Your reply, TreKing, reminds me of the classic joke: you ask a programmer 
if he knows what time it is, and he says 'yes';)

But a little more of a hint would have been quite appropriate. I take an 
especial interest in this because if I had been the one designing the 
Android database API, I like to think I would have made it a lot easier for 
the client programmer to use the exact same sequence (after initialization) 
of API calls whether the database is located on the phone or remotely 
accessible via (for example) HTTP. But they did not do this, and it it 
really not obvious how  best to approach the problem.

Even many of the people answering the same question on StackOverflow admit 
there is no one, good solution to this problem, saying instead 
disappointing generalities such as There is no easy way of connecting 
Android DIRECTLY to a remote database. No wonder all the answers got such 
low ratings!

Re: [android-developers] Re: What is the best phone to buy for Android Development?

It is true, but misleading that the emulator may work for most cases. 
Unless you are doing a very simple app, you should not even think of 
uploading it to the market until you have tested it on a real phone, 
preferably unrooted, since that is what most users will use. It is 
imperative if you are using OpenGL, the video, camera or sensors.

This is because there really are different bugs in each of these areas not 
only on different phones, but even different software releases for each 
phone. This is the infamous fragmentation Google loves to pretend does 
not exist. But it is real, and that keeps companies like DeviceAnywhere in 
business, since they can test your software on a staggering variety of 
phones.

[android-developers] Re: What is the best phone to buy for Android Development?

Everything you cay about command line vs. Eclipse window could be true yet 
there would still be one overwhelming advantage for the command line: the 
Eclipse UI and documentation for how to do all this filtering is limited 
and put in odd places; it is much easier to find out how to use 
command-line redirection and grep on command-line output, and those are 
both well documented. The documentation is easy to find, too.

Also, when the Eclipse window simply fails to display the logcat output, I 
can never figure out why (except for one case: when 'Device' got 
mysteriously de-selected, which should never happen but does happen). When 
the command-line fails to display it, I can easily figure out why.

 As you say, the volume of output can be excessive, but if so, it's the

 I don't believe the steps to filter output and adjust buffer sizes can be 
 considered time wasting. Time 
 is wasted if it produces less value than it costs. These steps produce 
 more value than they cost.

 While I normally use only command line myself, I find the Eclipse logcat 
 window to be very flexible. It has all
 sorts of convenient tools to help you filter your messages, so if anything 
 folks would find it easier to use
 than command line, contrary to your conclusions. It lets you dynamically 
 filter on debug level, process id (pid), 
 regexes, app, tag or specific text. AFAICT it's infinite, so buffer size 
 is a non-issue, and it has buttons 
 to save the output and manage your filters.

 YMMV, but I don't recommend scaring people off the Eclipse logcat window.

[android-developers] Re: abstract Uri?

You question the 'naturalness' of his desire to use 'new', but you don't 
seem to notice: you have merely moved the question, not answered it. Of 
course it is 'unnatural' to call 'new' on an abstract class, but he was 
asking why it was made abstract in the first place. You did not address 
this. Nor does the Google documentation of the class.

All you did was move the question to why is calling a factory method more 
'natural'? After all, factory methods are for when you do NOT know ahead 
of time exactly which class the created method will be. But why would that 
be the case here? THAT is what needs to be explained.

Nor is it clear why you think there should be no obvious implementors of a 
class named 'Uri'. One obvious implementation of a class with such a name 
would be 1) Constructor takes string, returns (opaque?) integer handle for 
uri 2) methods for opening, closing, fetching resource at uri given by 
handle. But this is not the way Google did it; the Uri class instead has a 
noticeably more restricted scope. It does not provide methods for opening a 
Uri and fetching resources. Instead, the main methods provided are for 
analyzing the Uri string itself, breaking it down into port, authority (if 
any), query string etc. Other objects are then responsible for fetching.

What benefit they got from doing it this way is far from clear, especially 
since they are now recommending use of java.net for external HTTP access 
for recent versions of Java, using android.net mainly for the internal Uris 
used for Content Providers.

As for using the Wikipedia entry, I have been often disappointed by 
Wikipedia entries on OOD topics before. This time also, since they put the 
reader through an alleged Java example of the Factory method (complex 
numbers), and then admit that strictly speaking, it is not even an example 
of the pattern. This is NO help to the learner, and little help to the 
seasoned programmer.

Finally, it is ironic that you observe (correct though that is), that use 
of factory methods is prevalent throughout the Java API. For java.net.URI 
is NOT abstract, but android.net.Uri IS abstract. The similarity of these 
names is probably a large part of why the OP expected both to be concrete. 
Both claim, after all, to do roughly the same thing: represent a URI (one 
immutable, the other mutable). The differences in the API alone do not 
really explain why they made it abstract.


bob wrote:

 Can someone help me understand why the android.net.Uri class is abstract?


 You got the what, now for the why.
  

 Naturally, I want to do something like this:

 I question the naturalness of that desire.
  

