谷歌Android的导入类文件存在问题 _Android

恢弘志士之气，不宜妄自菲薄。这篇文章主要讲述谷歌Android的导入类文件存在问题相关的知识，希望能为你提供帮助。
我正在使用firebase C.M.在我的应用程序中创建推送通知模块。但是，当我构建解决方案时，我收到一个错误：

error: cannot access zza class file for com.google.android.gms.common.internal.safeparcel.zza not found

这是我的gradle项目：

// Top-level build file where you can add configuration options common to all sub-projects/modules.buildscript {repositories { jcenter() google() } dependencies { classpath 'com.android.tools.build:gradle:3.1.4' classpath 'com.google.gms:google-services:3.0.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } }allprojects { repositories { google() jcenter() } }task clean(type: Delete) { delete rootProject.buildDir }

【谷歌Android的导入类文件存在问题】并且gradle app有依赖关系：

dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support.constraint:constraint-layout:1.1.0' implementation 'com.squareup.retrofit2:retrofit:2.3.0' implementation 'com.squareup.retrofit2:converter-gson:2.3.0' implementation 'com.google.code.gson:gson:2.8.0' implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1' implementation 'com.squareup.okhttp3:okhttp:3.8.0' implementation 'org.greenrobot:eventbus:3.0.0' implementation 'com.jakewharton:butterknife:8.6.0' implementation 'com.android.support:design:26.1.0' implementation 'com.android.support:support-v4:26.1.0' implementation 'com.android.support:recyclerview-v7:26.1.0' implementation 'uk.co.chrisjenx:calligraphy:2.3.0' implementation 'com.android.support:cardview-v7:21.0.+' implementation 'de.hdodenhof:circleimageview:2.2.0' implementation 'com.google.firebase:firebase-core:16.0.1' implementation 'com.google.firebase:firebase-messaging:10.2.1' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.2' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' annotationProcessor 'com.jakewharton:butterknife-compiler:8.6.0' implementation('com.crashlytics.sdk.android:crashlytics:2.9.4@aar') { transitive = true } }apply plugin: 'com.google.gms.google-services'

我认为这个问题与这个导入有关

import com.google.firebase.messaging.RemoteMessage;

我的方法onMessageReceived：

private static final String ADMIN_CHANNEL_ID ="admin_channel"; @Override public void onMessageReceived(RemoteMessage remoteMessage) {notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); if (android.os.Build.VERSION.SDK_INT > = android.os.Build.VERSION_CODES.O) { setupChannels(); }int notificationId = new Random().nextInt(60000); Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, ADMIN_CHANNEL_ID) .setContentTitle(remoteMessage.getData().get("title")) .setContentText(remoteMessage.getData().get("message")) .setAutoCancel(true) .setSound(defaultSoundUri); NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.notify(notificationId /* ID of notification */, notificationBuilder.build()); }

难道我做错了什么？我已经检查了很多次，我没有发现错误！谢谢！！！！！
