[android-developers] Problem related to multiple Screen Support

[swaps12]

Hi,

I am trying to develop an app for which I want multiple screen
support. I have read the Android article on Best practices for
Multiple Screen Support. As per the article we have to follow 3
important things
1. Mention support for different screen sizes(large, medium and small)
and any density in AndroidManifest.xml.
2. Place images of 3 dpi's (120, 160, 240) in 3 folders res/ldpi, res/
mdpi and res/hdpi.
3. In layout's the dimension should be mentioned in "dip" units. Then
Android will take care of the scaling on its own.

I have implemented all these points in my project. The images are
picked up correctly from the appropriate folders. But the arrangements
of the controls in not same.
e.g. I ran the app on three emulators
1. Resolution 240*320 dpi 120.
2. Resolution 240*320 dpi 160.
3. Resolution 240*320 dpi 240.
(All the emulator have same resolution but different density. )

The problem is the position of the controls is not same on all the
three emulator. As per my understanding if the
android:layout_marginLeft and android:layout_marginTop are mentioned
in "dip" then this problem should not occur. As the density of the
emulator increases the controls get placed more towards the right.

Is it necessary that i provide layouts for all combinations of
dimensions and density i.e. in layout-small, layout-large, layout-
medium, layout-long,layout-notlong?

Am I missing some important point? Any help will be great.
Thanks.

private int imageCounter = 0;
private int index_count = 0;

//in oncreate i have done something like this:
public void onCreate(Bundle savedInstanceState)
{
setContentView(R.layout.frame0);//this one is the common parent
layout for all imageviews
super.onCreate(savedInstanceState);
imageView = new ImageView(this);

ImageButton next = (ImageButton) findViewById(R.id.next);
ImageButton back = (ImageButton) findViewById(R.id.back);
next.setOnClickListener(this);
back.setOnClickListener(this);

//show the default image
this.loadImage(imageArray[0]);

}

in onclick something like this:
int imagePath = 0;
// TODO Auto-generated method stub
switch (v.getId())
{
case R.id.next:
if(imageCounter < 25)
{

imagePath = imageArray[index_count];
}
index_count++;
imageCounter++;
break;
case R.id.back:
if(imageCounter > 0)
{
//imagePath =
}


break;

}

this.loadImage(imagePath);
//now i have loadImage method to load image into imageview

[android-developers] Re: Camera Callback onPreviewFrame

You should not rely on frame rate or exact timing of preview frames.
AFAIK they are not guaranted.

[android-developers] Detect language of text

[alan lam]

i am writing a dictonary apps.

i have some problem, hope here have some advance level developers to
help me.

1.  i want to detect the language of text
like i have a string a = "japanese"
pass string a into a function, return the language.
japanese than japanese,
english than english.
PS

is there any api or internal function i can use?

2. have you use any electronic dictionary before.
in the past , i can control the screen easily by lower level language.
i can highlight some word than cross search another dictionary.

but now what i can do is,
i have a button to turn on something.
then the user can highlight some word,
then the apps will copy the highlight word,
then user click the cross search button.

what i want to do is.
the user dont need to click button to turn on this function.
they can directly highlight the word then click the cross search.

Regards

I am not sure about this. But I guess, you will have to override the default
long click action and drop in your Custom context menu there and handle the
events.

Re: [android-developers] Re: issue with Edit Text

[Kumar Bibek]

Yup, Even I guess, it's a problem with eclipse's layout editor. It doesn't
render some things properly. On the device, it should work fine. It should
work fine on the emulator as well.

[android-developers] Re: Inflate layouts with different density

Hey,

Have you been able to solve this problem? Cos I am stuck with a
similar problem and I dont like the idea of having different .xml

file in /layout folder be useful for multiple screen with different
resolutions and density.

[android-developers] Updated procfg.txt

[Zsolt Vasvari]

I had to add a couple of entries to my procfg.txt.  These are not
specific to my app and should really be part of what Google recommends
as the default configuration.


The first line excludes all classes that derived from Preference as
these are referenced by name in the preference screen configuration
XML documents:

-keep public class * extends android.preference.Preference



The other one excludes the Parcelable creator which is special class
and probably found via reflection by Android:

-keepclassmembers class * {
public static android.os.Parcelable$Creator CREATOR;
}


Hope these are useful for some developers.

[android-developers] From emulator to real device

[kypriakos]

HI all,

I can run the app on the emulator without issues - when I run it on a
real device
I get the exception that certain classes are not found (see below for
exception).
I am sure this is a loaded question and I know an emulator is not a
real device
and many things can alter their behavior during this transition but
loading classes
seems a bit fundamental - any ideas? Perms and everything else in the
corresponding
directories are identical. I am just wondering if anyone else has
seen  similar
issue before and if they have any hints as to what to look for -
thanks again

Hi Bob Kerns,

I'm not using any browser dependent code in my application, I'm just
sending the request from the business logic.

