I am downloading a file in android which goes via plain HTTP. Now i want this connection to go over HTTPs and then download file, can someone help me in code what changes will i need to do that.
I changed
URLConnection ucon = url.openConnection();
to
//HttpsURLConnection ucon = (HttpsURLConnection) url.openConnection();
but that didn't work.
Code:
private void DownloadFile() {
try {
File root = android.os.Environment
.getExternalStorageDirectory();
File dir = new File(root.getAbsolutePath() + "/File");
if (dir.exists() == false) {
dir.mkdirs();
}
URL url = new URL(DownloadFile); // you can write here any link
File file = new File(dir, fileName);
long startTime = System.currentTimeMillis();
Log.d(LOG_TAG, "download begining");
Log.d(LOG_TAG, "download url:" + url);
Log.d(LOG_TAG, "downloaded file name:" + fileName);
/* Open a connection to that URL. */
URLConnection ucon = url.openConnection();
//HttpsURLConnection ucon = (HttpsURLConnection) url.openConnection();
/*
* Define InputStreams to read from the URLConnection.
*/
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
/*
* Read bytes to the Buffer until there is nothing more to
* read(-1).
*/
ByteArrayBuffer baf = new ByteArrayBuffer(5000);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
/* Convert the Bytes read to a String. */
FileOutputStream fos = new FileOutputStream(file);
fos.write(baf.toByteArray());
fos.flush();
fos.close();
Log.d(LOG_TAG,
"download ready in"
+ ((System.currentTimeMillis() - startTime) / 1000)
+ " sec");
} catch (IOException e) {
Log.d(LOG_TAG, "Error: " + e);
}
}
Try this:
URL url = new URL("some url");
//create the new connection
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
//set up some things on the connection
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
//and connect!
urlConnection.connect();
//set the path where we want to save the file
//in this case, going to save it on the root directory of the
//sd card.
File SDCardRoot = new File("/sdcard/"+"Some Folder Name/");
//create a new file, specifying the path, and the filename
//which we want to save the file as.
File file = new File(SDCardRoot,"some file name");
//this will be used to write the downloaded data into the file we created
FileOutputStream fileOutput = new FileOutputStream(file);
//this will be used in reading the data from the internet
InputStream inputStream = urlConnection.getInputStream();
//this is the total size of the file
int totalSize = urlConnection.getContentLength();
//variable to store total downloaded bytes
int downloadedSize = 0;
//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();
