import java.util.ArrayList;
import java.util.HashMap;



import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ListAdapter;
import android.widget.SimpleAdapter;





public class Activityinstaforexquotes extends ListActivity {
  
 // All static variables
static final String URL = url;
// XML node keys
static final String KEY_item = item; // parent node
static final String KEY_symbol = name;
static final String KEY_BID = middlename;
static final String KEY_ASK = surname;

setContentView(R.layout.activity_activityinstaforexquotes);

ArrayListHashMapString, String menuItems = new 
ArrayListHashMapString, String();

quotesXMLParsing parser = new quotesXMLParsing();
String xml = parser.getXmlFromUrl(URL); // getting XML
Document doc = parser.getDomElement(xml); // getting DOM element

NodeList nl = doc.getElementsByTagName(KEY_item);
// looping through all item nodes item
for (int i = 0; i  nl.getLength(); i++) {
// creating new HashMap
HashMapString, String map = new HashMapString, String();
Element e = (Element) nl.item(i);
// adding each child node to HashMap key = value
map.put(KEY_name, parser.getValue(e, KEY_name));
map.put(KEY_middlename, parser.getValue(e, KEY_middlename));
map.put(KEY_surname,  parser.getValue(e, KEY_surname));

// adding HashList to ArrayList
menuItems.add(map);
}

// Adding menuItems to ListView
ListAdapter adapter = new SimpleAdapter(this, menuItems,
R.layout.showquotes,
new String[] { KEY_name, KEY_middlename, KEY_surname }, new int[] {
R.id.namel, R.id.middlename, R.id.surname });

No one is going to download a RAR file from you and weed through your code
to fix your problem. Try posting a relevant code sample and explaining your
problem better. Details like what device you're running on and what version
of Market you're running would help, for example.

[android-developers] Please Help...Android 4.0.3 WebView Crash...

2012-06-19 Thread Tommy Hartz

Hi,

 

On android 4.0.3 I have an Activity that contains a webview. This webview
loads a Google Maps webpage that is stored on our servers. The Map is
overlaid with a Radar.

 

When I double tab to zoom in on the map my app crashes. It is crashing and
gives me an error com.android.launcher/com.android.launcher2.Launcher
(server)' ~ Channel is unrecoverably broken and will be disposed!

 

Does anyone have any idea why this is happening? It seems to work fine on my
phones 2.3.3 and 2.3.4 as well as a few other devices that I have tried it
on. The table however is the one giving me the issue. It is an Acer A200

 

Thank you for your time,

 

Tommy

Unless you decided to name your app com.android.launcher, this message

2012-06-19 Thread Tommy Hartz

That's the weird part, it happens inside my app but I assume if it was a
problem with my app it would happen on all devices. It seems like it might
be a bug with WebView on 4.0.3 I was kind of hopeing someone else has seen
the issue or knows about it. It only happens when I try to zoom in on the
Google map that is inside the WebView.

Re: [android-developers] Please Help...Android 4.0.3 WebView Crash...

If it is crashing (as in you get a Force Close-style dialog), there
should be a Java stack trace at the end of your LogCat associated with
that crash.

[android-developers] Please help about Renderscript compute

2012-04-16 Thread Booker

Hi, all.

I am a newbie of Android development and I am developing an app for
image processing and I ported some filters to android.

However, the performance is not good and I read some articles pointing
renderscript is one of the way to boost performance.

I read some codes but I find it too difficult for me to understand.

I have a edge detection filter implemented in JAVA and I would like to
port it to RS.

I have read the Helloworld Compute code and I can see the root() is
processing one pixel each time and unpack it into a float4 variable.

However, in my code, I need to read not only one pixel data but
several to calculate the result and I use 2D array to store the
values.

How can I implement this in RS, computing more than one pixel in the
same time?

[android-developers] Please Help me! I have SQLiteDatabaseCorruption Error

2012-03-13 Thread Halil Enver Soylu

I have a 5MB database. I split it into 1MB chuck files.
application merges these files and creates its database. 

However it works in some Android phones, and does not works in others. I 
tried almost dozen of code example in blogs. everytime I got same result.
App's platform vers. is 1.5 so it is not about platform vers.

