Try this, it works fine for me:

1 . Modify your MainActivity section in AndroidManifest.xml, delete from it, line with MAIN category in intent-filter section

    
        ==>  <== Delete this line
        
    

2 . Create , for each of your icons. Like this

3 . Set programmatically: set ENABLE attribute for the appropriate activity-alias

 getPackageManager().setComponentEnabledSetting(
        new ComponentName("ru.quickmessage.pa", "ru.quickmessage.pa.MainActivity-Red"), 
            PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

Note, At least one must be enabled at all times.
