from:"Francisco"

Ok, as told on previous emails, I managed to reduce the heap use even 
more sacrificing image definition on xdpi devices. The good news is that 
most of the OOM crashes seems to gone, but the bad news is that NOT all 
of them and the worst is that this kind of crashes in particular persists.


java.lang.OutOfMemoryError: (Heap Size=49187KB, Allocated=38975KB)

Again, there is more heap available than the one needed by the image 
trying to load. But anyway there is a worse problem here: it shouldn't 
beign using 38Mb in no way neither...


Anyway I have had only two of these in last 24 hours, both in devices 
with Android 4.0.4, both with rare resolutions with a density between 
hdpi and xdpi, and in both cases it happened after ten minutes of game 
play, so it may be a memory leak. The problem, again, is that it only 
seems to affect a few devices that I haven't to test, and I have not 
seen memory leaks in no other, so I think that if the incidence of this 
problem were just about two crashes on a thousand boots, I would just 
ignore it.

Re: [android-developers] Re: OOM with heap enough

You cannot use it all if you have images with alpha transparency, that's 
the case of many images in most games, and so its in my game. Actually I 
already use RGB_565 where I can.

Well, that's what I can see on that stack trace.

Data suggest quite the contrary:

your heap is heavily fragmented, your process have allocated 48MB and 
released a lot (since there is 15MB), that's suggest lots of memory 
operations. My guess is that you are leaking memory between restarts, 
through some caches or other global (static) stuff. After few cycles

memory is correctly freed.

Memory is corrrectly freed after exiting from the game.

Anyway I will try to add code to gather more information from the heap 
for further releases, if it is possible, so I can limit the potential 
causes.


Thanks for your answer,

But you don't know if this is first run hence you cannot make 
assumption about process heap state (moreover other data suggest that 
this is not the case).



Data suggest quite the contrary:

I think that data may suggest a wide number of different things.

If the data is valid (heap size and allocation size) this means that 
at least at some point your process allocated around 48MB total (if 
you check android heap management sources you will notice that heap 
grow algorithm do not excessively over-allocate) and when OOM occurs 
you still have 33MB allocated. All of above suggest a lot of allocation.
Well, as told this may suggest a wide number of different things, for 
example as you implicitly noted there may be a problem with the report 
itself and the data may be not reliable, another option is that there 
may be a bug in the heap management of those devices causing the 
problem. Also having a wide gap between allocated and used heap only 
mean that probably that memory was used before, but you do not know if 
it was used by a number of tiny objects or just by a few big ones. And, 
of course, you cannot infer how many times they were stored and released 
or things like that.


As told before, I will try to put some bugsense code for further 
versions, to see if I can gather more reliable and precise information 
on heap state on these crashes.

Did you check with MAT? Also you may try to verify this theory by 
forcing process termination with System.exit.
I've doing that since half hundred of versions ago, more or less, so I 
am pretty sure about it.

[android-developers] Wrong resolution ???


Hi there,

I have an emulator instance that seems to be reporting wrong resolution, 
but I am not sure if it is a problem of the emulator or may be also a 
problem in an actual device with same setup since I have no one. I use 
this code to get the resolution:


getWindowManager().getDefaultDisplay().getWidth()
getWindowManager().getDefaultDisplay().getHeight()

The emulator tries to be like a Samsung Galaxy Tablet with 10'1 inches 
screen and 1280x800 resolution, with software buttons. The problem is 
that putting it on landscape mode (pressing ctrl+f12, you know), and 
executing my app, it reports following resolution:


1238x752

I would understand that 752 due these 48 pixels being reserved for the 
software buttons, but the 1238 has no sense at all: software buttons are 
put just in one position depending on device orientation, not both...


Do you think it is just an emulator bug or may I found this situation on 
actual devices?


Thanks a lot in advance,

Samsung seems to be a major culprit in designing devices that are 
tricky to create emulators for.  They really need to supply emulator 
images for the devices that don't fall in line with Android standard 
pixel densities.  However as I read recently Google is changing the 
licensing to prevent this.  If you are familiar with the hardware 
industry they do this to differentiate their different models which 
benefits marketing but not developers or consumers.

[android-developers] android.database.sqlite.SQLiteDiskIOException: disk I/O error: COMMIT;


Hi,

I am experimenting some crashes with this exception:

android.database.sqlite.SQLiteDiskIOException: disk I/O error: COMMIT;

I think it may occur by several reasons, including low storage for 
example, or a broken sd card, or so... but there may be another reasons.


The question is:

Is there any manner of obtaining more detailed information about WHY 
this exception was raised exactly?

Re: [android-developers] OOM with heap enough

Hi,

I hardly could use less memory. Devices with high dpi and res needs more
memory so they can use HD images, that's why they have a higher heap limit.
Now if you cannot use all that heap size... it is just absurd!

I rather prefer that the problem were a bug on bugsense and this report
weren't reliable...

