I used the code below to fetch the image from a url but it doesn't working for large images.
Am I missing something when fetching that type of image?
imgView = (ImageView)findViewById(R.id.ImageView01);
imgView.setImageBitmap(loadBitmap("http://www.360technosoft.com/mx4.jpg"));
//imgView.setImageBitmap(loadBitmap("http://sugardaddydiaries.com/wp-content/uploads/2010/12/how_do_i_get_sugar_daddy.jpg"));
//setImageDrawable("http://sugardaddydiaries.com/wp-content/uploads/2010/12/holding-money-copy.jpg");
//Drawable drawable = LoadImageFromWebOperations("http://www.androidpeople.com/wp-content/uploads/2010/03/android.png");
//imgView.setImageDrawable(drawable);
/* try {
ImageView i = (ImageView)findViewById(R.id.ImageView01);
Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL("http://sugardaddydiaries.com/wp-content/uploads/2010/12/holding-money-copy.jpg").getContent());
i.setImageBitmap(bitmap);

}

String string2) {

Drawable d = Drawable.createFromStream(is, "src");
return d;
} catch (MalformedURLException e) {
e.printStackTrace();

} catch (IOException e) {

return null;

}
You're trying to download the Large Image from within the UI Thread....This will cause an ANR (Application not Responding)
Use AsyncTask to download the images, that way, a seperate thread will be used for the download and your UI Thread wont lock up.
see this good example that loads image from server.
blog.sptechnolab.com/2011/03/04/android/android-load-image-from-url/.
If you want to download the image very quickly then you can use AQuery which is similar to JQuery just download the android-query.0.15.7.jar
Import the jar file and add the following snippet
AQuery aq = new AQuery(this);
aq.id(R.id.image).image("http://4.bp.blogspot.com/_Q95xppgGoeo/TJzGNaeO8zI/AAAAAAAAADE/kez1bBRmQTk/s1600/Sri-Ram.jpg");
// Here R.id.image is id of your ImageView
// This method will not give any exception
// Dont forgot to add Internet Permission
public class MyImageActivity extends Activity
{
private String image_URL= "http://home.austarnet.com.au/~caroline/Slideshows/Butterfly_Bitmap_Download/slbutfly.bmp";
private ProgressDialog pd;
private Bitmap bitmap;
private ImageView bmImage;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
bmImage = (ImageView)findViewById(R.id.imageview);
pd = ProgressDialog.show(this, "Please Wait", "Downloading Image");
DownloadWebPageTask task = new DownloadWebPageTask();
task.execute(new String[] { image_URL });
// You can also give more images in string array
}
private class DownloadWebPageTask extends AsyncTask<String, Void, Bitmap>
{
// String --> parameter in execute
// Bitmap --> return type of doInBackground and parameter of onPostExecute
#Override
protected Bitmap doInBackground(String...urls) {
String response = "";
for (String url : urls)
{
InputStream i = null;
BufferedInputStream bis = null;
ByteArrayOutputStream out =null;
// Only for Drawable Image
// try
// {
// URL url = new URL(image_URL);
// InputStream is = url.openStream();
// Drawable d = Drawable.createFromStream(is, "kk.jpg");
// bmImage.setImageDrawable(d);
// }
// catch (Exception e) {
// // TODO: handle exception
// }
// THE ABOVE CODE IN COMMENTS WILL NOT WORK FOR BITMAP IMAGE
try
{
URL m = new URL(image_URL);
i = (InputStream) m.getContent();
bis = new BufferedInputStream(i, 1024*8);
out = new ByteArrayOutputStream();
int len=0;
byte[] buffer = new byte[4096];
while((len = bis.read(buffer)) != -1)
{
out.write(buffer, 0, len);
}
out.close();
bis.close();
byte[] data = out.toByteArray();
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
}
catch (Exception e)
{
e.printStackTrace();
}
}
return bitmap;
}

