I am working on project where I have to download attachments that i receive from server. I have to exploit base64 data and convert it to the appropriate type and download it. It works for me perfectly with images ( base 64 => bytes => bitmap ) but I find troubles with other types ( txt , pdf ..etc )

try this

 try 

 File sdcard = Environment.getExternalStorageDirectory();
 File file = new File(sdcard,"test.pdf");

 File new_file_name = new File(sdcard,"new_file.pdf");

 byte input_file = IOUtil.readFile(file);


 byte encodedBytes = Base64.encode(input_file,URL_SAFE);
 String encodedString = new String(encodedBytes);
 byte decodedBytes = Base64.decode(encodedString.getBytes(),URL_SAFE);

 FileOutputStream fos = new FileOutputStream(new_file_name);
 fos.write(decodedBytes);
 fos.flush();
 fos.close();
 catch (Exception e)
 
 Log.e("ERROR",e.toString());
 

And IOUtil class

public class IOUtil 

 public static byte readFile(String file) throws IOException 
 return readFile(new File(file));
 

 public static byte readFile(File file) throws IOException 
 // Open file
 RandomAccessFile f = new RandomAccessFile(file, "r");
 try 
 // Get and check length
 long longlength = f.length();
 int length = (int) longlength;
 if (length != longlength)
 throw new IOException("File size >= 2 GB");
 // Read file and return data
 byte data = new byte[length];
 f.readFully(data);
 return data;
 finally 
 f.close();
 
 

this code contain both encode and decode parts
