Android Dev Help: Saving an image from Res/raw or Asset folder to the Sd card
<p>I am trying to save an image (jpg or png) from the res/raw or assets folder to the SD card location (/sdcard/DCIM/).</p>

<p>I have been following a tutorial which can save an image from a URL to the SD card Root, but i have looked everywhere to be able to save from res/raw or asset folder instead, and to a differnet location onthe sd card /sdcard/DCIM/</p>

<p>Here is the code, can anyone show me how to do the above from this?</p>

<pre><code>public class home extends Activity {
    private File file;
     private String imgNumber;
     private Button btnDownload;
     /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main); 
       btnDownload=(Button)findViewById(R.id.btnDownload);

      btnDownload.setOnClickListener(new OnClickListener() {

     public void onClick(View v) {
       btnDownload.setText("Download is in Progress.");
      String savedFilePath=Download("http://www.domain.com/android1.png");
      Toast.makeText(getApplicationContext(), "File is Saved in  "+savedFilePath, 1000).show();
      if(savedFilePath!=null)
      {
        btnDownload.setText("Download Completed.");
      }
     }
    });

    } 
    public String Download(String Url)
    {
    String filepath=null;
    try {
    //set the download URL, a url that points to a file on the internet
    //this is the file to be downloaded
    URL url = new URL(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 = Environment.getExternalStorageDirectory();
    //create a new file, specifying the path, and the filename
    //which we want to save the file as.

    String filename= "download_"+System.currentTimeMillis()+".png";   // you can download to any type of file ex:.jpeg (image) ,.txt(text file),.mp3 (audio file)
    Log.i("Local filename:",""+filename);
    file = new File(SDCardRoot,filename);
    if(file.createNewFile())
    {
    file.createNewFile();
    }

    //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)) &gt; 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;
    //this is where you would do something to report the prgress, like this maybe
    Log.i("Progress:","downloadedSize:"+downloadedSize+"totalSize:"+ totalSize) ;
    btnDownload.setText("download Status:"+downloadedSize+" / "+totalSize);
    }
    //close the output stream when done
    fileOutput.close();
    if(downloadedSize==totalSize) filepath=file.getPath();

    //catch some possible errors...
    } catch (MalformedURLException e) {
    e.printStackTrace();
    } catch (IOException e) {
    filepath=null;

    btnDownload.setText("Internet Connection Failed.\n"+e.getMessage());
    e.printStackTrace();
    }
    Log.i("filepath:"," "+filepath) ; 
    return filepath;

    }

}
