Probably not. Android mostly runs on low-power devices.

Talk to the i-Jetty people. Or use NanoHTTPD and embed your
server-side logic in their app code. Or try any one of the dozen or so
open source Java HTTP servers in existence. Or implement your solution
some other way that does not involve HTTP and servlets.

[android-developers] Re: Error inflating class linearlayout

[Bob Kerns]

No, that is perfectly legal. They're on separate elements. You can
declare the same namespace as many times as you want, with the same
prefix, or different prefixes. You can even declare it with different
prefixes on the same element (perhaps using one prefix for the
element, and another on attributes, or on children).

Re: [android-developers] Detect Intent Broadcast Receivers

[Dianne Hackborn]

PackageManager.queryBroadcastReceivers() returns all receivers declared in
application manifests matching a given Intent.  Note however that this will
not include receivers registered with Context.registerReceiver(); there is
currently no way to get information about those.

Specifically you'll want to use android:taskAffinity, perhaps
android:taskAffinity="" so that your configuration activity does not have an

[android-developers] Re: Conversion to Dalvik format failed with error 1

[sumanth]

Ok! I got it to work finally! (phew)

It turned out that the problem lay with my JRE. Android needs only
Oracle's JRE and my eclipse was pointing to IBM JRE.

I installed the JDK and pointed eclipse to the JRE in oracle's java
folder and the error was gone.

Hope this helps someone else in future.

This isn't Android weirdness, it's reality.  It's not like this is different
for other platforms -- consider the iPhone's HVGA vs "retina" displays.
 Same screen size, big difference in resolution.

This is just a fundamental aspect of mobile devices that developers coming
from PCs never think about, but need to get.  With PCs, generally screens
get bigger as the resolution increases in the density stays about the same.
 With mobile phones, the screen resolution and density has been quickly
increasing for the same approximate screen sizes.

This is a really good thing -- the PC world has wanted to move to higher
density screens for a long time, but it is very difficult because the
desktop platforms haven't had much support for different densities, and then
as the platforms started to take that into account you are still stuck with
tons of apps that don't work well when the density increases.

Don't make your app one of those on Android; our users' expectations here
are significantly higher than they have been on the desktop.

[android-developers] Re: supporting only resolutions >= 320x480

[Zsolt Vasvari]

Just coming from an end user -- I think I wouldn't be too happy not to
be able to play your game to its full pontential just because of the
resolution of my screen -- we are talking resolution here, not screen
size.  A 4" 480x800 device should display the same graphics (at a
lower resolution) than the same 4" with 240x400 resolution.

Re: [android-developers] Re: How to select a Contact Group, so not to create an "Invisible Contact" ?

[Dmitri Plotnikov]

If it is a Google contact, you need to find the system group called My
Contacts and add a group membership to the raw contact.  Of course this is
cumbersome, so in the future this will happen automatically, but for now you
need to do this in your code.

Re: [android-developers] About "?" in a URI

[Dmitri Plotnikov]

Hi Wenjie,

Looks like a bug.  I did not catch this because the contacts app and
provider run in the same process. I have just filed a bug report and will
research asap.  Of course, until it's fixed this API cannot be used. Thanks
for reporting.

Cheers,
Dmitri

[android-developers] Re: android bluetooth

[Jags]

Thanks a ton IV, I am happy as long as I get some relevant
solution :) .

1. Beep, means I did not mean default handset beep. I meant in my
custom application i play a sound. if my hedset is paired when i am
playing the sound in my custom application using Mediaplayer class,
will it be heard in my headset ?

2. will i be able to capture volume up/down key press in the headset
in my application ? if yes how ?

Yes - you'll want to create a custom Adapter that overrides the getView()

Don't use a Table.

Use a Weight on the RelativeLayout.

[android-developers] Notice: Holiday Post Moderation

[Trevor Johns]

Hey everyone,
Just a heads up that with the holiday season in full swing, most of Google's
engineering team will be on vacation. This includes those who
have volunteered their time to moderate this group.

I'll still be checking in on things, as will some of my colleagues, but
please don't be suprised if it takes a little longer than usual to get your
posts approved.

(And for those of you who don't know: Moderation normally only applies to
users who have never posted before. If you've been around for a while, your
posts will continue to flow without delay.)

Thanks for your understanding, and happy holidays!

The likelihood of anyone here not only having the code to solve your exact

give you said code is very near zero.

You would be better served by posting the stack trace of the error and the

[android-developers] Re: supporting only resolutions >= 320x480

[Utumno]

As you can see , I don't dig this 'density' Android weirdness too
much :)

No, as i said before: the bigger resolution, the better levels.
1280x600 ? Bring it on, baby! I've tested, the levels look and feel
great. I've tested 640x360, 480x854, what have you, all works great,
as long as it is >=320x480.  501x501? Very well!

I know I could detect at runtime if I have <320x480 and downscale the
graphics, but according to 
http://developer.android.com/resources/dashboard/screens.html,
the screen sizes that I don't support ( small screen + normal screen
with ldpi ) consist of 2.3+0.4% = 2.7% of all devices that contact the
Market, so quite frankly, I have simply decided not to bother.

