Android Firebase （FCM）推送接入

news2025/1/8 6:03:27

官方文档：

向后台应用发送测试消息 | Firebase Cloud Messaging

1、根级（项目级）Gradlegradle的dependencies中添加：

    dependencies {
      ...

      // Add the dependency for the Google services Gradle plugin
      classpath 'com.google.gms:google-services:4.3.10'
    }

2、模块（应用级）Gradle 中添加 Google 服务插件：

plugins {
    id 'com.android.application'

    // Add the Google services Gradle plugin
    id 'com.google.gms.google-services'
    ...
}
或者
apply {
     plugin 'com.android.application'

    // Add the Google services Gradle plugin
     plugin "com.google.gms.google-services"
}

添加 Firebase Cloud Messaging Android 库的依赖项：（按官方的应该也是可以的）

    implementation(platform("com.google.firebase:firebase-bom:32.3.1"))
    implementation("com.google.firebase:firebase-analytics-ktx")
//    implementation("com.google.firebase:firebase-auth-ktx")
    implementation("com.google.firebase:firebase-firestore-ktx")
    implementation("com.google.firebase:firebase-messaging")
    // Firebase Cloud Messaging (Kotlin)
    implementation("com.google.firebase:firebase-messaging-ktx")

3、消息接收

AndroidManifest.xml中添加，接受类

        <service
            android:name=".BillionFirebaseMessagingService"
            android:exported="true">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>

                        addNotification(resTitle);

        Events.push("100410", params);
    }

    //添加提示
    private  void addNotification(String resTitle )
    {
        if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.POST_NOTIFICATIONS) == PackageManager.PERMISSION_GRANTED) {
            NotificationManagerCompat managerCompat = NotificationManagerCompat.from(this);

            NotificationChannel nc=newNotificationChannel(channelID, channelName);
            if (nc!=null)
            {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                    managerCompat.createNotificationChannel(nc);
                }

                pendingIntent=PendingIntent.getActivity(this, 0, nfIntent, PendingIntent.FLAG_IMMUTABLE);

            return channel;
        }

        return null;
    }
}

4、测试（google-services.json 记得放应用级中）

a、获取tokn

 //在firebase中检查google版本是否有问题
        GoogleApiAvailability.getInstance().makeGooglePlayServicesAvailable(this).addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                if (task.isSuccessful()) {
                    Log.d("Firebase", "onComplete: Play services OKAY");
                    //firebase 推送 （FCM）获取token（FCM令牌）
                    FirebaseMessaging.getInstance().getToken().addOnCompleteListener(new OnCompleteListener<String>() {
                        @Override
                        public void onComplete(@NonNull Task<String> task) {
                            if (!task.isSuccessful())
                            {
                                Log.w("Firebase", "Fetching FCM registration token failed", task.getException());
                                return;
                            }
                            // Get new FCM registration token
                            String ss= task.getResult();
                            Log.d("Firebase", "onComplete:token getResult "+ss);
                        }
                    });

                } else {
                    // Show the user some UI explaining that the needed version
                    // of Play services Could not be installed and the app can't run.
                }
            }
        });

b、用tokn就能对固定手机发送消息
