Getting bitmap as null

I am trying to download the image from url and save it in a file. But it's not getting saved. So as I debug the code I found that bitmap is always null.
code:
public class ImageUserTask extends AsyncTask<Void, Void,String> {
String strURL, imageprofile;
Bitmap mBitmap = null;
Context mContext;
private File profileFile;
public ImageUserTask(Context context, String url) {
this.strURL = url;
this.imageprofile = imageprofile;
this.mContext = context;
}
#Override
protected String doInBackground(Void... params) {
Bitmap bitmap = null;
File directory = null;
try {
URL url = new URL(strURL);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
// InputStream input = connection.getInputStream();
bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream()); //This bitmap is null always
directory = Environment.getExternalStorageDirectory();
// Create a new folder in SD Card
File dir = new File(Environment.getExternalStorageDirectory().getPath() + "/Profile");
if (!directory.exists() && !directory.isDirectory()) {
directory.mkdirs();
}
File mypath = new File(dir,"ProfileImage");
saveFile(mypath, bitmap);
} catch (MalformedURLException e) {
} catch (IOException e) {
}
return directory.getAbsolutePath();
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (result != null) {
imageprofile = result;
}
}
private void saveFile(File fileName, Bitmap bmp) {
FileOutputStream outputStream = null;
try {
outputStream = new FileOutputStream(fileName);
bmp.compress(Bitmap.CompressFormat.JPEG, 100, outputStream); // 100 will be ignored
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (outputStream != null) {
outputStream.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
EDIT:
public class ImageUserTask extends AsyncTask<Void,Void,Bitmap> {
String strURL, imageprofile;
Bitmap mBitmap = null;
Context mContext;
private File profileFile;
public ImageUserTask(Context context, String url) {
this.strURL = url;
this.imageprofile = imageprofile;
this.mContext = context;
}
#Override
protected Bitmap doInBackground(Void... params) {
getImageFromUrl(strURL);
return mBitmap;
}
#Override

super.onPostExecute(result);
if (result != null) {
Bitmap bitmap = result;
}
}
public Bitmap getImageFromUrl(String urlString) {
try {

try {
if(mBitmap!=null) {
mBitmap.recycle();
mBitmap=null;
}
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setDoInput(true);
//Connected to server
connection.connect();
//downloading image
InputStream input = connection.getInputStream();
mBitmap = BitmapFactory.decodeStream(input);
convertBitmapToFile(mBitmap, urlString);
} catch (IOException e) {
e.printStackTrace();
}
} catch (MalformedURLException e) {
e.printStackTrace();
}
return mBitmap;
}
public File convertBitmapToFile(Bitmap bitmap, String fileName) {
ContextWrapper cw = new ContextWrapper(mContext);
File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
File mypath = new File(directory, fileName);
FileOutputStream fos = null;
try {
fos = new FileOutputStream(mypath);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
return mypath;
}
}
What can be the reason? I have added Internet permissions too. Please help. Thank you..

This code is work for me

Use the below methods
public Bitmap getImageFromUrl(String urlString) {
Bitmap bmp = null;
try {
URL url = new URL(urlString);
try {
if(bmp!=null) {
bmp.recycle();
bmp=null;
}
bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
convertBitmapToFile(bmp, urlString);
} catch (IOException e) {
e.printStackTrace();
}
} catch (MalformedURLException e) {
e.printStackTrace();
}
return bmp;
}
public File convertBitmapToFile(Bitmap bitmap, String fileName) {
ContextWrapper cw = new ContextWrapper(activityRef.getApplicationContext());
File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
File mypath = new File(directory, fileName);
FileOutputStream fos = null;
try {
fos = new FileOutputStream(mypath);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
return mypath;
}
Add android Permissions for internet and Storage

Please try this
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;
}
}

Download a large pdf with jsoup

I would like to download a large pdf file with jsoup. I have try to change timeout and maxBodySize but the largest file I could download was about 11MB. I think if there is any way to do something like buffering. Below is my code.
public class Download extends Activity {
static public String nextPage;
static public Response file;
static public Connection.Response res;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
Bundle b = new Bundle();
b = getIntent().getExtras();
nextPage = b.getString("key");
new Login().execute();
finish();
}
private class Login extends AsyncTask<Void, Void, Void> {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected Void doInBackground(Void... params) {
try {
res = Jsoup.connect("http://www.eclass.teikal.gr/eclass2/")
.ignoreContentType(true).userAgent("Mozilla/5.0")
.execute();
SharedPreferences pref = getSharedPreferences(
MainActivity.PREFS_NAME, MODE_PRIVATE);
String username1 = pref.getString(MainActivity.PREF_USERNAME,
null);
String password1 = pref.getString(MainActivity.PREF_PASSWORD,
null);
file = (Response) Jsoup
.connect("http://www.eclass.teikal.gr/eclass2/")
.ignoreContentType(true).userAgent("Mozilla/5.0")
.maxBodySize(1024*1024*10*2)
.timeout(70000*10)
.cookies(res.cookies()).data("uname", username1)
.data("pass", password1).data("next", nextPage)
.data("submit", "").method(Method.POST).execute();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Void result) {
String PATH = Environment.getExternalStorageDirectory()
+ "/download/";
String name = "eclassTest.pdf";
FileOutputStream out;
try {
int len = file.bodyAsBytes().length;
out = new FileOutputStream(new File(PATH + name));
out.write(file.bodyAsBytes(),0,len);
out.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
I hope somebody could help me!

