如何使用Xamarin形式推送通知 [英] How to use Push Notifications in Xamarin Forms
问题描述
我使用Xamarin>表格的应用定位IOS，Android和WP 8。
I'm an app using Xamarin>Forms targeting IOS, android and WP 8.
我需要推送通知我的应用程序功能。
I need push notifications feature in my app.
我见过的pushsharp演示，似乎有希望的。但是，所有的C $ CS我见过的$是为每个平台单独进行。
I have seen the pushsharp demos and seems promising. But all the codes I had seen is done separately for each platform.
我想它在Xamarin.Forms项目来完成，在某处App.cs，这样我不需要重复code登记设备，以及如何处理推送通知应处理。
I would like it to be done in the Xamarin.Forms project, somewhere in the App.cs so that I dont need to repeat the code for registering device, and handle how push notifications should be processed.
任何帮助将大大AP preciated。示例codeS或教程引用的欢迎。
Any help would be greatly appreciated. Sample codes or tutorial references are welcome.
修改：我实现了它的基础上IDOT的回答。下面是在 链接 作为我的答案。
Edit : I implemented it based on Idot's answer. Here is the link for my answer.
推荐答案
我只是实现推送通知，前几天，我会在这里分享我的解决方案（基于的 PushSharp ）
I just implemented push notification a few days ago, and I'll share my solution here (based on PushSharp)
通过步指南：
1）在你共享的项目，创建一个名为接口 IPushNotificationRegister
1) In your shared project, create an Interface called IPushNotificationRegister
public interface IPushNotificationRegister
{
void ExtractTokenAndRegister();
}
此接口用于取回推令牌，然后将其发送到服务器。此令牌是每个设备独一无二的。
This interface is used for fetching the push token and then send it to the server. this Token is unique per device.
2）在共享proejct，应该调用 ExtractTokenAndRegister （用你喜欢的IOC，我把它叫做后立即登录）。
2) In Your shared proejct, you should invoke ExtractTokenAndRegister (using your favourite IOC, I called it right after login).
Android的执行情况：
3）添加接收器收听由谷歌GCM服务接收到的事件：
3) Add Receivers for listening to events received by Google GCM service:
A）
[BroadcastReceiver]
[IntentFilter(new[] { Intent.ActionBootCompleted })]
public class GCMBootReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
MyIntentService.RunIntentInService(context, intent);
SetResult(Result.Ok, null, null);
}
}
B）
[assembly: Permission(Name = "@PACKAGE_NAME@.permission.C2D_MESSAGE")]
[assembly: UsesPermission(Name = "android.permission.WAKE_LOCK")]
[assembly: UsesPermission(Name = "@PACKAGE_NAME@.permission.C2D_MESSAGE")]
[assembly: UsesPermission(Name = "com.google.android.c2dm.permission.RECEIVE")]
[assembly: UsesPermission(Name = "android.permission.GET_ACCOUNTS")]
[assembly: UsesPermission(Name = "android.permission.INTERNET")]
namespace Consumer.Mobile.Droid.PushNotification
{
[BroadcastReceiver(Permission = "com.google.android.c2dm.permission.SEND")]
[IntentFilter(new string[] { "com.google.android.c2dm.intent.RECEIVE" }, Categories = new string[] { "@PACKAGE_NAME@" })]
[IntentFilter(new string[] { "com.google.android.c2dm.intent.REGISTRATION" }, Categories = new string[] { "@PACKAGE_NAME@" })]
[IntentFilter(new string[] { "com.google.android.gcm.intent.RETRY" }, Categories = new string[] { "@PACKAGE_NAME@" })]
[IntentFilter (new[]{ Intent.ActionBootCompleted }, Categories = new[]{ Intent.CategoryDefault })]
public class GCMBroadcastReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
MyIntentService.RunIntentInService(context, intent);
SetResult(Result.Ok, null, null);
}
}
}
c）增加意图服务来处理通知
c) Add Intent service to process the notification
using Android.App;
using Android.Content;
using Android.Graphics;
using Android.Media;
using Android.OS;
using Android.Support.V4.App;
using Consumer.Mobile.Infra;
using Consumer.Mobile.Services.PushNotification;
using Java.Lang;
using XLabs.Ioc;
using TaskStackBuilder = Android.Support.V4.App.TaskStackBuilder;
namespace Consumer.Mobile.Droid.PushNotification
{
[Service]
public class MyIntentService : IntentService
{
private readonly ILogger _logger;
private readonly IPushNotificationService _notificationService;
private readonly IPushNotificationRegister _pushNotificationRegister;
public MyIntentService()
{
_logger = Resolver.Resolve<ILogger>();
_notificationService = Resolver.Resolve<IPushNotificationService>();
_pushNotificationRegister = Resolver.Resolve<IPushNotificationRegister>();
}
static PowerManager.WakeLock _sWakeLock;
static readonly object Lock = new object();
public static void RunIntentInService(Context context, Intent intent)
{
lock (Lock)
{
if (_sWakeLock == null)
{
// This is called from BroadcastReceiver, there is no init.
