Class 'org.apache.http.conn.ssl.SSLSocketFactory' does not implement interface

Question

In my android app: app/build.gradle

  android {
        compileSdkVersion 28
        defaultConfig {
            minSdkVersion 18
            targetSdkVersion 28
            versionCode 427
            versionName "2.1.427"
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

dependencies {
    annotationProcessor "org.androidannotations:androidannotations:$AAVersion"
    annotationProcessor "org.androidannotations:ormlite:$AAVersion"

I use "org.apache.http" to create http requests.

When I start my app on Android 6.0 it's success start. And I success create http request and success get http response. Nice.

url = https://some_host/

But when I start my ap on Android 9.0 I success create http request, but not return http response. Here errror:

Here java snippet:

import org.apache.commons.io.IOUtils;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.StatusLine;
import org.apache.http.client.ClientProtocolException;

import org.apache.http.params.HttpParams;
import org.apache.http.util.EntityUtils;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
    HttpPost post = new HttpPost(url.toString());
                    post.setEntity(be);
                    be = null;
                    // Reporting purpose
                    requestStartDate = new Date();
                    HttpResponse httpResponse = client.execute(post);
                    post = null;
                    StatusLine statusLine = httpResponse.getStatusLine();

error in this line:

HttpResponse httpResponse = client.execute(post);

Add client.getConnectionManager().getSchemeRegistry().register( new Scheme("https", SSLSocketFactory.getSocketFactory(), 443) ); above HttpResponse httpResponse = client.execute(post); — Mandeep Singh

I had the same issue and putting this:

client.getConnectionManager().getSchemeRegistry().register( new Scheme("https", SSLSocketFactory.getSocketFactory(), 443) );

above the client.execute(post) line did solve my problem.
