This is the code itself. He borrowed borrowedly from Habr.

ImageView imageView; // ImageView, содержащий изображение, которое нужно сохранить String folderToSave = Environment.getExternalStorageDirectory().toString(); // папка куда сохранять, в данном случае - корень SD-карты private String SavePicture(ImageView iv, String folderToSave) { OutputStream fOut = null; Time time = new Time(); time.setToNow(); try { File file = new File(folderToSave, Integer.toString(time.year) + Integer.toString(time.month) + Integer.toString(time.monthDay) + Integer.toString(time.hour) + Integer.toString(time.minute) + Integer.toString(time.second) +".jpg"); // создать уникальное имя для файла основываясь на дате сохранения fOut = new FileOutputStream(file); Bitmap bitmap = (BitmapDrawable) iv.getDrawable().getBitmap(); bitmap.compress(Bitmap.CompressFormat.JPEG, 85, fOut); // сохранять картинку в jpeg-формате с 85% сжатия. fOut.flush(); fOut.close(); MediaStore.Images.Media.insertImage(getContentResolver(), file.getAbsolutePath(), file.getName(), file.getName()); // регистрация в фотоальбоме } catch (Exception e) // здесь необходим блок отслеживания реальных ошибок и исключений, общий Exception приведен в качестве примера { return e.getMessage(); } return ""; }

The question is actually that this design does not work, what could be the problem? After clicking the Save button, nothing happens.

 public void btnSave_Click(View v){ SavePicture(imageView,folderToSave); }

Maybe I'm doing something wrong?

    You have a crash somewhere, the author of the code carefully wrote about the need for honest catching in the commentary. Try this:

     public void btnSave_Click(View v) { Toast.makeText(SavePicture(imageView, folderToSave)).show(); }

    And see what the message will show after the click. Most likely, it will be IOEcxeption.
