Base64 decoding help on the issue

Hello everyone brother for help

I use Base64 decoding a relatively large file in about 1M it

Then I practice

 FileOutputStream outStream = new FileOutputStream (localFile); 
InputStream inputStream = conn.getInputStream (); 
byte [] buffer = new byte [1024]; 
int len ​​= 0; 
byte [] decode = null; 
while ((len = inputStream.read (buffer))! = -1) 
{
decode = Base64.decode (buffer, 0, len, Base64.DEFAULT); 
outStream.write (decode, 0, decode.length); 
} 
inputStream.close (); 
outStream.close (); 

Tip java.lang.IllegalArgumentException Runtime: bad base-64

Help What is the problem Can not Break decoding?
Only whole decoding it? (More files are large, easy to overflow ah)

decode = Base64.decode (buffer, 0, len, Base64.DEFAULT);
outStream.write (decode, 0, decode.length);
No complete reading the stream, there is a problem directly decode,
IO data streams are first read and then decoded

Haha great God is your

Why not read a solution because I want to extract some many such large files

If the entire read the words would come overflowed

You can read a file of a file

a file to a file that you can read

I tried to read one by one to read the full stream decoding

However, when the file is too large are generally processed in the end sixty-seven documents they reported overflow. .

So I just want to be able to decode segments

String string = Base64.encodeToString (bytes, Base64.DEFAULT);
Try it this way it

If it is a large file, you adjust the JVM heap memory,
base64 decoded stream when reading failure is if the solution does not come out.
