video download from google+/picasa android

We have a requirement to download video from google+/picasa and store it into sdcard.
Can you please any one help me to solve this issue?
google+/picasa
Converting from URI to byte[], then byte[] is stored to file:
InputStream videoStream = getActivity().getContentResolver().openInputStream(videoUri);
byte bytes[] = ByteStreams.toByteArray(videoStream );
videoFile = new File("abcd.mp4");
FileOutputStream out = new FileOutputStream(videoFile);
out.write(bytes);
out.close();

Can you try that one :
public String DownloadFromUrl(String DownloadUrl, String fileName) {
File SDCardRoot = null;
try {
SDCardRoot = Environment.getExternalStorageDirectory();
File files = new File(SDCardRoot+fileName);
int sizeoffile;
if(!files.exists())
{
File root = android.os.Environment.getExternalStorageDirectory();
File dir = new File (root.getAbsolutePath());
if(dir.exists()==false) {
dir.mkdirs();
}
URL url = new URL(DownloadUrl);
File file = new File(dir, fileName);
/* Open a connection to that URL. */
URLConnection ucon = url.openConnection();
sizeoffile = ucon.getContentLength();
Log.d("SIZEOFFILE: ", sizeoffile+" BYTE");
/*
* 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();
}
}
catch (IOException e) {
e.getMessage();
}
return SDCardRoot+fileName; }

Finally i found the solution.
Uri videoUri = data.getData();
File videoFile = null;
final InputStream imageStream;
try {
imageStream = getActivity().getContentResolver().openInputStream(videoUri);
byte bytes[] = ByteStreams.toByteArray(imageStream);//IStoByteArray(imageStream);
videoFile = new File(Environment.getExternalStorageDirectory()+ "/"+System.currentTimeMillis()+".mp4");
videoFile.createNewFile();
FileOutputStream out = new FileOutputStream(videoFile);
out.write(bytes);
out.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
}catch (Exception ee){
ee.printStackTrace();
}

I have recently encountered this.
I first discovered that what I'm receiving is a picture rather than a video.
But I didn't understand why Facebook is successfully playing the online video I shared via (Google+'s) Photo.
I then occasionally discovered that the file they're currently giving is a GIF with the original extension in the MediaStore.Images.Media.DISPLAY_NAME section of the contentUri.
Eeek!

How to download file in Android over HTTPs

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();

save image in android

This is a code for saving images in SD card if and if not exist.
but i don't know how to read it.
Can anybody help me please.
This is the download file method:
public static String DownLoadFile(String netUrl, String name ) {
try {
//need uses permission WRITE_EXTERNAL_STORAGE
ByteArrayBuffer baf = null;
long startTime = 0;
//get to directory (a File object) from SD Card
File savePath=new File(Environment.getExternalStorageDirectory().getPath()+"/postImages/");
String ext="jpg";
URL url = new URL(netUrl);
//create your specific file for image storage:
File file = new File(savePath, name + "." + ext);
boolean success = true;
if (!savePath.exists()) {
success = savePath.mkdir();
}
if (success) {
if(file.createNewFile())
{
file.createNewFile();
//write the Bitmap
Log.i("file existence", "file does not exist!!!!!!!!!!!");
/* Open a connection to that URL. */
URLConnection ucon = url.openConnection();
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
startTime = System.currentTimeMillis();
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("DownloadManager", "download ready in" + ((System.currentTimeMillis() - startTime) / 1000) + " sec");
return file.getAbsolutePath();
}//end of create file if not exists
}//end of if success
} catch (Exception exx) {
if (exx.getMessage() != null) {
} else {
}
}
return null;
}

Try this,
Uri uri = Uri.parse("file:///sdcard/temporary_file.jpg");
img.setImageURI(uri);

if u have image uri so get path from uri like
String Path = fileUri.getPath();
// read file from sdcard
public static byte[] readFromStream(String path) throws Exception { File
file = new File(path); InputStream inputStream = new
FileInputStream(file); ByteArrayOutputStream baos = new
ByteArrayOutputStream(); DataOutputStream dos = new
DataOutputStream(baos); byte[] data = new byte[(int) file.length()]; int
count = inputStream.read(data); while (count != -1) { dos.write(data, 0,
count); count = inputStream.read(data); } return baos.toByteArray(); }

Save image from url to sdcard

I am saving image from url to sdcard. But image size is 0 in sdcard. Image is created in sdcard but now retrieve data from url and save. so it is giving me 0 size.
try
{
URL url = new URL("http://api.androidhive.info/images/sample.jpg");
InputStream input = url.openStream();
try {
//The sdcard directory e.g. '/sdcard' can be used directly, or
//more safely abstracted with getExternalStorageDirectory()
File storagePath = Environment.getExternalStorageDirectory();
OutputStream output = new FileOutputStream (new File(storagePath,username+".png"));
try {
byte[] buffer = new byte[2048];
int bytesRead = 0;
while ((bytesRead = input.read(buffer, 0, buffer.length)) >= 0) {
output.write(buffer, 0, bytesRead);
}
} finally {
output.close();
}
} finally {
input.close();
}
} catch(Exception e)
{
System.out.println("error in sd card "+e.toString());
}