 Uri uri = new Uri(http://www.example.com/file.mp4;);


 It's more natural, some would say, to use a factory method. (Google Java 
 factory method 
 and you'll find, e.g., 
 http://en.wikipedia.org/wiki/Factory_method_pattern#Java, complete 
 with reference to Josh Bloch's advice on the matter.)

 It's entirely unnatural to want to call a constructor on an abstract 
 class. Such a class with 
 no obvious implementors is a signal that it has a factory method. This is 
 quite prevalent 
 in the Java API.

 The why is to save the client from messy and irrelevant details of the 
 implementation.
 You shouldn't have to decide which particular flavor of 'Uri' to 
 instantiate, especially if the 
 thing is tricky (e.g., has to support an ever-expanding list of 
 protocols). Let the factory 
 manufacture you one and you save all that headache.

 Study up on the reasons to prefer a factory method, and when not to.

[android-developers] Re: What is the best phone to buy for Android Development?

2012-10-03 Thread Indicator Veritatis

Yes, testing on real devices is important and useful for all the reasons 
you gave. But there are others. For one, it takes a ridiculously long time 
to launch the emulator. Hook up a real phone via USB instead, and it is 
ready in under 10 seconds. Another: the permissions are different on a real 
phone and the emulator. You automatically have root permissions on the 
emulator. Not so on the phone. This means that if you want to test the 
software in the environment the user will see (and you really should want 
this), you get a much closer match by using a real phone.

So summarizing briefly, yes, you can do a lot of useful testing on an 
emulator, and it is a cheap and easy way to test on various screen sizes. 
But before you release your product to the market, it must be tested on a 
real phone, and should be tested on as many as possible.

 Main reason is that the Google phones allow you to see your own debug

 such junk debug messages on the console, that they swamp your own debug

 I assume that by debug messages you mean the logcat contents. You can 
 filter those by command-line

 the buffer size to capture more data, or run the adb logcat command in

 If you can live without relying on debug messages through Eclipse then 
 any good  recent phone will likely do, eg Samsung Galaxy S3, HTC One X,

 The Google phones get OS updates before other phones as well.

Good assumption, even if it turns out not to be true in this case. I would

Why the FBI would need that much detailed information for the stated

the developer responsible for uploading to the alternative market is the 
same as the one uploading on Google. They do not need the developer's full

[android-developers] Re: Getting started with Android. Love the overall system architecture and SDK except for one thing...

2012-08-21 Thread Indicator Veritatis

Google's approach to documentation has its frustrating points, and to be
sure, finding the right XML name for the concept/class/value you find in
the API documentation has always been a frustrating experience. But it
should not be THAT frustrating.

Also, some of the gaps in concept presentation you complain about in the
online docs and tutorials are better addressed by the better books on
Android. My favorite has long been the Manning Press Unlocking Android
(with slightly different names in different editions), but there are other
good books, too. Mark Murphy's is quite good too, as is anything by Reto
Meier.

If you are reluctant to spend $40 or more on a book you are not sure is the
right one for your needs, Safari Bookshelf now offers many of them through
your local public library. And Murphy's in older editions (dated, but still
valuable) are available for free download.

For that matter, if you have the patience to read undocumented code, most
of these books have the code downloadable for free. You do not have to buy
the book to find and download the code. But of course, the code is
explained only in the text, with very sparse comments in the code itself.

The suggestion about ApiDemo is also good, but those tend to demonstrate
only the very basic elements of how to use the APIs, they leave out a lot
of details only some of which are in the API documents. Not so long ago,
people answered questions about such details in all seriousness with read
the source code:(

But really: how is all this any worse than in iOS? When I did a small iOS
project, I had to learn iOS from scratch. At first, I was in awe of how the
iOS documentation covered important aspects Google had left out of Android,
but when I actually started trying to apply what I learned there, I found
out that they too left out a lot of important info. A typical problem I
found, for example, was that Apple still offers as their most uptodate
sample code, code that was written under the 3.2 version of Xcode, using
old APIs no longer recommended, workarounds no longer needed and not even
using storyboards. Sure, you can let Xcode convert it to a 4.1 project, but
then what are you learning from the sample code? Certainly not how to
design the connections between storyboard and callbacks.

So at this point in time, I am convinced that Apple's support of iOS and
Google's of Android are about equally frustrating. It is just that the
particular problems are different, such as not having to wait for approval
before your app goes on the market in Android, but facing arbitrary delays
with Apple.

4. After much trial, frustration and anger finally retreat to something
else.

I'll give an example of such a feature: Horizontal view swiping. From the
official Android Play store to the CNN App, this is probably the most

[android-developers] Re: how to get reference to GLSurfaceView's rendering thread?

2012-08-06 Thread Indicator Veritatis

Well, I may have overstated my case: it is not THAT bad, like stop() or 
suspend(), which fully deserve their deprecation, since they are so broken. 
But neither is it that good. If you are using it a lot, it is a strong 
hint, though not a proof, that you are going about something the wrong way. 
For when following the safe-threading practices well established in the 
industry since Birrell, synchronization uses locks/monitors instead of 
directly affecting the scheduler as join() does.

