Re: [android-developers] Re: App Inventor to Market

[Dan Sherman]

Unfortunately, thats more of a sort, and less of a filter...

Now, if we could only say "Only items 4 stars and above", thats a different
story..

Re: [android-developers] Re: Game Stuttering

[Dan Sherman]

As far as I'm aware (someone correct me if I'm wrong), primitive types have
no effect on garbage collection, especially local variables.

A great example is:
List items;
for (Item i : items) {
// do something
}

When running will cause garbage collection, as each time that loop is
called, it allocates an Iterator.  However the following would not.

for (int i = 0; i < items.size(); i++) {
Item it = items.get(i);
}

Avoid allocations.

Allocations = garbage collection.

We've been having issues with some users upgrading their firmware, and
having a different device ID after upgrading (which just started within the

heard any complaints from Incredible users...

Mobile carriers are almost all running NATs, you most likely won't be able

Re: [android-developers] Re: Ads in apps... How to successfully generate a larger revenue?

[Dan Sherman]

I would imagine their tax lines look something like this:

Client --> Google :: $1.00
Google --> Developer :: $0.70

Google's taxable income: $0.30

Note that they don't explicitly tell the government "We paid XXX to
developer Y", they just note that the money left their hands, and that they
shouldn't be taxed on it.  Essentially, its your responsibility to mention
that you received the money.  If they wanted to track that cash, should be
very easy to see :)

[Dan Sherman]

I would very seriously suspect that they report it.  I remember having to
give a social-security/tax-id to Adsense when signing up.  And just thinking
through their tax predicament (bringing in tons of money, and seeing a lot
of it go straight back out), they're going to need to keep records, and
report as to where that money went out to.  Mostly so they don't have to pay
taxes on it (was your profits, not theirs).

 I'd love to have that much 7 days a week coming in. That would supplement 
 my
 income nicely. :) Second, slightly off topic, but directly related to
 revenue.. with that much coming in, or say even more if you had like $1000 
 a
 day coming in, what do you do about income taxes? I was told by some that
 google doesn't send any money making info to IRS.. so essentially there is
 no way for IRS or any tax/government to track how much you make. I am
 probably a long ways off from earning $1 a day.. but I am curious how you
 handle this issue. Is it on faith that you pay taxes... and mind you, you
 can shoot a private email if this is something that you wouldn't want to

 I would rather be legit... but am interested in how this is done. Living in
 California I already lose half my paycheck to taxes between state and
 federal.

 The ads that are done in games, don't they have to be clicked on to earn
 money? You said you have 60,000 users, do a lot of them click the ads while
 playing a game? Or even in a splash screen or game-over screen? Or do you
 earn money just by showing the ad? I would hope both.. clicks == more 
 money,
 showing == very little. But if you get nothing from displaying the ad.. 
 that
 seems ridiculous... because you are advertising for that ad.. the user is
 seeing that ad.. even if they don't click it, it may trigger them later to
 look it up, etc. If you do make some money off of each ad displayed... how
 does it work? I mean, you could write a robot app that made it seem like
 10's of 1000's of people were at least seeing the ad. There must be some 
 way
 that admob and others avoid "cheating" and losing money.

 Lastly, I thought things like admob required an ad all the time? You can
 control when/where you display it? I thought admob was a small banner ad at
 the bottom of the screen all the time.. and it's sdk/api controlled how
 often an ad was displayed? What level of control do you have over say..
 putting ads during game play, or just on the splash screen and 
 end-game/high
 score screens? As well, how targeted are the ads? Do you send data to admob
 about the user playing the game that helps them target ads?

 Thanks.

Re: [android-developers] Re: Suspicious TCP RST packets while device is sleeping.

[Dan Sherman]

> Is it the delay in discovering the disconnect that's the issue?

Exactly...

