[android-developers] Android Studio Support for AspectJ Programming

[Hari V]

As per the features provided by IntelliJ , AspectJ is only supported in 
Ultimate Edition 
https://www.jetbrains.com/idea/features/editions_comparison_matrix.html

Does Android Studio Support AspectJ? 

I tried the following

   -  Compiling *.aj files directly 
   - Using plugin which have (*.aj file and corresponding *.java classes ) 
   with Android Project to use with Android Studio.

If these dependencies had got configured correctly, I was supposed to get 
log's in Logcat generated by AspectJ . But could not get the logs.


Where as the same is still working with Eclipse environment !  The issue 
has been described in StackOverflowLink 



Any help is highly appreciated.

[android-developers] Determine Application State (Foreground/Background) when onNewIntent() is called due to URL scheme

[Piyush Hari]

onNewIntent() of MainActivity with launchMode 'singleTop' is called when 
application is invoked using its registered URL scheme. 

The order of call is :

onPause (app is entering in background)
onNewIntent (open url intent passed)
onResume (app is in foreground)

In onNewIntent(), how can one determine if application was running in 
foreground when the open url intent arrived ?

If I decide to track the state using a flag inForeground that is 
initialized to false and set to false in onPause and true in 
onResume, applicationState will always be background (inForeground will be 
false in onPause).

[android-developers] Proxy streaming in Stagefright does not work on some devices

[Hari KJ]

Hi All,

I'm working on a mp3 streaming app and have used the NPR's StreamProxy
class. For some devices which have sdk 8 (like EVO on Sprint) the
native mediaplayer streaming of mp3 sounds really really bad. The same
code works perfectly fine on HTC Incredible and all samsung devices.
Evo seems to have some problem when using the native mediaplayer to
directly stream the mp3 audio.

When I tried to force proxy the stagefright player on my device (HTC
Incredible) works perfectly fine but the EVO bails out. I have also
overridden the http headers and appended /r /n to the header values,
as I had read in some of the other blogs.

What should I do to overcome this and force a proxy? Or how do I fix
the bad mediaplayer playback in devices like EVO?

Any help would be greatly appreciated.

-Hari

[android-developers] Re: How to reverse camera view?

[Hari Edo]

I'm not sure what the value of such a preview
would be-- I thought you wanted it mirror-flipped,
but you're swapping left and right halves of the image.

You may want to read through this thread.  The
challenge is to keep your processing code lean and
efficient enough, since a phone is not going to have
a lot of CPU cycles to devote to real-time video
manipulation.

[android-developers] Re: How can we get the mobile position (e.g. by gps) all the time?

[Hari Edo]

Theoretically, a perfect accelerometer would give you your relative
velocity
change, and if you knew the initial velocity, you could get your
relative
position change.

In practice, you don't have a perfect accelerometer-- they have sample
rate limits that are pretty coarse for kinetic analysis, and it's easy
to
exceed the force limits giving you garbage data samples.  MEMS are
amazing
things, and oh so inexpensive, but they're not magic.

On Apr 27, 7:20 am, lbendlin l...@bendlin.us wrote:
 TreKing, this just gave me an idea. How about a hybrid between GPS and
 accelerometer?  Keep the GPS listener running until there was no position
 update for, let's say, 20 periods. Then disable the GPS listener and enable
 the accelerometer listener. Once movement is observed, restart the GPS
 listener.

 Now of course the big question is how the power consumption compares between
 the two...

[android-developers] Re: HttpURLConnection responsecode 414-url too long issue

[Hari Edo]

As another poster was hinting, this is a job for HTTP POST, not
HTTP GET.

GET puts all arguments into the URL.  POST puts a short URL, and
then adds all of the arguments to the hidden handshaking
conversation that follows the network connection.  The good news
is that many CGI programs don't even notice that you've made the
request in a different way.  The program just gets its arguments
and is happy.  The bad news is that this is not guaranteed.

(A side benefit of POST is that all of these ugly or semi-
private facts don't show up in the URL.)