However, the prohibition is not absolute, like the prohibition against 
stop(), destroy() or suspend(), which are officially deprecated, and have 
been for a long time. It is more like a warning that you are probably 
following the wrong idiom, since its best uses are so rare.
 
Code using join() to do synchronization may indeed work. If all your other 
threads really do refrain from accessing state in the waiting thread and 
you have verified with a wait-for-graph that deadlock is impossible, you 
are most likely quite safe -- until somebody modifies your code forgetting 
what made it safe.

However, Birrell included join() in Topaz but then said it was rarely used, 
Berg described it as used very rarely, and as I already mentioned Goetz 
gave only one example of a concurrency pattern using it.

Finally, there was a very good talk last week at the SF Android Meetup 
given by O'Reilly author Blake Meike on concurrency in Android: his basic 
thesis was that concurrent coding should use as first choice AsyncTask, as 
second choice, Looper/Handler; only when these fail to provide what is 
needed should one even resort to Java's new java.util.concurrent classes. 
Only when truly desperate should one consider going to even lower level 
code, such as Java 1.2 support for concurrency, including join().

Now of course he realizes (as do I) that there are exceptions, when you 
really do need to resort to java 1.2 support bypassing even such handy 
goodies as Executors and concurrent collections (e.g. BlockingQueue). But 
they are not common. Bugs in multithreading code are much more common, 
especially when low level code is used too often.

2012-08-03 Thread Indicator Veritatis

Of my two favorite books on concurrency in Java, one recommends never using 
join() in the first place, the other uses it only for a poison-pill in an 
implementation of producer-consumer when you know you want to shut it down 
if the queue ever empties completely.

Now I realize it is not very helpful to say don't do that without 
offering a better alternative, but I see from the other responses that this 
is not a simple problem. The best I can do to help is say 1) as above, 
don't use 'join()', which is so rarely the right tool 2) don't wait until 
onDrawFrame() is called to load libraries. That is much too late in the

 I'd like to call join() on it to make sure the thread has exited. 

 (Broader context for those interested: I have a crash in my GL-based

 - device is put to sleep with my app in the foreground 
 - an incoming call wakes the device up 
 - I receive onResume() and I call onResume() on my GLSurfaceView 
 - I receive onPause() almost immediately after onResume() since the 
 phone app goes to the background due to the incoming call 
 - the time between onResume() and onPause() is rather short but enough 
 for GLSurfaceView to go through all of its setup up to and including 
 the initial onDrawFrame() call 
 - my onDrawFrame() goes into texture  geometry loading routine which 
 can take up to several seconds so it's still loading when onPause() is 
 called as mentioned previously 
 - like many people here I have a globally-accessible method of 
 retrieving a reference to my main Activity to be used as the current 
 Context.  This is used while loading graphics data to read asset 
 files. 
 - this Context reference however gets nulled out in onPause() in an 
 attempt not to leak main Activity instances.  As the main thread 
 running onPause() nulls it while the rendering thread is still needing 
 it to finish loading the program crashes. 

 The idea is to call GLSurfaceView.onPause() and then wait until the 
 rendering thread actually exit.  Then null the Context reference.)

[android-developers] Re: adb devices is showing the device as offline.what is reason? How can i switch the device from online - offline viceversa?

2012-07-23 Thread Indicator Veritatis

You are right to be skeptical of the answers already give you. Clearly, adb 
is running. But what is not clear is whether or not adb has already got 
itself into a confused state.

Although I have not had the exact same problem you report, I have been able 
to address similar problems by stopping and then restarting the adb server: 
that is what I do when I know the device is there, but adb devices does not 
report it. And although I cannot think of why it would make a difference, 
it seems to work more reliably if I do this as superuser (on my development 
system, which runs Linux) than if I do it as a regular user.

Of course, that is not much help to you if you have to run a monkey over 
night. But it might at least help you narrow down what the problem is.

 Hi

 I connected My android ICS device to my windows PC using USB.

 I executed adb devices from my pc.

 List of devices attached

 After a long time of say 12 hours, i ran the same command adb devices 
 from my pc.

 The output
 ---
 List of devices attached
 id   offline

 I am not sure what went wrong. i did not even touch my pc, and my device.
 I made settings in my PC so that it will never sleep.
 I am running monkey scripts which wont make android device to lock as well.

 Many people said that ur device is offline because adbd deamon is not 
 running on android device. 
 But this is wrong, why because if adbd is not running then the device will 
 not be listed at all.


 I came across adbd deamon process which will be running on my android 
 device.
 For my device to get detected by adb(server on my pc)  adbd must be 
 running.

 I went to adb shell
 I stopped adbd using the command stop adbd
 This stopped my adbd deamon on android device.because adbd is stopped mt 
 adb(server on my pc will not detect my device)
 Now adbd is not running, I execute the adb devices command the output 
 is, list of devices with empty list.
 The output
 ---
 List of devices attached
 ---

 because the device it self is not detected i cannot log in to adb shell 
 again to start adbd  adbd deamon on my device.
 so I shutdown and rebooted my android device, this made my adbd deamon to 
 run again.

