我在本教程的Android
中开发了推送通知应用程序:push notification in android app。我运行应用程序时会显示注册按钮。当我单击注册按钮时,注册成功后,我的设备上会显示通知。
如何将其包含在我自己的应用中?我的应用程序有一个xml解析示例应用程序。在添加任何新项目时,我希望在设备上显示(显示新订单)通知消息。它在这里自动生成。

我发布了Google Cloud Messaging的演示应用程序。
确保创建API级别等于或高于使用Google API的Android OS 2.2
的演示应用程序用户必须至少登录一个Google帐户才能使用此服务。
首先,您必须添加GCM library。
在我命名为GCMIntentService
的类上创建,扩展GCMBaseIntentService如下:
package com.example.gcmdemo;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import com.google.android.gcm.GCMBaseIntentService;
import com.google.android.gcm.GCMConstants;
public class GCMIntentService extends GCMBaseIntentService {
private static final String TAG = "Push Notification Demo GCMIntentService";
@Override
protected void onError(Context context, String errorId) {
if(GCMConstants.ERROR_ACCOUNT_MISSING.equalsIgnoreCase(errorId)) {
Log.v(TAG, "Error Account Missing");
} else if(GCMConstants.ERROR_AUTHENTICATION_FAILED.equalsIgnoreCase(errorId)) {
Log.v(TAG, "Error Authentication Failed");
} else if(GCMConstants.ERROR_INVALID_PARAMETERS.equalsIgnoreCase(errorId)) {
Log.v(TAG, "Error Invalid Parameters");
} else if(GCMConstants.ERROR_INVALID_SENDER.equalsIgnoreCase(errorId)) {
Log.v(TAG, "Error Invalid Sender");
} else if(GCMConstants.ERROR_PHONE_REGISTRATION_ERROR.equalsIgnoreCase(errorId)) {
Log.v(TAG, "Error Phone Registration Error");
} else if(GCMConstants.ERROR_SERVICE_NOT_AVAILABLE.equalsIgnoreCase(errorId)) {
Log.v(TAG, "Error Service Not Available");
}
}
@Override
protected void onMessage(Context context, Intent intent) {
// App Server Sends message as key value pairs
String value1 = intent.getStringExtra("key1");
String value2 = intent.getStringExtra("key2");
Log.v(TAG, "key1: "+value1 );
Log.v(TAG, "key2: "+value2 );
}
@Override
protected void onRegistered(Context context, String regId) {
Log.v(TAG, "Successfull Registration : "+regId);
}
@Override
protected void onUnregistered(Context context, String regId) {
Log.v(TAG, "Successfully Unregistred : "+regId);
}
@Override
protected String[] getSenderIds(Context context) {
return super.getSenderIds(context);
}
@Override
protected void onDeletedMessages(Context context, int total) {
super.onDeletedMessages(context, total);
}
@Override
protected boolean onRecoverableError(Context context, String errorId) {
return super.onRecoverableError(context, errorId);
}
}
以下是在以下演示活动中检查注册的方法:
package com.example.gcmdemo;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import com.google.android.gcm.GCMRegistrar;
public class MainActivity extends Activity {
private static final String TAG = "Push Notification Demo Activity";
private static final String SENDER_ID = "1069713227710";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
final String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
GCMRegistrar.register(this, SENDER_ID);
} else {
Log.v(TAG, "Already registered : "+regId);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
最后是演示清单:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.gcmdemo"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"

<uses-permission android:name="com.example.gcmdemo.permission.C2D_MESSAGE" />
<!-- App receives GCM messages. -->
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<!-- GCM connects to Google Services. -->
<uses-permission android:name="android.permission.INTERNET" />
<!-- GCM requires a Google account. -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<!-- Keeps the processor from sleeping when a message is received. -->
<uses-permission android:name="android.permission.WAKE_LOCK" />
<application