If you can't accept HTTP POST arguments this way for some
reason but you can modify the CGI script (recipeBatch in your
example), then you may get a little farther by compacting the
arguments a bit.  You have a couple hundred copies of the
characters 'ids='.  Make it one argument with + separators,
and split it on the CGI side.  That gives you a little bit
of room, but it's not unlimited by URL length like POST is.

I am hoping that those 7-digit numbers are not phone numbers.
I'd hate to think I was helpful AT ALL to someone building
an annoying telemarketing system.

 Why would you need Honeycomb source?


I think the issue is not need vs want.  Yet.  It's doing the right
thing.  If a network router uses some open-licensed code, but doesn't
provide the sources, they are rightly brought to task for it through
a legal challenge.

If Motorola has shipped stock Honeycomb 3.0 (per words from Google
reps here), then Motorola's users should have access to the software
on
the device.  While you can quibble about distinctions between Apache
vs GPL, and deltas from version 2.3 to version 3.0, the point is the
same:  users can't call it OPEN unless the users can have the CODE.
For Google to call it OPEN when users do not in fact have the CODE is
disingenuous at best, and becomes more nefarious over time.

Google's really good at hoovering in all kinds of data and coming up
with some sort of corporate strategy from it.  Google has not shown
the same level of ability at communicating in the other direction.
If we developers are going to be Google's partner in making Android
a success, then Google needs to communicate with us.  That goes for
Android Market, Android Platform, and all other areas upon which we
mutually depend.

[android-developers] Re: Chinese soft keyboard and unknown character set

[Hari Edo]

The characters are made to be the same width as all other
Chinese characters, so that text will align as expected.

Even if I knew NOTHING about Unicode, or UTF-8 encoding,
I might decide to type all of the digits on the Chinese
soft keyboard, then cut and paste them into my Java code,
making a nice little filter with similar logic:

 if (ch == '１') ch = '1';
 if (ch == '２') ch = '2';

And so on.  If I looked at the integer values of each
character, I might notice that they're all in the same
order, so I could do something more sophisticated for
all conversions in one statement, like:

   ch = (char) ( (int)ch + (int)'1' - (int)'１' )

Some things require problem-specific code.  I would
suggest reading up on Unicode, and browsing the
UTF-8 or Unicode code tables to learn a bit more.

Were you hoping for a magic DWIM API that just
would Do What I Mean for any and all situations?

Eclipse will put a little arrow in the left margin if you

On the first loop, take the value and smear its bits
once rightward:

  x was:10010111
  x  1:   01001011
  x | x  1:   11010001

On the second loop, you could smear the bits once
rightward again (doing i++ in the for loop), but that
would be a waste of time since there can be no more
single 1 bits.  All the runs of 1 bits are now fatter.
So on the second loop, smear the bits TWICE rightward,
by doing (i = 1) in the for loop instead.

  x was:11010001
  x  2:   00110100
  x | x  2:   1101

On the third loop, smear the bits FOUR rightward,
since any 1 bit is now fatter.

  x was:1101
  x  4:   
  x | x  4:   

We're done in this example, but the loop here
also tries to smear by 8 and smear by 16.

We then add 1, to roll over to the next power of
two.

  x was:
  next power:   0001

However, because you don't want to have the
nextHighestPowerOfTwo(2048) to return 4096,
the function starts with x-1 instead of x.

[android-developers] Re: On Click method not working for buttons gotten by inflating the layout!

[Hari Edo]

You're inflating a whole layout, then attaching a listener to it,
then throwing the whole layout away.  There's nothing here showing
that the layout you've inflated is actually shown or attached to
the current activity.  If it's not on the screen, it's not going
to react to clicks.

Normally, you call your activity's .setContentView() with an ID
of a layout (R.layout.level), and that does the inflating and
more importantly, the continual display of said layout.  You
can then use .findViewById() to grab various buttons or other
view types in that layout.

setContentView(R.layout.level);
Button updateLevel = findViewById(R.id.updateLevel);

If you are inflating portions of a whole activity's layouts,
then be sure to add those inflated views to the activity's
existing containers (layouts).  For example,

setContentView(R.layout.whatever);
ViewGroup group = (ViewGroup)findViewById(R.id.levelgroup);
View level = getLayoutInflater()
.inflate(R.layout.level, levelgroup, false);
levelgroup.addView(level);
Button updateLevel = levelgroup.findViewById(R.id.updateLevel);

