Could not find support-media-compat.aar

Question

Trying Firebase to an android gradle app. As soon as I add the firebase dependency I get the following build error.

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all files for configuration ':app:debugCompileClasspath'.

It looks like it's only searching jcenter. But every reference of jcenter has other repos listed to search.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:3.2.0"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

        classpath 'com.google.gms:google-services:4.2.0' // google-services plugin
    }
}

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

app/build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"
    defaultConfig {
        applicationId "io.nme.samples.displayingabitmap"

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    api fileTree(dir: 'libs', include: ['*.jar'])
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    api 'com.android.support:appcompat-v7:24.2.1'
    api 'com.android.support:support-v4:24.2.1'

    testImplementation 'junit:junit:4.12'

    dependencies {

        api project(':extension-api')
        api project(':haxe-firebase')
    }

    implementation 'com.google.firebase:firebase-core:16.0.4'
}

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'

What am I missing here?

Show your app-level Gradle too. – Unanimity

Okay, I edited the main question. – Chair

Answer 1

api 'com.android.support:appcompat-v7:24.2.1'
api 'com.android.support:support-v4:24.2.1'

That's your problem right there. Even without Firebase, this should've been causing issues. You're targeting and building with API 28, but your support dependencies are at API 24. Change them to use 28.0.0.

Also check your extension-api and haxe-firebase projects and make sure they're using the latest compile and SDK versions, as well as build tools version and support library versions.

Thank you! That did it. Didn't know those had to be in sync. – Chair

Can you please specify the path to go and edit this ? – Gradation

Answer 2

I came across the same issue about locating libraries. However by adjusting the repositories order, this issue has been resolved.

repositories {
    google()
    jcenter()
    // others
}

It seems that a maven site hosted by google is what we're looking for in the first place.

BTW, maven { url 'https://maven.google.com'} is used for Gradle version lower than 4.1 and google() is the newer form of that. See also this doc.

thanks a lot, spent more than 30 min before trying this. – Egerton

I tried this as a shot in the dark and it worked - then saw that you commented this. wow. just wow. – Sonics

Answer 3

You have to Replace 26.1.0 and use support library of version 28.0.0

I have no reference to 26.1.0 in my project. Not sure how I could do that. – Chair

Answer 4

use below

buildscript {
ext.kotlin_version = '1.2.20'

repositories {
    jcenter()
}

dependencies {
    classpath 'com.android.tools.build:gradle:2.3.3'2.3.3
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3'
    classpath 'com.github.dcendents:android-maven-gradle-plugin:2.0'
}
}

allprojects {
repositories
        {
            maven { url "https://dl.google.com/dl/android/maven2/" }
            maven { url "http://jcenter.bintray.com/" }
            maven { url 'https://plugins.gradle.org/m2/'}
            maven { url "https://maven.google.com" }
            maven { url 'https://jitpack.io' }
            mavenCentral()
            flatDir {
                dirs 'libs'
            }
        }
}