 Now when i executed adb devices on my PC
 The output
 ---
 List of devices attached
 id   device
 ---


 By seeing this output it is very clear that adbd deamon is running on 
 device, because if adbd is not running then the device will not be listed 
 at all.

 Now the question is?
 what is the reason for the device to go to offline? (i am very sure that 
 adbd deamon not running  is not at all a reason for this.)
 How can i switch the device from online - offline viceversa?

 I am very very thank full to any android expert who solve my confusion.

Re: [android-developers] which is best Handler or Timer ?

2012-03-24 Thread Indicator Veritatis

This answer is true and correct, but could have used a little more 
explanation. The Timer class is included because it is expected in Java. 
But it is not particularly suitable for the way tasks and processes should 
be handled on an Android phone. Handler is. The OP can define an arbitrary 
message and get the effect of a timer by posting the message to the 
pre-existing queue with sendMessageDelayed(arbitraryMessage, 
timerInterval). Or if more convenient, instead of a message, put the 
Runnable you want executed on the queue with postDelayed(Runnable). The 
choice of which is best depends on your application's individual 
circumstances, but I prefer the message approach, unless doing a splash 
screen (for which see 
http://stackoverflow.com/questions/5486789/how-do-i-make-a-splash-screen-in-android).

Now for 'suitable', what I mean is: if you (the OP) use the Message 
approach, you do not have to define your own thread for the Timer, so you 
sidestep all the issues of thread management, letting the system handle it. 

See the class reference for Handler for details.

[android-developers] Re: How to keep activity running

2012-03-19 Thread Indicator Veritatis

I see the thread has progressed quite a bit from this original question, 
but I still feel the need to answer this original question clearly: you 
should certainly not override the onDestroy. If it gets called the need 
for you to release resources is genuine, you should just do it.

Others have already mentioned using Service, this is certainly going to 
play a major part in your final solution, however you decide to factor your 
business logic between the Service and the Activity (or Activities). 
Providing a place in the background for things to go on for a long time 
even when the Activity goes away is the major purpose of having a Service.

[android-developers] Re: draw texture in OpenGL Android from 0,0 coordinates

2012-03-03 Thread Indicator Veritatis

Use absolute screen coordinates in OpenGL? That defeats the purpose of 
much of OpenGL. The reason it takes you from world coordinates to object 
coordinates to camera coordinates to clip coordinates to device coordinates 
is (among other things) so that you never DO need to know the device 
(absolute screen) coordinates.

Yes, all those coordinate transforms can be quite confusing, especially for 
a beginner, but please understand that they are there for good reasons 
instead of trying to bypass them all.

http://www.opengl.org/resources/faq/technical/transformations.htm#tran0001 
is one of the better explanations on the web of all these transformations.

The post by Dark Photon at

2012-02-27 Thread Indicator Veritatis

As you say, this structure is kind of messy, and even the name for
it may strike you as a little 'messy';) It is called an anonymous
class. You might want to look it up in the classic online tutorials
originally created by Sun and now maintained by Oracle.

I found it messy too, and I still find the standard indentation of the
anonymous class annoying. But I decided to learn to live with it
because 1) it is extremely common, and that not just in Android Java
2) there is one big, good thing it does for us: it spares the reader
from having to track down all references to the class to verify that
it really is instantiated only in that one place. This really does
simplify debugging. It also explains why it is heavily used in Swing
and JavaFX as well as Android.

In fact, that is pretty much what the above-mentioned tutorials says
at 
http://docs.oracle.com/javase/tutorial/uiswing/events/generalrules.html#innerClasses.

 the function, public void onItemClick be by itself, so that I can do
 something more along the lines of: (psudo code)
 gridview.setOnItemClickListener([somehow reference the function
 here]);

 Is what I'm asking possible?
 Does my question make sense?
 Is there a more appropriate group to ask this kind of question?

Correction: they are line numbers, just not in YOUR code: e.g., 461 is
a line number in AdapterView.java, which doesn't help much. As for
your original logcat listing, what you need to do here is notice that
this is a Runtime exception thrown because you don't have a method for
addView(View, LayoutParams) in the view you added, AdapterView.

And indeed, if you look at the up to date javadoc for AdapterView, you
will find that it throws an exception for most combination of addView,
in particular, for the one you tried to do. AdapterViews are not
supposed to get their views this way.

So the REAL question is: why are you trying to call addView on an
AdapterView?

 He's not, the framework is -- since the ListView in the XML has children
 (and one of those is another ListView, oh my).

That is by far the best proof. Get an app on the Android Market. Even
getting it up on one of its far less well known competitors is good,
but the Android Market is so much better known, you may as well start
there.

