Android dynamic Edit App Desktop icon

Principle:
In the manifest file, use the <activity-alias> tag to prepare multiple for our entry activity, with the <activity-alias> tag activity to point to the entry activity, Each activity with <activity-alias> tags can be set up with an icon individually, in which we dynamically set &LT;ACTIVITY-ALIAS&GT, and then kill launcher, When the launcher restarts, Icon replaces the note:
Kill launcher need to add permission <uses-permission android:name= "Android.permission.KILL_BACKGROUND_PROCESSES"/> Code:
