Re: [android-developers] Re: Problem with GridView

2011-03-14 Thread leela kissnaa

Hi,
i thought starting new Activity will take more time than what i am doing..(I
may wrong)

to show images what is the action tag to intent which i going to fire..
can you send me some sample code links which can help me to show images more
effectively (Multi touch zoom included..)

 Rather than removing everything and changing the layout params to make it
 full screen, why not just create a second activity that is designed to
 display the fullscreen image?

 Then when the user clicks the image you don't have to remove any images
 from the layout... you can just fire off an intent to view the image.

[android-developers] Re: Multi touch zoom in or out

2011-03-14 Thread varun

ImageView supports multi touch. In-fact every view supports multi
touch it maybe the problem with harware.

any how what you need to do is you need to implement on touch
listener. there  you have to read actions ACTION_POINTER_UP and
ACTION_POINTER_DOWN for multi touch. read something about these and
you will figure it out.

[android-developers] Unhandled algorithm md5 requested

2011-03-14 Thread marten

Hello,

I'm writing a CardDAV implementation for Android and came across some
problem when trying to connect to the OSX/Darwin CardDAV server.
The default setup for this server is to advertise BASIC and DIGEST
authentication. The default algorithm for DIGEST authentication is set
to md5.
Without changing the defaults I can not login to the server. I always
get the following error in the logs:

E/estTargetAuthentication( 2749): Authentication error: Unhandled
algorithm md5 requested

If I change md5 to MD5 in the server's configuration I can login
to the server.
In my opinion Android is right and it should be MD5 instead of
md5. Nevertheless, is there any way to make Android's HTTP
implementation more tolerant? Can I register md5 as an
implementation of MD5 somehow?
I don't want to ask all OS X users to change the defaults ...
especially since OS X users are used to that it just works ;-) .

cheers

Marten

well, i call the RingtonePicker in my preferences in xml

more then the above stack i dont have. can it be that at the time it
happens the system had a general overload and my app was just used in
the wrong moment?

[android-developers] Re: Background Service

2011-03-14 Thread Jonathan Foley

What you are after is the WebView method addJavaScriptInterface:

http://developer.android.com/reference/android/webkit/WebView.html#addJavascriptInterface(java.lang.Object,
java.lang.String)

As the name implies, this creates an interface between Javascript in
the webpage and your Java code. You''ll need to use that to have your
JS return values to your Java object.

If the computations you refer to are long-running then do them in an
AsyncTask in the Activity hosting the WebView. You'll inject the
values back into the loaded webpage using JS. You can pass javascript
code to loadUrl() and it will execute. For for instance you can
generate from JS code that modified the elements you want after the
computation completed.

Hi TreKing,

I already have my own webview application that will load a custom
webpage. I need to get user inputs from the data field in the webpage
to do some computation and insert back the result into the webpage.

I am thinking of writing a background service and couple it with this
application. But I am not sure how to do the interaction with the
webpage. Getting and inserting into the data field.

Is this possible to be done through a background service?

Perumal

You don't detect another application. You start your service from your
Activity.

Should I package the application and service together?

A Service has to be packaged with *some* application - particularly the one
that is going to be starting it. So yeah.
