[android-developers] Mac OSX Java error: java.security.ProviderException: java.security.NoSuchAlgorithmException: SunTls12MasterSecret KeyGenerator not available

2017-01-11 Thread Warren Adams-Ockrassa

Boy, I'm pulling out what's left of my hair. One of my Macs has the latest
Android Studio installed with no trouble, and everything works as expected.

The other Mac has been nothing but frustration and exasperation.

It began with Studio not finding its SDK, and never actually having done
anything to download or install it to the ~/Library/Android/sdk directory.
This was silently noted as an error in the initial setup run, but not
highlighted as a critical-stop issue, until of course I tried to actually
*do* anything.

So I copied the working sdk contents from the Mac that had a functioning
install. Success!

No.

Now, whenever I try to load an existing project, or download source sample
files, or even do a clean build on anything, I keep getting whacked with a
trail of errors that *always ends with this*:

*java.security.ProviderException: java.security.NoSuchAlgorithmException:
SunTls12MasterSecret KeyGenerator not available*

A typical console dump on a clean or build is this:

*FAILURE: Build failed with an exception.*

** What went wrong:*
*A problem occurred configuring project ':app'.*
*> Could not resolve all dependencies for configuration
':app:_debugUnitTestApkCopy'.*
* > Could not resolve junit:junit:4.12.*
* Required by:*
* porting_test:app:unspecified*
* > Could not resolve junit:junit:4.12.*
* > Could not get resource
'https://jcenter.bintray.com/junit/junit/4.12/junit-4.12.pom'.*
*> Could not GET
'https://jcenter.bintray.com/junit/junit/4.12/junit-4.12.pom'.*
* > java.security.ProviderException:
java.security.NoSuchAlgorithmException: SunTls12MasterSecret KeyGenerator
not available*

Both machines are running OSX 10.12.2. Both machines are running the latest
Android Studio. Both machines have Java installed.

In my Studio settings, I even tried checking the 'Force HTTP instead of
HTTPS' option, and that didn't yield any positive results either.

I changed my HTTP settings from 'no proxy' (which is correct) to
'auto-detect' (which, as you might guess, accomplished nothing).

Also, I can't seem to connect to the Android Repository (screenshot
attached, with popup showing the error I keep seeing).

I don't have any idea where to go to solve this problem, and the fact that
it's consistent would seem to indicate either a fault in a configuration
file somewhere in Studio, or in the OSX install itself — but in neither
case do I know where to look next.

Pointers and *useful* feedback would be appreciated. Thanks!

[android-developers] Android Studio 2.0 support for AMD-V on Windows (allows built in AVDs on AMD Windows boxes)

2015-12-09 Thread Warren Bare

Hi Folks,

Does anyone know if Android Studio 2.0 will extend support for AMD-V beyond 
Linux to Windows so that a Windows/AMD user will be able to use the Android 
Studio build in AVDs???

Or for that matter, does anyone know if this is slated somewhere in the 
development plans?

I'm using Genymotion, but would much rather use be able to use the Android 
Studio built in AVDs.

Thanks,
Warren

what you please.

2011-01-18 Thread Warren

I am working on several programs and I need some help. I am looking
for a game programmer who is experienced using OpenGL and multiple
threads effectively within Android.

Please do not contact me if you are not already proficient. I need
someone who already has these skills.

Please do not apply unless you can legally do contract work in the
U.S.

If you have these skills and you're interested, please contact me:

[android-developers] How to access mail ?

2011-01-05 Thread Warren

First, I want to get the new mail notification
I used
getContentResolver().registerContentObserver(Uri.parsecontent://
com.android.email.provider), true, service)

when new mail coming the ContentObserver will catch event onChange()

Then, i want to get this new mail content
I used
final String URI = content://com.android.email.provider/message;
Uri uri = Uri.parse(URI);
Cursor c = this.getContentResolver().query(uri, null, null ,
null ,null);

Always have a java.lang.SecurityException:
Permission Denial: reading com.android.email.provider.EmailProvider
uri content://com.android.email.provider/message from pid=429,
uid=10023 requires com.android.email.permission.ACCESS_PROVIDER.

this Permission is define in packages/app/Email/AndroidManefest.xml
and the level is android:protectionLevel=signatureOrSystem

can any 3rd party app access mail content or other way to get content?

[android-developers] Re: force resolution be be higher than 800*480

2010-12-20 Thread Warren

I'm really surprised this hasn't been added to the manifest as an
option.

Physical screen size, size in pixels, and density all seem like
reasonable options for limiting supported screens.

I checked the document about supports-screens, but it seems that
both 480*320 and 800*480screensare considered as normalScreens. I
cannot let my application to support 800*480 and higher screen only.

Do you know how to do this?

What you want is not possible, AFAIK. You can restrict the Market
based on physical screen size, but not some arbitrary pixel
resolution.

[android-developers] Re: Pubish: Target phones with fast hardware.

2010-11-23 Thread Warren

This is not a direct answer to your question, but have you tried
altering your models and images for less capable phones?

I've tried something like this with acceptable results. Probe the
screen size or do a CPU calculation check at startup, then reduce your
texture sizes or model detail accordingly.  Not ideal, but it works.

