Retrieve image files based on image Uri

1. Obtain the image file based on the Contact Image Uri and display it on ImageView. The Code is as follows:

 Uri uri = Uri.parse("content://com.android.contacts/display_photo/1"               afd = getContentResolver().openAssetFileDescriptor(uri, "r"         [] buffer =  [16 * 1024         FileInputStream fis =                  FileOutputStream fos =  FileOutputStream( File("sdcard/11212"                  ByteArrayOutputStream temp_byte =                    ((size = fis.read(buffer)) != -1             fos.write(buffer, 0             temp_byte.write(buffer, 0                   image.setImageBitmap(BitmapFactory.decodeByteArray(temp_byte.toByteArray(), 0     }       }       }

As you can see above, uri is the photo_uri field in the view_data view of the contact database. The final id should be adjusted according to the actual situation.

2. Obtain the resource storage path based on mediaURI

 Cursor cur = getContentResolver().query(Uri.parse("content://media/external/images/media/279"), , , ,   (cur !=       ( i = 0; i < cur.getColumnCount(); i++          Log.d("Davds", "name = " +                        Log.d("Davds", "" + cur.getString(cur.getColumnIndex("_data"  }

The value obtained from the filed corresponding to _ data is the file storage path.

The following figure is displayed in the database (images table in the MediaProvider database ):
