How to get installed application name in android?

I have made a small method to display the installed application name in android. But when i give "name" attribute its showing exception error. And when i give "packageName" the method executes perfectly and displays the package name in a list

private void getInstalledApps() {
// TODO Auto-generated method stub
PackageManager packageManager=this.getPackageManager();
List<ApplicationInfo applist=packageManager.getInstalledApplications(0);


Iterator<ApplicationInfo> it=applist.iterator();
while(it.hasNext()){
ApplicationInfo pk=(ApplicationInfo)it.next();

String appname=pk.name.toString();

installedapplist.add(appname);
}

}


In the above code when i give
String appname=pk.packageName.toString()
it works fine but when I give
String appname=pk.name.toString()
the program is throwing an exception error. Please help me to sort out the problem.

My guess is your code is throwing a NullPointerException because the name field is null. In any event, what you probably want is:

String appname = packageManager.getApplicationLabel(pk).toString()