 I really like this comment:

 *The problem here is not (and should never be) fixed by blocking specific
 devices. If anything, because the list of devices will soon be too large for
 a single person to handle. *
 *
 It should be handled by requiring the correct hardware, if the Market
 doesn't already support that. Barcode Scanner, for example, could require
 auto-focus camera (there are already means for requiring a camera, for
 example; we just need a requirement for auto-focus). Raging Thunder 2 should
 ask for OpenGL ES 2, or a certain amount of VRAM, or whatever.

 *
 *tl;dr the Market needs many improvements, but blacklisting or whitelisting
 devices is a horrible solution. Check for hardware capabilities.***
 *
 *
 Basically android already supports this partially with the uses-feature in
 the xml manifest. However there should be more support for the hardware
 types i mentioned.

 So: How should i do it now? And how is this going to be supported in the
 future?
 My only option now is to detect it on startup and give an alert box to the
 user that it doesnt work on their phone.
 However then my whole sale-model is ruined.

  I have an application that loads a 3dmodel and renders it. These

  Now i get very good ratings (on phones where it work) and very bad
  rating (on slow phones).

  Also: i would like to know the phone type when a user comments. In
  this way i can test it and check whether the user had a valid point or
  not.
  Could you please add this? Same for error reports.

There wasn't much notice, but there was an email that came from
Android Market Support that gave a maintenance window and a list of

[android-developers] reading sound stream to speakers

2010-11-18 Thread Warren

Is there a way to  read the signal being sent to the speakers /
headphones?

I would like to perform actions based on the music playing through the
speakers.  I could write my own media player so that I have direct
access to the sound stream, but that seams like overkill. It would be
much better if I could allow the user to choose any media player and
have my app use the audio output as it's input.

Is this possible? I haven't found anything about it so far.


Thanks,

[android-developers] Re: OpenGL glScissor not working on HTC phones

2010-11-11 Thread Warren

I also tested this on an HTC Droid Incredible with the same bad result
there.

Also, I tested by only drawing over part of the background instead of
using glScissor(). Same result again. It would appear that the OpenGl
library on HTC phones fills the color buffer with garbage on each
swap. Why would this happen?  Does anyone know if HTC changed the
OpenGl library on its phones?  Is there a place to file a bug report
just for HTC versions of Android?

It sure would be great to have an API to give away apps. You could

then when that user visited the market they could download the

would be very helpful to a client of mine.

 My first purchase turned into a return 4 hours later. I'm sure it's

 Luckily I didn't publish anything of great value to the market. I
 emailed the 1st purchaser a few hours after purchase to make sure

 I'm attempting to integrate market licensing to this, that way I can

 also put my friends on test accounts for the time being.

 I am thinking you might be able to let them put the purchase through

[android-developers] Sharing a SQLite database between apps with shareduserid

2010-08-18 Thread Warren

Apparently you can share permission to system resources like protected
database files by using the sharedUserId attribute in manifest files.
Here are manifests from two apps that I have that are intented to
share access to a common database.

manifest xmlns:android=http://schemas.android.com/apk/res/android;
  package=com.my.appA
  android:sharedUserId=com.my.sharedid
  android:versionCode=1
  android:versionName=1.0


manifest xmlns:android=http://schemas.android.com/apk/res/android;
  package=com.my.appB
  android:sharedUserId=com.my.sharedid
  android:versionCode=1
  android:versionName=1.0


The database code is slightly different in each app. The database
properly belongs to appA, so it uses the standard conventions for
creating and opening the database. But appB must do something
different. It looks in the absolute path where the database file
should be:

db = SQLiteDatabase.openDatabase(/data/data/com.my.appA/databases/
mydatabase, null, 0);


I have tried this with success in the emulator, but it fails on a
physical device with
ERROR/AndroidRuntime(17235): Caused by:
android.database.sqlite.SQLiteException: unable to open database file

I am using the debug key to sign the packages, but from what I
understand that shouldn't matter because the keys for both apps still
match.

Is there something I'm missing? Why does this work on the emulator but
not on a Droid?

Thanks for any advice,
Warren

2010-08-09 Thread Warren

I apologize for this thread. I have been having trouble with Google
Groups. I meant to post more but couldn't.

Had I posted the full code someone would have pointed out that my
index array was 1-based when it should have been 0-based.

I think that the openGL rendering code is unmanaged C, so I was
picking up an extra address that had garbage in it. That's why
sometimes the triangles rendered and sometimes they didn't.

[android-developers] Best practice for changing min SDK

2010-08-02 Thread Warren

I have a sizable install base already on some apps with Android 1.5
set as the minimum version.  I want to update the apps to take
advantage of some of the newer features offered in Android 2.0 and
greater. What is the best way forward so I don't break things for my
current 1.5 and 1.6 users?

If I simply update the application with a new min SDK version, will
1.5 and 1.6 users be prompted to uninstall? Or will they just not see
the update?

What about future development that I want to apply for everyone, say a
bugfix. Will I have painted myself into a corner?

Another solution would be to fork and create a new app for 2.0 users,
but that is undesirable for several reasons.

