SimpleMultiPartRequest无法正常工作-如何解决？

Question

当我编写SimpleMultiPartRequest时，它变成红色并且提示消失，这是我的问题，请告诉我如何在Android Studio中使用它

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    useLibrary 'org.apache.http.legacy'
    defaultConfig {
        applicationId "com.example.mdadi.cogniable"
        minSdkVersion 16
        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'
        }
    }
}
