Hi,

I have an issue with photo taking in Android. The code below works for
all the phones I have, but when I am testing this with a Honeycomb
tablet (HTC Jetstream, in portrait mode), the picture will be taken in
landscape mode, then when it returns to the app, wipe out the view (as
if onCreate is being called again)!

How should I prevent this to happen? The code below is pretty standard
photo taking code. My guess is that the orientation changed is causing
the issue (even though the app is set to Portrait only). Thanks for
any help!

--
Taking photo:

  intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
  File file = new File(Environment.getExternalStorageDirectory(),
camera.jpg);
  intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
  startActivityForResult(intent, R.id.camera);

Set picture in view:

  if (result == Activity.RESULT_OK) {
File file = new File(Environment.getExternalStorageDirectory(),
camera.jpg);
view.setPicture(BitmapFactory.decodeFile(file.toString()));
file.delete();
  }
  else
Toast.makeText(this, R.string.error, Toast.LENGTH_SHORT).show();

[android-developers] Where does the picture saved to?

I am using this code to save the image:

--
String fileURL = Media.insertImage(getContentResolver(), bitmap,
KidsPaint, Picture);

if (fileURL != null) {
  Uri uri = Uri.parse(fileURL);
  sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
uri));
}
--

However, the result is pretty inconsistent. On my Nexus One - it goes
to the Gallery app, and on HTC Hero, it goes to the Gallery app but
does not show up until the device is rebooted. When I am testing on
HTC Jetstream Honeycomb tablet, it goes into the SD Card Camera folder
but does not show up at all in the Gallery app (and even reboot does
not help).

What have I done wrong and what's the best way to save a picture to
the Gallery app?

Thanks for advice!

Re: [android-developers] Calculate percentage of a video file

2011-11-24 Thread arun kumar

*Manually calculate the bitrate**
*The basic bitrate formula is

(*S*ize - (*A*udio x *L*ength )) / *L*ength = *V*ideo bitrate

L = Lenght of the whole movie in seconds
S = Size you like to use in KB (note 700 MB x 1024*°* = 716 800 KB)
A = Audio bitrate in KB/s (note 224 kbit/s = 224 / 8*°* = 28 KB/s)
V = Video bitrate in KB/s, to get kbit/s multiply with 8*°*.

*°8 bit = 1 byte.*
*°1024 = 1 kilo in the computer world.*

Example
90 minutes video, L = 90 x 60 = 5 400 seconds
700 MB CD but be sure that if fits use a bit lower like 695 MB, S = 695 x
1024 = 711 680 KB
Audio bitrate, A = 224 kbit/s / 8 = 28 KB/s

(711 680 - (5400 x 28) ) / 5400 = 104 KB/s x 8*°* = 830 kbit/s.

Dear Karthik,

I would like to recommend you to use the following code snippet in your 
activity.


@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {

super.onKeyDown(keyCode, event);

if (keyCode == KeyEvent.KEYCODE_BACK  
event.getRepeatCount() = 0) {

*   //it is for long press *
return false;
}
if (keyCode == KeyEvent.KEYCODE_BACK  event.getRepeatCount() 
== 0) {


*   //It is for one time press*

return true;
}

return super.onKeyDown(keyCode, event);
}


Regards
Prashant Lal

 - then user click each link will load new url in same WebView;
 - user click back to Main page;

 the problem is when user back to Main page, user cannot see any

 I tried my page on IE and FF, both works fine, but had problem on

 My sample code as below:

 // set settings for webview

         webSettings.setBuiltInZoomControls(true);
         webSettings.setJavaScriptEnabled(true);
         webSettings.setUseWideViewPort(true);

Re: [android-developers] Re: Calculate percentage of a video file

OK

Then now i am doing

video.pause();
   int current=video.getDuration();
int total= video.getCurrentPosition();
int per = (current*100)/total;


This is right way for calculate percentage of video?


because when it's reach near 90% then i want to fire a action on the
basis of figured value.

[android-developers] Re: Where does the picture saved to?

