[android-developers] not able to create image and save resized image except the type Bitmap.Config.RGB_565

[Honest]

i have made simple application which load image in canvas scale it
according to screen height and width and after that user can write and
draw something on it using his finger and once user complete its
drawing. He should be able to save it. But i have to save the image as
same width and height as original image.(not according to phone screen
size). So i am scaling the image to its original height and width. But
it is only able to scale if i use Bitmap type Bitmap.Config.RGB_565 as
it uses law memory(but very poor quality). For others type like
Bitmap.Config.ALPHA_8, Bitmap.Config.ARGB_ it is giving
MemoryOutOfException. The code to re size image to its original width
and height is as follow.

public Bitmap getResizedBitmap(Bitmap bm, int newHeight, int newWidth)
{

int width = bm.getWidth();
int height = bm.getHeight();
float scaleWidth = ((float) newWidth) / width;
float scaleHeight = ((float) newHeight) / height;

// create a matrix for the manipulation
Matrix matrix = new Matrix();
// resize the bit map
matrix.postScale(scaleWidth, scaleHeight);
// recreate the new Bitmap
BitmapFactory.Options options = new BitmapFactory.Options();
options.inTempStorage = new byte[16*1024];
//bm.
//BitmapFactory.decodeByteArray(bm.getRowBytes(), 0, length,
opts)
Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width,
height,
matrix, false);


 //  return Bitmap.createScaledBitmap(bm, newWidth, newHeight,
true);
return resizedBitmap;
}
The following is code to create blank bitmap on which i draw the
content which is in my view and then i try to resize it.

Bitmap b = Bitmap.createBitmap(view.getWidth(), view.getHeight(),
Bitmap.Config.RGB_565);

The main problem with Bitmap.Config.RGB_565 is the quality of image is
very poor compare to original image which has very good quality. so i
want to use Bitmap.Config.ARGB_ if possible. any suggestion and
advise is more then welcome.

[android-developers] Hide Phone Number in the Dialer

[mwllace]

Im using  and intent to invoke the default dialer and automatically
call  phone number stored in my application. Everything works fine,
but the number is visible in the default dialer UI. I need to display
something else in place of the number like "My Special Number". The
behavior would be much like when a user dials a number already stored
in contacts, where the name of the person is visible and not the
underying phone number.

I am able to update the call logs so they read "My Special Number"
when my app dials this number, but this is only after the phone is
hung up.

This is the way I update the Call Log:

values.put(CallLog.Calls.CACHED_NAME, "My Special Number");

Is there a similar method for writing to the default dialer when the
call is initiated?

Thanks for any pointers you can provide!

[android-developers] URI-escape

[bob]

I'm looking at this WebView function:

public void loadData (String data, String mimeType, String encoding)
Since: API Level 1
Load the given data into the WebView. This will load the data into
WebView using the data: scheme. Content loaded through this mechanism
does not have the ability to load content from the network.
Parameters
data
A String of data in the given encoding. The date must be URI-escaped
-- '#', '%', '\', '?' should be replaced by %23, %25, %27, %3f
respectively.
mimeType
The MIMEType of the data. i.e. text/html, image/jpeg
encoding
The encoding of the data. i.e. utf-8, base64


I just noticed the "data must be URI-escaped".  Is there a function
for this?

Why do you say that MediaPlayer does not support rtsp?  I ask this
because it does support rtsp.  It's documented.  The audio/video
format of the stream still has to be supported by the device, though.

Quite right. Sorry, thought this was on a different list.

Your previous question asked how other apps that report this data do
it. That is only loosely tied to how you as a developer testing your
own app on your own equipment would do it. What is workable for a
developer in a lab is not necessarily something that is
production-grade and should be foisted upon unsuspecting users.
Unfortunately, there are too many lousy engineers who can't tell the
difference, or their ego is yapping too loudly in their ears to just
go use those techniques anyway, risks be damned.

With respect to RAM, Ms. Hackborn's post on SO that I linked to
previously will help you measure this, and much of her post is about
developer tools (e.g., using adb).

With respect to CPU, for any single device that you are holding in
your hand, if you can run top or can get raw stuff out of /proc/,
those should be valid.

With respect to battery... well, that's a pain to measure. If you
don't show up on the "battery blame screen" (usually off of Settings >
About) after you've been running for many hours, users probably will
not complain about your battery consumption. For more details than
that, you either gotta shell out for a Qualcomm MDP (around $1,400),
or try to get PowerTutor or the equivalent to work for you, or tear
apart a phone and figure out where to hook up leads for a wattmeter,
or something.

Ahh, ok, thanks.  I was wondering if it was something like that,
but I wasn't quite ready to make that (educated) guess.  :-)   So when
developing a live wallpaper, for example, and getting advice to check
its usage of RAM, CPU, and battery, there is no valid way of doing so,
and the advice is therefore equally invalid?  Or is even an approximate
number on those valid?