The connection stays open to accept data from the server.  There are
definitely points in time when this wouldn't happen for a few minutes, and
if the connection dropped, that wouldn't be a problem if the client noticed
the disconnect immediately (it would just reconnect, and start waiting
again).  However, when the device sleeps, it doesn't see the disconnect
until it wakes up (possibly hours later)...

After a bit more research, it looks like if the client holds a wake lock
infinitely (just for testing), it gets the reset packet immediately when the
connection is killed, and re-connects immediately.  However, if the device
doesn't hold the lock, and goes to sleep, the reset packet is dropped
somewhere...

Anyone on the dev team able to explain that functionality
(intended/unintended/workaround?)

Re: [android-developers] Re: Suspicious TCP RST packets while device is sleeping.

[Dan Sherman]

Hey Bob,

Thanks a lot for the response :)

After a few more hours tonight working on the problem, I've got a bit more
information to present.

>From everything I'm seeing, it looks like the issue has to do with NAT'ing
at the network level (tmobile I'd imagine).  The connection is definitely
NAT'd, the client sees itself as one outgoing IP (14.130.xxx.xxx) and port,
and the server sees an incoming connection from a different IP/port
(208.54.xxx.xxx).

My best guess is that tmobile is killing the connections at the NAT level
after not seeing traffic running on it for a certain period of time (5
minutes in this case).  This wouldn't be a problem, as you said, a reconnect
works just fine.  And in fact, the higher-level long-lived session control
is already in place, and the client reconnects/etc properly when sensing a
disconnect.

The problem comes in based on _how_ the NAT is killing the connection.
 Keeping a wake-lock on device to prevent sleeping, and watching TCPdump on
both sides shows the server receiving a RST packet, but no RST packet is
sent to the client.  The client sits there, assuming the connection is still
active, indefinitely.  The second it tries to do something (user-prompted,
or via a "ping" timer), it sends a PSH packet to the server, and the server
responds with a RST (it closed the connection when it got the RST from the
NAT).

Obviously if the NAT were to send RSTs both directions, this wouldn't be a
problem, the client would notice the disconnect, and reconnect.  But from
everything I can tell, it notifies the server, and leaves the client
completely unaware that the connection has been dropped...

I understand that the NAT needs to clear out old/stale connections, but
sending a RST uni-directionally seems a bit incorrect to me...

Any ideas?

[android-developers] Suspicious TCP RST packets while device is sleeping.

[Dan Sherman]

Hey guys, trying to track down a rather elusive problem here...

I've been playing around with long-standing TCP connections to a server.

The client opens a TCP connection to the server, sets a timeout at a
reasonably long period (30 minutes), and adds an AlarmManager task to "ping"
the server every 15 (a ping is just a junk packet the server responds to
with an application-level "ack").  Nothing fancy, and everything works
correctly on the emulator.  The client stays connected to the server for as
long as I've left it alone (a few hours easily).

However, as soon as it runs on device, I receive some interesting behavior
when the device is sleeping (CPU completely off if I understand correctly).

If I let the device connect, and go to sleep (can't be 100% certain it is
asleep, but I wait a good few minutes).  And have the server send an
un-expected packet to the client, the client most definitely wakes up,
processes the packet, and sends a response.  The wakeup noticibly takes a
few extra seconds, but this isn't an issue.

The issue comes in if I let the device sleep for a more extended period of
time (somewhere around 5 minutes).  At this time, I see the server drop the
connection as reset, and the client sit there sleeping.  As soon as the
device is woken up (by my intervention), and I try to do any network
actions, it notices the connection isn't good anymore, and starts a
reconnect (hard-coded to reconnect).

I've been running tcpdump on both the client, and the server.

The interaction is as follows:
Server's point of view:
- Client connects (a few packets back and forth, application level, etc)
- 5ish minutes pass (device is sleeping)
- Client sends a reset packet (connection is torn down, expected)

>From the client's point of view:
- Connection startup (a few packets back and forth, application level, etc)
- Device goes to sleep


The client never sees the TCP reset packet.  Once woken by something
external (me, the AlarmManager task, etc), the client immediately sees a RST
packet from the server, tears down the connection, and starts over.

Anyone care to chime in with ideas as to what is happening?  My only
thoughts are that someone in between is killing the connection due to not
seeing any data send between the two after a certain amount of time, however
the time between the last packet, and the RST isn't a consistent period...

This behavior is happening when running a G1 on Tmobile's 3g US network.  It
happens when the server code is running both remotely (machine in Texas), as
well as when its running on local machine (Florida).

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

[Dan Sherman]

I'm not running any sort of beastly machine, quad-core 2.8ghz, with an
nvidia 9800gtx, and almost all the time, emulator performance is lower than
physical device (especially with openGL, but even with canvas).  Might have
something to do with the emulator specifically on linux, so your results may
vary.  As for uploading your APK, just drop it on rapidshare or something
and post the link.

The emulator is not, in any way, going to run the same speed as a real
device.

Run it on a real device and see what FPS you get.  Or if you want, publish
an APK and someone here will run it I'm sure (I'll do it =P)

Re: [android-developers] Re: what is a suitable upper limit for application size?

[Dan Sherman]

Correct, they have 192mb RAM.  However, a good chunk of that is partitioned
away as OS space, etc.

The data partition is 76mb (I incorrectly said 64mb).  Here's a breakdown of
those partitions:

Re: [android-developers] How to best maintain two different versions of the same app?

[Dan Sherman]

We had good luck with our latest project with just checking the package
string.  Naming the project xxx.xxx.project, and xxx.xx.project_lite

And in our Activity subclass, checking for the package name, and setting a
static variable for paid.

Depends how much code needs to switch with paid/unpaid.  For us, it was only
10-20 lines different, so we just wrapped them in that check.

When going to export both versions, we export one, then change the package
name, recompile, and export the second.  Thats about it...

Re: [android-developers] what is a suitable upper limit for application size?

[Dan Sherman]

I've filed a bug report against it, but not sure if its been address in
later releases.

At the time of 1.5 and 1.6, the package installer requires 4x the package
size to be available during an install.

That means, for a 15mb package, the user will need 60mb of free space, or
else the install will fail (adb installs bypass this requirement).  The
error message is also unhelpful: "Installation Failed".

Considering G1's only have 64mb, you're in a rough spot.  We've had a ton of
user complaints with our apps that are around 5.5mb.

Not trying to take anything away from you, just wanted to mention theres
another set of code doing the same remote tracing:

Re: [android-developers] regex error with splitting strings

[Dan Sherman]

Two things:

1) Not positive, but you might be missing delimiters, which would turn that
into .split("/+/"), which would still be wrong

2) + is a regex special character, meaning "1 or more", you want to escape
it as a literal: .split("/\+/")

Again, not sure if you need the delimiters...

Re: [android-developers] Time To Load a Application in Emulator

[Dan Sherman]

>From my experience, depends on the size of the application, and what other
builders you have set up.

For a very basic app (the HelloWorld examples), about 5 seconds on my
computer.

For a large gaming project, 30 seconds for a full build/install.

The machine is a 2.4ghz quad-core, with 6gb of ram if that gives a better
indication.

Re: [android-developers] Avoiding garbage collection for smooth 2d animations

[Dan Sherman]

No matter what you'll see GC being called, there's no way around it (that
I'm aware of).

There are background threads that are doing all sorts of things, which very
well might be getting GC'd.  Theres also a lot of things you can't
reasonably avoid, like allocations from Iterators and such...

Re: [android-developers] 1024x1024 OpenGL Texture

[Dan Sherman]

Just load fewer other textures when making your atlas.

A 1024x1024 image is going to eat up somewhere around 4mb of space, and on
the G1 (and others) you're limited to 16mb.

So it should be just fine, the issue probably is that you have all of your
other resources loaded, and are already taking up the other 12mb.  Instead,
load your other resources one at a time, copy to the atlas, and release the
resource.  You should have enough space without much of a problem..

