PackageManager in Android giving duplicates -

i might novice programmer packagemanager complicated ! going show makes no sense:

i able pull out names of applications on device if try save array can save half of them.

        packagemanager packagemanager = null;     list<applicationinfo> appslisttest = new arraylist<applicationinfo>();     packagemanager = context.getpackagemanager();     appslisttest = packagemanager.getinstalledapplications(0);     log.d("log", " new pm : " + appslisttest.size());      iterator<applicationinfo> iterator = appslisttest.iterator();     int counter = 0;     string[] appname = new string[appslisttest.size()];     while (iterator.hasnext()) {          log.d("log", string.valueof(counter));     //  when print out see 64 apps. great         log.d("log", (string) iterator.next().loadlabel(packagemanager));     //  when try save array 30                     appname[counter] = (string) iterator.next().loadlabel(packagemanager);         counter++;       } 

it makes no sense !!!

so if comment out appname array print log.d out 61 times. when include array log out 31 times.

and value initialise appname 64:

log.d("log", " new pm : " + appslisttest.size()); 

application not crash or anything.

can show me code on how app name, uid , icon ?

iterator.next() advances list - advancing twice per loop. instead, should save result iterator.next() variable , use within loop:

while (iterator.hasnext()) {     log.d("log", string.valueof(counter));     // call iterator.next() once per loop     applicationinfo info = iterator.next();     string label = (string) info.loadlabel(packagemanager);     log.d("log", label);     appname[counter] = label;     counter++; }
