public final class NavDeepLinkBuilder

Class used to construct deep links to a particular destination in a NavGraph.

When this deep link is triggered:

The task is cleared.
The destination and all of its parents will be on the back stack.
Calling NavController.navigateUp will navigate to the parent of the destination.

The parent of the destination is the start destination of the containing navigation graph. In the cases where the destination is the start destination of its containing navigation graph, the start destination of its grandparent is used.

You can construct an instance directly with NavDeepLinkBuilder or build one using an existing NavController via NavController.createDeepLink.

If the context passed in here is not an Activity, this method will use android.content.pm.PackageManager.getLaunchIntentForPackage as the default activity to launch, if available.

Public constructors

NavDeepLinkBuilder

Added in 1.0.0

public NavDeepLinkBuilder(@NonNull Context context)

Parameters
`@NonNull Context context`	Context used to create deep links

Public methods

addDestination

Added in 2.4.0

public final @NonNull NavDeepLinkBuilder addDestination(@IdRes int destId, Bundle args)

Add a new destination id to deep link to. This builds off any previous calls to this method or calls to setDestination, building the minimal synthetic back stack of start destinations between the previous deep link destination and the newly added deep link destination.

This means that if R.navigation.nav_graph has startDestination= R.id.start_destination,

navDeepLinkBuilder
   .setGraph(R.navigation.nav_graph)
   .addDestination(R.id.second_destination, null)

is equivalent to

navDeepLinkBuilder
   .setGraph(R.navigation.nav_graph)
   .addDestination(R.id.start_destination, null)
   .addDestination(R.id.second_destination, null)

Use the second form to assign specific arguments to the start destination.

Parameters
`@IdRes int destId`	destination ID to deep link to.
`Bundle args`	Arguments to pass to this destination and any synthetic back stack created due to this destination being added.

Returns
`@NonNull NavDeepLinkBuilder`	this object for chaining

addDestination

Added in 2.4.0

public final @NonNull NavDeepLinkBuilder addDestination(@NonNull String route, Bundle args)

Add a new destination route to deep link to. This builds off any previous calls to this method or calls to .setDestination, building the minimal synthetic back stack of start destinations between the previous deep link destination and the newly added deep link destination.

Parameters
`@NonNull String route`	destination route to deep link to.
`Bundle args`	Arguments to pass to this destination and any synthetic back stack created due to this destination being added.

Returns
`@NonNull NavDeepLinkBuilder`	this object for chaining

createPendingIntent

Added in 1.0.0

public final @NonNull PendingIntent createPendingIntent()

Construct a PendingIntent to the deep link destination.

This constructs the entire task stack needed.

You must have set a NavGraph and set a destination before calling this method.

Returns
`@NonNull PendingIntent`	a PendingIntent constructed with `TaskStackBuilder.getPendingIntent` to deep link to the given destination

createTaskStackBuilder

Added in 1.0.0

public final @NonNull TaskStackBuilder createTaskStackBuilder()

Construct the full task stack needed to deep link to the given destination.

You must have set a NavGraph and set a destination before calling this method.

Returns
`@NonNull TaskStackBuilder`	a `TaskStackBuilder` which can be used to `send the deep link` or `create a PendingIntent` to deep link to the given destination.

setArguments

Added in 1.0.0

public final @NonNull NavDeepLinkBuilder setArguments(Bundle args)

Set optional arguments to send onto every destination created by this deep link.

Parameters
`Bundle args`	arguments to pass to each destination

Returns
`@NonNull NavDeepLinkBuilder`	this object for chaining

setComponentName

Added in 1.0.0

public final @NonNull NavDeepLinkBuilder setComponentName(@NonNull Class<Activity> activityClass)

Sets an explicit Activity to be started by the deep link created by this class.

Parameters
`@NonNull Class<Activity> activityClass`	The Activity to start. This Activity should have a `NavController` which uses the same `NavGraph` used to construct this deep link.

Returns
`@NonNull NavDeepLinkBuilder`	this object for chaining

setComponentName

Added in 1.0.0

public final @NonNull NavDeepLinkBuilder setComponentName(@NonNull ComponentName componentName)

Sets an explicit Activity to be started by the deep link created by this class.

Parameters
`@NonNull ComponentName componentName`	The Activity to start. This Activity should have a `NavController` which uses the same `NavGraph` used to construct this deep link.

Returns
`@NonNull NavDeepLinkBuilder`	this object for chaining

setDestination

Added in 2.4.0

public final @NonNull NavDeepLinkBuilder setDestination(@IdRes int destId, Bundle args)

Sets the destination id to deep link to. Any destinations previous added via addDestination are cleared, effectively resetting this object back to only this single destination.

Parameters
`@IdRes int destId`	destination ID to deep link to.
`Bundle args`	Arguments to pass to this destination and any synthetic back stack created due to this destination being added.

Returns
`@NonNull NavDeepLinkBuilder`	this object for chaining

setDestination

Added in 2.4.0

public final @NonNull NavDeepLinkBuilder setDestination(@NonNull String destRoute, Bundle args)

Sets the destination route to deep link to. Any destinations previous added via .addDestination are cleared, effectively resetting this object back to only this single destination.

Parameters
`@NonNull String destRoute`	destination route to deep link to.
`Bundle args`	Arguments to pass to this destination and any synthetic back stack created due to this destination being added.

Returns
`@NonNull NavDeepLinkBuilder`	this object for chaining

setGraph

Added in 1.0.0

public final @NonNull NavDeepLinkBuilder setGraph(@NavigationRes int navGraphId)

Sets the graph that contains the deep link destination.

Parameters
`@NavigationRes int navGraphId`	ID of the `NavGraph` containing the deep link destination

Returns
`@NonNull NavDeepLinkBuilder`	this object for chaining

Added in 1.0.0

public final @NonNull NavDeepLinkBuilder setGraph(@NonNull NavGraph navGraph)

Sets the graph that contains the deep link destination.

If you do not have access to a NavController, you can create a NavigatorProvider and use that to programmatically construct a navigation graph or use NavInflater.

Parameters
`@NonNull NavGraph navGraph`	The `NavGraph` containing the deep link destination

Returns
`@NonNull NavDeepLinkBuilder`	this object for chaining