This must be a somewhat common problem. Have you seen any good ways to
handle it?

 Use reflection or check the build version to determine if you can use newer
 APIs.

   If I simply update the application with a new min SDK version, will

 I assume they will not see the update. There's no reason to do this though.

 Not if you do it correctly.

 Yeah, don't do that.

I've got a partial solution to this.  If you use
http://market.android.com/search?q=pname:com.my.package  the url
works, but it does not automatically open with the market since other
applications, like the browser are also registered to handle http://
intents. Instead, the user has to know to choose the market.

[android-developers] Semitransparent text over VideoView doesn't seem to render properly

2010-05-25 Thread Warren

I have a TextView with partial opacity (textColor=#55ff) over a
VideoView, all within a relative layout. I expect the text to be a
light white shading over the video. However, once the video starts
playing, the text looks a dark, dull gray. If I set the text to full
opacity, there is no issue and the text appears solid white.

My guess is that this is some type of optimization to prevent having
to re-alpha blend after every frame update, but I'm not sure. If so,
is there a way to disable it?

[android-developers] Re: Unit Testing : Who uses it ?

2010-04-21 Thread Warren

Writing unit tests first to define exactly how a program will work is
nice if you have the luxury of knowing exactly how the program will
work ahead of time!

I often have a general structure for a program (game) but I don't have
all the little details figured out because things don't always go as
planned. What if I write all my tests for a quadtree data structure
and put in weeks of development only to find out that the quadtree is
not fast enough or eats too much memory?

Instead, I take the approach of working on the features that commit me
the least to a certain way of doing things. And I only write parts of
an application when I need them, not before. This eliminates much of
the waste that happens when you do an about face in terms of the way
your app works.

Front loaded unit testing violates my rule, so I don't do it.


On Apr 21, 2:27 pm, Matt Kanninen mathias...@gmail.com wrote:
 I find that most of my problems are device or user specific issues.
 So to be useful, the unit tests would have to run on the actual
 hardware used by consumers, and would have to emulate the behavior of
 real users.

 Years ago, when I had to write a small bit of generic java code for
 server side logging, reporting, and metrics, that was going to be used
 for lots of different purposes, we used test driven development, and I
 was glad for the experience.

 So basically, I suggest you use the right tool to ensure the right
 level of quality for each specific project.

2010-03-30 Thread Warren

I've written a couple 2D games and the biggest problem is performance.
Drawing bitmaps on a canvas works alright, and it does the job, but
you will not be getting 60 frames per second, or anything close for
that matter. I had to resort to performance tricks that mostly haven't
been used since the 80's and 90's to get my games to be just barely
fast enough to enjoy.

My future development will be using OpenGL, even for 2D drawing, which
is considerably more complicated and may be too much to bite off for a
newbie.

I gotta be honest.. given the various threads on this forum and the beginner
forum about the lacking capabilities of android, be it low latency sound,
better 3D performance, native layer issues, etc etc.. and honestly the only
kind of games I would consider working on are 2D side scroller or top-down
games, and puzzle games. First off, they sell. There are a crap load of us
from the 80s/90s before 3D games became big that still love 2D side
scrollers. They are fun, and as far as I can tell, are not terribly hard to
write and often are smooth playing with little in the way of hiccups causing
problems. The sound requirements are generally minimal and controls are
generally not too demanding. I admire, praise even those of you that develop
more difficult 3D like games! It's a ton of work. Reading Robert Green's
blog about what he did.. man! You really gotta have a passion for the amount
of work that goes into it and possibly with little to no return.

Puzzle games seem to do well, especially over seas, although I still haven't
figured out how difficult it is to post games/apps from USA to other markets
in other countries. I would have hoped it was one big centralized market,
and there would be some way to configure it on each device to look at other
markets/languages/locales if possible, but I am not entirely sure..haven't
looked into it yet.

Anyway, for the OP, do a search in this forum. A few days ago there was a
thread that brought up a couple 2D engines, including Rokon which is pretty
nice. But there were a couple others that were also available and included
native code and such for performance gains. You'll find a couple threads on

[android-developers] Re: In-App Purchasing and the Market Agreement

2010-03-25 Thread Warren

Chris,

I see some potential problems with that approach. I think you need to
think out the process and make sure you have accounted for all the
details.

For instance, you can't charge a different amount for an app based on
what the user wants - can't charge twice as much for two characters.

You can't buy the same app multiple times.


A few points to think about:

Where does the data/logic lie... in the main app or in the add on app?

How would a user specify what character they chose?

How would the process differ for 1 character or 3 characters? What if
the user first buys one, but then decides he wants to buy two more
after the initial purchase?

What if the user uninstalls the app within the free trial period?


All these nagging little questions can trip up the process. Please let
us know if you come up with good solutions to them.

 Yes it was me that had the payment web page into your app but I am about
 90% sure I am going to change to somehow use Market place.
 For the main reason that I don't think I will get near as many people buying
 my characters for my app if they have to enter their payment info into my
 app at my website.

 I think I need to find a way to make my characters available via market
 place so I can use the market place payment. Like I said I am trying to
 design an install app to work with my main app.

