Search for 'password based encryption'. There are standard algorithms to
derive a key from a password securely. For Java, you might want to use
'PBKDF2WithHmacSHA1' or some equivalent available on Android.

Re: [android-developers] Re: ListView - is it possible to limit the fling speed?

2011-05-10 Thread Omar Adobati

than to all the guys who have been replying to me,

So, I have understood I can't limit the speed the fling scroll, but it would
be at least possible to stop the scroll when I do touch the list? As I
wrote, when I do perform a scroll that then come up to be a fling my list
scroll to the top or the bottom (depending by the direction I do the
movement) without having the chance to stop it.

Thanks,

Omar

Re: [android-developers] Data transfer from WindowManagerService.java to WindowManager.java

2011-05-10 Thread Dianne Hackborn

You can't do that -- WindowManagerService has an array of WindowState
objects, which only inside its process.  A Window object only exists inside
of the process of that window, and the window manager services knows nothing
about it.  Further, there is no direct association between a window in the
window manager and a Window object, in fact not every window has a Window
object.

Please direct further questions to android-platform or android-porting, I
won't respond any more since this is not about developing applications
against the SDK.

Re: [android-developers] Re: ListView - is it possible to limit the fling speed?

When the user presses on the screen during a fling it stops the screen.
 This is how list view and other scrolling containers have always working in
Android since 1.0.

[android-developers] Not finding proxy and port values in the settings.db (Gingerbread)

2011-05-10 Thread Ashok Jeevan

Hi All,

I was trying to add the proxy and the port from the APN settings. After
pulling the settings.db, I found that the proxy:port values had not been
inserted in the 'secure' or 'system' table.

I looked in the above two tables since a lot of web queries showed the query
to insert the values into the mentioned tables.

On probing the source of Gingerbread, I found out that the values are being
stored in the com.android.providers.telephony/telephony.db

Is this a change in the Gingerbread or am I getting my research wrong?

[android-developers] Re: Delete all rows from a table throws nullpointer

2011-05-10 Thread Capt Spaghetti

So the basic question remains the same. How do I delete everything in
a table without dropping and
re-creating the table?

Thanks

  I have also tried the following:

Re: [android-developers] Re: Delete all rows from a table throws nullpointer


You call

db.delete( table name here, null, null);

If the value of db is null, you will get a NullPointerException, just 
like for any other method invocation on a null object, database or not.


Check to see where you get the value of db from, and fix it so that 
db actually is a valid database object.

Re: [android-developers] Re: Export contact to vCard


Have you looked at the vCard format specs?

http://en.wikipedia.org/wiki/VCard

http://tools.ietf.org/html/draft-ietf-vcarddav-vcardrev-19

Even if the library you're using doesn't directly support the items you 
wish to export, with those specs and examples it should be pretty easy 
to implement.

[android-developers] Re: Eclipse/ADT not rebuilding correctly

2011-05-10 Thread snpe

It's possible that ApkBuilder locks *.apk file when a exception
occurs. ApKBuilder work a lot operation with apk file without closing
them when a exception happen.
The problem disappear when user refresh (unlock) the file or restart
OS.
Restarting is obligate on Windows because Linux/Mac don't lock file.

To test it on Windows, you can try remove *apk file using OS command
(or using Eclipse Navigator view) when a problem occurs.
If the file is locked you won't remove it without restarting Eclipse.
On Linux refreshing helps and removing the file will work.

Unfortunately, I can't reproduce the issue on Linux. Maybe, I will be
able do it, if somebody attach a project example and some test case.

Peco

 I looked in the above two tables since a lot of web queries showed the

 On probing the source of Gingerbread, I found out that the values are being
 stored in the com.android.providers.telephony/telephony.db

 Is this a change in the Gingerbread or am I getting my research wrong?

[android-developers] NFC testing rig?