 All my other On Click methods work except the ones the I have to

 Here are how I define my On Click listeners for the problem buttons:

 Button updateLevel =
 (Button)getLayoutInflater().inflate(R.layout.level,
 null).findViewById(R.id.updateLevel);

         updateLevel.setOnClickListener(new View.OnClickListener() {

                 });

    Button goBackMainMenu = (Button)
 getLayoutInflater().inflate(R.layout.play,
 null).findViewById(R.id.tomenu);
         goBackMainMenu.setOnClickListener(new View.OnClickListener() {

                         @Override
                         public void onClick(View v) {
                                 toMenuOnClick(v);

                         }
                 });

 Here are my onClick actions:

 protected void toMenuOnClick(View v) {
                 setContentView(R.layout.main);

         }

         protected void setLevelOnClick(View v) {

                 setContentView(R.layout.main);

         }

I've used katakana and hiragana extensively in textviews, no problem.
This is a pretty suspicious error report-- is it JUST that string?
Is it only when the textview is in a listview?  What's the full stack

if you change the text on an on text changed listener, etc.?

Threading only helps separate the computation from the visuals,

The most common filtering done, from Wiimotes to Google Star Map,
is kalman filtering.  It can take a bit of time and effort to

[android-developers] Re: database and maps

[Piyush Hari]

Putting latitudes and longitudes is one way. Putting just the address
and geocoding it before displaying on map is another. The caveat with
the latter approach is that geocoding everytime you retrieve data is
costly. Since latitudes/longitudes associated with addresses do not
change, it is best to store lat/lng in dB after geocoding the address
at the time of inserting the entry in db.

The Android SDK setup for Eclipse does integrate with the ProGuard

honest people will be happy to pay for.  You'll never achieve 100%

[android-developers] Re: how to change behavior of default application in android

[Hari Edo]

I think you're confused about how Android picks apps (activities)
to handle various commands (intents) that the user invokes.

Roughly:

  * the phone radio kit receives a call
  * Android asks, hey, which app is able to answer calls?
+ If one app says it can, that app is assumed the default.
+ If more than one app says it can, and one has been marked
  as the default, that app is used.
+ If more than one app says it can, and no default is marked,
  the user is shown a list of choices.
+ The user can make a choice and use it this time.
+ The user can make a choice and mark it as default for
  future situations as well.
  * Android uses the chosen app to display a receive call UI.

This scenario is not just for receiving calls.  It also works
for responding to the Home button, and many many many other
situations in the Android system.

You don't get hooks or callbacks for when applications finish--
even the app itself may not be notified that it's being killed.

You cannot disable this search for intent handlers mechanism.
It is at the core of what makes Android... Android.

[android-developers] Re: SIGSEGV on free()

[Hari Edo]

This has nothing to do with Android, per se.


Calling free(x) when x is NULL is not harmful.
Calling free(x) when x came from malloc() is not harmful.
Calling free(x) twice with the same value of x will surely SIGSEGV.
Calling free(x) with a bad value will likely SIGSEGV.

Note case 3:  if you call free(x), follow it immediately with x=NULL,
and you will probably not crash anymore.  Matching your malloc()/
free()
calls carefully and logically tends to fix such problems.

If that's all that you changed, and it fixed the

Touch devices have different semantics.  They simulate the
onmousedown/onmouseup events for backward compatibility, but
you really can't assume they will work the same way.

For example, how would you scroll a webview if it replied to the
initiation of every touch instantly?  The touch, stroke, lift
has come to be known as a scrolling gesture, and the web page
should not receive any onmousedown/onmouseup events.  If you
touch and lift without stroking, only then can the system know
you're not trying to scroll, and it offers the onmousedown/
onmouseup events at that time.

However, the one big rule about toasts:  no touch, click or typing

[android-developers] Re: Help Getting the Context

[Hari Edo]

One alternative is to look for, or create, a public singleton.
A public singleton is a class that (1) ever only has one instance,
and (2) that instance can be located from anywhere by means of a
static method.

