/**
|
75 |
|
|
* This function creates a shortcut and returns it to the caller. There are actually two
|
76 |
|
|
* intents that you will send back.
|
77 |
|
|
*
|
78 |
|
|
* The first intent serves as a container for the shortcut and is returned to the launcher by
|
79 |
|
|
* setResult(). This intent must contain three fields:
|
80 |
|
|
*
|
81 |
|
|
* <ul>
|
82 |
|
|
* <li>{@link android.content.Intent#EXTRA_SHORTCUT_INTENT} The shortcut intent.</li>
|
83 |
|
|
* <li>{@link android.content.Intent#EXTRA_SHORTCUT_NAME} The text that will be displayed with
|
84 |
|
|
* the shortcut.</li>
|
85 |
|
|
* <li>{@link android.content.Intent#EXTRA_SHORTCUT_ICON} The shortcut's icon, if provided as a
|
86 |
|
|
* bitmap, <i>or</i> {@link android.content.Intent#EXTRA_SHORTCUT_ICON_RESOURCE} if provided as
|
87 |
|
|
* a drawable resource.</li>
|
88 |
|
|
* </ul>
|
89 |
|
|
*
|
90 |
|
|
* If you use a simple drawable resource, note that you must wrapper it using
|
91 |
|
|
* {@link android.content.Intent.ShortcutIconResource}, as shown below. This is required so
|
92 |
|
|
* that the launcher can access resources that are stored in your application's .apk file. If
|
93 |
|
|
* you return a bitmap, such as a thumbnail, you can simply put the bitmap into the extras
|
94 |
|
|
* bundle using {@link android.content.Intent#EXTRA_SHORTCUT_ICON}.
|
95 |
|
|
*
|
96 |
|
|
* The shortcut intent can be any intent that you wish the launcher to send, when the user
|
97 |
|
|
* clicks on the shortcut. Typically this will be {@link android.content.Intent#ACTION_VIEW}
|
98 |
|
|
* with an appropriate Uri for your content, but any Intent will work here as long as it
|
99 |
|
|
* triggers the desired action within your Activity.