According to logs of phones that application crushs, app creates copies db 
file from Assets to database. then when it attempts to get a query for the 
first time, it crushs and gives that error:

03-11 01:11:34.111 I/Database( 4516): sqlite returned: error code = 11, msg = 
database corruption at line 46886 of [42537b6056]

and here is my codes that copies asset files into database


String[] dbFiles = myContext.getAssets().list(ASSETS_DB_FOLDER);
OutputStream myOutput = new FileOutputStream(DB_PATH+DB_NAME);
 for(int i =0; i  dbFiles.length; i++) 
{
Log.i(FFLOG,COPYDB:+dbFiles[i]);
InputStream myInput = 
myContext.getAssets().open(ASSETS_DB_FOLDER+/+dbFiles[i]);
byte[] buffer = new byte[1024];
int length;
while ((length = myInput.read(buffer))  0) {
myOutput.write(buffer, 0, length);
}
myInput.close();
}
myOutput.flush();
myOutput.close();

please help me
if there were a problem about database file or query SQL code, it would not 
work in some phones. So, it is not about db file or query. I am looking for 
a solution for 2 weeks please help me

[android-developers] please help to find out deleted or updated contact in android device contact list

2012-02-15 Thread vijay kher

Hi ,

I wants to get contact that is either deleted or updated by user in device 
contact list.

For that i have try with content observer and notice that its onChange() 
method is called  with one boolean parameter when any contact is added or 
deleted.But does not give any information regarding that contact.

So is there any listener in android for getting contact information that is 
either deleted or updated by user in device contact list or any action 
fired from system.

Thanks in advance,

Re: [android-developers] please help to replace lock screen theme

2012-02-05 Thread Kristopher Micinski

You can't directly do this.

You can only replace the lock screen.

http://thinkandroid.wordpress.com/2010/01/24/handling-screen-off-and-screen-on-intents/

http://stackoverflow.com/questions/6737760/android-lockscreen-tutorial

http://stackoverflow.com/questions/5529608/android-how-to-develop-custom-lock-screen

Basically the answer is: don't do this.  If you do this, your app is
basically, violating a security hole in the android system.  The behavior
that older lock screen apps use is not good practice, and will be (if it
has not already been) removed from the API so your app will cease to work.

Perhaps you think but my app is special.

Answer: no, it's not.

Perhaps you think but only I will ever use my app, so I don't mind if it
breaks good coding practices, might be removed from the market for
violating security practices (highly unlikely..), and uses now considered
deprecated pieces of the API.  Well, then perhaps the answer is to go
right ahead.

In general if you're wanting to modify the behavior of the *system*, you
can't do it with an app.

 Basically the answer is: don't do this.  If you do this, your app is
 basically, violating a security hole in the android system.  The behavior
 that older lock screen apps use is not good practice, and will be (if it
 has not already been) removed from the API so your app will cease to work.

 Perhaps you think but my app is special.

 Answer: no, it's not.

 Perhaps you think but only I will ever use my app, so I don't mind if
 it breaks good coding practices, might be removed from the market for
 violating security practices (highly unlikely..), and uses now considered
 deprecated pieces of the API.  Well, then perhaps the answer is to go
 right ahead.

 In general if you're wanting to modify the behavior of the *system*,
 you can't do it with an app.

Re: [android-developers] please help to replace lock screen theme

2012-02-05 Thread Kristopher Micinski

Trust me... you can't do this...

I've been through the SDK, so have many other people on the list,
especially Mr. Murphy (one of the people answering the posts on SO). If
there had been a way to do it, he would have told you.

Re: [android-developers] Please help me!!! how to create video file on server side by send onPreviewFrames byte array

Use any one of the numerous methods to send the files to your server (HTTP,
FTP etc). You can use something on the server to combine them into a video.
What you do on the server is not part of the Android SDK, and hence doesn't
belong on the list.

What do you mean by not working? Are you getting a specific error? What

Also, in my personal opinion, it would be easier to send the images via
HTTP or FTP.

