[android-developers] Android 10/11 : surfaceFlinger / RenderEngine evolutions: need help

[Vincent Arvis]

Hello
I want to port an image enhancement after the composition is done by 
Surface Flinger, and before the final HWC rendering.
Up to Android 10, the renderEngine class provided fluch() and close() 
functions.
So we called our full screen image enhancement , then we asked the 
renderEngine to finalize thanks to flush and close.
These functions have disappeared from Android 11 because deprecated.

Version used 
: 
https://cs.android.com/android/platform/superproject/+/android-11.0.0_r4:frameworks/native/services/surfaceflinger/

What I don't understand is how can I read what the RenderEngine does (even 
in RenderEngine.h/cpp)

Thanks a lot to share some ideas ??
Best
Vincent

[android-developers] Re: Periodic Sync not working.

[Vincent Wassenaar]

Well after trying to figure out the same problem I found a few things.
First of all the time is in seconds so now you sync every 3600 seconds. Try 
30 or so.

Secondly make sure the AUTHORITY is equal to the one provided in the 
authenticator.xml AND the syncadapter.xml

Hope this works for you :)

[android-developers] app hanging

[android-developers] Issue with ContentProvider streaming data to other apps

[Vincent]

Hello,

In my app the user can select files and open them in the appropriate app (using 
an ACTION_VIEW intent). I need to do some work on the data before giving it to 
the other app. So I'm using a streaming solution : I've implemented a 
ContentProvider that implements openTypedAssetFile and writeDataToPipe (this 
method fills the output ParcelFileDescriptor created by openPipeHelper).

This works : I can open .pdf files, .txt files etc. The streaming seems 
correct. I can open images usings 3-party apps. However when I open an image 
using the Gallery, it doesn't work (Gallery shows a black screen), and I get 
the following exception :

fail to open myfile.jpg
UriImage(21890): java.io.FileNotFoundException: Not a whole file
I had a look at the Gallery source (here) and I could see that the exception is 
thrown here :

try {
if (MIME_TYPE_JPEG.equalsIgnoreCase(mContentType)) {
InputStream is = mApplication.getContentResolver()
.openInputStream(mUri);
mRotation = Exif.getOrientation(is);
Utils.closeSilently(is);
}
**mFileDescriptor = mApplication.getContentResolver()
.openFileDescriptor(mUri, r);**
if (jc.isCancelled()) return STATE_INIT;
return STATE_DOWNLOADED;
} catch (FileNotFoundException e) {
Log.w(TAG, fail to open:  + mUri, e);
return STATE_ERROR;
}
However, once in the Gallery app, if I select Set as wallpaper, then I can 
see my image, it is then well streamed. So the problem appears when Gallery 
opens.

After a deeper look (in the ContentResolver code etc.) I couldn't understand 
why it behaves this way. It seems that Gallery does not support streaming 
files. Is that right ? Do you have any idea ? I really lost with that right now.

Thanks

Vincent

[android-developers] Re: how to display a toast after 10 seconds from starting Asynctask

[Vincent Senese]

I think you can do this.

(CountDownTimer) cdt = new CountDownTimer(0, 1000) {

 public void onTick(long millisUntilFinished) {
   //  mTextField.setText(seconds remaining:  + millisUntilFinished / 
1000);
 }

 public void onFinish() {
 //mTextField.setText(done!);
 }
  }.start();

// at the end of your thread call 
cdt.stop(); //

[android-developers] Connection over data network

[Vincent]

Hi,

I'm having some problems connecting to the data network (3G
connection). I added the internet permission and can access it when
using a WIFI connection. When using the data connection of the phone
network it somehow seems that I can access the URL's I'm calling. Any
ideas, do I need to add other permissions to the manifest ?

For your information, I'm using the DefaultHttpClient in combination
with an HttpPost to access my server (JSON request).

Any help/suggestion is welcome.

Greetings,

Vincent

[android-developers] How to assign color resources to preferences in Preference Activity?

