https url

can't load https url images.
then i create class like
private PicassoTrustAll(Context context) {
OkHttpClient client = new OkHttpClient();
client.setHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String s, SSLSession sslSession) {
return true;
}
});
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
@Override
public void checkClientTrusted(
java.security.cert.X509Certificate[] x509Certificates,
String s) throws java.security.cert.CertificateException {
}

@Override
public void checkServerTrusted(
java.security.cert.X509Certificate[] x509Certificates,
String s) throws java.security.cert.CertificateException {
}

@Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[] {};
}
} };
try {
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
client.setSslSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
e.printStackTrace();
}

mInstance = new Picasso.Builder(context)
.downloader(new OkHttpDownloader(client))
.listener(new Picasso.Listener() {
@Override
public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
// Log.e("PICASSO", exception);
}
}).build();

}

public static Picasso getInstance(Context context) {
if (mInstance == null) {
new PicassoTrustAll(context);
}
return mInstance;
}
}

but i cant implement this class in baseslider