2011-05-10 Thread Marcin Orlowski

Hi,

We're going to fight with NFC for the next project and since I saw a few
people with much more knowledge on the subject on that list I'd like to ask
if anyone got any thoughts to share on building testing environment for such
projects. I mostly need Android mobile and some standalone NFC device to
test it all with. I did quick research yesterday yet I failed to find
anything but Nexus S (I do not look for non-Android devices for this phase
of the project, not sure if any exists anyway - I found some announcements
but seem these did not turned into products yet). As for standalone device
some companies seem to offer what I need too, i.e.
http://www.insidesecure.com/eng/Products/NFC-Products so there's a hope :)

Anyway, if anyone who spent some time on the subject and is willing to share
the lesson, I am all ears. Thanks in advance :)

Marcin Orlowski

[android-developers] In a Native C program, how to call java API: ActivityManager::getMemoryInfo()

2011-05-10 Thread linlone9

In Java program, we can use following codes to get the system memory info:
===
ActivityManager activityManager = (ActivityManager)
getSystemService(ACTIVITY_SERVICE);
MemoryInfo info = new MemoryInfo();
activityManager.*getMemoryInfo*(info);
===

But now, we need to get system memory info from Native C program. So, I have
to implement following codes to new MemoryInfo object:
===
jclass cls = env-FindClass(android/app/ActivityManager$MemoryInfo);
jmethodID ctor = env-GetMethodID(cls, init, ()V);
jobject *objMemoryInfo* = env-NewObject(cls, ctor);
===

Up to now, we have got the MemoryInfo's object objMemoryInfo.


Then I need to input *objMemoryInfo* to *parcelMemoryInfo*, but don't
how to convert from Parcelable to Parcel:
===
int GET_MEMORY_INFO_TRANSACTION = IBinder::FIRST_CALL_TRANSACTION+75;

spIServiceManager sm = defaultServiceManager();
spIBinder am = sm-getService(String16(activity));
Parcel *parcelMemoryInfo* = *objMemoryInfo*; * //HERE: how to convert
from Parcelable to Parcel
*Parcel reply;
status_t ret = am-transact(GET_MEMORY_INFO_TRANSACTION, *
parcelMemoryInfo*, reply);
===

The progressbar is just that - a bar. You have to code the other view

[android-developers] Characters appear out of the screen in the TextView!

2011-05-10 Thread omar

Hey, I've been trying to fix this problem for a long time, The problem
is that some characters in the text are out of the screen, here is a
screenshot of what I mean:
http://i.imgur.com/fDqa6.png

xml:

?xml version=1.0 encoding=utf-8?

  RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:background=@drawable/list
  android:orientation=vertical
  android:padding=15dip
  android:layout_width=fill_parent
  android:id=@+id/relativeLayout1
  android:layout_height=fill_parent

  TextView
android:textSize=20sp
android:layout_width=wrap_content
android:layout_height=wrap_content
android:textColor=#000
android:id=@+id/Munawwat_Text_TextView_text
android:layout_alignParentRight=true
/

/RelativeLayout


Can anyone suggest a way/workaround to fix this problem?

A workaround for this is to put it into an EditText. If I put the text
into the EditText, the EditText gets horizontally scrollable
(scrollable for ~3px) which is good so you can see the characters that
are out of the screen but i dont want to let the users mess with the
text.. So:
1. Is it possible to not allow the users to edit in the EditText and
in the same time let the EditText get scrollable?
2. Is there any other view that i can put the TextView into it, so it
can get scrollable a bit so I can see the characters? (limit the
scroll of the view)
3. Is there a way to limit the number of characters in each line in
the TextView?

I know I asked a lot though this is one of the last problem I have so
I would really appreciate any comment/suggestion!

Re: [android-developers] Re: Local variable type mismatch

Do you have any machine-generated .class files, or any supplied in

If you do, that'd be the first place to check.

Re: [android-developers] NFC testing rig?

2011-05-10 Thread Xiaoliang Ding

Nokia C7 support NFC so far.