So right now it looks like my best bet is to rule out the 240x320 guys
with 'smallScreens=false' and simply do not bother with 240x400 and
240x432  ( are there any devices with such weird resolutions in the
field anyway? There must be some as the link above gives 0.4%, but I
could not find any )

determine if call was really succeeded and how long it was - for
example, if called side was busy, it must remind later to call second
time.
In public API I found only
android.telephony.TelephonyManager.getCallState - but is seems that it
is unable to supply me with statuses DIALING, ANSWERED and BUSY. Is
there any way to get precise status of current call?

[android-developers] How to detect when bluetooth is turned on by user?

[martien huijsmans]

Hi,

I have a implemented a Android service which start a Bluetooth server.
This is based on the example "Connecting as a server" as found on
http://developer.android.com/guide/topics/wireless/bluetooth.html.

How can I detect if Bluetooth if is turned on by the user?
Is there a notification in Adroid that my service can subscribe to?
In my current implementation I periodically poll the BluetoothAdapter
as shown below
itsBTAdapter.isEnabled().

Regards Martien

[android-developers] EditText in Header of ListView loses focus after first character is entered

[Justin Glaeser]

Hello,

I have inflated a relativeLayout with a EditText inside and I am using
it as a filter for the list in the list header.

mListView.addHeaderView(searchBar, null, true);


Selecting the EditText causes the input to gain focus and the soft
keyboard to show itself; however, after entering in the first letter
the list is filtered, and the EditText focus is gone.  Typing other
characters has no effect on the input and I must reselect the input in
order to type the next letter.  Any suggestions on how the EditText
can keep the focus and received additional keys presses from the
keyboard?  Thanks.

[android-developers] The ulltimate Android development experience

[Kallex]

Dear fellow Android Developers,

We have discovered an industry breakthrough on software development,
that can make mobile development as simple as technically aware mobile
device user (yes, user, not a developer) can make full enterprise
scale application.

Note, despite being in alpha, this technology is reality.
Unfortunately though the toolset requires Visual Studio 2008+ right
now, but with the involvement from Google, this is trivial to change.
Also we have not yet published any reference abstractions, so it
requires in-project level abstractions currently. However once getting
used of the abstractions, their ROI is almost immediate even at
project level.

Currently all the Visual Studio using Android developers can start
abstracting and generating .java code from their abstractions. So fire
away if you have Visual Studio at your disposal.


The documentation is available here:

http://abstraction.codeplex.com/documentation


We are looking both for community participation as well as focus
interest on the larger industry player such as Google, Microsoft and
Nokia.

So if you love your Android over the other platforms, help us raise
the interest level so that Google executives get involved. If we do
not get their attention, the chances are that the focused case slips
on the other major vendors.

The full business case is available at:

http://citrusdevspot.spaces.live.com



Merry Christmas for all the fellow Androidians!

Kalle Launiala, CTO of Citrus Solutions Oy

[android-developers] XmlSerializer issue

[Batkhuu Regsuren]

I have the following code:

public void doSerialize() throws XmlPullParserException,
IllegalArgumentException, IllegalStateException, IOException   {
StringWriter writer = new StringWriter();
XmlSerializer serializer =
XmlPullParserFactory.newInstance().newSerializer();
serializer.setOutput(writer);
serializer.startDocument(null, null);
serializer.startTag(null, "START");
for (int i = 0; i < 20; i++) {
serializer.attribute(null, "ATTR" + i, "VAL " + i);
}
serializer.startTag(null, "DATA");
for (int i = 0; i < 500; i++) {
serializer.attribute(null, "attr" + i, "value " + i);
}

serializer.endTag(null, "DATA");
serializer.endTag(null, "START");
serializer.endDocument();

String xml = writer.toString(); // value: until 493rd attribute
int n = xml.length();  // value: 10125
}

The problem is that the serializer fails to serialize/write
everything. What could be possible reason? Any pointer would be
greatly appreciated.

Thank you in advance.

Rex

[android-developers] Detect Intent Broadcast Receivers

[Tao]

Hi,

A similar question has been asked before (with no answers as far as I
can tell), but I thought I'd try my luck: Does anyone know whether
there is a way to know whether there is anyone (anything) out there
listening for a specific type of Intent being broadcast?

There are numerous applications out there that listen for specified
intents, and do something when these intents are broadcast. For
example, "Last.fm Scrobbler" applications. I would like to be able to
tell, from a perferences screen, whether a given intent has a
registered Receiver or not.

This way, if a user chooses a scrobbler application and I detect that
that scrobbler application does not appear to be registered/listening
(or rather, there are no Receivers registered for that type of
Intent), then I display an error/explanation message to the user,
telling them that application is not installed or is disabled.

The closest I've come to this from looking at the Android dev docs is
"sendOrderedBroadcast". If the intended receivers of the broadcast can
be guaranteed to cooperate by doing something predefined to the
payload, then my broadcast receiver at the end should be able to
detect the successful receipt vs lack of Receiver... This relies on a
specific implementation on the part of the expected receivers,
however, so it's not a very general solution.

Any ideas?

Thanks!
Tao

[android-developers] JNI CallVoidMethod can t call

[TobyKaos]

Hello, I tried to communicate between C++ and Java with JNI.

I manage to execute test like HelloJNI in android-ndk.

I want my c++ native code call java function but when I debug my app I
have this JNI warning:
 "cant' call Lcom/project/teststl/TestSTL; .test on instance of Ljava/
lang/Class; "

my package is "com.project.teststl"
my java class is TestSTL and extends from Activity. in onCreate
function I call a native function write in c++ and all is ok.
In this native function I Find my class and GetMethodId without error.
But method CallVoidMethod crash. Why? must I create a thread and
getEnv?

