I have been searching around but cannot find solution. My guess is that I probably wanted to get the bitmap from the canvas, but I can't find ways to get it. Then I try to set an empty bitmap into the canvas and draw on the canvas, and save the bitmap... but I got an empty bitmap..........

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)?
View 1 Replies View RelatedCurrently 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 am using following code to capture image through camera and then displaying it.
The problem , I am facing is when i take picture and press done button it does not display that taken image in my activity.

I need a small help on rotating one image around its center of axis among multiple images which are drawn to canvas in android.
I am loading images to canvas like below.
canvas.drawBitmap(mMachineBackground, 0, 0, null);
canvas.drawBitmap(mMachineRotator, 0, 0, null);
I want to rotate only the second bitmap around its center of axis instead of rotating the entire canvas(which includes first bitmap also).
So here's the problem. I am displaying a big image in ImageView and need to find it's position relative to the image.

At canvas there are many methods (canvas.rotate (35); canvas.drawBitmap (myBitmap, x, y, null); and many other things), but the method of mirror reflexion of image is absent (or I have not found it). At Bitmap too not that is not. Is it possible to reflect horizontally on canvas the image given Bitmap?

I'm new to the Desire, and despite reading through the full pdf manual, I can't work out how to save a picture I've been sent (in an MMS) to my photos, so I can use it for a caller ID. Also, I can't find an option to send a Multimedia message. When I open messages, to write one, it goes straight to a plain text one.
View 2 Replies View RelatedI need to know how he takes drawable object. I'm collecting some ImageView objects in array, they have background images that are rather big in resolution so they take lot of memory...
I have read somewhere that it will automatically create image with resolution that my imageView have, so i think it will take less memory than first one. Please tell me, if i set scaleType property, will it scale that image? Will that help me to save memory?
