transfering files android studio - java

I want to transfer files between 2 android mobiles.
This is sender
class BackgroundTask extends AsyncTask<String, Void, String> {
String ipaddress , filepath;
#Override
protected String doInBackground(String... params) {
ipaddress =params[0];
filepath=params[1];
try {
File file = new File(Environment.getExternalStorageDirectory(),filepath);
Socket socket = new Socket(ipaddress,5321);
BufferedOutputStream bos = new BufferedOutputStream(socket.getOutputStream());
DataOutputStream dos = new DataOutputStream(bos);
long length = file.length();
dos.writeLong(length);
String name = file.getName();
dos.writeUTF(name);
FileInputStream fis = new FileInputStream(file);
BufferedInputStream bis = new BufferedInputStream(fis);
int theByte = 0;
while((theByte = bis.read()) != -1) bos.write(theByte);
bis.close();
dos.close();
} catch (IOException e) {
;
}
return null;
}
}
and this is receiver code :
#Override
public void run() {
try {
ss = new ServerSocket(5321);
handler.post(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), "waiting for connecting ..",Toast.LENGTH_LONG).show();
}
});
while (true){
mysocket = ss.accept();
handler.post(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), "connected:" + massage,Toast.LENGTH_LONG).show();
}
});
BufferedInputStream bis = new BufferedInputStream(mysocket.getInputStream());
DataInputStream dis = new DataInputStream(bis);
long fileLength = dis.readLong();
String fileName = dis.readUTF();
String downloadfolderpath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).getPath();
File files = new File(downloadfolderpath + "/" + fileName);
FileOutputStream fos = new FileOutputStream(files);
BufferedOutputStream bos = new BufferedOutputStream(fos);
for(int j = 0; j < fileLength; j++) bos.write(bis.read());
bos.close();
dis.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
AND THIS CODE TO GET FILE PATH (NOT SURE ABOUT THE RESULT OF IT)
Intent.ACTION_GET_CONTENT >>
AND ON ACTIVITY RESULT I GET THIS VALUE
intent.putExtra("filename", data.getData().getPath());
Any help

An asynchronous task runs on a background thread, so you directly access variable dload_all in function doInBackground() that is not thread safe. Maybe you can try:
private void startDownloadall() {
//String fileURL = dload_all;
//fileURL = fileURL.replace(" ", "%20");
new DownloadFileAsync1().execute(dload_all, id_all);

Downloading pdf file and saving to SD card

I want to download and save pdf file to internal storage. Here is code that i am using:
I am calling my method from other class:
new Thread(new Runnable() {
public void run() {
new Main().downloadPdfContent("http://people.opera.com/howcome/2005/ala/sample.pdf");
}
}).start();
Method look like this:
public void downloadPdfContent(String urlToDownload){
URLConnection urlConnection = null;
try{
URL url = new URL(urlToDownload);
//Opening connection of currrent url
urlConnection = url.openConnection();
urlConnection.connect();
//int lenghtOfFile = urlConnection.getContentLength();
String PATH = Environment.getExternalStorageDirectory() + "/1/";
File file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, "test.pdf");
FileOutputStream fos = new FileOutputStream(outputFile);
InputStream is = url.openStream();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = is.read(buffer)) != -1) {
fos.write(buffer, 0, len1);
}
fos.close();
is.close();
System.out.println("--pdf downloaded--ok--"+urlToDownload);
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
I found link of pdf on the web:
http://people.opera.com/howcome/2005/ala/sample.pdf
However i get an exception on this line:
urlConnection.connect();
Exception:
java.net.UnknownHostException: people.opera.com
I can't figure out what's wrong. Maybe someone could take a look.
Thanks.
Put
<uses-permission android:name="android.permission.INTERNET"/>
in your AndroidManifest.xml
Follow following steps :
1) Declare file name
String fileName;
//for image
fileName = "matchfine1.png";
//for pdf
fileName = "samplepdf.pdf";
2) Call method to invoke download process.
startDownload(fileName);
3) Define startDownload method:
//for download file start
private void startDownload(String filename) {
String filedowname = filename;
//for image
String url = "http://farm1.static.flickr.com/114/298125983_0e4bf66782_b.jpg";
//for pdf
String url = "http://people.opera.com/howcome/2005/ala/sample.pdf";
new DownloadFileAsync().execute(url,filedowname);
}
4) For auto loading progressBar:
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DIALOG_DOWNLOAD_PROGRESS:
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage("Downloading file..");
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setCancelable(false);
mProgressDialog.show();
return mProgressDialog;
default:
return null;
}
}
5) Define the download process extending AsyncTask
class DownloadFileAsync extends AsyncTask<String, String, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
showDialog(DIALOG_DOWNLOAD_PROGRESS);
}
#Override
protected String doInBackground(final String... aurl) {
try {
File root = android.os.Environment.getExternalStorageDirectory();
File dir = new File (root.getAbsolutePath() + "/Your_file_save_path/");
if(dir.exists()==false) {
dir.mkdirs();
}
URL url = new URL(aurl[0]);
String filename = aurl[1];
URLConnection conexion = url.openConnection();
conexion.connect();
int lenghtOfFile = conexion.getContentLength();
Log.d("ANDRO_ASYNC", "Lenght of file: " + lenghtOfFile);
InputStream input = new BufferedInputStream(url.openStream());
OutputStream output = new FileOutputStream(dir+"/"+filename);
byte data[] = new byte[1024];
long total = 0;
int count;
while ((count = input.read(data)) != -1) {
total += count;
publishProgress(""+(int)((total*100)/lenghtOfFile));
output.write(data, 0, count);
}
output.flush();
output.close();
input.close();
} catch (Exception e) {}
return null;
}
protected void onProgressUpdate(String... progress) {
Log.d("ANDRO_ASYNC", progress[0]);
mProgressDialog.setProgress(Integer.parseInt(progress[0]));
}
#Override
protected void onPostExecute(String unused) {
dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
}
}
//for download file end
6) Replace "Your_file_save_path" by your file path in dir. and then download and check in the specified location.
I have used the same code and got Network.onThreadException Error. But then after using this piece of code in my oncreate() method, I was able to resolve the issue.
if (android.os.Build.VERSION.SDK_INT > 9)
{
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
