How to ignore SSL error in Okhttp?

Question

I've Installed and turned the PacketCapture on, then When I request an API using Okhttp to my server, I get this exception.

javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

Is it possible to ignore SSL errors?

OkHttpClient.Builder allows you to add your own SSLContext and TrustManager. Here is the code from this gist which ignore all errors:

private static OkHttpClient getUnsafeOkHttpClient() {
    try {
        // Create a trust manager that does not validate certificate chains
        final TrustManager[] trustAllCerts = new TrustManager[]{
                new X509TrustManager() {
                    @Override
                    public void checkClientTrusted(java.security.cert.X509Certificate[] chain,
                                                   String authType) throws CertificateException {
                    }

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

                    @Override
                    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                        return new X509Certificate[0];
                    }
                }
        };

        // Install the all-trusting trust manager
        final SSLContext sslContext = SSLContext.getInstance("SSL");
        sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
        // Create an ssl socket factory with our all-trusting manager
        final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

        return new OkHttpClient.Builder()
                .sslSocketFactory(sslSocketFactory, (X509TrustManager) trustAllCerts[0])
                .hostnameVerifier(new HostnameVerifier() {
                    @Override
                    public boolean verify(String hostname, SSLSession session) {
                        return true;
                    }
                }).build();

    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

Note: This is an unsafe solution. Use it for debugging stuff.