2011/5/10 Marcin Orlowski webnet.andr...@gmail.com

 Hi,

 We're going to fight with NFC for the next project and since I saw a few
 people with much more knowledge on the subject on that list I'd like to ask
 if anyone got any thoughts to share on building testing environment for such
 projects. I mostly need Android mobile and some standalone NFC device to
 test it all with. I did quick research yesterday yet I failed to find
 anything but Nexus S (I do not look for non-Android devices for this phase
 of the project, not sure if any exists anyway - I found some announcements
 but seem these did not turned into products yet). As for standalone device
 some companies seem to offer what I need too, i.e.
 http://www.insidesecure.com/eng/Products/NFC-Products so there's a hope :)

 Anyway, if anyone who spent some time on the subject and is willing to
 share the lesson, I am all ears. Thanks in advance :)

 Marcin Orlowski

Re: [android-developers] Does android supports modal dialog box ?

Although the dialogs are *almost* modal in Android, they are
fundamentally (or practically) asynchronous.

Search for modal dialogs and android in google and you will see a lot
of write up from this news group.

So you have to reorient your programming where you can alert and wait
the main thread. This is just not possible (as far as I know).

If you are using alerts for debugging you may want to use toast or Log.d.

Bottom line you cannot stop the main thread while a dialog is being
acted upon and finished.

Re: [android-developers] Re: Async Task or Spawn a Thread?

I would say

1. Understand first how handler/looper/threrading works in android
2. Then you will realize that AsyncTask is just one pattern on top of
the above basics
3. Try to use AsyncTask if it can work for your problem as it
simplifies the mechanics of threading/handlers. if not then go for the
guts using handlers/threads

Coming to thread pools the latest documentation seem to suggest that
after honeycomb the AsyncTask may roll back to a single thread
implementation and have the programmer deal with multiple threads
explicitly.

 I'm OK with having people who aren't very experienced with threads create a

 problem -- or worse, living with it. And it's not really that high an
 overhead, either in code complexity or time and memory. It's not like it's
 creating a new thread each time.
 Just to be clear: Handler/Looper doesn't give you threads. I've seen people
 get very confused on this point! It does make using threads, well, not
 simpler, but safer. If you're interested in passing off work to another
 thread, then it's better to use Handler/Looper than to try to handle the
 synchronization of passing off the work item yourself.
 Still, since you have to create that work item to pass it off, generally
 speaking, you might as well make it an AsynchTask, and get thread pooling,
 clean interface to the UI thread, and convenient progress bar handling for
 free. The only time I can think of to prefer Handler/Looper is when the
 thread pooling behind AsynchTask doesn't fit your needs -- and if it
 doesn't, you may want to consider your needs, as having lots of threads
 takes lots of memory (for the stacks).

 And there is one other tool in Android that is still useful for
 Threads, when barebones Java Threads are too much of a bother to
 manage: Looper/Handler. This was the standard Android threading
 'workhorse' before AsyncTask (or its unoficcial predecessor UserTask)
 became so popular.

 It there any way to unit test the new drag n drop feature? Can anybody

[android-developers] Problem working with SOAP (lib kSOAP2)

2011-05-10 Thread Gorka

Hi,

I am trying to access to a web service using SOAP using the ksoap2
libraries. The thing is that I can make some examples work, but I
cannot access the service I am interested in.