[Vincent]

Hi,

I want to store some preferences related to colors and these preferences 
will be used by some activities.

What I need are background color and foreground color preferences, in the 
preferences.xml file:

PreferenceScreen
PreferenceCategory

Preference
android:key=foreground_color
?how ot set value here? /

Preference
android:key=background_color
?how ot set value here? /

/PreferenceCategory
/PreferenceScreen



And in the preference activity, I want to change these preferences (I know 
how to get input from users, so just list the code for changing 
preferences):

addPreferencesFromResource(R.xml.preferences);

// get preferences and editor
preferences = PreferenceManager.getDefaultSharedPreferences(this);
editor = preferences.edit();

Preference mBackcolor = (Preference) 
findPreference(background_color);
Preference mForecolor = (Preference) 
findPreference(foreground_color);
editor.// ?? how to set color here?


Finally, I need get these color preferences in activities, it would be 
something like:

SharedPreferences preferences = 
PreferenceManager.getDefaultSharedPreferences(this);
int COLOR_BACKGROUND = preferences.get// ? how to get color from 
SharedPreferences?
int COLOR_FOREGROUND = preferences.get// ?



I'm new to Preference Activity, I can now use it to change Strings.
I want to know if it is possible to change color preferences, and if yes, 
how?

[android-developers] How to make Sliding Drawer push a existing layout when showing?

[Vincent]

Hi,

I have a relative layout and a sliding drawer in a frame layout, it works 
fine, I can pull out the drawer and it shows on the top of the relative 
layout.

However, now I want to make the sliding drawer push the relative layout 
when showing.

I've searched on google and the android dev ref, only got a not well

Re: [android-developers] How to make Sliding Drawer push a existing layout when showing?

[Vincent]

Apologise for ambiguous question.

You said there's no way do to that with SlidingDrawer, I am wondering if 
I can get the animation with other widget/layout/view.

What I want are: 
   when I slide a numpad from the right side, the current match_parent 
layout becomes smaller. 
   when I push the numpad back, the layout becomes match_parent again.

Re: [android-developers] How to make Sliding Drawer push a existing layout when showing?

[Vincent]

I figured out how to use OnDrawerOpenListener and OnDrawerCloseListener to 
implement the animation.
 
   SlidingDrawer drawer = (SlidingDrawer) 
findViewById(R.id.slidingDrawer1);
drawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {
public void onDrawerOpened() {
ImageView image = (ImageView) findViewById(R.id.imageView1);
LinearLayout.LayoutParams layoutParams = new 
LinearLayout.LayoutParams(500, 500);
image.setLayoutParams(layoutParams);
}
});

drawer.setOnDrawerCloseListener(new OnDrawerCloseListener() {
public void onDrawerClosed() {
ImageView image = (ImageView) findViewById(R.id.imageView1);
LinearLayout.LayoutParams layoutParams = new 
LinearLayout.LayoutParams(700, 700);
image.setLayoutParams(layoutParams);
}
});


However, I want the image changes its size in a gradient way, and its size 
depends on the position of the drawer's handler button.

Re: [android-developers] How to make Sliding Drawer push a existing layout when showing?

[Vincent]

Another thing is how to change a button's attributes at run time.

say, for example, I have four buttons in a relative layout (as the code 
showed in my first post).
After the slidingdrawer opened, I am able to change the relative layout in 
this way:

SlidingDrawer drawer = (SlidingDrawer) 
findViewById(R.id.slidingDrawer_landscape);
drawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {
public void onDrawerOpened() {
RelativeLayout layout = (RelativeLayout) 
findViewById(R.id.screen_landscape);
layout.setLayoutParams(new FrameLayout.LayoutParams
 (900, LayoutParams.MATCH_PARENT));
}
}

But how can I change the attributes of the buttons (width, height and 
margins)?

Re: [android-developers] Can Android do waitForResponse?

[Vincent]

Thanks a lot for your reply.

I am also thinking about doing this in a asynchronous way.