I didn't quite understand your explanation. From what I get, you are saving
images to the SD Card, and then send those images in a byte array to your
server and want to save it as a video file? From what I have learnt so far
in this world, image files don't arbitrarily convert themselves to video
files. It would be easier for you to record the entire video and then send
it after the recording has finished to the server.

this to server is not working.
/// Here is  my client side code

 public void onPreviewFrame(byte[] data, Camera camera) {  // 11

Camera.Parameters parameters = camera.getParameters();
int format = parameters.getPreviewFormat();

 //YUV formats require more conversion
if (format == ImageFormat.NV21 /*|| format == ImageFormat.YUY2 ||

{
int w = parameters.getPreviewSize().width;

int h = parameters.getPreviewSize().height;
// Get the YuV image
YuvImage yuv_image = new YuvImage(data, format, w, h, null);

RE: [android-developers] Please help me!!! how to create video file on server side by send onPreviewFrames byte array

2011-11-27 Thread lbendlin

It might be overly ambitious to send uncompressed frames to the server. You can 
compress them to Jpeg in memory and send these to the server via whatever 
method. On the server concatenate the files to a MJpeg stream.

RE: [android-developers] Please help me!!! how to create video file on server side by send onPreviewFrames byte array


Thanks for your reply.First,is it good way to create a video(Mjpeg) from jpeg 
images? Secondly, In my code i compress camera onpreviewframe byte array to 
jpeg format and its perfect but when i send this compressed byte array to 
server through TCP socket and server save it in a file, but not in correct 
format.
 
 
/// Here is  my client side code
 public void onPreviewFrame(byte[] data, Camera camera) {  // 11

Camera.Parameters parameters = camera.getParameters();
int format = parameters.getPreviewFormat();

 //YUV formats require more conversion
if (format == ImageFormat.NV21 /*|| format == ImageFormat.YUY2 || 
format == ImageFormat.NV16*/)
{
int w = parameters.getPreviewSize().width;
int h = parameters.getPreviewSize().height;
// Get the YuV image
YuvImage yuv_image = new YuvImage(data, format, w, h, null);
// Convert YuV to Jpeg
Rect rect = new Rect(0, 0, w, h);
ByteArrayOutputStream output_stream = new 
ByteArrayOutputStream();
yuv_image.compressToJpeg(rect, 100, output_stream);
byte[] byt=output_stream.toByteArray();

FileOutputStream outStream = null;
try {
 /// this work perfect for sd card
//outStream = new FileOutputStream(String.format(
///sdcard/%d.jpg, System.currentTimeMillis()));
//outStream.write(byt);
//outStream.close();

// this method write byte array to socket
sendBytes(byt, 0, byt.length);
Log.d(TAG, onPreviewFrame - wrote bytes: 
+ data.length);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();

IOException {
if (len  0)
throw new IllegalArgumentException(Negative length not allowed);
if (start  0 || start = myByteArray.length)
throw new IndexOutOfBoundsException(Out of bounds:  + start);
// Other checks if needed.

// May be better to save the streams in the support class;
// just like the socket variable.

DataOutputStream dos = new DataOutputStream(socket.getOutputStream());
//BufferedOutputStream imagebos = new BufferedOutputStream(dos);  
 
   dos.writeInt(len);
if (len  0) {
   /// this will write to socket
imagebos.write(myByteArray, start, len);


}
}



//here is server side code  /


 while(dataInputStream.readInt()  0 )
{
    reading from client
   
   
   read from client in byte array 
   
int len = dataInputStream.readInt();
byte[] data = new byte[280];  
how to specify the length in run time 
if (len  0) 
{
dataInputStream.readFully(data);
//dataInputStream.read(data);
System.out.println(message:  + data);
}

 write this data array on a file

FileOutputStream fos = new FileOutputStream(image.jpg, true);
ObjectOutputStream out = new ObjectOutputStream(fos);

out.write(data);
out.flush();
out.close();
fos.close();  
 
}

the server side code is correct or not but the file is not in correct formate, 
please tell me if i am doing wrong. Also tell me is it correct method to 
combine the images file to create a video?
Please correct me if i m doing wrong


Thanks 
umer