Hi catalin Braica,

The length of the content that am getting is -1, The server is ours
only, so I asked the server persons to look into the logs what exactly
logged, They informed that
there is nothing logged, Is there any chance for android to change
url, because, the same url is working on desktop.

Possibly better / easier but probably not faster, but there are various HTML
parsers out there that will parse HTML and make it easier to transverse.
Just google for Java HTML parser and you'll find a few.

 However, all icons that are part of the SDK can be found in:

 $ANDROID_HOME/platforms/$SDK/data/res

 where $ANDROID_HOME is wherever you unpacked the Android SDK and $SDK
 is some platform version (e.g., android-8).

 If the icons you seek are not there, then try http://source.android.com
 .

Re: [android-developers] Finish multiple tasks (stacks)

[Dianne Hackborn]

You can't do this without programmatically getting all of your activities to
call finish() (possible using CLEAR_TOP to reduce some of that), implying
that they may need to be re-instantiated to be able to do so.

What you are trying to do here isn't really how tasks are supposed to work.
 The whole point of them is that they are entirely separate, unrelated
things (basically applications).

[android-developers] Stop AlarmManager sending past repeating alarm.

[Henrik Lindqvist]

When the device awakens from sleep state the AlarmManager sends all
"missed" alarms. Can I prevent this from happening, grouping past
alarm to a single intent instead?

There is an intent extra "android.intent.extra.ALARM_COUNT" which
seems to suggest it's possible?

Correct. If you catch the unhandled exception yourself, none of the
automated stuff (force close dialog, etc.) kicks in. It is up to you
how to deal with it. I'd always try reporting it, assuming you're
hooked up to a system to do that. After that, the strategy is up to
you: just continue along, finish()/stopSelf() the offending component,
System.exit() to blow away the process, etc. Similarly, it's up to you
how you inform the user about what transpired (dialog, toast,
nothing).

[android-developers] Re: "Local" Service vs "Remote" Service

[William Ferguson]

Sorry, I may have muddled several concepts here .. I'll blame lack of
sleep.

I was thinking that a RuntimeException force closes an app and that
there is limited opportunity to capture the failure (pre Froyo) before
the app is destroyed.

But if using Thread.setDefaultUncaughtExceptionHandler() actually
stops the force close then there is opportunity to dispatch the crash
report since the app won't be destroyed. Whether the crash dispatch
happens in the app process or another process is irrelevant.

And yes, I was only imagining having the 2nd process exist briefly.
Something like an IntentService solely tasked with dispatching the
crash and handling disconnection and other dispatch failures. But that
doesn't seem as relevant now.

Am I back on track?

I don't know where you read that. PendingIntents have been able to
start services since the beginning.

I am a bit nervous about how WakeLocks work when starting a service
directly versus going through a BroadcastReceiver, but otherwise
AlarmManager starting services works like a champ. It's great for app
widgets, if you have an IntentService that is doing the updates and
you are controlling the update schedule yourself rather than using

I have no idea what "the standard power control widget icons" are.
However, all icons that are part of the SDK can be found in:

$ANDROID_HOME/platforms/$SDK/data/res

where $ANDROID_HOME is wherever you unpacked the Android SDK and $SDK
is some platform version (e.g., android-8).

If the icons you seek are not there, then try http://source.android.com.

Your strategy only makes sense if you feel that your "failed process"
will be able to successfully do IPC to start a service to report the
exception and *not* successfully be able to report the exception
itself. I am dubious that this is the case. If your process truly is
failed, neither will work. I think both will work, in which case why
add the overhead and complexity?

In the end, though, this isn't a huge deal...*if* your proposed

a 2nd process briefly is one thing -- having a long-lived service
chewing up a 2nd process is another matter entirely. We still have too

The process is not in a bad state. Some piece of your code is in a bad state.

The process will not be destroyed, because your code is running and no
components have been destroyed. The UI is no more a factor for
reporting an unhandled exception than it is for anything else.

I cannot disagree more.

There is no failed process.

[android-developers] Re: "Local" Service vs "Remote" Service

[William Ferguson]

Mark, as I noted above, the reason I think a remote process is a valid
solution here is to ensure that the crash info is actually sent. I
wouldn't rely upon the failed process to send that data.

I presume that is what the Froyo Exception logging (to Market) does,
but perhaps it just wings it.

[android-developers] Re: "Local" Service vs "Remote" Service

[William Ferguson]

Forgive if I have this wrong, but I thought the report button only
shows for Froyo and beyond.
I certainly don't see it on 2.1 on my GalaxyS.

If its for reporting the crash to oneself (as it seems to be - to
handle all Android versions), then handing it off to another process
to send the data to a remote site seems to be a practical solution,
rather than relying on a process that is already in a bad state and is
trying to destroy itself. That way the process that is responsible for
sending the crash info can handle all the flows associated with a
remote connection without being constrained by immediate destruction
or UI responsiveness.