However, I'm quite new to Android (about two weeks) and the only Bluetooth 
sample I've seen is the official BluetoothChat application.
So if possible could you give me a little bit more detailed guide (directly 
or links)?

I want to send a command to a device, then receive data from it, then send 
another command... 
but the only way I can think is the BluetoothChat way :(

Re: [android-developers] Can Android do waitForResponse?

[Vincent]

Thank you. 

I created a global variable int N and a boolean FLAG 

and use a method to initiate

void function() {
N = 0;
FLAG_COMMAND = true;
mService.write(command((byte) N));
}



private final Handler mHandler = new Handler()
 {
 @Override
 public void handleMessage(Message msg) { 
 switch (msg.what) { 
case MESSAGE_READ:
byte[]readBuf = (byte[]) msg.obj;

Packet rPacket = new Packet(readBuf);

if (FLAG_COMMAND  N = 10) {
if (rPacket.isValid()) {
doSomething(rPacket);
N++;
} else {
N--;
}
mService.write(command((byte) N));
} else if (N = 10) {
FLAG_COMMAND = false;
N = 0;
}
break;
  }
 }
}


Now it works, but the code is dirty and inefficient, I want to know how to 
do it in a *normal* way, but not Trying to shoehorn the synchronous model 
into the asynchronous model.

Re: [android-developers] Can Android do waitForResponse?

[Vincent]

Yes, you are right, it is not inefficient, my fault. 

The activity has a button, after clicked, it will *call* function(). 

However, the code I posted last time is wrong (see the N-- part), I've 
changed the code a little bit:


case MESSAGE_READ:
byte[]readBuf = (byte[]) msg.obj;


Packet rPacket = new Packet(readBuf);

if (FLAG_COMMAND   N = 10) {
if (rPacket.isValid()) {
dosomething(rPacket);
N++;
} 
mSerinusService.write(command((byte) N));
} else if (FLAG_COMMAND  N = 10) {
FLAG_COMMAND = false;
N = 0;
}
break;

When the activity receives some data, it will check if FLAG_COMMAND is true 
and if N is less than 10 (which means the task hasn't been done).
  If yes, then check if the data received is valid
 if yes, do something with the data, and N++, then write a command(N) 
to the outputStream.

 if no, write command(N) (N hasn't been changed in this case) to the 
outputStream again.

And if N has reached 10, set FLAG_COMMAND to false and reset N.



But it doesn't work...I think there is some logic mistake in my code.

Re: [android-developers] Can Android do waitForResponse?

[Vincent]

figured it out, a small mistake in the isValid() method.

I learned how you write asynchronous code from you, thanks a lot. And 
please forgive my foolishness :)

[android-developers] Problem with handler

[Vincent]

Hi,

I am currently developing a project which needs to write/read data via
bluetooth.
I met a werid problem when I try to use a handler to deal with the
information back from the service I created.



When I put a breakpoint after  bytes = mmInStream.read(buffer);
 ( in ConnectedThread.run() )
I can see the content in the buffer is:

[2, 0, 8, 3, -15, 16, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 99, 12, 30, 99, 0, 99, 127,
99, 51, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
119, 30, 12, 103, 0, 119, 70, 103, 51, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 127, 51, 12, 111, 0, 127, 22, 111,
51, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
107, 51, 12, 123, 0, 107, 30, 123, 51, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 99, 63, 12, 115, 0, 99, 22, 115, 51,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 99, 51,
12, 99, 0, 99, 70, 99, 51, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 99, 51, 30, 99, 0, 99, 127, 99, 63, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, -23, 4, many
0s...]

and the bytes = 248.
These are what I expected.

However, in the hanlder, the content of readBuf becomes:
[99, 51, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 99, 51, 30, 99, 0, 99, 127, 99, 63, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, -23, 4, 0, 0, 0, 0, 0, 0, 107, 51,
12, 123, 0, 107, 30, 123, 51, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 99, 63, 12, 115, 0, 99, 22, 115, 51, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 99, 51, 12, 99,
0, 99, 70, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, ...many 0s...]



