Answer 1

after getting the bitmap do this way

Bitmap new_bmp = Bitmap.createBitmap(bm, 0, 0, linear.getWidth(), linear.getHeight(), matrix, false);

            image.draw(new Canvas(new_bmp));
            String s = Environment.getExternalStorageDirectory().toString();

            linear.setBackgroundColor(Color.BLACK);
            OutputStream outStream = null;
            SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_hhmmss");
            String file_name = sdf.format(new Date())+".PNG";
            File file = new File(s, file_name);
            try {
             outStream = new FileOutputStream(file);
             new_bmp.compress(Bitmap.CompressFormat.PNG, 100, outStream);
             outStream.flush();
             outStream.close();
            } catch (FileNotFoundException e) {
                 e.printStackTrace();
                 Toast.makeText(CaptureImage.this, e.toString(), Toast.LENGTH_LONG).show();
            } catch (IOException e) {
                 e.printStackTrace();
                 Toast.makeText(CaptureImage.this, e.toString(), Toast.LENGTH_LONG).show();
            }
