[android-developers] need help on https (code for http included)

2009-09-04 Thread DaRolla 

hello,

I need some help on https connections.

I am using this code to connect to my http servlet in order to stream
objects and recieve object streams:

.
.
.
import lgpl.haustein.Base64Encoder;
import java.net.URL;
import java.net.URLConnection;
.
.
.
private String login;
private String password;
.
.
.
URL url = new URL(ANDROID_HTTP_SERVER);
URLConnection connection = url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
String encoding = Base64Encoder.encode(login + : + password);
connection.setRequestProperty(Authorization, Basic  + encoding);
.
.
.

The lgpl.haustein.Base64Encoder I have found here:
http://www.winterwell.com/software/jtwitter.php

I really do not know how to work with https. especially the licence is
not valid, so I need to ignore it automatically.

Thanks for your help.

Greetings,
Marco

PS: I am working with SDK 1.1 R1, so please don't send me SDK 1.5
code...

[android-developers] problems removing childs from view

2009-04-29 Thread DaRolla 

hello,

I have some problems removing views.

Inside my xml I have a LinearLayout with a ScrollView with a
TableLayout.

Into this I am adding (using Java) childs, which are LinearLayouts (no
TableRows).

This works fine.

Now I want to remove some childs, which are LinearLayouts.

linearlayout.setVisibility(View.GONE) works finde but doesnt remove
the Object itself.

tablelayout.removeView(linearlayout) works only under strange
circumstances: removing the last element of my list works fine.
removing some element in the middle throws this exception:

Uncaught handler: thread main exiting due to 
uncaught exception

linearlayout.removeAllViews() I tried in order to clear all childs of
my linearlayout (which are some buttons and textviews in fact), but
this doesnt change anything.

Any idea what I am doing wrong?

[android-developers] changing language on demand?

2009-04-23 Thread DaRolla 

hello,

I need to change the language of a running apk on demand.

So the texts are set in xml to @strings/name

And there are different strings.xml inside values-de values-en values-
tr and so on.

Is there a way to tell android to update the layout in order to change
the strings automatically?

Or do I have to replace all of them by hand using findById().setText
(R.strings.name) ?

[android-developers] Castor unmarshalling with Android's SAX DOM implementation throws: The 'namespace-prefix' feature is not supported while the 'namespaces' feature is enabled

2009-04-21 Thread DaRolla 

hello,

in order to generate Java classes from XML schema I use Castor.

These classes have unmarshalling methods for loading and parsing XML
files.

In JDK I'd use Xerces as SAX DOM implementation.

As I understood Android it comes with its own implementation.

Trying to unmarshal the XML file in Android this Exception is thrown:

org.exolab.castor.xml.MarshalException: The 'namespace-prefix' feature
is not supported while the 'namespaces' feature is enabled.

Things are working fine in JDK.

So I think its thing of Androids SAX DOM implementation.

Can you please help me how to get rid of this error?

Here's a part of the XSD:

?xml version=1.0 encoding=UTF-8?
xs:schema xmlns:xs=http://www.w3.org/2001/XMLSchema;
elementFormDefault=qualified attributeFormDefault=unqualified
xs:element name=sport...

And here's part of the XML:

?xml version=1.0 encoding=UTF-8?
sports xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;
xsi:noNamespaceSchemaLocation=sports.xsd
sport id=soccer...

Thanks for help.

[android-developers] java.lang.StackOverflowError when deserializing

2009-04-21 Thread DaRolla 

hi,

I've got a strange problem here doing object de/serialization.

In Java (JDK 1.6) I serialize some objects.

In Android (SDK 1.1) I deserialize them.

This work quite nice in general.


In order to work with a server object (that uses Castor un/
marshalling) I do it like I always do. Same routines. Well, this time
the file is only 172kb (my routines works pretty well with 2,4mb
files) but the interlacing is quite deep. So it all starts with a
class containing 2 ArrayLists. I tried de/serializing just
ArrayListString and this works very well. But the XML file (which is
unmarshalled with Castor and serialized in JDK) has 7000 lines. So I
get this StackOverflowError.

[android-developers] Is there a Castor for Android?

2009-04-17 Thread DaRolla 

Hello,

I need Castor for Android. Using the castor-1.2-xml.jar won't work at
all. The exception is: java.lang.VerifyError:
org.exolab.castor.xml.Introspector

So I tried to copy the Castor sources to my Android project in order
to let Eclipse decide which part isn't compatible.

Well, it's just one class: org.exolab.castor.dsml.jndi.JNDIProducer

This class imports javax.naming.*, and thats forbidden inside Android.


So, I think there might be other users that got the same problem as me
and maybe solved it?

[android-developers] global object? (singleton, intends, db)

in order to communicate with the server I need a huge global object

all my activities (about 10) need that huge global object.

wich options do I have?

I am thinking about passing the object using intends and about the
possibility to make the object a singleton.

using the db will be much too slow.

[android-developers] I need to use jbossall-client.jar

2009-03-17 Thread DaRolla 

hello,

I need to use some jars inside android. well, most of them work. It
seems that the standard java compiled jars are decompiled and compiled
into dalvik format (for example Log4J.jar).

The only jar that makes troubles is jbossall-client.jar.

Eclipse console says:

Attempt to include a core VM class in something other than a core
library.
It is likely that you have attempted to include the core library from
a desktop
virtual machine into an application, which will most assuredly not
work. If
you really intend to build a core library -- which is only appropriate
as
part of creating a full virtual machine binary, as opposed to
compiling an
application -- then use the --core-library option to suppress this
error
message. If you go ahead and use --core-library but are in fact
building
an application, then please be aware that your build will still fail
at some
point; you will simply be denied the pleasure of reading this helpful
error
message.

So I tried to remove the javax package from the jar.

Now Eclipse console says:

Conversion to Dalvik format failed: Unable to execute dex: null

:(

Who can help me on this?

My solution:
1) build a core library with consisting out of