Try this code.It works...
You should have permission of internet and write external storage.
try
{
URL url = new URL("Enter the URL to be downloaded");
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
urlConnection.connect();
File SDCardRoot = Environment.getExternalStorageDirectory().getAbsoluteFile();
String filename="downloadedFile.png";
Log.i("Local filename:",""+filename);
File file = new File(SDCardRoot,filename);
if(file.createNewFile())
{
file.createNewFile();
}
FileOutputStream fileOutput = new FileOutputStream(file);
InputStream inputStream = urlConnection.getInputStream();
int totalSize = urlConnection.getContentLength();
int downloadedSize = 0;
byte[] buffer = new byte[1024];
int bufferLength = 0;
while ( (bufferLength = inputStream.read(buffer)) > 0 )
{
fileOutput.write(buffer, 0, bufferLength);
downloadedSize += bufferLength;
Log.i("Progress:","downloadedSize:"+downloadedSize+"totalSize:"+ totalSize) ;
}
fileOutput.close();
if(downloadedSize==totalSize) filepath=file.getPath();
}
catch (MalformedURLException e)
{
e.printStackTrace();
}
catch (IOException e)
{
filepath=null;
e.printStackTrace();
}
Log.i("filepath:"," "+filepath) ;
return filepath;

Try this, this may late but it will help someone.
private class ImageDownloadAndSave extends AsyncTask<String, Void, Bitmap>
{
#Override
protected Bitmap doInBackground(String... arg0)
{
downloadImagesToSdCard("","");
return null;
}
private void downloadImagesToSdCard(String downloadUrl,String imageName)
{
try
{
URL url = new URL(img_URL);
/* making a directory in sdcard */
String sdCard=Environment.getExternalStorageDirectory().toString();
File myDir = new File(sdCard,"test.jpg");
/* if specified not exist create new */
if(!myDir.exists())
{
myDir.mkdir();
Log.v("", "inside mkdir");
}
/* checks the file and if it already exist delete */
String fname = imageName;
File file = new File (myDir, fname);
if (file.exists ())
file.delete ();
/* Open a connection */
URLConnection ucon = url.openConnection();
InputStream inputStream = null;
HttpURLConnection httpConn = (HttpURLConnection)ucon;
httpConn.setRequestMethod("GET");
httpConn.connect();
if (httpConn.getResponseCode() == HttpURLConnection.HTTP_OK)
{
inputStream = httpConn.getInputStream();
}
FileOutputStream fos = new FileOutputStream(file);
int totalSize = httpConn.getContentLength();
int downloadedSize = 0;
byte[] buffer = new byte[1024];
int bufferLength = 0;
while ( (bufferLength = inputStream.read(buffer)) >0 )
{
fos.write(buffer, 0, bufferLength);
downloadedSize += bufferLength;
Log.i("Progress:","downloadedSize:"+downloadedSize+"totalSize:"+ totalSize) ;
}
fos.close();
Log.d("test", "Image Saved in sdcard..");
}
catch(IOException io)
{
io.printStackTrace();
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
Declare your network operations in AsyncTask as it will load it as a background task. Don't load network operation on main thread. After this either in button click or in content view call this class like
new ImageDownloadAndSave().execute("");
And don't forget to add the nework permission as:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
Hope this will help :-)

Download image(SSL) and store it on SDcard in Android?

I need to download a single image at time from the Internet and then save it on the SD card. How do I do it? I have made an attempt, but when I try to view that downloaded image, it shows the message, "No Preview Available". Please see my code below:
public class ImgDownloader {
private static final int IO_BUFFER_SIZE = 4 * 1024;
public static final byte[] downloadImage(String imgURL) {
byte[] data = null;
try {
Log.v("Down", "1");
InputStream in = null;
BufferedOutputStream out = null;
in = new BufferedInputStream(new URL(imgURL).openStream(), 8 * 1024);
Log.v("Down", "2");
final ByteArrayOutputStream dataStream = new ByteArrayOutputStream();
out = new BufferedOutputStream(dataStream, IO_BUFFER_SIZE);
copy(in, out);
out.flush();
Log.v("Down", "3");
data = dataStream.toByteArray();
// bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
Log.v("Down", "4");
} catch (Exception ex) {
ex.printStackTrace();
// System.out.println("Exception in Image Downloader .."
// +ex.getMessage());
}
return data;
}
private static void copy(InputStream in, OutputStream out)
throws IOException {
byte[] b = new byte[IO_BUFFER_SIZE];
int read;
while ((read = in.read(b)) != -1) {
out.write(b, 0, read);
}
}
}
Note:
i have download the image from the SSL connection.
Any ideas? Thanks in advance.

You can try something like
try{
URL url = new URL(downloadUrl); //you can write here any link
File file = new File(absolutePath); //Something like ("/sdcard/file.mp3")
//Create parent directory if it doesn't exists
if(!new File(file.getParent()).exists())
{
System.out.println("Path is created " + new File(file.getParent()).mkdirs());
}
file = new File(absolutePath); //Something like ("/sdcard/file.mp3")
file.createNewFile();
/* Open a connection to that URL. */
URLConnection ucon = url.openConnection();
/*
* Define InputStreams to read from the URLConnection.
*/
InputStream is = ucon.getInputStream();
/*
* Read bytes to the Buffer until there is nothing more to read(-1).
*/
FileOutputStream fos = new FileOutputStream(file);
int size = 1024*1024;
byte[] buf = new byte[size];
int byteRead;
while (((byteRead = is.read(buf)) != -1)) {
fos.write(buf, 0, byteRead);
bytesDownloaded += byteRead;
}
/* Convert the Bytes read to a String. */
fos.close();
}catch(IOException io)
{
networkException = true;
continueRestore = false;
}
catch(Exception e)
{
continueRestore = false;
e.printStackTrace();
}
Make the appropriate changes according to your requirement. I use the same code for downloading files from internet and saving it to SDCard.
Hope it helps !!
