FirebaseDatabase database = FirebaseDatabase.getInstance(); 
DatabaseReference myRef = database.getReference("message"); 

ich versucht habe, in den und aus dem onCreate() jedoch erhalte ich die folgende Fehler:

Das sind meine Gradle Konfigurationsdateien:

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.2' 

     // NOTE: Do not place your application dependencies here; they belong 
     // in the individual module build.gradle files 
     classpath 'com.google.gms:google-services:3.0.0' 
    } 
} 
allprojects { 
    repositories { 
     jcenter() 
    } 
} 
task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

und

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 25 
    buildToolsVersion "25.0.2" 
    defaultConfig { 
     applicationId "com1032.cw2.nv00075.nv00075_assignment2"

    } 
}