 Maybe they buy the install app, download it and the install app knows how to
 download and install my characters from my site based on what the user
 picked within the main app?

 There has to be a way to do this.

 I am good at digging until I find it.

  Like Chris said, the main thing is the user experience. We all know a user
  after 3 seconds of waiting for a page to show up, often goes somewhere else.
  Most people are impatient. Having them fill in all that info they've already
  filled out for their google checkout or paypal account, in a game or other
  app, in my opinion is asking for too much. You don't want to have a game or
  app require personal info to be entered. It's just not going to go over
  well. I honestly don't trust any app out there that asks for my info and
  uninstall it. There is just WAY too much identity theft, stolen cards being
  charged, etc. Most users, I am pretty sure will think along these lines.

  What we need is some sort of Paypal, google checkout or other known vendor
  (not sure how many others are out there) that people are familiar with, and
  are asked for basically a pin or login or something that allows them to pay
  for something without the game/app knowing any of that info. There should be
  no way for any game/app to store their info they enter to access the
  account.

  Games like World of Warcraft, or Xbox 360 where you enter your info already
  when you sign up for something like xbox live, or in WOW you sign up to get
  charged monthly/quarterly.. they have that info already and to play a mega
  game like wow, you must do this, or to access xbox live, you must do this.
  Because that info is already there, in-game purchases, like upgrading xbox
  live, buying xbox money to buy expansion packs to games, etc.. is all done
  very easily.

  To me, there are really only two good ways to do this. One is google
  provides every android device an SDK they can use to do in-app charging,
  that ties to their google account. To use it, a user of an android device
  would do a one time setup of google checkout. Once done, the android device
  can log in automatically and allow one click charging/approval in any app
  on the device that uses the SDK. However, I don't see this being something
  very viable anytime soon.

  The other way that makes the most sense to me and is available sort of
  right now, is using a service like ScoreLoop, OpenFeint, etc, that provide a
  user profile setup..where the user can fill in info including credit
  card/pay pal info at the service site when setting up their profile. Once
  set up, any game/app using that service allows the user to log in to their
  profile. It adds the advantage of storing high scores, achievements, levels,
  etc and you gain the social aspect of things like being able to publish your
  new high score on some game you play to twitter/facebook, and possibly draw
  in other players, etc. The main benefit tho is that the end user signs up
  just once and any game/app using the service is able to allow for micro
  transactions like in-game purchases with one-click approvals.

  Short of those, I don't see any good alternative that will make end users
  of games feel comfortable. I forget Chris if it was you that embedded a
  payment web page into your app... but I don't know how else you'll get
  people to fill in private info like that to buy stuff in game. If the game
  is really good, I can see some players willing to go

This is part of the problem that I originally outlined when I started
this thread. The Market policy allows refunds within the first so many
hours after installing. I can't remember if it's 24 or 48 hours.

I believe if a user uninstalls the app within that time frame the
charge is automatically refunded. So my best guess is that if you auto
uninstall, then you trigger the refund.

Maybe someone could verify this. My little G1 doesn't actually have
service, so I don't/can't buy any apps.

   I think you are right. I think if I do an uninstall on the app before
  the 24
   hour period then it refunds. Thanks for catching that.

   Which leaves only one option.

   The install app can have two buttons on it.
   One to: Remove just the Install app
   and another to: Remove the install app AND the Character

   So the USER has the option of removing either just the install app (so
  the
   phone doesn't get cluttered with apk install files) OR removing the
  install
   app AND the character.

   If they select EITHER button before the the 24 hour period for a refund
  then
   both the install app and the character are removed.

   Which this can all be explained to the user within the install app.

   That should work. I would think?

   Rob
   I just took a look at them. The MAIN thing I am trying to accomplish is
  to
   make my characters available without requiring the user to enter finical
   information again.

    I really believe if they don't have to do that and instead they just
  click
   on submit to buy another character that will make a HUGE difference in
  the
   amount of people that will buy my characters because its a two second
  thing
   for them.

   They are at the DMV for example and board and like the characters in my
  app
   (which they downloaded because it was free), so why not try another
   character for .99 if they just have to click ok??

   If I can just make it as seem-less as possible for an install apk to

 Thank you for the response and exactly what I am designing.

 My main app uses Characters where the information about each character are
 stored via the sqlite database and the images that make up the character are
 stored on phone which my main app uses to load a character when needed.

 I will create an installer app for EACH character. The installer app will
 contain the information for each new character and the images (which are
 under /assets in the apk) and when the user buys an installer app for a
 character it will download, run, read in the images from /assets, write them
 to the phone and populate the sqlite database with the the character
 information.  The installer for each character will also uninstall a
 character by reversing the process.

 So when an installer for character is purchased (though marketplace) and run
 to install the character, then my main app can read the database, read the
 images and run the character.

 I downside is a user can then have accumulate installer apps for each
 character on their phone. So I am applying an option to remove the installer
 app for each character once the character is installed or they can either
 remove it or leave it on their phone.

 The characters can be uninstalled from the installer OR from the main
 program.
 So they don't need the installer app to remove a character.

 That is the ONLY way I can think to abide by the Market rules as they stand.

