Android Firebase （FCM）推送接入

news 2025/7/28 2:37:55

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 pluginclasspath '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 pluginid 'com.google.gms.google-services'...
}
或者
apply {plugin 'com.android.application'// Add the Google services Gradle pluginplugin "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

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

}

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>() {@Overridepublic 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>() {@Overridepublic void onComplete(@NonNull Task<String> task) {if (!task.isSuccessful()){Log.w("Firebase", "Fetching FCM registration token failed", task.getException());return;}// Get new FCM registration tokenString 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