One candidate for singleton status is Application -- it is a Context,
and you expect there'll only be one of them.  In your extension of
Application, have the constructor save 'this' to a static field, and
have a public static method to get the saved reference.  Voi la, you
can now get a useful Context from anywhere.  Most apps don't use an
Application extension, but you can use this pattern on pretty much
any class.

 If I had a context I would call

 How do I obtain a context in this situation?

 I would prefer not passing in the context to the class constructor.  Am

Yes, indeed.  Extend android.app.Application.

In your manifest, your application tag refers to the class that
should be constructed for the Application.   It's usually left to
be the default, Application, but you simply name your Application
extension class there, and Android constructs your class instead of
the default.  It gets its own onCreate()/onDestroy() lifecycle that
spans all activities.

Clarification:  Application has no onDestroy() and you can't rely
on the onTerminate() either.  Android can kill a process without
notifying the Application class instance, so if anyone adds other
features besides the singleton pattern, take care in holding onto
any kind of resource that needs to be committed/saved/closed/freed
for a clean termination.  In fact, better if you don't hold any
such resource open/uncommitted at all, if you can help it.

You are creating a MediaPlayer instance.  You save a reference to
this instance with your variable mp.  You then start the music
by calling one of the methods, with mp.start().  You then forget
all about the instance, by not saving any reference to it.  The
local variable mp is gone, but the instance is still playing.

This is like sitting in your car, starting the motor, turning on
the radio of your car, then stepping out of your car as it rolls
away from you.

You should declare mp to be a member of your class, instead of a
local variable.  And at an opportune time, such as during your
activity's onPause() callback, you should use the member mp to
control the media playback.

If this makes no sense to you at all, I'm afraid you should go
find a much more basic introduction to Java and software
development in general.

[android-developers] Re: reflection

[Hari Edo]

Reflection is the act of asking the JVM (Dalvik VM) and the
current ClassLoader object instance for information about the
classes it can reach in memory or along the Java CLASSPATH.

It has nothing to do with inter-process communication.  If it
is not in the current process, or reachable by the CLASSPATH,
it won't be found.

On Android, different package names are given different user
ids, and apps reside in completely different directories, to
further limit the visibility of files related to a different
application.

 Presently, inside getView of the Gallery Adapter, we are making use of

If you do find yourself making many calls, especially from the same
name multiple times, form your own MapString,Integer with each
value you look up.  Use the value if it's already in the map, or
ask Android to resolve the name and add it to the map.  This
technique is called memo-izing or memorizing the function.

[android-developers] Re: Getting rid of the blink after a TranslateAnimation

[Hari Edo]

Note that the usual matrix-manipulating animations don't change the
hit-testing for a view, so you have to actually move the real view
if you plan on animating a view that is touchable.

My app, Qwiz - Hiragana, uses a LOT of drag and drop of views,
and touchable views that move around on their own initiative.

I implemented a true Animation class that adjusts the view's
position instead of manipulating the drawing transform matrix.
Then you don't need to reinvent the wheel of timing and iterating
and interpolating things (and you can use all of the other fun
iterators to bounce or wiggle the view).  I use a FrameLayout to
support moving things around by their margin coordinates, instead
of an AbsoluteLayout, but the idea is the same.

 Has anyone tried doing the translate themselves with AbsoluteLayout?
 It looks like I'll have to duplicate the translate functionality by
 using a Handler to act as a run loop and move the View myself? A
 handler isn't a separate thread right? I just use it to to call a move

[android-developers] retrieve current shadow effect attributes from a textview

[Hari Edo]

I can set shadow layer attributes in XML for a textview.
Separate attributes control the Dx, Dy, radius and color.

I can also set shadow layer attributes in code.
One method will allow me to set all four of those parameters.

However, I don't see any getters for these parameters.

I'd prefer to design the appropriate shadow in XML, but
I guess I'll have to do it in code, so I can know the values.

I was hoping to read the existing values of the parameters,
so I could do some dynamic effects with them in some
situations, without completely shifting to implement the
parameters in code.

(Example:  rotate text view upside down, but play with
shadow Dx Dy so the lighting doesn't look wrong.  Or
animate shadow right to left as another graphic moves.)