I saw a solution here (http://www.rical.net/blog/
article-1318132709.html), not sure whether this is true as I didn't
see this explanation elsewhere. What it means is that
Media.insertImage() returns the Uri will be in content:// format,
but ACTION_MEDIA_SCANNER_SCAN_FILE intent required format in
file://. This explains why scan files/refresh does NOT work!

Here's the code below, what do you all think?
--
Uri uri = Uri.parse(szUrl);
String[] proj = { MediaStore.Images.Media.DATA };
Cursor actualimagecursor = managedQuery(uri,proj,null,null,null);
int actual_image_column_index =
actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
actualimagecursor.moveToFirst();
String img_path =
actualimagecursor.getString(actual_image_column_index);
uri = Uri.parse(file:// + img_path);

// Send intent
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri));

 You could come up with a business model that does not depend upon
 defeating pirates.

It was never my intention to come up with a business model that tries to 
defeat pirates. That's something I'm not worried about, I didn't even 
mentioned piracy in any of my posts. That's really not the issue. I'm just 
trying to understand how secure is SharedPreferences and what alternatives 
are there, that's all.

Re: [android-developers] Re: How secure are SharedPreferences on rooted devices?



 Thanks. This is very basic, so if you decide to use it, you may want to
 improve/tweak it. At least you need to decide how you manage coupons:
  by device (how do you identify devices?), user (google account, email), 
 etc.

I haven't yet installed anything of that but one way would be to have a 
notes field for each coupon you create and then you identify each coupon 
the way you want it. By device, by user, whatever... Or you can just do 
that on a separate document and keep a list of coupon codes and to which 
user/device it corresponds to...

But I liked your other idea , I'll investigate that one...

[android-developers] Re: Where does the picture saved to?

I replaced the ACTION_MEDIA_SCANNER_SCAN_FILE intent by
ACTION_MEDIA_SCANNER_SCAN_FILE intent for saving, and it works for HTC
Hero issue! Now Gallery will be refreshed when we save the file.

sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
Uri.parse(file:// + Environment.getExternalStorageDirectory(;

//  sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
uri));

It still does not work for HTC Jetstream (the pictures do not show up
in Gallery). I am not too sure whether it is a good solution though.

Do you allow 1 person to use it on 3 different devices? What happens
if I reset my phone, can I re-use your coupon (same user, same device,

[android-developers] Someone has the Galaxy Nexus? :)

2011-11-24 Thread YuviDroid

Hey everyone,

while I'm waiting for the Galaxy Nexus to be available here in Switzerland
I was wondering if somebody who already has it he's willing to quickly test
my app to see how it works there?
(especially with respect to the high screen resolution screen and the
'menu' key not being present). Btw is the Galaxy Nexus a hdpi or xhdpi
device?

I already tested on the emulator (well...kind of...) and on my Nexus S with
ICS 4.0.1...but I'm really curious to test it on the real thing :)


Thanks,
Yuvi

[android-developers] C/C++ struct in android

2011-11-24 Thread Aitor Mendaza Ormaza

Hi to everyone:
I want to make something similar to a struct in C/C++, to represent a
collection of structured data.

I first though of making objects with properties, but this might be a
little inefficient (creating objects just to store data).
Is there a more efficient way to do this in android? Something like structs
:)

Thanks in advance!!!

 So unless you can live with the significantly smaller screen-real-
 estate that the Action Bar will leave you with, the only solution
 seems to be to leave the target-SDK setting at 9, as to ensure Android
 will always display a menu key on the screen.

Or, don't run ads

Or, put the ad in the action bar, if they have an ad size that fits

Or, switch to a different ad style (e.g., interstitials) that does not
take up continuous screen space

Or, skip the action bar and don't use menus, putting whatever had been
in your menu in the UI proper, as many games do

Or, skip the action bar simply plop your own PopupMenu in the
upper-right corner of your UI triggered by an ImageButton using the
same icon as the action bar itself uses for the overflow menu

There are probably other solutions as well, but these should get you started.