I remember reading about a similar issue in the past and experienced the
same issue as well.
From what i recall, but dont take my word for it, even if there is room
in the heap and it isnt fragmented beyond belief, Dalvik first checks if
the heap can be enlarged to include the needed space, instead of trying to
use the space it has free.

Since you're already at 48MB, you've just pushed through the limit with
the new needed allocation (regardless of the fact you have the space), and
Dalvik throws the OutOfMemoryException. I had it happen to me as well.

Only solution i've found? to never get the heap so large it sits on the
edge (stupid bug, stupid solution, i know).

I think Dianne Hackburn mentioned that, maybe a google search will find
it.

Well, it may happen, but the evidence on that is really weak. The game

[android-developers] Heap debugging with bugsense


Hi there,

I can pass some parameters to bugsense so they get reported with the 
crash report in case app crashes. As I have too many OOM in some 
devices, I wonder how I could send some valuable information about the 
heap state with them, you know, things like:


- Maximum heap size
- Current heap size
- Heap memory free/used
- Max size object that can be stored on the heap

And so...

Do you know how could I gather these?

TIA,

Also swearing is not incompatible with coding, I am doing both things at 
same time ;-)

Absurd as much as it is, thats most likely what you got.

If you're so pressed on using so much memory, you can also resolve 
this issue by allocating it in a different manner. This issue is 
raised because the heap grew to 48MB prior to allocating the offending 
bitmap, not because that bitmap is too big... if you can change the 
way you do things so you'll never get to needing 48MB at the same time,
It is unlikely I need so much memory. In all the test I did, I never 
used more than 30Mb. I do not know what determines the step that makes 
the heap grow, but may be I just need 32Mb and the system decides to 
allocate 48Mb by itself.


Anyway we are not sure about this being the source of the problem. As 
told, I cannot discard even that heap information passed by Bugsense is 
inaccurate.


Of course the crash is there, but the reason may be different and have a 
more rational solution.
you'd avoid the issue. This is how i resolved it, just changed the 
order of things i do and used stricter control on my memory allocation 
so i'll never inflate the heap so much. If you have 15mb free at the 
moment of the crash, it might indicate that you never needed to 
increase the heap to that size anyway. Imagine you're playing memory 
sokoban :)

you can also:
 - use largeHeap=true and cross your fingers
This is useful at all? I mean, I do no think such devices will have a 
heap bigger than those 48Mb (that as seen SHOULD be more than enough for 
my app...)
 - use added code to limit the requested bitmap quality dependent on 
heap size. lower quality is better than crashing.
Well, this is more or less what I am doing right now, but it will make 
users experience worse than they should be: they buy a xdpi screen, and 
they will see only hdpi images... :-|


And the worst is that I am not sure that this will solve the OOM 
problems, and some users complain about updating to often -probably 
those that are not affected by crashes-, but it is better than spending 
$6000 in different phones for testing that may -or not- fail for real 
debugging.
 - allocate the needed space on native memory manually. Although i 
haven't done the same, i understand that when using native your limits 
go up
 - Come to terms with random crashes but enjoy your HD backgrounds 
while they show:)

Re: [android-developers] OOM with heap enough


One thing about this...

Do you think this may be a problem of target SDK or so?

This is what I am using right now:

uses-sdk android:minSdkVersion=7 android:targetSdkVersion=15 /

And most of this problems (99% at least) seems to be ocurring in 4.0.3+ 
Android devices...


Does this says something to any Android guru here?

O_o

load it using four bytes per pixel (ARGB) and it should use about

I admit you are right. But I need to calm my psyche before starting

That's a logical fallacy, indeed. I am not getting an OOM exception due 
my app is using too much memory, I am getting an OOM exception due the 
underlying VM does not manage the heap properly.


Of course I can try to use less memory and may be it solves the problem, 
but this not the REAL solution, it is just a WORKAROUND, because the 
REAL solution should address the REAL problem.

And if its happening on your first activity, it isnt a memory leak...

- i dont know if largeHeap is useful, but according to documentation, 
it should at least lower the amount of crashes some of your users 
experience.

Oh, I forgot this... but I will take a look on that docs, thanks.


- if i were your user, i'd take hdpi images rather than crashes. if it 
crashes, i dont use the app :)
Yeah, you are right on this, but the problem is not so simple: for 
avoiding crashes for SOME users, I must release a product with lower 
quality images for ALL of them. In fact, if they were only an 1% of the 
users using older devices, I would simply ignore this bug at all.


Anyway I have already released a new version that uses hdpi images also 
for xdpi devices. This has reduced heap use by a half or on such 
devices, so I expect to have no more OOM crashes, or just 1 on 1000 in 
an unknown device with a custom buggy ROM...

Re: [android-developers] debugging crashes on some systems ( not all )

Hi,

This is one of the worst things of Android development ever. I am facing
similar problems, also most of them with SGSIII, getting OOM crashes with
no apparent reason. I have run the app in several different actual devices,
also different emulator instances, one of them trying to fit as closed as
possible the SGSIII settings. I have reduced heap consumption to the
minimal, but I am still getting these annoying errors.