[android-developers] How to intercept when the application is brought to foregroud from background

[Hari]

Hi,
Out Mobile Application required the user to provide username and
password to login. After login, if the user navigates to another
application and tries to come back to our application again, i would
like to intercept this action and redirect the user to login screen
and then lead to where ever he was before.

How can i achieve this?

Currently we are doing it a very crude way by tracking the user's
action in variables and in onResume() we check for the value of the
variable and make a decision if he should continue or be redirected to
login.

Is there something to the order of an Interceptor which can use tell
me if the application coming to foreground was actually in the
background and not a new process.

Any assistance is appreciated.

Hi Mark,
Thanks for validating our approach.

If you are called with onResume() and not onCreate(), you are coming
back onto the screen after having not been on the screen.

There are 2 possibilities,
1. you come back to the same screen (activity) due to the application
flow. Navigate to other activities and come back to it due to
application functionality.
2. you come back after you navigate away to another application.

Is there a way to recognize this using the application attributes or
context attributes.

  flashes on the screen before disappearing

  2) I can't by trial and error try to find all the different ways user
  could cause soft keyboard to be shown and override all corresponding

[android-developers] Re: Where to report app update problems?

[Hari Edo]

I ran into this on an update of my free app tonight as well.
I completely quit the whole Chrome browser process (which has
been running for a month), and restarted it.  The price problem
went away as if by magic.

I did notice another problem, where non-latin characters were
causing the Recent Changes text to blank out.  It would let
me type them and save them, but then a refresh or look in the
Market would show no text at all.  If I latin-ized the text,
it worked okay and the Recent Changes text stayed.


The question of the thread still stands:  where do you post
this kind of problem with the market, officially?

[android-developers] Re: Application Shutdown

[Hari Edo]

Save data when the user's no longer interacting with it.  And even
when they are.  As you point out, there are no guaranteed callbacks.
The system assumes that if you're idle, you can be killed.

 Not really sure where to put the global app shutdown code:

 In Application.terminate() ?:  Not really guaranteed to get called.

 In a service?:  I have n services.

 In an activity? : ok but just for the view data.

 The only thing I can think is to have a service dedicated to this

 really want to start a service at a time when my app is getting
 shutdown perhaps for resource consumption.

 Perhaps one could  just let each component deal with it, however I
 have shared data/state (that is not a preference) across the

 the application (subclass) should be dealing with application global

Given that in-app purchases can have immediate benefits to the

[android-developers] Re: Force Close Question

[Hari Edo]

Something else is causing your Force Close.  Read the exception
report in LogCat and dig into the actual cause.

Read up on the Activity lifecycle, in particular the bubble
that reads Other applications need memory:

http://developer.android.com/reference/android/app/Activity.html

The Android OS won't even try to return to your app if
it reaped it for memory.  It will just restart it.  There
is no way that it reaps some part of the app state
irretrievably, but leaves the process going.

If the system is low on memory, your app may receive an
*opportunity* to shed some of its state data at the app's
discretion.  If your app does honor this *request*, then
the system may have regained enough memory to allow the
user to run some other heavy task in the foreground.  The
current activity also got an earlier courtesy notice when
your activity was no longer active, giving an opportunity
to save the state away.  If your app does not honor these
requests, or cannot free up enough memory, the then the
system reserves the right to completely kill the whole
process as a whole.  If that happens, your next startup
will surely be as a brand new process, and your activity
will be handed whatever you chose to save away earlier.

You *can* flag your app to start at the initial activity
every time the app is suspended and resumed, but that is
completely separate from your impression that Android
frees up memory without any notice or control over its
own state.

 Is there a way instead of resuming the app that has freed memory and will

 Is there a setting in the Android Manifest to force start brand new if freed

[android-developers] Re: How to convert a image into Base64 string?

[Hari Edo]

This kind of question seems more like a school homework
assignment, but in case the question is practical, here goes.

What Base64 is:

  http://en.wikipedia.org/wiki/Base64

This article gives plenty of examples and details that someone
can write their own fully-tested implementation in an hour.