[android-developers] Re: French character encoding issues

[Bob Kerns]

Note that what Android documents as the behavior (including dependency
on a system property) is just one form of "you don't know what it will
do". The standard Java behavior is documented thus:

"Constructs a new String by decoding the specified array of bytes
using the platform's default charset. The length of the new String is
a function of the charset, and hence may not be equal to the length of
the byte array."

"The behavior of this constructor when the given bytes are not valid
in the default charset is unspecified. The CharsetDecoder class should
be used when more control over the decoding process is required."

Note how loosely-specified "the platform's default charset" is, and
even when Android narrows the behavior somewhat, it still leaves you
not knowing what to expect "file.encoding" to be set to, and what you
might break if you dared to change it!

This is indeed something that was a gaping flaw in the early history
of Java that they cleaned up later, in JDK 1.1. Which was a very long
time ago, but it's still causing problems.

I could never figure out what planet those hibyte variants originated
on. On ours, there is no way to use them to produce any correct
behavior, that isn't a completely useless special-case hack.

[android-developers] Finish multiple tasks (stacks)

[raukodraug]

Hi everyone,
I have an app that contains multiple tasks (stacks of activities).
I can jump from one to another with no problem, but when i finish a
task it goes to the previous stack. I would like to finish all stacks
whenever i finish one of them, because I want my application to
finish.
Does anyone have an idea on how to achieve this?

Cheers,

Re: [android-developers] The onConfigurationChanged is not getting called when changing the orientation from portrait to landscape

If you are relying on string values changing for landscape vs. portrait, I
would strongly urge *not* using android:configChanges, and just letting your
activity be restarted.

[android-developers] Failed to fetch URL: https://dl-ssl.google.com/android/repository/repository.xml

[ida]

Hi,

My dev. machine is uBuntu where the SDK starter package is installed.
Eclipse 5.2 is running.  When I tried to download the rest of the SDK,
from within the Android SDK and ADT Manager menu, I got the "Failed to
fetch URL" problem.

My target H/W is a Real6410 reference board running Android 2.1 (no
plan to upgrade to 2.2 soon).  It looks like I'd choose API level 7 to
match my target system.  Is Eclipse 5.2::SDK v?::ADT 0.9.9 a safe
combo to use?

Appreciate any suggestions/hints you may have for a beginner!

[android-developers] Animating different views during the same animation

[gontran]

Hello,

does anyone knows if it's possible to animate different views during
the same animation:
I have a linear layout containing 6 dices (each dice extends a
textview) and I need to animate each dice to simulate a roll (each
dice will rotate on itself).
I know how to do this rotation on each dice by using 6 animations, but
I want to group these animations in one, so that I would be able to
add an animation listener to execute further instructions at the end
of this animation. I tried with an animationset but didn't manage to
do it.

Thank you by advance.

regards,

Gontran

[android-developers] Download finished with wrong size

[Dale]

So far, I have been getting this error for every package. Only a few
packages have loaded with one or fewer retries.
- Documentation for Android SDK, API 8, revision 1
- Samples for SDK API 8, revision 1
- Samples for SDK API 7, revision 1
- Usb Driver package, revision 3
- Market Licensing package, revision 1

I've tried dozens of times to download "SDK Platform Android 2.2, API
8, revision 2" with absolutely no luck. I have no ability to change
proxy settings or even disable antivirus (as other sites have
suggested).

On the other hand, I can directly download the zip files using firefox
with no problem at all from 
http://dl.google.com/android/repository/android-2.2_r02-windows.zip.
I have, however, noticed that it can take upwards of 15 minutes to
start the download, the download doesn't proceed for long periods of
time and then downloads the entire file in about a minute.

I have no idea what "the standard power control widget icons" are.
However, all icons that are part of the SDK can be found in:

$ANDROID_HOME/platforms/$SDK/data/res

where $ANDROID_HOME is wherever you unpacked the Android SDK and $SDK
is some platform version (e.g., android-8).

If the icons you seek are not there, then try http://source.android.com.

[android-developers] The best way to download webpage and parse it into simple UI

[SHADOW-XIII]

I am just starting developing first app and not sure which way is the
best fit for my needs.

The key is to download a page source, get small part of it and display
it using Android UI, with possibility to submit it later as a form
action.

The simplest way would be probably to ditch UI and go with WebView
however I decided to parse it into UI, so no WebView for me.

Currently I am trying to download page source using org.apache
packages (from SDK Wiktionary simplified sample) and parse it using
some regex (this will give me known incompatibilities when website
changes layout but I am willing to go this way).
Question is: is there a better/faster/easier way to pull the source of
webpage (or part of it)?
Or I will have to stick to org.apache due to the fact I want to submit
a form based on user selection)?
Maybe someone got a hold to more source code examples of similar app ?