There is the service: http://apli.bizkaia.net/APPS/DANOK/TQWS/TQ.ASMX
And that is the method I want to consult:
http://apli.bizkaia.net/APPS/DANOK/TQWS/TQ.ASMX?op=GetPasoParada

Sort description

POST /APPS/DANOK/TQWS/TQ.ASMX HTTP/1.1
Host: apli.bizkaia.net
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: http://tempuri.org/LANTIK_TQWS/TQ/GetPasoParada;

?xml version=1.0 encoding=utf-8?
soap:Envelope xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;
xmlns:xsd=http://www.w3.org/2001/XMLSchema; xmlns:soap=http://
schemas.xmlsoap.org/soap/envelope/
  soap:Body
GetPasoParada xmlns=http://tempuri.org/LANTIK_TQWS/TQ;
  strLineastring/strLinea
  strParadastring/strParada
/GetPasoParada
  /soap:Body
/soap:Envelope

That is my code:

private static final String SOAP_ACTION = http://tempuri.org/
LANTIK_TQWS/TQ/GetPasoParada;
private static final String METHOD_NAME = GetPasoParada;
private static final String NAMESPACE = http://tempuri.org/
LANTIK_TQWS/TQ/;
private static final String URL = http://apli.bizkaia.net/APPS/DANOK/
TQWS/TQ.ASMX;

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); //set up
request
request.addProperty(strLinea, *); //variable name, value. I got
the variable name, from the wsdl file!
request.addProperty(strParada, 48036029); //variable name, value.
I got the variable name, from the wsdl file!
SoapSerializationEnvelope envelope = new
SoapSerializationEnvelope(SoapEnvelope.VER11); //put all required data
into a soap envelope
envelope.setOutputSoapObject(request);  //prepare request
envelope.dotNet = true;
HttpTransportSE httpTransport = new HttpTransportSE(URL);

try {
httpTransport.call(SOAP_ACTION, envelope);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} //send request

SoapObject result=(SoapObject)envelope.bodyIn;
Log.d(TAG, Result:  + result.toString());

The thing is that I don´t get any response. Well, actually I do, but
it is an error message:
GetPasoParadaResponse{GetPasoParadaResult=Object reference not set to
an instance of an object.;}

It would be great if someone knows how can I solve my problem.

Thanks a lot, Gorka

once your phone is connected run the adb devices command.

Try txt to number that appears next to your phone. For example here I

This group is for developing Android apps with the Android SDK. I don't see
anything in your post that is specifically Android related. You would have
much more luck, I think, in a group or forum dedicated to SOAP.

[android-developers] Activity is destroyed than instantly created when pushing the sleep/lock-screen button

2011-05-10 Thread Jump

Hello

When I run my game app and then push the sleep/lock-screen button my 
activity is destroyed (onDestroy is called) and then directly after, 
onCreate is called.

However, if I first put my app in the background then push 
the sleep/lock-screen button the activity is not destroyed.

Can anyone explain this behavior and/or how I can get around it (keeping the 
app alive). Angry Birds actually keeps the music running when the lock 
screen is on, maybe there's some trick with that you can use?

I do not want to handle state.

Thx.

thank you Smiley but i've already tried that ,the problem is that iam
working on both :emulator and real device ; the first is acting like a
server and the second where the application is (client) so the real
device appear whith a certain ID  I5500f1aab23d not a port number
like emulator emulator-5554 witch 5554 is the port number .
so how can i target the real device from the emulator ?

Re: [android-developers] Re: Long process before a dialog is opened

I have thought about this a bit further.

You should be able to do this with some work.

If I am not mistaken what you are wanting to do is a special case of
something like a Progress Dialog except it is custom and the user
wants to dismiss it explicitly. Also you must not wait for the
onPostExecute.

My high level thougths are:

1. Create a dialog as you normally do in onCreateDialog() and return that dialog
2. Keep a pointer to the dialog so that you can alter the view in that
dialog some manner
3. Kick off your asynctask
4. Update progress on your dialog with a visual cue
5. OnPostExecute enable a button on the dialog to do the desired
action by the user

I think this will work...(if it suits your intent)

Re: [android-developers] Re: Long process before a dialog is opened

 Or (if I understand your context right) better yet, show a progress
dialog when the menu is clicked and when the progress dialog finishes
show your special dialog thereby fulfilling both requirements of
visibility and long running process.

[android-developers] Why is my progress bar not visible?