Now I am considering to buy an SGSIII actual device to test it, but this is
not an option in most of the cases, and it is not clear if this will solve
this problem -may be only some SGSIII are affected, and the one I bought is
not one of them-.

I released a new version of my app last Friday with disastrous results due
to this problem -thousands of uninstalls-. I have did my best since them
improving a lot memory use, writting code for actively recycle bitmaps when
they are not needed and thinks like that, with excellent results (in an
emulator instance with same resolution, density and VM heap budget than
SGS3, I got now a 40% less of peak memory consumption than before). And it
is really frustrating to see that crashes continues after all that effort.

We need something to fight these problems.

Bests,


2012/11/21 Mike Adams adams...@gmail.com

 Hi,

 I have a kind of chat and game client, it connects to a board game server
 and is a tabbed android app.  There is a telnet thread and it feeds
 through concurrently linked queues 3 worker threads that update a game
 board, a text console and i have a lists tab.

 The problem is i've had 2 users now complain that the program has crashed
 on them, one said it froze his phone. I can't be clear if the program
 crashed or if its something with their phones, one was a samsung s3 i think
 the other some kind of acer tablet if i recall.  But how would i evaluate
 this? It's never crashed for me on my tablet or phone.  What kind of things
 could cause a crash like this but only intermittent or on certain devices
 which could have to do with the resources available on the devices and mix
 of what is happening on that device. One user says he always hard stops it
 before running it but it still crashed on him which kind of dismisses its a
 state issue with it being up to long.

 Mike

[android-developers] ICS 4.0.4 emulator image?


Hi there,

I have problems with some devices that uses ICS 4.0.4, mainly with 
Samsung Galaxy SIII ones. I have create an emulator instance to try to 
debug this as closed as possible to SGS3, but I have been unable to 
reproduce the problem at all. I only have ICS 4.0.3 on the emulator that 
comes with ADT in Eclipse, so I rather like to test this in an ICS 4.0.4 
emulator to see if it makes the difference.


Is there any manner to run an ICS 4.0.4 emulator?

TIA,

That's exactly what I write down in my Google+ profile this weekend, so 
I fuuullyy gre with that. ;-)
I was faced with similar heap issues, did the same thing as you did, 
mostly came to the conclusion that the best thing is just to drop the 
bitmaps altogether or reduce their resolutions as much as possible.
You should watch out with Recycling manually as this might cause 
issues in some instances (like when the bitmap is used in a listview), 
i found that just nulling the drawable Callback and making the bitmap 
Purgable was sufficient for GC to work correctly and avoid OutOfMemory 
exceptions.
I did it manually to reduce heap consumption peaks. You know: sometimes 
I need to load different bitmaps for a given screen, but even when the 
object of the previous screen has been already dereferenced, the bitmaps 
it uses has not yet been collected, so by a second I will have bitmaps 
for both screens on the memory. I have noticed that if I recycle the 
bitmaps of the first screen before switching, when I load those needed 
for the second screen the old ones have yet been recycled, thus my heap 
use peak is a lot of lower.


Of course you should be careful on not using recycled bitmaps and things 
like that, but my code is pretty clear and I am not experiencing this 
kind of crashes at all, so there is no point worrying about... we have 
enough to be concerned with actual bugs to think about potential ones... ;-)
When it comes to testing, you can always just use your more 
knowledgeable customers as QA.
I have no doubt that if you develop apps like developers tools or so 
this could be very useful, but I do casual games and most of my users 
does not even fill crash reports, and the few ones whose do put things 
so descriptive as it is not working, and others simply comply on 
comments rating the game with one star and swearing about my mum or so...
Start a beta program with a bunch of users (or friends :) ) that will 
test your app in advance.
That's a great idea that I have had in mind before, but discarded due as 
typical nerd I have not many friends... X-D


But perhaps I could think about any incentive. I will have it in account...
You'll be able to reach a wider variety of devices and catch those big 
issues early on before releasing the app to the public.


Emulators by the way, wont do the job as they dont emulate the 
different hardware specifications of each device.
Well, it is true that they have great limitations, not only for not 
having the hardware, also because some manufactures make their own 
customized Android versions. But they are still useful for testing and 
detecting obvious bugs.


Hope there were a renting mobile service on my town or something 
similar...

There was no new SDK for Android 4.0.4, and hence no new official
emulator. It is conceivable that somebody built an emulator image from
the AOSP sources for 4.0.4, and that this is available for download,
but it will not be through the SDK Manager.

Well, it may happen, but the evidence on that is really weak. The game

with 15Mb of free heap an image of just 1M5 as raw ARGB_ will not

Re: [android-developers] Re: OOM with heap enough

As told to Mark, I do not think so: the game is just starting, loading 
the first Screen at all. Also I have never experienced such problems on 
my own devices or emulators, and I have spent many time watching DDMS... 
of course it cannot be discarded at 100%, though.

Re: [android-developers] OOM with heap enough

Hi,

That has no sense at all. I do not mean that you are not right, just mean
that in such case it is a mighty bug...

Best regards,

2012/11/21 Piren gpi...@gmail.com

I remember reading about a similar issue in the past and experienced the
same issue as well.
From what i recall, but dont take my word for it, even if there is room in
the heap and it isnt fragmented beyond belief, Dalvik first checks if the
heap can be enlarged to include the needed space, instead of trying to use
the space it has free.

Only solution i've found? to never get the heap so large it sits on the
edge (stupid bug, stupid solution, i know).

I think Dianne Hackburn mentioned that, maybe a google search will find it.

Re: [android-developers] Re: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag

2012-11-20 Thread Francisco Marzoa

You are right, it is a bug on Admob that was solved on version 6.1.0, 
and I am using the 6.0.1 exactly the previous one... :-|


https://developers.google.com/mobile-ads-sdk/docs/rel-notes

I should looked at that release notes before... Well, it is easy to 
solve then.


Thanks,

You can of course decompile and patch :)

This error was quite common with one of the previous releases of the AdMob
library. Upgrade to the latest version, it is fixed there. I don't

[android-developers] Emulator parameters for different devices

2012-11-20 Thread Francisco Marzoa


Hi there,

Is there any kind of page or archive or whatsoever that has parameters 
on several Android devices so they can be copied into emulator instances 
to be as close as possible to their config?


It is not difficult to find things like image resolution, display size 
(so dpi), RAM, etc. but other things really important like the max vm 
heap size per application it is not so easy to found.

Re: [android-developers] Re: Remote resources

2012-11-01 Thread Francisco Marzoa

That's the approach I was talking about on my first message, but it's not
so simple as downloading a file. You must also manage by yourself resource
selection on localized apps, for example. And also resource changes among
different app versions.

It is not very difficult, but if there is something yet done and available
in the SDK -it's likely not- or as third party library, it may not worth
the effort to make something fully new.

Re: [android-developers] Re: Remote resources


Hi,

Well, after reading that whole document, I have found that using 
multiple apks have a lot more inconveniences in addition to managing 
multiple builds. In the same document they insist a lot on NOT using 
multiple apks if you can avoid it due these inconveniences.


So in the end it does not look like the best approach neither, but it 
was important to know about even for discarding it, so thank you again.

[android-developers] Reusing gradients in different places

2012-10-17 Thread Francisco Marzoa


Hi there,

I draw a grid on a surface, and each cell of the grid is filled with a 
gradient, so what I do is to create a LinearGradient for each cell, then 
set as a shader for a Paint, and finally create a Rect using that Paint.


Something in the way of:

Paint cellPaint = new Paint();
...
for (i=0; icell.length; i++) {
LinearGradient gradient = new LinearGradient(cell[i].left, 
cell[i].top, 80, 80, Color.BLACK, Color.WHITE, Shader.TileMode.CLAMP);

cellPaint.setShader(cellGradient);
canvas.drawRect(cell[i].left, cell[i].top, cell[i].left+79, 
cell[i].top+79, cellPaint);

}


The problem is that I need to create a lot of LinearGradient objects, 
one for each cell, even when they use the same colors, size, etc. and 
just changes the coordinates because each one is drawn on a different place.


But LinearGradient constructor seems to use absolute coordinates, I 
mean relatives to the whole screen, so a LinearGradient created on x and 
y coordinates, cannot be reused on x2 and y2 (where x2 and y2 are 
different from x and y, of course).


Does someone knows a more or less straight forward manner to solve this 
problem creating just one LinearGradient and then moving it to 
different places as needed?

 Hi,

 I'm reading the book Beginning Andorid Games at the moment.
 For those who don't know the book. It is about writing a framework for
 games. And based on this building some little games.
 Writing the framework and its implementation in one Eclipse project was
 not the problem, and for using it in another project for a game I copied
 the packages of the framework into the game project. For a first success it
 was ok.
 On another example I have to import the framework again, and now I want to
 bind it correctly.
 I read that it is as easy as adding the (framework-)project in the
 projects tab in the Java Build Path tab in the properties of the game
 project.
 When I do that I get rid of the errors and warnings.
 But when I start the app I get a ClassNotFoundException
 When I add the packages dragdrop the packages of the framework and
 implementation to the game project it works.

 I checked-out the sources to the book and when I import them to Eclipse
 the framework is also placed in every project and not only once and then
 linked so that it is maintainable at one place.

 Am I thinking wrong or donig something wrong?

 Thank you,

 Michael

You could have -or simply claim to have, since there is no way for us to 
check it- an eCPM of $200 and you will be still wrong: the problem has 
nothing to see with your eCPM, the problem is that you are clearly miss 
understanding the meaning and calculation of such metrics.


On the other hand let me make you a proposal that I did the other time:

Instead of putting an option for disabling ads, just set them DISABLED 
BY DEFAULT, and put an option for enabling them.


