Get list of installed android applications

Hi I want to get a list of all of the installed applications on the users device I have been googling for the longest time but can't find what i want this link was the closest though and works fine except me being new don't understand how to use the method getPackages(); and create a list with it

Any help on how to create the actual list would be a major help i have all that code already in just can't get the list to actually show thanks for any help

I was working on something like this recently. One thing I'll say up front is to be sure and perform this in a separate thread -- querying the application information is SLOW. The following will get you a list of ALL the installed applications. This will include a lot of system apps that you probably aren't interested in.

PackageManager pm = getPackageManager();
List<ApplicationInfo> apps = pm.getInstalledApplications(0);

To limit it to just the user-installed or updated system apps (e.g. Maps, GMail, etc), I used the following logic:

List<ApplicationInfo> installedApps = new ArrayList<ApplicationInfo>();

for(ApplicationInfo app : apps) {
    //checks for flags; if flagged, check if updated system app
    if((app.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {
    //it's a system app, not interested
    } else if ((app.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
        //Discard this one
    //in this case, it should be a user-installed app
    } else {

EDIT: Also, to get the name and icon for the app (which is probably what takes the longest -- I haven't done any real deep inspection on it -- use this:

String label = (String)pm.getApplicationLabel(app);
Drawable icon = pm.getApplicationIcon(app);

installedApps should have a full list of the apps you need, now. Hope this helps, but you may have to modify the logic a bit depending on what apps you need to have returned. Again, it is SLOW, but it's just something you have to work around. You might want to build a data cache in a database if it's something you'll be accessing frequently.