Part of my native code:

jclass caller;


JNIEXPORT void JNICALL
Java_com_project_teststl_TestSTL_setCaller(JNIEnv* env, jobject obj)
{
if (env->ExceptionOccurred())
{
env->ExceptionDescribe();
__android_log_print(ANDROID_LOG_INFO, "test", "env null");
return ;
}
jclass localclass;// = (jclass)(env->GetObjectClass(obj));

localclass = env->FindClass("com/project/teststl/TestSTL");
if (localclass == 0)
{
__android_log_print(ANDROID_LOG_INFO, "test", "classe not 
found");

return ;
}

/* Create a global reference */
caller = (jclass*)(env->NewGlobalRef(localclass));

   // use of global reference
 jmethodID mid = (env)->GetMethodID( caller, "test", "()V");
  if (mid == 0) {
return;
  }

  /* The local reference is no longer useful */
(env)->DeleteLocalRef( localclass);

 // Here I have tried also with obj parameter

  env->CallVoidMethod( caller, mid);

}

any idea?

[android-developers] c2DM error when third-party server sends data to push

[nagaraj]

I am trying to push data from my server hosting a webservice but I get
the following error:



411 Length Required






Google  
 
Error
 

Length Required
POST requests require a Content-length header.







Here is the java code that posts message to google c2dm which inturn
will send a push notification to the device:


 private void postData(String auth, String id, String data) {
  DefaultHttpClient client = new DefaultHttpClient();
  HttpPost httppost = new HttpPost(
"https://android.apis.google.com/c2dm/send";);
  List formparams = new ArrayList();
  formparams.add(new BasicNameValuePair("registration_id", id));
  formparams.add(new BasicNameValuePair("data.payload", data));
  formparams.add(new BasicNameValuePair("collapse_key", "something"));
  //formparams.add(new BasicNameValuePair("Content-length",

   e1.printStackTrace();
  }
  httppost.setEntity(entity);
  Header header = new BasicHeader("Authorization: GoogleLogin auth=",
auth);
  Header header2 = new BasicHeader("Content-length=",
""+data.length());
  httppost.addHeader(header);
  httppost.addHeader(header2);
  httppost.getParams().setParameter("Content-length:",

  try {
   response = client.execute(httppost, localContext);
   HttpEntity entity2 = response.getEntity();

   System.out.println("");
   System.out.println(response.getStatusLine());
   Header[] headers = response.getAllHeaders();
   for (int i = 0; i < headers.length; i++) {
System.out.println(headers[i]);
   }
   System.out.println("");

   if (response.getEntity() != null) {
System.out.println(EntityUtils.toString(response.getEntity()));
   }

  } catch (Exception e) {
   System.err.println(e);
  } finally {
  }
 }

Note:
1.  I successfully got the registration id from the client (device)
2.  I successfully get the "Auth" from an earlier post on the server
side

Any help will be greatly appreciated

Thank you

[android-developers] Re: Anyone know where I can buy NFC tags?

[davidcinmidwest]

I purchased the "Tikitag" kit last year, which is now known as
touchatag referenced by Brill in this discussion.  The kit came with a
USB reader and 10 tags.  The tags are read-only.  Today the Nexus S
arrived and I'm happy to report that it reads the touchatags
successfully.  Passing the tag on the right side of the phone while
looking at the display produced:  "New tag collected" and a hyperlink
to a touchatag web site that displays Tag no. 0x...  Using the
touchatab dashboard, tags can be associated with a touchatag
application.  The Java JSR 257: Contactless Communication API has
details about the Java implementation of the NFC data exchange.  I
found some helpful code in 2009 on the Nokia web sites for the 6131
emulator, plan to look for that again as I test the Google
implementation.  Full Speed Ahead with Android 2.3 and the Nexus S!

[android-developers] SensorService has a bug related to Integer array conversion from C to JAVA

[JosephKim]

Hello,

I got a special concern about sensor service and sensor manager of
Android.
Recently I am trying to implement the sensor hal, and I found
susficious code
inside of android_open().


static jobject
android_open(JNIEnv *env, jclass clazz)
{


if (handle->numFds > 0) {
jobjectArray fdArray = env->NewObjectArray(handle->numFds,
gParcelFileDescriptorOffsets.mClass, NULL);

for (int i = 0; i < handle->numFds; i++) {
~~
}
// bundle.putParcelableArray("fds", fdArray);
env->CallVoidMethod(bundle,
gBundleOffsets.mPutParcelableArray,
env->NewStringUTF("fds"), fdArray);
}


if (handle->numInts > 0) {
jintArray intArray = env->NewIntArray(handle->numInts);

//@@@ WHY index is handle->numInts??? @@@
env->SetIntArrayRegion(intArray, 0, handle->numInts, &handle-
>data[handle->numInts]);

// bundle.putIntArray("ints", intArray);
env->CallVoidMethod(bundle, gBundleOffsets.mPutIntArray,
env->NewStringUTF("ints"), intArray);
}

// delete the file handle, but don't close any file descriptors
native_handle_delete(handle);
return bundle;
}

In this function, we want to copy fds array and then copy int arrays.
But in case of integer array, you need to focus on the start point of
data array.



