-or-
background:#ffffff url(file:///android_asset/calendar-date-icon.png)no-repeat;

This should be very simple, but I can't find the answer anywhere. How do I load an html file (which I assume I keep in res/raw folder) into a webview?
neither mWebView.loadUrl("file:///raw/about");
or
mWebView.loadUrl("file:///raw/about.htmal");
works.
What's the correct syntax or arrangement.
I published an application that stores data in a local database.
Now I have to publish an update to this application to fix some little bugs, but I am afraid that downloading and installing the update will delate the local database associated with the previous version.
I would like to know how the update system works. Will installing an update completely delete all the apk, files, databases associeted with the previous version?
If so, how can I avoid this in my code?

the question i have is simple but hard to put in words, ill give it a try anyways.i am trying to load a web page in web view,however the load time is a little high.is there anyway i can put the images in the assets folder and load them from there instead?if not, is there a way i can load the whole site from the assets folder, providing that my php files can still communicate with my internet database?i have already read most tutorials however they are pretty vague when it comes to concrete help.
View 2 Replies View RelatedI 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 have a app out right now that wont load images that are higher than 5mp but loads smaller ones. Im not sure if its 5mp or over 1mb, Im pretty sure its mp though, I have tested. How can I load pictures that are all sizes? My code is below, Please help, please post code not links, of must to links then links to code that can help.
Downloading The Image
CODE:...............
In my app I am downloading images from a remote server and putting it into a gallery and displaying it. The problem is that when i do it on the emulator it works absolutely fine but when i do it on the phone few of the images come and a few are null. I tried many ways but I am not able to find the perfect way. The images on my server are of 50 kb max. But still some are downloaded and rest are not. it would be really great if someone could help me asap coz i need to make this app live by this weekend.
Here is the code snippet to download the images from the server.
CODE:.........
Also is there any other way of loading the images in a seperate thread like it happens in the android market.
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?
I am stuck in an peculiar scenario, while developin an app in android.
My app, downloads image from internet and populates the same in a thumbnail format in the application.
As i am not aware of the number of picture's/thumbnails at design time, i am creating image view controls dynamically by using the below mentioned code.
CODE:...................
But in this scenario, all my images gets overlapped with each other. Wherein i want 3 images to be displayed on each row, which i am able to achieve through xml.
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?
View 3 Replies View RelatedI 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.

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. Code...
View 2 Replies View RelatedHere 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?

View 2 Replies View RelatedI 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.

How would I load in images in a way that is compatible across the board from a URL?
In my android application i am trying to download images from remote server dynamically ( no of images dynamically come ). for downloading all images it is taking 30 to 40 seconds mean time user has to wait to see the activity . But it is the worst case that loading activity after loading all images. I want to load activity first then load images one by one.

View 2 Replies View RelatedThis 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...
View 2 Replies View RelatedI 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?
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?
View 2 Replies View RelatedI 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?

I have tried to following to resolve the issue: Reset phoneCleared Gallery app cache and resetScrolling through the images in filmstrip mode
The photos appear in the new Photos app and on G+.
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:

View 2 Replies View RelatedI'm thinking of using WebView as a container for "Form" based JavaScript+DHTML applications. This is simple fill-out-forms like you have on the web, but now on mobile like for note taking, order taking, and the like.This is to allow web developers to build the bulk of the application - Javascript will perform validation, computations, etc.On the Java side, I only need to implement database CRUD operations, and a ListView to scroll over the forms.To minimize the learning curve on the JavaScript side, I've been thinking on how to emulate AJAX calls so that the web developers don't need to learn new methods to call on the JavaScript-Java bridge. Of course this isn't possible using XMLHttpRequest, so I'm thinking of adapting JQuery or other Javascript libraries for this purpose.
