I got the list of Package name & Label of installed application in database, Now I want to interception with installed application and database. Suppose any application delete from device then I want changes in Database. for that i am using broadcast receiver but my code not works.

PackageManager pm = this.getPackageManager();
List < ApplicationInfo > list = getPackageManager().getInstalledApplications(PackageManager.PERMISSION_GRANTED);
for (int n = 0; n < list.size(); n++) {
    Apps.add(list.get(n).loadLabel(pm).toString());
    AppsP.add(list.get(n).packageName.toString());
    Log.w("Installed Applications", list.get(n).loadLabel(pm).toString());
    Log.w("Installed Applications Package", list.get(n).packageName.toString());


    ...
    In other class

    public class PackageReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub
            if (intent.getAction().equalsIgnoreCase(Intent.ACTION_PACKAGE_ADDED)) {
                String added_package = intent.getData().toString();
                Log.i("PackageReceiver", "Package Added = " + added_package);

            } else if (intent.getAction().equalsIgnoreCase(Intent.ACTION_PACKAGE_REMOVED)) {
                String removed_package = intent.getData().toString();
                MyDBHelper DB = new MyDBHelper(context);
                Log.i("PackageReceiver", "Package removed = " + removed_package);
                DB.open();
                DB.deleteStmt = DB.db.compileStatement(QueryManager.ApplicationDelete);
                DB.deleteStmt.bindString(1, removed_package);
                DB.close();

            }