You write code like

handle->data[handle->numInts]

I think It should be

   handle->data[handle->numFds]);


You might have mistake of starting point of data array to copy Integer
data.



Pls check it.
Let me know that it is correct or not

[android-developers] How to play radio station in android application?

[Siva]

Hi Friends,

I need to play a radio station in my application and that file format
is ".pls".

I tried by using VideoView and MediaPlayer and i cannot able to play
that station. I am getting "prepared failed" error.

Can you please explain how to play that .pls files in our android
application.

I thought Android SDK having some view or class to handle that. But,
unfortunately it does not have.. :-( :-(..

I have searched for all and still got any solution for this.

Any help or suggestion will be very much appreciated and helpful for
me

Thanks.

Re: [android-developers] Speed up showing Activity with ListView

[Kapil Lokhande]

Hi Johannes,

i think when your list data is in process fetch from server, you can create
your listview or other widgets on activity.only you have make sure after
thread which one fetching data from server will send message to your ui
thread about completion dat fetching. and then on resume you can call your
listview adapter notifydatasetchanged. and while your data fetching thread
is in progress you can show progress dialog.as far as i concerned this
solution will atleast show your list acivity loaded after progess dialog is
dissapear

[android-developers] Image doesn't appear from sqlite

[Amiral]

Hi all.

I would like to save an image from Internet to database, I've tried to
convert images into bytearray and store them in a database.

Here my code:

this is to created table:
myDB.execSQL("CREATE TABLE IF NOT EXISTS News (Title VARCHAR(20),
imageUrl BLOB, publishDate TIMESTAMP, expiredDate TIMESTAMP);");


and this is my Method to Insert table:

public void insertlistNews(String city,byte[] newsImageUrl, String
publishDate, String expiredDate){
try {
 myDB.execSQL("INSERT INTO News
(title,imageUrl,publishDate,expiredDate)"
+ " VALUES ('" + city + "','" + imageUrl + "','" + publishDate+
"','" + expiredDate"');");
Log.i("Android", "Table created");
} catch (Exception e) {
Log.i("Android", "No Table created" + e.getMessage());
}
//for check bytearray in database
Log.i("Android", "Image saved in database: "+ urlFrontImage);
}


The last my method for getNews from db:

public ArrayList getAllNews() {
 ArrayList news = new ArrayList();
 Cursor c = myDB.rawQuery("SELECT
title,imageUrl,publishDate,expiredDate
FROM News WHERE publishedDate <= DATETIME() and expiredDate >=
DATETIME() ORDER BY publishedDate DESC;", null);
 if (c != null) {
  c.moveToFirst();
  int count = 0;
  while (c.moveToNext()) {
   if (count == 0)
  c.moveToFirst();
   String title = c.getString(0);
   byte[] image = c.getBlob(1);
   String publishDate = c.getString(2);
   String expiredDate = c.getString(3);

   NewsItem nl = new NewsItem(title, image, publishDate, expiredDate);

   Log.i("Android", "Image get from db: "+image);
   news.add(nl);
   count++;
  }
 }
return news;
}


when I run it the newsimage not appear and the Log like this:

12-22 00:11:49.362: INFO/Android(307): Image saved in database:
[...@437cbdb8
12-22 00:11:51.052: INFO/Android(307): Image saved in database:

12-22 00:11:51.862: INFO/Android(307): Image saved in database:

12-22 00:12:07.962: INFO/Android(307): Image get from db: [...@4382d370
12-22 00:12:07.982: INFO/Android(307): Image get from db db:
[...@4382d9c0
12-22 00:12:07.992: INFO/Android(307): Image get from db: [...@4382e0e0

why results can vary between insert and getNews?

[android-developers] About "?" in a URI

[Wenjie]

Dear Dudes,
I've got an URI when I debugged the Contacts application. When the
application queries the contacts, it uses a URI like "content://
com.android.contacts/contacts?address_book_index_extras=true".
And if I query with this URI from an application based on SDK. It will
throw an exception like this,
"java.lang.UnsupportedOperationException: Only CrossProcessCursor
cursors are supported across process for now". But if the URI is
"content://com.android.contacts/contacts", it works well.
Can anyone show me what does the "?" mean here? And what's the
difference between the two queries by each URI?
Thanks very much!

I am jumping into android dev.  I am a web developer(.net) .  I
watched a pretty good video on android dev, but have a question I

Txt1 = (TextView)findViewById(R.id.Txt1);
//Initialize the text box

Txt1.setText(String.valueOf(score));

//Button Listeners

Btn1.setOnClickListener(this);
Btn2.setOnClickListener(this);
Btn3.setOnClickListener(this);



 }

@Override
public void onClick(View src) {
// TODO Auto-generated method stub

switch(src.getId())
   {
   case R.id.Btn_1:

  score++
   break;
   case  R.id.Btn_2:
   break;
   case  R.id.Btn_3:
   break;
 }
   }
}

My question is this.  The variable score seems to be out of scope in
the onclick function.  In fact, it will not compile and gives me an
error, but the instructor ran it no problem...and it seemed to me that
we had the same code.

Any Thoughts?

[android-developers] How to update one of views(setText, setImage) in item already added on ListView

[Mingchung]

Hi, all

* I have a ListView that using my layout document, to simplest, it
goes  like this ...


