How do we do programmatic reading of a barcode that is captured using a mobile phone camera? For example, how do that using iPhone or Android or Java ME? Do we need separate hardware to read bar code or can we do image manipulation

On the Google Products page, from an Android device, there is a "scan barcode" button that launches a 3rd party barcode scanning app, which returns results back to the browser. 1) How did they do this? 2) Is this available for any web developer to do, or a Google -> Google api only?

Is there any way of reading a barcode from your mobile browser? I'm sure I'm missing something here. Every time I find a barcode while browsing on my phone I then have to open the same web page on a desktop / laptop so I can snap it with the barcode reader on my phone. I'm probably just being stupid but can I get my phone browser to read the barcode? Do any browsers offer this as a plugin?
View 2 Replies View RelatedI want to access camera pictures and camera pictures only. I could not find a specification of how the default camera application stores pictures...
1) Is /sdcard/DCIM a standard of any kind? On the Android devices I've used, it looks like the default camera app always writes to this location. Are there devices where pictures are written to a different location? 2) Is it specified that camera JPEGs will always be accessible on the file system? (And not in some private database for example?)
I'm hoping that if the above two are true, then I can simplify my code by simply reading the jpeg's in /sdcard/dcim. Or do I have to use MediaStore.Images.Media.query() for reliable access to camera images?

When I use my camera, camcorder, or just open up picture gallery or vid my phone will just restart, no clue why. I told tmobile that and she said it could be my SIM so I get a new one and that doesn't help. I'm about ready to call them and get a new one through my warranty.

Anyone else having this issue? Any thoughts?

Has the name changed or have somebody a good tutorial for android 1.6 and the camera? If I press a button, I want to open the Camera and make a picture. After that i want to save the picture on a sdcard and go back to my activity.

I have this project in mind where I'd like to have such feature - to take a picture using the camera (already developed this) and then make it watermarked. So basically just take the .jpeg file and then blend it with some .png file that is semi transparent.

What I is that after taking a picture, the crop/editor comes up, with a fixed aspect ratio of 1:1.

View 1 Replies View RelatedHi Guys! I'm coding a little app, but I don't know what I'm doing wrong. The App does the following: - Launches a Service which listens for an sms, then captures a picture with the cam and sends it to a predefined email adress. (no, i'm not trying to spy somebody out... I'm using the app to get a "3G-Webcam", sort of at least)
The problem: My App works great in the emulator, but as soon as I try it on my HTC Magic (cm6, android 2.2) it stops working.

The permissions are all set, even the write to SD-card. What am I missing?

I'm writing an application for Android. I need to make some image processing on the picture taken from camera.I use Camera.PictureCallback to get the photo, and I get picture in byte array.The problem is I want to make operations on every pixel of photo (some filtering and other stuff) so I guess, have photo in byte array is not a bad idea. But I don't know how interpret information in this byte array... The only way I know to make the processing is use BitmapFactory.decodeByteArray() and then use Bitmap object. Is this a good way to handle a lot of image processing?
View 1 Replies View RelatedI'm trying for my app to create a picture this way... It works fine, except when doing this, the picture is written in the "Camera" folder (/sdcard/dcim/Camera). Since the picture was not taken with the camera, this is not desirable. Is there any way to put it directly in dcim?

It appears these messages appear.. I guess my question is, why is the picture size stuck at 213x350? If I set my picture size to 640x480 it fails.

I am facing a problem; when I try to save the picture, the app will auto stop. but it does not happen everytime.
Next is the sourcecode.

I just don't get it: when I use the camera with an intent and also specify an output file, the returned image is always very small on many devices (e.g. Motorola Milestone 2.1, HTC Desire 2.1, Emulator 2.1, Emulator 2.0.1) but not on all (e.g. Nexus One). Here's what I do to bring up the camera app:
private final static String TEMP_PHOTO_FILE = Environment.getExternalStorageDirectory() + "/TEMP_PHOTO.JPG"; ..............
I am trying to take picture by G1 camera.
I have tried almost everything i was able to find on the net about this topic. It seams there should be intent with action "android.media.action.IMAGE_CAPTURE" which really starts camera application and returns captured image. But captured image is scaled to 0.25 of original size. Another possibility I have found is to pass uri where to save captured image. I went through all available sources of camera application and it should work but does not.
For illustration, I am doing following in my example activity which creates new image, but after returning from camera, image is still empty:
CODE:..................
I am ready to write my own capturing application, but it is quite hard and I would like to reuse.
Do you know correct intent action name and extra name to pass to capture image?
As title - having tried everything I could find already suggested, I've completely run out of options. I'm unable to set the picture size taken by the camera on the Samsung Galaxy.
I don't set preview size anywhere and I've tried the ShutterCallback trick. On checking the camera parameters before and after attempting to change the size, I get the correct results - the camera *reports* that its size has now been changed... however, the size of the byte array I'm receiving in the onPictureTaken() callback is only consistent with the camera's default (enormous) image - and forces an OutOfMemoryError when I attempt to decode it into a bitmap!
It looks like I'm having a similar issue to this user: http://groups.google.com/group/android-developers/browse_thread/threa... - but unfortunately it looks like no solution was found then, either :
No matter what I do I cannot make the final camera image be smaller than the gigantic 5MP which effectively crashes the poor old BitmapFactory.
The ShutterCallback trick is in use. Does somebody have some other ideas?
Boy, it feels like going all the way back to J2ME.
On the G1 camera app, there's a handsome looking camera button which you can press to signal the app to take the picture. It's a round button with a little camera icon in it. Is that button resource available in android.R? I'd like to use it in my own app if possible?
View 2 Replies View RelatedI ask if there is a simple way because there is a google issue report saying that using decodeByteArray isn't possible. But that report originated in 2008 and I was hoping there was a solution not posted on there. The method listed on the issue report was to decode the format yourself, but I'd prefer to not have to put that in and slow down the program.
