Question

我在我的应用中集成了播放服务和firebase。当我运行应用程序时，我收到此错误

cannot access zzbfm
class file for com.google.android.gms.internal.zzbfm not found

这是我的顶级gradle

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.2'


    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    classpath 'com.google.gms:google-services:4.0.1'
}
}

allprojects {
repositories {
    google()
    jcenter()
}
tasks.withType(JavaCompile) { options.deprecation = true }
}

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

这是我的app level gradle

apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
    applicationId "ima.rvtech"
    minSdkVersion 23
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

}

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

当我尝试获取remotemessage conntent时，我收到指向MessageService类中指向的错误

public class FCMMessageService extends FirebaseMessagingService {

@Override
public void onMessageReceived(RemoteMessage message) {
    sendMyNotification(message.getNotification().getBody());
}


private void sendMyNotification(String message) {

    //On click of notification it redirect to this Activity
    Intent intent = new Intent(this, ActivityHome.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

    Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this,"x")
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle("My Firebase Push notification")
            .setContentText(message)
            .setAutoCancel(true)
            .setSound(soundUri)
            .setContentIntent(pendingIntent);

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

    notificationManager.notify(0, notificationBuilder.build());
}
}

已经检查了其他问题中提到的解决方案，但这些答案都没有奏效。

任何解决方案？

您不能混合版本＆lt; = 12和版本＆gt; = 15的Firebase库。

implementation 'com.google.firebase:firebase-core:16.0.0'
implementation 'com.google.firebase:firebase-auth:11.6.2'
implementation 'com.google.firebase:firebase-messaging:11.8.0'

最简单的解决方法是将所有这些升级到版本16或更高版本：

implementation 'com.google.firebase:firebase-core:16.0.0'
implementation 'com.google.firebase:firebase-auth:16.0.1'
implementation 'com.google.firebase:firebase-messaging:17.0.0'

所有这些版本都来自setting up Firebase for Android文档，因此请务必在此处查看最新更新。

背景：在版本12及更低版本中，项目中所有Firebase（和Play服务）库的版本必须完全相同。在15版之后，您可以混合版本。但是没有办法在单个项目中混合使用＆lt; = 12和＆gt; = 15个库。

无法访问zzbfm类文件zzbfm找不到，firebase，android？