I jut wanted to know if there was a way around of using class only for

Re: [android-developers] screenshot in android

2011-11-24 Thread Mukesh Srivastav

Let me give u an Example:

Let's say you have a layout and it has a parent layout could be
(Relative,Absoulte or LinerLayout). Take the id out of it. Below are the
steps to do this.

Step 1: Declare a Variable

View screen;

Step 2: in public void onCreate(Bundle savedInstanceState)  Method

   screen = (View) findViewById(R.id.captureimagelayout);  // Change your
Layout id here.

Step 3:   in the Button onclick Listener do this.

screen.setDrawingCacheEnabled(true);
Bitmap imgToSave = screen.getDrawingCache();


Step 4: in the Step 3# you have the Bitmap object,  use File:\\ operations
 to save the bitmap.  you are done.
As simple as that.

Re: [android-developers] screenshot in android

on a rooted phone you can dump the contents of the framebuffer into a 
bitmap and then convert either of the frames (the buffer has two) into 
whatever image format you want. something like cat /dev/graphics/fb0  
grab.raw

Re: [android-developers] Re: How secure are SharedPreferences on rooted devices?

exactly. Rather than thinking about the technicalities first, approach the 
issue from the other side. What is your user population like? Average users 
that never change phones? Geeks that flash a new ROM every week? Silent 
majority versus vocal few trolls? Once you have decided how you want to 
serve your customers you can then design your verification process.

http://developer.android.com/guide/practices/design/performance.html

Object creation is never free. A generational GC with per-thread
allocation pools for temporary objects can make allocation cheaper, but
allocating memory is always more expensive than not allocating memory.

If you allocate objects in a user interface loop, you will force a periodic
garbage collection, creating little hiccups in the user experience. The
concurrent collector introduced in Gingerbread helps, but unnecessary work
should always be avoided.


For what is worth, I don't choose not to believe Mr. Bloch, I was just
wondering if in Android were better choices for classes as structs, as I
know my knowledge of both Java and Android is limited. That's the reason I
asked here after searching the web with no results (again, maybe my results
weren't good enough to get the answers I was looking for).

Thanks, though, for the link, as it seems interesting.

 A plugin is packaged like a standard apk and can be installed either via the

 I am not 100% sure how it should work, but my expectation is that when

 In the Android web browser settings is an option to enable/disable

Android doesn't add anything to the Java programming language. It adds
(and removes) from a standard Java class library, but the language is
the same. Hence, Android did not introduce any new language concepts
like a struct. The objective here is maximum compatibility with Java
5/6 code.

Advice for ordinary Java is *generally* a good starting point for
Android -- the places where Android will differ is not in language
features but in VM implementation (e.g., garbage collection). The
biggest exception to this rule will be anything written about Java 7,
as Android does not officially support it, and so you may encounter
problems with new Java 7 language features.

It's your app, so you should know best... But,

If you are worried about shared preferences being insecure, you should
probably be worried about one of those persons posting his coupon to a
forum, etc. If you allow coupon sharing, everyone would be able to get
the full version using that coupon. If you think the risk is small enough,
it's OK to ignore this, but you should at least consider the possibility.
It's a lot easier than rooting your phone and changing preferences
manually.

[android-developers] Persistence of complex Java objects (SQLite, Serialization, JSON) and client-server app architecture

2011-11-24 Thread Christine Daunique

I'm working on an Android application which is fetching data from
internet among other things. Actually, the project was started by
someone else which is not here anymore, and now that I have to turn it
into a light client application and implement the server side (in
Java), I'm wondering what would be the best tools/patterns to use to
fit my needs.

Let's say I have to deal with several models (class representing a
category) of objects which all inherits from one class : they have
common attributes (such as name, attache thumbnail...) but specific
properties too. Because of this,you can understand that I can't afford
to manage one specific table to map each single class.

However, I still want to be able to cache my objects somewhere in the
Android device to populate the views of the application when working
in offline mode.

