before api level 24 my code is working fine but it is giving me error on api level 24( 7.0 Nougat). I am not getting what's going wrong with my code.

First Approach is here :

 <?xml version="1.0" encoding="utf-8"?> <network-security-config>
   <base-config> <trust-anchors> <certificates src="system"/>
   <certificates src="user"/> </trust-anchors> </base-config>
   <domain-config> <domain includeSubdomains="true">xyz.com</domain>
   <trust-anchors> <certificates src="@raw/my_ca"/> </trust-anchors>
   </domain-config> </network-security-config>

Inside manifest file :

android:network Security Config = "@xml/network_security_config" I have included network_security_config inside res/xml/network_security_config and ca certificate is inside res/raw/my_ca.pem

Second Approach is here :

 import org.apache.http.client.HttpClient; 
 import org.apache.http.conn.ClientConnectionManager;  
 import org.apache.http.conn.scheme.Scheme; 
 import org.apache.http.conn.scheme.SchemeRegistry;

      public ExSSLSocketFactory(KeyStore truststore) throws

         UnrecoverableKeyException {
         super(truststore);
     TrustManager x509TrustManager = new X509TrustManager() {

};

} @Override public Socket createSocket() throws
     IOException {

}
     public static HttpClient getHttpsClient(HttpClient client) {

     checkServerTrusted(X509Certificate[] chain, String authType) throws
     CertificateException {

 @Override public X509Certificate[]
     getAcceptedIssuers() { 
return null; 
}
 }; 
SSLContext sslContext = SSLContext.getInstance("TLS"); sslContext.init(null, new
     TrustManager[]{x509TrustManager}, null); SSLSocketFactory
     sslSocketFactory = new ExSSLSocketFactory(sslContext);
     sslSocketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
     ClientConnectionManager clientConnectionManager =
     client.getConnectionManager(); SchemeRegistry schemeRegistry =
     clientConnectionManager.getSchemeRegistry();
     schemeRegistry.register(new Scheme("https", sslSocketFactory, 443));
     return new DefaultHttpClient(clientConnectionManager,
     client.getParams()); 
} catch (Exception ex) 
{ return null; 
} } }

While making http connection :

public String CallWebService(String url, String soapAction, String envelope){


final HttpClient httpClient = ExSSLSocketFactory.getHttpsClient(new DefaultHttpClient());
    HttpParams params = httpClient.getParams();
    HttpConnectionParams.setConnectionTimeout(params, 150000);
    HttpConnectionParams.setSoTimeout(params, 150000);
    HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), true);
    HttpPost httppost = new HttpPost(url);
    httppost.setHeader("soapaction", soapAction);
    httppost.setHeader("Content-Type", "text/xml; charset=utf-8");

    String responseString = "";
    try
    {
        HttpEntity entity = new StringEntity(envelope);
        httppost.setEntity(entity);
        ResponseHandler<String> rh = new ResponseHandler<String>()
        {

            public String handleResponse(HttpResponse response) throws ClientProtocolException, IOException
            {

                HttpEntity entity = response.getEntity();
                StringBuffer out = new StringBuffer();
                byte[] b = EntityUtils.toByteArray(entity);
                out.append(new String(b, 0, b.length));
                return out.toString();
            }
        };

        responseString = httpClient.execute(httppost, rh);
        Log.d("Response is here....", "responseString :  " + responseString);
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

    // close the connection
    httpClient.getConnectionManager().shutdown();
    return responseString;
}

Still I am getting error:

Make sure that you have set TLS enabled from the server side.