2011-05-10 Thread Ralph Bergmann

Hi,


I have an indeterminate progress bar in the window's title bar. I have
also requested it with:

@Override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);

// ...
}

But why it is not visible when I call
setProgressBarIndeterminateVisibility(true); ?

In another activity it works.


Ralph

Re: [android-developers] Re: ListView - is it possible to limit the fling speed?

2011-05-10 Thread Omar Adobati

OK, it was my bad.
I have found the reason, well the stupid reason.
Probably, with testing purpose, I did put a notifyDataChange in the
getView Adapter method.
This was preventing the list to stop scrolling when touched...

Sorry for being wasting your time!

 That's probably not going to work reliably, even if you managed it.
 The latest NDK allows you to create an activity entirely in native

  How can I get the absolute path to an asset file or resource file, and
  can it be opened by the 'c' code?

 The easiest way is to copy the file on the file system (or SD card),
 in your app's onCreate() the first time you run it, and pass the
 absolute path to your native code from there.

[android-developers] menu item disabled, but clickable

2011-05-10 Thread Zanarotti Michele

I ever thought that a disabled menu item (setEnabled(false)) should appear 
grayed out (and that works) and
furthermore it should not be active as i click on it (it should not close 
the menu).

How can avoid the closing of the menu ? shouldn't this be the default 
behavior of a disabled menu item ?

[android-developers] Intent to launch Google Latitude

2011-05-10 Thread cg-dev

Hi all,

I'm trying to launch Google Latitude using Intent.

I'm using an URI found on the net :

latitude://latitude/friends/location/exam...@gmail.com

And this code :

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
intent.addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);
startActivity(intent);

It's seems ok.

1°) But I would like to know if there is an official documentation
about this URI syntax.
I'll check in GoogleAPI doc, but did not find anything specific to
Android.

2°) Do you know a way to launch a check in in latitude application ?

Thank you.

Re: [android-developers] putExtra not working for a pending intent

There is enough material on this forum if you search with 'pending
intent' especially around its uniqueness criteria.

At a high level, pending intents are references to already stored
intents. A pending intent uses the input intent as a key to locate
previously established pending intent for this intent. The key to
locate this does not include the extras. All other parts of an
intent participate in this uniqueness.

So even if you set extras different on 10 different intents
(everyother part of an intent being same) will result in a single
pendingintent.

The flag that was suggested will retreive that previous intent and
replaces the new extras on the old one.

You can also use something called a requestid to make the intents
unique. But it is suggested in the docs that you don't want to create
a lot of pendign intents if you have other ways of solving it.

Hope this brings a bit more background to pending intent

But I can't figure out how to change the standard blue line that is a
little bit thicker when the tab is selected to a different colour.
Any ideas of how I could achieve this?

André

[android-developers] Re: Register and UnRegister Broadcast Receiver

2011-05-10 Thread Igor Prilepov

1. Register broadcast receiver in onResume() without any additional 200ms 
and add some logic inside receiver to ignore intents for the first 200ms 
after startup. 
or
2. If you still want to do such weird things (i.e. to register BR in another 
task?!) then you need to inform this task when onPause is called to prvent 
new BR to be created. Because this is exactly what has happened: your 200ms 
task creates a broadcast receiver after the app has received and processed 
onPause(). 
IMHO the whole idea of creating BR in another task contradicts the Android 
design and should be avoided.

[android-developers] Re: hash functions

2011-05-10 Thread DanH

For your purposes any standard hash algorithm that produces the
desired number of bits should be fine.  The weakness of hash
algorithms has to do mostly with the ability to counterfeit data
that produces a given hash value -- this is an important consideration
when the hash is being used in a digital signature algorithm, but
not important if you're just hashing, say, an alpha password to create
a key.

[android-developers] Status bar area not covered when activity is resumed

2011-05-10 Thread groob

Hello!

