Answer 1

Here is what you can use to do that :

InputStream in = getResources().openRawResource(R.raw.myresource);
FileOutputStream out = new FileOutputStream(somePathOnSdCard);
byte[] buff = new byte[1024];
int read = 0;

try {
   while ((read = in.read(buff)) > 0) {
      out.write(buff, 0, read);
   }
} finally {
     in.close();

     out.close();
}

try this method

/**
* @param sourceLocation like this /mnt/sdcard/XXXX/XXXXX/15838e85-066d-4738-a243-76c461cd8b01.jpg
* @param destLocation /mnt/sdcard/XXXX/XXXXX/15838e85-066d-4738-a243-76c461cd8b01.jpg
* @return true if successful copy file and false othrerwise
*  
* set this permissions in your application WRITE_EXTERNAL_STORAGE ,READ_EXTERNAL_STORAGE 
*  
*/
public static boolean copyFile(String sourceLocation, String destLocation) {
    try {
        File sd = Environment.getExternalStorageDirectory();
        if(sd.canWrite()){
            File source=new File(sourceLocation);
            File dest=new File(destLocation);
            if(!dest.exists()){
                dest.createNewFile();
            }
            if(source.exists()){
                InputStream  src=new FileInputStream(source);
                OutputStream dst=new FileOutputStream(dest);
                 // Copy the bits from instream to outstream
                byte[] buf = new byte[1024];
                int len;
                while ((len = src.read(buf)) > 0) {
                    dst.write(buf, 0, len);
                }
                src.close();
                dst.close();
            }
        }
        return true;
    } catch (Exception ex) {
        ex.printStackTrace();
        return false;
    }
