Resolutionīefore you upload the file, calculate the file's MD5 checksum value as a reference for integrity checks after the upload. Or, the aws s3 command doesn't support a required request parameter. For example, the multipart upload involves multiple servers, or you manually stop a multipart upload and resume it later. Use aws s3api commands, such as aws s3api create-multipart-upload, only when aws s3 commands don't support a specific upload. This is because aws s3 commands automatically perform multipart uploading and downloading based on the file size. Important: It's a best practice to use aws s3 commands, such as aws s3 cp, for multipart uploads and downloads. For more information about these two command tiers, see Using Amazon S3 with the AWS CLI. Log.Use the AWS CLI with either high-level aws s3 commands or low-level aws s3api commands to upload large files to Amazon S3. Log.i('ListingImages',' query count='+cur.getCount()) which image properties are we queryingĬontentResolver cr = getContentResolver()

It's a good example and you can update it using query() from a ContentResolver object rather than managedQuery() that is deprecated.

This forms a SQL Statement as : SELECT bucket_id, bucket_display_name, datetaken, _data FROM images WHERE (1) GROUP BY bucket_id,(bucket_display_name) ORDER BY date_modified DESCĪs pointed out, This code needs to be improved for targeting Android Q. Log.d('AlbumScanner', 'bucketId : $bucketId | name : $name | count : $count | path : $path') Val countCursor = contentResolver.query(contentUri, arrayOf( 'count(' + ._ID + ')'), selection, null, null) Val selection = _ID + '='' + bucketId + ''' Val path = cursor.getString(cursor.getColumnIndexOrThrow()) // Thumb image path Val name = cursor.getString(cursor.getColumnIndexOrThrow(_DISPLAY_NAME)) Val bucketId = cursor.getString(cursor.getColumnIndexOrThrow(_ID)) Val cursor = contentResolver.query(contentUri, projection, bucketGroupBy, null, bucketOrderBy) * public static final int MEDIA_TYPE_VIDEO = 3 įun getAlbumList(mediaType: Int, contentResolver: ContentResolver) ' * public static final int MEDIA_TYPE_IMAGE = 1 Use following function to get albums of Video or Images : /* ImageUrls Arraylist is containing path of last modifided image of album you can use it as thumbnail ImageBuckets Arraylist is containing album names ImageUrls.add(imagecursor.getString(dataColumnIndex)) Int dataColumnIndex = imagecursor.getColumnIndex() String bucketDisplayName = imagecursor.getString(bucketColumnIndex) Int bucketColumnIndex = imagecursor.getColumnIndex(_DISPLAY_NAME) String BUCKET_GROUP_BY = '1) GROUP BY 1,(2' Ĭursor imagecursor = managedQuery(images,īUCKET_GROUP_BY, // Which rows to return (all rows)įor (int i = 0 i < imagecursor.getCount() i++) String BUCKET_ORDER_BY = _MODIFIED + ' DESC'

it works for me: Uri images = _CONTENT_URI Log.i('ListingImages', ' bucket=' + bucket Log.i('ListingImages',' query count=' + cur.getCount())

Images, PROJECTION_BUCKET, BUCKET_GROUP_BY, null, BUCKET_ORDER_BY) Get the base URI for the People table in the Contacts content provider. String BUCKET_ORDER_BY = 'MAX(datetaken) DESC' Note that because there is a ')' in the template, we use The '1,(2)' means the first two columns specified The template for 'WHERE' parameter is like: 'WHERE' parameter to insert a 'GROUP BY' clause into the SQL statement. We want to order the albums by reverse chronological order. (Note that bucket repeat is removed by groupby & order technique) // which image properties are we querying I have the same problem and here is my solution (after tracing gallery source code) to get album name and the first image in it (can use as thumbnail for this album):