Re: [android-developers] Re: one AsyncTask at a time

[Dianne Hackborn]

I wouldn't trust that not to have a deadlock.  Not to mention sitting in a
tight loop polling is pretty wretched.

If the desire is: "I want to execute whatever is the most recent operation,
dropping any before it," then my general solution is to have a pointer to
the most recent operation, schedule the work for it when first setting it,
and when that work is done checking to see if there is another operation to
execute and starting again if so.

That way as you create new operations while the first one is running, you
just drop any that haven't started yet.  And when the last one that was
started running is done it will start execution of whatever was the last
thing you wanted to happen.

Try launching the Web browser. If the Web browser can get to the
Internet, then one of your other two presumptions is faulty.

[android-developers] Re: How to deal with expensive view height calculation?

[blake]

Tedd,
  I'm quite sure that you don't want to do any of this in onDraw.

  It's just a thought, but suppose that measureHeight, in addition to
remembering the width it had just returned, kept a number that
represented the error in that width.  When it returns, it requests a
re-layout, unless that error is small.  That would allow you to avoid
the second thread altogether... a thread that is, surely, going to be
hard to manage over your Activitiy's lifecycle.

[android-developers] Re: Got the Bluetooth blues: Service Discovery Failed

[darrinps]

I have two text books that cover Bluetooth and have read multiple
articles and not one has mentioned the need to do that.

What I read in the documentation is that the UUID is random:

"A Universally Unique Identifier (UUID) is a standardized 128-bit
format for a string ID used to uniquely identify information. The
point of a UUID is that it's big enough that you can select any random
and it won't clash. In this case, it's used to uniquely identify your
application's Bluetooth service. To get a UUID to use with your
application, you can use one of the many random UUID generators on the
web, then initialize a UUID with fromString(String)."

Are you saying that there is some sort of table that exists that
specifies my exact device?

Re: [android-developers] Modules similar to DLLs in android

[Michael Banzon]

The JAR files are a standard Java thing - google'ing it should give
good resources.

The process have nothing to do with the final Android app - you deal
with all the magic in Eclipse or your favorite development env.

Google "Android Plugins" or something - many apps do this.

Check out Android Library Projects in the documentation.

Note that in the former case you're talking about *dynamic* linking while in
the latter you're talking about *static* linking.

It has to be in a conditional test ie:

 // you can call any function defined only  since   or 
greater.

[android-developers] Why is the default to use dpi instead of screen size for drawables

[ArcDroid]

Directories are already created for ldpi, mdpi and hdpi, but it
appears that normal, large, xlarge work much better for tablets and
phone sizes since some old phones fall into the mdpi bucket.  why is
the default to use dpi instead of screen size?

Thanks,

Thanks Michael

I'm not sure I'm going to use the Android Market, and I'm guessing I

Do you know of any tutorials  (or care to share)  how to create a jar 
file and then link/include it inside an activity ?

Yuck.

Use a LinkedBlockingQueue and your own thread working jobs off of that
queue, rather than AsyncTask.

[android-developers] Autoreload of Webview

[Jay Bloodworth]

At my work, I have to access an intranet site several times a day. The
site has a short session inactivity logout - shorter than the frequency
with which I must access it - so I end up having to relog every time.
I'd like to write a small Webview app to just to a reload every ten
minutes or so to keep me logged in. What's the best way to implement the
reload trigger? Separate thread? Service? I'd like to maintain the
session when the ui side of the process is backgrounded or even killed,
if possible.

Thanks,
Jay

[android-developers] Is there some APIs to monitor the RAM/CPU utilized by another app?

As title.

I have two apps.
One app should monitor how much CPU and how much RAM is consuming the
other app.

Is there some API to do that?

Re: [android-developers] Modules similar to DLLs in android

[Michael Banzon]

I haven't actually tried to see if it's possible - but I suppose you
could make an application with no activity for the launcher.

The main problem I see is distribution - how do you get users to
install the program package from Android Market?

I make a few programs that share functionality and I've bundled this
in it's own project and include the JAR-file in the projects that need
it.

[android-developers] Re: hiding keyboard after button press

[sblantipodi]

to make it work on every phone you should delay the softInputMode only
once the keyboard is compeltely visible.

something like this really help that much:
Timer timer = new Timer();
timer.schedule(new TimerTask() {

@Override
public void run() {
InputMethodManager imm = (InputMethodManager)
getSystemService(INPUT_METHOD_SERVICE);

if (imm != null) {
 
imm.hideSoftInputFromWindow(input.getWindowToken(),
0);
}
}
}, 100);

But I don't know if 100milliseconds is enough for every phone/tablet.

[android-developers] Modules similar to DLLs in android

[New Developer]

Hi All

Is there a mechanism to create the equivalence of DLLs so that one can 
create modules.


