How to get List of all installed application from device

Hello Friends, We will see  how to  get list of all installed application from android device programmatically,

We call a method of PackageManager like

List<PackageInfo> packs = pm.getInstalledPackages(0);

It returns a list of packageInfo object. Now we will strore our app list in ArrayList.

As shown below.


/**
 * 
 * @param context
 * @param getSysPackages
 * @return List of installed application from the device
 */
private ArrayList<PInfo> getApps(Context context, boolean getSysPackages) {
           final PackageManager pm = context.getPackageManager();

          ArrayList<PInfo> res = new ArrayList<PInfo>();
        
          List<PackageInfo> packs = pm.getInstalledPackages(0);
         for (int i = 0; i < packs.size(); i++) {
                PackageInfo p = packs.get(i);

                if ((!getSysPackages) && (p.versionName == null)) {
                     continue;
                }

         ApplicationInfo appinfo = p.applicationInfo;

         if(((appinfo.flags & ApplicationInfo.FLAG_SYSTEM) != (getSysPackages   ? 1: ))))
                continue;

         if (pm.getLaunchIntentForPackage(p.packageName) == null) {
                 continue;
         }

         PInfo info = new PInfo();
         info.appname= p.applicationInfo.loadLabel(pm).toString();
         info.pname = p.packageName;
         info.icon = p.applicationInfo.loadIcon(pm);
        res.add(newInfo);
    }

    Collections.sort(res, new AlPhabeticalComparator());

    return res;
}

Now we have a list, we will just sort our array in alphabetical order using Java Collection API.
For that we require our custom comparator.

Create a Inner static class AlPhabeticalComarator

public static class AlPhabeticalComparator implements Comparator<PInfo> {
     @Override
     public int compare(PInfo info1, PInfo info2) {
          return info1.appname.toUpperCase().compareTo(info2.appname.toUpperCase());
     }
}

To store information of each application we require a Class Object Create as follows

Create a inner class as PInfo.


          /**
          * Static Inner class to hold application info
          **/
          public static class PInfo {                 public String appname = "";
                 public String pname = "";
                 public Drawable icon;

  1. Thanks dude.. aweome, I was searching for :

    public static class AlPhabeticalComparator implements Comparator {
    @Override
    public int compare(PInfo info1, PInfo info2) {
    return info1.appname.toUpperCase().compareTo(info2.appname.toUpperCase());
    }
    }