   You guys really might want to bring up at your next weekly working meeting
   (if you have those) that with all these developers creating everything 
   from
   X to Z for applications there WILL be many legal questions like this one
   that will need to be answered.
   So the developers will know what direction to go in on different issues.

   We don't want to skirt around anything legal, we just need a place to go
   for direction.

   So you guys REALLY might want to set up a place where we can go to get
   these legal questions answered.

   Instead of waiting until they do all the work of developing their app and
   getting it out there and THEN telling them oh you can't do this for legal
   reason ..whatever.

   Just trying to help. I guess I will just send search around to see if I 
   can

   For anyone wondering what the question is go up to my last email on this

This has been discussed in other threads, but there is still no good
solution.

http://groups.google.com/group/android-developers/browse_thread/threa...

Collecting a fee to unlock functionality or to buy virtual items is
not a technical problem. It is straightforward.

However, the Market Agreement severely limits developers' ability to
collect such a fee. It says all fees collected for the app must go
through the Market payment processor.

http://www.android.com/us/developer-distribution-agreement.html

Buying another app from the Market seems the only clearly acceptable
solution. But that is not ideal. It perverts the definition of an
app and causes problems because of the refund policy.

Google, how are developers supposed to handle this situation? Or is
your intention that we simply not do this?

While lawyers may quarrel over the actual document, what is your
intent as it pertains to buying virtual items? For example, charging
$1 real money for 10 in-game gold?

What if only the front end of the game is distributed on the market,
and the features of the front end (the app) do not change with
additional fees? This may be splitting hairs but that's what happens
with legal documents, I suppose.

So what is the intention of the Market Agreement here? Did you intend
to prevent buying virtual items or not?

I would appreciate some clarification so I can proceed knowing the
spirit of the law, so to speak.

Disconnect, I don't think the market agreement is clear on this.

It is clear that if you charge for apps, the payment has to go through
the Market processor.

I'm talking about something different. In this scenario, the app
doesn't change and all functionality is still available to all users.
However, users can purchase virtual goods for use in the game (which
may also be attainable without purchase).

The reason I am asking is not to skirt the rules without being caught.
Just the opposite, I'm seeking clarification up front to avoid
misunderstanding. That is why I'm looking for Google's input on how to
proceed. This has got to be a very common issue. And clearing this up
would help a lot of developers.

I believe that selling virtual goods that can be used in an online
game app does not violate the agreement. I just want to get Google's
take.

2010-03-23 Thread Warren

A technical fix in the Market would be wonderful!


There are a few problems with the way Gang Wars, et al do app
purchasing.

First, users can uninstall within 24 hours. That means you have to
prevent the app from using any new features until that time has
expired and you know it won't be refunded.

Since an app is unique, you don't buy the same app from the market
over and over. So if you want to by $2.00 worth of credits multiple
times, there have to be multiple tag-along apps for $2.00 for you to
purchase - one app for every time you make a purchase.

Also, this really screws with the idea of an app. Google, users,
developers... we all benefit from having a clean, easy-to-use market.
When you dump a bunch of apps on the Market that don't do anything,
you clog up the works and create obstacles for users. Not only are you
adding a bunch of junk apps that don't do anything, you are also
expecting users to understand the difference along with all these
technical details.

Have you ever developed a program and used some class or data
structure it wasn't meant for? I have. I kept thinking it would be
simpler and faster, but in the long run it always ends up biting me.
Yet that seems to be the only clear and safe option here.

It would be much better to offer some technical solution in the Market
for transactions. It would make this whole issue go away. A Market
transaction could be a purchase that is non-unique (you could
purchase the same thing multiple times) and be non-refundable.

 If you then

 would not be for products distributed via the Market, they would be for
 products distributed via your website and would not be subject to being

[android-developers] Re: In-App Purchasing and the Market Agreement

2010-03-23 Thread Warren

An in-app purchase API would be ideal for many reasons. It would spare
users from having to enter credit card information repeatedly. It
could also take advantage of carrier billing where it is available. It
could also provide more revenue for Google.

The question was asked about how else to do credit card charges.

Without an API option, I would likely send the user to a payment
processor like Amazon or PayPal. That way the user deals directly with
a proven system and I don't have the liability of handling credit card
data. Then the processor sends my server a notification of successful
payment. I checked and both of Amazon and PayPal have micro
transaction rates that are far better than the standard $.30 + 3% for
small values.

This is just on the technical end, assuming you have met the Market
Agreement details.


On Mar 23, 12:29 pm, Kevin Duffey andjar...@gmail.com wrote:
 I dont know that I agree Chris.. this issue is not resolved in my opinion.
 There needs to be a definitive response from google, maybe not here, but
 perhaps from a developer that has dealt with this issue.

