Pass bitmap to the saveImage Method  It will save your bitmap in the name of a saveBitmap  inside created test folder   private void saveImage Bitmap data                        File createFolder   new File Environment getExternalStoragePublicDirectory Environment DIRECTORY PICTURES   test                        if  createFolder exists                        createFolder mkdir                        File saveImage   new File createFolder  saveBitmap jpg                        try                           OutputStream outputStream   new FileOutputStream saveImage                           data compress Bitmap CompressFormat JPEG 100 outputStream                           outputStream flush                            outputStream close                          catch  FileNotFoundException e                            e printStackTrace                          catch  IOException e                            e printStackTrace                                              and use this     saveImage bitmap

just change the extension to  bmp   Do this   ByteArrayOutputStream bytes   new ByteArrayOutputStream     bitmapScaled compress Bitmap CompressFormat PNG  40  bytes      you can create a new file name  test BMP  in sdcard folder  File f   new File Environment getExternalStorageDirectory                             File separator    test bmp     It ll sound that I m just fooling around  but try it once and it ll get saved in BMP format  Cheers

Hi You can write data to bytes and then create a file in sdcard folder with whatever name and extension you want and then write the bytes to that file   This will save bitmap to sdcard   ByteArrayOutputStream bytes   new ByteArrayOutputStream     bitmapScaled compress Bitmap CompressFormat JPEG  40  bytes      you can create a new file name  test jpg  in sdcard folder  File f   new File Environment getExternalStorageDirectory                             File separator    test jpg    f createNewFile      write the bytes in file FileOutputStream fo   new FileOutputStream f   fo write bytes toByteArray         remember close de FileOutput fo close

This answer is an update with a little more consideration for OOM and various other leaks   Assumes you have a directory intended as the destination and a name String already defined       File destination   new File directory getPath     File separatorChar   filename        ByteArrayOutputStream bytes   new ByteArrayOutputStream        source compress Bitmap CompressFormat PNG  100  bytes        FileOutputStream fo   null      try           destination createNewFile             fo   new FileOutputStream destination           fo write bytes toByteArray           catch  IOException e           finally           try               fo close              catch  IOException e
