Re: [android-developers] Issue with screen layout in 3.2

[Vector-Code]

There does appear to be a scaling problem of some sort. Here are some 
screenshots. First, the app running in the 3.1 emulator:

This is how the layout should render, with the subview in the lower right 
corner, sized to about 2x3.5 inches.
 
Next, the app running in the 3.2 emulator with compatibility mode. An 
interesting side note: I originally targeted API 4 to insure compatibility 
down to 1.6. In order to get the xlargeScreens tag, I had to change my 
target to API 9 but running the app with this target, even without the 
xlargeScreens tag (or any "supports-screen" tag for that matter), I got no 
compatibility button. I had to change the target back to API 4 to get the 
Compatibility button. Here's the 'shot:
 

Note the stretching of the subview, though the size of the edittext in the 
background has not changed. Next, we have a shot of the app with the 
xlargeScreens tag (and the API 9 target):
 

As you can see, the app has layed out exactly as it did when compatibility 
mode was enabled, even though the xlargeScreens tag has been added, however, 
the compatibility button is no longer available.
 
Here is my manifest for the last shot:
 

http://schemas.android.com/apk/res/android*
**package=*"com.vectorcode.vTypeNotes"*
**android:versionName=*"0.8.0.0"* android:versionCode=*"10800"*>

[android-developers] Re: KeyEvent ACTION_DOWN + ACTION_UP fire immediately

[Halsafar]

It seems if I change the IME to anything but the ASUS Keyboard one
then everything is fine.  Consistently though if I change to the IME
type of the ASUS Transformer dock this problem occurs.  Breaks games
that rely on key down and up event coming in properly.

[android-developers] Re: For a good time...

[gjs]

Hi,

Thanks for that. Between (3) & (4) do you need to establish a
bluetooth connection with the Trackpad and interpret its data stream,
perhaps mapping that to something related to what an activity might be
displaying ? Or does Android 3.2 do this i/o for you - automagically
treating the Trackpad as a type of mouse/pointer/touchpad peripheral
device ? And what about coordinate mapping between the device and
screen ?

No, exceptions shouldn't be used as a program flow control mechanism,
which is what your example is.

Re: [android-developers] Re: popupwindow

[Dianne Hackborn]

Abstract classes and interfaces both have their downsides:

- Abstract classes don't allow multiple inheritance, resulting in an
explosion of tiny classes.
- Interfaces tend to result in a hard to maintain framework because it is a
lot harder to introduce new functionality (can't add a new method with a
default implementation for old apps).  Plus not being able to have
convenience functions can make the interface version less useful.

Also the inability to have default implementation in interfaces makes it
more annoying in places to control what appears in the SDK, since we can't
use our @hide tricks or else third party apps can't implement it because
they can't implement the needed hidden methods.

I go back and forth between the two.  I think I have settled on interfaces
for small little things with one or two methods (callbacks like all the
things on ListView) and abstract classes for larger protocols.

One thing I am sure of, however: protected sucks.

[android-developers] KeyEvent ACTION_DOWN + ACTION_UP fire immediately

[Halsafar]

I am finding whenever I press a key down on a keyboard it immediately
fires both the down and up events.  It seems with the virtual keyboard
or a real keyboard in the case of the EEE Transformer Pad this is
true.  Is this the expected behavior or am I doing something wrong?  I
have tried with both the dispatch and separate onKeyDown/onKeyUp
events.  Both give same results.

Note this is not true for special keys.  CTRL for example fires
properly and its repeat count properly goes up as you hold it.  Where
if you hold a regular key like "A" it fires up/down events
simultaneously and the repeat count stays at -1.


 public boolean dispatchKeyEvent(KeyEvent event)
 {

  if (event.getAction() == KeyEvent.ACTION_DOWN)
  {
 Log.d(LOG_TAG, "onKeyDown(" + event.getKeyCode() + ", " +
event + ")");

 return true;
  }
  else if (event.getAction() == KeyEvent.ACTION_UP)
  {
  Log.d(LOG_TAG, "onKeyUp(" + event.getKeyCode() + ", " +
event + ")");

  return true;
  }

  return super.dispatchKeyEvent(event);
 }

Re: [android-developers] Re: How to know what internal process runs an application

[Dianne Hackborn]

A string is useful to be able to look at the process information in the
debugger, and the most common use for this is to have multiple .apks share a
process to run in (not run parts of a single .apk in multiple processes), so
a string provides the ability to do scoping and generally not go insane.

