Android :: Droid List Of All Images Available?
Jun 11, 2010
I m making an application which requires me to list all the images available on the SD-Card of the phone.
i tried querying the ContentResolver way i.e.
Cursor image = getContentResolver().query(Images.Media.EXTERNAL_CONTENT_URI, new String[]{Images.Media._ID,Images.Media.DATA,Images.Media.DISPLAY_NAME}, null, null, null);
but without any result. Is there any way i can get the list or if thats not possible then is there any possible intent (e.g. PICK) by which i can allow the user to select a file and then access the path of the file the user selected?

So how should I pass the images out from the database into the list view (in fact, I only save the image uri in db). I am able to save and retrieve images individually and display it on the screen. But how do I pass a bitmap and display it in a list view.

I'm working on an Android application that needs to look at what images a user has stored. The problem is that if the user has the sdcard mounted via the USB cable, I can't read the list of images on the disk. Does anyone know of a way to tell if the usb is mounted so that I could just pop up a message informing the user that it won't work?

I have a list of 70 text items with image icons(which are stored in drawables folder).
If I launch application the first time and scroll the list slowly - the exception doesn't occur.
When the application is launched the first time and I scroll the list with 'fling' action the following exception occurs:
COD:.....................
After that, if I kill the application with DDMS, start it again and scroll it with 'fling' action, exception doesn't occur. So the exception arises only if application is installed and launched the first time.
Here is the adapter I use for the list:
CODE:................
Is there a way to avoid the exception? Should I catch the exception and escape the memory somehow?

I am trying to modify this example:
http://developer.android.com/resources/tutorials/views/hello-gridview.html
But instead of displaying images that are resources, I want to display Drawables that I currently am storing in a List.
Can anyone instruct me on how I would modify
code...
To display my drawable items instead?

here's what I want :-
An activity using Scrollable Tabs + Swipe - To display a predefined list of images.
This activity will be opened by a Listview activity, containing a list of Items that are really just the Names of the Images.
Corresponding to this list of Names of images are the URLs where these images are stored...
Names in one list , their URLs in another.
I want to obtain the list selection index from the listview activity, go to the activity displaying images and use that index to retrieve the URL and then display the image in it.

I am building a android aplication which will be consuming a json file from the internet. This json file contains a list of news from a particular website. Each json object contains information such like title, summary, descripition and web links for the news thumbnail and the original image.
I will be displaying in a listview three information: the news thumbnail, the title and the summary. Here resides my problem. I dont want to load all thumbnails from the internet if they wont be displayed. What I am trying to say is that why download a thumbnail from the 30th news if the user wont scroll down the image. So, i will, initially only download the thumnails from those news that are being displayed in the screen and when the user scrolls down to see more news, as soon as the list item appers to the screen i want to download the image and then display.
Is there a way to achieve this? Is it possible to find out if the list item is on the screen? I have been searching all over the internet for a solution for this but i am running out of ideas.

I want to send friends some images on mms!And when I turn it to landscape mode, the list is even shorter! It won't allow me to scroll through my apps to send the image.

I'm basically using the same method of loading bitmaps in OpenGL that the SpriteMethodTest example uses and have been unable to get rid of an annoying outline that appears around all of my images.
For example, If I were to load an image of a white circle on a white background, I would expect to see nothing. Instead, I would see my circle because its edge would be gray. In SpriteMethodTest, I replaced the background image with white and was able to see that the edges of the android images flying around also don't seem to be rendered correctly.
Does anyone know how to load images in OpenGL without having a thin outline appear around the images?

I'm working to convert some background images to nine patch so they scale better on different phones.
The problem is that if I have the following resource structure: drawable-hdpi/background.png drawable-hdpi/button.png drawable-mdpi/background.png drawable-mdpi/button.png drawable-ldpi/background.png drawable-ldpi/button.png and then I drop a new drawable-hdpi/background.9.png file into the mix, it breaks button.png during the pre-compile. The error is "No resource found that matches the given name (at 'background' with value '@drawable/button').Simply removing that one nine patch file fixes the build. Should I be able to have some nine patch images and some normal ones, or to have nine patch only in hdpi but not mdpi or ldpi? This is Eclipse 3.5.1 with the latest ADT.

I have 24 .png images and a ImageView. On user touch I change the ImageView to be one of the 24 images. I'm currently doing setImageResource(R.drawable.hour_1);, but there is a slight delay after I touch the screen and the ImageView actually changes. I figure the delay is the resource being loaded, but I can't find a better way to do this.

I am developing a Java Android application that displays web content from the assets folder in a web view. I had no problem getting this content to display in the application but I am confused as to why my images are not displaying properly. I'm working with a Motorola Droid that is supposed to be 480x854 resolution. When I create banner images using these dimensions and attempt to display them in the web view they're enormous and they flow off of the screen. It doesn't appear that the web view is actually 480x854. Can somebody let me know what I am missing here? I do not know what size to set the images to so they are just right.

I need to upload an image to a remote PHP server which expects the following parameters in HTTPPOST:
*$_POST['title']*
*$_POST['caption']*
*$_FILES['fileatt']*
Most of the Internet searches suggested either :
Download the following classes and trying MultiPartEntity to send the request:
apache-mime4j-0.5.jar
httpclient-4.0-beta2.jar
httpcore-4.0-beta3.jar
httpmime-4.0-beta2.jar
OR
Use URLconnection and handle multipart data myself.
Btw, I am keen on using HttpClient class rather than java.net(or is it android.net) classes. Eventually, I downloaded the Multipart classes from the Android source code and used them in my project instead.
Though this can be done by any of the above mentioned methods, I'd like to make sure if these are the only ways to achieve the said objective. I skimmed through the documentation and found a FileEntity class but I could not get it to work.
What is the correct way to get this done in an Android application?
