ShortcutManager
executes operations on an app's set of shortcuts, which
represent specific tasks and actions that users can perform within your app. This page lists
components of the ShortcutManager
class that you can use to create and manage
sets of shortcuts.
To learn about methods that retrieve information about a single shortcut—including
identifiers, type, and status—read the
ShortcutInfo
reference.
For guidance about using shortcuts, see App shortcuts.

Public methods
addDynamicShortcuts
public boolean addDynamicShortcuts (List<ShortcutInfo> shortcutInfoList)
Publish the list of dynamic shortcuts. If there are already dynamic or pinned shortcuts with the same IDs, each mutable shortcut is updated.
This API will be rate-limited.
This method may take several seconds to complete, so it should
only be called from a worker thread.
Parameters | |
---|---|
shortcutInfoList |
List : This value cannot be null . |
Returns | |
---|---|
boolean |
true if the call has succeeded. false if the call is rate-limited. |
Throws | |
---|---|
IllegalArgumentException |
if getMaxShortcutCountPerActivity() is exceeded,
or when trying to update immutable shortcuts. |
IllegalStateException |
when the user is locked. |
createShortcutResultIntent
public Intent createShortcutResultIntent (ShortcutInfo shortcut)
Returns an Intent which can be used by the default launcher to pin a shortcut containing the
given ShortcutInfo
. This method should be used by an Activity to set a result in
response to Intent#ACTION_CREATE_SHORTCUT
.
This method may take several seconds to complete, so it should
only be called from a worker thread.
Parameters | |
---|---|
shortcut |
ShortcutInfo : New shortcut to pin. If an app wants to pin an existing (either dynamic
or manifest) shortcut, then it only needs to have an ID, and other fields don't have to
be set, in which case, the target shortcut must be enabled.
If it's a new shortcut, all the mandatory fields, such as a short label, must be
set.
This value cannot be null . |
Returns | |
---|---|
Intent |
The intent that should be set as the result for the calling activity, or
null if the current launcher doesn't support shortcuts. |
Throws | |
---|---|
IllegalArgumentException |
if a shortcut with the same ID exists and is disabled. |

getDynamicShortcuts
public List<ShortcutInfo> getDynamicShortcuts ()
Return all dynamic shortcuts from the caller app.
This API is intended to be used for examining what shortcuts are currently published.
Re-publishing returned ShortcutInfo
s via APIs such as
setDynamicShortcuts(java.util.List)
may cause loss of information such as icons.
This method may take several seconds to complete, so it should
only be called from a worker thread.

reportShortcutUsed
public void reportShortcutUsed (String shortcutId)
Apps that publish shortcuts should call this method whenever the user selects the shortcut containing the given ID or when the user completes an action in the app that is equivalent to selecting the shortcut. For more details, read about tracking shortcut usage.
The information is accessible via UsageStatsManager#queryEvents
Typically, launcher apps use this information to build a prediction model
so that they can promote the shortcuts that are likely to be used at the moment.
Parameters | |
---|---|
shortcutId |
String |
Throws | |
---|---|
IllegalStateException |
when the user is locked. |
requestPinShortcut
public boolean requestPinShortcut (ShortcutInfo shortcut, IntentSender resultIntent)
Request to create a pinned shortcut. The default launcher will receive this request and
ask the user for approval. If the user approves it, the shortcut will be created, and
resultIntent
will be sent. If a request is denied by the user, however, no response
will be sent to the caller.
Only apps with a foreground activity or a foreground service can call this method.
Otherwise, it'll throw IllegalStateException
.
It's up to the launcher to decide how to handle previous pending requests when the same package calls this API multiple times in a row. One possible strategy is to ignore any previous requests.
Note: See also the support library counterpart
ShortcutManagerCompat.requestPinShortcut(Context, ShortcutInfoCompat, IntentSender)
,
which supports Android versions lower than VERSION_CODES#O
using the
legacy private intent com.android.launcher.action.INSTALL_SHORTCUT
.
This method may take several seconds to complete, so it should
only be called from a worker thread.
Parameters | |
---|---|
shortcut |
ShortcutInfo : Shortcut to pin. If an app wants to pin an existing (either static
or dynamic) shortcut, then it only needs to have an ID. Although other fields don't have
to be set, the target shortcut must be enabled.
If it's a new shortcut, all the mandatory fields, such as a short label, must be
set.
This value cannot be |
resultIntent |
IntentSender : If not null, this intent will be sent when the shortcut is pinned.
Use PendingIntent.getIntentSender() to create an IntentSender .
To avoid background execution limits, use an unexported, manifest-declared receiver.
For more details, see
Creating pinned shortcuts. |
Returns | |
---|---|
boolean |
TRUE if the launcher supports this feature. Note the API will return without
waiting for the user to respond, so getting TRUE from this API does *not* mean
the shortcut was pinned successfully. FALSE if the launcher doesn't support this
feature or if calling app belongs to a user-profile with items restricted on home screen. |
Throws | |
---|---|
IllegalArgumentException |
if a shortcut with the same ID exists and is disabled. |
IllegalStateException |
The caller doesn't have a foreground activity or a foreground service, or the device is locked. |
setDynamicShortcuts
public boolean setDynamicShortcuts (List<ShortcutInfo> shortcutInfoList)
Publish the list of shortcuts. All existing dynamic shortcuts from the caller app will be replaced. If there are already pinned shortcuts with the same IDs, the mutable pinned shortcuts are updated.

only be called from a worker thread.
Parameters | |

Returns | |
---|---|
boolean |
true if the call has succeeded. false if the call is rate-limited. |

or when trying to update immutable shortcuts. |
IllegalStateException |
when the user is locked. |
updateShortcuts
public boolean updateShortcuts (List<ShortcutInfo> shortcutInfoList)