[android-developers] is the Main dictionary available for app/IME word prediction?

[Saied]

Hello,

I am hoping that Android's main dictionary can be accessed by apps and
IMEs  to that the same main dictionary and user dictionary is used to
give a consistent word prediction response to users.

Is this so? Or is it the case that each app should create and manage
its own main dictionary?

If it's the latter, then that would be regretful since it's going to
create a lot of waste, not to mention divergent UI.

AFAIK, there is no official solution for migrating from paid to in-app
billing model. There probably should be one.

Theoretically, it should be possible to use the LVL to check the license
status. Then, when they run the new freemium version (using IAB), if they
had already bought the old paid one, you could give them the license
automatically. However, the Android market apparently doesn't currently
allow the CHECK_LICENSE permission on free apps. To do something
similar, you could have your own database of users who bought the
paid version, and have your free app phone home on first run. It might
be a PITA if you have a lot of paid users, but it should be doable by
exporting the data from the merchant console.

Re: [android-developers] Re: Dynamic Accordion Creation in android

[Jatin D Patel]

Mark,

Thanks for your reply. I learnt something new from it.

Firstly i was not aware of ExpandableListView?
Secondly on doing a small research, i guess i can have more control on child
component (adding components in child view) via my blog, if compared with
ExpandableListView (which have good controls on list based items).

OK, not wanting to start a flame war, but that's not true.
If you know how to use checked Exceptions then they are a boon. Same
for unchecked Exceptions.

The problem lies in developers and APIs making very poor decisions
regarding their usage.


To answer Zsolt's question:

A checked Exception needs to be either dealt with or rebadged to fit
the paradigm of the calling class. If it can't be dealt with and your
class is now in a non-functional state consider rebadging it to an
unchecked Exceptions such as IllegalStateException.

An unchecked Exception should generally only be caught (if then) at
the very top of the process hierarchy, such as from a Thread that
needs to ensure that it doesn't fail inappropriately. Otherwise they
are best left for the UncaughtExceptionHandler to deal with (which
normally means your app crashes and whatever error reporting channel
is in place is invoked).

[android-developers] Re: Offering free and paid APKs on the Market

[keyboardr]

The only problem I could forsee is the stuff that would normally be
handled as a managed purchase.  Namely: the reinstall issue.
Scenario: purchased old version, uninstalls app, downloads new
version.  In this case the app should be installed with the unlock
complete, but it won't be without some effort.  Ideas on how to catch
this edge case?

[android-developers] Communication between android app and application on a remote server

[work_84]

Hello,

I am developing an Android application which has to send/receive data
to/from a remote server securely.
The Android application has to authenticate the server and the server
needs to authenticate the device. The data sent/received should also
be encrypted.
I have implemented similar feature on desktop applications using
OpenVPN and thrift(Since the server is in C++ and the client in java).
I was planning to use the same on Android but am not sure if openvpn
package is available to be used by android applications.

Any suggestions on this will be very much helpful.

Thanks

[android-developers] Using expanded option menu as default menu style

[erkangur]

Hi,

I was wondering if it is possible to use expanded option menu as
default menu style instead of six-tab style with a more button. I
encountered this[0] conversation which has last message sent in 2008.
I could find neither any positive comment on the web nor a reference
from api docs about that. Is there any way to overcome this problem,
or should I ask this as a feature?

