    implementation 'com.google.firebase:firebase-database:16.0.1'
    implementation 'com.google.firebase:firebase-inappmessaging-display:17.0.0'
    implementation 'com.google.firebase:firebase-core:16.0.1'

classpath 'com.android.tools.build:gradle:3.0.1'

Let me know if any solution available for it.

Answer 1

classpath 'com.android.tools.build:gradle:3.1.4'

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.firebasedatabasedemo"
        minSdkVersion 16
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:multidex:1.0.3'
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.google.firebase:firebase-core:16.0.1'
    implementation 'com.google.firebase:firebase-database:16.0.1'
    implementation 'com.google.firebase:firebase-inappmessaging-display:17.0.0'


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

It's solved by changing gradle dependency to 3.1.4 version & by integrating multidex.
