[android-beginners] Re: Adding Undo feature in FingerPaint app bundled with APIdemos.
:) Thanks James for your reply. I was skeptical about the said approach because it will consume some memory and we all know how precious that is on the device. I was checking to make sure that I am not missing anything available in the framework, here. If the framework could let us have hooks for establishing savepoints and then reverting back to them, I'd rather used that approach.

[android-beginners] Project Idea....Not sure if its possible!
Hi guys thiss is my first time posting and I really have no clue of the capabilties of Android etc so pease bear with me. Ok basically what I would like to do is create an app using gps, which tracks the direction and speed the user is moving. now the next part is the part im not sure if it is possible. I need the app to either track other users movements or recieve info from other users about their movements(directions and speed). The other users would be using the same app but on seperate devices. The users would be within no more than 30 meters apart. Does anybody know if this would be possible, and how difficult it would be if possible?

[android-beginners] Displaying a single oversized image + using zoom features
I'm writing an application that involves basically printing a single image to the user, in full screen mode. The images that will be printed are very large, much larger than the screen resolution of most devices. I don't want to scale or resize this image, instead I'd like the user to be able to swipe his/her finger around to see the rest of the image, and to add some zoom options too. My question, is this possible with ImageView? Everytime I try it it'll just try and shove as much of the image it can onto the screen, which is not what I want. Any help would be great, thanks.

[android-beginners] Re: Project Idea....Not sure if its possible!
Yes this is possible. You will need to create web service also where user movement is stored. The book I was reading Professional Android Application Development covers how to make the speed application. The application will need to probe a webservice now and then to attain the locations of other users and also submit it's own location and speed data. So basicall you need: 1. Local Android Application 2. Reliable internet connection on running devices (GPRS is fine as long as it is reliable) 3. A central database somewhere that holds all location and speed data...(Maybe a Java Applet).

I have tried it with reading bmp and jpeg image from pasting in
res/drawable folder and it works fine with 1D barcode. Its not working
with 2D and i dont know how to do it though multiformat i guess means
it shud support 2D as well. Well this will solve ur problem. I also
tried to read it with a sdcard image coz after all it has to fetch
from the image taken by camera. but i dont have a camera and unable to
push image in gallery after lots of tries so it still undone.
Share anything else you cum to know abt barcode decoding task.

Hello All,
I am writing an application to scan a bar code.
As a small module of it I am trying to decode the bar code form the
image file stored as resource. (R.raw.bc02) where bc02.jpg is my bar
code image file.
I am usinghttp://code.google.com/p/zxing/wiki/DeveloperNotestowrite
a program for decoding.
I am stuck up at following step: i.e. reading the image as
bufferedImage
BufferedImage myImage = ...;
MonochromeBitmapSource source = new
BufferedImageMonochromeBitmapSource
(myImage);
I have written following code to read the image which works fine
InputStream is= this.getApplicationContext().getResources
().openRawResource(R.raw.bc02);
The run time object is of class android.content.res.AssetManager
$AssetInputStream
Can any help me in reading the file and decoding? Please let me know
if I am doing correct or not.
Thank you,
Abhishek

[android-beginners] Re: Project Idea....Not sure if its possible!
Sorry Servlet not Applet :p On Oct 10, 10:17 am, jax jackma...@gmail.com wrote: Yes this is possible. You will need to create web service also where user movement is stored. The book I was reading Professional Android Application Development covers how to make the speed application. The application will need to probe a webservice now and then to attain the locations of other users and also submit it's own location and speed data. So basicall you need: 1. Local Android Application 2. Reliable internet connection on running devices (GPRS is fine as long as it is reliable) 3. A central database somewhere that holds all location and speed data...(Maybe a Java Applet).

Ok basically what I would like to do is create an app using gps, which tracks the direction and speed the user is moving. now the next part is the part im not sure if it is possible. I need the app to either track other users movements or recieve info from other users about their movements(directions and speed). The other users would be using the same app but on seperate devices. The users would be within no more than 30 meters apart. Does anybody know if this would be possible, and how difficult it would be if possible? I'm trying to avoid using wifi but if this is not possible I may have to change my idea a bit and look into it... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

Hi Anirudh ,I did not try it but go to the site : http://developer.htc.com/adp.html download system image signed-dream_devphone_userdebug-img-14721.zipjavascript:void(0); and replace yours in SDK 1.6 . Pay attention that image should be for android 1.6. Regards.