Re: [android-developers] Re: Droid AVD (2.0, WVGA854) resolution hell

[Dan Sherman]

Yep, we're doing it on our latest release LightUp.

We use the following:
public abstract class UnscaledBitmapLoader {

public static final UnscaledBitmapLoader instance;
public static boolean canScale = true;

static {
canScale = (Integer.parseInt(Build.VERSION.SDK) >= 4);
instance = Integer.parseInt(Build.VERSION.SDK) < 4 ? new Old() : new
New();
}

public static Bitmap loadFromResource(Resources resources, int resId,
BitmapFactory.Options options) {
return instance.load(resources, resId, options);
}

public static void setDensity(Bitmap bmp) {
instance.setDen(bmp);
}

private static class Old extends UnscaledBitmapLoader {
@Override
Bitmap load(Resources resources, int resId, Options options) {
return BitmapFactory.decodeResource(resources, resId, options);
}

void setDen(Bitmap bmp) { }
}

private static class New extends UnscaledBitmapLoader {
@Override
Bitmap load(Resources resources, int resId, Options options) {
if (options == null) options = new BitmapFactory.Options();
options.inScaled = false;
return BitmapFactory.decodeResource(resources, resId, options);
}

@Override
void setDen(Bitmap bmp) {
bmp.setDensity(Bitmap.DENSITY_NONE);
}
}

abstract Bitmap load(Resources resources, int resId,
BitmapFactory.Options options);
abstract void setDen(Bitmap bmp);
}

And then put all of our resources in just the normal drawable folder.  This
will sense if the code is old (1.5) and just do a normal load of the bitmap
(1.5 doesn't do any scaling)... If its a new version (1.6+), it will set the
options for having an unscaled bitmap loaded.  The setDensity wrapping is
the same idea (we needed to set the density explicityl for some images).

Hopefully that helps :)

1.5 will not use the drawable-nodpi.  As it's not even aware that that is a

Re: [android-developers] Re: Best practice for P2P handset networking

I think you're correct though, true WAN p2p would require some sort of
piercing/punchthrough.  But local p2p should work fine.

Re: [android-developers] Re: Best practice for P2P handset networking

[Dan Sherman]

As far as I'm aware, XMPP isn't true P2P, it uses a central server to relay
messages between peers.  If that sort of thing works for you, its not really
P2P, and any server/client model will work most likely...

Re: [android-developers] new sdk requires versionCode bump to install?

[Dan Sherman]

Do a Project --> Clean

I've had issues that if I make changes (or hit save) while its in the
process of building/deploying, the next time I try to run, it will fail.

Either add a letter, and delete it, and hit save (forces it to rebuild), or
do a clean.

Fixes it for me :)

Re: [android-developers] Re: Out of Memory Errors starting today (12/10/09)

[Dan Sherman]

Also getting reports from clients that nothing has changed (at least, not to
their knowledge) on their phones.

Having a really hard time figuring out why the number of FC's spiked from
10-20 to 250 (so far) today, with no changes in code over the past multiple
weeks...

Anyone have any ideas?

[android-developers] Out of Memory Errors starting today (12/10/09)

[Dan Sherman]

One of our apps has been running just fine (a few FC's per day, around 10,
for various reasons).  We havent pushed an update in over two weeks, but all
of a sudden today, we've been getting a lot of complaints from users on G1s,
and are seeing a _ton_ of force-closes (175 so far today).  I know there was
a 2.0.1 update for Droid recently, but our complaints are coming from G1
users.

Did I miss something?  Anyone noticing similar issues?

Re: [android-developers] how is a 3G phone assigned an ip address?

[Dan Sherman]

Really depends on the carrier, the vast majority however are NAT'd internal
connections.

Like you said, you'll need to use some tunneling/NAT punchthrough to be able
to do p2p.

Re: [android-developers] Architectural design question

[Dan Sherman]

You don't really have an option to have them bundled at install time.