It's not quite an apk, can't be run by itself,  it must be called from a 
main.apk.


and this main.apk will scan looking for these modules and based on what 
is or is not present

will then have a certain set of functions and functionality ?

just asking

Thanks in advance

This is not surprising.

No. The parent window doesn't have the keyboard in the first place.

Use:

InputMethodManager
imm=(InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);

imm.hideSoftInputFromWindow(v.getWindowToken(), 0);

where v is the EditText that has the input method editor open.

That might be true for data members (never tried that), but it is
definitely not true for methods. You cannot load a class that refers
to a method if that method does not exist -- you will get a
VerifyError.

[android-developers] request for an interview

[Lela Mose]

Dear group members,

Please take a minute to read this request for an interview.

My name is Lela Mosemghvdlishvili, I am a PhD candidate at the Erasmus
University Rotterdam (
http://www.eshcc.eur.nl/english/personal/mosemghvdlishvili/) and for my
research am interviewing App developers.

The interview takes about 20 minutes and is an informal chat (typing) in
Skype or Google Talk, where I will ask you to share your experience about
app development, when and how did you start as well as which platform you
prefer.
As a participant you will receive the summary of my findings first, before
it gets published.

Looking forward to talk to you!
Feel free to reply to this email, or contact me through skype  or Google
talk (for both platforms my username is lelamose)


best  wishes,

Lela

[android-developers] Finding if softkeyboard is open in an alertdialog.

[sblantipodi]

Hi,
is there a way to detect if the softkeyboard is opened from an
alertdialog?

The alertdialog is shown upside my canvas.
If I call the getHieght() from the canvas once the alertdialog is
shown and the softkeyboard is shown, I get always the same height (the
full screen one).

[android-developers] Textview from thread

[Kristoffer]

Hello.

I have been searching for answer how to update a textview from another
thread, i have found several answer that point to using "Handler" but
i dont know how i should implement that in my code, maybe you could
point it out for me.

Iam checking if the user is logged in or not to Twitter,
here is my code.

SettingsActivity.java

public void updateLoginStatus() {
Thread f = new Thread() {
public void run() {

final TextView loginStatus = (TextView)
findViewById(R.id.loginstatus);
loginStatus.setText("Logged into Twitter : " +
TwitterUtils.isAuthenticated(prefs));

}

};
f.start();
}

and here is the code in TwitterUtils.java

public static boolean isAuthenticated(SharedPreferences prefs) {

String token = prefs.getString(OAuth.OAUTH_TOKEN, "");
String secret = prefs.getString(OAuth.OAUTH_TOKEN_SECRET, "");

AccessToken a = new AccessToken(token,secret);
Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(Constants.CONSUMER_KEY,
Constants.CONSUMER_SECRET);
twitter.setOAuthAccessToken(a);

try {
twitter.getAccountSettings();
return true;
} catch (TwitterException e) {
return false;
}
}


any good idees?
Thanks

[android-developers] Re: Publish modified APK to the Android Market without triggering an Update to existing users?

As I told you in my previous answer :

Trying to upload an apk with the same or lower version number from the
current one will only give you an error message.

It will not break anything. It is actually one of the few thing that
doesn't break in the Android Market.

If you are afraid to try it for yourself and you don't seem to want to
hear it from us, then it is going to be hard to end that thread. So I
repeat :

YOU CAN NOT DO THAT BUT IF YOU TRY IT WILL NOT BREAK ANYTHING.

Loud and clear ?

:D

[android-developers] how to blit a row of a bitmap as fast as possible to the canvas?

[Marco Alexander Schmitz]

Hello,

Id like To take a row of a bitmap and paint IT To The canvas, as fast
as possible, and over and over again. This is going to be a retro
effekt... how can this be done? I rather dislike the idea of a for
loop which paints from the bitmap e.g. 480 times.

Thanks for advice,
Marco

Re: [android-developers] Re: How reliable is Google Marketplace Device Compatibility Report?

It would crash on Android 1.x only, since starting with 2.0 the classloader

No need to use reflection for that kind of test if the target is Android

[android-developers] one AsyncTask at a time

[bob]

So, I have a bunch of buttons and each one launches an AsyncTask.

So, should I keep a variable like this:

AsyncTask currentTask=null;

Then should I do

if (currentTask != null)  currentTask.cancel();

before I launch the new task?

I only want one task running at a time.  Right now, if someone monkeys
with the buttons, they get a bunch of tasks running simultaneously
with weird UI results.

Check that the pointer returned to you when  you allocate memory is

close to the memory limit, though, you're doing something very wrong.

[android-developers] OutOfMemory exceptions

[bob]

How do I tell how much RAM my MetroPCS LG Optimus uses?

I keep getting OutOfMemory exceptions.  Also, what is the most user-
friendly way to handle OutOfMemory exceptions?  Right now, the app
crashes.