  
  
  


* then I populate the items to the ListView...
ListView lv = (ListView)findViewById(R.id.mylv);
ArrayAdapter aa = new ArrayAdapter(this,
R.layout.itemraw, R.id.tv_1, m_MyStringArray);
lv.setAdapter(aa);

* OK, the item is really populated like I think. Now I'd like to do
setText() to one of the TextView of one of ListView item...
LinearLayout ll = (LinearLayout)aa.getView(0, null, null);
TextView tv = (TextView)ll.findViewById(R.id.tv_3);
tv.setText("HAHAHAHAHA");

* Just like the program code, i set 3rd TextView with text "HAHAHAHA"
of first item, but nothing happened.

* My question is, an item has been already added to a ListView, can I
still update the UI?

There is no way to test xhdpi with emulator?

I am new to Android. I am trying to set up android on Linux system.

[android-developers] How to store images at runtime and then access it in a WebView throw a IMG tag ?

[Guillaume Lung]

Hi,

I'm looking to the group message but I can't find any answer to my
question. Maybe it is too basic...

- How to store images at runtime and then access it in a WebView throw
a IMG tag ?

[android-developers] Drawing text on a Bitmap (rather than Canvas)

[MichaelF]

(Cross-posted from StackOverflow:
http://stackoverflow.com/questions/4485587/drawing-text-on-a-bitmap-rather-than-canvas)

Hi,

I am drawing some text on a Canvas, and on a Bitmap, respectively:

protected void onDraw(Canvas canvas) {
canvas.drawText("Canvas text", 10, 10, mPaint);
Canvas singleUseCanvas = new Canvas();
singleUseCanvas.setBitmap(mBitmap);
singleUseCanvas.drawText("Bitmap text", 10, 30, mPaint);
}

In the former case, the text renders as you would expect, while in the
latter, it appears very rough and ugly. This becomes even more
problematic when using e.g.

canvas.drawBitmapMesh(...);

to apply transformations to the bitmap. Am I doing something wrong, or
is the quality simply deteriorated when you pass from Canvas to
Bitmap?

On a side note, the reason why I'm drawing text on a Bitmap is to
obtain a "magnifier" effect on the text in question (like Apple OSX's
dock), since I can then apply arbitrary transformations to it using a
bitmap mesh. Is there another, perhaps better, way to do this?

Best,

Michael

[android-developers] Problem connecting to WIFI network

[Soprano]

Hello,

I've a Samsung Galaxy Tab, Android Froyo, Vofafone firmware
P1000BUJI5.

I'm connecting to a wireless router which I have no direct access to
(it's in a neighbor building, they just told me the wpa password). The
first day I had no problem to connect to the network, but since then I
was not anymore able to connect. The system holds on the "obtaining IP
address" message, then after a few minutes rescans and again the same
message.

At the same time, I'm able to connect without problems using my laptop
(Ubuntu 10.04) or my mobile phone (Nokia E71).

Looking around on the web it seems this problem happened to many other
users, is it somehow addressed ?

thanks.

[android-developers] Image does't appear from sqlite

[Muhammad Amiral]

Hi all.

I would like to save an image from Internet to database, I've tried to
convert images into bytearray and store them in a database.

Here my code:

this is to created table:

> myDB.execSQL("CREATE TABLE IF NOT EXISTS News (Title VARCHAR(20), imageUrl
> BLOB, publishDate TIMESTAMP, expiredDate TIMESTAMP);");



and this is my Method to Insert table:

public void insertlistNews(String city,byte[] newsImageUrl, String
> publishDate, String expiredDate){

try {

 myDB.execSQL("INSERT INTO News (title,imageUrl,publishDate,expiredDate)"

  + " VALUES ('" + city + "','" + imageUrl + "','" + publishDate+ "','" +
> expiredDate"');");

Log.i("Android", "Table created");

} catch (Exception e) {

Log.i("Android", "No Table created" + e.getMessage());

}

//for check bytearray in database

Log.i("Android", "Image saved in database: "+ urlFrontImage);

}



The last my method for getNews from db:

public ArrayList getAllNews() {

 ArrayList news = new ArrayList();

 Cursor c = myDB.rawQuery("SELECT title,imageUrl,publishDate,expiredDate

FROM News WHERE publishedDate <= DATETIME() and expiredDate >= DATETIME()
> ORDER BY publishedDate DESC;", null);

 if (c != null) {

  c.moveToFirst();

  int count = 0;

  while (c.moveToNext()) {

   if (count == 0)

  c.moveToFirst();

   String title = c.getString(0);

   byte[] image = c.getBlob(1);

   String publishDate = c.getString(2);

   String expiredDate = c.getString(3);


>NewsItem nl = new NewsItem(title, image, publishDate, expiredDate);

   Log.i("Android", "Image get from db: "+image);

   news.add(nl);

   count++;

  }

 }

return news;

}



when I run it the newsimage not appear and the Log like this:

12-22 00:11:49.362: INFO/Android(307): Image saved in database: [...@437cbdb8

12-22 00:11:51.052: INFO/Android(307): Image saved in database: [...@437db710

12-22 00:11:51.862: INFO/Android(307): Image saved in database: [...@437c1338


> 12-22 00:12:07.962: INFO/Android(307): Image get from db: [...@4382d370

12-22 00:12:07.982: INFO/Android(307): Image get from db db: [...@4382d9c0

12-22 00:12:07.992: INFO/Android(307): Image get from db: [...@4382e0e0


why results can vary between the insert and getNews?

