Using the accepted answer here, I am trying to download a xml file:
public void get_flickr(double lat,double lang) {
String flickr_api="https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=";
String flickr_key="key";
String flickr_opt="&format=rest&accuracy=11&content_type=1&privacy_filter=1&geo_context=2";
String urls = flickr_api+flickr_key+"&lat="+lat+"&long="+lang+flickr_opt;
try {
URL url = new URL(urls);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.connect();
File file = new File(getApplicationContext().getFilesDir(), "flickr.xml");
FileOutputStream fOut =new FileOutputStream(file);
InputStream fInp = connection.getInputStream();
int totalSize = connection.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 = fInp.read(buffer)) > 0 ) {
//add the data in the buffer to the file in the file output stream (the file on the sd card
fOut.write(buffer, 0, bufferLength);
//add up the size so we know how much is downloaded
downloadedSize += bufferLength;
}
//close the output stream when done
fOut.close();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
which is giving error:
