Java – Android studio Dalvik VM cannot find class

I'm trying to figure out how to fix the errors in the legacy Android projects I've migrated to Android studio I hope this is good for my build The gradle script is even more problematic The class library works normally during coding, and is completed after completion

I tried closing the Android studio, running gradlew clean, and then reopening it in Android studio, but it didn't work

This is my settings Gradle script

include ':app',':imageloader-core-1.6.1'

This is my project build Gradle script

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
        classpath 'jp.leafytree.gradle:gradle-android-scala-plugin:1.3.1'
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }
}

This is my app build Gradle script

apply plugin: 'com.android.application'
apply plugin: 'jp.leafytree.android-scala'

android {
    compileSdkVersion 19
    buildToolsVersion "21.1.1"

    defaultConfig {
        applicationId "com.andre.andredublin"
        minSdkVersion 14
        targetSdkVersion 19
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.txt'
        }
    }

    sourceSets {
        main {
            scala {
                srcDir 'src'
            }
        }
    }

    dexOptions {
        preDexLibraries false
        javaMaxHeapSize "2g"
    }
}

dependencies {
    compile 'com.facebook.android:facebook-android-sdk:3.21.1'
    compile 'com.android.support:multidex:1.0.0'
    compile 'org.scala-lang:scala-library:2.11.4'
    compile 'io.spray:spray-json_2.11:1.3.1'
    compile 'org.scaloid:scaloid_2.11:3.6.1-10'
    compile 'com.loopj.android:android-async-http:1.4.4'
    compile 'com.google.code.gson:gson:2.2.2'
    compile 'net.hockeyapp.android:HockeySDK:3.5.0'
    compile project(':imageloader-core-1.6.1')
}

afterEvaluate {
    tasks.matching {
        it.name.startsWith("dex")
    }.each { dx ->
        if (dx.additionalParameters == null) {
            dx.additionalParameters = []
        }
        dx.additionalParameters += "--multi-dex"
        dx.additionalParameters += "--main-dex-list=$rootDir/main-dex-list.txt".toString()
    }
}

The following are the errors I received from the log when running in genymotion

Did you forget to reference any jar files? Library project imageloader-core-1.6 1 are any errors reported (anything underlined in red)? The same error occurred after the build - > clean project? The same error occurs after file - > invalidate cache?

Sometimes I help gradle compile path_to_jar_file, but as far as I know, this has been fixed in all newer Android studios Which as version are you using?