[android-developers] Strategy for animating a circle

[Citizenfish]

I am getting into development and am looking to create a class that
will draw a circle of radius X which will expand to radius Y and then
start again at X. I am assuming that a canvas is the best object to
use to render this but what is the best strategy to carry out the
animation?

I really want it to be smooth and independent of other screen events.

Dave

[android-developers] At wits end: Windows Vista does recognize Adroid usb driver

[Leo]

I am connecting a Huawei Ideos S7 Tablet to my 32 bit Windows vista
machine in order to do "on device" development. As soon as I plug it
into the computers USB port I get the add new hardware dialog box,
which eventually tells me it can't find the driver. At that point I
use the menus to eventually make my way to the "browse your computer
for the driver" option and at that point I point windows to the
location of the usb driver that I downloaded via the Android SDK
manager. Unfortunately windows comes back and says it can't find the
driver in that director.but it's there

Is the Android USB driver generic for any device that uses android, or
are there different drivers for different hardware?

It would seam to me that windows should at least recognize the
extension as a driver and move to the next part of the installation
but not even that happens.

I have tried installing from device manager and i get the same
message.

Extra INFO
I can see the tablets USB drives (two of them for some reason???)
mounted but when I click them I get a "please insert disk into a
removable disk drive letter" message. This might or might not be
normal behavior for this device since there is not a Micro SD card
installed in the slot, though I would have thought that I would have
been at least able to see internal memory.

I have enabled USB debugging on the device. I have tried numerous
solutions found on this forum and others, though none of them address
the specific issue that Windows vista refuses to recognize the android
driver.

The tablet is running Android 2.1-update 1

Does anyone have Any ideas before I throw this tablet back to Korea.
ANY help would be appreciated!

[android-developers] BACK key does not finish activity

[dev777]

Hi,

I am running a service that starts a new activity when specific
applications are launched.

For example, when I launch sms application, my service detects it by
checking a top activity package name and starts a new activity.

But the problem is that after starting a new activity, when I finish
that activity and press BACK button from sms application to go back to
Home screen, it does not finish my sms application.

Even though the screen is at home(launcher), when I check top activity
name, sms app is running as the top activity, which means sms app is
not finished after pressing BACK button.

I use Intent.FLAG_ACTIVITY_NEW_TASK intent flag for starting a new
activity and finish() to finish it. Does anyone have an idea why my
BACK button does not finish sms application in this case?

thanks,

777

[android-developers] call c++ function with jni and android ndk

[TobyKaos]

Hello, I first run samples found in androind ndk and I create my own
in C. I successfully print a hello world with c function.

but now I want to call c++ function. Then I change file extensions
to .cpp and remake with ndk-build. Ok that seems to work fine. I
refresh my eclispe project. Ok eclispe seems to find my hello world
function in new .so lib made in c++.

Then I launched debug and application failed because it does not find c
++ function. My function is the same but I modify jni function in it
to match c++ jni.

My TestSTL.java

package com.project.teststl;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class TestSTL extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.main);

TextView  tv = new TextView(this);
tv.setText( stringFromJNI() );
setContentView(tv);
}

native public static String stringFromJNI();

static {
//System.loadLibrary("stlport_shared");
System.loadLibrary("teststl");
}

}

*
my test.cpp file

#include 
#include 

#include 
#include 

/* Call to initialize the graphics state */
JNIEXPORT jstring JNICALL
Java_com_project_teststl_TestSTL_stringFromJNI(  JNIEnv* env, jobject
obj  )
{
jstring s = (env)->NewStringUTF( "Hello from JNI !");

return s;

}



I repeat, in C all is ok (I just modify NewStringUTF for C or C++
because are not the same definition).

Please help me.

[android-developers] Split screen om android

[irulz]

Hi Friends

I would like to support split (dual) screen on the android.

Split Screen: Two apps with different resolution can run
simultaneously.
I would like to keep one physical display and two logical
display(surface).

I know its not a trivial change and will really need some effort.
I am trying to get a highlevel picture of the changes required.

In my opinion the main components which will be modified are:

1. Activity manager  -- Changes to support two activities
2. Windows Manager -- Support two activity stack, two windows stack
and two application stack
3. Surface flinger 
4. Driver changes 

Do I need to have any changes in surfaceflinger ?
Any changes in driver? Any changes in OpenGL/EGL ?

I will really appreciate any input on this. Is thr anything I am
missing ?

Also I am looking for a doc on flow diagram from activity manager-
>windowsmanager->surface flinger (call flow diagram) or some good
document. Any pointers? I tried to google but could not find detailed
doc.

Thanks

But I want to host Apache Tomcat where I will also be having the Java

Re: [android-developers] Re: supporting only resolutions >= 320x480

[Dianne Hackborn]

That just isn't how it works.  A 240x400 ldpi screen should be treated as
the *exact* *same* space as a 320x533 screen which should be treated as the
*exact* *same* space as a 480x800 screen.

The only difference is density, which means less or more graphical detail.
 Not UI/level complexity

You shouldn't be making your level complexity more complicated due to
changes in density.  Taking an extreme -- from ldpi to xhdpi -- this would
result in a UI so tiny (but with a ton of stuff on it) at xhdpi that it is
impossible to use or possibly even see.