I'm experiencing very nasty bug trying to implement Admob in my
application.
I thought the problem is in my code, but after some investigation I
found it present also in Android-Banner-Essentials example (available
for download here: 
http://code.google.com/mobile/ads/docs/android/fundamentals.html)
I wonder if anyone ever met this problem or maybe knows how to deal
with it.

Basically, when application has both status and title bar disabled, it
should use full screen.
Banner Essentials example displays nothing but Admob banner on the
very top of area available.
I downloaded the example, changed only two things:
- added my publisher ID to compile properly and receive any ads ;)
- added one param to activity's manifest to disable title and status
bar:
android:theme=@android:style/Theme.NoTitleBar.Fullscreen

Compiled binary, no matter what device is it launched on (tried Nexus
One, G1, Desire, different Android versions), is affected with the
same issue:
- when ad banner is displayed press Home,
- once taken back to home screen press and hold Home to see recently
launched apps,
- select back Banner Essentials app.
My tests reveal that with 50% reproduction chance Admob banner doesn't
go back to its position -the very top of the screen.
To show better what I mean I prepared three screenshots:
http://goo.gl/u9DTl

Important notices:
- when app is resumed normally, banner is displayed just below status
bar, and slides up until is aligned to the top screen border,
- when error appears the banner doesn't move at all,
- I couldn't reproduce the issue with any other interrupt (pressing
Back, Power Button),
- I think it may be somehow connected to gaining/losing foucs (see
screenshots).

My app is bit more complex than Banner Essentials so I started with
searching the issue in my code, with no luck, thus tried to simplify
the situation as much as possible and here are the results.

Does anyone know what may be causing the problem? Maybe some
additional flags or properties has to be set to handle this behaviour?

Any advice will be appreciated.

Regards.

[android-developers] Re: Convert from Polyline to ArrayListLocation

2011-05-10 Thread Igor Prilepov

It is unrealistic because people collect points and then show them as 
polyline, polygon or just dots not the other way around.
It is unrealistic because Google MapActivity on Android is different from 
the full scale Google Map API.
It is trivial because any Polyline (or Polygon) should be stored as some set 
of points and therefore all you need to do is to open a documentation to 
find out how exactly to do this. For example, if you open 
http://code.google.com/apis/maps/documentation/javascript/3.3/reference.html#Polyline
 you 
will find getPath()method to get 
MVCArrayhttp://code.google.com/apis/maps/documentation/javascript/3.3/reference.html#MVCArray
 
LatLnghttp://code.google.com/apis/maps/documentation/javascript/3.3/reference.html#LatLng
.

[android-developers] directly loading dynamically created classes (in dex format)

Hi friends,

I have an application which dynamically creates classes at runtime (in
the dex format). Is it possible to load these dex bytes directly
without saving them to a dex file, and then zipping it (many such
classes are created). An equivalent of
ClassLoader.createClass(className, classDexBytes) is what I'd like.
I.e. a DexClassLoader that doesn't have to reference a physical file,
but can be passed byte arrays instead.

Thank you very much for your help,
Tomasz

[android-developers] Re: hash functions

2011-05-10 Thread Bob Kerns

The fundamental problem with starting with a human-managed password is that 
there is not a lot of entropy -- the possible values are not distributed 
over a huge range, compared to what an attacker could try with 
trial-and-error.

So just doing SHA1 or SHA256 for that matter, is not sufficient for a strong 
key generation algorithm.

The first thing you need to address are dictionary attacks, where the 
attacker can pre-compute a large dictionary of keys from likely passwords. 
Here, you can inject randomness into the process. What you do is to start 
with a large random number, termed a 'salt'. This is not a secret -- you'll 
save it away in cleartext somehow, and then combine it with the user's 
password. While the attacker could afford to build a dictionary of keys 
based on passwords, a dictionary of possible salt values + passwords would 
be vastly larger.