[android-developers] Keep list item in a list view vertically centered (non touch based devices)

[photon]

Hi,

I need to achieve Scenerio as in the previous thread:
http://groups.google.com/group/android-developers/browse_thread/thread/17a76edb78471115#



1) ListView has many items (i.e. scrolling will occur at some point)
2) At the beginning, the selection is at the top (item #0)
3) User scrolls down (i.e. we're not in touch mode)
4) For the first items, the selection is moving down without the list
to scroll.
5) Once the selected item is reaching the middle of the list's
viewport: the list starts to scroll-down.
6) Then, toward the end of the list: scrolling stops and the selection
keeps moving down until the last item is reached. It's a common
feature in (keyboard-enabled) UI frameworks but I don't believe it's
possible to achieve with Android, as for now


After fishing for answers on the internet and the android source.
Looks like Its not supported, but I did notice there are a few private
functions in ListView, (e.g. function fillFromMiddle(int, int),
fillFromSelection(int, int)) what do these do?

I also see 'mLayoutMode = mStackFromBottom ? LAYOUT_FORCE_BOTTOM :
LAYOUT_FORCE_TOP;' on data changed function which always forces my
selected Item in the list view to be on the top. Is there a way to
change that?


(FYI: setSelection on the listView to switch between items was too
slow for fast scrolling through a big list so I had to resort to using
scrollBy functions)

To work around this problem. I tried to dispatch touchevents and
achieve scrolling functions like (smoothScrollBy(..) ). As my device
isn't a touch based device I DO NOT get a onSCrollStateChanged, even
though I do register onScrollListener. is there a way to work around
this? (Is there a way to fake the device to think its a touch based
device even if its not, the device I am working on is a custom device
so I can modify the platform code as well, please let me know if this
is possible)

Also, Is there a way to enable fast scrolling programatically?

[android-developers] Can't attach my devices anymore...

[Amokrane Chentir]

Hi,

I have an issue here with the ADB tool. Since this morning I cannot
attach my devices anymore like I used to do for the last two months or
so. Nothing has changed in my configuration, I am still running the
very same version of Ubuntu 10.10 that I was running before.

Also, this is the content of my rules file (in /etc/udev/rules.d/51-
android.rules) :

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8" MODE="0666", GROUP="plugdev"
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1" MODE="0666", GROUP="plugdev"

(since I have both Samsung Spica and Nexus S devices).

I gave the file a et r permissions (chmod a+r) and restarted udev.

On the device side, unknown sources is enabled and same for debug
mode.

Can't find what is wrong!

Thank you for your help!

[android-developers] SEGFAULT in toolbox mount

[Jeremy C. Andrus]

I have found a bug in the toolbox utility.
Not having participated in this forum before I wasn't sure exactly
where to send this. I have attached a patch which fixes the buffer
overrun issue in mount.c (which caused a segfault for me). The problem
is that 'len' is incremented _after_ 'newlen' is calculated. If you
have two arguments where the second is exactly 2 characters longer
than the first, then the writing of the NULL character by strcpy()
will overrun the allocated buffer when copying the second argument
(because no space was allocated for the ',' character).

Hopefully that made reasonable sense. If not, the diff should show the problem.

I receive digest emails, so please email me directly with any problems
- thanks :-)

-Jeremy

[android-developers] Live Folder and Application Logout

[Zhenia Krivopaltsev]

The application I develop has a live folder. I wonder how to close the 
folder programmatically when a user logs out, it has a sensitive data which 
should not be exposed in such case.

Re: [android-developers] Re: CountDownTimer too slow ???

[Sebastian Tomaszewski]

Hello all,
Nikolay, thank you for posting this problem that you are seeing. I get the
same problem when I use this timer in my code and I have no idea what could
be the issue...  If anyone know the reason why or how to improve it, I would
greatly appreciate the answer as well.
The followinig are some questions that come into my mind:
1. Is there some more occurate timer out there?
2. Could this potentially be because there are many other applications
runnign in the background?
3. Is there someway to turn off those applications?
NOTE: I posted questions 2 and 3 in my earlier post and didn't get a
responses...

Thank you again for all of your help and I greatly appreciate your response.

[android-developers] Inflated Window has unwanted background

[Skyre]

In one spot of my app, I use a LayoutInflater to create a little
settings window.  On versions of Android prior to Gingerbread this
works beautifully, but on Gingerbread there is an unsightly black
background shown behind the XML view.  It seems to be like a base
context menu background or something, but I cannot for the life of me
figure out how to get rid of it, as it really makes things look bad.

I figured if I set the window to wrap_content that it would just
shrink down to the size of the XML and be fine, but it is still
slightly bigger on the Y, and stretches all the way across the screen
on the X.  Even if I set the size to exact pixel values, or ones based
on the pixel width/height of the screen, you can still see the black
background, and if I do that it also does this weird graphical glitch
on the side that makes it look even worse.

If somebody knows of a simple solution to this I'd be really grateful
to hear it.  Ideally I'd like to fix it without ruining the current
setup, since it works perfect with older versions, but I'll do
whatever has to be done to get it done right.

Thank you.

Is IPv6 fully support in Android OS 2.3.4 or not?
Currently, when connecting to WIFI, I only get IPv4 address. I am sure
the Wifi hot spot support IPv6 because my laptop can get IPv6 address

If it support, does anyone know how to get the IPv6 address?

[android-developers] Android Battery Reporting Error

[Musicexplorer]

Hi,

we got a lot of reports from our users that our Android app consumes a
lot of battery. After some extended debugging sessions I now suspect
that the battery reporting of Android (concerning sensors) might be
incorrect. It seems that no matter how you unregister the sensors that
you have used, they are still being looked at as active by the battery
reporting tool. To reproduce the error:

1. Compile the official Android sensor example (Accelerometer Play)
from 
http://developer.android.com/resources/samples/AccelerometerPlay/src/com/example/android/accelerometerplay/index.html
2. Upload it to the phone and start it
3. terminate it with the back button (after approx. 5 seconds)
4. disconnect the usb cable
5. wait some time (e.g. 20 seconds)
6. open the dailpad and enter *#*#4636#*#*
7. click on battery history=> other usage => Sensor usage =>
Accelerometer Play
8. The displayed sensor usage time is larger than the time the
activity was in foreground
9. If you repeat step 7 you will see that the sensor usage value still
increases, even tough the app is not running anymore

I reproduced this error on a Motorola Defy with Android 2.3.4 and a
Nexus One with Android 2.3.4. The error does not occur on a HTC Desire
running Android 2.2. Alternatively you can observe the same thing by
using adb (instead of the tool from the dialpad): adb shell dumpsys
batteryinfo

I would appreciate it if someone would help me to find a way to
correctly unregister the sensors (on 2.3.4 devices).

Regards,

Samuel

[android-developers] Android native messaging framework (Looper, Handler, MessageQueue, Closures, ...)

[Daniel]

I have started to implement some of the Android messaging classes that
are normally only available within the Java framework for native code
development in C++. I have done that because we do a lot of native
code development for our hardware platform to implement additional
features and therefor we also do a lot of multithreaded programming. I
like Android's messaging framework very much, so I don't want to
reinvent the wheel all the time for native concurrent programs :-).
The framework also works with your desktop Linux system or with QNX
Neutrino RTOS.

You can find the source code with a small test program here (Apache 2
license): 
https://code.google.com/p/himmele/source/browse/#svn%2Ftrunk%2FAndroid%20Messaging

The following is currently NOT implemented but I will do this in the
future:
- use Android's reference counting mechanism (smart pointers) based on
RefBase, sp<...> and wp<...>.
- add the Binder IPC interface by implementing the Messenger class as
the Java framework does.
- add Bundles and Parcels.
- implement a native AsyncTask class (including Java's
ThreadPoolExecutor)

If you would like to submit some of the planned features feel free to
do so.

Br,
Daniel

[android-developers] Byte array to ImageView

[Denis Gottardello]

Hello everybody. I'm trying to show a jpeg image stored in a byte
array on a ImageView object.
I'm sure that the byte array contains a jpeg image correctly because,
if I save it in a file, with another editor I can see it correctly.
For show the image I'm trying in this mode:


android.graphics.Bitmap a=
android.graphics.BitmapFactory.decodeByteArray(Data, 0, Data.length);

a.recycle();

android.widget.ImageView IVCamera=
(android.widget.ImageView)Live.findViewById(R.id.IVCamera);

IVCamera.setImageBitmap(a);

but does not work.
Do you know wich is the right way?