The werid thing is, if the bytes = mmInStream.read(buffer); reads
[2, 0, 8, 3, 31, 32, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 55, 4, ...many 0s...],
(bytes = 38 in this case)
then the handler can get the correct content.


I cannot figure out why, I think it is a handler mistake, any hint?

[android-developers] Can Android do waitForResponse?

[Vincent]

Hi,

I am developing an application to communicate with a device via bluetooth.
Same as the BluetoothChat sample, my application makes a service object, 
and call service.connect() to get a connectedThread for data transmission.

and I have a command method, which takes an integer as its parameter.

the problem is, sometimes, that device returns invalid data.
So when I want to execute the command with ten different parameter, I need 
to do something like :

for (i = 0; i  10; i++) {
myService.write(command(i));  
packet = *waitForResponse*(myService);

if (packet is valid) {
do something;
} else {
i--;
}   
}


My program is using handler to deal messages, e.g. when the connectedThread 
read some data, it will 

mHandler.obtainMessage(ControlActivity.MESSAGE_READ, -1, -1, data)
 .sendToTarget(); 

And there is a handler in my Activity class to deal with these messages.

How can I do something like *waitForResponse* on Android? 
or Is there any other way to meet my requirement?

[android-developers] How to create a bitmap from binary data?

[Vincent]

Hi,

I want to create images from binary data.

e.g.
If the binary data is：

0110 1110 0011 1010
1000 0001 1011  1100
0110 1101   
0100 0011 1001 0011


which is store in 4*4 bytes
{
6 14  3  10
8  1  11 12
6 13 15  0
4  3   9   3
}

I want to create a image(might be bitmap) from the binary data,

if 1, draw a black pixel, if 0, draw a white pixel
so the image would be
 .. ...   ... .
.  .. 
 .. .. .
 ....  .  ..

And I will receive new data and refresh the image frequently.

Could you give me some hints/suggestions?

[android-developers] Layout problem related to RelativeView and ListView

[Vincent]

Hi,

I'm trying to make a layout that contains a List and a button.
To make the button on the bottom, I'm using

 android:layout_alignParentBottom=true
 android:gravity=center|bottom

in a RelativeView


It works fine when the list is short, however, once the length of the
list beyond the screen's length, the list will be hided by the button
(as the link pic shows).


What I want are:
1. Keep the button on bottom
2. Keep the list above the button
3. Use relative position to keep the program's flexibility

Could you give some suggestions?

[android-developers] Intent filter to catch links from SMS doesn't work

[Vincent]

Hi all,

I actually already asked this question on StackOverflow but I didn't
get any answer that could help me solve the problem.
Here is the thing.

What I want to do is to define a URI like myapp://some_data in a
intent filter. And when this kind of URI is met in a SMS or email,
clicking on it would open myapp.
I found on StackOverflow the way to do it. Here is my code:

intent-filter
action android:name=android.intent.action.VIEW/action
category android:name=android.intent.category.DEFAULT/
category
category android:name=android.intent.category.BROWSABLE/
category
data android:scheme=myapp/data
/intent-filter

However it does not work. Actually, if I have such a link in a SMS, it
is not clickable...so of course clicking on it does nothing.
If instead of android:scheme=myapp I am using android:scheme=http
it does work. When I click on the link, Android asks the user whether
to open it with Browser or myapp and it simply works because the link
is clickable (http web adress is always clickable).

What should I do to make my link myapp://some_data clickable in a SMS/
email ? As the intent filter works with http, I guess it can work with
myapp as a scheme.

Thanks a lot.

  screen orientation.

  Parameters params = mCamera.getParameters();
  params.set(orientation, portrait);

  It worked for the most of devices.
  However, after updating my NexusOne to2.2, the above code does not
  work!!
  Is there any other way to change the orientation?

