Android :: Incremental Loading Of Images

Aug 14, 2010

In my app I need to download a lot of images for data in a ListView. I do lazy loading and it works rather fast, but still there is a 1-3 secs delay before the first image shows up. My research in the delay shows that the data transfer takes 50% of the time.

Now, I believe that If I could do incremental loading of the images, I would be able to show half an image after just 75% of the delay, which is quite good.

I use Drawable.createFromStream which uses BitmapFactory.decodeResourceStream internally. But even though it takes a stream, it doesn't paint anything before all data is downloaded and decoded.

Do you know a way to load and paint images incrementally with the default Android lib? Or perhaps a good independent one out there?

Android :: Which Is Better Loading Of Images For ListView?

Jan 19, 2010

I am wondering if which of the two is better in loading images in a listview from web, is it by batch through some number of threads that are running simultaneously or one by one through thread queue? I have noticed (but I don't know if that is really the implementation) from the youtube app that the images are loaded by batch and it is kinda fast. Even for not only loading images but also requesting some data from the web as well. Does anyone have an idea?

I try to implements lazy loading of images in a listview. There is no android features to make this, so I should implement it by myself. Have anyone already done this? Take the solution care of scrolling and lazy loading new images and stop to load not more necessary images?

Android :: Lazy Loading Images In A ListView

Dec 8, 2009

I trying a hand at ListViews and my current experiment is aimed at displaying some data in a ListView. The data to be displayed in each row is simple: an image and some text. The images come from a remote server and the textual data is hardcoded. I have a class that downloads images using AsyncTask and caches the list of images fetched as SoftReferences in a LinkedHashMap. I am also passing a reference of the view to this class, so when the image download/cache read is complete the class will set appropriate Bitmap in the view.

Android :: Lazy Loading Images In ListView

Sep 22, 2010

I implemented the lazy-loading images in my ListView. I use a AsyncTask to download the image from the internet and bind it to the ImageView in the UIThread. It's working except that when I scroll the ListView vary fast, the downloaded images sometimes are binded into the wrong items in the list.I guess the problem is from the reuse of convertView in the BaseAdapter.

Android :: Lazy Loading Images In A ListView?

Feb 13, 2010

Here are 4 references that I have found for lazy-loading images into a listview in Android. The idea is to display a placeholder image, get the actual image in the background, update the ImageView in the list when the image is available. I've tried to do this in the simplest way possible using an AsyncTask in an Adapter. The outline of that approach is below. Is it flawed? Is there an agreed approach to handling this common task?

Android :: Loading Images As Drawable Objects From URL

Jul 30, 2010

I am presently using the following piece of code to load in images as drawable objects form a URL.
Drawable drawable_from_url(String url, String src_name) throws java.net.MalformedURLException, java.io.IOException { return Drawable.createFromStream(((java.io.InputStream)new java.net.URL(url).getContent()), src_name); }

This code works exactly as wanted, but there appears to be compatibility problems with it. In version 1.5, it throws a FileNotFoundException when I give it a URL. In 2.2, given the exact same URL, it works fine. The following URL is an sample input I am giving this function.
http://bks6.books.google.com/books?id=aH7BPTrwNXUC&printsec=frontcover&img=1&zoom=5&edge=curl&sig=ACfU3U2aQRnAX2o2ny2xFC1GmVn22almpg
How would I load in images in a way that is compatible across the board from a URL?

Android :: Refreshing Lazy Loading Images Into A ListView

Sep 11, 2009

This is a very common scenario: displaying images in a ListView which have to be downloaded from the internet.Right now I have a custom subclass of ArrayAdapter which I use for the ListView. In my getView() implementation of the ArrayAdapter, I spawn a separate thread to load an image. After the loading is done, it looks up the appropriate ImageView and sets the image with ImageView.setImageDrawable(). So the solution I used is kind of similar to this one: http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listviewThe problem I'm having is that as soon as I make the call to setImageDrawable() on the ImageView, the ListView somehow refreshes all currently visible rows in the list! This results in kind of an infinite loop. Code...

Android :: Images From Drawable Folder Loading Scaled

Oct 18, 2010

I recently rebuilt my project to target 2.2 from 2.1. In the old project, I did not specify a target SDK (the manifest did not contain something like:
<uses-sdk android:minSdkVersion="8" />).
This gave me an error in the console when running, but everything worked fine so I didn't fool with it.

The new project now uses <uses-sdk android:minSdkVersion="8" /> in the manifest. But now my drawables from the /drawable-nodpi/ folder are loading with scaling, making them much smaller and significantly changing the desired visuals. If I cut out the <uses-sdk android:minSdkVersion="8" /> tag from my manifest, they load properly without scaling.

Even when loading my images like so:
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inScaled = false; Bitmap bm = BitmapFactory.decodeResource(_resources, resId, opts);
They are still scaled when I declare the minimum SDK in the manifest, but not scaled if I remove that tag. How can I load them without scaling while still declaring the minimum SDK?

Android :: How To Loading Images (assets / Resources) Dynamically?

May 21, 2009

How do I load the image dynamically through the code? If its unclear, I mean, I want to load image files by name based on the condition in the code. If I use images as resources, the image names have to be hard coded. This is unacceptable to me. If I load image in a webview (with image src path dynamically), the time it takes to load is unacceptable to me. Can anyone suggest any other way to load the images dynamically?

Motorola Droid :: Loading All The Images?

May 5, 2010

I just received a brand new Droid from Verizon to replace my latest refurb Eris because of all the call problems i have had. I figured I could just swap the 8gb SD card I was using in my Eris (because it's a class 6) and put it in my Droid. But when I went to the gallery it started acting really strange. It seems it's having trouble loading all the images, and it's been kind of jumping around and behaving erratically. Is there anything I need to do to my card?

Android : Incremental Status Bar Notification Icon Contains Number Of Unread Mails

Dec 18, 2009

You know what I'm talking about: for example when you get multiple new emails the notification icon in the status bar is augmented with a little red circle that contains number of unread mails. Twitroid has the same icon. Any idea how it's done? I don't think (or so I hope) there are 10000 similar icons. Is this red circle generated and overlaid the notification icon?

Android :: Loading And Showing A Lot Of Images In ImageView - Frame By Frame Animation - Hangs In Certain Moments

Feb 18, 2010

I've created an application that show around 250 images in ImageView. Images are loaded one after another, 15-30 images per second. Basically the whole thing gives an illusion of a rotating 3D object, at least it should.

The problem is next, app hangs when loading certain images(i.e. I see a few seconds of fluid animation and then animation hangs, jump 10-15 frames(images) ahead and continues. It always happens at the same places in animation cycle.

I though that Android might not have enough resources to handle something like this, so I've resized images to half their size, but it did't help. I've tried buffering images but that did't help either(actually, maybe a little, I think that animation looks a little bit smoother).

And now the weirdest thing. I use the touch screen to allow users to "rotate" the 3D object on those images, and while rotating I again experience those hangs at exactly the same places as with the animation.

All images are in .png format and their size vary from 15kB to 40kB.

I use the following code for the animation:

Android :: Load Images In OpenGL Without Having Thin Outline Appear Around Images?

Nov 2, 2009

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?

Android :: Adding Some Nine Patch Images Breaks All Of My Other Images

Apr 6, 2010

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.

Android :: Loading Activity Darkens Screen - Loading Screen

I've looked through the documentation and I can't seem to figure out how to have the screen blured/greyed when I select an activity that may take a while to load.

This seems to be an Android standard (both the Camera app and the Camcorder app do it when first selected), but I don't see any documentation on it. I even tried looking through the source of these apps on git, but couldn't seem to find it.
