Query the given URI, returning a Cursor
over the result set
with optional support for cancellation.
For best performance, the caller should follow these guidelines:
selection
parameter, so that queries
that differ only by those values will be recognized as the same
for caching purposes.uri | The URI, using the content:// scheme, for the content to retrieve. |
---|---|
projection | A list of which columns to return. Passing null will return all columns, which is inefficient. |
selection | A filter declaring which rows to return, formatted as an SQL WHERE clause (excluding the WHERE itself). Passing null will return all rows for the given URI. |
selectionArgs | You may include ?s in selection, which will be replaced by the values from selectionArgs, in the order that they appear in the selection. The values will be bound as Strings. |
sortOrder | How to order the rows, formatted as an SQL ORDER BY clause (excluding the ORDER BY itself). Passing null will use the default sort order, which may be unordered. |
cancellationSignal | A signal to cancel the operation in progress, or null if none.
If the operation is canceled, then OperationCanceledException will be thrown
when the query is executed. |