[android-developers] Re: Logcat is broken every time phone is unplugged

2012-01-27 Thread Indicator Veritatis

Although I dont' remember encountering exaclty the same problem, the
unreliability of logcat display from inside Eclipse is the reason I
long ago got into the habit of runnig logcat in a Terminal window (I
run Eclipse under Linux, not Windows) instead. But even then, when I
disconnect the USB cable for the phone, I find that often I have to
restart adb. But this is a lot less drastic than restarting Eclipse.

So that is what I suggest you try: stop and restart the server using
the adb command from a terminal window (or a command shell) when you
see that problem. It is a lot faster than restarting Eclipse.

On Jan 14, 12:24 pm, Keith Wiley kbwi...@gmail.com wrote:
 Every time the phone is unplugged from USB, the logcat is permanently
 corrupted in that the when the phone is reconnected, logcat does not
 reestablish.  Restarting an app, either in debug or run mode produces
 zero logcat output after that point.  Closing the logcat window view
 and reopening it has no effect.  The only solution is to quit and
 restart Eclipse.  Therefore, I must quit and restart Eclipse every
 time I take my phone with me and then later return.

 I've been having this problem since day one with Android development,
 three years ago.  In that time I have installed new versions of
 Eclipse and numerous updates to the Android SDK and Eclipse plugin.
 Nothing has ever improved the situation w.r.t. this bug.

 Anyone know anything about this?

[android-developers] Re: MVC Architecture

2012-01-14 Thread Indicator Veritatis

Why? Because the Wikipedia entry on the topic just is not that good.
In fact, MOST of the sites that show up in a Google search for MVC are
just not that good.

The only sites I found on the topic that are good are: 1) apple
developer sites on it and 2) IBM developer works. (in the developer
works search field, enter model view controller java). 3) Ward
Cunningham's Wiki on Patterns: http://c2.com/cgi-bin/wiki?ModelViewController

So I suggest instead of just Googling mvc or model view controller
he should narrow things down to the good stuff with apple developer
mvc. The article in Cocoa Design Patterns is particularly good,
though several others are also well worth reading.

Everything I have read in the Apple Developer Library concerning MVC
is quite applicable to Android -- and MUCH better written than
anything in the Android documentation. Let me repeat that: MUCH better
written.

Once you have read a few of these sites, you will understand the
pitfalls of the point of view that In most cases, I think, you are a
mere user of MVC implemented by
Android SDK. If you are a naive user of the SDK classes, and are not
very aware of what the MVC pattern is, then you will make mistakes in
applying it despite the design of the classes, and you will NOT
benefit from the 'pattern-ness' of the MVC pattern.

A classic example of how to fail to benefit from the pattern-ness is
shown in Lecture 1.pdf of Stanford University's CS193 course on iPhone
programming, which shows both how to do it and how NOT to do it. It is
available from iTunes University, free. Again: everything in that
lecture concerning MVC is just as applicable to the Android SDK. Even
the name changes are slight.

On Jan 13, 1:41 am, Daniel Drozdzewski daniel.drozdzew...@gmail.com
wrote:
 I am with TreKing on this one.

 The question is very vague. Does Sree want to know about MVC in
 general? His question certainly looks so.
 If so, then it's hardly Android SDK, and Wikipedia has an entry for
 it, so why wasting people time and bandwidth.

 This list seems to have a lot of noise like that (victim of Android's
 success) and one receives around 50 posts every hour, out of which
 maybe 3 are relevant, well formed and interesting.

 If it is about MVC in Android, then it is still quite generic and
 speculative, but interesting.

 I don't think that you implement MVC as such as long as you use
 Activity and View objects. You could, when taking full controll of the
 screen, like in a game with your custom UI.

 In most cases, I think, you are a mere user of MVC implemented by
 Android SDK. Activity hosts Views so it is a View + Controller, but
 can easily hold Model objects too, in case when model is small. Model
 could also be implemented separately by a Service or Content Provider.

  Ok, nice first answer.
  The question is not stupid, because an Activity mix life cycle and

  activity manage lifeCycle and delegate GUI to your GUI package. In

  separation (Model, View, BuisnessService, Service  (i mean android
  service), DAO (that contains usual DAO and your Content providers) and
  you also have the Communication layer and the transversal one), as

[android-developers] Re: how to convert morse sound to text???

2012-01-12 Thread Indicator Veritatis

It would if there were an Android API for it. I am not aware of one,
and I doubt one exists. This is rather a fairly simple (audio) signal
processing task.

What does have to do with Android is the question: how can he use the
phone's microphone to listen to the sound, what APIs should he use to
generate an audio stream out of it (for that signal processing)? The
answer to these questions is not obvious either.

Do you have to use 8 bits for each of RGB? Surfaces and textures on

 Hi,

 I am experience flicker in the visuals, which after some

 I've found this old thread on this

 I can see the flicker happening, even with absence of any touch

 Visuals that are overdrawn later in the frame are briefly visible none

 The only way I can explain this behaviour is that the drawing occurs
 in the front buffer.

