To solve this, please change all these lines of code:

dependencies {

    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support:design:25.3.1'
    compile 'com.astuetz:pagerslidingtabstrip:1.0.1'
    compile 'com.aurelhubert:ahbottomnavigation:0.1.3'
    compile 'com.facebook.android:facebook-android-sdk:4.1.0'
    compile 'com.google.firebase:firebase-core:15.0.0'
    compile 'com.google.firebase:firebase-messaging:15.0.0'
    compile 'com.google.firebase:firebase-storage:15.0.0'
    compile 'com.firebaseui:firebase-ui:0.4.2'
    compile 'com.google.firebase:firebase-database:15.0.0'
    compile 'com.theartofdev.edmodo:android-image-cropper:2.3.0'

Answer 2

Firebase was updated yesterday (5/2), causing the various firebase dependencies you are importing to go out of sync.

The solution is to update them to the latest version, which you can find by:

1. Go to Firebase release notes for the list of latest versions, or
2. open build.gradle file in Android Studio and see which Firebase dependencies are highlighted, put cursor above each of them to see the latest version number

Answer 3

try adding multiDexEnabled true in

android {
    compileSdkVersion 27
    defaultConfig {
          applicationId "quotspot.inext.quotspot"
    minSdkVersion 16
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"

        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true

    }