 The problem with using the market for updates.. is that it's going to flood
 the market with items that end users have to scroll thru to find other apps,
 and they are updates. How the heck is that any good? What google should do
 is provide an update section to the market, so that developers can put
 game expansions, in-game items, etc in that section and NOT pollute the main
 apps/games section of the market. A user will stay on a web page for about 3
 seconds on average before they get bored and leave if it takes too long to
 load. How long will end users scroll through a list of mostly
 add-ons/in-game updates if they are intermixed with all the other apps. I
 know I don't spend that much time, at most I load more a couple of times.
 If the market doesn't get cleaned up, it's going to deter more and more
 users and degrade the overall android experience. I am baffled as to why the
 market doesn't get some sort of regular updates that make it better. As far
 as I can tell, it's a locked app on our devices, but it's an app. Is there
 nobody at google hearing all the negative feedback on how it works and
 looking to better it?

 Like I said above, this is a VERY good opportunity for Google to offer a
 built-in API (or an add-on SDK api so that 1.5+ android apps can take
 advantage of it, not just 2.2+ when it could come out) that provides a
 single sign-on device form.. the device owner only has to fill in their
 paypal/google checkout info once, and all apps can make use of it for
 in-game purchases. Google takes a cut, and makes money. Apple is freaking
 huge due to iTunes.. this would be the same thing for google. Provide us
 with the checkout/purchase API, and take a cut, 25%, 30%, whatever.

 It's evident a LOT of game developers, and even app developers, want to have
 a way to make some money. Microtransactions has been reported on as being
 one of the biggest things coming up for making money. Developers may not
 make much on their games alone, but if their game offers simple in-game
 purchases of some sort, the developer has another avenue of making some
 money. The end result is more developers work this in to their apps/games,
 providing more/longer lasting games, and Android benefits, and google
 benefits too by actually making some money. I see nothing wrong with this at
 all, I think it's fair if google put the leg work into the purchasing api
 that we can all use, they get a cut.

If you follow my example you can add the colors by adding the
components and then recombining them into a color int.

int r = Color.red(bitmap1) + Color.red(bitmap2);
int g = Color.green(bitmap1) + Color.green(bitmap2);
int b = Color.blue(bitmap1) + Color.blue(bitmap2);

int newPixel = Color.argb( 1, r, g, b);


I think one of the PorterDuffXfermodes is for adding also. That would
probably be faster.

[android-developers] Using ListView without ListActivity

2010-01-13 Thread Warren

I want to create a custom list view in my application. I want it to
lay over the top of the application screen, with portions of the
screen not filled by the listview showing the underlying application.

I've been reading about ListActivity, how it can be started to handle
item selected callbacks. I've also read about people simply inserting
onClick handlers into the listview as it is drawn.

I'm trying to decide the best way to proceed. Is it dirty to attach
onClick handlers to the rows of a listview?  It doesn't seem like the
best approach, for instance, it only handles Touch Mode, not the DPAD
clicks. This approach doesn't seem like what the architects had in
mind.

On the other hand, I don't see a good way that I can start a list
activity and still have access to all the application variables I
need.  Do I pass the application in the context and refer back to it
from even handlers after casting the context back to it's original
class?

[android-developers] DroidFanz offering unauthorized paid apps - check yours

2009-12-22 Thread Warren

The droidfanz website offers a download section full of unauthorized
paid app downloads. I found my app there along with about 300 others.
If you have a popular paid app, you may want to check if yours is
listed. You can't see inside the site until you register.


I'm seeing a lot of posts with cracked apps being wrongfully offered
for free or for sale. It is frustrating as a developer because I don't
want to impose cumbersome anti-theft systems on users. I've always
taken the approach that it's better not to annoy real, paying users to
avoid a small amount of theft. But with the amount of similar posts
lately, it seems that the problem may be worse than what I assumed.

Have you contacted law enforcement? You might have a hard time getting
their attention for something small but it is their job to
investigate and prosecute these things. When someone downloads
something they don't have the rights to, that is wrong, but it gets
much more serious when someone is profiting from their copyright
infringement.

[android-developers] Hiding Controls on VideoView using MediaController

2009-12-15 Thread Warren

I am attempting to hide the playback controls of a video view. Can
this be done?

I am developing an application that plays a brief video one time, then
stops. The playback is beyond the control of the user, who should not
see play or pause buttons. I have not been able to achieve this. If
the screen is clicked, the playback controls appear on the screen. I
tried setting the videoview's clickable attribute to false, but that
didn't help. And I don't see any properties to disable the controls.

Any other ideas how to hide the controls?

[android-developers] Market Support Questions From Users/Buyers

2009-12-07 Thread Warren

I get a slow but steady stream of users who have purchased or tried to
purchase my app but have trouble with the market. Typically it's
because the app won't download, or didn't install properly. This is
not the norm. The vast majority of downloads work properly, so it is
not a broken .apk file or anything like that. They seem to be problems
directly related to the market and/or the phone.

I help when I can, but most of issues are beyond my control. Is this
common for other developers?  Do you get support questions related to
the market?  What do you do about it?

[android-developers] Approaches to Security for Web Backed Applications

2009-11-02 Thread Warren

What is the best way to ensure people don't cheat when you use a web
server (or something similar) to handle some of your application
logic?

A good example is a high score board. People play a game and when they
are done, the application sends the score to the server to be
recorded.  However, if someone knows what your server is expecting,
they can craft their own high score and post it to the server
without having earned that score.  There are many similar situations
in which a person could potentially ruin an application by
communicating with the server in ways they shouldn't.

