ContactsContract.StreamItemPhotos

Class Overview

Constants for the stream_item_photos table, which contains photos associated with social stream updates.

Access to social stream photos requires additional permissions beyond the read/write contact permissions required by the provider. Querying for social stream photos requires android.permission.READ_SOCIAL_STREAM permission, and inserting or updating social stream photos requires android.permission.WRITE_SOCIAL_STREAM permission.

Account check

The content URIs to the insert, update and delete operations are required to have the account information matching that of the owning raw contact as query parameters, namely ACCOUNT_TYPE and ACCOUNT_NAME . DATA_SET isn't required.

Operations

Insert

Social stream photo entries are associated with a social stream item. Photos can be inserted into a social stream item in a couple of ways:

Via the CONTENT_DIRECTORY sub-path of a stream item:

            ContentValues values = new ContentValues();
 values.put(StreamItemPhotos.SORT_INDEX, 1);
 values.put(StreamItemPhotos.PHOTO, photoData);
 Uri.Builder builder = StreamItems.CONTENT_URI.buildUpon();
 ContentUris.appendId(builder, streamItemId);
 builder.appendEncodedPath(StreamItems.StreamItemPhotos.CONTENT_DIRECTORY);
 builder.appendQueryParameter(RawContacts.ACCOUNT_NAME, accountName);
 builder.appendQueryParameter(RawContacts.ACCOUNT_TYPE, accountType);
 Uri photoUri = getContentResolver().insert(builder.build(), values);
 long photoId = ContentUris.parseId(photoUri);
           

Via the CONTENT_PHOTO_URI URI:

            ContentValues values = new ContentValues();
 values.put(StreamItemPhotos.STREAM_ITEM_ID, streamItemId);
 values.put(StreamItemPhotos.SORT_INDEX, 1);
 values.put(StreamItemPhotos.PHOTO, photoData);
 Uri.Builder builder = StreamItems.CONTENT_PHOTO_URI.buildUpon();
 builder.appendQueryParameter(RawContacts.ACCOUNT_NAME, accountName);
 builder.appendQueryParameter(RawContacts.ACCOUNT_TYPE, accountType);
 Uri photoUri = getContentResolver().insert(builder.build(), values);
 long photoId = ContentUris.parseId(photoUri);
           

Update

Updates can only be made against a specific ContactsContract.StreamItems.StreamItemPhotos entry, identified by both the stream item ID it belongs to and the stream item photo ID. This can be specified in two ways.

Via the CONTENT_DIRECTORY sub-path of a stream item:

            ContentValues values = new ContentValues();
 values.put(StreamItemPhotos.PHOTO, newPhotoData);
 Uri.Builder builder = StreamItems.CONTENT_URI.buildUpon();
 ContentUris.appendId(builder, streamItemId);
 builder.appendEncodedPath(StreamItems.StreamItemPhotos.CONTENT_DIRECTORY);
 ContentUris.appendId(builder, streamItemPhotoId);
 builder.appendQueryParameter(RawContacts.ACCOUNT_NAME, accountName);
 builder.appendQueryParameter(RawContacts.ACCOUNT_TYPE, accountType);
 getContentResolver().update(builder.build(), values, null, null);
           

Via the CONTENT_PHOTO_URI URI:

            ContentValues values = new ContentValues();
 values.put(StreamItemPhotos.STREAM_ITEM_ID, streamItemId);
 values.put(StreamItemPhotos.PHOTO, newPhotoData);
 Uri.Builder builder = StreamItems.CONTENT_PHOTO_URI.buildUpon();
 builder.appendQueryParameter(RawContacts.ACCOUNT_NAME, accountName);
 builder.appendQueryParameter(RawContacts.ACCOUNT_TYPE, accountType);
 getContentResolver().update(builder.build(), values);
           

Delete

Deletes can be made against either a specific photo item in a stream item, or against all or a selected subset of photo items under a stream item. For example:

Deleting a single photo via the CONTENT_DIRECTORY sub-path of a stream item:

           Uri.Builder builder = StreamItems.CONTENT_URI.buildUpon();
 ContentUris.appendId(builder, streamItemId);
 builder.appendEncodedPath(StreamItems.StreamItemPhotos.CONTENT_DIRECTORY);
 ContentUris.appendId(builder, streamItemPhotoId);
 builder.appendQueryParameter(RawContacts.ACCOUNT_NAME, accountName);
 builder.appendQueryParameter(RawContacts.ACCOUNT_TYPE, accountType);
 getContentResolver().delete(builder.build(), null, null);
          

Deleting all photos under a stream item

           Uri.Builder builder = StreamItems.CONTENT_URI.buildUpon();
 ContentUris.appendId(builder, streamItemId);
 builder.appendEncodedPath(StreamItems.StreamItemPhotos.CONTENT_DIRECTORY);
 builder.appendQueryParameter(RawContacts.ACCOUNT_NAME, accountName);
 builder.appendQueryParameter(RawContacts.ACCOUNT_TYPE, accountType);
 getContentResolver().delete(builder.build(), null, null);
          

Query

Querying for a specific photo in a stream item

          Cursor c = getContentResolver().query(
     ContentUris.withAppendedId(
         Uri.withAppendedPath(
             ContentUris.withAppendedId(StreamItems.CONTENT_URI, streamItemId)
             StreamItems.StreamItemPhotos#CONTENT_DIRECTORY),
         streamItemPhotoId), null, null, null, null);
         

Querying for all photos in a stream item

          Cursor c = getContentResolver().query(
     Uri.withAppendedPath(
         ContentUris.withAppendedId(StreamItems.CONTENT_URI, streamItemId)
         StreamItems.StreamItemPhotos#CONTENT_DIRECTORY),
     null, null, null, StreamItemPhotos.SORT_INDEX);
         

The record will contain both a PHOTO_FILE_ID and a PHOTO_URI . The PHOTO_FILE_ID can be used in conjunction with the ContactsContract.DisplayPhoto API to retrieve photo content, or you can open the PHOTO_URI as an asset file, as follows:

        public InputStream openDisplayPhoto(String photoUri) {
     try {
         AssetFileDescriptor fd = getContentResolver().openAssetFileDescriptor(photoUri, "r");
         return fd.createInputStream();
     } catch (IOException e) {
         return null;
     }
 }