This way you could be sure that the 100% of people that enables the ads 
are very interested on those, so your CTR should be increased to the 
highest values ever, and so you will understand why your theory about 
higher CTR meaning higher income is fully WRONG.

Well, I for one care about eCPM. Ours is currently $2.43. If you have 
a better eCPM then perhaps you are right and I am wrong. On the other

Re: [android-developers] Advertising opt out

 I just want to throw my 2cents here...

 While the math presented here is true, you left out an interesting side
effect: Implementing an opt out can lead to higher click through rates and
higher click through rates draw higher bids from the advertisers meaning
higher revenue / click values.

Are you sure about that? Where is it written?


 The math was based on the assumption that the revenue/click value is the
same for all applications. This is not true. I have two apps apparently
with the same user base and one of them have the 4 times the CTR as the
other and the one with higher CTR brings in about 20% more revenue per
clicks.

Well, my own experience is exactly the opposite: the SAME app released
fourth months ago, over one million total installs, has had a lot of
variation on CTR, and in many cases with a higher CTR and similar absolute
clicks, I have got lower revenue. Even sometimes with a CTR very high, it
seems like I were penalized with even lower revenue per click.


 Higher bidding advertisements appear more often in apps that have higher
CTRs affectively resulting in higher revenue / click figures.

I rather like to see some solid proof on these claims.


 Now it's a different story whether allowing that 1.5% users not to show
the ads will increase your CTR noticeably... I think no, but the goodwill
might counter your small losses. It really depends on the user attitudes.

 Let's be civil here. No one has proposed annoying the hell out of your

 I can agree with several people here.

 Fran and William are right about the math. John's approach does not
bring him more revenue, and likely reduces it by a small amount. CTR and
eCPM are vanity metrics.

 Nonetheless, John's approach is reasonable if it is worthwhile to give
up a miniscule amount of revenue, in exchange for increased goodwill and
decreased support costs. I've been known to give a few refunds that were
entirely undeserved, just because I have better things to do than argue
with customers.

 But William's approach also makes sense. Let's not use words like
blackmail and hostage.  You are offering something of value, ad free use of
your app. In a free market, the user can accept the offer and pay, decide
that the ads aren't really that bad and decline, or even decide to
uninstall your app. No hostages, no blackmail. Certainly there are other
offers you could make to your users, alone or in combination. Since there
is a way to opt out of ads, albeit a paid one, reasonable people are less
likely to complain. UNreasonable people, well, they might still do that . .
.

 I am not using ads for a revenue source in anything right now.
Personally, I wouldn't take John's approach for the simple reason that I'd
never get around to implementing it. I have several hundred things on a
list that I could do to make things better for my customers: features,
usability, content, etc. I think it fair to prioritize such requests above
those things that would make life easier for the people who are unwilling
to pay, neither through accepting ads nor making a purchase.  That puts it
at the bottom of the list which means I will get to it approximately. . .
never.

 I'm not in business to please everyone. Don't get me wrong - I want
those who do purchase and use my products to have a great experience. But
you could release an app with no monetization whatsoever and it would still
get complaints. You can't expect those of us who want/need to earn revenue
to be exempt.

Re: [android-developers] Re: Nexus 7 has no menu button?

Well, bear in mind that I was about to install the application just for
helping you for free, so I am actually not interested on it enough to read
the app description...

Anyway I realized after writing my previous message that N7 has no phone at
all, so that permission has no effect neither... so I installed the app and
it actually SHOWS the menu soft button at bottom right as expected. May be
some users are just special...

 The app is a spreadsheet.  The ability to jump to the phone dialer was a

 numbers in spread sheets and jump to the dialer app to easy calling.  It's
 really quite an intuitive concept when you think about it, I thought it was

Re: [android-developers] Advertising opt out

2012-09-18 Thread Francisco M. Marzoa Alonso

What has no sense at all is to say that the higher the CTR, the higher
the income. Please, let me quote myself on this very same subject on the
third of July:

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

You can be sure that you will get more revenue with 100 clicks on 1
impresions (CTR=1%) than with 10 clicks on 100 (CTR=10%).

And answering to your question, the only thing that it is SURE is that
if you do not show the ads to these users, they will not click on them.
That's really a fact. But it is not sure that people who opt out were
never going to click on your ads anyway.

On the other hand, what do you actually win for putting such option in
your app? Having users that will give you 0 income installing your
application does seem to be a big deal, indeed...

 about how it's funded.

 I get about the same number of comments from people complaining about ads
 as I do from those who rave about the game and say they would have been
 happy to have paid for it with some offering to donate. So I thought I'd
 combine the two and give those who want to throw a couple of dollars my way
 a easy means and offer to take away the ads for the same coin.

 On the Ad metrics, reducing the number of ad requests to increase the CPC
 or eCPM doesn't increase (or even affect) the revenue. It just makes those
 numbers look better.

