Hi! I'm developing an image editor for android. In the main activity, I get to show all images by viewing the thumbnails to make the process faster. The problem it's that I need to process the image later and I would get the normal image ID (with the original size, which I think is in MediaStore.Images.Media). I can't get the form of the query. The code that I have is the following but I can't obtain the real image ID (in the IDImage variable):
int columnIndex = 0; String[] projection = {MediaStore.Images.Thumbnails._ID, MediaStore.Images.Thumbnails.DATA}; // It is necessary to use EXTERNAL_CONTENT_URI of Thumbnails because it contains the // little image and not the original Cursor cursor = managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, projection, null, null, null); if(cursor != null) { cursor.moveToPosition(position); columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA); String imagePath = cursor.getString(columnIndex); columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID); String _IDThumbnails = cursor.getString(columnIndex); String[] nProjection = {MediaStore.Images.Media._ID, MediaStore.Images.Media.PICASA_ID}; String nSelection = MediaStore.Images.ImageColumns.PICASA_ID + " = " + _IDThumbnails; Cursor nCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, nProjection, nSelection, null, null); nCursor.moveToFirst(); columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID); String _IDImage = cursor.getString(columnIndex); FileInputStream is = null; BufferedInputStream bis = null; try { is = new FileInputStream(new File(imagePath)); bis = new BufferedInputStream(is); // Imagen is a class that I have defined image = new Imagen(BitmapFactory.decodeStream(bis), _IDImage); } catch(Exception e) { } finally { try { if(bis != null) bis.close(); if(is != null) is.close(); cursor.close(); projection = null; } catch(Exception e) { } } } Thank you.