var pm = PowerManager.FromContext(context);
_sWakeLock = pm.NewWakeLock(
WakeLockFlags.Partial, "My WakeLock Tag");
}
}
_sWakeLock.Acquire();
intent.SetClass(context, typeof(MyIntentService));
context.StartService(intent);
}
protected override void OnHandleIntent(Intent intent)
{
try
{
Context context = this.ApplicationContext;
string action = intent.Action;
if (action.Equals("com.google.android.c2dm.intent.REGISTRATION"))
{
HandleRegistration(context, intent);
}
else if (action.Equals("com.google.android.c2dm.intent.RECEIVE"))
{
HandleMessage(context, intent);
}
}
finally
{
lock (Lock)
{
//Sanity check for null as this is a public method
if (_sWakeLock != null)
_sWakeLock.Release();
}
}
}
private void HandleMessage(Context context, Intent intent)
{
Intent resultIntent = new Intent(this, typeof(MainActivity));
TaskStackBuilder stackBuilder = TaskStackBuilder.Create(this);
var c = Class.FromType(typeof(MainActivity));
stackBuilder.AddParentStack(c);
stackBuilder.AddNextIntent(resultIntent);
string alert = intent.GetStringExtra("Alert");
int number = intent.GetIntExtra("Badge", 0);
var imageUrl = intent.GetStringExtra("ImageUrl");
var title = intent.GetStringExtra("Title");
Bitmap bitmap = GetBitmap(imageUrl);
PendingIntent resultPendingIntent = stackBuilder.GetPendingIntent(0, (int)PendingIntentFlags.UpdateCurrent);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
.SetAutoCancel(true) // dismiss the notification from the notification area when the user clicks on it
.SetContentIntent(resultPendingIntent) // start up this activity when the user clicks the intent.
.SetContentTitle(title) // Set the title
.SetNumber(number) // Display the count in the Content Info
.SetSmallIcon(Resource.Drawable.Icon) // This is the icon to display
.SetLargeIcon(bitmap)
.SetSound(RingtoneManager.GetDefaultUri(RingtoneType.Notification))
.SetContentText(alert); // the message to display.
// Build the notification:
Notification notification = builder.Build();
// Get the notification manager:
NotificationManager notificationManager =
GetSystemService(Context.NotificationService) as NotificationManager;
// Publish the notification:
const int notificationId = 0;
notificationManager.Notify(notificationId, notification);
}
private void HandleRegistration(Context context, Intent intent)
{
var token = intent.GetStringExtra("registration_id");
_logger.Info(this.Class.SimpleName, "Received Token : " + token);
if (_pushNotificationRegister.ShouldSendToken(token))
{
var uid = Android.Provider.Settings.Secure.GetString(MainActivity.Context.ContentResolver, Android.Provider.Settings.Secure.AndroidId);
_notificationService.AddPushToken(token, DeviceUtils.GetDeviceType(), uid);
}
}
private Bitmap GetBitmap(string url)
{
try
{
System.Net.WebRequest request =
System.Net.WebRequest.Create(url);
System.Net.WebResponse response = request.GetResponse();
System.IO.Stream responseStream =
response.GetResponseStream();
return BitmapFactory.DecodeStream(responseStream);
}
catch (System.Net.WebException)
{
return null;
}
}
}
}
D）实现接口 IPushNotificationRegister ：
using Android.App;
using Android.Content;
using Consumer.Mobile.Services;
using Consumer.Mobile.Services.PushNotification;
[assembly: Permission(Name = "@PACKAGE_NAME@.permission.C2D_MESSAGE")]
[assembly: UsesPermission(Name = "@PACKAGE_NAME@.permission.C2D_MESSAGE")]
// Gives the app permission to register and receive messages.
[assembly: UsesPermission(Name = "com.google.android.c2dm.permission.RECEIVE")]
// Needed to keep the processor from sleeping when a message arrives
[assembly: UsesPermission(Name = "android.permission.WAKE_LOCK")]
[assembly: UsesPermission(Name = "android.permission.RECEIVE_BOOT_COMPLETED")]
namespace Consumer.Mobile.Droid.PushNotification
{
public class PushNotificationRegister : IPushNotificationRegister
{
public override void ExtractTokenAndRegister()
{
string senders = AndroidConfig.GCMSenderId;
Intent intent = new Intent("com.google.android.c2dm.intent.REGISTER");
intent.SetPackage("com.google.android.gsf");
intent.PutExtra("app", PendingIntent.GetBroadcast(MainActivity.Context, 0, new Intent(), 0));
intent.PutExtra("sender", senders);
MainActivity.Context.StartService(intent);
}
}
}
的iOS实现：
4）在你的的AppDelegate ，添加下面的方法：
4) In your AppDelegate , add the following method:
A）
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
var deviceTokenString = deviceToken.ToString().Replace("<","").Replace(">", "").Replace(" ", "");
var notificationService = Resolver.Resolve<IPushNotificationService>();
var pushNotificationRegister = Resolver.Resolve<IPushNotificationRegister>();
if (pushNotificationRegister.ShouldSendToken(deviceTokenString))
{
var uid = UIDevice.CurrentDevice.IdentifierForVendor.AsString();
notificationService.AddPushToken(deviceTokenString, DeviceUtils.GetDeviceType(), uid);
}
}
b）实施 IPushNotificationRegister ：
using Consumer.Mobile.Services;
using Consumer.Mobile.Services.PushNotification;
using UIKit;
namespace Consumer.Mobile.iOS.PushNotification
{
public class iOSPushNotificationRegister : IPushNotificationRegister
{
public override void ExtractTokenAndRegister()
{
const UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound;
UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);
}
}
}
关于WP，我并没有实现它。
Regarding WP, I didn't implemented it.
如果您需要使用PushSharp在服务器端的code，让我知道。
If you need the code in the server side using PushSharp, let me know.
您可以检查客户端的样本，我根据我的解决方案这里