How to load image from URL and save that on memory of device in android? Dont say me use Picasso or oser laibrary.
I need to:
If device get internet conection I load image to ImageView from url and save it on memory of device, else I need to load one of save image to imageView. Thank`s for helps
P.S. Sorry me, I can make some mistakes in question because I don`t very good know English.
This my class:
public class ImageManager {
String file_path;
Bitmap bitmap = null;
public Bitmap donwoaledImageFromSD() {
File image = new File(Environment.getExternalStorageDirectory().getPath(),file_path);
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeFile(image.getAbsolutePath(),bmOptions);
return bitmap;
}
private void savebitmap() {
File file = new File("first");
file_path = file.getAbsolutePath();
try {
FileOutputStream fileOutputStream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90,fileOutputStream);
} catch (Exception e) {
e.printStackTrace();
}
}
public void fetchImage(final String url, final ImageView iView) {
new AsyncTask<String, Void, Bitmap>() {
protected Bitmap doInBackground(String... iUrl) {
try {
InputStream in = new URL(url).openStream();
bitmap = BitmapFactory.decodeStream(in);
savebitmap();
} catch (Exception e) {
donwoaledImageFromSD();
}
return bitmap;
}
protected void onPostExecute(Bitmap result) {
super.onPostExecute(result);
if (iView != null) {
iView.setImageBitmap(result);
}
}
}.execute(url);
}
}
Try to use this code:
Method for loading image from imageUrl
public Bitmap getBitmapFromURL(String imageUrl) {
try {
URL url = new URL(imageUrl);
HttpURLConnection connection = (HttpURLConnection)
url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream inputStream = connection.getInputStream();
Bitmap imageBitmap = BitmapFactory.decodeStream(inputStream);
return imageBitmap;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
And You should use it in a separate thread, like that:
new Thread(new Runnable() {
#Override
public void run() {
try {
Bitmap bitmap = getBitmapFromURL(<URL of your image>);
imageView.setImageBitmap(bitmap);
} catch (Exception e) {
e.printStackTrace();
e.getMessage();
}
}
}).start();
But using Picasso - indeed a better way.
Update:
For saving Bitmap to file on external storage (SD card) You can use method like this:
public static void writeBitmapToSD(String aFileName, Bitmap aBitmap) {
if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
return;
}
File sdPath = Environment.getExternalStorageDirectory();
File sdFile = new File(sdPath, aFileName);
if (sdFile.exists()) {
sdFile.delete ();
}
try {
FileOutputStream out = new FileOutputStream(sdFile);
aBitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
}
}
Remember that You need
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
for it.
And for loading `Bitmap` from file on external storage You can use method like that:
public static Bitmap loadImageFromSD(String aFileName) {
Bitmap result = null;
if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
try {
FileInputStream fis = new FileInputStream(new File(Environment.getExternalStorageDirectory(), aFileName));
result = BitmapFactory.decodeStream(fis);
fis.close();
} catch (FileNotFoundException e) {
Log.d(TAG, "loadImageFromSD: " + e.getMessage());
} catch (IOException e) {
e.printStackTrace();
}
}
return result;
}
You need
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
to do this.
Update 2
Method getBitmapFromURL(), but ImageView should be updated from UI thread, so You should call getBitmapFromURL(), for example, this way:
new Thread(new Runnable() {
#Override
public void run() {
try {
final Bitmap bitmap = getBitmapFromURL("<your_image_URL>");
runOnUiThread(new Runnable() {
#Override
public void run() {
imageView.setImageBitmap(bitmap);
}
});
} catch (Exception e) {
e.printStackTrace();
e.getMessage();
}
}
}).start();
I had this same issue and I hope this helps. First, To download Image from URL into your app, use the code below:
private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
ImageView bmImage;
public DownloadImageTask(ImageView bmImage) {
this.bmImage = bmImage;
}
protected Bitmap doInBackground(String... urls) {
String urldisplay = urls[0];
Bitmap mIcon11 = null;
try {
InputStream in = new java.net.URL(urldisplay).openStream();
mIcon11 = BitmapFactory.decodeStream(in);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
return mIcon11;
}
In order for the image to be displayed inside the app, use the method below in your onCreate method:
new DownloadImageTask((ImageView) -your imageview id-)
.execute(-your URL-);
In order for the image to be saved INTERNALLY inside the app/phone, use the code below:
#SuppressLint("WrongThread")
protected void onPostExecute(Bitmap result) {
if (result != null) {
File dir = new File(peekAvailableContext().getFilesDir(), "MyImages");
if(!dir.exists()){
dir.mkdir();
}
File destination = new File(dir, "image.jpg");
try {
destination.createNewFile();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
result.compress(Bitmap.CompressFormat.PNG, 0, bos);
byte[] bitmapdata = bos.toByteArray();
FileOutputStream fos = new FileOutputStream(destination);
fos.write(bitmapdata);
fos.flush();
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
bmImage.setImageBitmap(result);
}
}
To load the image from the internal storage, use the code below:
private void loadImageFromStorage(String path)
{
try {
File f=new File(path, "image.jpg");
Bitmap b = BitmapFactory.decodeStream(new FileInputStream(f));
ImageView img=(ImageView)findViewById(R.id.businessCard_iv);
img.setImageBitmap(b);
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
}
Things to note: 1. path is the a string containing the path of the file. 2. "image.jpg" is the file name so ensure that matches with yours. 3. "MyImages" is a folder in your path which contains the actual saved image.
I'm trying to use WallpaperManager in a ViewPager. I've got a button which is supposed to set the current image in the ViewPager to wallpaper. My problem comes with the line of code wallpManager.setResource(newInt);... the integer it comes up with is always 0 (zero), and so the app crashes and LogCat says there's no Resource at ID #0x0. As a test to see if I'm getting the correct image URL I've done this:
String newStr = images[position];
