Download and save PDF on sdcard not found

I'm trying to download a pdf from an url and then save and read it. But I get the error java.io.IOException: /storage/emulated/0/pdf/menu.pdf not found as file or resource. when I try to read it. Any idea ?
Here is my Downloader class :
public class Downloader {
public static void DownloadFile(String fileURL, File directory) {
try {
FileOutputStream f = new FileOutputStream(directory);
URL u = new URL(fileURL);
HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
InputStream in = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = in.read(buffer)) > 0) {
f.write(buffer, 0, len1);
}
f.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
And the line to download and read the pdf :
String extStorageDirectory = Environment.getExternalStorageDirectory().getAbsolutePath()
.toString();
File folder = new File(extStorageDirectory, "pdf");
folder.mkdir();
File file = new File(folder, "menu.pdf");
try {
file.createNewFile();
} catch (IOException e1) {
e1.printStackTrace();
}
Downloader.DownloadFile("http://webdfd.mines-ales.fr/restau/Menu_Semaine.pdf", file);
PdfReader reader = new PdfReader(Environment.getExternalStorageDirectory().getAbsolutePath()+"/pdf/menu.pdf");
Here is the error :

if your target and compile sdk higher than lolipop then you have to add request permission code before download refer this link and read and write external storage permission required

The api isApiSupported return true but SipManager newInstance still return null in Android native Sip

I used Android native Sip api to initialize Sip client.Because I am confused to Sip protocol,I read the android developer document about sip and follow it.When I run my application on Nexus5,it work normally,but when I run it on other device like coolpad, it throw NullPointException from SipManager.The following is my code.For some reason,the username,passwd and domain is private.
public static SipManager manager;
public static SipProfile me;
public static String username;
public static String passwd;
public static void initializeSip(Context context) {
System.out.println("initializeSip");
if (manager == null) {
manager = SipManager.newInstance(context);
}
if (me != null) {
closeLocalProfile();
}
username = SharedPreferences.getLoginInfo().getModel().getVos_phone();
passwd = SharedPreferences.getLoginInfo().getModel().getVos_phone_pwd();
try {
if (!(SipManager.isApiSupported(context) && SipManager.isVoipSupported(context))) {
System.out.println("cannot support");
return;
}
System.out.println("isApiSupported="+SipManager.isApiSupported(context));
System.out.println("SipManager="+SipManager.newInstance(context));
SipProfile.Builder builder = new SipProfile.Builder(username, domain);
builder.setPassword(passwd);
me = builder.build();
manager.open(me);
SipRegistrationListener listener = new SipRegistrationListener() {
#Override
public void onRegistering(String localProfileUri) {
System.out.println("Registering with SIP Server");
}
#Override
public void onRegistrationDone(String localProfileUri, long expiryTime) {
System.out.println("Register success");
}
#Override
public void onRegistrationFailed(String localProfileUri, int errorCode, String errorMessage) {
System.out.println("Registeration failed.Please check Settings.");
System.out.println("errorCode="+errorCode);
System.out.println("errorMessage="+errorMessage);
}
};
manager.setRegistrationListener(me.getUriString(),listener);
manager.register(me,3000,listener);
} catch (ParseException e) {
e.printStackTrace();
} catch (SipException e) {
e.printStackTrace();
}
}
The following is my logcat. Most strangely,I find that the api isApiSupported return true and the SipManager object is not null.I cannot find the reason about it.

You cannot perform network tasks on the main thread because it might block your application in case the network task takes a very long time. You need to run such tasks in the background using AsyncTask instead.
Here's the documentation.

Try using the below code inside your main activity below setContentView(), to avoid the networkOnmainThread exception..
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}

Looks like the error is not of json.
You are trying to call a url from Main Thread which is not allowed from android 4.0
Try using AsynTask or call the url from secondary thread.

Android downloading a file getting a FileNotFoundException

else if (v.getId() == R.id.update) {

try {

//create the new connection
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
//set up some things on the connection

urlConnection.setDoOutput(true);
//and connect!
urlConnection.connect();

//in this case, going to save it on the root directory of the
//sd card.

//create a new file, specifying the path, and the filename
//which we want to save the file as.
File file = new File(SDCardRoot,"test.txt");

//variable to store total downloaded bytes

//create a buffer...
byte[] buffer = new byte[1024];
int bufferLength = 0; //used to store a temporary size of the buffer
//now, read through the input buffer and write the contents to the file
while ( (bufferLength = inputStream.read(buffer)) > 0 )

//add the data in the buffer to the file in the file output stream (the file on the sd card
fileOutput.write(buffer, 0, bufferLength);
//add up the size so we know how much is downloaded
downloadedSize += bufferLength;
int progress=(int)(downloadedSize*100/totalSize);
//this is where you would do something to report the prgress, like this maybe
//updateProgress(downloadedSize, totalSize);
}
//close the output stream when done
fileOutput.close();
} catch (MalformedURLException e1) {

this code keeps coming out with the FileNotFoundException, but the file is there, if you follow the url you can see it.
does it have to be hosted in a specific way? or is it something wrong with the way im getting it
