我在Android Studio中的清单文件中有许多“未解决的类”用于Appodeal程序包

Question

我正在尝试在Android Studio中实现从Appodeal公司（广告中介公司）到我的App的库，以便我可以运行它们的广告并通过我的App获利。 我遵循他们的指示： 首先，将必要的库放入libs文件夹中 其次，在gradle文件中添加必要的依赖项：

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
buildToolsVersion '27.0.3'
defaultConfig {
    applicationId 'com.languagematerial.lmmovies'
    minSdkVersion 23
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
    useLibrary 'org.apache.http.legacy'
    vectorDrawables.useSupportLibrary = true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
productFlavors {
}

packagingOptions {

    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/dependencies.txt'
    exclude 'META-INF/LGPL2.1'
}

}

repositories{
jcenter()
flatDir {
    dirs 'libs'
}

}

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

此操作成功同步。当我将软件包添加到清单文件时，就会出现问题。如图所示，其中大多数都带有红色的消息：未解析的类，好像所引用的库不在lib文件夹中，但显然它们在那里。那么这个问题是从哪里来的呢？甚至Appodeal的技术支持人员都无法帮助我。你有什么线索吗？
