How to open application android programmatically if i don't know package name -

i know open application pro grammatically can :

intent launchintent = getpackagemanager().getlaunchintentforpackage("com.package.name"); startactivity(launchintent); 

however, how if don't know package name; application name ?

thanks!

edit: tried package name opening app , checking logs package name didn't show up.

maybe help, have add terrible approach app names can same different apps, , apps (like "contacts") have different labels based on language set

     /**      *      * @param appname target app launch, if there multiple apps same name, first found launched      * @throws illegalargumentexception if target app not found      */     public void runapp(string appname) throws illegalargumentexception {         intent mainintent = new intent(intent.action_main, null);         mainintent.addcategory(intent.category_launcher);         ( resolveinfo info : getpackagemanager().queryintentactivities( mainintent, 0) ) {             if ( info.loadlabel(getpackagemanager()).equals(appname) ) {                 intent launchintent = getpackagemanager().getlaunchintentforpackage(info.activityinfo.applicationinfo.packagename);                 startactivity(launchintent);                 return;             }         }         throw new illegalargumentexception("application not found!");     }