 Many developers force users to purchase something in order to remove
 advertisements from their apps. While this may seem to be a good revenue
 model, it tends to annoy and anger users. It has some other serious
 consequences as well.

 One of the important metrics in calculating the CPC (Cost per Click) is
 the CTR (Click Through Rate). A low CTR will also result in a lower CPC. By
 forcing users to view ads that they will never click on developers actually
 are lowering their earning potential.

 One way to raise CPC, CTR and customer satisfaction is to allow users to
 opt out of advertising without charging them. It's not only good for
 customer relations but also the bottom line. How many users actually pay to
 remove ads? It has to be a very low rate compared to the number who are
 frustrated and annoyed at seeing ads. The good will alone makes this
 worthwhile. The real benefit is increased CPC and CTR.

 We've recently implemented AdMob advertising in our main app and have had
 virtually no complaints at all. A couple of users have missed the several
 places where we state that Anyone, anytime can opt out of ads and
 contacted us. When they understand the way we've set it up, universally,
 the former angry user is now an ecstatic one.

 In addition, we're seeing excellent CTR and eCPM (effective Cost per
 thousand). I can't say with impunity that our opt out policy is causing the
 high eCPM but it probably is helping.

 Consider free opt out for your advertising supported apps. It's good for
 everyone.

[android-developers] How to deal with random hangs without stack dump?

2012-07-31 Thread Francisco M. Marzoa Alonso

Hi there,

I am facing some random hangs without neither stack dump or force
close message. My app is simply closed without no message about. I am
even using critercism for reporting crashes, but in these situations
there is even no report.

My guess is that something is crashing below Dalvik, at native level, so
the VM has no chance to handle it.

I have been able to reproduce these on my SGS2, but could not get any
valuable information about. It occurs randomly, though I suspect of
SoundPool. I have been able to run the app for more than an hour with
sound disabled without crashing. But the problem is that after that, I
have had it running for more than an hour also with sound enabled... so
my theory about soundpool is a bit weak.

Anyway it used to crash always when it should make a sound, so I do not
discard the problem is still on the SoundPool anyway, but given its own
random nature it is very difficult to determine why and thus find a
reliable workaround.

I am about to fully remove soundpool from my app and use mediaplayer
instead to see if there is some improvement, but in any case I rather
like to know how other developers deals with these random crashes, and
if there is some way of debug them through Eclipse and ADB tools at
least to be more closed to the source of the problem.

Best regards,

You will need to use a different package name for each app version, so you

Re: [android-developers] Storing an array of floats in SD Card

You can use Float.toString to convert these values into strings so you can
write them into a regular text file, one by line or using some separator
(i.e. 1.13:3.1416:8:...) You can load them further and convert again to
float using Float.parseFloat.

If you care a lot about speed and storing space, then you will need to dump
the raw array to a file using a binary steam.

Re: [android-developers] Getting android device Information

2012-07-26 Thread Francisco M. Marzoa Alonso

AFAIK there is no way you could be sure that you are in front of a table
or a phone (or a TV). Bear in mind that in the future there may be even
other different device types.

You better rely on screen density and/or resolution to calculate the
font size. That's what I do on my last casual game -still unpublished-.

So, if you use a size of 10 for an screen that is 800 pixels height, you
may use a size of 20 for an screen that is 1600 pixels height.

So you can do something like:

realFontSize = (getWindowManager().getDefaultDisplay().getHeight() * 10)
/ 800

Anyway I think it should be a more straightforward native way to do this
in most cases using dp or so, but I am not sure about.

Hope a more advanced Android developer could give you a better answer,
but in the meantime you can use that code as a workaround.

Regards,

Re: [android-developers] Re: Do we need images for all versions HDPI , MDPI , LDPI

2012-07-26 Thread Francisco Marzoa

Also another point is the image to be scaled I itself. Some images may lost
important details when scaled down while others won't do it.

Photographs should scale down very will in most cases, but images generated
by 2D design sometimes won't. For example, if you draw an straight line too
thin that it's important for the design, it may disappear when scaling
down. The same may occur with thin strokes. In these cases the unique
approach is to export the image as a bitmap several times at different
resolutions.

 Android's will be optimized more for space/time than would, say, all
 of Photoshop's. Plus, Android's scaling algorithms might change over

 may be overkill for many apps, there will be some whose designers want
 that level of control.

[android-developers] Problem getting id of a resource when using a Library project

2012-07-24 Thread Francisco M. Marzoa Alonso

Hi there,

I am facing problems getting the id of a resource by name when using a
library project:

int resId = context.getResources().getIdentifier(myresname,
drawable, net.iberdroid.mygamecore);

It seems like this always returns 0 when using the project as a library,
but it were working flawlessly while it was an standalone project.

net.iberdroid.mygamecore is where those resources resides, and in fact
they are there.

That code is even executed within the library project package, not from
the android project that links it.

Any ideas?

[android-developers] Re: Problem getting id of a resource when using a Library project

2012-07-24 Thread Francisco M. Marzoa Alonso

I found a solution, but it is a bit weird and since I use a library for
not making repetitive changes on different versions of same game
(tipically free and pay versions), also a bit annoying.