[android-developers] The onConfigurationChanged is not getting called when changing the orientation from portrait to landscape

[sambit]

Hi,

While working on orientation change I have found that the
onConfigurationChanged is not getting called when changing the
orientation from portrait to landscape.But when I am changing from
landscape to portrait the method is getting called.
Is it the correct behavior because the onConfigurationChanged should
by called whenever we are changing the orientation.
(android:configChanges="orientation")?

I have also found one strange behavior or error, When we are changing
from  portrait to landscape orientation the string value is displayed
correctly(automatically by android system) but when in am changing the
orientation from landscape to portrait the same string is
displayed(i.e the string in landscape mode).The expected behavoiur is
the string id specified in the portrait mode should be displayed.Is it
an platform bug or something worng in my code/programming.


Wait for the response.

Regards
Sambit

I think OSX is better than windows for android development.
(OSX doesn't have to install cygwin, and easy to convert iPhone

[android-developers] Parsing response of a WCF webservice under Android?

[Wolkenjaeger]

I need to consume a WCF webservice via SOAP under Android. I am doing
this by using KSOAP2.5.2. Now as we are not allowed to edit the WCF in
any way, I am currently not able to change the output which the WCF
service returns. That is my main problem. To solve the problem, I need
to take what I get from the WCF (workaround):

anyType{schema=anyType{element=anyType{complexType=anyType{choice=anyType{element=anyType{complexType=anyType{sequence=anyType{element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{};
 }; }; };
element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{}; }; 
}; };
element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{}; }; 
}; };
element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{}; }; 
}; };
element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{}; }; 
}; };
element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{}; }; 
}; };
element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{}; }; 
}; };
element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{}; }; 
}; };
element=anyType{};
element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{}; }; 
}; };
element=anyType{}; element=anyType{}; element=anyType{};
element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{}; }; 
}; };
element=anyType{}; element=anyType{}; element=anyType{};
element=anyType{simpleType=anyType{restriction=anyType{maxLength=anyType{}; }; 
}; }; }; }; }; }; }; }; };
diffgram=anyType{DocumentElement=anyType{CL_9_2_4_DestInfo=anyType{DESTINATION=
plus LOTs of other data.

Now, as it seems this is some Microsoft propretary code which is in
fact a full dataset/xsd(?) How can I parse this thing into a working
dataset or at least make it somehow readable to my little Android?

[android-developers] passing data between views

[mannyk]

Hi,

I am trying to create an app with two view classes - portrait and
landscape. I use the portrait view in my layout.xml and use the
landscape in layout.xml under the layout-land folder.

My both view classes (portrait and landscape) are essentially the some
bitmap placement differences. My end goal is - to fetch some pictures
in these classes and manipulate them before displaying. I obviously
don't want to refetch the pictures on orientation change, so would
like to pass bitmaps between these views. Is that possible? Here is my
first iteration of one of these view classes and for now I am just
trying to pass an integer between classes.

My Main Activity is like this:

public class flipperActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState)
{
super.onRestoreInstanceState(savedInstanceState);
}
protected void onSaveInstanceState(Bundle outState)
{
outState.putBoolean("bs", true);
super.onSaveInstanceState(outState);
}

And my View class is like this:

public class FlipperVerticalView extends View
{
String time;
Paint paint = new Paint();
private Bitmap[] pictureArray = new Bitmap[5];
int i = 0;
boolean forward = true;
public FlipperVerticalView(Context context, AttributeSet attrs)
{
super(context, attrs);

paint.setColor(Color.BLUE);
paint.setStyle(Paint.Style.FILL);
paint.setAntiAlias(true);
GetPhotoClass getPhotos = new GetPhotoClass();
pictureArray = getPhotos.GetPhotoArray();
this.setOnClickListener(new OnClickListener()
{
//change picture index here
});
}
@Override
protected void onDraw(Canvas canvas)
{
super.onDraw(canvas);
canvas.drawBitmap(pictureArray[i], 20, 20, paint);
}
/***SaveState/

@Override
public Parcelable onSaveInstanceState()
{
Parcelable superState = super.onSaveInstanceState();
SavedState ss = new SavedState(superState);
ss.stateToSave = this.i;
return ss;
}
@Override
public void onRestoreInstanceState(Parcelable state)
{

SavedState ss = new SavedState(state);
super.onRestoreInstanceState(ss.getSuperState());

this.i = ss.stateToSave;
}
static class SavedState extends BaseSavedState
{
int stateToSave;
SavedState(Parcelable superState)
{
super(superState);
}
private SavedState(Parcel in)
{
super(in);
this.stateToSave = in.readInt();
}
@Override
public void writeToParcel(Parcel out, int flags)
{
super.writeToParcel(out, flags);
out.writeInt(this.stateToSave);
}
public static final Parcelable.Creator CREATOR =
new Parcelable.Creator()
{
public SavedState createFromParcel(Parcel in)
{
return new SavedState(in);
}
public SavedState[] newArray(int size)
{
return new SavedState[size];
}
};
}
/
***EndSaveStateCode***/
}

}

[android-developers] Camera Callback onPreviewFrame

[Maurizio Mento]

Hi,
I am working on an application in Android and I have to manipulate the
data coming from the preview.