CharSequence cs = newStr;
Toast.makeText(UILPager.this, cs, Toast.LENGTH_SHORT).show();
And the resulting Toast shows the correct image URL. I can't figure out how to convert the URL which is in the form of "http://www.example.com/image.jpg" to an Integer so that the WallpaperManager can use it. Here's what the whole button code looks like:
wallp_BTN.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
WallpaperManager wallpManager = WallpaperManager.getInstance(getApplicationContext());
String newStr = images[position];
int newInt = 0;
try{
newInt = Integer.parseInt(newStr);
} catch(NumberFormatException nfe) {
}
CharSequence cs = newStr;
try {
wallpManager.setResource(newInt);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Toast.makeText(UILPager.this, cs, Toast.LENGTH_SHORT).show();
}
});
Set wallpaper from URL
try {
URL url = new URL("http://developer.android.com/assets/images/dac_logo.png");
Bitmap bitmap = BitmapFactory.decodeStream(url.openStream());
wallpaperManager.setBitmap(bitmap);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Enjoy =)
A method wallpaperManager.setResource() requires resource id from your application. Example: I've ImageView with id "myImage" then call the method will look like as wallpaperManager.setResource(R.id.myImage).
In your case your id not valid.
Instead of wallpManager.setResource(0) you should use the wallpManager.setResource(R.drawable.yourimage) since it's expecting a drawable and there is none in your app with id = 0.
In your code
String newStr = images[position];
int newInt = 0;
try{
newInt = Integer.parseInt(newStr);
} catch(NumberFormatException nfe) {
}
Since newStr is never a number, always a url so NumberFormatException is caught always. Hence the value of newInt is always initialized to 0. Hence the error.
I realized that I have to download the image before I can set it as wallpaper! Thanks for your help AndroidWarrior and Owl. When I get the download code worked out, I'll post it. Owl showed me how to download the wallpaper:
//--- Wallpaper button
wallp_BTN.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
try {
vpURL = new URL(images[position]);
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
WallpaperManager wallpManager = WallpaperManager.getInstance(getApplicationContext());
try {
Bitmap bitmap = BitmapFactory.decodeStream(vpURL.openStream());
wallpManager.setBitmap(bitmap);
Toast.makeText(UILPager.this, "The wallpaper has been set!", Toast.LENGTH_LONG).show();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
//--- END Wallpaper button
... and I also figured out how to download the ViewPager image as well (I need to do both in different areas of my app):
//--- Wallpaper button
wallp_BTN.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
String vpURLStr = images[position];
GetVPImageTask downloadVPImageTask = new GetVPImageTask();
downloadVPImageTask.execute(new String[] { vpURLStr });
}
});
//--- END Wallpaper button
//--- Download ViewPager Image AsyncTask
private class GetVPImageTask extends AsyncTask<String, Void, Bitmap> {
ProgressDialog getVPImageDia;
#Override
protected void onPreExecute() {
super.onPreExecute();
getVPImageDia = new ProgressDialog(UILNPPager.this);
getVPImageDia.setMessage("Grabbing the image...");
getVPImageDia.setIndeterminate(false);
getVPImageDia.show();
}
#Override
protected Bitmap doInBackground(String... urls) {
Bitmap map = null;
for (String url : urls) {
map = downloadImage(url);
}
return map;
}
// Sets the Bitmap returned by doInBackground
#Override
protected void onPostExecute(Bitmap result) {
try {
getVPImageDia.dismiss();
getVPImageDia = null;
} catch (Exception e) {
// nothing
}
Toast.makeText(UILNPPager.this, "The image be Downloaded!", Toast.LENGTH_SHORT).show();
//downloaded_iv.setImageBitmap(result);
}
// Creates Bitmap from InputStream and returns it
private Bitmap downloadImage(String url) {
Bitmap bitmap = null;
InputStream stream = null;
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inSampleSize = 1;
try {
stream = getHttpConnection(url);
bitmap = BitmapFactory.
decodeStream(stream, null, bmOptions);
stream.close();
} catch (IOException e1) {
e1.printStackTrace();
}
return bitmap;
}
// Makes HttpURLConnection and returns InputStream
private InputStream getHttpConnection(String urlString)
throws IOException {
InputStream stream = null;
URL url = new URL(urlString);
URLConnection connection = url.openConnection();
try {
HttpURLConnection httpConnection = (HttpURLConnection) connection;
httpConnection.setRequestMethod("GET");
httpConnection.connect();
if (httpConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
stream = httpConnection.getInputStream();
}
} catch (Exception ex) {
ex.printStackTrace();
}
return stream;
}
}
//--- END Download ViewPager Image AsyncTask
I'm having some troubles displaying an image I am fetching from a URL into an ImageView. With the code I have at the moment, I am getting absolutely nothing. Is there a problem with this code?
Drawable img = image.LoadImageFromWeb(icon);
imageView.setImageDrawable(img);
public static Drawable LoadImageFromWeb(String iconId) {
try {
String url = "http://ddragon.leagueoflegends.com/cdn/4.3.12/img/profileicon/" + iconId + ".png";
InputStream is = (InputStream) new URL(url).getContent();
Drawable icon = Drawable.createFromStream(is, "src name");
return icon;
} catch (Exception e) {
return null;
}
}
try this function
private void downloadImage()
{
Bitmap bitmap = null;
try {
URL urlImage = new
URL("http://ddragon.leagueoflegends.com/cdn/4.3.12/img/profileicon/" + iconId +
".png");
HttpURLConnection connection = (HttpURLConnection)
urlImage.openConnection();
InputStream inputStream = connection.getInputStream();
//****bitmap is your image*****
bitmap = BitmapFactory.decodeStream(inputStream);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
and use asyncTask to wait until downloading the image like this
private class Asyn_SaveData extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... params) {
//get the random string from prefs
if (context != null)
downloadImage();
return null;
}
#Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
//do what you want after the image downloaded
}
}
Note: AsyncTask must be subClassed, and after the doInBackground finish its job it calls automatically the onPostExecute