In this context, net.iberdroid.mygamecore is the Library Project shared
by payment and free versions, and net.iberdroid.gamefree and
net.iberdroid.gamepro are the Android Projects for free and pay versions
of the game.

If I change the package name on the previous code by
net.iberdroid.gamefree it works fine. But the problem is that that
code is within the library, and will be used also by
net.iberdroid.gamepro, so putting the package name of the free version
will broken the pay one and viceversa.

So if I want to still share that code within the library, I will need to
get the package name of the project dinamically. So this will do the trick:

|public static int getDrawableId(String dname) {
String pn = context.getPackageName();
int resId = context.getResources().getIdentifier(dname, drawable, pn);
return resId;
}

 Unfortunately I've already done your last suggestion.  The images are
pretty small already.  I'm still not convinced that the streaming would
work.  For one thing, the flicker loops, and for another, the range of
frames changes quite often.  For example:

 If the phone starts upright, we play images 90, 91, 92, 93, 94, 95, 90,
91...

 Then, if you til it, it'll be like 90, 91, 92, 80, 81, 82, 60, 61, 62,
40, 41, 120, 121, 140, 141...

^   ^  ^^

 The carats signify where the accelerometer value has changed so that
the first frame is different.  This happens quite frequently (to make for
a smooth bend) and is completely unpredictable.  As far as I can tell,
we'd always get a hiccup when the accelerometer value changed.

 I'm really hoping that I can do what I was originally asking for.  It
seems so simple to just force the loading of a different set of drawables.

 If I wanted to load the images some other way (not through the
drawables folder) how could I do that?

 On Tuesday, July 17, 2012 12:48:48 PM UTC-4, Nobu Games wrote:

 You still could go with the streaming idea. At any given time you
would have a fixed size amount of frames in memory (let's say 15 bitmaps,
just as an example). As the animation progresses you need to load the next
batch and discard older ones. In order to prevent loading hickups you could
proceed as follows:
 Your window of animation bitmaps has 15 items.
 As the animation counter reaches item #6 you would recycle the last 5
ones and load the next 5 ones that come after item #15
 Loading needs to be done in a background thread (AsyncTask)

 Of course you'd need to add special logic for your case, like allowing
to loop a certain amount of animation frames and starting playback from any
point of the sequence and so on. But this could be done with a fixed size
window of frames.

 I think that's the only sane way to do that based on that huge bitmap
sequence and you could even adjust the window size according to the
available memory. Play around with these numbers in order to get the best
result for your animation.

 By the way, I would just animate the flame itself and use a single,
static bitmap for the lighter. That way you could use a low-resolution
bitmap sequence of the flame and scale it up on devices with less memory.
Lights and shadows could be faked in real time, too, by drawing overlays on
the view's canvas.

 Maybe you can get away with that solution and don't need to implement
a streaming technique.


 On Tuesday, July 17, 2012 9:28:59 AM UTC-5, Matt Schoen wrote:

 Hey, thanks for the reply.

 I guess I should have explained more clearly.  This is a lighter
type animation, which responds to accelerometer input.  The flame flickers
(plays from a start frame on a short loop) and when you tilt the phone, the
start frame is swept through an animation of the flame bending from one
side to another.

 Because of this, I'm not sure I could really stream anything since
I might need any one frame of the animation at any point.  It just occurred
to me that maybe I could store only half the frames and flip them in
software (currently the flip is just rendered into the animation).

 This is why I'm just using a big image sequence (about 150 frames) as
drawables.  Any advice?

 On Saturday, July 14, 2012 12:26:13 PM UTC-4, Nobu Games wrote:

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

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

Re: [android-developers] Is possible to change required features once the apk was published?

I assume you are talking about Google Play, and what you mean is that in
your AndroidManifest.xml file you put wrong requirements.

In that case, I am afraid you need to publish a new version of your apk
file with those requirements corrected, because Google Play gets those
from the apk itself and there is no way you can change the uploaded apk
contents.

Usually your users will be either updated automatically if they choose
it when they installed the application before, or notified about the
existing update so they can decide whether to update to the new version.

 There's a new app on the market that is in 3rd place. The guy basically
 took my apk file and took the sounds out and put them in his. I don't care
 about the public domain sounds, but the others I spent a while creating.
 This isn't big time, but it is annoying. I was under the impression that
 the work becomes copyright when it is created, but I have no proof that I
 made any of them except that my app has been up since Feb. and his just
 came up this month. Can I do anything? I thought about filling out the
 google trademark form but I have no proof except my app is older.

 Anyone have experience with this? or should I just  forget about it. I'm
 looking for a way to prevent him from stealing any new sounds I create, but
 I am still new to app creation/programming.

Re: [android-developers] Android Development Issues

You will have better chance of getting an useful answer on that issue in
Eclipse ADT forum.

