In the newest Android SDK version, 23, the following libraries have been removed.
org.apache.http.Header;
org.apache.http.message.BasicHeader;
We are also trying to compile for android-23 (6.0) and also get the same errors.
The “old” library/libraries are available in the following folder of your ADT-BUNDLE:
X:\adt-bundle\sdk\platforms\android-23\optional
It is called “org.apache.http.legacy.jar”.
We havn’t been able to solve the compilation yet. Trying to figure it out.