The other thing you need to do is to protect against trial-and-error 
attacks. To do this, what you do is make it expensive enough to compute the 
key that an attacker simply couldn't try enough to get anywhere. The usual 
way of doing this is to iterate some expensive function -- such as SHA1. 
More precisely, you iterate this:

hash = f(hash)

where f is some function that is expensive, and does not collapse the space 
of possible values into some smaller set. One way to accomplish this would 
be:
f(hash) = hash xor sha1(hash).

I went with SHA1 above, because I want to tie this to PBKDF2, which Nikolay 
referenced.

What I outline above is roughly what PBKDF2 does for you. You can read the 
full details in rfc2898 http://tools.ietf.org/html/rfc2898, and I 
encourage you to do so. I did skip over a lot of detail to focus on the 
motivation and approach.

So there are basically two parameters -- the salt (selected randomly) and 
the iteration count (selected to make it expensive but not too expensive). 
 iOS4 uses I believe something like 1 iterations. Blackberry used 1, and 
was seriously pwned as a result.

Together, these compensate for the narrow range of human-generated 
passwords.

/* --this doesn't work in current version of Dalvik--
if (data != null) {
System.out.println(--- Found class  + name

if (packageObj == null) {
definePackage(packageName, null, null,

}
}
}

return defineClass(name, data, 0, data.length);
}
*/

Does anyone know when they are planning on implementing this?

[android-developers] HttpsURLConnection's getResponseCode() returns -1

2011-05-10 Thread John Gaby

I am trying to use HttpsURLConnection to connect to a secure site, and
it is failing and getResponseCode() is returning -1.  The following is
the code that I am using.  Note that this very same code works in
other cases.  Can anyone give me a clue as to why I might get the -1,
and how I can get more information about what is going wrong.  Also
note, that if I take the URL that I am trying to connect to in this
call and paste it into a browser, I get the correct response, so I am
pretty sure that the URL itself is correct.  In this particular call,
m_data is null, so it is performing a GET and no data is written.

Thanks

HttpsURLConnection connection = null;

try
{
URL url = new URL(arg0[0]);
connection = (HttpsURLConnection) url.openConnection();

// Allow Inputs  Outputs if there is data to send
connection.setDoInput(true);
connection.setDoOutput(m_data != null);
connection.setUseCaches(false);

// Enable GET or POST depending on whether there is data to
send
connection.setRequestMethod((m_data == null) ? GET :
POST);

connection.setRequestProperty(Connection, Keep-Alive);
connection.setRequestProperty(Content-Type, application/
octet-stream);

if (m_data != null)
{
DataOutputStream outputStream = null;

connection.setFixedLengthStreamingMode(m_data.length);

outputStream = new
DataOutputStream( connection.getOutputStream() );
outputStream.write(m_data);

outputStream.flush();

[android-developers] Error while Compile Android Gingerbread 2.3.3

2011-05-10 Thread spurwa

When I compile the source android Gingerbread 2.3.3 is that I receive
an error message like this:
build / core / binary.mk: 25: *** external / stlport: Invalid
LOCAL_NDK_VERSION '4 'Choices acres. Stop.)

For information I have to download and Compile on 64bit Linux Ubuntu
10.04 Lucid in accordance with the instructions.

Any ideas what's the solution?

Thank you
SGP

 Nothing new should have been using MD5 for a looong time, and people need to
 know to stay away from it.
 Fake SSL certs that exploit this have been produced. It's not just a
 theoretical concern.

I know :) But as with most things, one shouldn't avoid it just because
one heard somewhere that it's 'weaker'. At least a bit of research
is needed, that's what my comment was meant to say. And the
MessageDigest class reference was not exactly relevant.

[android-developers] Serial Number

2011-05-10 Thread New Developer

When I start or connect my Xoom  I get  in Console

[2011-05-10 21:15:29 - eeds] Automatic Target Mode: Unable to detect device 
compatibility. Please select a target device.
[2011-05-10 21:16:20 - eeds] Uploading new.apk onto device '0288...b397'
[2011-05-10 21:16:22 - eeds] Installing new.apk...

I assumed 0288...b397  is the serial number yet when I execute

SERIAL_NUMBER  = Secure.getString(getBaseContext().getContentResolver() ,  
Secure.ANDROID_ID);
Log.i(Activity , Serial Number =   ' + SERIAL_NUMBER   + ' 
 );
I get the following in LogCat

05-10 21:16:26.400: INFO/Activity(1354): Serial Number =   '7299...b099'  

Not the same Number.
So which is the correct serial Number and how do I find the serial number on 
the Xoom itself ??

Thanks in advance

will be more

https://market.android.com/details?id=com.ambrosoft.searchlib

You can preview all the books before buying at a discount.
After you buy a book, you will be able to download EPUB for your
archival purposes
eCarrel is specialized for non-fiction, scientific or technical text.
Superb search engine and social networking built-in.

This is only a beta so please be patient -- bugs are quite likely,
as you can expect.
I'd love to get your positive feedback and ideas for improvement.

[android-developers] Re: hash functions

2011-05-10 Thread DanH

Of course, hashing a password, per se, doesn't really make it any
stronger.  And doing things like using a salt don't do much if the
concern is simple trial-and-error cracking of a single encrypted
message (unless you're relying on security by obscurity).  Salting
does help prevent known plaintext attacks and signature spoofing, but
those are not likely to be problems in low-volume messaging.
Iterating on an expensive hash can help discourage the trial-and-error
cracking attack, but it can add considerable overhead to the normal
path, and simply increasing the length of a weak password would be far
more effective.

On May 10, 5:34 pm, Bob Kerns r...@acm.org wrote:
 The fundamental problem with starting with a human-managed password is that
 there is not a lot of entropy -- the possible values are not distributed
 over a huge range, compared to what an attacker could try with
 trial-and-error.

 So just doing SHA1 or SHA256 for that matter, is not sufficient for a strong
 key generation algorithm.

 The first thing you need to address are dictionary attacks, where the
 attacker can pre-compute a large dictionary of keys from likely passwords.
 Here, you can inject randomness into the process. What you do is to start
 with a large random number, termed a 'salt'. This is not a secret -- you'll
 save it away in cleartext somehow, and then combine it with the user's
 password. While the attacker could afford to build a dictionary of keys
 based on passwords, a dictionary of possible salt values + passwords would
 be vastly larger.

 The other thing you need to do is to protect against trial-and-error
 attacks. To do this, what you do is make it expensive enough to compute the
 key that an attacker simply couldn't try enough to get anywhere. The usual
 way of doing this is to iterate some expensive function -- such as SHA1.
 More precisely, you iterate this:

 hash = f(hash)

 where f is some function that is expensive, and does not collapse the space
 of possible values into some smaller set. One way to accomplish this would
 be:
 f(hash) = hash xor sha1(hash).

 I went with SHA1 above, because I want to tie this to PBKDF2, which Nikolay
 referenced.

 What I outline above is roughly what PBKDF2 does for you. You can read the
 full details in rfc2898 http://tools.ietf.org/html/rfc2898, and I
 encourage you to do so. I did skip over a lot of detail to focus on the
 motivation and approach.

 So there are basically two parameters -- the salt (selected randomly) and
 the iteration count (selected to make it expensive but not too expensive).
  iOS4 uses I believe something like 1 iterations. Blackberry used 1, and
 was seriously pwned as a result.

 Together, these compensate for the narrow range of human-generated
 passwords.

Do you mean you implemented this yourself? Not that it's too hard to do, but
Android has the Bouncy Castle JCE provider, so all you have to do is usually:

SecretKeyFactory factory = SecretKeyFactory.getInstance(KEYGEN_ALGORITHM)
KeySpec keySpec = new PBEKeySpec(password, salt, numInterations,  keyLen);
SecretKey key = factory.generateSecret(keySpec);

where KEYGEN_ALGORITHM is a supported PBE algorithm.
