public class ContentUris
extends Object

java.lang.Object
↳	android.content.ContentUris

Utility methods useful for working with 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.

Public constructors
`ContentUris()`

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

From class java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

ContentUris ()

Added in API level 1

Uri.Builder appendId (Uri.Builder builder, 
                long id)

Appends the given ID to the end of the path.

Parameters
`builder`	`Uri.Builder`: to append the ID to
`id`	`long`: to append

Returns
`Uri.Builder`	the given builder

Added in API level 1

long parseId (Uri contentUri)

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`

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

Throws
`UnsupportedOperationException`	if this isn't a hierarchical URI
`NumberFormatException`	if the last segment isn't a number

Added in API level 1

Uri withAppendedId (Uri contentUri, 
                long id)

Appends the given ID to the end of the path.

Parameters
`contentUri`	`Uri`: to start with
`id`	`long`: to append

Returns
`Uri`	a new URI with the given ID appended to the end of the path