Re: [android-developers] WRITE_EXTERNAL_STORAGE (not set, but i write to sdcard)??

[Feign Narula]

Hi,

This only works on Android v 2.2 and above and below this version all
application data would be stored on the internal storage.

Try using this permission below Android 2 and you will find the
difference, you cannot use this permission in manifest.

[android-developers] How can I know removed non-public API in Gingerbread

[burnbrain]

Dear All developers,

Hello, I have some problem to use
com.android.server.status.AnimatedImageView on Gingerbread.
It works fine until 2.2, but it doesn't run on 2.3.
I have found the cause that the AnimatedImageView doesn't exist in
2.3.

If so, what API can I use to indicate downloading instead of
AnimatedImageView?
And, How can I know removed non-public API in 2.3, 2.4 or 2.5 and so
on (on the future version)?
Shouldn't I use non-public API?

Please advice~
Thank you.

[android-developers] cvLoadImage cannot be executed on emulator

[Leo_China]

hi all,
i want to develop a program with openCV,all steps for development is
done and .so lib is generated normally.
but when i run as this program in my emulator,it will exit after about
1s and the UI is not correct.My code snippet  lists below:

IplImage* imgIn = cvLoadImage("/sdcard/testimage.bmp");

if (!imgIn) return env->NewStringUTF("Error");

std::string filePath="/sdcard/result.bmp";
 jstring filePath1=env->NewStringUTF(filePath.c_str());
const char * resultpath=env->GetStringUTFChars(filePath1, 0);
cvSaveImage(resultpath,imgIn);

cvReleaseImage( &imgIn );

return env->NewStringUTF("ok");

when i eliminate the code about openCV,the program run normally.when i
add only cvLoadImage,the problem comes again.I get a blog about this
problem,it says that openCV will be run arm V7 in priority,but the
emulator based on arm V5,so need edit the android-opencv.mk.but this
blog is about openCV on Linux,i develop program in winXP+cygwin and i
cannot find the related .mk files.

i didn't test my program in a real device,someone said that the
program maybe can run normally in a real device if run abnormally in
emulator,sadly i don't have a real device in hand.

so is there anyone can tell me how can solve this problem?

[android-developers] Battery Low (Below 15%) limitations in usage

[Larama Amaral]

Good Afternoon all

I'm a new user of android, previous user of iphones... for now a good
experience, that as to be improved a lot (apple is light years ahead
in many subjects regarding android), but one of the most stupid things
that i've seen on the android phone is the limitation of usage of (for
example the camera, youtube and other applications when you are 15% in
batery or less)

I think that this limitation should be optional, that you could turn
on or of, i use my phone as i like and if i want to drain my battery
leaving the camera on, is my option
Yesterday i really need to take a quick picture when i was working and
i couldn't because of this nonsense limitation.

A really great shoot in the foot by google...

[android-developers] Distinguish Declined call from Missed call

[Petr Šimek]

I need to watch if the phone user declined an incoming call.
I am using my own subclass od PhoneStateListener where in onCallStateChanged 
method I am testing the state on values of 
TelephonyManager.CALL_STATE_IDLE, CALL_STATE_OFFHOOK and CALL_STATE_RINGING.
Everything is working as I assumed except for one thing:

When the phone user declined an incoming call *behaves exactly the same* as 
missed call (ie. call is terminated by caller).

Is there any chance to distinguish these two types of terminated call?

[android-developers] Is there a special reason why hasVibrator wasn't introduced prior API level 11?

[mainerror]

Today I've documenting the Vibrator classes hasVibrator method on
Stack Overflow[1] and all was fine until someone mentioned that the
method was added with API 11[2]. I didn't notice since my API level
filter is set to 12.

I think it is quite a good question.

Were there no device without a vibrator prior Honeycomb? Is there a
special reason for the addition of that method?

[android-developers] Why up-scaling a smaller image into an ImageView does not work?

[tiba]

Hey all,

does anybody have a clue what I do wrong?

There's an image "guy.png" size 50x50 pixels and I'd like to get this
up-scaled.
Just for reasons of testing I tried to get it fitted with aspect ratio
maintained into an ImageView of 200dip(!) height like this:




But that just won't work. The image does not grow larger. The maximum
size is the original image size.

