Android :: Reading Pictures Written By Camera To SD Card
May 24, 2010
I 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?

I have HTC Desire, and I know that I have QuickOffice. The problem is when I put a word or excel file on the .quickoffice folder on my phone, nothing comes up on the mobile when I disconnect. Therefore I was wondering if anyone could recommend me a program where I can either write, or read written files like Word and excel files?

1) Is there a way to allow the camera to save pictures onto the SD card, as mine does not do so?
2) Within the Gmail app, is there a way to move messages from your inbox to other user-created folders? The Motorola Droid definitely had this option, but on the Incredible it looks like it only lets me apply a "Label", which I'm unfamiliar with, though this does not actually move the e-mail to that folder.

the Camera on my Eris will not take pictures due to an error saying it has insufficient file permissions to save pictures to my SD card. I have not unmounted my SD card since this has happened nor did I do it before. I have unmounted it before, but it was never a problem. The camera will not save pictures at all not matter what app is using the camera (Default Android Camera, Facebook, Photoshop Mobile).

My application writes data to a file in the SD card directly. There are no errors during the write. But, the file never shows up on the card, in the file browser (on the device - I use Glance). Where did the file go? When trying to browse the device from my desktop, I notice the USB Mass Storage option is missing guess that's expected since others in the forum explain that it was removed in this version. But, I can't get my PC to browse the memory card when it's stored in the phone. This all just seems to add up to a flaky memory management problem, but I can't be sure.

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

If I am going to be reading files from the SD Card, where do I put them during development? Also, when I install the app, will it include these files and put them to the SD Card?

Sorry to already be asking stupid new guy questions, but I just made the switch to Android and my new Droid 2 apparently isn't reading my SD card. Any ideas as to why this may be and what I can do to fix it? Keep in mind I'm not overly tech savvy (but not incompetent).

My friend's Epic/PC will not pick up his micro SD card. I told him to try what it said in the manual to reformat it, but the problem is that the phone will not even read the card in the first place. Do you think the card has died already?

how to apply to lag fix by partitioning my sd card. I followed the guide to the t using Paragon Hard Disk Manager. When I deleted my external SD card partition, it wouldn't let me re-partition it. Now my computer won't even recognize my phone. When I go into settings->SD card and phone storage, both the internal and external SD card show "Unavailable" under the space heading. The unmount and format options are greyed out as well. What do I need to do to get my phone back the way it was? I would just like my phone back the way it was and would like to get this lag fix working. Here are the video tutorials I followed and the original site I found.

I have a rooted HTC Hero (Sprint), Fresh, Gumbo Kernel that runs wonderfully. Lateley however, my phone is not reading my sd card. Im unaware of the class, but it is an 8gb scan disk minisd. It has worked for over a year. I try to copy my information onto my desktop to reformat the sd, but it stops in the middle of the transfer. I have tried to find info on this issue, and I apologize if a thread has already been started.

Like the title says why are apps allowed to read the contents of files on the SD card without asking permission? Apps have to ask to read SMS, Calendar, and everything else. It seems like a huge security hole to me.

I searched the Incredible forums and sub forums and could not find an answer to this question, though I am sure it has been asked: If I want to go from my stock 2 GB card to a new card, and I want to preserve data AND have all apps still be able to read whatever data they were reading off the card, do I just transfer the files from one card to the other? I bet the only thing I need to make sure of is that new card is formatted with the same file system as the original card, right? I know copying data from one card to the other will preserve data, but I want to make sure I have no problems with apps, either, after inserting the newer card.

Is there any App that will help take better pictures? I'm tempted to call Verizon up because I think my Camera isn't functioning at all.
I can take a picture of my daughter, in full light, and it comes out blurry as all hell.

I've been trying to write an application that uses the Camera App to take a picture. So far, the only thing I've been able to get back successfully is a tiny bitmap picture. I've found several other posts related to this topic that have code that is reported to work, but it does not work for me. I'm hoping someone can steer me in the right direction. Below is the code I am using currently, but it causes the application to blow up.
private void takePicture(final int x, final int y, String description) {
// create a file on the SD card
File file = new File(Environment.getExternalStorageDirectory(),
"tmp_" + String.valueOf(System.currentTimeMillis()) + ".jpg");
// Create the URI that tells the camera where to put the picture.
mOutputFileUri = Uri.fromFile(file);
statusLine.setText("URI => " + mOutputFileUri);
mIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE)
.putExtra(MediaStore.EXTRA_OUTPUT, mOutputFileUri)
.putExtra(PIC_X, x) // x coordinate of square
.putExtra(PIC_Y, y) // y coordinate of square
.putExtra(PIC_DESCRIP,description)
.putExtra("return-data", true) ;
startActivityForResult(mIntent, PIC_FROM_CAMERA);
}
Ultimately, I want to be able to get the picture back and do two things with it: create a 64x64 icon that is displayed by the Android application, and upload the picture to a web application. I'm running this on the emulator using Android 2.0

Hi. im having a trouble getting Android's camera to work. i started CameraActivity Intent from MapActivity (when i start camera activity, i unresgister all listeners used in map activity), and when i call takepicture method, it just exits camera activity and return to map activity dumping strange msg showing below.
the camera sounds off the shutter-sound and it crashes camera activity. sometimes it succeeds, and sometimes doesn't.

Just installed Camera Zoom FX, took a couple of pics. They immediately appear in a little square at the top left of my screen while still in camera mode after I click "save". However, no matter if I click on that little icon of the pic I took, or go to the Gallery on my Droid, either way it just comes up with the screen saying "No Media Found" help! Where are the pictures I am taking going?

I'm using the default camera API of Android 1.6 like this:
Intent photoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); photoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File (Environment.getExternalStorageDirectory(), "test.jpg"))); startActivityForResult(photoPickerIntent, 1);
But the image is saved on very low resolution 512 x 348. I added the QUALITY property but it doesn't make sence: photoPickerIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); There are many more posts on the internet talking about this issue but there's no solution (jet). Is it solved on 2.0??? I realy need the high resolution image (3MP).

I am working on a program that opens up the camera on a button click, snaps a photo and takes that photo and stores it in a new class (listview.java) that will be accessed from the main menu. My code to snap a pic is: Code...
how do I go about saving that new bmp file to that different class?
I tried to put photoResultView in my listview.java class as so: Code...
but the program crashes everytime I try and save the pic I snapped - anyone have any ideas or tutorials for doing this?

My camera won't take properly colored pictures any more. It started out as an intermittent problem but now it's just all the time and it really bugs me. The camera on these phones sucks to begin with but it did come in handy some times. This is the kind of pictures it takes now.

When you are taking a picture on an and device, you can send it. There are apps, which are pushing their actions into these send-list (Like Twidroid, which adds a listitem called "Send Tweet" in that menu).
So, how is it possible to add such a menu point into that menu? For my app, I want to make it possible to take pictures from both (The App itself and via the real camera-send-list) and save them on the sdcard.
