我想将图像保存在sqlite中。在这种方法中，我将图像路径转换为字符串。我的问题是如何将其转换为byte []格式。

if (resultCode == RESULT_OK) {
// we need to update the gallery by starting MediaSanner service.
mScanner = new MediaScannerConnection(ImagePreviewActivity.this,new MediaScannerConnection.MediaScannerConnectionClient() {

                        public void onMediaScannerConnected() {
                                mScanner.scanFile(imageUri.getPath(), null );
                        }           

                        public void onScanCompleted(String path, Uri uri) {
                            mScanner.disconnect();
                            if (path.equals(imageUri.getPath())) {
                                 photoPath=imageUri.getPath();
                                        ImagePreviewActivity.this.runOnUiThread(new Runnable() {
                                        public void run() {
                                            capture_photo = (ImageView) findViewById(R.id.caturePhoto);
                                            Bitmap myBitmap = BitmapFactory.decodeFile(photoPath);
                                            capture_photo.setImageBitmap(myBitmap);

                                    }
                                });
                                mScanner.disconnect();
                            }
                        }
                    });
                    mScanner.connect();