This is the reason why we split things between density and screen size.
 They are fundamentally different things, and you need to take both into
account.  As I said, the platform already has various facilities to scale
graphics for you, but if you need to it is pretty easy to do yourself -- if
you are using OpenGL you could probably just do it at runtime; otherwise,
it's just a matter of generating a new bitmap with the scaled image and
throwing away the original.

That's rare enough to be noteworthy when it happens. And to be fair, I

But I'd be more interested in a commitment to doing something about
it. Unfortunately, it's already too late for many, if not most, of us.

[android-developers] Re: SDK 2.3: Get "Multiple substitutions specified in non-positional format" error

[Bob Kerns]

Um, no, on this point. Implicit indexing vs explicit indexing is still
ALWAYS exactly the same order.

When you use implicit ordering, say "%s %s", this is always, ALWAYS,
exactly equivalent to "%1$s $2$s". The latter adds NO INFORMATION
WHATSOEVER, and does not remove any ordering dependency. The order of
the ordinals, and the implicit ordering, are both inextricably tied to
the ordering in the code. Now, if %1$s is an adjective, and %2$s is a
noun, and you translate to Spanish, you would have to reverse the
order, and use "%2$s %1$s", but that translation is ALSO tied to the
specific ordering in the Java code.

Not using indexed substitutions in a library resources is NOT A BUG.

I can't even make a decent case, despite seriously trying, for why you
should even PREFER to write "%1$s %2$s" over "%s %s". The closest I
can come boils down to, "it's educational!".  And that leads me to the
position that THIS SHOULD NOT EVEN BE A WARNING! (And yes, ALL CAPS
means I AM YELLING!)

The real issue here that Ecthelion is raising is that if you are
mistaken about HOW a string is used, and it is not passed to
String.format, and you introduce the explicit ordinals, then you have
INJECTED A NEW BUG, just to shut up the resource compiler.

(And if you use %n, and you shut up the resource compiler, then you
have INJECTED A NEW BUG, because String.format does not support that,
regardless of what the resource compiler may think!)

In short, this change fixes NO bugs, but does cause or even force
developers to inject new ones. I'm glad I thought to test for %1$n,
rather than blindly accede to the resource compiler's demands!

[android-developers] Re: supporting only resolutions >= 320x480

[Utumno]

Because I don't scale my graphics , and I don't let the system do it
either :)

My reason: actually I could make the UI work in 240x400 and 240x432,
the problem is with game area.
The app is a game where infinitely many levels are created pseudo-
randomly. The bigger resolution, the more complicated and generally
speaking better levels get created. At 320x480, the game is playable,
at 480x800 , it is excellent and I DONT want to upscale the graphics
because that would simplify the levels back to more or less 320x480
level, thus making the game worse.

On 240x320, I still could make the game work by downscaling the
graphics, but how do I do it? Then I would have to

- downscale on 240x320, 240x400 and 240x432
- do *not* resize on >=320x480

If I can do the above, then excellent, my game would work everywhere.
If not, I have to somehow rule out all the resolutions smaller than
320x480.

[android-developers] Re: SDK 2.3: Get "Multiple substitutions specified in non-positional format" error

[Bob Kerns]

Sorry for the delayed response; I missed seeing your reply until now.

I wasn't asking about plurals. I was commenting that having them as a
string resource but not integrated with the format system is a FAIL,
when you consider the actual translation workflow and lifecycle,
because using them requires a coding change.

But, on those occasions where you are dealing with one language, or
carefully work out IN ADVANCE how to make it all work out with
multiple languages (i.e. supply plurals for every possible argument
that might need them, as an additional argument, and sorting it all
out with positionals in the format string) -- on those occasions, it's
nice to have. Of course, you could have done the same thing with a
string array, but it captures the intent more nicely.

But it does require the programmer to know a lot about translation,

Re: [android-developers] supporting only resolutions >= 320x480

[Dianne Hackborn]

Why would it not work on 240x400?  That is just a density change; if you
don't scale your graphics, the platform can do it for you.

Re: [android-developers] Re: Cannot define a float as a resource?

[Dianne Hackborn]

It definitely works; after all, this is how activities are full-screen.

If nothing else, you can just set the theme of your dialog to @style/Theme
which will make it look and behave the same as a full-screen activity. ;)

Be sure that you are setting this on the *window* not on the content view.
 A WRAP_CHILD in a parent will cause its children to wrap as well; by
default a dialog as WRAP_CHILD for the width and height of the entire
window.  You change this with Dialog.getWindow().setLayout().

[android-developers] Re: Cannot define a float as a resource?

[Zsolt Vasvari]

Hi Dianne,

I have never been able to successfully make MATCH_PARENT work.  It
seems to work for making the width (but not the height) of a floating
Activity match the screen size, but I was never able to do the same
for an AlertDialog.

Here's an AlertDialog from my app using MATCH_PARENT for the
AlertDialog's content view.  No views inside have a specific size set:
http://picasaweb.google.com/zvasvari/ScreenWidth#5554064956779202578

As you can see, it's way too narrow for the screen and, of course,
it's even worse in landscape mode.

Now here's the same dialog if I give it a minWidth of 300dp, nicely
filling the screen.  This is on a Nexus One (480x800):
http://picasaweb.google.com/zvasvari/ScreenWidth#5554064961041980722

I've tried many-a-times in vain to make an AlertDialog expend to the
screen size, but so far, I've been unsuccessful without giving it a
minWidth.

