All I want to do is display a URL image. Does anyone have a template I could use that already displays an image that I can possibly modify? I've been looking all over the internet and the only answers I've found are extremely complex.I'm very good at learning something once I can get it to work from my end then proceed to analyzing the code.I am VERY new at Android programming.

I have a Main class with has onCreate() method. in that method i have made the MapFile class' object.and called its readFile() and readIndex() methods. in readIndex() method i call another class named MapTile where i read the images tiles from my binary file and there i have to display my image.now question is how can i display image without putting my code into onCreate(Bundle savedInstanceStare) method.i am trying this way but on first line it gives me null pointer exception.
ImageView image = (ImageView) findViewById(android.R.id.icon); Bitmap bMap = BitmapFactory.decodeByteArray(imageTile, 0, imageTile.length);image.setImageBitmap(bMap);
I'm trying to display an image using a URL. When I run the code I get an error telling me the application has stopped unexpectedly. Can anyone see what's wrong in my code.
Bitmap bmImg; URL myFileUrl =null; try {
myFileUrl= new URL("http://www.starling-fitness.com/wp-content/ 240384vBdA_w.jpg");
} catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace();
} try { URLConnection conn= (URLConnection)myFileUrl.openConnection();
conn.setDoInput(true); conn.connect(); int length = conn.getContentLength();
int[] bitmapData = new int[length]; byte[] bitmapData2 = new byte[length];
InputStream is = conn.getInputStream(); bmImg = BitmapFactory.decodeStream(is);
/*timetableImage.setImageBitmap(bmImg);*/ setContentView(R.layout.timetable);
ImageView iv = (ImageView)findViewById(R.id.timetableImage); iv.setImageBitmap(bmImg);
} catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace();
}
I'm creating a simple application for Android which should display an image which is located on remote HTTP server. Which is the best way to do this: should it write the image to some temporary file, or just load it to RAM (in this case, how to load image to ImageView from byte array)?

I want to save what ever displaying in a canvas as a jpg image, how can i do it?
Currently I'm successfully loading and displaying an image from a webserver using the code below.
URL imgURL = new URL("http://www.xxx.com/myimage.png"); URLConnection conn = aURL.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); bm= BitmapFactory.decodeStream(bis); bis.close(); is.close();
canvas.drawBitmap(bm, 0, 0, null);
What I want to do is load it from a resource. I've put myimage.png into res/drawable and referenced the bitmap as follows :-
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.myimage);
However when I try to display it with canvas.drawBitmap(bm, 0, 0, null); I get a Force Close. What am I missing?

I want to display a fancy 'loading' image at my app's startup time.
The problem: my startup code is mostly GUI related, hence needs to run on UI thread.
Is there a way to do both - that is run UI-related code on UI thread while an image is displayed to the user?
I use http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview/3068012#3068012 to load images in a ListView and a GridView. It works but the images are loaded form bpttom to top. How to fix that?
Bonus Question: Can I use a loading animation in a image view while the real image is loaded? Right now it's just a default image.
It will be helpful if any one can help me out in understanding the concept of radio,flash,system image in android mobile device. Also why are they required? and what is their role in Device?

I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images. (these images will eventually come from the phones camera, but I will cross that bridge later!) My images are currently stored in the drawable folder in my project.As a first step I want to just have the user click on an image and it pops up full screen, just so I know how to get reference to it, but I am struggling. Evetually I want the user to click an image, then a window/activity(?) will open asking them for a bit of text. This will then be store in sqllite against the image. Code...

Just wondering if its possible to use the built in image viewer to display an image sourced from a database. I'm hoping I can pass the byte[] as an extra to the ACTION_VIEW intent, but can't find any docs on it so far. Alternatively I'll have to roll my own viewer or first write the image out to a file and pass that to the intent.