Packages require that 4x the package size be available at install time, and
many devices don't have that 96mb of space (much less, that amount unused)
to even install it.

Re: [android-developers] Can anyone tell me ONE app that shows up in Android Market on HTC Tattoo

[Dan Sherman]

But if you're switching your development efforts, why would you need the
names of apps?

Also, blatently stating that you're planning to pirate apps might not be the
best of ways to get help...

Re: [android-developers] Re: ADC2 Results?

[Dan Sherman]

Thank you for participating in the Android Developer Challenge 2. The
results are in, and unfortunately, your application ProjectINF ADC was not
chosen by users and judges as a prize winner. We appreciate your
participation and hope that you will upload your application to Android
Market for users around the world to enjoy. Please note your application
will not automatically appear to users in the Android Market, so you'll want
to publish it when you're ready (http://market.android.com/publish/).

Same here,

Good luck guys :)

Not sure exactly where you're reading that (unless you just missed a few
very important words), direct quote from:
http://code.google.com/android/adc/adc2_terms.html

* All potential Prize recipients will be announced on *or about* November
24, 2009.
Two very important words there :)

Re: [android-developers] Re: Android Market Anti-Piracy

[Dan Sherman]

Just as a helpful suggestion, you'd be best off tracking based on some
pub/priv key system, which developer issued "evidence", so when the
inevitable happens, you can retract evidence from a certain user.
Otherwise, even with a captcha, this is just asking to be hit hard...

I understand your point completely, but just pointing out a very legitimate
reason for some of those apps would be user stats (flurry, google

Re: [android-developers] Can't receive UDP packets correctly

[Dan Sherman]

We've had issues with UDP packets coming in off the socket non-reassembled.

See what happens with multiple reads, see if you get back the expected
packet length in total...

Re: [android-developers] Re: Gaming on android - somewhat disappointing...

[Dan Sherman]

Just a side note to one of your points:

You mention the example of Metroid weighing in a 8mb, and obviously being a
great game.

There's a few problems with that observation, not that it doesn't have its
merits, just trying to point out some things that might not have been
thought of :)

1) From our studies in Cestos/ProjectINF, slightly over 50% of our users are
on Edge.  Downloading 8mb on Edge takes _way_ too long to be reasonable.
You end up losing a lot of potential users due to time between "I want to
play", and actual playing.
2) If they _do_ decide to download the game, 8mb is a huge amount of space
on limited devices like the G1.  There's also a bug currently with the
market, where applications require 4x their space to install.  In this
example, an 8mb game, requires 32mb of space available (on a 48mb [I think]
G1, thats rediculous).  And the error message states only "Installation
Failed".  So developers would get a good number of emails from users
complaining to "Fix your game".

Again, just some observations regarding the size constraint issue.  Our
games weigh in at 1.5mb, and 5mb with full drawn menuing and music/sounds
(with what we'd like to consider great gameplay), but after releasing a 5mb
game, we're extremely unlikely to do it again because of issues we've had :)

[android-developers] Segfault in what looks like WebView

[Dan Sherman]

Hey guys, we just launched a new game (Super Game Pack) in the market, and
got a segfault on a 1.6 emulator...

>From what I can decipher, looks to be coming from a webview component...  Is
there any way to track it further, or figure out exactly what's causing it?
Its relatively rare, so its a bit tough to reproduce, but if I have a way to
trace it, at least we'll be prepared when it does happen :)

Unfortunately I haven't found a solution.

The delay looks to only affect initializing connections (if you have a 10sec
delay on the emulator, you'll see it take 10 seconds to connect the socket).

We built a workaround in-app that delayed outgoing/incoming packets by a
constant amount.  I haven't seen a way to do it with the emulator by default
however...

