPaint().setColor(0xff74AC23);
mDrawable.setBounds(x, y, x + width, y + height);
}

protected void onDraw(Canvas canvas) {
mDrawable.draw(canvas);
invalidate();
}
}
}



Now I want to move the shape in the direction I intend. Let's say I
want to move 20 point down the X-Y direction. Can someone share basic
code of how would you do that?
I'll greatly appreciate it!

In my development environment, more than one USB device can be

[android-developers] Re: onActivityResult is called immediately after startActivityForResult

2010-01-19 Thread Pete Slater

Could you post your exact configuration from your AndroidManifest for
the activities that you are calling from and returning a result from?

The reason I ask is that I am struggling with a couple of activities
in my app. One should be calling the other using
StartActivityForResult but I am getting the dreaded 'Activity is
launching as a new task, so cancelling activity result' problem.

Neither of my activities are configured in any special way... no weird
launchmode or anything but yet it still fails to work for me.

Cheers.

[android-developers] How to speed up Eclipse incremental build?

2010-01-19 Thread Patrick Mezard

Hello,

This is probably more an Eclipse question but pointers are welcome.
Here are some build times for an application, based on equivalent ant
tasks:

clean, build: 17s
incremental build: 8s
debug: 1mn46s

build is equivalent to the ant task target name=build
depends=dirs,resource-src,aidl,compile /, it's basically the
regular Java build without the android packaging action.

I do not use ant in my Eclipse setup to have access to debugger and
other tools. My problem is Eclipse default build action is equivalent
to debug, which is very slow and therefore prevent incremental
builds. I would like to configure the default build action to be
everything *except* the Android Package Builder, while preserving
the ability to make full builds and debugging runs.

Can you tell me how to do this?


Here is what I tried:
- Replace Eclipse build with an ant script. This works fine except I
don't know how to debug it.
- Disable Android Package Builder in project properties. It makes
incremental builds fast but I don't know how to make full builds and
debugging run (since the apk is no longer generated).

Thanks you for any idea

[android-developers] Website to app

2010-01-19 Thread codeninja

Hi all

I know that this was asked before, but he one I found only pointed the
person to the android sdk and documentation and I'm sre that there
must be an easier way for doing what I wanna do.

OK, so I have a mobile site I built specifically for his purpose,
which is sitting online as we speak, but I want to put it in an app..
so basically I want to have something with a browser in it that will
only load my site (hiding teh URL off course creating the illusion of
an app).

Is there any way to do this quickly and easily with having to install
eclipse and all that? Maybe a freestanding application that can just
frame a site like that?

I hope I'm not asking too much..

[android-developers] Re: Best way to launch Messaging app via intent

2010-01-19 Thread dye...@wivsys.com

By setting the action to ACTION_VIEW and type to vnd.android-dir/mms-
sms on the calling intent, multiple phone numbers can be passed via
the address attribute using a semi-colon delimited list:

 After experimenting with the SENDTO action and mms: URIs, I think an
 extra intent filter is needed in the stockSMS/MMS application.

 Currently the ComposeMessageActivity intent filter for the SENDTO
 action and mms scheme is as follows:

 intent-filter
 actionandroid:name=android.intent.action.VIEW /
 actionandroid:name=android.intent.action.SENDTO /
 categoryandroid:name=android.intent.category.DEFAULT /
 categoryandroid:name=android.intent.category.BROWSABLE /
 dataandroid:scheme=mms /
 dataandroid:scheme=mmsto /
 /intent-filter

 Notice that there is currently no provision for mimeType.  This means
 that I can't specify the mimeType of the attachment in the intent when
 I try to launch the mms app via SENDTO. The result of this is that any
 image I specify via intent.putExtra(Intent.EXTRA_STREAM, imageUri)
 gets ignored.  The messing app opens but with no attachment.

 If I specify both the URI scheme (mms) and the Mime Type (image/
 jpeg) via intent.setDataAndType() with action SENDTO, the intent does
 not resolve to anyactivity.

 It seems a bit pointless offering support for the mms scheme, but
 providing no way to provide an attachment.  To fix this I suggest that
 a new intent filter be added to ComposeMessageActivity as follows:

 intent-filter
 actionandroid:name=android.intent.action.SENDTO /
 categoryandroid:name=android.intent.category.DEFAULT /
 dataandroid:scheme=mms /
 dataandroid:scheme=mmsto /
 dataandroid:mimeType=image/* /
 dataandroid:mimeType=video/* /
 dataandroid:mimeType=audio/* /
 /intent-filter

 If that is a workable solution, any chance of including this in the
 next release of the stockSMS/MMS application?

 Is there a more appropriate forum to make requests forAndroid
 platform enhancements?

 Cheers
 Steve

[android-developers] Service within a Thread? Thread within a Service?

2010-01-19 Thread Flapjack

Please forgive my ignorance, I am new to Java and Android.

I would like to retrieve remote data and display it within my
activity. To prevent tying up to UI, I understand that I can do this
in another thread. (I thought I could just-as-well fetch this remote
data from within a service, but that appears to tie up the UI thread
also). So now I'm beginning to think I need to either run the logic
from a new thread within a service, or run a service within a new
thread. But which? I have found many examples online of running new
threads or services, but I have yet to find an example of both at the
same time.

[android-developers] How to feed MediaPlayer with AMR chunks properly

2010-01-19 Thread Marek

Dear folks,

I did some research through the forums and there are similar questions
but unfortunately still without answer.
My goal is to stream AMR stream which I'm reassembling from udp
datagrams.According to the API there's officially supported streaming
using AudioTrack, but it's supporting PCM only.
-- is it possible to convert somehow amr into PCM on the device?

I tried also to point mediaplayer.setDataSource to some URL - I did
some testing before going in this way, I pointed to an URL with amr
file and I could see that the mediaplayer is trying to buffer first
and starts playing without downloading the complete file, but..
- it's playing on the device with wi-fi, when I disable wi-fi (stays
with edge), I get (1,-10) error - preparePVMFErrCorrupt
EVEN if this will work, do I have the guarantee that the buffering
won't take too long? (I've seen buffering cca. 10kB, which is with
12.2kbps few seconds, far away from the real-time feeling)

How about ParcelFileDescriptor? If recording can provide the recording
stream via socket, is it possible to point mediaplayer to such a
socket too? In my test, it failed..

Any other ideas? Your help will be much appreciated!
Cheers,
Marek