  The only way to change the orientation is to change the orientation of
  an Activity.
  setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
  But, I don't want to do this because I have other controls like Text
  or Button on Screen.

  If somebody knows the solution for this, please help me!!

[android-developers] Is It possible to have memory leaks when android apps exit.

[Vincent]

Hi,

I have a question about memory leaks.
My tester told me a condition.
He runs my app 100 times, and monitor the memory capacity.
Then he says my app has memory leaks.

My question:
Is it possible to have memroy leaks when app alread terminated.

OS memory management of Android should release the memory of
terminated process normally.

Thanks in advance.

Re: [android-developers] [Help] how to place item in GridView

[Vincent Tsao]

Hi, Mark, thanks a lot.

Using RelativeLayout, or nested LinearLayouts, i need hardcode for the
display and event for each item, which i really hated, GridView provides me
smooth APIs to meet my needs, BTW, if i have 3*N items someday, my problem
is not exist any more.

so, i find this tricky way, one general speaking, use holder item to fill in
GridView, then make those holder items invisiable:

[image: 3.png]


Finnaly, that's working!

Sigh~~, a weird requirement and a really tricky solution :)

 Don't use a GridView. Use RelativeLayout, or nested LinearLayouts.

[android-developers] MapView crushes in satellite mode if android:anydensity is set true

[Vincent]

Hi,

On Android 1.6 WVGA device, a map view in satellite mode crushes when
the map zoom-in too much if I specify android:anyDensity=true in the
manifest file.
But, if I set android:anyDensity=false, then the map does not crush.

I want my app to support a multiple densities and also do not want to
make the map crush.
Is there any way to do this?

I tried to control zoom level of the map, but getMaxZoomLevel() method
in satellite mode does not return a correct value.
Please help me out!!

[android-developers] [Help] how to draw multiple lines in Edittext?

[Vincent Tsao]

i have a customized LinkedEditText extends from EditText, and override the
onDraw method as below:

protected void onDraw(Canvas canvas) {
canvas.drawColor(paperColor);

int count = getLineCount();
int height = this.getMeasuredHeight();
int line_height = this.getLineHeight();
int page_size = height / line_height + 1;

if (count  page_size) {
count = page_size;
}

for (int i = 1; i  count; i++) {
int posY = i * line_height;

canvas.drawLine(0, posY, getRight(), posY, linePaint);
canvas.save();

}

  super.onDraw(canvas);
  canvas.restore();
}

here is what this customized EdtiText looks like:

[image: new_note_1.png]


as you can see, the text line-height didn't match the lines which i draw.

but AK notes App did it perfect:

[image: ak_note_1.png]

Re: [android-developers] Re: [Help] how to draw multiple lines in Edittext?

[Vincent Tsao]

It remind me of considering some margin space, so i change my code as below:

protected void onDraw(Canvas canvas) {
canvas.drawColor(paperColor);

int count = getLineCount();
int height = this.getMeasuredHeight();
int line_height = this.getLineHeight();
int page_size = height / line_height + 1;

if (count  page_size) {
count = page_size;
}

   * int posY = 5; // i guess the margin-top may be 5 px :)*
for (int i = 1; i  count; i++) {
*posY +=  line_height;*

canvas.drawLine(0, posY, getRight(), posY, linePaint);
canvas.save();

}

  super.onDraw(canvas);
  canvas.restore();
}

finally it looks right, so i'm sure there is a margin space between my
EditText  and the default view , but i have no idea about how to get this
height? so i hard code it 5 px

any suggestion?

[android-developers] [Help] How to get thumbnail picture from HTC Hero?

i'm trying to fetch a  thumbnail with picture URI using these code below:

long id = ContentUris.parseId(selectedImageURI);
String[] projection = { MediaStore.Images.Thumbnails.DATA };
Cursor c =
Images.Thumbnails.queryMiniThumbnail(getContentResolver(),
id, Images.Thumbnails.MINI_KIND, projection);

unfortunately, it's always return me the null cursor. finally, i found HTC
hero never generate picture thumbnail under \sdcard\DCIM\.thumbnails,  but
only create a picture under this folder: \sdcard\DCIM\100MEDIA, which
means i can only get the full size picture. What's am i supposed to do?
create a thumbnail by myself?

