Question

您好资深程序员！！！这是我得到的错误

这是我的build.gradle

apply plugin: 'com.android.application'

android {
compileSdkVersion 28
defaultConfig {
    applicationId "com.example.abdullah.my_fitness_app"
    minSdkVersion 15
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
//noinspection GradleCompatible
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
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'

//Add library
implementation 'com.google.firebase:firebase-core:10.2.0'
implementation 'com.google.firebase:firebase-database:10.2.0'
implementation 'info.hoang8f:fbutton:1.0.5'
implementation 'com.rengwuxian.materialedittext:library:2.1.4'
}
apply plugin: 'com.google.gms.google-services'

＃这是我的build.gradle（项目）＃

// Top-level build file where you can add configuration options common to 
all sub-projects/modules.

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath 'com.google.gms:google-services:4.0.1'

    // 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
}

任何解决此问题的方法？我知道这是由于有些重复，因为我是新手，我真的不知道是什么引起了错误，除了控制台说的是什么

错误：程序类型已存在：android.support.v4.app.BackStackRecord $ Op
