Студия Android ClassNotFoundException

После импорта внешних библиотек в мой проект каждый раз, когда я запускаю проект, я получаю ClassNotFoundException:

 Caused by: java.lang.NoClassDefFoundError: Class not found using the boot class loader; no stack available

JAR-файлы находятся внутри папки 'libs': libs

Iтакже добавлены зависимости в build.gradle: 

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "prm.soundpaint"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation files('libs/neuroph-core-2.94.jar')
    implementation files('libs/neuroph-imgrec-2.94.jar')
    implementation files('libs/neuroph-ocr-2.94.jar')
}

Он вылетает в строке, где инициализируется объект: 

private Runnable loadDataRunnable = new Runnable() {
    public void run() {
        InputStream irs = getResources().openRawResource(R.raw.m1);
        nnet = NeuralNetwork.load(irs);
    }
};

Я пытался решить эту проблему, отключив мгновенный запуск в Android Studio, нобез эффекта.Я также попытался:

  • удалить папку сборки, очистить и пересобрать проект
  • сделать недействительными кэши и перезапустить
  • перезагрузить устройство

  • включитьmultiDex в build.gradle и в файле манифеста:

    compile 'com.android.support:multidex:1.0.0' multiDexEnabled true android: name = "android.support.multidex.MultiDexApplication"

  • отключение preDexLibraries с помощью dexOptions {preDexLibraries false}

EDIT Снимок экрана рабочего пространства проекта

К сожалению, приложение по-прежнему вылетает при каждом запуске.У меня устройство с Android 5. Кто-нибудь знает, как решить эту проблему?