As you know, i can use System.currentTimeMillis() to fetch current local
time, but how to convert local time to UTC time?

the code below, i can get the timezone, utc_bias also can be got

Time mSavedTime = new Time();
mSavedTime.set(System.currentTimeMillis());
TimeZone mMyTimeZone = TimeZone.getTimeZone(mSavedTime.timezone);
int utc_bias = mMyTimeZone.getOffset(local_time);

my problem is i can't determine how to use this utc_bias:  added or minus to
current local time  to get UTC time?

 Are you sure that currentTimeMillis() gives you local time? It's
 documented as the current system time in milliseconds since January
 1, 1970 00:00:00 UTC. From that description, I'd expect it to return
 a raw millisecond count; there's no timezone offset involved. If
 anything, it's going to be UTC, but in truth, it isn't inherently in
 *any* time zone.

 It all depends on what you're wanting to do with the timestamp. We
 probably need more information to guide you here.

hi String,  i have misunderstand this description return the local system
time in milliseconds in doc. and ask this stupid question, sorry for that.
thanks for your response

[android-developers] Camera Questions: 1) Raw Bayer data, 2) NDK camera access

[Hugo Vincent]

Hi,

I'm interested in making some photography apps, and have two questions
about the current camera support in the SDK and NDK.

First, is it possible to get raw Bayer data from the camera sensor
(before any kind of demosaicing, color space conversions, noise
reduction etc)? Specifically on the Nexus One, but ideally in a
portable way. How about raw RGB pixel data (again, before noise
reduction, JPEG compression and so on)?

Second, is it possible to access the camera from the NDK for high
performance signal processing (using NEON instructions etc)?

Thanks,
Hugo

 If you are using the same permission for both read and write in the
 provider tag. You could also use the permission attribute.

 For example,

 android:name=.provider.myProvider 
 android:permission=com.example.project.permission

[android-developers] Please share the info about the problem app is not visible on Android Market

[Vincent]

Hi, All.

The end of last year, there were discussions about the problem
regarding to the visibility of apps on Android Market.

App Not showing up on Verizon DROID Phones
http://groups.google.com/group/android-developers/browse_thread/thread/6324add11decee78/ad4c75a4cd595046?lnk=gstq=not+visible+on+Droid#ad4c75a4cd595046

Our app is not visible on market for some devices
http://groups.google.com/group/android-developers/browse_thread/thread/c4dbe8574ae12812/a6bd96106988be9e?lnk=gstq=Market+HTC#a6bd96106988be9e

HTC Hero, missing applications from Market after firmware update
http://groups.google.com/group/android-developers/browse_thread/thread/fd299f64638391e1


From my understanding, if the app is copy protected, it is not
visible on HTC Hero and Droid Eris.

Does someone get any updated news?
The other devices are OK?

Please share the information because my users reported me that they
cannot see my app from MyTouch.
I would like to clarify which devices are fine and which are not.

Thanks in advance...

[android-developers] Is it possible to change background color of Preference

Hi,

Does anybody know how to change the background color of Preference
(PreferenceCategory, EditTextPreference ...) ?

I wanna do like this:
PreferenceCategory android:title=title_test
android:background=@color/testColor
But this doesn't work...
I searched these by using google, but couldn't find any right
answer...

Also, I couldn't find any way to change other layouts. (e.g. text
color, size and style of preference title or summary)
Is there no way to customize the layout of Preferences?
It'll be great if somebody can help me out.

[android-developers] Re: Is it possible to change background color of Preference

[Vincent]

Bob, joebowbeer, skink

Thanks so much for your help!!
I successfully managed to change the layout of preference.