Does somebody know why?

Thanks in advance,
till

[android-developers] Most Efficient (TIMING) way to save the images onto the Tablet!!!!

[Sebo]

Hello All,

Here is my Problem, I am trying to safe an image (1280x800) into the
memory and I am running into some timing issues Meaning I want to
get it done As fast as possible wihtout losing the image sizing and
crispness I had been trying to resolve this problem for last
couple of days and I am running always to gotchias (The final
destination of the Image I want it to be in the SDCARD)

1.  I tried writing directly an image to the SD-CARD and it took about
about 180 msec
2. I tried writing to internal cache memory first (160msec) and then
copying using the FileChannel the image to SDCARD (4msec)

Does anyone know what would be even faster?
If there is no faster way to do this, that is fine, but I just want to
make sure that I visited all of the possible ways.

Thank you all for your help ahead of time.

Thank you and Best Regards,


Sebo

[android-developers] Issue with Android Menu

[mwllace]

I'm new to Android and I'm a front end designer. Im trying to get the
Android menu buttons to open a new activity using a case statement to
specify the activity. The activity works when I set it to any other
button in the App. The menu shows up when the hard menu button is
pressed, but they will not link to the specified Activity. I'm stuck
and I know I'm overlooking something simple. Can anyone help?

The code:



@Override
 public boolean onCreateOptionsMenu(Menu menu) {

menu.setQwertyMode(true);
menu.add(0,MENU1, 0, 
R.string.about).setIcon(R.drawable.icon);
;
menu.add(0, MENU2, 0, 
R.string.usage).setIcon(R.drawable.icon);
;
return true;
}


 public boolean OnOptionsItemSelected(MenuItem item){
 switch (item.getItemId()) {
 case MENU1:

 Toast.makeText(getApplicationContext(),
"About  was clicked.",
 Toast.LENGTH_SHORT).show();

 Intent intent = new Intent(XActivity.this, 
AboutActivity.class);
 startActivity(intent);


 return true;
 case MENU2:
 finish();
 return true;


 }
 return false;
 }

[android-developers] Turning off all of the APPS running in the background or setting the highest priority on my APP!!!

[Sebo]

Hello All,
Quick question, do you know if there is a way to turn off any APPS
that run in the background (e-mail/GPS...), so my application while it
is running won't be interrupted at all(Except for the OS of
course)?.   BOTTOM line the following is what I would like to do:
1. As soon as my APP Enters, it would turn off the other background
APPS/Services/Tasks (Except for OS) from running.
2. Perform operations without being interrupted
3. On the exit, the APP would re-enable all of those apps to run?

OR is there a way to tell when my application starts that my APP is
the highest prioiryt in the whole system?  I tried setting my
Acitivity prioity (In the Manifest) to the highest possible and that
didn't work that well.

Please let me know if you have any suggestions..

I greatly appreciate it.

[android-developers] Emulator bigger than my screen

[paulkinzelman]

I'm just starting learning the Android development environment, managed to 
get Hello World going...

However, the emulator window on my Vista display is larger than the display, 
some of it extends off the bottom of the screen. The tutorial doesn't say 
anything about how to fix that, and it looks like I can't drag the corner of 
the emulator screen to change the size. Is there a way to make the emulator 
window smaller? I realize that might affect the app interaction with the 
screen, but it seems there should be a way to fix this.

Also, I ran across a major stumblingblock on the tutorial page:
http://developer.android.com/resources/tutorials/hello-world.html
in that if you install the sdk in the default (under c:\program files) the 
emulator won't run because of the space. Fortunately a quick search turned 
up others that had the same problem. Seems the tutorial should warn about 
this, is there some way to report this to somebody to fix the tutorial? 
Other than a couple of items, though, the tutorial so far has been 
spectacular, thanks!

[android-developers] Handling of application icons in Honeycomb Launcher homescreen

[Laurent Sebag]

Hi,

I have a question regarding drawable resources on Honeycomb. I work on
a Motorola Xoom and I develop an application in which I want to show
the installed applications icons in the same size as the Launcher app
does (72x72px).

