Question

每次创建Homescreen / Launcher上的新快捷方式时，我都会尝试接收活动。我当前的配置如下所示，但如果快捷方式是从菜单中拖放创建的，则我从未收到任何事件

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />    
<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />
<application>
  <receiver  
     android:name=".InstallShortcutReceiver">
    <intent-filter>
      <action android:name="com.android.launcher.action.INSTALL_SHORTCUT" />
    </intent-filter>
  </receiver>
</application>

我的想法可能吗？

最诚挚的问候，André

public class OnBootReceiver extends BroadcastReceiver {

        private final Context context;

        public CheckShortcutsTask(Context context) {
            this.context = context;
        }

        @Override
        public void run() {
            try {

            } catch( Exception e ) {
                Log.e("pweb", "Exception in " + CheckShortcutsTask.class, e);

    @Override

public List<Shortcut> getShortcuts( ContentResolver resolver ) throws Exception {

        shortcut.intent  = Intent.parseUri( s, 0 );
        shortcuts.add( shortcut );
    }

    cursor.close();

    return shortcuts;
}

如何获知拖放快捷方式的创建？
