i almost finished my app, im working on menu items now,
The problem is to set a bitmap as wallpaper and save it on sdcard from menu item.
i tried to things, 1st was to create a second intent which was taking -again- same data from previous activity , -I have failed-
2nd was using the same intent -i ve failed-
here is my code.
thank you
public class Fullpic extends Activity {

This should help you write the bitmap file to where you need it to be on the SD card of the device, and done in a thread to keep heavy actions off the main UI Thread. Cheers.

In my program i am downloading a Json array file contating data of notices. Each notice contain an address field from where senders image is to be downloaded. So I run another async task to download the images for each json array object. But only 1st image is downloaded no matter how many element json array has. I even tried executeOnExecutor but only folders were created and no images were downloaded.
The onpostexecute method is as below
#Override
protected void onPostExecute(JSONObject jsonObject) {
// TODO Auto-generated method stub
super.onPostExecute(jsonObject);
try {
if (jsonObject.getString("status").equalsIgnoreCase("true")) {
// refining the notices sent by server
JSONArray jsonArray = jsonObject.optJSONArray("notices");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonArrayChild = jsonArray.getJSONObject(i);
// Retrieving data for each notice item
String name = jsonArrayChild.optString("name");
String heading = jsonArrayChild.optString("heading");
String date = jsonArrayChild.optString("date");
String noticeContent = jsonArrayChild
.optString("content");
imageaddress = jsonArrayChild.optString("image");
imageName = imageaddress.substring(
imageaddress.lastIndexOf("/") + 1,
imageaddress.length());
// first we need to download the image from location
// specified in string imageaddress
new ProcessDownloadNoticeSenderImage()
.execute(imageaddress);
// now inserting the overall data into database
// storing the local address of downloaded image in
// database
File file = new File(
Environment.getExternalStorageDirectory()
+ "/veda/images/" + imageName);
String localImageAddress = file.getAbsolutePath();
// storing data in database
noticeMainDatabase.insertNotice(name, heading, date,
noticeContent, localImageAddress);
// first we need to download the image from location
// specified in string imageaddress
}
}
}
and ProcessDownloadNoticeSenderImage is as below
private class ProcessDownloadNoticeSenderImage extends
AsyncTask<String, Integer, Bitmap> {
Bitmap bitmap = null;
#Override
protected Bitmap doInBackground(String... params) {
// TODO Auto-generated method stub
File folder = new File(Environment.getExternalStorageDirectory()

help me in how to download multiple images so that i can show them in list.
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 {

httpConnection.setRequestMethod("GET");
httpConnection.connect();
if (httpConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
stream = httpConnection.getInputStream();

