Out of memory Exception when converting video file

I'm converting a Video file to string using Base64 encoding.

try {
    encodedString =Base64.encodeBytes((getBytesFromFile(new File(Description.PATH))),Base64.GZIP);

} catch (IOException e) {
    e.printStackTrace();
}

When i'm converting 60 sec video, I'm getting out of memory exception..

Please let me know how to solve this issue.

Thanks in advance

I think you should use encodeToString instead of encodeBytes().