Currently, the solution used by the previous developer was to store
data directly into a TEXT field in the SQLIite database, as serialized
objets. This should be ok on the server side but I've read that the
usual Java serializaton was very slow on the Android platform,
although it is not really noticeable now because I work with around
~50 objects, I was looking for more performant alternatives for the
future.

I've came across the JSON solution which can easily handle complex
structures and Jackson library seems very interesting with its
simplified data binding to POJO objects and its well-known
performance. But then, how should I store my Json objects ? Is it
possible to keep a json string in a TEXT field of a SQlite table ? Or
should I rather store them as .json file for each object ? Which one
is the more efficient to retrieve later lot of data?

Plus, I was thinking that JSON would be a very good exchange format
between the Android client application and my server whould is in
charge of processing the information from internet third-parties apis
and exposing this data with webservices.
Is using the usual Apache HTTPClient enough on Android to communicate
with the server?

For those who successfully developped client-server application (which
seems very common to me) is this a good approach for Android ? It
seems to me that with mobile platforms, you can't really use the
approach that you've learned for more classic J2EE app and such... Any
advice would be greatly appreciated because I'm a student and Android
beginner who really want to improve her mobile development skills !

Thanks :)

  How is the situation with the Android browser plug-ins?

  - Can we develop the browser plug-in?
  - Are there any limitations of what the plug-in can do?
  - Can it be developed in C or Java only?

  I swa here (https://www.codeaurora.org/git/projects/qrd-gb-dsds-7225/
  repository/revisions/cc99b832a941dc8cbb86f1607d04eb87935ddbfd/entry/
  android/development/samples/BrowserPlugin/README):

  plugin is intended to give plugin developers a point of reference to
  see how an android browser plugin is created and how to use the available 
  APIs.
  A plugin is packaged like a standard apk and can be installed either via 
  the
  market or adb.

  But I did not found anything on the official developer.android.com
  pages as well as any plug-ins and on Android Market...

  I am not 100% sure how it should work, but my expectation is that when
  browser loads an
  HTML page that contains the new MIME Type in Object tag, then
  Android brower should
  and create instance of associated my browser plug-in.

  In the Android web browser settings is an option to enable/disable
  plug-ins...

[android-developers] Re: How secure are SharedPreferences on rooted devices?

2011-11-24 Thread Kevin TeslaCoil Software

I'm just
trying to understand how secure is SharedPreferences and what alternatives
are there, that's all.

On a rooted device SharedPreferences absolutely can be tampered with.
Same with any on-device storage. However this doesn't mean you can't
use them.

1) Obfuscation. This is how Google recommends handling LVL data in
shared prefs. This is not secure as someone could reverse engineer the
obfuscator, but it makes it a pain in the ass and generally not worth
it (easier to crack the APK itself). Check out the
PreferenceObfuscator used for LVL:
http://code.google.com/p/marketlicensing/source/browse/library/src/com/android/vending/licensing/PreferenceObfuscator.java
. It gives you stuff like this: string name=5h99XZgr
+0i5N2SN0lEDu592x14RTrTj6/VOCCnxGokeazVz9bfLW793kkXg01kaBsJa1//
string
You can seed the obfuscator with a device id of some kind to prevent
users from just copying shared prefs from one device to another.

2) Server signed data. When you authenticate your coupon, instead of
saving a true or false, save a string from your server that is
cryptographically signed. At the launch of the app you can verify this
signature even without internet access. Again this is similar to the
LVL approach. It might be too much work as crypto is very confusing.

---

Along the lines of what others are saying, don't invest too much in
anti-piracy stuff. Release and see what happens, if no one cracks it
then don't waste any more time. If it's cracked, look at how they did
it and block it in the next update. Keep adding features in updates
will keep current and future legit users happy, and have the pirates
always playing catch up to the latest version until they get sick of
it and just buy it.

The method will not return true until the view has been attached to a

 Again, you need to get your units straight


That chore list isn't getting any shorter!

One knows the length of the video file up front, be it in seconds or KB or 
whatever unit,  The only tricky thing is to determine what fraction of that 
size/length has been consumed at a particular point in playback.