使用FCM发送推送通知
Google弃用了Google云消息传递(GCM)并推出了新的推送通知服务器,即Firebase云消息传递(FCM)。 FCM与GCM相同,FCM也是移动平台的跨平台消息传递解决方案
Firebase云消息传递可以发送三种类型的消息(Message types)
1.通知消息
2.数据消息
3.通知和数据消息
Firebase云消息传递集成步骤: -
1.在Firbase控制台中设置新项目或导入项目( https://firebase.google.com/ )
2.在Firebase应用程序中添加相同的应用程序包名称。
3.获取&#34; google-services.json&#34;将该文件放入项目的app文件夹中。此文件包含所有网址和Google服务密钥,因此请勿更改或编辑此文件。
4.在Project for Firebase中添加新的Gradle依赖项。
//app/build.gradle
dependencies {
compile 'com.google.firebase:firebase-messaging:9.6.0'
}
apply plugin: 'com.google.gms.google-services'
5.创建一个Class,其中包含我们在整个应用程序中用于FCM的所有常量值。
public class Config {
public static final String TOPIC_GLOBAL = "global";
// broadcast receiver intent filters
public static final String REGISTRATION_COMPLETE = "registrationComplete";
public static final String PUSH_NOTIFICATION = "pushNotification";
// id to handle the notification in the notification tray
public static final int NOTIFICATION_ID = 100;
public static final int NOTIFICATION_ID_BIG_IMAGE = 101;
public static final String SHARED_PREF = "ah_firebase";
}
6。创建一个名为MyFirebaseInstanceIDService.java的类,它将接收firebase注册ID,该ID对每个应用程序都是唯一的。注册ID用于向单个设备发送消息。
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = MyFirebaseInstanceIDService.class.getSimpleName();
@Override
public void onTokenRefresh() {
super.onTokenRefresh();
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
// Saving reg id to shared preferences
storeRegIdInPref(refreshedToken);
// sending reg id to your server
sendRegistrationToServer(refreshedToken);
// Notify UI that registration has completed, so the progress indicator can be hidden.
Intent registrationComplete = new Intent(Config.REGISTRATION_COMPLETE);
registrationComplete.putExtra("token", refreshedToken);
LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
}
private void sendRegistrationToServer(final String token) {
// sending gcm token to server
Log.e(TAG, "sendRegistrationToServer: " + token);
}
private void storeRegIdInPref(String token) {
SharedPreferences pref = getApplicationContext().getSharedPreferences(Config.SHARED_PREF, 0);
SharedPreferences.Editor editor = pref.edit();
editor.putString("regId", token);
editor.commit();
}
}
7.再创建一个名为MyFirebaseMessagingService.java的服务类。这将收到firebase消息。
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = MyFirebaseMessagingService.class.getSimpleName();
private NotificationUtils notificationUtils;
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.e(TAG, "From: " + remoteMessage.getFrom());
if (remoteMessage == null)
return;
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.e(TAG, "Notification Body: " + remoteMessage.getNotification().getBody());
handleNotification(remoteMessage.getNotification().getBody());
}
}
private void handleNotification(String message) {
if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
// app is in foreground, broadcast the push message
Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
pushNotification.putExtra("message", message);
LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
// play notification sound
NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
notificationUtils.playNotificationSound();
}else{
// If the app is in background, firebase itself handles the notification
}
}
/**
* Showing notification with text only
*/
private void showNotificationMessage(Context context, String title, String message, String timeStamp, Intent intent) {
notificationUtils = new NotificationUtils(context);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
notificationUtils.showNotificationMessage(title, message, timeStamp, intent);
}
/**
* Showing notification with text and image
*/
private void showNotificationMessageWithBigImage(Context context, String title, String message, String timeStamp, Intent intent, String imageUrl) {
notificationUtils = new NotificationUtils(context);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
notificationUtils.showNotificationMessage(title, message, timeStamp, intent, imageUrl);
}
}
8.在AndroidManifest.xml中添加这两个firebase服务MyFirebaseMessagingService和MyFirebaseInstanceIDService。
<!-- Firebase Notifications -->
<service android:name=".service.MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service android:name=".service.MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
<!-- ./Firebase Notifications -->
注意:
* 1.阅读Google文档Firebase Cloud Messaging *
2.如果您要将适用于Android的GCM客户端应用程序迁移到Firebase云消息传递,请按照以下步骤和文档(Migrate a GCM Client App)
进行操作3.Android示例教程和代码(Receive Reengagement Notifications)

个人建议您,除了GCM之外,还有其他名为Parse的库用于PushNotification,它与Google Cloud Messaging的工作方式相同,但它非常容易GCM
您只需下载JAR文件和简单的两三行代码即可获得推送通知
学习使用此网站https://parse.com/tutorials/android-push-notifications
即使您不必使用PHP或其为您提供设施的任何类型的服务器端代码
看,我会给你演示
Parse.initialize(this, "YOUR_APP_ID", "YOUR_CLIENT_KEY");
PushService.setDefaultPushCallback(this, YourDefaultActivity.class);
来自上面的代码足以接收推送通知
如果你想发送通知,他们会提供漂亮的用户界面,看看他们提供的用户界面的图片
