How to load one image in android WITH OUT download

know anyone of you how can I use one photo from URL with out download? Because I can have a lot of images and if my application CANT download all of them...
I've found one function on web he how can do this but it don't work.
public static Drawable LoadImageFromWebOperations(String url) {
try {
InputStream is = (InputStream) new URL(url).getContent();
Drawable d = Drawable.createFromStream(is, "src name");
return d;
} catch (Exception e) {
return null;
}
}
I really need that, so have anyone any idea?

You can use Picasso lib for downloading image from url:

Example:
Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);

Downloading and showing images in Android

I want download some images from an android application, and then show these images.
I want know where I have to put my downloaded images and how to refer to them in order to show them, for example using them as background of a View object.

Here is an example of downloading an image from a URL and showing it in an ImageView.
This is the download method:
void downloadFile(String fileUrl) {
try{
InputStream is = (InputStream) new URL(fileUrl).getContent();
Drawable d = Drawable.createFromStream(is, "src name");
imgView.setImageDrawable(d);
} catch (IOException e) {
e.printStackTrace();
}
}

Displaying Images parsed from JSOUP in android?

I've been trying to develop an android app that parses through a specific (business's) website, and display the head image of the site on the top, news on the bottom, and have buttons below it that will open a new activity to display the schedule for the business, and any other information about the business. I decided to use JSOUP, which I am very new to, but I can't figure out how it is that I go about displaying images. I tried something like this, but it didn't work:
ImageView image = (ImageView) findViewById(R.id.headImage);
Document doc = Jsoup.connect("http://www.example.com/").get();
Elements divs = doc.select("img");
for (Element div : divs) {
Log.d("web Stuff",div.text());
text.setText(text.getText() + "\n" + div.text());
Element myImage = div;
String url = myImage.absUrl("src");
image.setImageDrawable(Drawable.createFromPath(url));
}
how am I supposed to correctly implement something like this?

I would load the image in a new thread if you want to do it for more than one image.
public void run() {
URL url = new URL(url);
Bitmap bitmap = BitmapFactory.decodeStream(url.openStream());
}
when the Thread is finished you can set the image of the imageview.
image.setImageBitmap(bitmap);

Drawable drw =LoadImageFromWebOperations(image_url);
im.setImageDrawable(drw);
private Drawable LoadImageFromWebOperations(String strPhotoUrl)
{
try
{
InputStream is = (InputStream) new URL(strPhotoUrl).getContent();
Drawable d = Drawable.createFromStream(is, "src name");
return d;
}catch (Exception e) {
System.out.println("Exc="+e);
return null;
}
}

creating a drawable from sd card to set as a background in android

I am trying to use an image from the sd card and set it as the background for a relativelayout. I have tried other solutions that i have found here and elsewhere but they havent seemed to work for me. here is my code. I have commented out other ways that i have tried and didnt work. the only thing that worked for me was using setBackgroudnResource and using a resource from the app, but this was just to test to make sure mRoot was set up correctly. when I have tried all the other ways, it just doesn't set anything. Anyone know what I am doing wrong, or if there is a better way to do this?
//one way i tired...
//String extDir = Environment.getExternalStorageDirectory().toString();
//Drawable d = Drawable.createFromPath(extDir + "/pic.png");
//mRoot.setBackgroundDrawable(d);
//another way tried..
//Drawable d = Drawable.createFromPath("/sdcard/pic.png");
//mRoot.setBackgroundDrawable(d);
//last way i tried...
mRoot.setBackgroundDrawable(Drawable.createFromPath(new File(Environment.getExternalStorageDirectory(), "pic.png").getAbsolutePath()));
//worked, only to verify mRoot was setup correctly and it could be changed
//mRoot.setBackgroundResource(R.drawable.bkg);

You do not load a drawable from SD card but a bitmap. Here is a method to load it with the reduced sampling (quality) so the program will not complain if the image is too large. Then I guess you need to process this bitmap i.e. crop it and resize for the background.
// Read bitmap from Uri
public Bitmap readBitmap(Uri selectedImage) {
Bitmap bm = null;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2; //reduce quality
AssetFileDescriptor fileDescriptor =null;
try {
fileDescriptor = this.getContentResolver().openAssetFileDescriptor(selectedImage,"r");
} catch (FileNotFoundException e) {
e.printStackTrace();
}
finally{
try {
bm = BitmapFactory.decodeFileDescriptor(fileDescriptor.getFileDescriptor(), null, options);
fileDescriptor.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return bm;
}
The Uri here can be supplied from a gallery picker activity.
The image then can be saved into application resources and loaded into an imageView
private void saveBackground(Bitmap Background) {
String strBackgroundFilename = "background_custom.jpg";
try {
Background.compress(CompressFormat.JPEG, 80, openFileOutput(strBackgroundFilename, MODE_PRIVATE));
} catch (Exception e) {
Log.e(DEBUG_TAG, "Background compression and save failed.", e);
}
Uri imageUriToSaveCameraImageTo = Uri.fromFile(new File(BackgroundSettings.this.getFilesDir(), strBackgroundFilename));
// Load this image
Bitmap bitmapImage = BitmapFactory.decodeFile(imageUriToSaveCameraImageTo.getPath());
Drawable bgrImage = new BitmapDrawable(bitmapImage);
//show it in a view
ImageView backgroundView = (ImageView) findViewById(R.id.BackgroundImageView);
backgroundView.setImageURI(null);
backgroundView.setImageDrawable(bgrImage);
}

File file = new File( url.getAbsolutePath(), imageUrl);
if (file.exists()) {
mDrawable = Drawable.createFromPath(file.getAbsolutePath());
}

I suggest checking that the drawable is being loaded correctly. Some things to try:
Try using a different image on the sd card
Put pic.png in R.drawable and make sure mRoot.setBackgroundResource() does what you expect
After loading the drawable, check d.getBounds() to make sure it is what you expect

Invoke the image directly from website to our app

I want to use the image directly from website. I did not place that image in drawable folder. For this purpose what can I do?
Please, give me some suggestions.

I've written a function that creates a Drawable from an image url, look below:
private Drawable downloadThumbnails(String url) {
Drawable d = null;
try {
InputStream is = (InputStream) this.fetch(url);
d = Drawable.createFromStream(is, "src_from_stream");
return d;
} catch (MalformedURLException e) {
} catch (IOException e) {
}
return null;
}
public Object fetch(String address) throws MalformedURLException, IOException {
URL url = new URL(address);
Object content = url.getContent();
return content;
}
then use it like this:
Drawable img = downloadThumbnails("http://yoururl.com/image.png");
yourImageView.setImageDrawable(img);

I strongly recommend using Picasso:
Picasso.with(context).load("http://an.url.com/lovely_cats.png").into(imageView);
It has a lot of usefull functions that allows you to:
crop the image
resize the image
rotate the image
fit an image into the target view
replace not downloaded file with local placeholder
an even more - mostly in a single line (or call).
