ContentUris

Kotlin |Java

open class ContentUris

kotlin.Any
↳	android.content.ContentUris

Utility methods useful for working with android.net.Uri objects that use the "content" (content://) scheme.

Content URIs have the syntax

content://authority/path/id

content:: The scheme portion of the URI. This is always set to ContentResolver.SCHEME_CONTENT (value content://).
authority: A string that identifies the entire content provider. All the content URIs for the provider start with this string. To guarantee a unique authority, providers should consider using an authority that is the same as the provider class' package identifier.
path: Zero or more segments, separated by a forward slash (/), that identify some subset of the provider's data. Most providers use the path part to identify individual tables. Individual segments in the path are often called "directories" although they do not refer to file directories. The right-most segment in a path is often called a "twig"
id: A unique numeric identifier for a single row in the subset of data identified by the preceding path part. Most providers recognize content URIs that contain an id part and give them special handling. A table that contains a column named _ID often expects the id part to be a particular value for that column.

Summary

Public constructors
`ContentUris()`

Public methods
open static Uri.Builder	`appendId(builder: Uri.Builder, id: Long)` Appends the given ID to the end of the path.
open static Long	`parseId(contentUri: Uri)` Converts the last path segment to a long.
open static Uri	`removeId(contentUri: Uri)` Removes any ID from the end of the path.
open static Uri	`withAppendedId(contentUri: Uri, id: Long)` Appends the given ID to the end of the path.

ContentUris()

open static fun appendId(
    builder: Uri.Builder, 
    id: Long
): Uri.Builder

Appends the given ID to the end of the path.

Parameters
`builder`	Uri.Builder: to append the ID to This value cannot be `null`.
`id`	Long: to append

Return
`Uri.Builder`	the given builder This value cannot be `null`.

open static fun parseId(contentUri: Uri): Long

Converts the last path segment to a long.

This supports a common convention for content URIs where an ID is stored in the last segment.

Parameters
`contentUri`	Uri: This value cannot be `null`.

Return
`Long`	the long conversion of the last segment or -1 if the path is empty

Exceptions
`java.lang.UnsupportedOperationException`	if this isn't a hierarchical URI
`java.lang.NumberFormatException`	if the last segment isn't a number

open static fun removeId(contentUri: Uri): Uri

Removes any ID from the end of the path.

Parameters
`contentUri`	Uri: that ends with an ID This value cannot be `null`.

Return
`Uri`	a new URI with the ID removed from the end of the path This value cannot be `null`.

Exceptions
`java.lang.IllegalArgumentException`	when the given URI has no ID to remove from the end of the path

open static fun withAppendedId(
    contentUri: Uri, 
    id: Long
): Uri

Appends the given ID to the end of the path.

Parameters
`contentUri`	Uri: to start with This value cannot be `null`.
`id`	Long: to append

Return
`Uri`	a new URI with the given ID appended to the end of the path This value cannot be `null`.