As a developer with a web-backed application, what are the best ways
to prevent this?  Putting a key in the application and encrypting the
message is one option. But it would not be ridiculously hard to crack
even this system because the compiled application is available with
the key. This would stop amateur hackers, but not persistent,
experienced hackers.

What about all you developers out there?  How do you make sure that
web server requests were properly generated from your android
application? Or do you just assume it will be OK and that no one has
time to try to break your cell phone app? Is there a better system I'm
not thinking of?

[android-developers] How to create Add On Packages

2009-10-23 Thread Warren


I have seen several applications that are free, but allow for add on
packages to be installed.

Gang Wars sells Respect Points
Mafia sells Favors
Dungeon Quest sells Gems

The central game is a free app, but you purchase these add on apps for
in-game benefit.

Has anyone purchased one of these add on apps?  What is the experience
like?  Do you have to leave the add on installed on your phone?

How does this work technically?  Do you think they set shared
preferences?  How would you handle the 24 hour uninstall rule?



I am considering releasing a free game with 10 levels, but offering a
full set of levels (say 25) as a separate paid app.  I'm looking for
the best way to accomplish this and thought the above might have some
bearing.

Thanks for your time,
Warren

[android-developers] Can You Query Package Manager Star Rating Information

[android-developers] WVGA800 and WVGA854 for games

2009-10-02 Thread Warren


I have developed a game for android that really needs to have a
480x320 resolution.  I have considered trying to alter the game to
work with different resolutions, but this would be very difficult if
even feasible. I know of at least one phone from Motorola that will
have a WVGA screen. I loaded my game in the new 1.6 emulator with a
WVGA screen and the game was scaled up to fill the screen with a black
bar of unfilled space on the right.

I'm happy to see that the application scaled up, but I wish it didn't
have a black bar on the side. I am also anxious to see how the scaling
performs. My game needs every bit of CPU it can get.

I assume others of you have apps that rely on 320x480 screens. They
might rely on them for a reason, like mine, or it may be that you
haven't gotten around to designing for multiple screens yet.  At any
rate, how do you plan to deal with other screen sizes? (There are QVGA
phones coming soon too.)  I'm trying to decide the best way forward.

Thanks,
Warren

[android-developers] Re: ADC2: Low volume of judges

2009-09-28 Thread Warren


It's true that some apps will be rated lower because they don't apply
to the user doing the judging. For instance I judged an app that was
designed specifically for users in Paris. It was low for me on the
indispensability scale as it would be for most people not in Paris.

BUT if it is clear from the outset that the app does not apply to you,
then you might skip it. This could lead to higher concentration of
judges who say, Ahh, an app that serves my niche! actually scoring
the app. For instance, an app named, Find the Closest Bathroom in
Paris would probably be skipped quite a bit by people not in Paris.
You might end up with 75% of the judges for that app actually being
from Paris. But if the app is called Bathroom Finder and gives no
hint that it is geographically limited, you'd get no such effect.

 Who knows? This is all just conjecture and guessing.  The effects
might balance each other out. They might not. There won't be a clear
picture until Google releases some results... maybe not even then.

 I don't really agree with the MY needs line personally. We are
 acting as judges - and therefore should also take into consideration
 how an application would be useful to others. For example, I
 personally dislike most social networking applications, and do not
 even bother to use twitter or facebook outside of Android. Rating most
 social network application badly and giving them 1s in
 indispensability due to my personal preference would not be right, in
 my opinion. Of course, I do skip most of those related to this
 category, just saying I think there might sometimes be more to it than
 what does this app do for me.

A Cartoon Styled Turn based Artillery Game

ADC2 Feedback: Making a fast game on a phone running a virtual machine

I did not find the August 1st constraint to be a problem. I am

when the deadline came, I submitted what I had, fully intending to
continue developing.

There is a sense of relief when you submit your game... followed by a
mild sense of panic: Did I submit it correctly? Did I get the right
file?  Did I forget anything?

I am expecting stiff competition. But the whole process is enjoyable.
It's great to hear from people who enjoy the application you wrote.
Stiff competition means better apps for our phones. And we all want

[android-developers] SurfaceDestroyed and Game Thread Problem

2009-07-19 Thread Warren


I am having trouble with the order of function callbacks in a game. I
create and start a game thread in the onCreate() of my activity.  In
the onPause() of the activity, I pause the thread. And in
surfaceDestroyed() I stop the thread entirely. I have tried several
other configurations, but I always run into one of two scenarios: I
either try to start a thread that already exists, or my activity
resumes without restarting the game thread.

I'm wondering if there is a best practice or accepted way to start,
pause, and resume the game thread.

Has anyone else had a similar problem. How did you resolve it?

[android-developers] Re: Black Screen problem with graphics update using unlockCanvasAndPost()

2009-04-15 Thread Warren


Thanks for the comment ellipsoidmobile.

If I remove the sleep, I still don't see anything until the very end.
I don't need that sleep in there for the application. I only put it in
so that, hopefully, I could see what was happening a little better.