I read that the default frame rate is 15fps.
I measured the time from one call of the onPreviewFrame function and
the next one and I noticed that I got different times depending on the
size of the preview (at the moment no other operations are done in
this function).
How can it be possible?
I thought it would be called at any frame so 15 times in a second
(approximately every 66ms) independently of the previewFrameSize.

Can someone help me please?
Thank you!
Maurizio

[android-developers] How to embed youtube video on mobile site to allow android device to see the video

[StErMi]

Hi everyone.
At the moment I've developed a mobile version of my site using jQTouch
( jQuery framework for mobile ).
It works perfectly on iphone and android devise with touch, slides,
and so on.
The problem is when I need to show to the user a youtube video.

On ipod touch/iphone i simply put the html5 embed code of the video in
the page and show to the user. Then it will load normally.
If I do the same thing with android devices it will show a black
iframe and nothing more...
What can I do?
How can I do the same think done by http://m.youtube.com ?

Anyway the mobile site i'm talking about is: http://www.sc2vod.eu
I've tested it with Android Emulator :)

[android-developers] About Surface.setMatrix

[xamous]

Hi There,

I'm trying the Surface.setMatrix api, however, it acts not same with I
expected when I rotate the matrix.

The code looks like:

matrix.setRotate(degrees, width / 2, height / 2);
matrix.getValues(tmpValues);
Surface.openSession();
surface.setMatrix(tempValues[Matrix.MSCALE_X],
tempValues[Matrix.MSKEW_X],
tempValues[Matrix.MSKEW_Y],
tempValues[Matrix.MSCALE_Y]);
Surface.closeSession();

The usage is extracted from WindowManagerService.java.

Can anyone explain the four parameters of Surface.setMatrix (float
dsdx, float dtdx, float dsdy, float dtdy)?

Thanks a lot!

[android-developers] Calculating correct location on a resized background bitmap

[Kirgan]

Hello,

Been learning Android over the last 2 months. I am currently working
on an game that is a turn based board game. It currently has a main
layout that uses a spinner and an adapter to pull a list of saved
games out of a sqlite db. It also has a new game function that stores
initial game settings in the db. I have now moved on to getting the
initial board and player controls drawn when a new game is started or
when a saved game is selected.

I first learned to create the board with standard drawLine & drawRect
commands. I used the width and height in onSizeChanged to calculate
how and where to place each part of the board. This method works great
for all screen sizes. I can calculate exactly what controls a player
touches or what squares a player touches.

But I am no artist, so if figure if I want better graphics I will need
to hire someone to create bitmaps for me, instead of just drawing the
board.

My question about doing this with bitmaps is that since I need to
calculate exactly what area of the board has been touched - both for
specific player commands and to know what square to put the piece in,
how do I calculate that with using bitmaps when there are so many
screensizes that the bitmaps will be scaled to. For example, I watched
a Google I/O 2010 video where it showed an example of how a bitmap
would be scaled and although you can prescale the width and height to
whatever you want, the actual pixels for say a "boarder" may end up
being 2 pixels wide or 4 pixels wide or 1 - depending on the image and
how the system scales it. But for my game, I would need to know
exactly how wide the boarders are, their location and exactly where
each square block is on every screen resolution in order to know what
area has been touched.

So, far everything I have found just shows how to scale bitmaps and
used the three standard densities in the drawable directories. What I
wonder about the drawable directories is if I created three sizes for
different densities wouldn't the system just scale it to a different
size anyway sometimes, because there are more than 3 screen sizes out
there. From what I read there used to be 5 and now there are even more
with the tablets.

I would appreciate it, if someone could point me in the right
direction to learn how to calculate specific locations on a background
bitmap (in this case a background board game) no matter what
dimensions the bitmap is resized to.

Thank you,

--Mike

Re: [android-developers] Re: Downloading Problem

[Catalin Braica]

Hello

Shouldn't you be testing for the HTTP status code ? Just a quick example:
you can get zero-byte content in case of a redirect from the part of the
server (3xx status code). In this case I see there is a flag to
automatically follow redirects (HTTPUrlConnection.instanceFollowRedirects),
but I don't see that you set it.
But in all cases you need to test the HTTP status code.

Just my 2 cents

Re: [android-developers] AppsLib (Archos store) is not legit?

[Raymond C. Rodgers]

A few months ago, I received a notice out of the blue that my app was 
being included at AppsLib and that I could click a link to manage the 
application at their site. They apparently skimmed some apps directly 
from Android Market to build their library, and then retroactively 
contacted the authors to invite them to use AppsLib. It took several 
days of me trying to contact them (during which I watched as my app went 
through their QA compatibility verification process), but they pulled my 
app when I explicitly told them they didn't have permission to use it on 
their site or system.


At this point, I consider them just barely more legal than pirates.

