//This is the file we are going to download. //Please add your server file location .
URL url = new URL("http://www.mission2win.in/pdf/pdf22.pdf");
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
//set path where to save the file
File SDCardRoot = Environment.getExternalStorageDirectory();
//create a new file to save
File file = new File(SDCardRoot,"pdf22.pdf");
FileOutputStream fileOutput = new FileOutputStream(file);
//stream used for reading the data from the internet
InputStream inputStream = urlConnection.getInputStream();
//create a buffer
byte[] buffer = new byte[124];
int bufferLength = 0;
Verify permission and add this code to give a permission
public static void verifyStoragePermissions(Activity activity) {
// Check if we have write permission
int permission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
if (permission != PackageManager.PERMISSION_GRANTED) {
// We don't have permission so prompt the user
ActivityCompat.requestPermissions(
activity,
PERMISSIONS_STORAGE,
REQUEST_EXTERNAL_STORAGE
);
}
}
Other wise add several permission to Manifest file.
<!-- Permission required for Downloading Files -->

<!-- Permission required for Checking Internet Connection -->
//set path where to save the file
File SDCardRoot = Environment.getExternalStorageDirectory();
//create a new file to save
File file = new File(SDCardRoot,"pdf22.pdf");
FileOutputStream fileOutput = new FileOutputStream(file);
//stream used for reading the data from the internet
InputStream inputStream = urlConnection.getInputStream();
//This is total size of the downloading file totalSize = urlConnection.getContentLength(); runOnUiThread(new Runnable() { @Override public void run() { progressBar.setMax(totalSize); } });
//create a buffer
byte[] buffer = new byte[124];
int bufferLength = 0;
