After updating my Firebase and Play Services dependencies as well as the Play Services Plugin my project fails to build. I\'ve tried multiple Clean-Rebuilds and my app has M

Answer 1

Program type already present: android.arch.core.util.Function Message{kind=ERROR, text=Program type already present: android.arch.core.util.Function, sources=[Unknown source file], tool name=Optional.of(D8)}

I had the same problem above, and it was because i didn't include the core.

implementation 'com.google.firebase:firebase-core:16.0.1'

Noted some of your dependency is 16.0.1, would suggest you upgrade the core to 16.0.1 instead of 16.0.0.

Have enclosed my dependency below for reference, hope you find it useful.

implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.firebaseui:firebase-ui-database:4.1.0'

Try replacing gradle files with:

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.google.gms:google-services:3.2.1'
    }
}

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
        jcenter()
        google()
    }
}

And Module:app grandle with:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion "27.0.3"

    defaultConfig {
        applicationId "com.example.myapp"
        minSdkVersion 16
        targetSdkVersion 27
        multiDexEnabled true
    }

    buildTypes {

        debug{
            debuggable true
            minifyEnabled false
        }
        release {
            debuggable false
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
        }
    }
    dexOptions {
        javaMaxHeapSize "4g"
    }


    repositories {
        jcenter()
        google()
        maven { url 'https://maven.google.com' }
    }

Answer 3

I found the solution which some great guy posted on GitHub. Instead of downgrading your firebaseUI database, you can add arch common and runtime dependencies which are these:

//Arch
    implementation "android.arch.core:runtime:1.1.1"
    implementation "android.arch.core:common:1.1.1"

Just add these in your app: module dependencies section and you know build it.

Answer 4

The solution is to add the below implemention on your build.gradle in android studio. Hope it helps.

 implementation "android.arch.core:runtime:$version"
 implementation "android.arch.core:common:$version"

Answer 5

My project works with the latest version of firebase core, database, messaging and auth dependencies and latest classpath 'com.google.gms:google-services:4.0.1'

App/build.gradle

dependencies {

    // Tab Layout and ViewPager
    implementation 'com.android.support:design:27.1.1'

    // firebase dependencies
    // implementation 'com.firebaseui:firebase-ui-database:4.0.0' Source of error
    implementation 'com.google.firebase:firebase-core:16.0.0'
    implementation 'com.google.firebase:firebase-database:16.0.1'
    implementation 'com.google.firebase:firebase-messaging:17.0.0'
    implementation 'com.google.firebase:firebase-auth:16.0.1'
}

build.gradle

buildscript {
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:4.0.1'
    }
}

The problem evolves when adding implementation 'com.firebaseui:firebase-ui-database:4.0.0'

It shows this error:

Program type already present: android.arch.core.util.Function

Message{kind=ERROR, text=Program type already present: android.arch.core.util.Function, sources=[Unknown source file], tool name=Optional.of(D8)}

The solution was to downgrade implementation 'com.firebaseui:firebase-ui-database:4.0.0' to implementation 'com.firebaseui:firebase-ui-database:3.3.1' as follows:

App/build.gradle

dependencies {

    // Tab Layout and ViewPager
    implementation 'com.android.support:design:27.1.1'

    // firebase dependencies
    implementation 'com.firebaseui:firebase-ui-database:3.1.1' // No trouble in compiling
    implementation 'com.google.firebase:firebase-core:16.0.0'
    implementation 'com.google.firebase:firebase-database:16.0.1'
    implementation 'com.google.firebase:firebase-messaging:17.0.0'
    implementation 'com.google.firebase:firebase-auth:16.0.1'
}

I hope Google will solve this issue in future updates.

Hope that helped!