 Some details on my code:
 - I use OpenGL ES2
 - NDK r7
 - Device: Acer Iconia Tablet running Android2.3
 - Using NativeActivity, with all-C code, no java code
 - Using this spec for choosing GL config:

             EGL_SURFACE_TYPE, EGL_WINDOW_BIT,

             EGL_RED_SIZE, 8,
             EGL_ALPHA_SIZE, 8,
             EGL_NONE
     };
 - Only do glClear(), one glDrawArray with LINES, and one glDrawArray
 with TRIANGLES per frame.
 - Use eglSwapBuffers() at the end of my engine draw func.

 Any tips on how I could fix this?

2011-12-27 Thread Indicator Veritatis

I'll take your word on that one, since I haven't had time to look at
at that thoroughly myself yet; but I do know that a genuine must
read is The Orange Book, which is downloadable in an earlier edition
from 
http://wiki.labomedia.org/images/1/10/Orange_Book_-_OpenGL_Shading_Language_2nd_Edition.pdf
or you can buy the latest from Amazon.

This book has the best explanation I have ever seen of the
programmable pipeline in OpenGL 2.0. Unfortunately, it is all about
OpenGL rather than OpenGL ES, but such is true of most of the
reference this thread has shown to date. Then again, the basic
concepts are best explained in books like this one, then you can rely
on the difference specification from Khronos to learn to apply it to
OpenGL ES.

 Hi all.

 I have an app and fixing errors/bugs. But I have problem when
 NewPictureNote.java calls PhotoTaker.java using
 startActivityForResult() to take a photo and save. My code uses
 callback and put binary data into Intent to return to previous
 activity. Here is the code:

 //PhotoTaker.java
 public class PhotoTaker extends BetterDefaultActivity implements
 SurfaceHolder.Callback{

 //..

    public void clickHandler(view v){
         //.
         Intent returningIntent = new Intent();
         returningIntent.putExtra(EXTRA_IMAGE_DATA, jpegPictureData);
         setResult(RESULT_OK,returningIntent);
         finish();
         break;
     }

 }

 //NewPictureNote.java
 public class NewPictureNote extends BetterDefaultActivity {
 //

 protected void onActivityResult(int requestCode, int resultCode,
 Intent data) {
         super.onActivityResult(requestCode, resultCode, data);

 try
         {
             //If we are getting a response from our picture taking activity
             if(requestCode ==REQUEST_CODE_TAKE_IMAGE)
             {
                 //If it was successful
                 if(resultCode == Activity.RESULT_OK)
                 {
                     //do something
                 }
                 else
                 {
                     //The user cancelled or an error occured
                     setResult(Activity.RESULT_CANCELED);
                     finish();
                 }
             } else {
                               //...
             }
         }
         catch (Throwable e) {
                       //...
         }

 }

 When I debug code, clickHandler() method in  PhotoTaker.java works
 well. It calls till the end of the clickHanlder() but the Activity
 won't close and onActivityResult() does not work. Please let me know
 what problem is? Thanks in advance.

[android-developers] Re: Connecting to a server on a LAN

2011-12-06 Thread Indicator Veritatis

How else would you want to connect? There is no Ethernet connector on
most Android phones. So your only other option would be some non-
standard kludge using USB as your Layer 0.

After all: your 3G or 4G connection is outside the LAN.

[android-developers] Re: URGENT HELP : Bypassing Default Camera Viewfinder

2011-11-18 Thread Indicator Veritatis

I gave you an answer for doing something fairly close to what you are
trying to do, but not identical. But now it seems that for whatever
reason, you are determined to go beyond that to take over the Camera
object's SurfaceView. That is not supported by the framework, nor is
it clear that it should be. What is so wrong with letting the Camera
object do its job?

 Hi Veritatis.
 I completely agree with you on the formatting part (I have the byte array
 which I can convert into any format and I am doing it via bitmap only)

 Here is the code :

 //initializing the compression and Byte Stream Part

 ByteArrayOutputStream bs = new ByteArrayOutputStream();
 YuvImage yuv_image = new YuvImage(*buffer1*,20 , 640, 480, null);

 // Doing the Compression part

 Rect rect = new Rect(0, 0, 640, 480);
 yuv_image.compressToJpeg(rect, 70, bs);

 //Finalzing the image writing part as JPEG

 outStream = new FileOutputStream(String.format(/my/image/location));
 outStream.write(bs.toByteArray());

  jpgView= (ImageView)findViewById(R.id.jpgview1);

 //Bitmap Part

  BitmapFactory.Options options = new BitmapFactory.Options();
  options.inSampleSize = 1;
   Bitmap bm = BitmapFactory.decodeFile(/my/image/location);
   bm =
 BitmapFactory.decodeByteArray(baos.toByteArray(),0,bs.toByteArray().length);

 *bs is of type -- ByteArrayOutputStream
 and jpgView -- ImageView*

 If I supply the continous frames buffer1 to I YuvImage will be able to see
 the video on the ImageView.

