This is the source code...

public class GetAppList extends Activity {         @Override     public void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);     setContentView(R.layout.main);     try {         List<PackageInfo> appListInfo = this.getPackageManager()         .getInstalledPackages(0);         JSONArray ja = new JSONArray();         for (PackageInfo p : appListInfo) {             if (p.applicationInfo.uid > 10000) {                 JSONObject jo = new JSONObject();                 jo.put("label", p.applicationInfo.name);                 jo.put("packageName", p.applicationInfo.packageName);                 ja.put(jo);             }           }         System.out.println(ja);     } catch (Exception e) {         // TODO: handle exception     }      } }

Here's a snippet illustrating what you want to do:

     public InstalledPackage(PackageManager pm, ApplicationInfo ai, Drawable defaultIcon) {         name = ai.packageName;         icon = defaultIcon;         pkg = ai.packageName;         if (ai.labelRes != 0) {             name = (String) pm.getText(ai.packageName, ai.labelRes, ai);         }         if (ai.icon != 0) {             icon = pm.getDrawable(ai.packageName, ai.icon, ai);         }     } 

Keep in mind many packages won't have a label.

Solution:

    JSONArray ja = new JSONArray();     try {         HttpClient httpclient = new DefaultHttpClient();         HttpPost request = new HttpPost(sendDataUrl.toString());         List<NameValuePair> params = new ArrayList<NameValuePair>();         PackageManager pm = context.getPackageManager();         List<PackageInfo> appListInfo = pm.getInstalledPackages(0);         for (PackageInfo p : appListInfo) {             if (p.applicationInfo.uid > 10000) {                 JSONObject jo = new JSONObject();                 jo.put("label", p.applicationInfo.loadLabel(pm).toString());                 jo.put("packageName", p.applicationInfo.packageName);                 ja.put(jo);             }          }
