Save Bitmap into File and return File having bitmap image

private File savebitmap(Bitmap bmp) {
    String extStorageDirectory = Environment.getEx         


        

Answer 1

I try to make some corrections on your code I assume that you want to use filename instead of bitmap as parameter

 private File savebitmap(String filename) {
      String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
      OutputStream outStream = null;

      File file = new File(filename + ".png");
      if (file.exists()) {
         file.delete();
         file = new File(extStorageDirectory, filename + ".png");
         Log.e("file exist", "" + file + ",Bitmap= " + filename);
      }
      try {
         // make a new bitmap from your file
         Bitmap bitmap = BitmapFactory.decodeFile(file.getName());

         outStream = new FileOutputStream(file);
         bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream);
         outStream.flush();
         outStream.close();
      } catch (Exception e) {
         e.printStackTrace();
      }
      Log.e("file", "" + file);
      return file;

   }

Answer 2

You can't write like this

 File file = new File(bmp + ".png");

and this line is also wrong

file = new File(extStorageDirectory, bmp + ".png");

You have to give string value and not bitmap.

 File file = new File(filename + ".png"); 

Answer 3

Change File file = new File(bmp + ".png"); to File file = new File(extStorageDirectory,"bmp.png"); like you did nearly the second time.