 So now instead of previewing it on Imageview I wanted to Utilize the
 existing camera Viewfinder(Surface Holder- Surface-Jsurface..) to preview
 image and videos but to do that I dont know whether I have to tweak
 Framework/base/* camera files or that can be done on the Application level
 only(the android application - and not Application framework)

 One neat hack will be to preview everything on some media player(not via
 using android media framework - that can be but not sure wether it will fit
 as it is tagged with the camera internally)so that it will give the user
 the impression that the viewfinder is turned ON though the media player
 will be ON displaying the continous frames and not the Camera Viewfinder.

 PS : Title of this post is about giving the frames(Dummy as for now) to the
 Camera ViewFinder.Just a summary :) !

 What continuous jpeg frames? The only 'continuous' frames in the
 viewfinder are the preview frames, and those are not jpeg: they are
 YCrCb at 15 fps. Unless you make your own jpeg out of YCrBb, but why
 bother? You need a Bitmap for the Canvas for SurfaceView anyway: you
 may as well use RGB or ARGB instead of JPEG (see Bitmap.Config). Then
 no conversion is necessary. In fact, it is not useful with a Canvas,
 since it is not among the formats listed on Bitmap.Config.

2011-10-28 Thread Indicator Veritatis

If you only release one app that will be available in both free and
paid version, then I see no advantage. If you plan to release other
apps, you could achieve the same effect by adding to your test checks
on the package names as well as on the certificate. So I still see no
need for multiple certificates, which makes your own key management
more tricky.

mm
 But that's not really the question I want to make. I'll be releasing a free
 and paid versions of my app and I'm opting for the method where the paid
 app simply unlocks full functionality. I'll be using the process described
 in a thread around these groups. Where you check for the certificates of
 both packages and see if they match. If they do, then the user has unlocked
 the pro version.

 My question is about this specific situation. Is there maybe any reason I
 should use a unique certificate for these 2 apps? And if I release another
 free/paid pair in the same unlock model, I would use another certificate
 for those 2. I could then have another different certificate from the
 previous 2 for all other apps that do not use this unlock method or that
 are simply free.

 Is there any advantage in doing so? Or there is none and I should just use
 a single certificate for everything?

[android-developers] Re: Android SDK is the must buggy SDK in the entire mobile ecosystem.

2011-10-28 Thread Indicator Veritatis

They really do not like Windows at Google. I remember a news item
claiming that they were requiring all of their own developers to get
off of Windows and use either Ubuntu Linux or Apple OS X for
development.

Of course, they were supposed to continue to test for Windows
compatibility before release (and I am sure they do), but it is not
only at Google where they are best at testing and catching bugs in the
environment that they themselves use.

Strange though: I had no such problem when I upgraded my Win7 system's
Eclipse installation to use the latest Android SDK. But this is an
often overlooked factor in testing. Though it may be worse on Windows,
it is true on any platform: one user's installation will work just
fine, but another's will fail, even though both are the same OS and
very similar configuration. This is why test matrices have to be
carefully designed -- and tend to be large when they are.

As for 'alpha' level, yes, it is frustrating. But let's not forget: it
was Netscape that started the lamentable habit of putting alpha level
code out there and calling it 'beta'.

[android-developers] Re: What is the use of Handler object in the constructor of the ContentObserver class?

That is not the introductory article on the topic. You would have been
far better off saving taht deoc for reference and starting with
http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html,
which has long been the classic tutorial for covering database usage
and ContentProvider.

Now I admit, it isw confusing that there is no separate tutorial for
ContentProvider -- you are somehow supposed to magically glean that
Notepad is the tutorial/sample code to study. And there are multiple
version of Notepad in the sample code and tutorials, too. Really, a
nodding familiarity with all of them and a thorough familiarity with
one is the best preparation for understanding ContentProviders.

It is also helpful to remember a key phrase from
http://developer.android.com/guide/topics/providers/content-providers.html,
which you should also read before and after doing the Notepad
tutorial: Content providers store and retrieve data and make it
accessible to all applications.

That is the key difference between ContentProvider and any other way
of storing and retrieving data: it is accessible to all applications.
Now it also happens to be so that it is accessible by a UIR scheme,
but this, interesting and useful though it is, is secondary in
importance.

[android-developers] Re: What is the use of Handler object in the constructor of the ContentObserver class?

And now for a more direct answer to your immediate question: yes, you
are right. The Handler is for passing a message to the thread on which
it (the Handler) was created. But that is precisely what a
ContentProvider needs for receiving a message telling it that the
relevant database view has been updated.

That is what the verbage at the link you gave means, when it says,
This method [onChange] is called when a change occurs to the cursor
that is being observed.

Now just in case that was too brief and quick, let me connect all the
dots:

1) as you observed, the constructor ContentProvider(Handler) takes a
handler. The comment says, The handler to run onChange(boolean) on.
2) but this onChange is the one I mentioned above: ContentProvider has
to know which handler to use, so it takes that info in the constructor
argument
3) the mysterious 'cursor' is a database notion. It is roughly
analogous to the cursor on your computer screen, keeping track not of
LCD display but of the current read position in the database. So when
they say, cursor that is being observed, they are referring to
database changes.
4) Obviously if the ContentProvider is to work at all, it needs to
know about database changes, even if it is just just the current read
position (cursor) that has changed.

