if (file == null) {
return null;
}
String base64 = null;
FileInputStream fin = null;
try {
fin = new FileInputStream(file);
byte[] buff = new byte[fin.available()];
fin.read(buff);
base64 = Base64.encode(buff);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {

} finally {
if (fin != null) {
try {
fin.close();