ex.printStackTrace();
}
return stream;
}

How can declared dynamically multiple images URL and i want to display selected one image not display all images.Images retrieved in Server.
I tried this code only one image is retrieved from server. I need to how declare and retrieve multiple images and this same code can declare images.
The coding is as follow,..
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
class Image_Async extends AsyncTask<Bitmap,Bitmap,Bitmap>
{
#Override
protected Bitmap doInBackground(Bitmap... arg0) {
// TODO Auto-generated method stub
Bitmap bmp= null;
try {
URL url =
new URL("http://fc02.deviantart.net/fs42/i/2009/132/7/2/DIWA_boy_animation_by_LunarRain27.jpg");
try {
bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return bmp;
}
Anybody give your suggestion...
Create an array of URL string and Bitmap..
And process them one by one adding the result if the InputStream to the Bitmap array on each URL..
The problem..
Lets say you have a lot of URL with BitMaps it may result to OutOfMemoryException
Hmmm, I'm not sure what you are asking for exactly.
If you want to be able to cache images (download many and display one at a time) use Universal Image Loader
https://github.com/nostra13/Android-Universal-Image-Loader
If you are just looking for a way to download multiple images, then instead of decoding the bitmap, open the input stream and write to a file.
try {
final File file = new File(getCacheDir(), "imagename goes here");
final OutputStream output = new FileOutputStream(file);
try {
try {
final byte[] buffer = new byte[1024];
int read;
// this is the input stream from your url connection
while ((read = inputstream.read(buffer)) != -1)
output.write(buffer, 0, read);
output.flush();
} finally {
output.close();
}
} catch (Exception e) {
e.printStackTrace();
}
} finally {
inputstream.close();
}
as you are not going to want to have that many images in RAM for no reason. (but maybe you do have a reason?
public static Bitmap getBitmapFromURL(String src) {
try {
URL url = new URL(src);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
Bitmap myBitmap = BitmapFactory.decodeStream(input);
return myBitmap;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
anyways, you run one of the above in a loop for as many images as you have, on a background thread, have it notify you when it is done. example
class EZAsyncTask extends AsyncTask<Void, Void, List<Bitmap>>
{
private AsyncTaskListener listener;
private List<String> urlList;
public EZAsyncTask(List<String> urlList, AsyncTaskListener listener)
{
super();
this.urlList = urlList;
this.listener = listener;
}
#Override
protected String doInBackground(Void... params)
{
List<Bitmap> bitmapList = new ArrayList<Bitmap>();
for (String url : urlList)
{
bitmapList.add(getBitmapFromURL(url));
}
return bitmapList;
}
#Override
protected void onPostExecute(List<Bitmap> bitmapList)
{
super.onPostExecute(bitmapList);
listener.onCompletion(bitmapList);
}
public interface AsyncTaskListener
{
public void onCompletion(List<Bitmap> bitmapList);
}
}
and use it like this
urlList = new ArrayList<String>();
urlList.add("http://images.fastcompany.com/upload/Simple.jpg");
EZAsyncTask ezTask = new EZAsyncTask(urlList, new AsyncTaskListener() {
#Override
public void onCompletion(List<Bitmap> bitmapList)
{
// TODO handle response
}
});
ezTask.execute();
Anyways there is a lot there. Try to understand it all if you can, it will help greatly in the long run ;)
How do you implement Progress Download Dialog based on the codes below? My codes downloads images from a specific URL then it saves the image file into SD Card and set the image as wallpaper. I want to show a Progress Download Dialog when the user touches the options menu button setwallpaper().
public boolean onOptionsItemSelected(MenuItem item) {

Bitmap bmImg = null;
try {
HttpURLConnection conn = (HttpURLConnection) myFileUrl.openConnection();
conn.setDoInput(true);
conn.connect();
//int length = conn.getContentLength();
InputStream is = conn.getInputStream();
bmImg = BitmapFactory.decodeStream(is);
}
catch (IOException e)
{
e.printStackTrace();
}
try {
String path = myFileUrl.getPath();
String idStr = path.substring(path.lastIndexOf('/') + 1);
File filepath = Environment.getExternalStorageDirectory();
File dir = new File (filepath.getAbsolutePath() + "/Wallpaper/");
dir.mkdirs();
String fileName = idStr;
File file = new File(dir, fileName);
FileOutputStream fos = new FileOutputStream(file);
bmImg.compress(CompressFormat.JPEG, 75, fos);
fos.flush();
fos.close();
WallpaperManager wpm = WallpaperManager.getInstance(getBaseContext());
wpm.setBitmap(bmImg);
}
catch (Exception e){
e.printStackTrace();

Here you can use the AsyncTask for the show the progressbar/dialogbox .
Show the progress bar visible inside the onPreExecute() method. And performs the image loading operations inside the doInBackground() method. Once this operation is done, we will make progress bar invisible and make imageview visible with that loaded image inside the onPostExecute() method.
For more information check this LINK
Try using this
final ProgressDialog dialog = ProgressDialog.show(
YourACtivity.this, "", "Loading...please wait");
new Thread(new Runnable() {
#Override
public void run() {
SetWallpaper(image_url);
if (dialog != null && dialog.isShowing()) {
dialog.dismiss();
}
}
}).start();
}
instead of
SetWallpaper(image_url);
in the onOptionsItemSelected(MenuItem item)
and next use Handlers to handle http://developer.android.com/reference/android/os/Handler.html

You need to use the MODE_APPEND flag in openFileOutput, otherwise the old file contents gets overwritten by default.