Recently we found that they are distributing pirated software,

We have contacted AppsLib several times, and Archos directly twice,

We had AppsLib in our list of markets to release products into once

What's your experience? Is this unusual for that store, or is this

[android-developers] Indeterminate ProgressDialog Spinner Stops

[Dan]

Hello all,

The spinner in my ProgressDialog appears to stop spinning for the
duration of the task I'm doing, I am using a 2.2 emulator. What can I
do to avoid this stop to make the application look like its not
frozen?  This is the code i'm using:

 private class NetworkTask extends AsyncTask{
private ProgressDialog progress;

@Override
protected void onPreExecute() {
progress = new ProgressDialog(OuterActivity.this);
progress.setIndeterminate(true);
progress.setMessage(getText(R.string.progressText));
progress.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progress.show();
}

@Override
protected Void doInBackground(Void... params) {
performLongNetworkOperation();
return null;
}

@Override
protected void onPostExecute(Void result) {
OuterActivity.this.listAdapter.notifyDataSetChanged();
progress.dismiss();
}
}

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

[Warren]

I am optimizing a game for performance. A large part of the screen
remains the same from frame to frame and it takes a while to render,
so I intend to use glScissor() to limit new drawing to only certain
parts of the screen. I do not do a
gl.glClear(GL10.GL_COLOR_BUFFER_BIT); so the bits that were drawn
previously should remain.

This provides a large speed increase and works very well on the Droid
and on the emulator. However, it is not working on the G1 or Droid
Eris, both made by HTC. The areas outside the scissor region are still
being drawn over in a strange way. It's as if what's being drawn
inside the scissor region is being wrapped outside the region. There
is a large rectangle in the middle of the screen that has the correct
contents. This is the defined scissor region. Immediately below the
scissor region is a row, maybe 150-200 pixels high that looks like an
exact copy of the bottom of the scissor region.

Again, this only is happening on the HTC phones.

I believe that unless I specifically clear the color bits, they should
remain from frame to frame. Is this correct? Any ideas? Is this an HTC
OpenGL library bug?

Thank you,
Warren

[android-developers] Starting a service in another applicaion

[kl4232]

I have 2 applications. The first is a standard activity with a "start
service" button. The second is a service only application. It has no
activity. It does have a receiver which listens for the BOOT_COMPLETED
intent.

After I've installed both applications on my handset I run the first
app. When I press the "start service" button on the first app, I'd
like to send an intent to the second app to starts its service.
If the service was part of app1, I could create an intent like this...
startService(new Intent(this, MyService.class));... and the service
would start. But MyService is part of another application so I cant
use MyService.class, in app1.
I've tried creating an intent like this in app1
Intent i = new Intent();
i.setClassName("com.backgroundService", "MyService ");
startService(i);
but the service doesnt start.
What information do I need to put in the intent to start a remote
service?
Do I need a receiver associated with the service to handle the intent
and start the service? If so, what ACTION and  CATEGORY do I use in
the services manifest for the receiver?
Thanks for your help

Yes, ResultReceiver seems really nice - it's more lightweight than a
broadcast intent, and requires less "wiring" both in the manifest and in the

IntentServices are awesome. I haven't used ResultReceiver yet, though.
I have just used android.os.Messenger in an IntentService, and that
works nicely.

[android-developers] Evaluate javascript value on WebView, Android

[filiz_gokce]

hi, I open a webview page that page have

var addToBasketDisabled=false; var iPhoneStatus=""; function
GetStatus() { return iPhoneStatus;//Master Pagelerde tanımlı } var
path = "http://www.yemeksepeti.com/App_Themes/Default_tr-TR/images/
IPhone/"; function PreLoadDisabledButton() { var image = new Image();
image.src=path + "Iphone-button-ekle-pasif.png"; } function
DisableAddButton() { addToBasketDisabled= true; var buttonObject =
document.getElementById("ctl00_AddToBasket"); buttonObject.src = path
+ "Iphone-button-ekle-pasif.png"; } function EnableAddButton()
{ addToBasketDisabled= false; var buttonObject =
document.getElementById("ctl00_AddToBasket"); buttonObject.src = path
+ "Iphone-button-ekle.png"; } function OnAddButtonClick()
{ if(addToBasketDisabled) { return false; } DisableAddButton(); var
validateValue= ValidateInput(); if(!validateValue)
{ EnableAddButton(); return false; } } PreLoadDisabledButton();

these javascript When I press a button on the webview I have to read
the "iPhoneStatus" value and close the webview screen and decide the
result.