The technique depends in part on how precise you need to be.  If you're 
just showing a progress bar, or calculating to, say, the nearest 5%, you 
can probably get away with ignoring the wobble factors like CRC, perhaps 
with a correction applied every 100 MB or so to reduce cumulative error. 
 If you need ppm resolution your calculations will need to be more precise.

You can measure time or you can measure stream size.  If you know the 
number of seconds of the entire video, and you have the current tickmark 
from the video, then Bob's your uncle.  You can skip all that fooferol of 
bytes/second, yada yada, and just use the timestamp-to-duration ratio.  If 
you cannot get at that data, you can use the system clock to approximate, 
but you'd have to factor out any pauses, fast-forward or whatnot.

I'd venture that dealing with rewind, pause and fast-forward will cause you 
more trouble than the raw calculation of ratio completed.  It all hinges on 
determination of your current position in the video.

Re: [android-developers] C/C++ struct in android

A  struct would /be/ an object, thus its overhead would be the same as for 
a class, because in Java, a class *is* a struct, or to put it another way, 
there is no such thing as a struct, and if there were, it would be an 
object.  How do you think you can create an object for free by calling it a 
struct?

As for trying to optimize object creation and GC, what makes you think that 
poses a problem for you?  Where is your evidence - your profiles, timing 
measurements and description of the loads and other conditions under which 
you tested them?

And if you have such masurements, which I sincerely doubt, how would using 
a struct have any remote possibility of improving on that?

Don't waste your time looking for solutions to non-existent problems.

 Upon first exposure to the Java programming language, some C

 structs under some circumstances, but this is not the case. Degenerate
 classes consisting solely of data fields are nearly equivalent to C
 structs in every respect.

 If you choose not to believe Mr. Bloch, that is your decision.


 http://developer.android.com/guide/practices/design/performance.html

 Object creation is never free. A generational GC with per-thread 
 allocation pools for temporary objects can make allocation cheaper, but 
 allocating memory is always more expensive than not allocating memory.

 If you allocate objects in a user interface loop, you will force a 
 periodic garbage collection, creating little hiccups in the user 
 experience. The concurrent collector introduced in Gingerbread helps, but 
 unnecessary work should always be avoided.


 For what is worth, I don't choose not to believe Mr. Bloch, I was just 
 wondering if in Android were better choices for classes as structs, as I 
 know my knowledge of both Java and Android is limited. That's the reason I 
 asked here after searching the web with no results (again, maybe my results 
 weren't good enough to get the answers I was looking for).

 Thanks, though, for the link, as it seems interesting.

Re: [android-developers] screenshot in android

As stated by another poster, this technique will not give you a _screen_ 
shot but a image of GUI elements within the activity.  They are not quite 
the same.  Also, some techniques for grabbing frame-buffer data can 
retrieve partially-drawn frames.

The only way I've found to reliably obtain a full-screen shot is via the 
DDMS library or equivalent (monkeyrunner,ChimpChat).

 If you are worried about shared preferences being insecure, you should
 probably be worried about one of those persons posting his coupon to a
 forum, etc. If you allow coupon sharing, everyone would be able to get
 the full version using that coupon. If you think the risk is small enough,
 it's OK to ignore this, but you should at least consider the possibility.
 It's a lot easier than rooting your phone and changing preferences
 manually.


That's why, and for other reasons of course, the cupon system I linked 
above allows you to disable a coupon. If someone does something like that, 
they simply broke my trust and I shall invalidate their coupon. Than, no 
one else can use the app with that coupon. Of course I'll need to wait for 
them to pen my app while connected to the Internet so I can invalidate the 
coupon (cause like I said, I don't want to force an Internet connection to 
run my app every time).

What you /should/ do is make sure that references point to something other

 what you are looking for is a result of many design types telling
 people that code handles nulls

 it doesn't = you have to go look for it and find it

Maybe if there were some punctuation, capital letters, and complete 
sentences in there I could understand what this guys is suggesting.

when you do, fix it some way.


