Android: write bytes to image file on SD Card -

i'm trying create image file on sd-card, building bytes server sending towards me after calling web-service (basically: download file). managed "something" on client-side, , try write bytes file, using:

fileoutputstream fout = null; bufferedoutputstream bos = null;  try {         fout = new fileoutputstream(returnedfile);          bos = new bufferedoutputstream(fout);          bos.write(bytestowrite);  } catch (filenotfoundexception e) {         e.printstacktrace(); }  catch (exception e) {         e.printstacktrace(); } {         try {             if (bos != null) {                 bos.close();                 fout.close();             }         } catch (ioexception e) {             e.printstacktrace();         }     } 

but image file broken (its size > 0kb, broken). ended opening file on computer text editor, , saw of initial file data (before being sent), differs final one. i'm guessing there kind of encoding misstakening or that. appreciate idea of how make work ( download image file web server, , open in on phone). ps. can change or info server configuration, configured friend of mine. ps2. should able not download images, kind of file.

i think it's better encode image base64 in server, example in php can :

$type = pathinfo($path, pathinfo_extension); $data = file_get_contents($path); $base64 = 'data:image/' . $type . ';base64,' . base64_encode($data); 

and in android decode base64 string image file:

fileoutputstream fos = null; try {  if (base64imagedata != null) {     fos = context.openfileoutput("imagename.png", context.mode_private);     byte[] decodedstring = android.util.base64.decode(base64imagedata, android.util.base64.default);     fos.write(decodedstring);      fos.flush();     fos.close();      }  } catch (exception e) {  } {     if (fos != null) {         fos = null;     } }
