HI Siji.
Have you tried this aproach?
public void convert(){
ByteArrayInputStream imageStream = new ByteArrayInputStream(data);
Bitmap theImage = BitmapFactory.decodeStream(imageStream);
try {
File file = FotoFolder.getFotoFile("fileName.png");
FileOutputStream out = new FileOutputStream(file);
theImage.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