I agree with this advice, which boils down to the oh-so-insightful 
suggestion that analyze the problem, determine a solution!  That's good 
advice, and I'm sure you'll find it exceedingly helpful.

Not.

NullPointerExceptions, like other RuntimeExceptions, are a result of 
programmer error, in this case yours.  It means that you have a pointer 
still pointing to 'null', but you tried to use it as if it pointed to 
something not 'null'.  You have to assign your pointers to something not 
'null', and you have to check your pointers before dereferencing them to 
make sure they aren't 'null'.

As stated upthread, the stack trace (plus my hint) will tell you which 
pointer was pointing to 'null' when you tried to dereference it.

If what you want is to be able to give out free copies to some users,
implement another unlocker, that is similar to the paid premium unlocker
you're planning for Market, but is free.

Encrypting preference data has nothing to do with LVL per se, and does not
require that the app is paid or free.

Whatever encryption / obfuscation you choose to go with, make sure to throw
in some device-specific bits, so your data file with the activation state
won't work if copied to another device.

1) Obfuscation. This is how Google recommends handling LVL data in

it (easier to crack the APK itself). Check out the

On Sunday, November 20, 2011 7:45:01 AM UTC-8, MosToneDef wrote:

 Dear Google;


This isn't Google, this is the Android Developers discussion group.
 

 I've been a Chrome user since its release. I've visited your app
 store  many times. I  recently received my Android phone and have been
 perusing your Android Market.

 I've noticed one very disturbing theme in both the Chrome Store 
 Android Market: The use of the word Addictive.


Really?
 

 I don't have to go into issues of how bad this word is and how it's
 tagged into so many game descriptions.


You didn't have to post this drivel, either, but you did.

The word isn't bad.  Fuck is a bad word, addictive isn't.

You are wrong.
 

 Another argument that works too is: How does a game developer decide


There should be a comma before and after the word, too.
 

 their game is good enough to become addictive? Utilizing this word/
 term/phrase/social label as a sales gimmick, is gratuitous at best.


How does any marketeer decide what adjectives to apply to the product or 
service they market?

Maybe you should Google for that information.


 I would like Google to ask themselves these questions:


 1. Do we want to be recognized  as a corporation that intentionally
 produces content that we hope users will become addicted too?


We?  Are you part of Google?
 

 2. What kind of consumer are we trying to attract with the term
 addictive?


I think that's obvious - a game-playing consumer who wants to be fully 
engaged with the game.

Duh.
 


 3. Why is the developer of this app resorting to the word addictive
 and why doesn't the developer resort to other responsible language to
 sell their product?


Begging the question of what constitutes responsible language.  Your 
whole fetish with the word addictive looks like irresponsible behavior to 
me, personally.

I think you're addicted to political correctness.
 


 4. What responsible language can the developer use instead of the term
 'addictive?


First, define responsible language and why anyone should endorse your 
idiolectic use of the term.

Calling your idea responsible and everyone else's irresponsible is 
fallacious - you have provided no reasoning to induce anyone to accept how 
you've framed the discussion.  You just resort to rhetoric and baloney, 
devoid of logic or evidence or other merit.
 


 5. When has the word addictive ever been a good word?


Since its inception.
 

 6. How is using the term addictive acceptable, but people who are
 labeled addicts, pariahs?

Different meanings in different contexts, Your arguments hold less water 
than a sieve. 
 

 7. Do we need to rely on the word addictive as an ongoing selling
 point?


We don't, but others are certainly free to.
 


 8. Should Google have content that people simply want to use out of
 need, not to fulfill an addiction?

Need?  No one needs a smartphone, much less the games on one.  The 
neuro-liniguistic programming evident in your phrasing inidcates that you 
have addiction issues, referring to luxuries as a need and being all 
obsessed over the word addiction in only one of its many meanings and 
connotations.


 9. Does Google want to rely on the term addictive as a statement of
 quality and playability?


Does Google do that in the first place?  You have not provided any evidence 
that Google does this.
 


 10. What is the difference between wanting to play a game  needing to
 play a game?


You're the one who talks about need.  I suggest you answer that question. 
 It's irrelevant to the marketing tactics to which you refer in any case.