Currently I'm trying to download an image which is stored in my server directory. But I don't know why my app still display that image even though that image is replace with another image.
Meaning that firstly I upload image1, then I can load image1. when image1 is replace by image2, the app still show image1.
Im not sure where is my error. Does it lies in the code or other reason. Needed some help!
Below is my code:
button1.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
new download().execute();
}
});
class download extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... path) {
String outPut = null;
String s = "http://url/image/img_123.jpg";
URL myFileUrl = null;
try {
myFileUrl = new URL(s);
} catch (MalformedURLException e) {
e.printStackTrace();
}
try {
HttpURLConnection conn = (HttpURLConnection) 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();
bm = BitmapFactory.decodeStream(is);
outPut = "success";
} catch (IOException e) {
e.printStackTrace();
}
return outPut;
}
protected void onPostExecute(String file_url) {
// updating UI from Background Thread
runOnUiThread(new Runnable() {
public void run() {
imageView1.setImageBitmap(bm);
}
});
}
}
UPDATE
button1.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// new download().execute();
Drawable drawable = LoadImageFromWeb("http://url/image/img_123.jpg");
imageView1.setImageDrawable(drawable);
}
});
private Drawable LoadImageFromWeb(String url) {
try {
InputStream is = (InputStream) new URL(url).getContent();
Drawable d = Drawable.createFromStream(is, "src name");
return d;
} catch (Exception e) {
System.out.println("Exc="+e);
return null;
}
}
Here is one example which help to download image file from URL and it store your custom location, by which you can display on screen after download
http://getablogger.blogspot.in/2008/01/android-download-image-from-server-and.html
Update:
I think you need to load image direcly from url..see here