As far as I understand the Motorola has a 10" 160dpi screen making it
mdpi and xlarge.
So when I use the PackageManager to fetch the Bitmaps, they come in
48x48px instead of 72x72px which seems normal since the PackageManager
returns me the drawables contained in the res/drawable-mdpi of each
apps.

The Launcher homescreen application on Honeycomb seems to be able to
fetch the hdpi icons of apps to display them. What mechanism does it
use? Can I do the same on my app?

Kind Regards
Laurent

[android-developers] Button add programmatically not clickable

[deveLoper]

Hi,
I need to add some of my buttons programmatically since the titles are
coming from a database that may change. The buttons are being add
fine, but are not clickable. I am using a custom background for the
buttons, but I am using the same background for some button I am using
from xml and they work find. If I add the line
countybutton[i].setFocusableInTouchMode(true); , the button can focus,
but doesn't click. I also tried to set it clickable, but it didn't
work. Here is my code:

res = getResources();

button_background = res.getDrawable(R.drawable.custom_button_gray);
context = getApplicationContext();
float scale = context.getResources().getDisplayMetrics().density;



for(int i = 0; i < county.size(); i++){
countybutton[i] = new Button(this);
countybutton[i].setText(county.elementAt(i));
countybutton[i].setBackgroundDrawable(button_background);
countybutton[i].setLayoutParams(new 
LinearLayout.LayoutParams((int)
(85*scale),
LinearLayout.LayoutParams.FILL_PARENT));
countybutton[i].setTextColor(Color.WHITE);
countybutton[i].setTextSize(13 * scale);
countybutton[i].setOnClickListener(listener);
county_linear.addView(countybutton[i]);

}

listener = new OnClickListener(){

@Override
public void onClick(View v) {
Log.d(TAG, "a button was clicked");
}

};


any suggestions?

[android-developers] Android SDK Manager Failed to fetch URL

[Alexandra Kulik]

Sometimes in the Android SDK Manager appear problems with updating the
installed package or with installing new packages and you can get
error: "Failed to fetch URL 
http://www.echobykyocera.com/download/echo_repository.xml/addon.xml,
reason: Server returned HTTP response code: 403 for URL:
http://www.echobykyocera.com/download/echo_repository.xml/addon.xml";

There are the several methods that maybe can help you:

1. Start SDK Manager with administrator privileges
(In Windows right click on "SDK Manager.exe" and select "Run as
Administrator").

2. Maybe you need select HTTP instead of HTTPS
(Go to "Settings" and select "Force https:// ... sources to be
fetchign using http:// ...").

3. If you have proxy-server you must specify it
(Go to "Settings" and insert your HTTP Proxy Server and HTTP Proxy
Port in appropriate cell).

4. Disable all antiviruses and firewalls or add Manager to the list of
exception.

[android-developers] My service never runs more than few ours while other services run for days

[scmailon]

Hi there!

I am trying to do a (remote) service that holds a TCP connection open
to receive notifications (after the activity is closed), but it seems
that Android restarts the service every few hours. It could be 1 or it
could be 3, but it never runs for much longer.

Looking at my device I can easily see 7 services that have been
running for more than 78 hours!!!

Could this be related to a memory leak on my service?
   - Note: I have never seen it holding more than 10 MB

Could it be related to a crash?
   - Logs do not show any exception, but I might be missing some...,
is there any way of making sure I do not miss any exception?

Any idea suggestion is very wellcome :)

[android-developers] button id causes app to crash

[DB12]

Howdy, I searched for about 30 minutes to see if anyone had the same
issue but couldn't find anything.

I have a custom dialog I created with a relative layout, when the user
clicks on a button it brings up the dialog just fine normally.  I
added a few buttons to the dialog layout and this is where the trouble
begins. For some reason when I add an id to the third button, my I get
a runtime exception/force close dialog when my app starts up.  If the
third button has no id, the app works fine.  The other two buttons
already have id's and work great.
so in summary...

this layout works fine

http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">






and this one gives me a force close runtime exception when my app
starts

http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