 11. Is Google willing to accept that, when an addictive state of mind
 is realized, ALL choice is removed from our consumer?


Facts not in evidence, thesis is bullshit anyway.
 


 12. Are individuals who are performing any act out of obsession or
 compulsion, having and enjoyable experience?

What individuals are those, and how does that have any relevance whatsoever 
to the marketing technique in question, that of using an innocuous word  in 
one of its innocuous meanings?

13. Is our product something we want our customers to get better from?

Our?  Who is us in this context?  Google?  You aren't complaining about 
Google's products.  To what group or organization do you belong that is the 
antecedent for our?

I ask that Google make some changes. I also ask anyone reading this to


To what?  What independent developers do?  How should Google decide to 
dictate free-speech limitations to people that don't work for it?
 

 abstain from purchasing or interacting with any application that
 contains the base word addict and all it's forms.


The word is its, not it's.
 


 Finally, a simple word search in the Android market proves my point.
 You get multiple hits in games. And you get even more multiple hits in
 self help appsnow that's strange. It's like a candy company
 selling insulin.

No, it isn't.  Your thesis is crap from the ground up.

This might or might not have any effect on performance, much less a 
noticeable one.

The OP has shared no evidence that they have a performance problem, related 
to GC or otherwise.

There is no evidence that your approach would help, because changing the 
lifetime of objects influences GC in sometimes unexpected ways.  Even if 
the array approach did shave of a few milliseconds here or there, the added 
complexity of manually taking over memory management could create slowdowns 
and likely would create errors, and the effect on overall application 
performance would still be negligible.

If the OP is really concerned about performance, and willing to behave like 
an intelligent person, he can *measure* the app's performance under 
realistic conditions, *profile* it and determine where the inefficient 
spots are *before* and *instead of* engaging cargo-cult superstitions about 
what will help.

If you double the speed of something that only took 0.01% of overall 
execution time, but you have tripled the maintenance costs for the whole 
app and added new bugs that require new fixes, how is that a win?

 This might or might not have any effect on performance, much less a
 noticeable one.
 The OP has shared no evidence that they have a performance problem, related
 to GC or otherwise.
 There is no evidence that your approach would help, because changing the
 lifetime of objects influences GC in sometimes unexpected ways.  Even if the
 array approach did shave of a few milliseconds here or there, the added
 complexity of manually taking over memory management could create slowdowns
 and likely would create errors, and the effect on overall application
 performance would still be negligible.
 If the OP is really concerned about performance, and willing to behave like
 an intelligent person, he can *measure* the app's performance under
 realistic conditions, *profile* it and determine where the inefficient spots
 are *before* and *instead of* engaging cargo-cult superstitions about what
 will help.
 If you double the speed of something that only took 0.01% of overall
 execution time, but you have tripled the maintenance costs for the whole app
 and added new bugs that require new fixes, how is that a win?

But the whole point is moot:  the vm optimizes things beyond what you
would think.  If you want to know the optimizations that the vm makes,
you can read about it, and unless you do investigate it there's not
point in worrying about it.

(For example, the vm cuts out functions with no effects, think Object
constructor, does jit compilation, etc...)

So until you investigate the details, or have profiled and found a
problem, there's not really any point in worrying about it.

[android-developers] Re: Lists with white background and black color

There's an error in the build.xml file at

project name=ListViewDemo default=help

default target help does not exist in this project

How do I correct this?

 Throwing android:theme=@android:style/Theme.Light on the activity
 in this project works just fine:

 https://github.com/commonsguy/cw-android/tree/master/Selection/List

 Download that project, add in the theme, and run it. If it works, then
 the problem is something with your project. If it does not work, then
 the problem is something with your device or emulator.

Re: [android-developers] Re: Lists with white background and black color

Run

android update project -p .

from the project directory. I haven't updated the repo for that
project since the new build tools, sorry.

It updated the local.properties and proguard.cfg files but the
error in build.xml still persist.