As joebowbeer wrote, I changed the top-level background image and
listview setting in my code like below.
 
getWindow().setBackgroundDrawableResource(R.drawable.my_background);
getListView().setBackgroundColor(Color.TRANSPARENT);
getListView().setCacheColorHint(Color.TRANSPARENT);

Then, I supplied the custom layout to the android:layout attribute in
xml in order to change other child preferences as Bob stated.
PreferenceScreen xmlns:android=http://schemas.android.com/apk/
res/android
PreferenceCategory android:title=test_title
android:layout=@xml/preference_category
EditTextPreference
android:key=edit_key
android:title=edit_title
android:summary=edit_summary
android:layout=@xml/preference
/
/PreferenceCategory
/PreferenceScreen


Thank you very much!!

 i'm afraid it works only for top-level preferences.

 if you have inner ScreenPreferences it won't work as ScreenPreferences
 use Dialogs in order to show their child Preferences

  Before Android 1.5, I can use ZoomControls which has a
  setOnZoomInClickListener().
  In order to get zoom controls, I can write like this:
      ZoomControls mZoom = (ZoomControls) mMapView.getZoomControls();

  But, since 1.5, the mMapView.getZoomControls() is deprecated.
  Instead of this, the documentation suggests using
  mMapView.setBuiltInZoomControls.

  Since 1.6, I can use ZoomButtonsController, which has a set
  OnZoomListener().
  In order to get zoom button controls, I can write like this:
     ZoomButtonsController mZoom = (ZoomButtonsController)
  mMapView.getZoomButtonsController().setOnZoomListener(this);

  So, how can I get map zoom in/out event without using
  mMapView.getZoomControls() for Android 1.5 ?

[android-developers] Set ringtone from raw resource?

[Bryan Vincent]

So I'm having a hard time setting a ringtone from a raw resource. My
code is below. Any help would be much appreciated.

RingtoneManager.setActualDefaultRingtoneUri(getApplicationContext(),
RingtoneManager.TYPE_NOTIFICATION, Uri.parse(android.resource://
net.thebosskey.gijoepsasoundboard/ + this.resource));

However, when I play back the default notification sound using the
line below, it is not my sound.
RingtoneManager.getRingtone(getApplicationContext(),
RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)).play
();

I know the uri for my sound is correct because the following line
plays it:
RingtoneManager.getRingtone(getApplicationContext(), Uri.parse
(android.resource://net.thebosskey.gijoepsasoundboard/ +
this.resource)).play();

What am I doing wrong?

 Hi guys,
 I'm trying to create a simple list for my app extending the
 ListActivity Class.
 All names the names I want to display are stored in an ArrayList, and
 I use ArrayAdapter to link each element of the array with a row in the
 list view. This is the code to instatiate the ArrayAdapter:

 ArrayList listItems = new ArrayListString();
 ArrayAdapter aa = new ArrayAdapterString(this, R.layout.singlerow,
 listItems);

 where R.layout.singlerow is:

 ?xml version=1.0 encoding=utf-8?

 TextView android:id=@+id/textInfo
xmlns:android=http://schemas.android.com/apk/res/android;
android:layout_width=fill_parent
 android:layout_height=wrap_content
 /TextView

 and my main.xml is:

 LinearLayout xmlns:android=http://schemas.android.com/apk/res/
 android
android:id=@+id/mainLinearLayout
 android:layout_width=fill_parent
android:layout_height=wrap_content android:padding=10px
ListView android:id=@android:id/list
 android:orientation=horizontal
android:layout_width=fill_parent
 android:layout_height=fill_parent
/ListView

 /LinearLayout

 Now my problem is: how can I add an image for each item in the list?
 I've tried a lot of solution, but all are not working. Please help me,
 I'm becoming craz!

 Thank you guys.

 I been working on an application that does that and attachments won't
 go through using the code referenced. I get a error saying that
 'multipart/mixed' isn't supported. The same code works like a champ in
 a non-Android app. Sounds like something is implemented yet.