[android-developers] Re: how to pass complex objects between activities

[Dan Sherman]

I'm not aware of any such feature, but is it possible to force android to
disregard the stack, and open Activity A regardless? (could solve the
problem, especially if B depends strongly on A).  Could also probably check
for a null variable and send an intent back to A anyway :)

[Dan Sherman]

Yeah, we're running it :)

Their program is almost identical to admob's in the sense that its a
packaged library that you need to add to existing views, and not just an
embedded webview.  Last I checked, they required at least 100,000 daily
impressions for the application, but its possible this has been lowered.

[android-developers] Re: Piracy protection idea

[Dan Sherman]

Unfortunately has a few problems:

1) The user has to have an internet connection on first load of the app.

2) If its via HTTP or some other well documented protocol, could easily have
a hosts entry re-point where to ask for confirmation to a server that just
responds "OK".  This could be overcome possibly with a pub/priv key system
of signing.

3) Should still be possible to get a copy of the apk, and remove the code
block for that check I imagine...

You're going to have a problem with piracy no matter what you do.  Look at
_every_ platform, and every form of copy protection, they all have piracy.
The only exception to this that I can see is hosted services (like World of
Warcraft, and websites), where all of the user data is stored some place
that you have control over, and can check for validity on your side, with
known-good code at run-time.  Any time you put code/logic on a client side,
it can be subverted one way or another...

[android-developers] Re: Free space required for a package install

[Dan Sherman]

Dianne,

Sorry to revive the thread (its been a while), but noticed this got posted
in a different thread:
http://groups.google.com/group/android-developers/browse_thread/thread/d92a41988f9d3428

packageinstaller/PackageInstallerActiviity.java (line 293):

   //compute the size of the application. just an estimate
   long size;
   String apkPath = mPackageURI.getPath();
   File apkFile = new File(apkPath);
   //TODO? DEVISE BETTER HEAURISTIC
   size = 4*apkFile.length();
   checkOutOfSpace(size);

Definitely shows exactly what I was talking about (a 6mb file requiring 24mb
free), and looks like it should affect all installs that go through the
package manager.

We're working on work-arounds in our app (after-market downloads to SDcard),
but this could still be an issue for others, especially with the relatively
small space on the G1 :)

Glad we got it pinpointed, should I submit a bug?

[android-developers] Re: Custom Object Serialization in Android?

[Dan Sherman]

Not sure as to an answer to your question (I'm not that familiar with the
internals), however, as a work-around you could probably do something like:

MyObject arr[] = new MyObject[list.size()];
serialize(arr);
send(arr);

-
recv(arr)
list.addAll(arr);


Obviously abbreviated, and doesn't quite answer the question, but there's
definitely ways to get the data from A to B differently...

You can write any sort of copy protection you like into the application...
Most of our software connects to a server to authenticate before running,
you could do this with serial numbers (distributed however you like).  Its
your application, you can add whatever you like to it :)

I'm not so sure you've fully grasped the idea of white-hat...

Why not just be done with this and add copy protection to your own app?

[android-developers] Re: for Google attention

[Dan Sherman]

I'm not a lawyer...

But Google has absolutely no right to try to litigate on your behalf.  They
can't file criminal charges, they would have to file civil charges, but to
file a civil charge, the defendant has to be wronged in some way.  I
understand they could try "We've been wronged by you damaging the community
in general", but thats shaky ground, its far easier for an individual to
prove they've been wronged when that person has actually violated your
copyright...

Filing a civil suit in small claims court (and lets be honest, with the size
of the android market, you're not looking at anything larger than small
claims court), its like 50$ at your local court to file a suit, and if you
win, you'll get that money back.

If you're seriously concerned about the issue, take a stance and file some
complaints, don't just say "Google, why aren't you doing anything?"...

A possible example:  If you grew fruits, and got a booth at a farmers
market, and someone walked up and stole an apple.  You wouldn't ask the
farmers market to fix it for you, you'd either have to run after the guy,
and get the apple back yourself, or sit quietly.

Just pointing out, I don't think it's necessarily Google's problem.  It
would be on the individual developer level (or on behalf of a group of
developers).  Google doesn't own the licenses to applications that site is
distributing, individual developers do...
