Solution 1:

use this below code into your build.gradle instead import jar file :

useLibrary 'org.apache.http.legacy'

For reference check this code :

android {
compileSdkVersion 23
buildToolsVersion "24.0.0"
useLibrary 'org.apache.http.legacy'

defaultConfig {
    applicationId "com.application.abc"
    minSdkVersion 16
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
