androidpn的学习研究（四）androidpn-client客户端几个类说明

  在androidpn的客户端几个重要的类：

                ServiceManager：管理消息服务和加载相关的配置。

                ConnectivityReceiver：处理网络状态的广播。

                NotificationReceiver：处理服务端发送的推送消息。

                NotificationService：后台服务用户响应服务端的消息。需要在AndroidManifest.xml.注册。

                NotificationSettingsActivity：推送信息设置页面。

                PersistentConnectionListener：监控连接关闭和重连事件的监听。

                PhoneStateChangeListener：监听手机状态的事件监听类。

                ReconnectionThread：重连的线程类。

                Notifier：客户端发送通知的类。

                NotificationIQ：消息的数据包。

ServiceManager中获取属性信息的方法：

    private Properties loadProperties() {
        //        InputStream in = null;
        //        Properties props = null;
        //        try {
        //            in = getClass().getResourceAsStream(
        //                    "/org/androidpn/client/client.properties");
        //            if (in != null) {
        //                props = new Properties();
        //                props.load(in);
        //            } else {
        //                Log.e(LOGTAG, "Could not find the properties file.");
        //            }
        //        } catch (IOException e) {
        //            Log.e(LOGTAG, "Could not find the properties file.", e);
        //        } finally {
        //            if (in != null)
        //                try {
        //                    in.close();
        //                } catch (Throwable ignore) {
        //                }
        //        }
        //        return props;

        Properties props = new Properties();
        try {
            int id = context.getResources().getIdentifier("androidpn", "raw",
                    context.getPackageName());
            props.load(context.getResources().openRawResource(id));
        } catch (Exception e) {
            Log.e(LOGTAG, "Could not find the properties file.", e);
            // e.printStackTrace();
        }
        return props;
    }

SharedPreferences的使用：

        sharedPrefs = context.getSharedPreferences(
                Constants.SHARED_PREFERENCE_NAME, Context.MODE_PRIVATE);
        Editor editor = sharedPrefs.edit();
        editor.putString(Constants.API_KEY, apiKey);
        editor.putString(Constants.VERSION, version);
        editor.putString(Constants.XMPP_HOST, xmppHost);
        editor.putInt(Constants.XMPP_PORT, Integer.parseInt(xmppPort));
        editor.putString(Constants.CALLBACK_ACTIVITY_PACKAGE_NAME,
                callbackActivityPackageName);
        editor.putString(Constants.CALLBACK_ACTIVITY_CLASS_NAME,
                callbackActivityClassName);
        editor.commit();

获取手机的设备id：

TelephonyManager       telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        // wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        // connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

        // Get deviceId
        deviceId = telephonyManager.getDeviceId();

 Notifier中发送通知的方法：

            // Notification
            Notification notification = new Notification();
            notification.icon = getNotificationIcon();
            notification.defaults = Notification.DEFAULT_LIGHTS;
            if (isNotificationSoundEnabled()) {
                notification.defaults |= Notification.DEFAULT_SOUND;
            }
            if (isNotificationVibrateEnabled()) {
                notification.defaults |= Notification.DEFAULT_VIBRATE;
            }
            notification.flags |= Notification.FLAG_AUTO_CANCEL;
            notification.when = System.currentTimeMillis();
            notification.tickerText = message;

            //            Intent intent;
            //            if (uri != null
            //                    && uri.length() > 0
            //                    && (uri.startsWith("http:") || uri.startsWith("https:")
            //                            || uri.startsWith("tel:") || uri.startsWith("geo:"))) {
            //                intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
            //            } else {
            //                String callbackActivityPackageName = sharedPrefs.getString(
            //                        Constants.CALLBACK_ACTIVITY_PACKAGE_NAME, "");
            //                String callbackActivityClassName = sharedPrefs.getString(
            //                        Constants.CALLBACK_ACTIVITY_CLASS_NAME, "");
            //                intent = new Intent().setClassName(callbackActivityPackageName,
            //                        callbackActivityClassName);
            //                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            //                intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
            //            }

            Intent intent = new Intent(context,
                    NotificationDetailsActivity.class);
            intent.putExtra(Constants.NOTIFICATION_ID, notificationId);
            intent.putExtra(Constants.NOTIFICATION_API_KEY, apiKey);
            intent.putExtra(Constants.NOTIFICATION_TITLE, title);
            intent.putExtra(Constants.NOTIFICATION_MESSAGE, message);
            intent.putExtra(Constants.NOTIFICATION_URI, uri);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.setFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
            intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
            intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

            PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
                    intent, PendingIntent.FLAG_UPDATE_CURRENT);

            notification.setLatestEventInfo(context, title, message,
                    contentIntent);
            notificationManager.notify(random.nextInt(), notification);

androidpn用户名和密码来源：

XmppManager的注册任务（RegisterTask）中run方法：

            if (!xmppManager.isRegistered()) {
                final String newUsername = newRandomUUID();
                final String newPassword = newRandomUUID();

                Registration registration = new Registration();

                PacketFilter packetFilter = new AndFilter(new PacketIDFilter(
                        registration.getPacketID()), new PacketTypeFilter(
                        IQ.class));
