broadcastreceiver - Android: detect when app is installed

Question

I am trying to download an Android app from a server using the DownloadManager class, install it and then detect when the installation is completed. I am using two receivers: one to detect the download process and the other to detect the install process. The first receiver works properly, but the second doesn't. What I am doing wrong?

DownloadManager dm = (DownloadManager) DownloadApplicationActivity.this.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request req = new DownloadManager.Request(Uri.parse(MY_LINK));
req.setTitle(MY_TITLE)
                .setDescription("Downloading ....")
                // download the package to the /sdcard/downlaod path.
                .setDestinationInExternalPublicDir(
                        Environment.DIRECTORY_DOWNLOADS,
                        MY_PATH);
        long enqueue = dm.enqueue(req);
BroadcastReceiver receiver= new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();
    if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
        Query query = new Query();
        query.setFilterById(enqueue);
        Cursor c =dm.query(query);
        if (c.moveToFirst()) {
            int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
            if (DownloadManager.STATUS_SUCCESSFUL == c.getInt(columnIndex)) {
                // show a notification bar.
                NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
                Notification notification = new Notification(R.drawable.icon,"",System.currentTimeMillis());

                notification.flags |= Notification.FLAG_AUTO_CANCEL;
                notification.flags |= Notification.FLAG_NO_CLEAR;
                Intent i = new Intent(Intent.ACTION_VIEW);
                // when the notification is clicked, install the app.
                        i.setDataAndType(Uri.fromFile(new File(Environment
                                .getExternalStorageDirectory() + APP_PATH)),"application/vnd.android.package-archive");
                        PendingIntent pendingIntent = PendingIntent.getActivity(
                                activity, 0, i, 0);
                        notification.setLatestEventInfo(activity, MY_TEXT, MY_TEXT,pendingIntent);
                        notification.number += 1;
                        notificationManager.notify( 0, notification);
                        //i want to detect the app's installation, I register a ne receiver
                        registerReceiver(installReceiver,new IntentFilter(Intent.ACTION_PACKAGE_ADDED));
            }
        }           
};  

BroadcastReceiver installReceiver= new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();
    if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {
        Uri data = intent.getData();
        String packageName = data.getEncodedSchemeSpecificPart();
        Log.i("The installed package is: ", "" + packageName);

            }
        }           
};

I solved my problem, I added

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED);
intentFilter.addAction(Intent.ACTION_PACKAGE_INSTALL);
intentFilter.addDataScheme("package");

before the line :

registerReceiver(installReceiver, intentFilter);