 Hello,

 I have been trying to get into android development and I have experience
 programming with Java, so it's not too beyond what I already know. The
 issues I'm having are with getting Eclipse to work correctly for me. I
 installed all the necessary android additions to eclipse and downloaded the
 sdk etc just like every tutorial says. However, whenever I try to create a
 project, eclipse seems to be adding extra files that make it so I can never
 get the application, even the simple Hello Android style ones to work on
 an emulator. And when I try to simply import a completed project, a lot of
 times it won't run on an emulator and I can never get the project exported
 with a signature to see if I could transfer it to an extra android phone I
 have that I was planning on using for application development. My computer
 I am attempting this on is a macbook pro running OS X 10.6.8.

 Does anyone have any suggestions on anything? Every tutorial I look at
 (and I've looked at many) and attempt, ends up not working and I follow
 every step just as they say. It's really frustrating to try to get into
 android programming and not even get the simple Hello World style of
 program to work. Thanks.

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

2012-07-18 Thread Francisco M. Marzoa Alonso

Use they Assets folder instead. Take a look on AssetManager docs.

 Unfortunately I've already done your last suggestion.  The images are
 pretty small already.  I'm still not convinced that the streaming would
 work.  For one thing, the flicker loops, and for another, the range of
 frames changes quite often.  For example:

 If the phone starts upright, we play images 90, 91, 92, 93, 94, 95, 90,
 91...

 Then, if you til it, it'll be like 90, 91, 92, 80, 81, 82, 60, 61, 62, 40,
 41, 120, 121, 140, 141...
 ^   ^
   ^  ^^

 The carats signify where the accelerometer value has changed so that the
 first frame is different.  This happens quite frequently (to make for a
 smooth bend) and is completely unpredictable.  As far as I can tell, we'd
 always get a hiccup when the accelerometer value changed.

 I'm really hoping that I can do what I was originally asking for.  It
 seems so simple to just force the loading of a different set of drawables.

 If I wanted to load the images some other way (not through the drawables
 folder) how could I do that?

 You still could go with the streaming idea. At any given time you would
 have a fixed size amount of frames in memory (let's say 15 bitmaps, just as
 an example). As the animation progresses you need to load the next batch
 and discard older ones. In order to prevent loading hickups you could
 proceed as follows:

- Your window of animation bitmaps has 15 items.
- As the animation counter reaches item #6 you would recycle the last
5 ones and load the next 5 ones that come after item #15
- Loading needs to be done in a background thread (AsyncTask)

 Of course you'd need to add special logic for your case, like allowing to
 loop a certain amount of animation frames and starting playback from any
 point of the sequence and so on. But this could be done with a fixed size
 window of frames.
 I think that's the only sane way to do that based on that huge bitmap
 sequence and you could even adjust the window size according to the
 available memory. Play around with these numbers in order to get the best
 result for your animation.

 By the way, I would just animate the flame itself and use a single,
 static bitmap for the lighter. That way you could use a low-resolution
 bitmap sequence of the flame and scale it up on devices with less memory.
 Lights and shadows could be faked in real time, too, by drawing overlays on
 the view's canvas.

 Maybe you can get away with that solution and don't need to implement a
 streaming technique.

 Hey, thanks for the reply.

 I guess I should have explained more clearly.  This is a lighter type
 animation, which responds to accelerometer input.  The flame flickers
 (plays from a start frame on a short loop) and when you tilt the phone, the
 start frame is swept through an animation of the flame bending from one
 side to another.

 Because of this, I'm not sure I could really stream anything since I
 might need any one frame of the animation at any point.  It just occurred
 to me that maybe I could store only half the frames and flip them in
 software (currently the flip is just rendered into the animation).

 This is why I'm just using a big image sequence (about 150 frames) as
 drawables.  Any advice?

 On Saturday, July 14, 2012 12:26:13 PM UTC-4, Nobu Games wrote:

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

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

 Hey there,

 I've tried to find info on this, but it seems like a pretty esoteric
 case.  I'll admit that I'm probably completely off-base to start, but the
 app is 99% done, so I'd rather not change my implementation from it's
 current state.  I have an animation that I'm using a big list of drawables
 to display, and while it works fine on phones with enough RAM, I get VM
 out of memory crashes on devices with basically 512 MB RAM and below.

 I've found the getMemoryClass() function, which seems to report 32
 for a device with 512MB.  I tried overriding the density value, which
 successfully avoided the crash, but also resized my whole view!  All I 
 want
 is to be able to programmatically tell the view framework to default to 
 the
 low-res images.  Is this possible?

Re: [android-developers] Re: Handling Bitmap Out of Memory Error

GC does NOT take care of recycling Bitmaps, so the answer is that YOU

We are using 640*480 resolution video frames with frame rate of 10

  SGSII has 800x480 pixels, that means that you need about to 1536000

You simply cannot do that without a chrooted device.

Each app runs within its own sandbox and one application cannot do nothing
on other app.

 Hi,


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



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



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



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



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



 Thanks in advance.