I wrote these codes in my .java class

 mWebView = (WebView) findViewById(R.id.webview);

WebSettings webSettings = mWebView.getSettings();
webSettings.setSavePassword(false);
webSettings.setSaveFormData(false);
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setJavaScriptEnabled(true);
webSettings.setSupportZoom(false);

mWebView.setWebChromeClient(new MyWebChromeClient());

mWebView.addJavascriptInterface(new DemoJavaScriptInterface(),
"demo");

mWebView.loadUrl(feedurl);
final class DemoJavaScriptInterface
 {

  DemoJavaScriptInterface()
  {
  }

  public void clickOnAndroid()
  {
   mHandler.post(new Runnable()
   {
public void run()
{
 mWebView.loadUrl("javascript: GetStatus()");
}
   });

  }
 }

 final class MyWebChromeClient extends WebChromeClient
 {
  public void onCloseWindow(WebView window)
  {
   window.destroy();
  }
  public boolean onJsAlert(WebView view, String url, String message,
JsResult result)
  {
   Log.i("log ", message);
   result.confirm();
   return true;
  }
 }

But it never go in the onJsAlert method, is there any way to evaluate
the value of GetStatus()

Thanks

Re: [android-developers] Re: Controlling a service

[Federico Paolinelli]

I was looking to existing source code to get some inspiration, and I
came across the google io 2010 schedule app.

They still use an intent service to perform the calls, but they use
another way to fetch the result of the webservice interaction, which
is sending to the intent service a parceled ResultReceiver to be
called to be notified of the result.

I am not sure that this approach is better compared to returning the
result bundled in a broadcast (any ideas?), but in any case I think I
will go with the intent service in order to save some resources.

[android-developers] Re: ADT painstakingly remove my exclusion setting for android library

[Bob Kerns]

Do you have Subclipse (Eclipse's Subversion plugin) installed?

If not, install it. It should solve your problem, if the .svn entries
are being copied into the bin/ directory from elsewhere.

Also, if you have not added the bin directories to svn:ignore on the
parent, do so now, then delete the bin directories from Eclipse. They
should *never, ever* be checked in.

In general -- if you have a .svn directory in your bin folder, you
should figure out how it got there, and stop it from happening.

This should never involve any exclusion settings in your Eclipse
project. That should be completely unnecessary.

[android-developers] Re: How are credentials stored in the OS framework?

[Bob Kerns]

This considerably overstates the issues around rooting. Rooting does
not give arbitrary code arbitrary access. It does give the user (or
whoever rooted it, perhaps the corporate IT department) the ability to
run arbitrary code of his choosing with arbitrary access. On my phone,
I am prompted to grant such access.

That's as a general statement. Specific techniques of rooting may open
up more, and introduce other issues. But rooting can enhance security,
too, by allowing you to impose controls that otherwise would not be
possible.

If you're serious about security, write your own authenticator, based
on certificates and a PKI infraststructure, and if needed, a second/
third factor, e.g. a password (never stored or transmitted) and an
auth token with a reasonably short timeout, and a onetime token
generator device.

There's not much you can do to protect against a user being held up at
gunpoint while accessing your system, but you can protect against lost
phones (revoke the certificate on any compromise, good password, and
keep that token generator separately from the phone).

Those factors come at a cost of usability. Maybe we'll see biometrics
capabilities built into future devices. Maybe the camera and
microphone can even do the job..

[android-developers] Restricted location in publisher GUI is not working on some devices

[Chister Nordvik]

We have an application that is restricted to one country (Norway). But
I am sitting here with multiple devices, HTC Wildfire, SE XP10 (after
2.1 upgrade) and SE XP 10 Mini (after 2.1 upgrade) that fails to find
the application even though they are registered on a Norwegian network
(Tele2). The SE devices found the application before they got the 2.1
upgrade, and I have lots of other devices (Nexus One, HTC Desire, HTC
Tattoo, Galaxy Tab) that finds the app without any problems.

This is very important for us since we can't enable the app worldwide
due to copyright issues, so is there any way to resolve this issue? Is
it the operator or the Android device that fails to report the correct
country here?

Any help would be greatly appreciated.

The documentation for that callback says to call getItemAtPosition to
get the item clicked.  What it doesn't tell you is that this is a
method on the AdapterView given to you in the parent parameter and you
need to pass it the position parameter.  The Adapter associated with
your view will then be queried to feed the object of interest back to
you through this method and you can check it to see if it's a group or
a item.

I have no idea what "the standard power control widget icons" are.
However, all icons that are part of the SDK can be found in:

$ANDROID_HOME/platforms/$SDK/data/res

where $ANDROID_HOME is wherever you unpacked the Android SDK and $SDK
is some platform version (e.g., android-8).

If the icons you seek are not there, then try http://source.android.com.

Re: [android-developers] Getting ready to Publish

[Kostya Vasilyev]

I've not used ant for my builds, but...

If you are prompted for the password, and you see ant run zipalign, then 
it looks like you're all set.


You can further test this by trying to install your .apk with adb:

adb install 

Just make sure to first uninstall the debug version of your application, 
or you'll get a signature conflict.

Hi,

I'm just about ready to Publish my application. I have a question
about the Signing/Aligning of the application.

In looking at the Android documentation they say to run "ant release"
to compile the application in release mode. Then to sign and align the
apk run "jarsigner" and "zipalign".