But in twenty seconds of using Google, I tried the search string
of base64 encode in java and got tons of hits.  The third link
has a fully-tested implementation (based on the same Wikipedia
example data and algorithms).

  http://www.wikihow.com/Encode-a-String-to-Base64-With-Java

Now, it's not good form to just copy code without asking, but
since this is a How-To article published on the web, I don't
think you'll run into copyright issues if you adapt their code
into your application.  There's good discussion in the article
about how the code works, and advice on learning to program.

However, this question is even sillier than that.  The
Android platform even includes a class called Base64 which
does all the encoding and decoding for you.  Without
worrying about incompatibility, testing, or license issues!

  http://developer.android.com/reference/android/util/Base64.html

That class even has an .encodeToString() method that turns
your arbitrary byte[] data into a String ready for use in
sqlite TEXT fields.

Beyond that, I'm really not sure what the actual problem is.

I'm not trying to be rude, but it's depressing when people
ask questions that are so quickly answered with even the
most cursory search first.

[android-developers] Re: How to convert a image into Base64 string?

[Hari Edo]

Perhaps the actual question is how to get a byte[] for a given
Bitmap or vice versa.  This is, indeed, Android-specific and not
as obvious as the Base64 part of your question.

However, again, with a couple minutes of Google use, I found
this snippet:

 // have Bitmap bitmap from somewhere
 ByteArrayOutputStream bos = new ByteArrayOutputStream();
 bitmap.compress(CompressFormat.JPEG,100,bos);
 byte[] array = bos.toByteArray();
 // now have byte[] array to use, e.g., base64 encode

And then on the decompression side,

 // have byte[] array from somewhere, e.g., base64 decode
 Bitmap bitmap =
BitmapFactory.decodeByteArray(array, 0, array.length);
 // now have Bitmap bitmap to use, e.g., to make a drawable

[android-developers] Re: Absolute path for an asset file

[Hari Edo]

An APK file, like a Java JAR file, is really just a ZIP
archive file with special manifest data included with the
other data files.

Your assets/ directory on your development machine may
contain individual files.  They get zipped up into the
APK along with all the .class, .png and .xml files.
The APK file contains it all in one file.

Once inside the APK, there really is no absolute path
to the files inside.  They are not really files.  They
are just entries in the ZIP, which a zip expander could
reconstruct into real files later.

This is why you use special API to access assets.  Many
apps ship with initial databases, and if the app finds
no existing file, it uses the special API to reconstruct
real files (sometimes confusingly called copying a file
out of the APK).

See copyDataBase() in this article for a working
example of how to extract an asset and reconstruct a
file in your data directory.

[android-developers] Re: Suggested Android Phone for Unity Game Development Testing?

[Hari Edo]

They list compatible phones.  Buy one of those.

This is the most important paragraph I found in your forum link:

  The problem is, publishing to Android won't really be
  solid for another year. Consumers get locked into 2 year
  contracts, in the same way I got locked in, and the most
  common will be the free phones and the cheaper (50$) for
  the next 2 years. Without a way to dumbdown your app, or
  modify the published one within Eclipse to work for ARMv6,
  that is potentially a GIANT chunk of current market share
  which will be LOST to a UnityAndroid developer.

The market has a ton of very competent devices out there, but
Unity is not doing what they need to do to be compatible
with what is out there NOW.  As much as a developer may want
to tease over the specs to find 'Samsung Galaxy S' is a
compatible model, the general public does *not* see any
clear differentiation or tiers.  They just see that your
game sucks because it won't run while Angry Birds does.

That, and Unity has no try ON THE PHONE before you buy
plan to get into Unity development.  You might go with the
trial on your desktop, but that doesn't really tell you
whether your idea will work well on the Android platform.
If you had to buy Eclipse and the Android SDK just to load
an app on your own phone, we wouldn't have come so far so
fast.  If the price of those tools was as high as Unity,
come on now.

[android-developers] Re: Tablet support up to 2.2

[Hari Edo]

I think the tablets in general will be more likely to flip orientation
and good apps should handle that gracefully.  But I think they should
also have a lock orientation control at the OS or hardware level,
as it's common but annoying to have the view flipping as you lay down
in bed reading on an e-book reader (as an example).

One thing that I did in my app was to identify some views as heros
and some views as mere interface details.  I made a generic sizing
capability which makes a view, say, N% of the size of the whole
window, and I use that on all the hero elements.  So the buttons stay
the same size (finger sized) but the main elements of the screen use
their available real-estate more fully.

 (Not to toot my own horn, but see my Qwiz - Hiragana screenshots.)
 http://www.appbrain.com/app/qwiz-hiragana/cc.halley.droid.qwiz

Other applications just try to allow the additional area to be used
as a more convenient tableau, fitting more items in view at once,
because the individual items remain finger-sized.

[android-developers] Re: One frame buffer per activity or one frame buffer per the whole system

[Hari Edo]

I'm not sure that this is the right forum for platform-developers;
it's more geared to app-developers.

However, I will point out that there's an important entity between
the framebuffer level and the activity level, and that is the Window.
Activities come and go, Dialogs come and go, and their views are
attached to the window to be seen.  Activities themselves aren't
users of pixels, but Views are.  I don't think any storage is given
to a View; the View is merely consulted to render into the Window.

On a phone, the Window is basically 95% of the whole screen so you
don't necessarily think of this, but it's still a separate entity.
I could definitely see some more traditional WIMP implementation
offering a Desktop that contains multiple overlapping or tiled
Window areas, and in those Windows various Views/Activities being
managed in parallel.  Not saying that's the best vision of a huge
display on Android, but it may help understand the framebuffer
question you posed.

[android-developers] Re: Edittext max characters - not set max

[Hari Edo]

I think Andre was looking for a design limit, not how to set one.

The control can handle many pages of text, even with spanning styled
markup.  The EULA which I saw on one Android tablet was shown in a
simple text view, and it was about fifty pages of text on the tablet.
(The EditText control should have the same limits as the TextView,
as the EditText is just some additional features on the basic view.)

The answer is how much memory can you allocate?  Of course
the system needs to allocate resources to measure and typeset and
render all of that text.  If it's too long, consider showing the text
in pages or chunks.

[android-developers] Re: performance when passing background data to ui thread

If you're sure that all users of the data are within the same process
(the
same app), then using Java synchronized is the best way to go.
However,
you will need to be very careful to understand your semaphore
dependencies,
or deadlock will occur.  Not responding is almost as bad as Data
corrupted due to bad inter-thread communication.

The use of Bundles and/or ContentProviders are to enable inter-process
data
passing, and to avoid some of the danger of errant deadlock
situations.

 Hi

 I've got an app that spawns of a seperate thread. Parses JSON data into a

 well with my previous XML parser, as XML parses data while it downloads. But
 JSON doesn't (atleast I haven't found a way to get that working). In either
 way the JSON data is much smaller and much faster to parse.

 I've recently added a feature that requires me to load several sources of
 json in parallel, parse in the background, and pass all the data back again
 using a Handler. This is a bit slower than I was hoping.

 Would it be faster (and possible) for me to do this:
 BackgroundThread extends Thread {
     onCreate (Parent) {
         this.parent = parent;
     }
     onData {
         parent.addParsedData(x);

 I'm thinking this won't be thread safe, as ListAdapter is in the parent

 Should I instead inside the listadapter (which puts data in an array) have
 synchronized access to it's items?

[android-developers] Re: ENHANCEMENT: Allow java public static finals to be referenced from XML

[Hari Edo]

It would create a dependancy loop:

 *   the app code requires R.java to be generated
 *   the R.java generation requires the XML to be scanned
 *   the XML @java would require the app code to be scanned

Maybe you intend the XML to be scanned twice, with two different
sets of rules as to what is allowed to be broken on each pass,
such that nothing broken slips through the two passes.  On the
first pass, find @+id kinds of things to add to R.java; on the
second pass, find @java kinds of things to validate the code.
All of the rest of the XML DTD rules would need to be covered
on at least one of those passes.  That kind of duplicity is
very error-prone and troublesome.

 Now an IDE can provide completion on these @java variables, and the
 IDE can also immediately flag undefined references. Also, the
 definition of the authority string can be changed in one place, and
 the code does not break.

