Apache HTTP connection with Android 6.0 (Marshmallow)

Solution 1:

This page discusses the removal of the Apache HTTP classes, and it suggests a workaround as well:

To continue using the Apache HTTP APIs, you must first declare the following compile-time dependency in your build.gradle file:

   android {
       useLibrary 'org.apache.http.legacy'
   }

In my case Android Studio still complained that it couldn't find these classes, but the app did build and run.

The page does recommend you move to HttpURLConnection, though.

Solution 2:

According to the API 22-23 diff changes, the org.apache.http.* packages have been removed as of Android 6.0 (Marshmallow) API Level 23.
