Notify mediastore to scan a file:
private void scanSingleFile(String filePath) { if (filePath == null) { return; }// broadcast to scan file boolean bmnt = Environment.getExternalStorageDirectory().getPath() .startsWith("/mnt"); bmnt = mDownloadDestination .equalsIgnoreCase(UpDownloadUtils.DOWNLOAD_DEST_SDCARD) ? bmnt : false; File file = new File(bmnt ? ("/mnt" + filePath) : filePath); MediaScannerConnection.scanFile(mContext, new String[] { file.toString() }, null, new MediaScannerConnection.OnScanCompletedListener() { @Override public void onScanCompleted(String path, Uri uri) { ContentResolver cr = mContext.getContentResolver(); long datemodified = 0; long dateadded = 0; Cursor cursor = cr.query(uri, null, null, null, null); if (cursor != null && cursor.moveToFirst()) { datemodified = cursor.getLong(cursor .getColumnIndex(MediaStore.MediaColumns.DATE_MODIFIED)); dateadded = cursor.getLong(cursor .getColumnIndex(MediaStore.MediaColumns.DATE_ADDED)); cursor.close(); } ContentValues values = new ContentValues(); if (datemodified > 0 && String.valueOf(datemodified).length() > 10) { values.put(MediaStore.MediaColumns.DATE_MODIFIED, datemodified / 1000); } if (dateadded > 0 && String.valueOf(dateadded).length() > 13) { values.put(MediaStore.MediaColumns.DATE_ADDED, dateadded / 1000); } if (values.size() > 0) { cr.update(uri, values, null, null); } } }); }
Insert file records into mediastore
ContentValues newValues = new ContentValues(6); String title = FileName.substring(0, pointIndex); newValues.put(MediaStore.Images.Media.TITLE, FileName.substring(0, pointIndex)); newValues.put(MediaStore.Images.Media.DISPLAY_NAME, sourceFile.getName()); newValues.put(MediaStore.Images.Media.DATA, sourceFile.getPath()); newValues.put(MediaStore.Images.Media.DATE_MODIFIED, System.currentTimeMillis() / 1000); newValues.put(MediaStore.Images.Media.SIZE, sourceFile.length()); newValues.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg"); uri = contentResolver.insert( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, newValues);
