Conflict between Android SDK and Apache HTTP after API 23 update

Issue

In my project I am using these libraries:

compile 'org.apache.httpcomponents:httpclient:4.5.2'
compile 'org.apache.httpcomponents:httpcore:4.4.4'

Everything worked fine, until I updated Android Tools for API 23. Then when I try to perform HttpPost I get the following exception:

java.lang.NoSuchFieldError: INSTANCE
at org.apache.http.conn.ssl.SSLConnectionSocketFactory.<clinit>(SSLConnectionSocketFactory.java:144)
at org.apache.http.impl.client.HttpClientBuilder.build(HttpClientBuilder.java:966)
at org.apache.http.impl.client.HttpClients.createDefault(HttpClients.java:58)

And this is the library code where it happens:

public class SSLConnectionSocketFactory implements LayeredConnectionSocketFactory {

public static final String TLS   = "TLS";
public static final String SSL   = "SSL";
public static final String SSLV2 = "SSLv2";

@Deprecated
public static final X509HostnameVerifier ALLOW_ALL_HOSTNAME_VERIFIER
    = AllowAllHostnameVerifier.INSTANCE;

When looking at the external libraries, I can see the AllowAllHostnameVerifier class under android.jar:

And when using the code from the answer on this question: java.lang.NoSuchFieldError: org.apache.http.message.BasicLineFormatter.INSTANCE from Mashape Unirest in Java application

I get this output:

jar:file:/E:/Program%20Files/Eclipse%20Android%20SDK/adt-bundle-windows-x86_64-20140702/sdk/platforms/android-23/android.jar!/org/apache/http/conn/ssl/AllowAllHostnameVerifier.class

So I can see the build is taking this class from the SDK and not from the Apache libraries.

So the question is, how can I fix my classpath or other configuration necessary to direct the build to use these classes from Apache as before and not from the SDK?

Thanks in advance!

Solution

In short, just edit the android.jar file, remove the classes need being replaced by Apache libraries.