I think, it's better to download any binary file via HTTPConnection:
InputStream input = null;
OutputStream output = null;
HttpURLConnection connection = null;
try {
URL url = new URL("http://example.com/file.pdf");
connection = (HttpURLConnection) url.openConnection();
connection.connect();
// expect HTTP 200 OK, so we don't mistakenly save error report
// instead of the file
if (connection.getResponseCode() != HttpURLConnection.HTTP_OK) {
return "Server returned HTTP " + connection.getResponseCode()
+ " " + connection.getResponseMessage();
}
// this will be useful to display download percentage
// might be -1: server did not report the length
int fileLength = connection.getContentLength();
// download the file
input = connection.getInputStream();
output = new FileOutputStream("/sdcard/file_name.extension");
byte data[] = new byte[4096];
int count;
while ((count = input.read(data)) != -1) {
output.write(data, 0, count);
}
} catch (Exception e) {
return e.toString();
} finally {
try {
if (output != null)
output.close();
if (input != null)
input.close();
} catch (IOException ignored) {
}
if (connection != null)
connection.disconnect();
}
Jsoup is for parsing and loading HTML pages, not binary files.

here before ImageDownload is start executing before test async task is complete
and i am not able to get the status of the task can u tell how it is done

whatever i understood from this you want to execute your ImageDownload thread after the task thread,so start the ImageDownload Thread from the onPostExecute() of your task thread

When executing an async task a new thread is started, but your current thread keeps running. It immediately runs into your thread.sleep(1000) just after starting test.async.
It looks like your doing some internet downloading in test.async, and as you might have guessed, it takes longer than 1000 milliseconds (1 second). This means 1 second later, your other async is starting, before the first completed.
I assume you want to stagger them. In the postExecute of the first async, you can spawn the second async. A more stylistically correct method would be to implement an interface on your activity that takes a callback on Async completion, then upon receiving the call back, launch your second async.
An example of how to structure this is below.
interface AsyncCallback{
void onAsyncComplete();
}
public class ExampleActivity extends Activity implements AsyncCallback {
....
public void launchFirstAsync(){
new Task(this).execute();
}
#Override
public void onAsyncComplete() {
//todo launch second asyncTask;
}
}
class Task extends AsyncTask<Void, Void, Void>{
AsyncCallback cb;
Task(AsyncCallback cb){
this.cb = cb;
}
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
return null;
}
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
cb.onAsyncComplete();
}
}

Over time there have been several changes to the way Android deals with AsyncTasks that run concurrently. In very old Android versions (pre-1.6 afaik) multiple AsyncTasks were executed in sequence. That behavior has been changed to run the AsyncTasks in parallel up until Android 2.3. Beginning with Android 3.0 the the Android team decided that people were not careful enough with synchronizing the tasks that run in parallel and switched the default behavior back to sequential execution. Internally the AsyncTask uses an ExecutionService that can be configured to run in sequence (default) or in parallel as required:
ImageLoader imageLoader = new ImageLoader( imageView );
imageLoader.executeOnExecutor( AsyncTask.THREAD_POOL_EXECUTOR, "http://url.com/image.png" );

Error in getting facebook profile picture url android

I want to get user's facebook profile picture url and below is code for that.
Code :
Thread thread = new Thread(new Runnable() {
#Override
public void run() {
StringBuilder res = new StringBuilder();
// fetch user profile picture url
URL url = null;
HttpURLConnection httpconn = null;
String strUrl = "http://graph.facebook.com/"
+ fbuser.getFacebookId()
+ "/picture?width=350&height=350";
try {
url = new URL(strUrl);
httpconn = (HttpURLConnection) url
.openConnection();
} catch (MalformedURLException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
try {
if (httpconn.getResponseCode() == HttpURLConnection.HTTP_OK) {
BufferedReader input = new BufferedReader(
new InputStreamReader(httpconn
.getInputStream()));
String strLine = null;
while ((strLine = input.readLine()) != null) {
res.append(strLine);
}
input.close();
}
Log.e(TAG, "res : " + res);
JSONObject imageUrlObject = new JSONObject(
res.toString());
fbuser.setImageUrl(imageUrlObject
.getJSONObject("picture")
.getJSONObject("data")
.getString("url"));
// Call a method of an Activity to notify
// user info is received
((RS_LoginActivity) RS_Facebook.this.activity)
.FacebookUserInfoReceived();
// call login api
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}
});
thread.start();
I log the string response and below is the screen shot of how that response looks like.
Any idea why this happens?

The API spec likely changed; use the following workaround:
fbuser.setImageUrl("http://graph.facebook.com/"
+ fbuser.getFacebookId()
+ "/picture?width=350&height=350");
That URL is what got you a JPEG image as of lately, so it's likely the URL you need.

This works like a charm, the problem i am having is that the content length from the entitiy is 582504 but when i look into the file manager the size goes upto 863145. I think that some data is being added while writing file to SD Card. Is there any solution to this?

This is my code which works fine, please check if this works for you
public class downloadApk extends AsyncTask<Integer, Integer, Integer>
{
#Override
protected Integer doInBackground(Integer... params) {
// TODO Auto-generated method stub
try {
URL url = new URL("http://www.tagsinfosoft.com/android/shelf/Shelf_Cam.apk");
HttpURLConnection c = (HttpURLConnection) url.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
String PATH = Environment.getExternalStorageDirectory() + "/download/";
File file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, "Shelf_Cam.apk");
FileOutputStream fos = new FileOutputStream(outputFile);
InputStream is = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = is.read(buffer)) != -1) {
fos.write(buffer, 0, len1);
}
fos.close();
is.close();//till here, it works fine - .apk is download to my sdcard in download file