This will all seem SO much more clear when you see it in the Notepad
example code.

[android-developers] Re: HTC and LG haven't implemented Android in the right way

2011-09-27 Thread Indicator Veritatis

Now that I know what you are doing with the point attentuation, I see
that you are not using it for anti-aliasing, so that comment turned
out to lead to a dead end. As for why it is not supported, yes, it is
in the Open GL standard, but is it in ES? ES doesn't support
everything. And what do you get on those phones when you query
glGet(GL_POINT_SIZE_RANGE) and glGet(GL_POINT_SIZE_GRANULARITY) or
GL_SMOOTH_POINT_SIZE_RANGE and GL_SMOOTH_POINT_SIZE_GRANULARITY?

 Do you mean that I should make small rectangular polygons with
 transparent textures instead? I have tried that before on M3G and it
 didn't look as good as Point attenuation.

 Anti-Aliasing is a method of fooling the eye that a jagged edge is
 really smooth.Will that really be enough to get the same effect as
 Point attenuation? Could you please be more specific in which OpenGL
 technique I should use to make it work on HTC and LG?

 Isn't Point attenuation a part of the Android OpenGL standard?
 Shouldn't HTC and LG support it in that case?

  Short answer: no. Longer: why do you need point attenuation? There are
  other ways to do anti-aliasing, and some really cool graphics have
  been done for Android phones using that instead of point attenuation.

   I have found that everything implemented with Point attenuation will
   look like a blurry mess on devices from HTC and  LG. This happens on
   even the newest devices from HTC, like HTC Desire HD. Why is it like
   this? Haven't they implemented Android in the right way?

   Point attenuation works like it should on most Android devices, like
   those from Samsung. I have implemented Point attenuation according to
   the Android specification in two of my company's apps.I have worked
   with Point attenuation on Symbian and C++ before, so I am quite sure
   that I have implemented it the right way. It is about the same code
   implementation in all OpenGL.

   Shouldn't all new Android devices support Point attenuation? It works
   on IPhone, so I think Point attenuation should work on all new Android
   devices too.

[android-developers] Re: Image processing

You should start with the chapter on running Sobel Edge Detection on
Android using the NDK in Android in Action, 2nd or 3rd edition.

The 3rd edition is really written for Honeycomb, so you might want to
go ahead and buy the 2nd which is already available. Or go to the
website for the book and download the code, though it will be hard to
pick up much from it without the accompanying text.

For heavy duty image processing you are likely to want to use the NDK
rather than the SDK. Yet 'zxing' does surprisingly well without using
the NDK. That too is a good project for you to look at, since it uses
image processing for barcode decoding. The Java code is better
documented than many other open source projects.

 Give me some tutorial related to image processing using android. If
 you have created any apps using image processing in android please
 tell me about it.

 Thanks in advance.

[android-developers] Re: How to install APK programmatically without user prompt

What you need to do is pick your customers/clients more carefully. Any
client who asks you for such a feature either has completely failed to
understand the Android ecosystem or is up to no good. As already
explained, what you are asking for would break the security of
Android. This is NOT tolerable.

[android-developers] Re: How to install APK programmatically without user prompt

More importantly, sometimes these business people who come up with
special requirements in a business environment do not know what they
are talking about. What you are asking for, as Dianne explained, is
breaking the security model of Android. We will NOT help you do this.

 I honestly thing these are the most frustrating answers to get in a

 If you know the answer good, if you don't, please don't say that there
 is no good reason for doing this or that.

 We are not all trying to hack code behind our desks at home.
 Sometimes there are special requirements in a business environment
 that you have to implement and which people is not due and even
 allowed to tell you.

  Pratik,

  I think you should explain what you're trying to achieve with this and
  maybe someone can suggest an alternative.  There's no good reason why
  you should want to install an apk without user input as that would
  break security, so I think you just need an alternative approach here.

  Cheers,
  Oli

[android-developers] Re: How to do a Thread that only executes itself one time? (but continues alive)

Also, while you are on the topic of Threads and Loopers, 99% of the
time, if you think you need to create your own Looper instead of using
one created by the system, your design has a mistake in it. Handler,
HandlerThread and pre-existing Loopers should be enough. Even then
AsyncTask is often easier and better.

On Sep 26, 8:30 am, Kostya Vasilyev kmans...@gmail.com wrote:
 The exception is due to your thread not having a Looper, which a
 fundamental low-level mechanism used by Android to delivers events to an
 application. You can fix this, but

 You don't really need a thread for this - after you register a listener,
 the main thread will continue to run, receiving event callbacks as needed.

 If your app is having performance problems, take a look at what you do
 inside the listener callbacks and make it take less time.