 Is there any reason this would not work -- it seems like the benefits
 offered are significant.

[android-developers] Re: Application does not use all screen in Android tablet (with android 2.2)

[Hari Edo]

The tarot deck answers nothing, so I'm reading the tea leaves now.  If
that
doesn't work, I will throw some chicken bones across the campfire.

What app?  Is this your app?  What are you doing to develop the
activity?
Are you making layouts in XML?  Did you try a sample application?
What
tablet are you talking about?

I'm sure this reply is not useful to you.  Google for How to ask
questions
the smart way and you may get some more useful replies.

 Hi List,

 In a phone, the application works o, but in an android tablet (with android
 2.2) it does not use all screen, does anybody know how to fix that?
 I just see the application in the center of screen, and the rest of screen
 is black.

 Thanks a lot!

[android-developers] Re: Built-in resource unexpectedly not found

[Hari Edo]

 I would recommend that developers depend as little as possible on
 explicitly using firmware-defined resources. If you need them, copy
 their values into your project. Or, at least have a value that you use
 as a fallback in case a firmware-defined resource is not available.

While I understand that sentiment, it's not practical.  Widgets
like Button constantly use built-in firmware-defined resources.
And I too have gotten TWO crash dumps where the .inflate() failed
unexpectedly, one trying to fetch Button's .9.png background, and
one trying to fetch a custom .9.png that I had put into my own app,
just as you suggest doing.

Now my first guess was that I was doing something wrong with a
timer, some accidental UI Thread/Worker Thread collision, so I
did revise that area of the code.  But if it wasn't that, then
I am not sure exactly how you should really respond to an
exception deep in .inflate() or .setContentView()... besides
calling .finish() and let the user wonder why the activity did
not appear.

[android-developers] Re: Hide each view after LayoutAnimation

[Hari Edo]

Are you setting fill-after to true on this animation?

 I have a GridView with several n Views in the Layout.  When one is

 everything is being removed.  Once the animation ends I do something,

 My problem is that once the LayoutAnimation on each view is complete
 it returns to its original position.  This doesn't give me the affect
 I am going for.  Is there anyway to keep the Views from returning
 until after the activity is started?

[android-developers] Re: android: a redundant UI syntax ?

[Hari Edo]

This is pretty common with XML systems with a lot of tags, especially
if they're meant to be expanded or mashed up.

If you create your own View types, you can extend the XML DTD to
include
your namespace.  Third-party libraries can add all of their features
with their own namespace.  It's the combination of these namespaces
and
DTD rules that allow the XML scanning process to find errors or
mistyped
parameter names.  No namespace, weaker protection from errors.

 Hi,
 I am a beginner to android development and wanted to ask a question to
 the developer community.

 What is the significance of specifying android: in front of every
 attribute.?

 be it view or layout, I know that I am already in android, then I feel
 its kind of redundant to prefix an attribute with android colon.

 TextView android:id=@+id/mastersname
 android:layout_width=wrap_content
                 android:layout_height=wrap_content android:text=Master of
 Computer Applications
 /TextView

 Cant this be expressed as follows?

 TextView id=@+id/mastersname layout_width=wrap_content
                 layout_height=wrap_content text=Master of Computer 
 Applications
 /TextView

 However the one reason that I can think of is specifying the package
 name (android:) as a prefix to resource will help to retrieve the
 resource easilly. But still, this need not be prefixed in every
 attribute. This should have been able to be specified in only one
 header or similar at the top.

 I think this might help in bringing down the code size and also for a
 quicker parsing.

 Let me know if I am missing something.

 Thank you

 Further,
 the attributes itself also can be very well shortened.
 ex:width as w height as h and layout_width as lw and
 layout_height as lh

 Thank you,
 Naren P

Read the documentation for the 'adb' tool.  Live pictures from your
phone or from your emulator.  No video.

[android-developers] Re: how to get home screen click event

[Hari Edo]

As far as I know, the Home button can't be overridden or hooked by
your application.  The button invokes an Intent, and the system looks
up what activity (or activities) are coded to respond to that Intent.

All your app will know is that it is asked to save instance state,
pause operation, and maybe get a notice that you're being destroyed.