Also, I thought that the SurfaceView allowed you to write to the
screen at your own pace, whatever that may be. So in this case, there
would be nothing from the outside that's causing a screen refresh.
The screen should stay how I left it until I post a new canvas. Am I
misunderstanding this?

What really confuses me is why the last call to unlockCanvasAndPost()
does work.  It seems like if an error prevented the first calls from
functioning, then it would also prevent the last.

 I believe with SurfaceView you have to draw your whole view on 
 everyscreenrefresh. You just need to loop as fast as possible and the
 system will throttle the speed in the calls to lockCanvas(). By
 sleeping for 1 second you are failing to provide a canvas for every
 refresh so thescreenappears blank.

 What I don't know is whether there is any guidance on how quickly you
 have to get through your loop, i.e. what the maximum refresh rate is

[android-developers] Re: Black Screen problem with graphics update using unlockCanvasAndPost()

2009-04-15 Thread Warren


I may have found my problem.

The SurfaceView class implements a function called draw(Canvas).

I unwittingly created my own function draw() with the same signature,
overriding the original. I'm guessing that the SurfaceView probably
calls draw() during unlockCanvasAndPost(). But instead of executing
its original draw() method and doing what it is supposed to do, it
calls my function - simply overwriting the canvas buffer without
affecting the Surface at all... thus the black screen.  I'm still
confused about why it eventually shows. Perhaps some final cleanup
code...

I will test this tonight when I have access to my development computer
and post my findings.

2009-04-15 Thread Warren


Sarnoth, I appreciate you taking the time to comment.


Does that matter - if the thread isn't different?

Just in case there were problems with the thread, I rewrote the
program not to use a second thread and just execute the drawing loop
in the view.


In the code sample, I also changed draw() to drawSprites(), as I
described in an earlier post. Neither of these things helped.



== Begin Code ==

package com.baltz.scorched;

import android.content.Context;
import android.content.res.Resources;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.util.AttributeSet;
import android.util.Log;
import android.view.SurfaceHolder;
import android.view.SurfaceView;



class ScorchedView extends SurfaceView implements
SurfaceHolder.Callback {

private Context context;
private SurfaceHolder holder;

private Bitmap backgroundImage;

public ScorchedView(Context c, AttributeSet attrs) {
super(c, attrs);
// register our interest in hearing about changes to our
surface
holder = getHolder();
holder.addCallback(this);

context = c;

resources = context.getResources();


// load background image as a Bitmap instead of a Dable b/c
// we don't need to transform it and it's faster to d this way
backgroundImage = BitmapFactory.decodeResource(resources,
R.drawable.earthrise);

foregroundImage = BitmapFactory.decodeResource(resources,
R.drawable.foreground1);

spriteImage = BitmapFactory.decodeResource(resources,
R.drawable.sprite1);

terrain = new ScorchedTerrain(foregroundImage);

engine = new Engine();
Body body;

body = new Body(spriteImage);
body.setLocation(50, 50);
engine.addBody(body);

body = new Body(spriteImage);
body.setLocation(40, 100);
engine.addBody(body);
}

holder = h;
}

holder = h;
gameLoop();
}

 I can't really say without seeing more of the code, but based on your
 description of the problem I wonder if your thread is in fact a
 separate thread or if the run method is simply being executed in the
 main UI thread. Something worth checking. You can log
 Thread.currentThread().getName() from inside your run method and from
 inside your activity's onCreate method to make sure they are
 different.

[android-developers] Black Screen problem with graphics update using unlockCanvasAndPost()

2009-04-14 Thread Warren


I am working on a game for Android. I'm following the general program
layout of Lunar Lander, where a SurfaceView has a worker thread that
runs the main game loop. That loop updates the physics and redraws the
screen by creating and drawing to a canvas.

From the thread class:

public void run() {
int i = 0;
while (i  10) {
Canvas canvas = null;
try {
canvas = surfaceHolder.lockCanvas(null);
synchronized (surfaceHolder) {
engine.update(); //physics calculations
draw(canvas); //draw various bitmaps to the
supplied canvas
}
} finally {
// do this in a finally so that if an exception is
thrown
// during the above, we don't leave the Surface in an
// inconsistent state
if (canvas != null) {
Log.w(dbg, unlocking and posting canvas  + i);
surfaceHolder.unlockCanvasAndPost(canvas);
}
}
i++;

//delay for a second so I can see what's happening
try{
  Thread.currentThread().sleep(1000);//sleep for 1000 ms
}
catch(Exception e){
}

}
}




I believe
surfaceHolder.unlockCanvasAndPost(canvas);
is supposed to release the canvas and force the screen to redraw
correct? That's not what I'm seeing. I'm getting strange behavior
where the final draw works, but each previous draw only shows a black
screen.

For a better example, I draw a small character sprite at the left side
of the screen. Then, for each successive frame of 100 frames I
translate the image one to the right. So I expect to see the sprite
slide to the right as the program runs. Instead, the screen is black
the whole time until the end, when the sprite appears already on the
right side of the screen. It's as if the very last call to
unlockCanvasAndPost() is applied to the screen, but the others are
hidden or not drawn.  I've verified that they are, in deed, being
executed.

Any help would be appreciated.
Thank you.