I had used "android create project" to create my build.xml. I modified
it to run proguard.
I find that when I run "ant release" it appears that signing is done
as part of the process (I'm prompted for my keystore password) and the
apk is zipaligned.

I guess I'm confused that the documentation makes it 3 steps, "run ant
release" then jarsign, then zipalign. BUT, my "ant release" seems to
do everything.

Is the documentation not upto date?  Is it safe/acceptable to just run
"ant release"?

TIA

Re: [android-developers] Re: French character encoding issues

[Kostya Vasilyev]

Good catch, Bob.

You are right of course - I missed the lack of encoding parameter in the 
second call.


The docs say this:

http://developer.android.com/reference/java/lang/String.html#String(byte[])

Converts the byte array to a string using the default encoding as 
specified by the file.encoding system property. If the system property 
is not defined, the default encoding is ISO8859_1 (ISO-Latin-1). If 
8859-1 is not available, an ASCII encoding is used.


Looks like the encoding is quite likely to be single-byte based, this is 
implied by the choice of ASCII (not UTF-8) as the fallback.


Then there is the deprecated "public String (byte[] data, int high)", I 
see it as a failed attempt to fix things in a simple, but incorrect way.


Overall, it looks like the designers of Java did not push for proper and 
consistent use of character encodings across the board when the language 
was still young.


Over time, though, the Java standard library evolved to make consistent 
use of encodings, because only that is guaranteed to give correct results.

System.out.println("UTF-8 decoded: "+new String(rawData,"UTF-8"));

*D/FileUtils(  485): Default decoded: hockey,march�,football*
I get the same issue if I change the locale of my phone to French

[android-developers] Re: Is it a UNIT Test or an Integration test?

[Bob Kerns]

You can and should write normal unit tests for everything in your app
that doesn't depend on the Android-specific APIs.

It's a good idea to try to keep the android-specific stuff and the non-
android-specific functionality as separate as possible. Not only does
it aid testing, it aids porting to other platforms (say, a companion
desktop app, or migrating some of the functionality to a server).

I'm not entirely happy with what I've come up with so far for running
android-specific unit tests on the platform (emulator or device) as
part of an automated build procedure. But running non-android tests in
the JVM as part of the build gets you a lot of the benefit -- how much
I think will depend on the nature of your application. An app that's
all forms and no function (say, a data entry app) will probably derive
relatively little benefit from the non-Android test -- and even little
benefit for the Android-specific ones. Integration and UI testing may
be where most of the testing benefit is to be found.

A calculator app with a simple UI but a lot of functionality, could
benefit greatly from standard JVM-based unit testing.

If you want to get a response from Samsung, you might have better chance

That would be a question for the media/press relations department at
the device manufacturer in question. For relatively-traditional media,
such as a newspaper or blog, stuff in a vendor's press area works
fine, but that doesn't appear to be your intended use. However, they
would be a fairly likely starting point to try to figure out what the

If you have some sort of co-marketing deal with a device manufacturer,
image licenses like the ones you seek are probably part of that
arrangement.

Re: [android-developers] nest custom views

[Kostya Vasilyev]

Kavitha,

If your intent is to let the user drag and drop game pieces from the 
bottom portion of the screen to the game grid, then:


Implement a view that subclasses ViewGroup (possibly one of its 
subclasses, such as RelativeLayout or LinearLayout). Handle touch and 
drag events in that view.


Specify a transparent background for this view group so it's invisible, 
and put your current views inside this one.


This is how you can implement drag-and-drop that crosses the boundaries 
of individual views.

I wouldn't discard issues with the operator - quite the opposite, since

Eclipse, now gives me the timeout all the time, mean while the
emulator works perfectly, so I think we can discard an Operator Issue.

Hi, I have two phones (Motorola Milestone) and I has developed a
simple application that does some network operations using web
services, the applications runs perfectly calling a method on the
emulator and in the phones, but just in one of the phones, in the
other one i always get a "operation timeout exception".
I have checked the network configuration in the 2 phones and is
identical, and the two phones has the same operator with unlimited
network plan, Im little lost here, and I dont know what else to check
or try.
If anyone has an idea or a possible explanation to this behavior, I
will appreciate your help.

[android-developers] Re: Downloading Problem

[Bob Kerns]

I don't know what's happening to you specifically, but I do observe
this behavior with regular web browsers and certain broken web
servers. The server will get an error, either consistently or
occasionally, and fail in such a way that the browser just sees a
close.

If there's no Content-Length: header, the browser has no way to know
that the content has been truncated.

So if the web server is under your control, I'd suggest making sure
the Content-Length: header is set (and set correctly).

The other observation I'll make is you're copying the data a byte at a
time. This will be far slower than allocating a byte array as a
buffer, and copying a buffer at a time. It shouldn't make a difference
in behavior. Just be sure to pass the returned length from the
read(..) call (if not negative) as the length to the write(...) call.
