Are you targetting MarshMallow? Please check your build.gradle
file. If it includes minSdkVersion=23
then you will have to also include the following in your build file.
android {
useLibrary 'org.apache.http.legacy'
}
The Apache libraries were deprecated and removed from the Android SDK in Android MarshMallow. Read more about this here: https://developer.android.com/about/versions/marshmallow/android-6.0-changes.html
