[Android App 개발 스터디] #19 FCM 푸시알림

  이번에는 앱 관리자가 앱 사용자들에게 원하는 시간대에 푸시알림을 보낼 수 있는 FCM 푸시알림을 구현하는 법에 대해 배워볼 것이다.

(1) activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

  딱히 손을 대지 않았다. 그저 기본으로 제공되는 양식을 쓰면 될듯. 우리의 관심은 activity에 알림이 뜨는 것이 아닌 푸시알림이 뜨게 하는 것이기 때문이다.

(2) build.gradle (:app) 

plugins {
    id 'com.android.application'
}

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.example.pushtest"
        minSdkVersion 16
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

apply plugin: 'com.android.application'

apply plugin: 'com.google.gms.google-services'

dependencies {

    implementation 'androidx.appcompat:appcompat:1.3.1'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.0'
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
    implementation 'com.google.firebase:firebase-messaging:17.0.0'

}

  기본 제공 양식에서 dependencies 항목에 implementation 'com.google.firebase:firebase-messaging:17.0.0' 을 추가해줬다.

(3) build.gradle (프로젝트명)

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.2.2"
        classpath 'com.google.gms:google-services:4.3.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

  기본 제공 양식에서 dependencies 항목에 classpath 'com.google.gms:google-services:4.3.2' 를 추가해주었다.

    @Override
    public void onTokenRefresh() {
        super.onTokenRefresh();

    }

    private void sendRegistrationToServer (String token) {

    }

}

    private String msg,title;

    @Override

        Log.e(TAG,"onMessageReceived");

        title = remoteMessage.getNotification().getTitle();
        msg = remoteMessage.getNotification().getBody();

        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        PendingIntent contentintent = PendingIntent.getActivity(this,0,new Intent(this,MainActivity.class),0);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this,"test").setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle(title)
                .setContentText(msg)
                .setAutoCancel(true)
                .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                .setVibrate(new long[]{1,1000});

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0,mBuilder.build());

        mBuilder.setContentIntent(contentintent);