[android-developers] supporting only resolutions >= 320x480

[Utumno]

Hello Android gurus,

My app only works in phones with screen resolution >= 320x480. More
precisely: it knows how to render itself correctly on any resolution
where the longer side is>=480 and the shorter side is >=320, no system
prescaling is needed, but anything less than 320x480 is simply too
small to cram my UI in.

What exactly do I put in my manifest to rule out phones with lower
resolutions?

Now, according to Table 1. from 
http://developer.android.com/guide/practices/screens_support.html,
I could rule out the 240x320 resolution with

anyDensity=true
smallScreens=false
normalScreens=true
largeScreens=true
xlargeScreens=true

but that is not going to rule out the '240x400' and '240x432'
resolutions which apparently are considered 'normal screens' . That
sucks!

[android-developers] Re: Determining which pointer is moving

[Paul]

Thanks Diane, yes I am using a 'slop' threshold for movement as it is
basically impossible to 'not move'.  In terms of comparing the
previous location for each pointer, is looping through the passed
MotionEvent and comparing each pointer location with a previously
stored event (stored in some private field) the 'way' to do this?
Just getting my head around all the ins and outs of handling multi-
touch, and want to ensure I am tackling these things in the best way
(have to essentially store my own location history data due to the
fact that HistoricalX, Y data is related to some previous MotionEvent
rather than the previous location data for a pointer in the current
event, correct?)

[android-developers] Market in U.K. not up to date?

[Doug Gordon]

According to one of my users in the U.K. (I'm in the U.S.), my app is 
still showing a version that's at least two weeks old in the Android 
Market that he has access to. Is there any particular reason for this? 
It's causing some grief since he could really use the update. I'm also 
surprised that I haven't heard of this from any other users (or maybe 
they're just not aware that an update is available).

[android-developers] How to update particular widget instance in reaction to its inside button click

[aleksej]

Hello,

I have an application widget which include text and button views. I
create 2 instances of my widget on home screen. I'd like to differ
button clicks depending on particular widget instance it contains and
update appropriate text view only. How could I achieve this behavior?

My steps so far:

1. Created AppWidgetProvider
onUpdate(Context context, AppWidgetManager appWidgetManager, int[]
appWidgetIds) {
  for (int widgetId: appWidgetIds)
startUpdateService(widgetId, "initial text");
}
onReceive(Context ctx, Intent intent) {
  int widgetId =
intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, -1)
  if (DO_UPDATE_TEXTVIEW.equals(intent.getAction()))
 startUpdateService(widgetId, "refreshed text");
  }
  startUpdateService(int widgetId, String text) {
 Intent intent = new Intent(context, UpdateService.class);
 intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, widgetId);
 intent.putExtra(TEXT, text);
 context.startService(intent);
  }
2. Created IntentService
   public void onHandleIntent(Intent intent) {
 int widgetId =
intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, -1);
 String text = intent.getStrintExtra(TEXT);
 RemoteViews views = new RemoteViews(this.getPackageName(),
R.layout.widget);

 PendingIntent pIntent = PendingIntent.getBroadcast(this, 0, new
Intent(DO_UPDATE_TEXTVIEW), 0);
views.setOnClickPendingIntent(R.id.button, pIntent);
views.setTextViewText(R.id.text, text);
AppWidgetManager wdgManager = AppWidgetManager.getInstance(this);
wdgManager.updateAppWidget(widgetId, views);
 }

The problem is in onReceive() method, actually. widgetId, that I'm
getting from Intent is not correct (always the same value;) not
appropriate widget id, on which my button click really happen. 
Would appreciate any help. thanks.

[android-developers] AnimationListener.onAnimationRepeat never gets called

[John Lussmyer]

Since I finally have my simple animation repeating (by working around a bug
in Android), I get to run into the next problem.
AnimationListener.onAnimationRepeat() never gets called.
I use a button to start my animation, let it run a while, and press the
button again to stop it.
Since I want to do some things synchronized with the animation, I setup an
animation listener.
It doesn't work.  Here is the main code:

private Animation.AnimationListener mAnimationListener = new
Animation.AnimationListener() {

public void onAnimationStart(Animation animation) {
scnt++;
}

public void onAnimationRepeat(Animation animation) {
rcnt++;
}

public void onAnimationEnd(Animation animation) {
ecnt++;
}
};

private OnClickListener mClickButton = new OnClickListener() {
public void onClick(View v) {
Button button = (Button) findViewById(R.id.Button01);
if (running) { // Currently running, stop it
//button.setText(R.string.Button01);
testShape.clearAnimation();
button.setText("repeat " + scnt + "," + rcnt + "," + ecnt);
} else { // Currently stopped, start it
button.setText(R.string.BtnStop);
testShape.startAnimation(testAnimation);
}
running = !running;
return;
}
};

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button) findViewById(R.id.Button01);
button.setOnClickListener(mClickButton);
testShape = (TextView) findViewById(R.id.TextView02);
testAnimation = AnimationUtils.loadAnimation(this,
R.anim.bounceanim);
testAnimation.setAnimationListener(mAnimationListener);
testAnimation.setDuration(1000);
return;
}


When the app is run, and the button pressed:
the animation starts running.
I let it run for several cycles and press the button again.
The result is "repeat 1,0,1" - showing that the onAnimationRepeat() was
never called.

Is this a bug, or am I missing something?
