Makoto Onuki | 6f7362d9 | 2016-03-04 13:39:41 -0800 | [diff] [blame] | 29 | * {@link ShortcutManager} manages shortcuts created by applications. |
| 30 | * |
| 31 | * <h3>Dynamic shortcuts and pinned shortcuts</h3> |
| 32 | * |
| 33 | * An application can publish shortcuts with {@link #setDynamicShortcuts(List)} and |
| 34 | * {@link #addDynamicShortcut(ShortcutInfo)}. There can be at most |
| 35 | * {@link #getMaxDynamicShortcutCount()} number of dynamic shortcuts at a time from the same |
| 36 | * application. |
| 37 | * A dynamic shortcut can be deleted with {@link #deleteDynamicShortcut(String)}, and apps |
| 38 | * can also use {@link #deleteAllDynamicShortcuts()} to delete all dynamic shortcuts. |
| 39 | * |
| 40 | * <p>The shortcuts that are currently published by the above APIs are called "dynamic", because |
| 41 | * they can be removed by the creator application at any time. The user may "pin" dynamic shortcuts |
| 42 | * on Launcher to make "pinned" shortcuts. Pinned shortcuts <b>cannot</b> be removed by the creator |
| 43 | * app. An application can obtain all pinned shortcuts from itself with |
| 44 | * {@link #getPinnedShortcuts()}. Applications should keep the pinned shortcut information |
| 45 | * up-to-date using {@link #updateShortcuts(List)}. |
| 46 | * |
| 47 | * <p>The number of pinned shortcuts does not affect the number of dynamic shortcuts that can be |
| 48 | * published by an application at a time. |
| 49 | * No matter how many pinned shortcuts that Launcher has for an application, the |
| 50 | * application can still always publish {@link #getMaxDynamicShortcutCount()} number of dynamic |
| 51 | * shortcuts. |
| 52 | * |
| 53 | * <h3>Shortcut IDs</h3> |
| 54 | * |
| 55 | * Each shortcut must have an ID, which must be unique within each application. When a shortcut is |
| 56 | * published, existing shortcuts with the same ID will be updated. Note this may include a |
| 57 | * pinned shortcut. |
| 58 | * |
| 59 | * <h3>Rate limiting</h3> |
| 60 | * |
| 61 | * Calls to {@link #setDynamicShortcuts(List)}, {@link #addDynamicShortcut(ShortcutInfo)}, |
| 62 | * and {@link #updateShortcuts(List)} will be |
| 63 | * rate-limited. An application can call these methods at most |
| 64 | * {@link #getRemainingCallCount()} times until the rate-limiting counter is reset, |
| 65 | * which happens at a certain time every day. |
| 66 | * |
Makoto Onuki | 0e65d36 | 2016-03-29 14:46:50 -0700 | [diff] [blame] | 67 | * <p>An application can use {@link #getRateLimitResetTime()} to get the next reset time. |
| 68 | * |
| 69 | * <p>For testing purposes, use "Developer Options" (found in the Settings menu) to reset the |
| 70 | * internal rate-limiting counter. Automated tests can use the following ADB shell command to |
| 71 | * achieve the same effect:</p> |
| 72 | * <pre>adb shell cmd shortcut reset-throttling</pre> |

| 74 | * <h3>Backup and Restore</h3> |
| 75 | * |
| 76 | * Shortcuts will be backed up and restored across devices. This means all information, including |
| 77 | * IDs, must be meaningful on a different device. |
| 78 | * |
Makoto Onuki | 6f7362d9 | 2016-03-04 13:39:41 -0800 | [diff] [blame] | 79 | * <h3>APIs for launcher</h3> |
| 80 | * |
| 81 | * Launcher applications should use {@link LauncherApps} to get shortcuts that are published from |
| 82 | * applications. Launcher applications can also pin shortcuts with |
| 83 | * {@link LauncherApps#pinShortcuts(String, List, UserHandle)}. |
